The Genius Of Shakespeare Essays (1049 words) - British Poetry

The Genius Of Shakespeare Past, Present, and Future: Finding Life Through Nature William Wordsworth poem Lines Composed a Few Miles above Tintern Abbey was included as the last item in his Lyrical Ballads. The general meaning of the poem relates to his having lost the inspiration nature provided him in childhood. Nature seems to have made Wordsworth human.The significance of the abbey is Wordsworths love of nature. Tintern Abbey representes a safe haven for Wordsworth that perhaps symbolizes a everlasting connection that man will share with its surroundings. Wordsworth would also remember it for bringing out the part of him that makes him a A worshipper of Nature (Line 153). Five different situations are suggested in Lines each divided into separate sections. The first section details the landscape around the abbey, as Wordsworth remembers it from five years ago. The second section describes the five-year lapse between visits to the abbey, during which he has thought often of his experience there. The third s ection specifies Wordsworths attempt to use nature to see inside his inner self. The fourth section shows Wordsworth exerting his efforts from the preceding stanza to the landscape, discovering and remembering the refined state of mind the abbey provided him with. In the final section, Wordsworth searches for a means by which he can carry the experiences with him and maintain himself and his love for nature. . Diamantis 2 In the first stanza, Wordsworth lets you know he is seeing the abbey for a second time by using phrases such as again I hear, again do I behold, and again I see. He describes the natural landscape as unchanged and he describes it in descending order of importance beginning with with the lofty cliffs (Line 5) dominantly overlooking the abbey. After the cliffs comes the river, , then the forests, and hedgerows of the cottages that once surrounded the abbey but have since been abandoned. After the cottages, is the vagrant hermit who sits alone in his cave, perhaps sym bolizing the effects being away from the abbey has had on Wordsworth. Wordsworth professes to sensations sweet / Felt in the blood, and felt along the heart (lines 28-29) which the memories of nature can inspire when he is lonely, just as the hermit is lonely. Wordsworth desires nature only because of his separateness, and the more isolated he feels the more he desires it. This is described in Lines : As that blessed mood, In which the burthen of the mystery, In which the heavy and the weary weight Of all this unintelligible world Is lightened:- that serene and blessed mood, In which the affections gently lead us on, Until, the breath of this corporeal frame And even the motion of our human blood Almost suspended, we are laid asleep In body, and become a living soul. (Lines38-47) In the second stanza, Wordsworth parallels his experience upon returning to Tintern Abbey five years later to his previous visit. He has changed from thinking of the present to the past. He describes using the abbey as a consolation whenever he felt overrun by the dismal, uniform, urban landscapes he had become accustomed to. However, after his first visit he began to forget the details of the abbey and what it meant to him: as gleams of half-extinguished thought, with many recollections dim and faint, and somewhat of a sad perplexity (Line 57-60) Diamantis 3 In the third stanza, Wordsworth begins a transition back to the present moment. He enjoys the pleasure of this time and also anticipates that he will enjoy it again in future memories. In the fourth stanza, however, he starts to recapitulate his life as a series of stages in the development of a relationship with nature. At first he roamed as freely as an animal, but as he grew he felt joy and rapture and passionate involvement with his own youth. Now he is involved with human concerns. He has become more thoughtful and sees nature in the light of those thoughts. He still loves nature, but in a more mature and more emotionally su bdued way. Can he salvage the meaning of the abbey and take it with him as an inspiration? In the second

The LTA group will review several aspects of the system documentation currently being used by Smith Consulting and provide proposed solutions for each of the areas defined in this document. System Analysis of Smith Consulting System Documentation Introduction Smith Consulting (Smith) has tasked LTA (Learning Team A) with developing standardized project approach and testing procedures so that prospective clients are confident that Smith is performing their contractual obligations efficiently. These procedures will be generalized so that they can be applied to any project that Smith takes on and have sufficient documentation so that the procedures are correctly applied to each project. This ensures that Smith has repeatable processes in place and can put more resources towards completing the project rather than developing the procedures to complete the project. Customer Engagement Approach Smith is dedicated to the long-term success of the project. Smith does not approach the projects as a system to be designed and left with the client to manage. Smith offers flexible management terms from support to full-time maintenance of any application Smith designs, ensuring that our dedication to service extends through the life of the product. Smith also strives to help every end-user, helping them to fully understand and embrace the new technology. Smith understands the challenges end-users face when moving to new technology, and we want every employee to be comfortable using the system. Software Development Processes and Procedures Smith realizes that there may not be one clear-cut solution for all software development projects and seeks to use a process that takes into account as many variables as possible when developing new software. This means that Smith will first need to determine the needs for the company. The first step in this process is to identify the stakeholders and develop a project timeline and budget. These factors will help drive the project toward the estimated completion date. The stakeholders will include members of Smith so that the project is kept manageable and realistic as far as time of completion and resources needed. The next step is creating an analysis team to work with the various stakeholders to understand what the company needs the new system to do. As the analysis is completed a more formalized design will be presented to the same stakeholders in the form of a data flow diagram to ensure that all the needs are being met. At this time the stakeholders will have the ability to present changes as part of the change ontrol process described as part of the Smith quality assurance processes. Smith will also implement additional design methods as required by the specific needs of a project. These methods include the use of new models, tools, and techniques in order to fully understand the system requirements. It may be necessary to bring in third-party vendors to provide and use the tools that these methods require. These vendors will be subject to a procurement process as indicated in the contract for the project and are subject to a determination of need by the stakeholders. The next step is for a finalized data flow diagram to be presented to a design team who will then analyze and determine the best approach for implementing the design. This will include determination of a tool, and the solicitation of vendors to provide the tool as needed. The stakeholders will again be consulted before any final determinations are made. Once a tool or vendor is determined the design team will work on implementing the design. The design will be implemented as part of the project plan timeline and Smith will provide developer testing in addition to end-user acceptance testing. This ensures that the final product matches the goals of the system as laid out in the project plan. Once acceptance testing is completed the system will be implemented and the system will enter its training phase as indicated in the project plan. After full implementation, the system will enter the maintenance phase. Depending on the term of the contract, Smith will be involved in the maintenance phase of the system through its live cycle. All contracts include phone support for as-designed elements of the system. Quality Assurance Processes and Procedures Smith is dedicated to providing quality of the highest level in all its services to its clients. This quality is ensured through the use of tools put in place at the beginning of the project. The most important tool in use is the project manager. All of Smith’s project managers are qualified, experienced managers who take a hands-on approach to ensuring that a project stays on the timeline and within the budget. This includes weekly updates to shareholders as well as daily stand up meetings to ensure that everyone is on track and there are no concerns to delay the project. Any concerns are immediately made known and the manager will do his or her best to provide more resources to address the problem with minimal effects to the project plan. To ensure that the project is kept within scope, a strict change control process will be used to determine what parts of the project will be able to be changed and when. This can be different for every project; Smith approaches each project plan in a similar fashion, including setting priority, and secondary goals. The stakeholders have the ability to define these goals during the analysis phase as well as a say in the change control process. Primary goals are strictly followed and changes are made to these goals only when the outcome of the project is in jeopardy. Secondary goals are more flexible and their change control process is not as severe; however the process is strictly adhered to. This adherence to the change control process ensures that the project is a success and not dependent on the success or failure of individual parts. Testing Procedures For each level of testing that takes place, Smith will develop charts detailing the testing step to be performed, an example of the chart is shown in example 1. This chart includes sections to identify what is being tested (Actor), what is being done (Action) and a description of the testing task. In addition, a secondary chart will be provided that details each step to be performed to complete the test case in question. Actor| Action| Description| Customer/Employee/Etc. | Click Button 1| Button 1 starts the applications and takes the user to the login, etc. | Customer/Employee/Etc. | Click Button 2| Button 2 logs the current user into the system| Continue†¦| | | Step| Step Expected Result| 1. Launch Application/Etc. Application window should open and prompt user for credentials, etc. | 2. Login/Etc. | User should be logged into application and appropriate menu items should be shown based on user’s security level, etc. | Continue†¦| | Figure 1 – Sample Software Capability Testing Diagrams An additional process flow that will be followed by Smith engineers is to chart the process flow for all testing for easy review by clients and engineering staff. The format of the process flow is shown in Figure 2. Figure 2 – Sample Testing Data Flow Diagram Developer Testing Smith requires its developers to perform testing on each piece of a project that they are responsible for working on. Each of these tests ensures that the software is ready for the next step in the process, whether that is integration with other pieces or implementation. The developers are required to ensure that the testing covers reliability, accuracy, fault tolerance and performance as required by the architecture design documentation for the project. Reliability Reliability testing is important to ensure that the system is capable of handling input and output in all situations it is likely to encounter during use. This includes programming for proper error handling should a user input unexpected data, as well as for handling exceptions on the data output. Developers use the architecture document to control the input and output and use exception handling to notify the user that something has gone wrong without passing the bad data along to the next process. In order to test reliability developers will purposefully input bad data and the system is required to handle it correctly. The developers are required to check not only that the errors are thrown properly, but that they are informative and the bad data are not output. Accuracy Accuracy testing is important because the input must be received, stored, transformed and output correctly. Any failure in any of these steps will affect the accuracy of the system. Developers must develop algorithms to transform the data properly so that the output is as expected. Since system algorithms can be achieved in multiple ways that achieve the same results, it is important that the accuracy is tested as often as possible. Developers are required to develop and input use cases to ensure the data are being output as required. If the output is not what is expected the developers can roubleshoot and track down the problem and run the use cases again. The system architecture document will detail the results needs, but developers often must use creativity to develop a solution to match the requirements. Accuracy testing at the developer stage is a key step for accuracy in the implemented system. Developer Performance Testing Performance testing must be performed during the development phase to ensure that the system does not have any resource or application issues prior to deliver to the customer and conforms to the stated needs of the customer. At Smith performance testing is performed during unit testing and during integration testing. With unit performance testing the developer is able to identify issues easier than during integration testing. During the integration testing phase any module interaction that was not able to be identified during unit testing will be tested. Performance testing includes the development of test cases that test each module within the client application, if resources are required such as network connectivity or file I/O then these systems will also be tested. The expected results of performance testing will be defined during the system analysis phase and will be approved by the client as acceptable criteria. Developer Fault Testing Developer fault testing is a technique used by Smith to inject errors into the software/hardware project to test the capability of the system to handle the errors in expected ways. This method of testing aids developers in the identification of the inability of the application to respond to system conditions that are expected during the normal use of the product. By using fault testing the developers can include processes that respond to these error conditions in a meaningful way. User Acceptance Reliability Like developer reliability testing, user acceptance testing for reliability is important to ensure that the system will reliably handle inputs and outputs. In UAT, test cases will be provided to selected users from the customer’s side. These test cases will allow users to test inputting information into the system so the software can demonstrate that it is capable of handling various types of input by executing on it properly. The UAT will allow the customer to provide feedback to Smith on the test cases and anything that did not perform as expected so that Smith can make any modifications to the system. In the event that Smith has to make any changes, UAT will begin again after the system has been adjusted. User Acceptance Accuracy User acceptance testing for accuracy will provide users with tests to ensure that the system is capable of handling inputs, loading, processing, storage, and outputs accurately. These tests should be consistent with the original testing that took place in the development of the algorithms to ensure that the expected results are produced by the system to the degree of accuracy that is required by the application. All calculations that the system needs to be able to perform should be tested in the UAT to demonstrate to the customer that the system is capable of handling the calculations correctly. This is the chance for the customer to fully test the system and provide any feedback to Smith. The user tests will be developed to demonstrate the full capabilities of the system. User Acceptance Fault Tolerance Once the software has been designed and implemented, the end-user’s who will utilize the software will be able to test the software’s performance (User Acceptance Testing, 2010). Allowing the end-user’s to test the software will allow IT personnel to make any changes and fix bugs that may cause future errors. All though much software may not be productive due to errors, Smith depends on test results and test reports to ensure errors are fixed and errors in the system are debugged. Below are a few tools that are used for user acceptance testing and fault tolerance: * Test Results and Error Reports User Acceptance Sign-off (Figure 3) * Production Systems * Final Installation Procedures and Instructions * Final Documentation and Training Materials * Project Plan * Methodology Compliance Form (User Acceptance Testing, 2010) (Figure 4). Smith will use these tools to ensure the User-Interface is accurate and ready for deployment. Figures 3 and 4 are sample templates fo r some of the tools used. Figure 3 – User Acceptance Sign-Off Sheet Figure 4 Methodology Compliance Form Test System Infrastructure Hardware/Software Capabilities Smith uses QuickTest Professional 10. (QuickTest) software to perform testing on all of its software projects. The software is an automated testing environment that uses testing scripts to regression test all parts of a new software product. These testing scripts are created by a developer and ensure that as new items are added, the previously tested items maintain their same functionality. Since the testing scripts are setup in a GUI environment that uses capture technology to generate them directly from the software environment that is being tested, the time required to create them is minimal and the expected results are easy to predict (HP, 2007). This ease of use helps control the testing timeline so that the projects stay on track. In addition, QuickTest provides customizable reports about errors that can include screenshots and other information to make it easier for developer to recreate the errors so they can be resolved (HP, 2007). Smith maintains separate testing hardware to handle its testing needs. This environment utilizes quad-core Intel processors running Windows Vista and equipped with maximum memory capabilities so that the testing can run as quickly as possible. The separate environment ensures that the testing can run simultaneous to the development whenever possible so that the timeline set up for any project can be strictly adhered to. Formal Program Specifications Format The format of the specifications that will be used by the software engineers at Smith will is detailed in the attachment named: System Requirements Specification. This specification includes a complete description of the requirements of the system to be built. Detailed instructions are included to aid developers in the definition of the requirements and what will be one to satisfy that requirement. Conclusion Smith Consulting takes pride in providing professional development of systems for our clients. Having the processes and requirements in place as outlined in this document such as our quality assurance processes and our developer and user acceptance testing ensures that the systems that Smith Consulting builds remain in scope with the project plan and within budget. Our processes also help to ensure that the client and key stakeholders are engaged throughout the development lifecycle. References Everett, G. D. amp; McLeod, Jr. , R. (2007). Software Testing.

The Many Uses of PBT Plastics

The Many Uses of PBT Plastics PBT, or polybutylene terephthalate, is a synthetic, semi-crystalline engineered thermoplastic with similar properties and composition to polyethylene terephthalate (PET). Its part of the polyester group of resins and shares characteristics with other thermoplastic polyesters. Its a high-performance material with high molecular weight and is often characterized as being a strong, stiff, and engineerable plastic. Color variations of PBT range from white to bright colors. Uses PBT is present in everyday life and common in electrical, electronic, and automotive components. PBT resin and PBT compound are the two types of products used in various applications. PBT compound comprises various materials that can include PBT resin, fiberglass filing, and additives, while PBT resin includes only the base resin. The material is often used in mineral or glass-filled grades. For use outdoors and where fire is a concern, additives are included to improve its UV and flammability properties. With these modifications, its possible for a PBT product to be used in numerous industrial applications. PBT resin is used to make PBT fiber as well as electronic parts, electrical parts, and auto parts. TV set accessories, motor covers, and motor brushes are examples of the uses of PBT compound. When reinforced, it can be used in switches, sockets, bobbins, and handles. The unfilled version of PBT is present in some brake cable liners and rods. When a material with high strength, good dimensional stability, resistance to various chemicals, and good insulation is needed, PBT is a preferred choice. The same is true when bearing and wear properties are determining factors. For these reasons, valves, food processing machinery components, wheels, and gears are made from PBT. Its application in food processing components is largely due to its low moisture absorption and its resistance to staining. It also doesnt absorb flavors. Advantages The major advantages of PBT are evident in its resistance to solvents and low shrinkage rate when forming. It also has good electrical resistance and because of its fast crystallization is easy to mold. It has excellent heat resistance up to 150 degrees Celcius and a melting point reaching 225 degrees Celcius. The addition of fibers enhances its mechanical and thermal properties, allowing it to withstand higher temperatures. Other notable advantages include: Excellent stain resistanceExcellent machining characteristicsHigh strengthToughnessExcellent stiffness-to-weight ratioResistance to environmental changesExcellent machining characteristicsBetter impact resistance than PETExcellent dimensional stabilityBlocks UV radiationHigh electrical insulation propertiesGood variety of grades available Disadvantages PBT has disadvantages that limit its application in some industries, including: Lower strength and rigidity than PETLower glass transition temperature than PETProne to warp when glass is used as a fillerDoesnt present satisfactory resistance to acids, bases, and hydrocarbons Future of PBT Demand for PBT has regained footing after the economic crisis in 2009 caused various industries to lower production of certain materials. With growing populations and innovations in the automotive, electrical, and electronics industries, the use of PBT will steadily increase. This is apparent in the automotive industry, given its increasing need for lighter, more resistant, low-maintenance, and cost-competitive materials. The use of engineer-grade plastics such as PBT will increase due to issues surrounding corrosion of metals and high costs to minimize that problem. Many designers looking for alternatives to metals are turning to plastic as the solution. A new grade of PBT that offers better results in laser welding has been developed, providing a new solution to welded parts. Asia-Pacific is the leader in the use of PBT, which hasnt changed even after the economic crisis.  In some Asian countries, PBT is mostly used in the electronic and electrical markets, while in North America, Japan, and Europe, PBT is mostly used in the automotive industry. Its believed that by 2020, consumption and production of PBT in Asia will considerably increase compared to Europe and the U.S. This prediction is reinforced by numerous foreign investments in the region and a need for materials at a lower production cost, which is not feasible in many Western countries.
