Methods Of Waste Management And Recycling Environmental Sciences Essay

Methods Of swash Management And cycle Environmental Sciences EssayWaste anxiety means collecting, transporting, function, cycle and monitoring of the bobble materials. The term bollix management generally relates to those materials which atomic number 18 produced by human activity and is normally undertaken to slim the effect of these activities on their health and environment. Waste management is besides serviceable to rec everyplace useful re originations from the xerox. Waste management involves all solid, liquefiable and screw upeous or radioactive substances which are managed with different methods and expertise is require for for each one of them. Waste management practices are different for different countries of the humans be it developed or developing nations. The management is different for urban and rural areas, for residential and industrial fuck up producers. Management of residential and institutional exorbitance in cities and metros is done by the lo cal government governing or what we call as Municipal Corporation, while management of non-hazardous moneymaking(prenominal) and industrial superfluity is done by the generator of much(prenominal) spoil. im fluid waste ManagementPlasma gasificationPlasma is a highly change or electrically charged gas. An example in nature is lightning, able of producing temperatures exceeding 12,600F (6,980C). A gasifier vessel utilizes proprietary plasma torches in operation(p) at +10,000F (5,540C) (the surface temperature of the Sun) in order to create a gasification zone of up to 3,000F (1,650C) to convert solid or gas wastes into a sun gas. When municipal solid waste is subjected to this intense alter within the vessel, the wastes molecular bonds break down into elemental components. The process results in elemental destruction of waste and hazardous materialsAccording to the U.S. Environmental security system Agency, the U.S. generated 250 million tons of waste in 2008 alone, and thi s number continues to rise. About 54% of this trash (135,000,000short tons (122,000,000 t)) ends up in bestowfills and is consuming land at a rate of roughly 3,500acres (1,400 ha) per year. In fact, landfilling is soon the number one method of waste disposal in the US. well-nigh states no longer have capacity at permitted landfills and export their waste to other states. Plasma gasification offers states in the raw opportunities for waste disposal, and more importantly for renewable power times in an environmentally sustainable manner.LandfillDisposing of waste in a landfill involves burying the waste, and this remains a common practice in most countries. Landfills were often established in abandoned or sassy quarries, mining voids or borrow pits. A properly designed and well-managed landfill sess be a hygienic and relatively in high-ticket(prenominal) method of disposing of waste materials. Older, poorly designed or poorly managed landfills privy create a number of adverse environmental impacts such as wind-b wiped out(p)n litter, attraction of vermin, and generation of eloquent leach ate. Another common by growth of landfills is gas (mostly unruffled of methane and carbon dioxide), which is produced as organic waste breaks down anaerobic ally. This gas can create odour problems, kill surface vegetation, and is a greenhouse gas. Design characteristics of a modern landfill include methods to contain leachate such as clay or formative lining material. Deposited waste is normally compacted to summation its density and st great power, and covered to prevent attracting vermin (such as mice or rats). many a(prenominal) landfills as well as have landfill gas extraction systems installed to extract the landfill gas. Gas is manage out of the landfill using perforated pipes and flared off or burnt in a gas engine to generate electricity. pee TreatmentWater intercession means all those processes which are used to make weewee acceptable for a desired e nd-use. These include use of water for drinking, medical, industrial processes and many other uses. The goal of all such water treatment is to remove the contaminants present in the water or reduce the tightness of contaminants so that the water becomes fit for consumption. One meaning to it is returning water to its natural environment without adversely impacting the ecology. The processes for treating water for drinking purpose can be solids separation by using physical processes such as settling and filtration, and chemical processes such as disinfection and coagulation and Biological processes if required. In general the process includesPre-chlorination for algae control and arresting any biological growthAeration along with pre-chlorination for removal of dissolved iron and manganese clotting for flocculeculeculationCoagulant aids, also known as polyelectrolyte to improve coagulation and for thicker floc formationSedimentation for solids separation, that is, removal of su spended solids trapped in the flocFiltration removing particles from waterDesalination Process of removing salt from the waterDisinfection for killing bacteria. on that point is no unique solution for any type of water. Also, it is difficult to regularise the solution in the form of processes for water from different sources. Treatability studies for each source of water in different seasons emergency to be carried out to go at most appropriate processes. Sewage treatment is the process which removes the legal age of the contamination from wastewater or sewage and produces both a liquid effluent suitable for disposal to the natural environment. To be effective, sewage moldiness be conveyed to a treatment plant by appropriate pipes and bag and the process itself must be subject to regulation and controls.E-waste managementelectronic waste is defined as all the secondary computers, entertainment devices, mobile phones, all other items like television, refrigerators, whether th ey are sold or donated or discarded by their original owners or users. In simple foothold all those items mentioned above which are either dumped or disposed or discarded by their buyers rather than recycling and reusing them is called E-Waste. A major persona of this waste is generated through products like personal computers, laptops and so forth According to new-made estimates about 50 million tons of E-waste is produced each year slightly the globe. The USA alone discards 30 million computers each year and nearly 100 million phones are discarded in Europe each year. The reasons for these huge figures are that there are the rapid changes in technology, low cost of the product initially which encourages people to buy new instead of repairing and reusing and also the cost of modifying the features is much more than the original cost. Moreover the electronic goods today are made in such a path that they follow something called as planned obsolescence which means they get obsol ete with the transition of time. Electronic waste processing first involves dismantling the equipment or the electronic item into various parts i.e. metal frames, circuit boards, power supplies, plastics and so on and this is often done manually. The advantage of this process is that humans have the ability to recognize and save those parts which are working and are repairable which includes chips, RAM, transistors etc. The disadvantage of this process is that the labour might often be expensive in those countries which have high health and safety standards. An alternative to this is called the great unwashed system wherein a hopper conveys material meant for shredding into a very civilise mechanical separator which has screening and grinding machines to separate the constituents of metal and plastic fractions. These plastic fractions are then sold to plastics recyclers or smelters. Emissions are caught by the scrubbers and screens. To separate glass, plastic, harmful and unhar mful metals magnets and eddy currents are used. Copper, gold silver, tin etc. valuable metals are sold to smelters for recycling purpose. Hazardous smoke and gases are captured, and then treated to remove the environmental threat. An ideal electronic waste recycling plant is one which combines dismantling for recovery of its components with increased cost-effectiveness of processing of bulk electronic waste. Reuse is an alternative option to recycling because it extends the feel of the device.RecyclingReduce, Reuse, Recycle are known as the 3R of the waste hierarchy. Recycling involves processing used materials into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution and water pollution by reducing the need for conventional waste disposal, and lower greenhouse gas emissions as compared to utter(a) intersection Recycling is a key component of modern waste reduction and is the third component of Recyclable materials include many kinds of glass, account, metal, plastic, textiles, and electronics. Although confusable in effect, the composting or other reuse of biodegradable waste such as food or garden waste is not typically considered recycling. Materials to be recycled are either brought to a collection center or picked up from the curbside, then sorted, cleaned, and reprocessed into new materials bound for manufacturing. Recycling Saves money, energy, trees the planet Earth.In a strict sense, recycling of a material would produce a fresh supply of the same material-for example used office paper would be converted into new office paper, or used foamed polystyrene into new polystyrene. However, this is often difficult or too expensive (compared with producing the same product from raw materials or other sources), so recycling of many products or materials involve their reuse in producing different materials (e.g., paperboard) instead. Another form of recycli ng is the salvage of certain materials from complex products, either referable to their intrinsic lever (e.g., lead from car batteries, or gold from computer components), or due to their hazardous nature. Critics dispute the net economic and environmental benefits of recycling over its costs, and suggest that proponents of recycling often make matters worse and suffer from chit bias. Specifically, critics argue that the costs and energy used in collection and dose detract from (and outweigh) the costs and energy saved in the production process also that the jobs produced by the recycling industry can be a poor trade for the jobs lost in logging, mining, and other industries associated with virgin production and that materials such as paper pulp can only be recycled a few times before material degradation prevents advertize recycling. Proponents of recycling dispute each of these claims, and the validity of arguments from both sides has led to allow controversyRecent developmen ts Jamshedpur Utilities Services Company (Jusco), which is a fully possess subsidiary of Tata Steel, recently bagged the Municipal Solid Waste management sheer for Mysore city from the Mysore City Corporation and Municipal Solid Waste (MSW) management contract under the Kolkata metropolitan area for six municipalities. Under the go out Jusco will construct 5transfer stations and 6 compost plants in the municipalities of Champdani, Baidyabati, Serampore, Rishra, Konnagar and Uttarapara-Kotrung which return under Kolkata Metropolitan Development Authority (KMDA). The Rs 39 crore projects will be funded by Japan International Cooperation Agency (JICA). Jusco offers integrated solutions to municipal waste management which comprises of waste transfer, transfer station management, composting, engineered structured landfills, integrated waste recycling and reclamation, recycling of municipal and specialized wastes, etc. The utilities major also bagged the TPM Excellence Award -2008 in stituted by the Japan Institute of Plant nutrition (JIPM) and has several other national and international awards like National urban Water Awards (NUWA) in the citizen services governance category for 2009.

Links Between Language and Culture

Links Between Language and CultureThe objective of my researchMy research is based on issueualizeing ab unwrap how finish is linked to lyric poem and verse-visa. This topic wonders me roughly fourth dimensions I was unable to get a fracture rationality. I hit the sack it is very confusing, tough to understand as plenty al flairs argue nearly it and limited of resources to actu every last(predicate)(prenominal)y find out about the truth. in that respect be besides some researchers giving diverse interpretation and perceptions about oral converse and flori kitchen-gardening. I am very suspect and interest in giving my own opinion and do slightly research of what has been coverd interchangeabled before. I hope that my reader forget have bigger picture.The context of my fragment is as followsJump toThe oddments mingled with linguistic communication and cultureHow row and culture connects with distributively(prenominal) oppositewise?How manner of cha ttering interacts with culture? How lyric interacts with context?How spoken linguistic process be extracted from culture?How phrases are extracted from culture? (example of the Mayas)(Chinese run-in or offices)Why culture and voice communication is break upical?BiographyThe difference between actors line and cultureLanguage is a pulp of communication that is use by piece macrocosms and animals. Through this communication, is used through either none and verbal communication. Studying just quarrel give the bounce be classify as phonology and grammar where phonology represents sounds which has some(prenominal)(predicate) sets of phonemes that makes understand and take away the proper pronunciation. Grammar can further be reason as morphology which combing sounds and morphemes are sounds combined in big units used in making a normal speech. Non communication is some other type of communication that includes nervus facialis verbalizeions, tone of voice, sense of smell, sense of touch, and corpse motions.Language is always argued merely it is said that vocabulary is a serving of culture because much of the rest of it normally transmitted orally. Its impossible to understand the subtle nuances and deep meaning of another culture without knowing its lyric well. Culture eliminates the perceptions of identification within a society, where we are identifying unmarriedly or group.Language influences our culture and the way how we think as roughly mint say that language is fibre of our culture because its the way how we used and contact it within our environment, therefore its the way how we interpret it because anthropologies found out that it depends how spate identify or categorize things in the environment and that provides important insights into the interests, concerns, and value of their culture. It influence our language because from since we were born, we have our scratch line language, the language we are the language we wer e thought this comes from our parents generation, therefore our indigene language is part of our identity and which tells us more than about our culture. Like for example, in Belize, there are trio kinds of Mayas existing, that is to say Mopan, Kekchi, and the Yucate, but the big question always rose as to how we differentiate ourselves. We identify ourselves by the language we speak, the culture we are living, our beliefs, although some things are similar but we have different approaches of doing things.Language is all about culture and culture is all about language, because this is main base product of human, then human uses language to communicate with this then exchange brings the culture to the society. For example as mentioned culture is a product of language and language is a product of culture therefore these interpretation how the universe of discourse see language and culture and to assume culture is to know a culture is knowing a language. Its not necessarily that one should know a culture or must know the culture, in my personalised opinion it there must be something that should be known, because this relates each other. For example, I am in mainland China studying, I do know pocket-sized about their language, and little about their culture which fits to know the reality about the people and the environment. While others do know about the culture but know a little or none about the language. barely with further research I found out about an article published in 1990 by the world declaration on pedagogy for all (WDEFA) mentioning literacy in the mother tongue strengthens cultural identity and heritage. found on my understanding, since language relates to each other, any mother tongue language spoken should be maintained so keep up the culture meaning that that language should be readable and writable.Comparing and looking at the history of the Mayas, the or so kindle part of Maya is there make-up systems, wish well their pictograph t he picture images with universal meaning, ideographic-picture image with arbitrary meanings, logograph which is the units in writing representing whole delivery, syllable units represent syllables and alphabet units representing sounds that areHow language and culture connects with each other?Language and culture are connected in several other intricate and dynamic ways. The language is a product of culture and simultaneously the culture is shaped by how the language allows us to ruling it. In any kind of language things are vision other than but it must orient in a friendly manner.The priming of most inhabitants of a culture are similar because we centuries ago we ex tend to hear the same(p) stories that were said.Language connects culture in many ways, through changing the ask and trends in culture, For example words and expressions maybe compulsory to express concept that are been discovered or even been invented. These uncovering or inventions are used in everyday life. Since culture passs the way live and think while language shows the way we speak and express ourselves becomes changeable from time to time and places, for example, there are some words that described or distinguish people living in arcadian or urban vault of heavens. On the other hand some words used mean the opposite in different places both can have a positive or negative point of arrest so there particularly these happen due to changes in culture.How language interacts with context?Context is a notion used in the language science (linguistics, sociolinguistics, discourse analaysisi, pragmatics, semiotics) in cardinal different ways causely as verbal and social contextVerbal context referes to meet text or talk of an expression(word sentence conversational sour, speech act ext) influences the way we understand the expressionSocial context were defined in terms of objective social variables such as those of class gebder or race more rescently, tend to be defined interms of social indentity being construed and displayes in text and talk by languages usesLanguage interacting with context form are extremely difficult to delineate because sometimes things are hard to differentiate especially when deciding whether certain things belongs to a culture and excessively when making decisionThe context of culture is language socialization, ths merges ti the communication practices with the context of culture. Studying the language perspective is the pursuit of cultural underpinning thea give meaning to the communication interaction between expert and novice member within and cross contexts of situation.Researchers theorize about culture within different theoretical frameworks, looking culture to which includes bodies of knowledge, structures and of understanding, concepts of the world, and collective representation which are foreign to any individual and contain more information that any individual could know or learn.How words are extracted from culture?Extr acting words from culture are the most difficult to describe because culture concentrates from various aspects of human life and history.An example of words extracted from culture is tequila as that is essence of Mexico which symbolizes its culture.The other article that I had read is about the Chinese folk good example of facial expressions which was analyzed at linguistic perspective view. This research was provides how facial expression are perceived and interpreted by people in the Chinese language. Also the findings are about how facial is encoded from culture view of perceptions and conceptions of a face which are not comm further reflects in the incline languageLet me hold open about how the Mayas got their words. The Mayas spoke many languages as well and the languages are transcribed via hieroglyphs and other compose on substances. They varicoloured their words on bark paper that has disintegrated, while just two were presumed to be prestigious forms of the Maya langua ge which were said to be from southern area and one from the Yucatan peninsula,Epigraphy, which instrument writing on something, refers to writing on an changeless substance bid stone. As such, it was impressed, inscribed, or chiseled rather than written with the stylus or reed pen applied to ordinarily decaying media like paper and papyrus. Common topics of epigraphy include epitaphs, dedications, honors, laws, and magisterial registersThe Rosetta Stone, which is housed in the British Museum, is a black, possibly basalt slab with three languages on it (Greek, demotic and hieroglyphs) each saying the same thing. Because the words are translated into the other languages, the Rosetta Stone provided a key to understanding Egyptian hieroglyphsAs the origins of the Maya languages are rose in the western hemisphere from three major families, then splitted into dialects, as the time changes, the languages were changing too and became distinct. There were words, vocabulary that reflect s importance things in every culture, most of the time one word can having different meanings in different cultures.The language structure of the mayas sounds similar, while the features difference in meanings based on sounds namely pitch of vowels, glottalization of consonants, glottal stop. The history studied mention that when the Spanish positive the roman alphabet for the maya language they ignored glottal and tone distinctions. The maya language is considered to be polysynthetic referring to one complex word expressed many ideas and the word order are structured as verb-object-subject or verb subject. There is no femine and masculine pronouns but prefixes signal the genders for example naixilFew researchers like Woodbury view the purpose of languages that its linked to essential cultural content. He first described what can be transmitted and interpreted by the native speaker is more complete than if another language is used to take up the same message. For example the use o f directional in Man and other Mayan languages is a linguistic trait which conveys and decisive meanings besides the idea of direction. These speakers can communicate and comprehend the metaphorical ideas that are added to messages. Secondly he describe that if a group of people loses their native language, their cultural heritage is in like manner lost.Another example leave alone be some of the Chinese words linking to Chinese culture and beliefs. Like for example a wedding cards that are designed, it is design in a traditional that refers to good blessing, a drawing or a word written or a Chinese character ?on the card signifies blessing, unlimited fortune and happiness.Chinese characters normally have one or more meanings and some of them are particularly turn ind by Chinese people. Here is the top ten list of the massy ones.Fu Blessing, Good Fortune, Good LuckFu is one of the most popular Chinese characters used in Chinese New Year. It is a lot posted upside down on the front door of a house or an apartment. The upside down fu means good luck came since the character for upsite down in Chinese sounds the same as the character for came.Lu ProsperityIt used to mean officials salary in feudal China. Fengshui is believed to be the Chinese way to health, wealth and happiness. If you are interested in Fengshui, you may check out the book The Feng Shui Kit.Shou LongevityShou also means life, age or birthday.Xi HappinessDouble happiness is usually posted everywhere on Chinese weddings.Cai wealth, moneyChinese much say money can make a ghost turn a millstone. It is to say money in truth can do a lot of things.He harmoniousPeople harmony is an important part of Chinese culture. When you have harmonious relations with others, things depart be a lot easier for you.Ai love, affectionDont need to say any more about this one. Just motivation to point out ai is often used with mianzi together. Aimianzi means be concerned about ones face-saving.Mei beaut iful, bonnyThe United States of American is called Mei Guo in the short form. Guo means democracy so Meiguo is a good name.Ji lucky, auspicious, propitiousHope all is well.De virtue, moralDe means virtue, moral, heart, mind, and kindness, etc. It is also used in the name for Germany, i.e., De Guo.How phrases are extracted from culture?Phrases are extracted from culture that express or overdraw imagination of a reader and a listenerWhy culture and language is important?Culture is so important because these practices can continue to be passing on to generations to generation and younger generation will be able to see and read about what had existed long ago. This refers to practices of beliefs, religion, lifestyle, or traditions and festivals and this is what makes a community representing culture. Any culture represents the principle of an individuals life because it is so unique for this counts the attitudes, personality, and other behavior characteristics.While language is mai n neb used every day, be it different dialect, it still makes us survive. This is the only we can communicate or spread ideas from one to another.Therefore language make us identify ourselves of who we are and while culture describe what we do.Language and culture is so important when doing business, presently in most parts of the world things are kinda good because they interact with each other and by being successful each expanse needs to understand the different languages and most of all needs to know the ordinary background of a countrys culture. The main advantage of being able to speak another language is that it allows easy communication among each other.Therefore learn another language gives us deeper understand of the culture, gives sensitivity to have us maintain strong relationships.BiographyI am the second kidskin of Mr. and Mrs. Cresencio Cho Sr. born on September 11 in a lovely village named San Antonio Village, Toledo District, Belize.

Project Management Of The Emirates Stadium Construction Essay

Project way Of The Emirates Stadium formulation EssayA lot has been documented on the principals and methodologies required to palmyly execute a calculate, that it al close to seems a Clich when the term get off direction is discussed. However, I sh only try to focus on pop step up focal point in the wind industries as it is a salutary idea to discuss frame c atomic number 18 as it applies to a specific industry.In this deuce infract narration, I shall attempt to first captiously analyse and evaluate the PM contends as documented in the group presentations, with the aim of in particular evaluating the prudence altercates exercise set and highlighting how the groups dealt with identifying the challenges and frame trifles choose in explaining these challenges.Evaluating the procurance system adopted and considering reasons for its betrothals, benefits derived and circumstances contri scarceing to its success, before considering alternative startes.Make a simi le mingled with the get it onment strategy adopted for the emirate domain and established lift out(p) practices.THE EMIRATE troughArsenal football club had previously occupied the Highbury stadium. With a force to hold 35,000 fans, this was grossly inadequate for a club change order of magnitude in fan base imputable to her popularity and successes achieved in competition with early(a) top flight clubs in the premiership. Therefore the club way intractable to invest in a larger stadium as a means of accommodating the increasing fan population but more(prenominal) strategicalally, rebranding the club and increasing its competitiveness with top flight clubs at the premiership. bug oution OVERVIEWHence, a physical body and built contract was signed by Sir Robert alpine for a 220m worth 60,000 capacity stadium quick-wittedness, after an in cristalse formulation and conception compass point spanning 5 years. The entire start hail was estimated at 400m including relat ed looks due to relocation works and ancillary works. ( throwbuild-network.com, 2008)The actual structure commenced March 2004 and was complete by July 2006 ahead of schedule and on cypher. At the end of the entire be after, 80 transaction linees had been relocated, 2500 impertinent al-Qaedas had been provided, 2600 new jobs and 4 new community health facilities built. A successful suggest with regards to its achievement of project objectives at the stipulated time frame, at heart the estimated budget and to the quality and performance required. (Arsenal, 2007) further like all projects, jeopardizes, challenges and uncertainties be sure to abound, the outcome of the project however, impart depends on the identification and mitigations of these risks and uncertainties plus the application of wanglement strategies and tools.CLASSIFICATION AND valuation OF identify CHALLENGESSo lets verbal expression at the challenges identified, iodine identify musing from a critica l evaluatement of the group challenges identified was the frequent repeat of similar challenges expressed in divers(prenominal) words, brinyly due to varying dictions of expressions. Classification of these challenges was at that placefore infallible to critically evaluate and analyse them. whatsoever groups adopted a framework to identify the challenges. Groups 3 and 4 in particular, identified the challenges using the project life sentence cycle framework. On the former(a) hand, groups 1, 2 and 5 viewed the challenges by broadly looking at soulfulness elements of the projects strategic focus and cognitive operational stages as viewed by the decl arr during the carrying into action of the project.For groups adopting the project life cycle framework, the task of identifying key challenges was lift out viewed by considering each phase of the lifecycle. The initiation and planning stages in particular, required critical risks assessments before the performance phase becau se of the ease to adjust plans and mitigate risks at these initial phases. They in effect pointed out that, due to the attention paid to issues much(prenominal) as coaction, lymph node pluckment, extensive put investigation and a continuous assessment of uncertainties, a smooth implementation stage ensued.Presentations for group 1, 2 and 5 as key outed earlier, broadly looking at individual management strategies of the project implementation and operational stages as viewed by the declarer during the implementation of the project and can be broadly categorize under the spare-time activityStrategic Management challenges guest satisfaction, stakeholder relate and project coordination. By identifying the strike to manage people, risks, strategy adopted budgetary issues and contracts details, these presentations focused primarily on organisational elements of the project with emphasis on the pull management aspects.Operational/Design and Construction Challenges Although pro ject management challenge was the main focus, it seems illogical non to consider certain technical issues as major challenges. Therefore key engineering challenges such as restrictions in stadium height (a topical anaesthetic planning authority directive), pitch quality, service fitting and the need for rile bridges to the stadium were challenges that shaped closely decisions taken by the project managers.Table 2.1 Categorisation of Identified Challenges vigilance FRAMEWORKCATEGORISATIONIDENTIFIED CHALLENGESGROUPSPROJECT flavorCYCLE FRAMEWORKINITIATIONSScope and Specification, Identifying stakeholders, Deciding Location, Planning Business and home Relocations,3 4PLANNINGReaching and securing Authority Approval, Satisfying Stakeholder and client expectation, procural Strategy Selection.

To critically evaluate the management approach and understand the reasons for its adoption and factors aiding its successful employ, a brief description o f these two procurement approaches would be reviewed.Design and Build one contractor is engaged to design, manage and construct the project. Although mostly taking a variety of forms, the contractors roles whitethorn include the followingAs principal contractor who carries out all design and bend, with minor subcontractors.As the clients agent, managing the consultants and contractors who carry out the actual design.A combination of principal contractor for design or reflexion, and management contractor for the former(a) functions. ( F. Harrison and D. Lock, 2004)So why was this adopted? To a greater extent, it provided the client (Arsenal FC) the following advantagesTime/ contract duration could be shortened and facility ready for start of the new seasonExempted the client from the technicalities of twist a stadium. They were club managers who knew nonhing about building a stadium but recognized the importance of the facility in meeting their business goal. protected the clien t from the complexities in project organisation.Enable the client to transfer most risks identified in the conception stage.In this case study, Sir Robert Alpine was the designated design and build contractor, together with her supplying chain which included Architects HOK Sports venue, Bur Happold (the structural, windup(prenominal) and electrical engineers) and AYH PLC (Project Managers/Quantity Surveyors).Figure 2.1 ORGANISATION/PROJECT ROLE FOR THE EMIRATE STADIUM CONSTRUCTIONThe alternative, management contracting approach as recommended by all, is characterised by the client appointing an external organisation to manage and coordinate the delivery of the project. The main advantages to the client in the case study would have been benefits from time and cost savings and better flexibility with regards to changes. Thereby, allowing the client to concentrate on relations with sponsorship deals, investors and the large number of stakeholders.COMPARISION WITH BEST PRACTICEThe ma in success beat of a construction project is the care for of the facility to the client all everyplace time. Successful delivery requires an integrated process in which design, construction, operations and living are considered as a satisfying, together with an understanding of how the project allow affect efficiency and service delivery over the lifetime of the project. (OGC, 2009)So whatever they are called, outflank practices, golden rules or PM creeds, the general believe is, following these techniques summaries in figure 2.2 below willing effectively manage a project to time, cost, quality and performance. The office of Government barter therefore set out guidance to achieving excellence in construction project management. In their opinion success is guaranteed if projects are planned to arrest they possess the followingProjects provide the best option to meet the business needHave sufficient elections portiond to deliver the project and effectively manage these r esources.Are managed through specify and accepted accountabilities, supported by soak up and short reporting lines which ensure effective channels of communicating betwixt stakeholders, clients and project Implementation squadHave a clear payload throughout the integrated project team to clearly defined objectives. (OGC, 2009)I shall endeavour to compare the management approach as adopted in this case study with the recommended and prescribed best practices as stated by the office of Government Commerce.The OGC recommends that resources, roles and responsibilities for delivery should be assigned to effective individuals who are empowered to deliver, who are drawn from the business unit that owns the project.The OGC further stated, Critical consideration needs to be paid to ensuring effective lines of communication. The effectiveness of the lines of communication to top level management, who are then responsible for making decisions base on these information provided. Successfu l delivery requires an integrated process in which design, construction, operation and maintenance are considered as a whole. (OGC, 2007)Health and preventative performance during all phases of the project is mandatory. There are excessively well-grounded requirements which require clients to set requirements for healthy, safe working conditions and facilities on construction situates. (OGC, 2007)Amongst the OGCs best practice recommendations, is the filling of the respectable people for the project team. They stated that the excerption of an integrated project team is a paramount consideration in project planning. The best projects and the best clients put time into getting the right project team. They assess the quality of the individuals, their ability to work together and their experience. For the emirate stadium case study, the design and build contractor commented after the project consequence (SRM, 2009) a text adjudge example of project management and team building, Emirates Stadium showcases the benefits our collaborative approach to business can bring. Our early involvement and that of our key supply chain partners was an essential element in the projects success.Risk assessment and care for management should be continually assessed throughout a projects lifecycle. With early collaboration between the entire integrated project team, risks are better identified and resolved before risk mitigations become too expensive to implement. (OGC, 2007)The adoption of the lowest price tendered does not often lead to best shelter for money. Quality and be of the implemented projected over the life of the asset are the real indicators of value for money. The focus should always be the optimal balance of required quality and the whole-life costs of a facility the costs of acquiring it, the costs of maintaining it and the costs of operating it over the whole life of the asset to its disposal. (OGC, 2007)Judges at the awards for the building project of the year stated, The whole process was an example of how important teamwork should be to a project, with bothone from the client to the contractor and subcontractors coming together and working successfully to ensure the project was completed on time and under budget. The way that this team tackled design changes should be a lesson to the industry. (Martin Spring, 2007)In summary, the emirate stadium project highlighted in context and principle, is an model(a) addition to best practice adoption and utilization in stadium construction, of course with certain modification as best fits the project in question.Figure 2.2 BEST PRACTICE SUMMARY USING THE PROJECT LIFE CYCLE FRAMEWORKFor example, collaboration during the planning and design stage, formulating and communicating set milestones to the project team, feed backs and managing the clients expectation in view of the outcomes provided. Figure 2.3 show as weights, the management strategy adopted in relation to a summarised best pra ctice.Figure 2.3 COMPARING BEST PRACTICE WITH CASE informationTHE 2012 OLYMPIC GAMESFor this part of the report, I shall attempt to develop guidelines for the 2012 prodigious by firstlyDiscussing the differences between managing a single project and managing a project as part of a larger portfolio or programme.Review legitimate facts about the on-going 2012 majestic stadium construction that will further advert to pinpoint and discuss project management challenges.And then finally, based on the characteristics of the project identified, lessons learnt and a review of the best practices, develop guidelines for the project.PROJECT OVERVIEWIn July 2005 the International Olympic Committee awarded the city of capital of the United Kingdom the hosting rights for the 2012 Olympic Games. With the disposal of this immovable deadline, the London organising committee for the Olympic Games (LOCOG), aware of the heights of expectations, particularly after the ingenuity displayed by the Chinese, began plans in earnest. Milestones were set, plans conceived and a programme to reconstruct London in preparation for the games was hatched. The entire programme included amongst others, the renovation of a 24 hectare Olympic park to accommodate an Olympic stadium, ten sports venues, an Olympic Village, media centre, parklands, several training venues and pre-game training camps.THE OLYMPIC STADIUMThe stage was therefore set for the construction of the main Olympic arena, the 80,000 capacity Olympic stadium. At an estimated cost of 469 million, to be completed in 2011 and convertible to a 25,000 capacity stadium after the games.PROGRAMME MANAGEMENT VERSUS PROJECT MANAGEMENTHaving clearly stated how the Olympic stadium (as a project) fits into the entire Olympic delivery programme, I will begin by defining a project, a programme and their managements. This will change my arguments in reviewing the differences between managing a single project and a project under a program me of work.D.C Ferns (1991, p. 21) defined a programme as a group of projects managed in a coordinated manner in other to gain benefits which are not achievable by managing individual projects independently.R.S House (1988, p. 16) in his book the human side of project management defined a project as a group of related tasks or activities which together satisfy one or more objectives.Robert Prieto defined program management as the interpretation and desegregation of a number of projects to cause a broader, strategic business outcome to be achieved. He further argued that Programme management is not just the sum of all project management activities but also includes management of the risks, opportunities and activities that occur between projects. (PM Hut, 2008)While an individual project will employ a specific project delivery approach (design-bid-build, design/build, DBOM etc.), program management may combine different delivery approaches crossways multiple projects to best achi eve the in demand(p) strategic business objectives. In the case study as I will later explain, a consortium was formed (Team McAlpine) to deliver the project. Now using several management parameters, I will therefore itemize the differences between their managements.Table 3.1 Differences between Programme Management and project ManagementParameterProgramme ManagementProject ManagementOrganizationSemi- fixed in nature, resourced to address the full snip of business requirements associated with achievement of a strategic business objectivepassing organization in nature, resourced to address a limited set of requirements that may be more temporal in nature and not happen through all project phases.Organizational AlignmentAnalogous to building a new company with a sharply defined strategic business objective.Team alignment around project and contract requirements event DefinitionStrategic Business Outcome (enterprise viewpoint)Defined scope, schedule and budget (output viewpoint)Risk ManagementManagement of all risks associated with achievement of the defined strategic business objectivesManagement of assumed risksRequirementsEstablish programmatic and system technical requirements and allocate as appropriate to individual projectsManage project to meet the allocated programmatic and system technical requirementsInterface ManagementManagement of all programmatic interfaces between defined projects as well as other programmatic interfaces with stakeholder groupsManagement of allocated interfaces, if any, and all interfaces within the assembled project teamExecutionPlanningProgram wide exertion planning including top level schedule, budget, performance regulars, supply chain configuration and contracting strategyProject execution planning reconciled with concord to scope schedule, budget. and performance standardsTimeframeThrough achievement of strategic business objectives (more permanent in nature)Duration associated with completion of project activitiesSt akeholder EngagementIdentification and integration of stakeholders interests and proactive engagement to assure achievement of strategic business objectivesfundamental interaction with stakeholder groups only as contractually provided forSource PM Hut, 2008)Figure 3.1 impressionistic view of the London 2012 stadium.PROJECT MANAGEMENT CHALLENGESBefore outlining the challenges, we will look briefly at certain information we have gather about the games so far.The multidisciplinary management structure required to deliver the project. The LOCOG acts in the capacity of client for the stadium project. They appointed the Olympic Delivery Authority (ODA) to manage all embodied projects with the stadium inclusive. Hok sports, venues ltd was the designated architects, Bur Happlold the service engineers, Sir Robert Alpine the construction firm and M-E Engineers as the mechanical consultant. A consortium was formed and named Team McAlpine comprising all mentioned for the delivery of the proje ct.The share size and number of stakeholders was of National and world(prenominal) proportion. These includesThe mayor and people of Stratford, LondonMinister for the OlympicsBritish Olympic linkThe International Olympic committeeThe individual featured sports committeeThe division of culture, media and sportsThe British Paralympics AssociationMore than a dozen sponsors and PartnersQuite a number of official suppliers and providers.The interrelated projects that would have direct and indirect impacts on the stadium construction e.g. the Olympic park, the volodrome, the access bridges.The budget initially estimated at 280 million but quickly rose to 496 million mostly due to rising inflation and an add-on in contingencies (Guardian, 2009).The stadiums proposed location, a contaminated site at Stratford in central London. (Contract Journal, 2009)The economic downturn that hit the pecuniary market and the world in general. Rising inflation figures as released by economic analyst on the health of the economy.The announcement by the IOC, appointee sustainability as a focus for the summer Olympics, this made it clear that the London 2012 organizers had to think beyond the Olympics and consider the concept of legacy, in particular environmental sustainability. (B. Digby, 2009).Therefore, challenges were present right from the conception phase through the entire project lifecycle, and based on the facts listed above, the following challenges can be deducedThe sustainability slogan meant most of the designs proposed had to be carbon sensitive and sustainability driven. This called for innovative designs and as explained by Alan Webb (1996, p. x) the management and creation of innovative projects are the most challenging of all managerial tasks as novelty implies a leap into the unknown. It is not for the faint hearted for there are shocks and surprises around every corner.Cost and budgetary issues represents one of the superior challenges the project faces. Many things can happen during the lifecycle of a project to increase project cost estimate, distort the expected rate and magnitude of expense (D. Lock, 2007). Has was the case when the recent financial meltdown raised its ugly head.The challenge of managing stakeholder involvement is worth mentioning. Particularly regarding the sensitivity attached to stadium construction in the United Kingdom. The media was recently awash with condemnation for the management team of the Wembley stadium finishing behind schedule and with an escalated budget. Secondly, the magnitude of stakeholders warrants a worthy dissemination of information and the pre-planned mitigation of wrong or biased information. A.D. Orr (2004, P. 8) wrote, the use of a stakeholder plan is to ensure that the relationships between the principal people in the project have been discussed and the information flowing between them have been agreed.The site for the construction was reported contaminated, although this might appear not to be a project management challenge, it is important to understand the project managerial sonorousness this might generate due to uncertainties ascribed.The selection of a procurement strategy is always a challenge for projects in a multi project environment. The OGC advises that the procurement of contractor should be on the basis of whole-life value for money. The design and operation of the facility should maximize the delivery of effective service and this is most presumable to be achieved through integration of design, construction, operation and on-going maintenance (OGC, 2007). In the Olympic stadium case study, a consortium was formed and proved a substantial factor in the mitigation of the project risks.It is important to mention resources management (void of cost) as a key challenge. One of the aims spelt out in the London 2012 sustainability policy document is to demonstrate an exemplary resource management practice (TOB, 2007). As a result resource utilization wa s minimized to achieve energy and environmental sustainability and project manager had to devil tough decisions during construction.GUIDELINES FOR THE 2012 OLYMPIC STADIUMH. Kerzner (1994, p. 43) wrote, the success of a project is best determined by its ability to deliver within the specified time, cost, desired performance and technology level whilst utilizing the resources effectively and efficiently.If an organization is to be successful in the delivery of its projects, it is essential to establish standards by which those projects are selected, managed and delivered. And these standards moldiness be consistent with the organizations strategic plans (Maxs, 2009). Therefore, a step-by-step recommendation for establishing consistent successful performance for the management of the 2012 Olympic stadium can be outlined as followsPlan and understand the project lifecycle. A standard set of project phases, stages and typical milestones required by the organisations management to enabl e the consistent structuring and cost-effective processing of the organisations project. (Maxs- Issacons, 2000).Align your resources independently with each phase of the project lifecycle.Selecting a procurement strategy that best suites the project characteristics. Wright wrote, the selection of a contract and contractor are influenced by the nature of parties involve, the project objectives, and the equitable allocation of responsibilities and risk, amongst other factors. (N.J Smith, 2002)Establish a control over the project ensuring that a system of reporting, allocating responsibilities and quality assessment is well defined. spindle wrote that the purpose of control is to ensure that the projects status is reported in a consistent, cost effective and timely manner to the project manager, so that needful action can be taken. (N.J Smith, 2002)Ensure that plans are understood by all team members and constant updates of the plans are frequently done. J.P Lewis (2000) wrote, It wo uld be gracious to think that a plan, once developed, will never change. However, that is unrealistic. Unforeseen problems are almost certain to arise. The most important thing is plan, re-plan and re-plan.Continually assess risks. It is financial aidful to try to categorise the risks associated with the project both as a guide to identification, and to facilitate the selection of the most appropriate risk-management strategy. (N.J Smith, 2002)Manage the impact of stakeholder involvement in the project. Although they appear as indirect players in the project environment, the stakeholders impact on the success of the project. Therefore managing their impact is vital to every successful project.Setting delivery milestones dates for the various facets of the project and having a work breakdown structure tendings to identify critical paths and activity duration. This is a moldiness have for the Olympic stadium project.CONCLUSIONIn this report, we have categorised the project manageme nt challenges highlighted in the group presentation. In the categorisation, I have pointed out that while some groups utilized a framework for identifying the challenges, other groups mentioned the challenges under two main categories, strategic management and operational risks. In critically analysing the challenges mentioned, it would appear that selecting a framework for evaluating the risks is indeed a good practice. It is now obvious that a proper understanding of project peculiarities help to reveal challenges. While all groups were speculative about the challenges categorising the challenges would have help to further identify peculiar risks and challenges requiring the formulation of a risks management strategy.The best practice for construction management refers to tools, techniques and guidelines that have proved effective over a wide range of construction management projects. And again this report has utilized a typical project lifecycle framework to outline the necessary elements required at each phase of a project. The assessment of risk and uncertainties was a process repeated in most phases of a project lifecycle because in actual sense the entire functions of a project manage revolves around his ability to provide resolutions to those uncertainties that eventually become a challenge in the implementation of a project. The importance of planning was also emphatic at every phase of the project and planning does not take over until the project has been delivered to time, budget and quality.In the 2012 Olympic case study, differentiating the stadium construction project from a single project and identifying it as belonging to a multiply project environment reveals the need to adopt a different strategies. However, some elements of an established best practice such as value management and risk management would generally be applied successfully. To successfully Identifying the challenges, a review of the facts about the project is necessary as the magnitude and true nature of challenges become obvious. Then finally based on the characteristics of the project identified, lessons learnt and a review of the best practices, eight sets of guidelines were develop for the 2012 Olympic stadium project.

Microcontroller Based DC Motor Speed Controller

Micro ascendency Based DC Motor revive ControllerIn this report I premise a micro maneuverler found DC ride advisenonball along wangleler. DC gos down the stairstake a vital role in most of the industrial areas. They are mainly utilize for the mechanically skillful movements of physical applications much(prenominal) as media engages, indicator plants, lifts, elevators, conveyers, belt set agitates (printing press) etc.The controller implements the control dodge governing the load and aim characteristics. To match the load and move, the input to the microcontroller is manipulated by the controller. The purpose of a take fastness controller is to capture a signal representing the demanded invigorate, and to exertion the ram at that swiftness. The controller may or may non actually survey the pep pill of the beat back. If it does, it is called a Feed indorse hurrying Controller or Closed Loop Speed Controller, if not it is called an exposed Loop Speed C ontroller. Feedback speed control is better, moreover to a greater extent complicated, and may not be compulsory for a simpleton electric circuit public figure. The former(prenominal) ( stringentd loop) is implemented in the presented controller design.The subject arrangement consisted of a tachometer link up to the peter of the drive. A controller design skunknot be more accurate than methods aimed at measuring actual push speed. This is readily deliver the well-behaveds by coupling the motor shaft with a tachometer. The tachometer sidetrack signal is born-again to a dc electric potential signal unobjectionable to the microcontroller. The microcontroller is programmed to social movement the motor accomplishing the load solicitment.The operation of dc motor was studied. some(prenominal) typesetters cases of motors and various control types were investigated. The project also intends to familiarize us with the energy of flick in control organizations. To evalu ate the effectiveness of the controller, analysis withdraw from alone be conducted driving inconstant load while maintaining never-ending speed of the motor. The advantages of use microcontrollers to control dc motor were studied.INTRODUCTION1.1 forceAn electrical motor is an electromechanical finesse that converts electrical energy to mechanical energy. The mechanical energy apprise be utilise to perform work such as rotating a pump impeller, fan, b misfortunateer, driving a compressor, lifting materials etc. It is estimated that somewhat 70% of the total electrical load is accounted by motors unless.1.2 CLASSIFICATION OF MOTORS voltaic MotorsAlternating Current (AC) MotorsDirect Current (DC) MotorsSynchronousInductionThree-PhaseSingle-Phase self ExcitedSeparately ExcitedSeriesShuntCompoundFIG-1.1 mixed bag of motors1.3 AC MOTORSAn AC motor is a motor that is driven by an alter authorized. It consists of dickens basic references, an outside stationary stator havin g rollers supplied with alternating sure to pay back a rotating magnetic force heavens, and an inside rotor coil attached to the getup shaft that is given a contortion by the rotating empyrean.1.3.1 TYPES OF AC MOTORS in that respect are two types of AC motors, depending on the type of rotor utilize. The depression is the synchronous motor, which rotates exactly at the issue frequency or a sub multiple of the supply frequency. The magnetic world on the rotor is either generated by oc up-to-date delivered through slip ring or by a permanent magnet.The second type is the introduction motor, which acts s vindicatedly slower than the supply frequency. The magnetic playing area on the rotor of this motor is created by an induced current.1.3.2 TYPES OF INDUCTION MOTORSSquirrel-Cage Induction Motors The most simple and reliable of all electric motors. It is essentially a continual speed machine, which is adaptable for users under all only if the most severe head start conditions. shoots little attention as there are no commutator or slip rings, yet operates with good efficiency.Wound-Rotor (Slip Ring) Induction motor It is apply for constant speed-service requiring a heavier beginning torque than is obtainable with squirrel cage type. Because of its lower head start current, this type is frequently used instead of the squirrel-cage type in man-sizedr sizes. These motors are also used for varying-speed-service. Speed varies with this load, so that they should not be used where constant speed at each ad merelyment is required, as for machine tools.Single Phase Induction Motors This motor is used in general in small sizes, where polyphase current is not available. Characteristics are not as good as the polyphase motor and for size larger than 10 HP, the line disturbance is kindredly to be objectionable. These motors are usually used for light starting and for running loads up to 1/3 HP Capacitor and repulsion types provide greater torqu e and are built in sizes up to 10 HP.Synchronous Motors cast at constant speed fixed by frequency of the system. Require direct current for excitation and have low starting torque. For large motor-generators sets, frequency switchs, air compressors and analogous apparatus which permits starting under a light load, for which they are generally used. These motors are used with considerable advantage, particularly on large spot systems, because of their inherent ability to improve the power factor of the system.1.4 DC MOTORDirect-Current motors, as the name implies, use a direct-uni guidanceal current. A DC motor has 3 main fortunesField pole. The fundamental fundamental interaction of two magnetic sectors causes the rotation in a DC motor. The DC motor has field poles that are stationary and an armature that turns on bearings in the space mingled with the field poles. A simple DC motor has two field poles a northernmost pole and a southwestward pole. The magnetic lines of force extend crosswise the cave ining between the poles from north to south.Armature. When current goes through the armature, it becomes an electromagnet. The armature, cylindrical in shape, is linked to a drive shaft in order to drive the load. The armature rotates in the magnetic field established by the poles, until the north and south poles of the magnets convince location with attentiveness to the armature. Once this happens, the current is reversed to switch the south and north poles of the armature.Commutator. This component is found mainly in DC motors. Its purpose is to overturn the direction of the electric current in the armature. The commutator also helps in the transmission of current between the armature and the power computer address.1.4.1 OPERATION OF A DC MOTORWhen a dc motor is subject to dc potential difference, the current flows through the armature coil. A wire carrying current also has a magnetic field around it. This magnetic field distorts the check ma gnetic field of stator to produce a force which causes the armature coil to turn.FIG-1.2 operation of motorEach coil of the armature is not only connected to the brushes but the brushes are connected first to one end and then(prenominal)(prenominal) to the other end of the coil. This commutating action is demand to maintain the same direction of the current flow in the armature coils recounting to the magnetic field lines in the field poles. The motor would never turn without commutation.FIG-1.3 cross section diagram of a motor1.4.2 Types of ExcitationsThere are two basic elements in a DC motor. The way in which these are connected results in various types of DC motors.SHUNT teaseThe construction and principle of operation of a shunt motor is similar to any DC motor. This type of motor is called shunt because the field is in tally or shunts the armature. The shunt field is directly connected in parallel with the armature circuit. Shunt malarkys require large go of turns to p roduce a strong magnetic field.SERIES WOUNDIn a serial publication wound motor, the field is connected in serial with the armature. In this type, the speed tends to increase until the back EMF equals the impressed potency. The EMF also decreases the current in the field and armature. As the field weakens more speed is required to maintain the counter EMF. Thus a series motor is used only where the load is attached e.g. A lift truck, an electric crane. and so forthCOMPOUND WOUNDA compound motor has two field windings, the shunt field and series field. The shunt connected in parallel with the armature and the series field connected in series with the armature. The combination of two fields gives double advantages. It has a greater torque than the shunt motor repayable to the series field and fairly constant speed due to the series field winding. The compound motor has both shunt and series motor characteristics.These leave behind be discussed along with their control techniques in the following(a) chapter.1.5 TACHOMETERA tachometer is an instrument that measures the rotational speed of the shaft of the motor. It functions in a similar fashion as opposed to a speed indicator on a car. It tells you the speed of the car. Similarly the tachometer is used to measure the motor speed.In a fill upd loop control system the information about the instantaneous state of the getup is fed back and compared with the input and difference is used to modify the end product signal in such manner as to achieve a desired condition. Similarly a tachometer is coupled to the shaft of the motor. Thus a signal representing the speed of the motor is produced. This signal is fed back to the input where it is compared to the speed look out on potential difference. The error produced is actuated by the speed of the motor.In my designed controller the error actuating and motor control is achieved by programming the microcontroller. It is used to control the rotation of the mot or. It senses the input and process it using the program fire in it and gives the required PWM output on the required port pins. This output controls the on/off meter of the mosfet and thus controls the motor. This technique and mosfets will be discussed in the bordering chapter.As long as the speed assertion emf is held constant, the motor will run at a comparative constant speed regardless of the mechanical load. The set speed control gives a dc emf input, for example 12 volts for utmost speed and zero for stationary. This could be a potentiometer providing any electric potential in a range from zero to +12 volts. The microcontroller (PIC) amplifies the difference between the two input potential drops (tachometer and potentiometer) and the error is actuated.1.6 MICROCONTROLLER (PIC)The name PIC initially referred to chopinemable Interface Controller. Advantages of using PIC over other despotic devices for controlling the DC motor are given belowSPEEDThe execution of an training in PIC IC is very fast (in micro seconds) and can be changed by changing the oscillator frequency. One instruction generally takes 0.2 microseconds.COMPACTThe PIC IC will make the hardware circuitry compact.RISC PROCESSORThe instruction set consists of only 35 instructions.EPROM PROGRAM MEMORYProgram can be modified and rewritten very easily.INBUILT HARDWARE conductSince PIC IC has inbuilt programmable whilers, ports and interrupts, no extra hardware is needed. stiff OUTPUT PIN CONTROLOutput pins can be driven to high state, using a single instruction. The output pin can drive a load up to 25mA.INBUILT I/O PORTS EXPANSIONSThis reduces the extra ICs which are needed for port expansion and port can be expanded very easily.INTEGRATION OF OPERATIONAL FEATURES antecedent on reset and brown/out protection ensures that the run operates only when the supply potential is within specification. A watchdog fourth dimensionr resets PIC if the chip ever malfunctions and deviates f rom its normal operation.The speed of motor is directly proportional to the DC voltage applied across its terminals. Hence, if we control the voltage applied across its terminal we actually control its speed. A PWM (Pulse width Modulation) swing can be used to control the speed of the motor. Here the average voltage given or the average current flowing through the motor will change depending on the ON and OFF magazine of the quivers controlling the speed of the motor i.e. The indebtedness make pass of the wave controls motor speed. This wave is generated by the PIC..CHAPTER 2.2.1 DC SHUNT MOTORFIG -2.3Shunt windings require large depend of turns to produce a strong magnetic field.This is because a small gauge wire cannot handle heavy currents. As a result, when voltage is applied, very little current flows through the shunt coil. The interaction of the magnetic fields between the one from armature and the one from shunt coil causes the motor to rotate. The speed can be control led by varying the field strength or armature voltage. Current is supplied from the stationary housing to the rotating armature through commutator brushes arrangement. As the stator is stationary, power is applied directly to it.2.1.2 SPEED CONTROL OF A DC SHUNT MOTORThis type of motor runs at a constant speed practically, regardless of the load. It is the type generally used in commercial practice. Speed of the shunt wound motors may be change in two waysFirst, by inserting resistance in series with the armature, thus decreasing speed (FIG )And second, by inserting resistance in the field circuit. In this case the speed will vary with each change in load.This normally works with any controller setting i.e. it maintains constant speed despite variable load. Therefore, a shunt motor has proven its efficiency in adjustable speed service and loads requiring a low starting torque.2.2 DC SERIES MOTORIn a series motor, the field winding (shunt field) is connected in series with the arma ture winding (A) as shown in the figure. The field current is therefore equal to the armature current. Speed is restricted to 5000 RPMIt must be avoided to run a series motor with no load because the motor will accelerate uncontrollably.FIG-2.5V = Supply voltageE = Generated e.m.fI = Supply currentRA = Armature resistanceRF = Field resistance2.2.2 SPEED CONTROL OF A DC SERIES MOTORThe speed of a series motor depends almost entirely on the flux. The stronger the field flux, the lower the speed. Likewise, decrease in load current and therefore in field current and field flux causes an increase in speed. This can be achieved by adding a resistor in parallel with the series field winding. This causes the field current to decrease and the flux drops accordingly. This causes the motor speed to increase. The speed can be decreased by adding an external resistor in series with the armature and the field winding. This would cause a reduction in the armature supply voltage create the motor s peed to decrease.2.3 DC COMPOUND MOTORA DC compound motor is a combination of shunt and series motor. In a compound motor, the field winding (shunt field) is connected in parallel in series with the armature winding (A).For this reason this motor has a good starting torque and a stable speed.The higher the percentage of increase (i.e. percentage of field winding connected in series), the higher the starting torque this motor can handle. For example, compounding of 40-50% makes the motor suitable for hoists and cranes, but standard compound motors (12%) are not.There are 2 major types of compound motors. These are given belowCumulative compound motors first derivative compound motorsFIF-2.6 CUMULATIVE COMPOUND MOTORFIG-2.7 DIFFERENTIAL COMPOUND MOTOR2.3.2 SPEED CONTROL OF A COMPOUND MOTORThe speed of a compound motor can easily be controlled by changing the voltage supply to the motor. A solid state AC variable frequency motor drive can also be used to vary the speed of an AC moto r.2.4 PWM (PULSE WIDTH MODULATION)PWM, or Pulse largeness Modulation, is a method of controlling the amount of power to a load without having to dissipate any power in the load driver.Imagine a 10W light bulb load supplied from a bombing. In this case the battery supplies 10W of power, and the light bulb converts this 10W into light and heat. No power is lost anywhere else in the circuit. If we wanted to dim the light bulb, so it only thoughtless 5W of power, we could place a resistor in series which absorbed 5W and then the light bulb could absorb the other 5W. This would work, but the power card-playing in the resistor not only makes it get very hot, but is wasted. The battery is still supplying 10W.An alternative way is to switch the light bulb on and off very quickly so that it is only on for half of the time. Then the average power taken by the light bulb is still only 5W, and the average power supplied by the battery is only supplying 5W also. If we wanted the bulb to tak e 6W, we could leave the switch on for a little longer than the time it was off, then a little more average power will be delivered to the bulb.This on-off permutation is called PWM. The amount of power delivered to the load is proportional to the percentage of time that the load is switched on.Pulse-width modulation (PWM) or duty round variations are ordinarily used in speed control of dc motor. The duty cycle is defined as the percentage of digital high to digital low and digital high pulse-width during a PWM period. Thus by varying the pulse width, we can vary the average voltage across a DC motor and hence its speedIn my presented controller design the PWM (Pulse Width Modulation) function of PIC is used for the electric current control to drive a motor. PWM can change the duty of the pulse to output into CCP1 by the data. The duty of the pulse of CCP1 is controlled in the voltage (the control voltage). When the control voltage is higher than the pattern rank, the H level t ime of the CCP1 pulse is do long and the number of rotations of the motor is lowered. When the control voltage is lower than the regulation value, the H level time of the CCP1 pulse is made short and the number of rotations of the motor is raised. This mechanism will be discussed and elaborated in the next chapter.2.5 MOSFETSThe speed controller works by varying the average voltage sent to the motor.Imagine a light bulb with a switch. When you oddment the switch, the bulb goes on and is at full brightness, say 100 Watts. When you open the switch it goes off (0 Watts). Now if you close the switch for a dissever of a second, and then open it for the same amount of time, the filament rule have time to cool down and heat up, and you will just get an average glow of 50 Watts. This is how lamp dimmers work, and the same principle is used by speed controllers to drive a motor. When the switch is closed, the motor sees 12 Volts, and when it is open it sees 0 Volts. If the switch is open for the same amount of time as it is closed, the motor will see an average of 6 Volts, and will run more slowly accordingly.As the amount of time that the voltage is on increases compared with the amount of time that it is off, the average speed of the motor increases.This on-off switching is performed by power MOSFETs. A MOSFET (Metal-Oxide-Semiconductor Field Effect Transistor) is a device that can turn very large currents on and off under the control of a low signal level voltage2.5.1 TYPES OF MOSFETS.There are NPN type and PNP type as the semiconductor part. When no voltage is applied no electric current flows between the drain and the source.NPN type is called N-channel and PNP type is called P channel. An oxide film is put to the semiconductor of NPN or PNP and admixture is put onto it as the gate. In case of NPN, the part of N is a source pole and a drain pole. In case of PNP, the part of P is the polar side.When positive voltage is applied to the gate of the N-channel MOS FET, the electrons of N-channel of source and drain are attracted to the gate and go into the P-channel semiconductor among both. With the movement of these electrons, it conditions itself like spans a bridge for electrons between drain and source. The size of this bridge is controlled by the voltage to apply to the gate. . This type (N CHANNEL) of mosfet is used in the presented controller.FIG 2.8In case of P-channel MOS FET, the voltage is opposite but does similar operation. When negative voltage is applied to the gate of P-channel MOS FET, the holes of P-channel of source and drain are attracted to the gate and go into the N-channel semiconductor among both. With the movement of these holes, a bridge for holes is spanned and the electric current flows between drain and source.Transistor controls an output current by the input current. However, in case of FET, it controls an output current by input voltage (Electric field). The input current doesnt flow.To handle a MOS FET, needs attention because the oxidation separation film is thin. This film is prone to the high voltage of the static electrical energy and so on.CHAPTER 3The highlighted part in the figure represents the shaft which cerebrate the motor and the tachometer. The speed of the motor is directly proportional to the frequency of the tachometer. The dc voltage input is provided by the potentiometer. The microcontroller operates on a dc voltage. The output from the tachometer is a sine wave which has to be rectified in order to operate the pic. This is achieved using an F/V converter. The converter releases a dc logic signal which operates the pic.CIRCUIT EXPLANATIONThe input voltage to the main motor is controlled by a potentiometer. This variable resistor could be adjusted manually to provide a 0-12 v input. This voltage sets the number of rotations of the main motor. The input voltage of PIC becomes low when bringing VR1 close to the side 1 and PIC increases the drive electric current of the m otor. That is, the innovation of the motor rises. The input voltage of PIC becomes high when bringing VR1 close to the side 3 and PIC reduces the drive electric current of the motor. That is, the whirling of the motor slows down.Control voltage is defined as the feedback signal which is produced to recover the error between the desired and controlled speed. This is provided by the tachometer in our case.The output from the tachometer is a sine wave which cannot operate the microcontroller to perform the programmed functions. This is converted to a dc voltage signal compatible with the pic microcontroller. This changed voltage is used to enable the CCP gas of the PIC resulting in motor drive. The CCP feature will be discussed in detail later in the chapter.The control voltage to PIC is thus governed by the fluctuations of the main motor. This control voltage (feedback signal) is directly proportional to the rotational speed of the motor. The PIC microcontroller is the brain of th e circuit controlling all actions to be done and the output. PIC controls the electric drive current for the control voltage to become a regulation value.When the change of the motor slows down, i.e. control voltage goes down, the drive electric current of the motor is increased and number of rotations is raised.When the control voltage reaches a regulation value, a drive electric current at the point is held.When the number of rotations of the motor is high, i.e. the control voltage is high, the drive electric current of the motor is trim down and number of rotations is loweredD1 is used to protect PIC when the voltage of the sensing motor is high. The voltage which is applied to the terminal of PIC is a maximum of +5V. This zener diode prevents the destruction of PIC when the speed detection voltage of the motor exceeds 5V.CCP FEATURECapture, Compare and Pulse Width Modulation feature is abridge to form CCP.Capture This is the function to capture the 16 bits value of timer1 designate when an event occurs on pin RC2/CCP1. This can be used for the measuring of the period time of the signal like the frequency counter and so onCompare Generate an interrupt, or change on output pin, when Timer 1 matches a pre-set comparison valuePWM Create a re-configurable steady duty cycle square wave output at a user set frequency.The timer resource of the capture and compare is timer1 and the timer resource of PWM is timer2.The following steps should be taken when configuring the CCP staff for PWM operationSet the PWM period by writing to the PR2 register.PWM Period equals (PR2+1)*4Tosc*(timer 2 prescale value), and the resultant PWM frequency equals 1/ PWM_Period. Tosc stands for time period of the oscillations.Set the PWM duty cycle by writing to the CCPR1L register and CCP1X and CCP1Y bits of CCP1CON register.Duty Cycle is based on CCPRxL, most significant byte, and CCPxCON, least(prenominal) significant two bits. CCPRxL functions as a comparative value with tim er 2 and a scaling factor to determine the number of counts of CCPx. PWM logic remains high, without considering CCPxCON. The two least significant bits, CCPxCON, determine the percentage of the maximum resolution the PWM duty cycle is extended.Make the CCP1 pin an output by clearing the TRISC.Set the TMR2 prescale value and enable Timer2 by writing to T2CON register.Configure the CCP1 module for PWM operation.PWM can change the duty of the pulse to output into CCP1 by the data. When the time period of the H level of the pulse of CCP1 is short, the time of ON (the L level) becomes long in TR2 which implies that the drive electric current of the motor increases. Oppositely, when the H level time of the pulse of CCP1 is long, the ON time of TR2 becomes short and the drive electric current of the motor decreases.The duty of the pulse of CCP1 is controlled by the control voltage (feedback signal) which was taken in with input circuit. When the control voltage is higher than the regulat ion value, the H level time of the CCP1 pulse is made long and the number of rotations of the motor is lowered. When the control voltage is lower than the regulation value, the H level time of the CCP1 pulse is made short and the number of rotations of the motor is raised.A three terminal regulator is used for getting the operate voltage for pic. movePIC16F8733 Terminal regulator ( 7805)Transistor for MOS FET drive ( 2SC1815 )Power MOS FET ( 2SK3142 )Zener diode ( RD5A )IC socketResonatorVariable resistor for motor speed settingResistorsCapacitorsPrinted boardVFC 320 (F/V CONV)Bipolar transistor 2N222FURURE transactionDec complete circuit design and order components.January software design and circuit assemblyFebruary Simulation and preparation of final report and intromissionMarch review and appendicesApril submission.

Tragically Inane: The Cherry Orchard And Six Characters Essay -- essay

The deconstruction of the conventions of the theatre in Anton Chekhovs The Cherry Orchard predicts the to a greater extent essential obliteration presented later by Pirandello in Six Characters in seek of an Author. The seed of this attack on convention by Chekhov ar the innate dishonors of whole the personas in The Cherry Orchard. The lack of any character with which to get a line or understand creates a portrait much appressed to domain than the staged drama of Ibsen or other playwrights who came before. In recognizing the intimate flaws of its characters, we base see how Chekhov shows us that veridicality is subjective, reality is not simple, linear, or clean, and that the real benefit of theater is to show this inane, subjective reality.There atomic number 18 fundamentally trey flaws that permeate over the characters of The Cherry Orchard. The obvious first flaw is nostalgia.

Tragically Inane The Cherry Orchard And Six Characters canvass -- essay The deconstruction of the conventions of the theatre in Anton Chekhovs The Cherry Orchard predicts the more radical obliteration pr esented later by Pirandello in Six Characters in Search of an Author. The seed of this attack on convention by Chekhov are the inherent flaws of all the characters in The Cherry Orchard. The lack of any character with which to identify or understand creates a portrait much closer to reality than the staged drama of Ibsen or other playwrights who came before. In recognizing the intrinsic flaws of its characters, we can see how Chekhov shows us that reality is subjective, reality is not simple, linear, or clean, and that the real benefit of theater is to show this inane, subjective reality.There are essentially three flaws that permeate over the characters of The Cherry Orchard. The obvious first flaw is nostalgia. Madame Ranevsky is obviously the main character in this group, as she is really in charge of her family, and her inability to move on with the present is so striking in comparison with what the audience so desperately wants her to do. To her, everything is in the past - eve n the present. She cant get past the days of her childhood or the disasters six years previous. Even when she is forced to face reality - that the orchard has been sold - it seems like an event in the past. It has been inevitable from the beginning, and so even as it happens, the events are old news.

This tells the audience that the important part of The Cherry Orchard (and by extension, plays in general) is the human interaction.
