How to Write a Petition Letter for University Essay Example

How to Write a Petition Letter for University Paper There are different sorts of petitions that are usually written by people in order to influence decisions, change something or get something. Let us see the different forms of university petition letters. Petition for Exemption Writing petition letter for university is a very common thing. It is because there will come many instances when students have to apply for exemptions but in order to get these exemptions students first have to write a petition to the concerned person or the department. It is also important to note that it is not always necessary that your petition would acquire the approval. However, it will at least help you to make the authorities aware of you and your concerned problem. We will write a custom essay sample on How to Write a Petition Letter for University specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on How to Write a Petition Letter for University specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on How to Write a Petition Letter for University specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Prior to writing the petition to the university, it is integral to first find out the name of the department and the person in charge there. Remember that if you don’t mention the name of the person to whom the letter is addressed to, the department may avert their eyes from it. Petition for Admission Petition letters are also used when an applicant wants to take admission in a particular university. The applicants have to submit the petition along with other necessary documentation and express their reasons why they want to go for this particular program. The minimum grade to apply for admission in any academia is at least 3 GPA. However, students can still get the admission in their desired university if they tell the reason in their petition letter that why they should be taken in by the university. Petition for Financial Aid You would also have to write a petition if you need financial aid in order to continue your university study because your financial package is not sufficient. Here you have to write a persuasive petition letter to the financial aid department of that university in an effort to get sufficient aid to complete your program. You can also submit a petition again if the department has canceled the aid due to your poor grades. When writing a petition letter for acquiring financial aid it is important that you must address the justifying circumstances specifically. Briefly explain them the change in your income and expenses which are making it difficult for you to continue the studies. However if it is a petition for defending your financial aid, it is necessary to tell them If there has been an incident in your family or you were very ill during the examination. In such cases, it is also important that you must attach a pertinent document like a certificate from your physician in order to support your statement. Petition for Grades Oftentimes it is observed that mistakes are made by the teachers or professors while assessing the grades of the students. When pupils feel that they have not been given the grades they actually deserved they can file a petition for grades. Although every academia has its own method of filing a petition but the main format of writing one is the same in every college/university.

Essay on The Scarlet Letter Trial Notes

Essay on The Scarlet Letter Trial Notes Essay on The Scarlet Letter Trial Notes Scarlett Letter Trial Notes I had to watch myself slowly transform into someone I am not. The isolation given to me by the society I lived in forced me to dwell in my sins which eventually began taking a toll on my mentality and even my physical being. I had a determination to stand alone despite the opinion of society. My morals were a bigger concern to me that the thoughts of the judgmental people who surrounded me. I completely lacked any adult companionship throughout my life. The only comfort outside of my home I had was the feeling when a stranger in town didn’t comment on my past or the â€Å"A† placed on my breast. I had nothing but the strength of spirit to sustain me. One thing I have always been concerned with is trust I possess in myself and the knowledge that I am as honest as I possibly can be. Above all things, I was honest. I was not only honest to the entire public, but I was honest with myself. Even in my sham of a marriage, Chillingworth knew that I was frank with him. I felt no love, nor faked any. My life is public repentance. Even after years of social alienation I began to change again, mentally. I no long wallowed in self pity. I began offering comfort to the poor, the sick, and the broken. When the governor was dying, I was at his side. Despite the fact he never did anything to deserve my comfort. I had no friend, no companion, not one foot crossed the doorstep of my cottage. I had Pearl to raise and she produced a great number of difficulties. But in my solitude, I had a great deal of time to think. My shame in the face of public opinion, her loneliness and suffering, and her quiet acceptance of her position

Accounting Concepts Essay Example | Topics and Well Written Essays - 1500 words

Accounting Concepts - Essay Example Under the money measurement concept, these items can be recorded as a land worth $100,000, a building (containing 10 rooms and conference hall) worth $500,000, 250 chairs at $50 each, and so on The money measurement concept assumes that money is a stable unit of measurement and therefore the value of money does not change with time. Going concern concept The going concern concept implies that accounting transactions are recorded keeping the view that the business will exist for a long period of time. More precisely, a business enterprise is considered to be a going concern but not a liquidated one. As per the going concern concept, asset valuation is done at historical cost or replacement cost. The going concern concept is a fundamental principle to the preparation of financial statements (Rajasekaran 2011, p.18). In case of short term business projects like building construction, the business comes to an end once the construction of the particular building is completed. In contrast, some business entities that operate in the automobile or consumable goods industry exist for a long period and they will continue their business activities in the foreseeable future. According to this concept, business enterprises treat prepaid expenses as assets in their balance sheets even though they are not saleable practically. Dual aspect concept Dual aspect concept is one of the fundamental accounting concepts and assumes that every transaction has a two-fold aspect – giving certain benefits and receiving certain benefits. The underlying principle of the double entry system is that every debit has an equal and corresponding amount of credit (Johnston & Johnston 2006, p.54). From the accounting equation (Assets = Liabilities+Capital), it is... The object evidence concept says that all accounting activities must be objective evidence based. In other words, there should be adequate verifiable documents to support the reliability of every transaction recorded in the books of accounts. This is the very essential for auditors to verify the reliability of accounts prepared. It is to be noted that the verifiable evidences must be objective but not subjective. For instance, a business entity has to keep receipts for the building rent paid. From the above discussion, it is clear that all the ten accounting concepts explained are greatly beneficial for accountants to prepare universally comparable, understandable, reliable, and relevant set of accounts. These accounting concepts give a standard structure to books of accounts prepared globally. â€Å"The accrual concept is an accounting system which recognises revenues and expenses as they are earned or incurred, respectively, without regard to the date of receipt or payment†. In simpler words, revenue is recorded in the books of accounts on its realisation but not its actual receipt. In the same way, expenses have to be recognised when they are incurred but not when the payment is made actually. To illustrate, a business unit paid $5,000 in rent for the building and machinery a year whereas it had owed only $4,500 in rent. That means the company prepaid $500 in rent. At the end of the accounting period, the prepaid rent is recorded on the asset side of the balance sheet.

As a commander, it is therefore Carl's responsibility to conduct all pre-flight action as required of him under Article 52 of the ANO. Specifically, Carl's responsibility is to ensure before the flight that the aircraft has sufficient fuel for the intended flight. Based on the situation given, the aircraft's engine stopped due to fuel starvation, there being insufficient fuel for the intended flight. Moreover, considering Carl's failure to check the sufficiency of the fuel, he likewise failed to - (1) ensure "that the flight can safely be made," (2) take "into account the latest information available as to the route and aerodrome to be used, the weather reports and forecasts available," (3) ensure that "the equipment required" in the circumstances of the intended flight is carried and "is in a fit condition for use"; (4) see to it "that the aircraft is in every way fit for the intended flight," and (5) carry sufficient fuel for the intended flight, all in violation of Carl's duty as commander pursuant to Article 52 of the ANO. Furthermore, and as previously stated, Article 52 of the ANO requires a commander like Carl in the given situation to ensure that the flight may commence under and in accordance with the terms of a permission granted to the operator under Article 21 of the ANO, which provides as follows: "Minimum equipment requirements 21 (1) x x x.

Effective team performance Essay Example | Topics and Well Written Essays - 2750 words

Effective team performance - Essay Example In this document, this issue will be looked at critically to see how the teams in Electron were used in the recruitment process and the application of this in other organisations. This case study showed that a good team formation can be useful in creating a good platform for recruitment. Recruitment is changing, and it is getting increasingly necessary for organisations to be able to get talent and develop talents. This document will indicate, through a closer look at the facts in the case study, how an organisation can use teams in the organisation to have a proper and productive recruitment. It also indicates how these teams can be used in getting the right talents and also in maintaining the best talent and making sure that the wrong employees are kicked out of the organisation when and if necessary. 3 Team synergy A crucial effect of teams is actually synergy where each team members bring in their best and use it to improve the team in terms of productivity and efficiency (Select Knowledge Limited 2011). This document will look at this with regard to how the team members in Electron contributed to the development of a more formidable workforce. According to Dyer 2013, team synergy is about making sure that every member in the team benefits from the strengths of others and that each of the individual weaknesses are covered by the other members. However, how this is achieved can be a challenge because there may be other inhibiting factors that may make it harder for a team to synergise. 4 Team is not a collection of people One of the most important theories about a team is a collection of people with common goals and who aid each other in achieving this goal (Belbin 2012). With regard to the Electron case study, this will be investigated to see how the teams in Electron worked together in order to achieve their goals together. 5 Introduction Teamwork is one of the most important performance tools. Being able to inspire teamwork in the organisation is one of t he most useful things that an organisation can do. Teamwork may be utilised as a tool to help the organisation to overcome numerous setbacks in the market. This can be exemplified in the Electron case study. The teamwork illustrated in the case study can be looked at using the different team theories. One thing that is the most striking about the teams in Electron is that they are able to work together to a stronger force in order to achieve their goals. 6 Concertive control One of the main issues that come out in the case study is the way the team have used concertive control in making sure that the teams remain functional. There exist various factors which may be attributed to this concertive control. One of them is the fact it becomes more effective than having a manager led team. According to Kelley 1992, concertive control can be seen as a way to help the teams to be able to have leadership that is not dependent on one person but rather where everyone, new or old has a say and can contribute to the leadership. This is very useful in motivating team members into contributing to the team. People are more likely to be effective and cooperative when get the attitude that they are in control of their environment rather than when they feel that they are controlled

Adopting MapReduce and Hummingbird for Information Retrieval

Adopting MapReduce and Hummingbird for Information Retrieval Adopting MapReduce and Hummingbird for Information Retrieval in dedicated cloud Environment Dr. Piyush Gupta Chandelkar Kashinath K. Abstract: Data collected in section 3 indicated the number of active internet users across the globe. The collected chunks of information termed as Big Data not only utilizes physical resources into the network, but also leads to increase in human and financial resources. Cloud computing being a technology with IaaS (Infrastructure as a Service), PaaS (Platform as a Service) and SaaS (Software as a Service) provides virtual resources on pay per use policy. MapReduce being widely used Algorithm is used in line with Hummingbird Search engine for information retrieval. Keywords: MapReduce, SaaS, IaaS, PaaS, Hummingbird, Big data 1. Introduction One of the papers published in International conference at Jaipur, entitled â€Å"The Need and Impact of Hummingbird Algorithm on Cloud based Content Management System† [21] elaborates on existence of humming bird algorithm on 15th birthday of Google. In existence with previous Google algorithms like panda 3.5, page rank and penguin, hummingbird is a new replacement of full engine instead of repairing individual modules. This has affected 90% of data across the globe. Migrating MapReduce algorithm on cloud environment using Hadoop, not only improves performance due to cloud features but also the efficiency is increased with cost minimization. 2. Problem Fig-1: Data center Source: IBM Enterprise System Fig-1 gives a snapshot of engineers working at data centers who manages information from diverse platforms and resources. Managing hardware and Network with virtualized resources needs dedicated young talent. When it comes to end user, he gets an average service as a result of improper management of data centers. MapReduce is one of the best known algorithms used for IR (Information Retrieval) in addition with existing algorithms as explained in section 7. Due to exponential increase in smart devices that supports voice based search, definitely needs fast and efficient searching algorithm for information retrieval. The voice based search assists to make smart decisions in real time applications like place identification, weather forecast and medical assistance using android based applications. 3. Why problem is important Fig-2: Global Internet users Source: W3 Foundation Looking at data increase across the globe as shown in Fig-2 (data collected till July 1, 2014) [19], the pilled content in repositories is increasing worldwide. It requires huge amount of hardware resources running for years to extract information and knowledge for decision making. The big challenge in big data is ever increasing content utilizing human resource and cost to create chunks in available networks across the globe, which needs attention. 4. It is an unsolved problem From the following relevant reviewed literature (table-1), it gives a blueprint that the problem has still remained unsolved. The authors have either focused on cloud components [6] [11] or had used traditional Google Components during the analysis. Since Hummingbird Algorithm [10] is not keyword based the searching criteria have changed. When combined with MapReduce [1] [3] [15] in cloud environment shall definitely yield efficient results with minimum cost and resources. Table-1: Existing Systems compared 5. Here is my idea Fig-3: Proposed Information Retrieval System Being cloud computing [4] [6] is upcoming Technology as discussed in section -7.2, is a good source of virtualized resources that helps to manage content on diverse platform irrespective of geographical boundaries. An instance of Hadoop that supports MapReduce Algorithm (elaborated in sec-7) is migrated in cloud environment using SaaS (Software as a Service) to whom input is diverted for processing. Hummingbird (more in section-7) Algorithm is a brand new search engine designed to understand meaning from acquired query instead of word, is imparted to collect output from MapReduce instance. The collected output on Amazon S3 cluster is efficiently and effectively delivered to end user based on voice based request, in addition to traditional systems for efficient decision making in the field of medicine, scientific research and so on. 6. My idea works To confirm the working of proposed idea, a hosted instance of Hadoop was used that supports MapReduce Algorithm and S3 data cluster from Amazon. It also has Qubole [20] managed database to test the instance in cloud environment. Qubole has an API (Application programming Interface) that gives overview of running instances through dashboard. A user shall give input as a database or can manually select file in addition to query wizard. Once the input is given to MapReduce cluster, data analysis shall be done by using hive query in addition to pig script. Following results were collected by using existing database. Fig-4: Cloud based Hadoop Instance Source: Qubole Figure -4 shows a dashboard running Hadoop instance, in which 2 queries have finished data analysis. It communicates at runtime with Amazon S3 bucket where data is stored for input. The mapper [1][3][15] scans the data files from the source and extends the output to reducer. The reducer further processes data and is sent back to S3 cluster for further processing. This information shall be accessed by end user through web access and with the support of Hummingbird Algorithm. Fig-5: Running Hadoop Cluster Source: Qubole Fig-5 shows a single running Hadoop Instance in cloud environment. Qubole supports metrics of instances running simultaneously that enhances performance their by increasing efficiency. The graph in the above figure indicates time spent to complete single job. Every task is monitored by master DNS having unique ID. To each DNS a list of queries shall be given as input for further analysis. Fig-6 shows process getting started on Hadoop Cluster that combines both map and Reduce session together. The jobs performed uses batch processing system for single instance. Running multiple instances on different clusters in cloud environment makes process more efficient without investing much is physical infrastructure. As a result of which end user shall enjoy the benefits of information retrieval with minimum time, cost and physical resources. As cloud supports pay per use policies resource allocation as per requirements becomes easier. Fig-6: Hadoop Master DNS Source: Qubole Detail explanation about concepts existing algorithms used for information retrieval BFS(Bredth First Search) Redundant BFS. ISN (Intelligent Search Machine) Directed BFS Random walker search Randomized Gossiping Centralized approach Distributed Information retrieval Searching Object identifier Following explanations shall help to elaborate more about specific areas. 7.2 Cloud Architecture Fig-7: Cloud Architecture Source: NIST Cloud is an upcoming technology that supports IaaS (Infrastructure as a Service) PaaS (Platform as a Service) and SaaS (Software as a Service) as shown in Fig-7. For any hosted instance in cloud, open source software is used as a server that supports virtualization and Grid technology. Virtual private network is used in addition to broadband network13] [16]. As a service provider SLA (Service level Agreement) is signed between an organization and service provider. Distributed computing is one of the known components as data transferred across the network requires secure, authentic and efficient service in a given network. The type of cloud includes public, private, community and hybrid cloud [2]. Private clouds are hosted in dedicated environment having firewall and other authentication features. Updating existing system and taking backup remains responsibility of the owner. Hybrid clouds may be hosted in private environment in synchronization with public resources. The end user held responsible for resources used in public cloud with minimum security. 7.3 MapReduce Algorithm Fig-8: MapReduce Algorithm Source: Jimmy Lin, University of Maryland The algorithm takes data input as a file or database in the form of query. A list of mapper instances are activated which travels across the database in search of information. The jobs or data values are shuffled based on keys and aggregated as an input to reducers. These reducers understand the key inputs and reshuffle to get unique relevant information for further processing as shown in Fig-8[1]. 7.4 Hummingbird Algorithm Hummingbird Algorithm [10] [21] is the latest birthday gift from Google. Panda 3.5 and penguin were basically filters applied to searching criteria in the form of web pages and hyperlink. The traditional search engine extracts information based on keywords. Considering a sentence â€Å"How many times does hummingbird flap their wings per second?† the traditional search engine being keyword based tries to extract word like times, flap and per second. Based on collected keywords the web pages are searched in database. The collected content undergoes filtering from panda and penguin. Resultant results are displayed to user in the form of hyperlinks. Being hummingbird is innovation in the field of search and meant for voice based information retrieval, it accepts query as a single sentence instead of keywords. The engine tries to understand meaning and creates knowledge base from provided information or query. Fig-9: Hummingbird Search Source: Google.com In fig-9, the query asked to Google was where am i? Using voice search. The search engine had found my current location based on IP address or physical location and displayed map for the same. 8. Conclusion and future work The paper is continuation to hummingbird Algorithm [21] that supports MapReduce Algorithm with Hummingbird search engine in dedicated cloud environment. Qubole a hosted Hadoop instance is used to confirm working of MapReduce in support with Amazon S3 for data during. A single hive query instance on single DNS is tested which shall be extended for testing multiple instances of hive and pig script simultaneously as future work.

Deforestation Essay -- essays research papers

Deforestation   Ã‚  Ã‚  Ã‚  Ã‚  The planet Earth is being scarred. Everyday the people of the planet earth are polluting the planet’s air, water and land. These are all natural resources that are necessary for our survival on this planet. Yet, we continue to abuse our planet. Our world population is growing out of control. The simple lesson of supply and demand tells us that we will need more resources in order to support the booming population. One of the most important factors in survival is food supply. With out enough food, we will not survive. Unfortunately, our forest ecosystems are paying the price for the food demand. Deforestation is a major problem on our planet. It is something that must be carefully monitored and regulated.   Ã‚  Ã‚  Ã‚  Ã‚  Deforestation is a practice that has been taking place for thousands of years. Human beings have found it necessary to clear out the forests for settlement and cropland. Although there is no evidence as to how much of the planet’s forests has been cut down, it is obvious that this valuable ecosystem is declining. Studies estimate that, â€Å"original forest cover has been reduced by nearly 50 percent.† (WRI, p.90)   Ã‚  Ã‚  Ã‚  Ã‚  The forest ecosystem provides a number of services both directly and indirectly to humans. For example, the Carbon and Nitrogen cycles are two of the cycles that are necessary for survival on our planet. Carbon is a key element on our planet. Carbon is found in the atmosphere, in plants and animals and in the ocean. â€Å"About 33 percent of the carbon that has accumulated in the atmosphere over the past 150 years has come from deforestation and changes in land use.† (WRI, p.50) When the carbon is in plants, it is released back into the atmosphere in a process called cellular respiration. If the trees and plants are cut down, the carbon cycle is not completed. The carbon will not be effectively removed from the air. â€Å"Fifteen tons of carbon (in the form of carbon dioxide) occur in the air column above each hectare (2.5 acres) of the Earth’s surface. One hectare of lush vegetation can remove 50 tons of carbon from the atmosphere annually.† (WRI, p. 60)   Ã‚  Ã‚  Ã‚  Ã‚  Nitrogen is another key element. Lack of Nitrogen could limit plant growth. Often times, Nitrogen is added to fertilizers to help increase the growth of the crop. However, beca... ...restrictions on any practice, which could have a physical effect on the environment. For example, the government should have a good inventory of the country’s natural resources.   Ã‚  Ã‚  Ã‚  Ã‚  The government could also attach taxes to any natural resources, which are being traded out of the country. These taxes could be used, for example, to help replant forests. The money would help encourage farmers and timber harvesters to use alternative means in order to help protect the forests. Conclusion   Ã‚  Ã‚  Ã‚  Ã‚  We have learned in class a lot about environmental sustainability. Humans are just a part of the many ecosystems on our planet. It is important that people consider themselves equals to the other species on this planet. We need each other in order to survive. Increased croplands may be a necessity, however, there are ways to make it less damaging to our environment. We cannot always look at the quickest, cheapest ways to get what we need. In the end, if we don’t change our ways, we (humans) will be responsible for the ultimate demise of our planet.   Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚     Ã‚  Ã‚  Ã‚  Ã‚   Deforestation Essay -- essays research papers Deforestation   Ã‚  Ã‚  Ã‚  Ã‚  The planet Earth is being scarred.
