Earth and Space Science - Assignment Example The moon, bombarded by millions of meteorites and asteroids, is where Neil Armstrong's still tangible footprints are said to survive perhaps a million more years in the absence of air to change their form. Farther out, a traveler's curiosity is taken to an acquaintance with the planet named after the goddess of love and beauty for bearing a splendor as the solar system's brightest. Indeed the spectacular yellow clouds reflect the sunlight and the size and gravity of Venus is near that of the Earth's but the dazzling clouds are actually made of sulfuric acid and its atmosphere a noxious carbon-dioxide-concentrated air. With an unbearable pressure and temperature approaching 500Â °C, an experience of staying in it is nowhere as lonely as it is seen from afar or from an illusion which, once broken by reality, entails corrosion, suffocation, and destruction of a living matter. The possibility of life also becomes amply questionable at the sight of a global image, sun-scorched to 400Â ° C by midday yet acquires an extreme end of -170Â °C at nighttime. ... With over 5,000Â °C of hotness at the surface able to launch a nuclear reaction and tens of millions of degrees down its core, the Sun's power is far more than could possibly enter a wild pondering, as it turns millions of tons of matter into energy every second exceeding that made by man and blasting severe radiation onto the outer space through the electrified incandescent gases. Comets, being the documentary's additional exhibit, are depicted to be icy wastes of deep space whose tails extend to millions of kilometers. At a closer look, audience sees a vast dirty snowball covered in tar from which grains of an organic-looking parts disintegrate gradually. Much as the comets had been discovered of certain properties besides preservation in ice, the quest of astronauts and scientists has gone about prospecting Mars for any signs of life. Mars, a red and dead planet, looks as if it were a giant fossil with twirling devilish dusts presumably larger than the largest tornado that ever o ccurred on Earth. Though it is somewhat real close to capturing human imagination of familiarity and probable living, Mars is proven to contain too thin an air for breathing with significant levels of hazards caused by carbon dioxide everywhere. In it there is nothing to shield humans from the Sun's UV rays unlike the layer of ozone on this planet and protection against sickening coldness of -80Â °C neither exists. The dead planet, nevertheless, may be claimed to take pride in its immense ancient volcano that is three times the altitude of Mt. Everest and the seemingly 'grand canyon' land form which must have had some geological activities as evidenced with the way it looks in the presentation aided by the special apparatus in space.

Belonging Speech Essay Example for Free

Belonging Speech Essay This is reflected through the anthology, â€Å"Immigrant chronicle† written by the Australian-Polish poet, Peter Skrzynecki. Through his knowledge but mainly his own experiences, Skrzynecki conveys the difficulties of belonging, not belonging and the barriers which prevent belonging. He has shown us how valuable a sense of belonging is to a foreigner, as it can emotionally alienate you from your family as w ell as battling to keep up with the forever changing society, famously remembered in the poem ‘Feliks Skrzynecki’. Similarly, in the dystopian novel â€Å"A clockwork orange† written by the English author Anthony Burgess, Alex is a criminal who doesn’t belong anywhere within society. Moreover, the two thousand and three children’s Pixar film â€Å"Finding Nemo† directed by the American, Andrew Stanton, shows the emotional discomfort of the protagonist, Nemo when he is captured and fretful Marlin as he incautiously journeys through the unknown waters to find his son. As we’ve noticed the notions of belonging and what it can provide us emotionally, the eulogy ‘Feliks Skrzynecki’ depicts the dissatisfaction of not belonging. Although the very first line of the poem, â€Å"my gentle father† shows a sign of acceptance and admiration of his father, Skrzynecki’s overall statement shows resentment, dissatisfaction and alienation, â€Å"Watched me pegging my tents further and further south of Hadrians Wall†, Hadrians Wall used as a symbol comparing the differences of his culture and heritage with his father. Likewise the poem ’Migrant hostel’ was written in Parkes, 1949-51, which happened to be during the time of ‘White Australia’ policy. The fact Skrzynecki wrote this poem in ‘Parkes’ he was only further alienating him from where he is and it creates a barrier to society which can damage him emotionally. The first stanza Skrzynecki expresses isolation, dehumanisation, uncertainty and curiosity. That was the environment Skrzynecki lived in for two years. â€Å"Like a homing pigeon† Skrzynecki lived in the chaotic hostel crossing paths with the people he shared a room with. The hostel became a place for everyone to rest which formed a sense of belonging as the reason why they are there together was driven â€Å"By memories of hunger and hate†. To belong is to form a connection which will allow a sense of identity, without this we inevitably lose our humanity, individuality, and the sense of freedom. This notion is elaborated within the novel, A Clockwork Orange, where the government attempts to suppress his criminality by physically preventing him from thinking of violence, making him conform to their standards. Equally, this conception is portrayed in the poem, ‘St Patricks College’. St Patricks College referred to as a microcosm of Alex’s futuristic city of London. Skrzynecki’s ironic imagery of â€Å"Our lady watched with outstretched arms, her face covered with clouds† and later our lady still â€Å"watching above unchanged by 8 years weather† not only questions the stability of concrete statues but imitates the similar involvements of Alex and the governments projects. This restricts Skrzyneckis potential to find a sense of identity as he is held in by Mother Mary with â€Å"outstretched arms†. Similarly, Alex unknowingly got brainwashed and lost his identity, resulting with Alex revolving into a ‘Clockwork Orange’. The loss of identity and individuality in both the novel and poem reinforces the impact a sense of not belonging can have on any human being. Finding Nemo is a complete portrayal of belonging and the fulfilment of emotional needs. The movie started off with a long shot, the whole scene capturing a sense of familial belonging between mother and father, very touchy, whilst looking lovingly over their eggs. After the incident with the barracuda, Marlin’s been scarred for life and becomes obsessed with protecting his surviving son Nemo from physical danger, immediately forming a sense of unity. Similarly, a dark and foreboding representation of a blockage for Marlin, the fish on the rock perhaps a symbol for his fears of what happened to Nemo. This representation is strengthened by the distant camera shot reflecting on Marlins detached connection with Nemo. A mixture of the notion of belonging and the act of over protection may lead to major conflicts and disagreements as the connections with whom you belong to continues to progress. This may result in defiance and the consequence can be much more unexpected than usual. Likewise, when Marlin appears and distrustfully gets in Nemos face or even approaching open water, he insults his son by once again denigrating Nemo’s swimming abilities. Nemo defiantly swims out to the â€Å"butt† and promptly slaps his fin on the boat after he’s been told by his father â€Å"If you put one fin on that boat†¦Ã¢â‚¬ . Nemo soon after realises his rebellious act was yet to be paid for as he get scooped up by a scuba diver and placed in a dentist’s fish tank. When Nemo and Marlin reunited, Marlin is given a second chance at parenthood. He allows more space, freedom, trust and respect, in return Marlin receives Nemo’s trust, forgiveness and love. We have noticed how a sense of belonging can fulfil such deep emotions, along with the ability of curing a damaged connection. Ultimately, a method to fulfil ones emotional needs can be achieved through a sense of belonging. This is shown in the anthology, â€Å"Immigrant Chronicle† written by Peter Skrzynecki, which highlights the significance of belonging. Likewise, the text â€Å"Clockwork Orange† written by Anthony Burgess depicts similar aspects of not belonging. Finally, the Pixar film â€Å"Finding Nemo† directed by Andrew Stanton portrays the different a possibilities that may come with defiance of experience, trust and belonging.

Waterfall Model Vs Prototyping Model

Waterfall Model Vs Prototyping Model Software products developed in todays era are mostly customer oriented. It is either drives the market or it driver by market. Customer Satisfaction was the main aim in the 1980s. Customer Delight is todays logo. Market needs more customers oriented and less emphasizes on the technology. Though the technology factor is always the prime factor behind the deliverables, the product should always satisfy the customer needs. The product development should start focusing on the customer requirements in case of both the retail based products and products developed based on pre-defined specifications. The software products like other engineering products have various types of development or manufacturing strategies to obtain the final output. The most famous software development strategies are as follows: Waterfall Model Evolutionary Model or Prototyping Model Incremental Model Spiral Model The most used models are Waterfall models used for generally small scale projects and single release based software products, whereas the Prototyping Model is used for developing large scale products generally developed in multiple parts rather than single release also called version of release. The software developments strategy I prefer is Prototyping Model. The reason for selecting the Prototyping Model encourages progressive strategic development with course of time. With prototyping model, I am also using non-agile approach and USDP methodology as active part of the development process. The usage of the prototyping non-agile approach and USDP methodology is justified below to be the best choice for my Project. WATERFALL MODEL vs. PROTOTYPING MODEL Waterfall Model is a flow based model which consist of following phases:- 1. System/Information Engineering and Modeling 2. Software Requirements Analysis 3. Systems Analysis and Design 4. Code Generation 5. Testing 6. Maintenance A Waterfall method of software development has to pass through every phase once, and not meant to go back to previous phase again. Once the requirements request made freeze, changes cant be done during any phase. That is why, it is used rarely now a days. Due to this If there is any change in requirements, and then it becomes difficult as well as costly affair. Apart from this each phase takes a lot of time to produce solution for its consecutive next phase as it is irreversible process the solution should be well optimized and satisfactory. If one phase result goes wrong means subsequent phases get effected. Prototyping Model is a technique that uses the technique of replication of few aspects or feature of expected product and it is then developed upon it to obtain the full software. It can be called designing of software prototypes or temporary versions of software program being developed for full edition deliverables. The main theme behind the prototyping is to allow users to evaluate developers proposal for the design of expected product based on real time analysis by user rather than interpreting by the developers themselves. So it is also referred as an efficient way of controlling the prototype that act as a key factor in the commercial relationship between clients and respective solution provider. The client and the contractor can compare if the software made matches the software specification, according to which the software program is built. In Prototype strategy of development as we create a number of Prototypes of the product, before the release of final one. We release number of Prototypes with some differences between them just as versions, and take client opinion, and modify the final Product, as per client suggestions. Prototype is developed by keeping currently known requirements in the mind. Development of prototype undergoes design, coding, testing like phases which give client an actual feel of the system. Prototype is a model which looks exactly like Software development life cycle (SDLC). AGILE MODELvs NON-AGILE MODEL Agile software development is mainly based on iterative development in which solutions are generated from the collaboration between the phases and functional teams of development. The agile software development approach has taken the software developing industry by storm. Agile software development has been en vogue in this decade. It started with the popularity of Extreme Programming (XP) and Kent Becks series of books on the topic. Somewhere it creates a misleading impression that agile is not formal and hence maintenance cost is reduced or controlled by spending more on up-front design. Of course, traditional (non-agile) methods shine in other areas. Agile methods are counter indicated, for example, where there are no system experts, so that only exhaustive study can possibly reveal whats truly needed. Most agile methods are, of course, informal, and so will not work unaltered in a problem area where formality is one of the requirements; but enough agile methods have been formally documented that for any formal project where exhaustive study is NOT a requirement, there should be precedent for using a (formal) agile method. Non-Agile software development provides a traditional simple way to develop software. It reduces the whole cost as well as time consumed in the development. It is less affected from the type of resources. Management information system (MIS) A management information system (MIS) is a process that provides the information which are essential to run an organization professionally. MIS are totally different from regular information systems in that they are used to analyze other information systems applied in operational activities in the organization. Academically, the term is commonly used to refer to the group of information management methods tied to the automation or support of human decision making. MIS are computer-based system that provides managers with the tools for organizing, evaluating and efficiently running their departments. In order to provide past, present and prediction information, an MIS can include software that helps in decision making, data resources such as databases, the hardware resources of a system, decision support systems, people management and project management applications, and any computerized processes that enable the department to run efficiently. MIS are designed for ease of any type of business or organization. Now almost every kind of organization has its own MIS. It is a suite of software applications that together make it possible for people or businesses to store, modify, and extract information from a database. There are many MIS places in your everyday life like in banks, hospitals, hotels; colleges and universities have their own management system. MIS are helpful for organizations and institutes. Universities have their own managements systems. There are many departments in a university like examination, admission, registration, administration, hostel, finance. All these are required a proper and complete management, so for this reason MIS are designed to manage these departments. Every department has its own MIS which is specifically designed to handle its operation like data retrieval, storage and modification. Whenever the internet came every organization and institute is try to provide the better facilities through making their MIS online to satisfy their client. Todays every company and organization is moving on internet and building database in such a way that provided the better facilities and interaction to their clients as compare to past. Library information system (LIS) LIS are designed to record and maintain the information related books and activities of library. LIS plays unavoidable role in a university library because it provides the information about all types of books in a better organized manner. LIS keeps the track of all the books in a university. It contains records of each and every book and the members who borrowed the book. In other aspects LIS also serves as an accounts manager for library. It tracks and calculates possible fines, takes care for member securities and when required provide monetary calculation related to library to the university accounts office which manages university financial resources. The LIS is always ready to share data with the university central accounting system [1]. Traditionally manual file based systems serve as LIS in universities. Registers and note books are used to maintain records for available and borrowed books. A university having multiple departments normally has requirement to maintain a separate register for each department and sometimes for each session a department may demand to have a separate register. This builds a large register set which is very difficult to maintain and is highly error prone. In such scenarios to issue book needs much effort whereas at the same time to calculate and report monetary issues, and perform other managerial tasks may sometimes take days or even weeks. The library user pool is mainly the students and the university staff. Library cards are issued to each of them. When Students or staff members borrow books from library, the librarian needs to search for the relevant register and enter the information of borrower and the borrowed book on relevant page. At the same time he needs to assure that the member should be clear from library issues, the book can be borrowed and it is also his responsibility to provide the member with his time to possess the book. Sometimes members are not known to timings or forget to return the book in time even when they want to return it. In manual management of LIS it is not possible to regulate to process of warnings for library members when their returning dates are near to come. On the very other side where student are staff also feel very difficult to integrate with such system because the most irritating part of this system for them is the time took on any process, either to borrow book or to search book or most irritating when they need their clearance from the library and it take a day to just get a single signature. The only solution to these drawbacks of manual LIS lies in automation of the library information system by computerizing it and integrating with other management systems of a university. By automation of LIS it means to develop a fully computerized system that serves to enable the complete library operations through computers. Automations have some traditional advantages over manual systems like no paper work required and easy to backup, higher consistency of data and it is possible to schedule those tasks which are somewhat impossible in manual systems. Similarly, in context of LIS automation results in ease of library administration, control and tracking processes. The convenience of both librarians and members who use library is increased due to higher decrease of time. It becomes a matter of minutes to perform managerial tasks and estimating monetary matters and many other issues which are never resolved in manual systems. It all becomes wonderful when automation also occurs in making the system online, because through this the system becomes available for 24 hours 7 days a week. It means the student has no need to go through so many book racks to find a book and does not need to go to library to reserve a book. He just needs to go there and get his reserved book. He must not be worried to remember the returning date because he knows that he will be sent an alert indicating the return date of the book he has borrowed. So all this becomes more and more convenient with the increased automation in the process of LIS. LIS Automation for university means to develop a fully computerized system that enables the complete library functions through computers. The system provides the basic set of features to add/update/delete member, add/update/ delete books, search for books, and manage check-in / checkout processes. Automated LIS is designed to meet the needs of libraries both large and small, not only to meet the traditional requirements of a resource centre, but also able to keep track on borrowed books in university. This system is very helpful for university staff, student members and librarians because this system is also interact with the bar code reader and magnetic card reader. When the student and staff members are registered in university they are issued library cards from library. Through this card they can borrow books from the library. When they enter in library their cards are identified through the magnetic card reader and barcode reader is helpful for them in searching the books. The automation of LIS lessens human efforts in university. The maintenance of the records is made efficient, as all the records are stored in the database, through which data can be update, delete and retrieved easily. It also reduced the chance of frauds and errors because all things are computerized. Existing solution EXISTING SYSTEM ARCHITECTURE The existing LIS in university is completely manual and file based. It contains the records of all books and members of the university so this builds a large register set which is very difficult to maintain. In this situation to issue book, return book, fine management, catalog management and member registration verification need much effort whereas at the same time to perform other managerial tasks may sometimes take days or even weeks. C:Documents and SettingsATIFADesktopuntitled.JPG Figure 1: Manual Library System In this system, it is also very difficult to control the process of warnings for library members (student and staff) when their returning dates are near to come. Student and staff members are also faced the problem of book search and borrow. And when they need their clearance from the library, it also takes a day to just get a single signature. In existing manual system all the library members (librarian, staff and students) are faced a lot of difficulties when they are going to issue book, return book, fine management, book catalog management and member registration verification. Issue Book To issue a book in an existing system is a big matter because when student and staff members borrow books from library, the librarian needs to search for the relevant register and enter the information of borrower and the borrowed book on relevant page. At the same time the book can be borrowed when librarian is assured that the member should be clear from library issues. Return Book To return a book process is also very irritating and time consuming as well as the issue book process. Sometimes members are not known to timings or forget to return the book in time even when they want to return it. In this system it is not possible to regulate the process of warnings for library members when their returning dates are near to come because this system is completely manual. Fine Management Because the existing LIS in university is completely manual so the fine management is also a tuff and time consuming task. It is very complicated to tracks and calculates possible fines, takes care for member securities and when required provide monetary calculation related to library to the university accounts office which manages university financial resources. Book Catalog Management University central library contains the records of all books related to its every department and its LIS is manual so the book catalog management is not easy. When members returned the borrowed books then there is no proper management to see is the book is placed at right location or not. To add, delete and search the required book is time consuming process because librarian needs to arrange the proper registers for this. Member Registration Files and registers are used in university for member registration, so that all the student and staff members records are saved on them. When the members information are added, deleted and updated the entries in associated registers are also updated which required a large amount of time. Student and staff members registration information is also required to LIS to issue the library cards of each of them. Library staff adds all these information in registers to keep the track of members of LIS so this is also required enough time. The complete functions of existing system are shown in figure. It represents the overall functionality of library in university. Proposed System Architecture Scope of Proposed System Library System is a library information and knowledge management system. This application is used to support a librarian in managing a book library in university. The system is designed to provide the basic set of to add, delete or update members, add, delete or update books, and search for books processes. The main focus of this system is to reduce human efforts. The maintenance of the records is made efficient, as all the records are stored in the database, through which data can be retrieved easily. Some of the other specific objectives of the Library System are as following: Minimum amount of work should be required. Special hardware such as bar code reader and magnetic card reader should be used with this system for security and efficiency. Permanent storage of data should be done easily by using the database instead of the registers. It provides the interface for librarians to interact with the backend library database. It provides the interface to add, delete or update new student and staff member in the database. It also provides the interface to add, delete or update book information in the book database. GUI to search for a book based on user inputs. It provides the interface to check out of books which are issued by student and staff member. It also checks in the books which are returned by student and staff member. Calculate and manage the record for fine. Provide a facility to automatically send reminders to university members when required. Product Perspective The Library System is developed for the library to help the staff members, students and Librarians to search and borrow books. The system provides information related to books to the members of the library. The Librarian can keep the tracks of books updated all the time so that the student and the staff members get the up to date information all the time. This system is developed to interact with its users like librarian students and staff members of the university. The system has to interact with other systems like: Library System, Member Registration System, Catalog Management System, Accounting System, Email System, Fine and Reminder Bot System, Purchase Management System, and Online Client System of university. Software Requirment specifications Introduction The library system provides the information about the books available in the Library. It provides different type of services for its users, such as reserve book, renew book, check items, and check fines and view hold requests in the account. The following requirements specifications and required functions of the Library System are given below: Library members The Library has university staff and students as its members. All members must be registered with the library and issued with Username and Password for accessing their account in Library System. Book issue and return When a library member login via his account he can issue books. The system restricts the borrow limits as this a staff member can borrow up to 4 books up to 4 weeks and a student can borrow up to 2 books for up to 2 weeks. When a book is borrowed or returned by the library member, the information should be captured in the system and the account of the member should be updated. Only book items can be issued in library, currently journals and magazines should only be read in the library. Fine calculation and send late book reminders The system is able to calculate fines and send reminders to members automatically. When a return date is overdue, information about overdue items, overdue days and accumulated fines is sent to the user via email. Adding and deleting books Librarian is responsible to maintain the information about catalogues and library members. He can add, update and delete books in database. Querying to find books The system provides search functions to library members they can search a book through online catalogue. All book items in library are searched either by ISBN No or Author. Report generation Library system generates reports for the system administration automatically. User characteristics The main users of the system are student and staff members, librarian of the university who maintain the system. It is assumed that the members and librarian have the basic knowledge of internet and computers. This system ensures that the system administrator have enough knowledge of the internals of the system such as he is able to correct the small problems like disk crashes and power failure. The proper GUI, users manual, online help and the guide to install and maintain the system must be provided with the system to educate the users. System Constraints All the users information must be stored in a database that is accessible by the library system. The library system is connected to the university server and that is available 24 hours. The library system is accessible for the users who have internet connection with their computers in university. The Member Registration System, Catalog Management System, Accounting System, Email System, Fine and Reminder Bot System, Purchase Management System, and Online Client System are connected to the Library System and the database used by these systems must be compatible with the interface of the System. The users login into Library System through their username and password which they are assigned. System Assumptions and Dependencies Enough knowledge of computers should be required. To access the system online in university internet connection should be required. Library system can access the university student database. Microsoft SQL Management studio 2005 to store the database. To developed the product by using ASP.Net and C #.Net. Requirements For the Online Table Booking system following features will be provided to the customers related to table reservation. Students/Staff Requirements Search Books Search Issue Book by Student/Staff ID Search Reserve Book by Student/Staff ID Get Fine by Student/Staff Get Total Fine for Student/Staff Analysis Models Design Models The Physical design of the system is developed from logical design, which is completely based on logical design [9]. It is completely based upon the relationship among the data rather than the storage structures. The systematic organization of data which is used in automated system makes a database different form of record keeping [10]. While designing the database for the system, theses facts such as data integration, data sharing, no redundancy and data consistency have been taken care. Physical design consists of Table Design and Specifications. Database Physical Schema Tools and Technologies Tools and technologies refer to the text which describes the used and required technical specifications of the designed system. The system is a kind of information system which is targeted to be an n-tier application without losing desktop application style. The requirement to be n-tier and also to have a desktop application demands for a technology combination where following areas can be integrated to build up the system. Centralized data source Interoperability Ease of use Integrity Availability Integrating with the existing system Rapid development All these areas have their own constraints, some of which make it difficult to introduce them in a single system. While our technology study our team was working to find a solution that can help us in such a situation. In earlier stages we had an idea to provide a client server application where the data source will be centralized server and clients will call that for data services. This idea could have worked if the available time was not very short, so we left this option. Later we found a better solution to design a web application that provides the required services and we started working upon that but soon our team found a complete solution that had solved our problems. Creating a web application has some constraints which are number 2 and 3 in the above list. These constraints were removed by the new solution where we shifted to service oriented architecture and used a protocol based approach to provide data to our client application; this architecture is named as SOAP Service Oriented Architecture Protocol. Deciding finally on our system architecture we decided to use the same database management system, which is used by the university website. This decision was to support to integration of the new product with the old system and for the same reason we had used the web technology used by the website. One of the targets of the system design was to lower the cost for the deployment of the developed system, because it will only add up with the existing system and no changed will be required. On the other side no need to buy or manage or maintain any new server. It will just require simple system with required software packages installed and the system will start providing its services. Normally there will be no need to configure the client side application. The coming text will describe the software technologies which were used to design the software with their justification to use them. Server Side: Server side was build with following technologies: ASP.NET The reason to use this web technology is already described above. The website for University of Sargodha is designed using ASP.NET and is currently active and working. So to support integration with the existing web application our team decided that we must use the same technology there are using. It is very famous Microsoft technology and is used to build any kind of web solutions from simple personal websites to n-tire enterprise level web application. In comparison with other similar technologies like PHP and Java Server Pages it focuses on development of quality products rapidly. MSSQL Server 2005 MSSQL server is a database management system which is a product of Microsoft. It is very famous with medium scaled data driven business solutions. It supports client server architecture and at the same time it also provides parallel user access to the databases. Such kind of DBMS also sounds good for web technologies. In normal practice MYSQL another DBMS is used more frequent on web due to the compatibility of MYSQL with LINUX / UNIX based operating systems. MSSQL is only compatible with Windows based operating systems. Similar is the case with ASP.NET, from the introduction of MSSQL 2005 and ASP.NET both are known to be the best for each other for web technologies. The university website is also using the same combination and that is why we also are using the same technology. Web Services Web Services are a technology which is derived to provide a central source not only to provide data but also to receive data. There are many pros when we talk about this technology. Its expandability is inherited from web. Similar to a website a web service can also have unlimited number of clients, only constrained by the hosting server of the web service. This was the biggest reason to use web services in the designed solution. It does not cause change in the existing architecture of the system, but just add to the existing system. This kind of integration ability was very useful for the designed system. Web service use a protocol named SOAP which uses xml to transfer data to/from the clients of the web service. The global nature of xml enables another option in web services, that they do not restrict their clients to be the one kind of system. Any system, which can generate the kind of xml schema required for a web service and can receive and interpret the returned xml document from the web service, can call it. Another reason that made us to use the web services was the ease to call them, we called them from our desktop application where they worked just like normal routine calls, and it made it easier to proceed with the same system. Crystal Reports This technology refers to generating reports from vast data to support business decision; in our system we used crystal reports to generate several reports which are help full in providing the results regarding the library information to higher management. The reason to use this technology was to make it easier to generate reports. We concluded the ease with crystal reports from there automatic database interpretation and retrieving objects from the database schema to design reports. Reports designed in crystal reports are also not very specific to IT; their design can be modified by any designer so university is not constrained to us for required change after the deployment. Client Side: .NET The name Dot Net refers to a Microsoft technology framework which is intended to design managed and secure applications. The reason we used this framework was the ease and speed of development which is supported by .NET. The application, build on .NET assemblies needs .NET to be installed on the system where the application has to run. Our client application requires pre installation of .NET on the hosting system to run on it. The application was built using .NET 2.0 so at least .NET 2.0 or any newer version can support the application. Visual C# It is a programming language with is supported by .NET development environments. The reason to choose this language was to focus on the functionality of the system rather than bug fixing. Communication Method The server side of the system has to be deployed on a web server with the existing website. So considering this the system uses Ethernet as the communication medium to send and receive data from web services. To call/discover the web services the system uses HTTP protocol to send and receive requests to web services. Browser Technology While developing the web based interface, we have tried to make it well formed on most famous browsers which are IE6, Firefox 3.0 and Chrome 1.0. In all of these browsers it has almost similar and well formed look and feel. Another browser is targeted theoretically, which is safari. But this browser is not tested. Regarding to studied problems most of the layout is static which has a complete compatibility in all browsers. No layout uses absolute or relative positioning. System Evaluation introduction The library information management system is designed and developed using the client server architecture and is implemented

U.S. and Global Media Perspectives on Afghanistan: Evaluating the Roles of the United States and the United Nations in Preserving World Peace :: Essays Papers

U.S. and Global Media Perspectives on Afghanistan: Evaluating the Roles of the United States and the United Nations in Preserving World Peace I. Intro Afghanistan was a neutral country in the 20th century, receiving aid from the United States and Soviet Union until the 1970s. In the 1970s, Afganistan’s King Muhammad Zahir Khan was forced to deal with serious economic problems caused in large part by a severe national drought. These economic problems caused a general unrest among the people of Afghanistan, and in July of 1973 a group of young military officers took things into their own hands. King Zahir Khan was unseated, and this group proclaimed Afghanistan to be a republic with Zahir Khan’s cousin, Lt. Gen. Muhammad Daud Khan, becoming president and prime minister. Daud’s reign was short-lived; in Afghanistan’s coup d'Ã ©tat of 1978, Daud was deposed by a group led by Noor Mohammed Taraki, who instituted Marxist reforms and aligned the country more closely with the Soviet Union. These events marked the beginning of what would become known as the Afghanistan War, a devastating conflict between anti -Communist Muslim Afghan guerrillas (mujahadeen) and Soviet forces and Afghan government. Mohammed Taraki was killed in September of 1979 and Hafizullah Amin took power. With Amin taking the throne, the USSR did not hesitate to send troops into Afghanistan and had Amin executed, with the Soviet-supported Babrak Karmal becoming president. The United States, along with China and Saudi Arabia, channeled funds through Pakistan to the mujahadeen. The civil war ensued, and through the course of this war over six million people of the Afghanistan population fled the country, giving it the largest refugee population of any country in the world. By 1991-92, the US finally reached an agreement with the USSR that neither would continue to supply aid to any faction in Afghanistan. Out of these previously US funded factions rose the Taliban, an armed Aghan faction which apparently was an Islamic movement. The Taliban, funded by the CIA during this war, fought with other factions for supremacy following the departure of Soviet troops; as history would show, the Taliban became the dominant force in Afghanistan in the 1990s. The Taliban did not really exist as a coherent politico-military faction or movement before late 1994; prior to this time, they were members of other factions such as Harakat-e Islami and Mohammad Nabi Mohammadi, or operated independently without a centralized command center.

Managing project

GILL-alienation Group for Lean Construction (1993) proposed the concept of lean construction, because of the report- ‘Application of the New Production Philosophy to Construction' which was written by Laura(1992). Howell and Ballard (1997) set up LLC-The Lean Construction Institute and Introduced Lean Project Delivery System (LAPS) in order to reduce the waste at each part of project. This article will discuss on diversity contents in LAPS such as its principles, theory, ‘OFF analyses another approach, which is mentioned in the MAMBO, being used in construction as well. . Discussion . 1 the application of LAPS in construction industry LAPS consist of 4 major parts which are project definition, lean design lean supply and lean assembly. Moreover, different parts internal with each other in these 4 major parts (Ballard 2003). Project definition are required to contain all stakeholders aims and values, the concept of design as well as the criteria of design. Lean design not only needs to reflect the values, concepts 3 and criteria but also saves time to develop and explore alternatives.Lean supply is definite as an effective system which includes detailed engineering, fabrication and livery. Lean assembly consists of how to deliver the materials and how to install them. Deeply, there are 6 principles being used to guide the implementation of LAPS. These principles contain eliminating waste, build quality in, create knowledge, deliver fast, respect people and optimize the whole. They result in 5 lean approaches to management. Firstly, specify values from the perspective of the ultimate customer. Another approach is identifying the value streams meaning all steps should create value.Thirdly, creating flow is making the value-creating steps flow. Fourthly, the customer should be guided to actively pull the product from you. Finally, insistently implementation former approaches until a state of perfection is reached. According to these principles and appro aches, James (2008) analyses the whole process of construction and then make the procedure quantization in order to improve the productivity. However, the production process in construction differs from manufacturing industry in that it is more complex and unpredictable.Slake(2000) found transformation flow value generation (TFH) theory which can implement LAPS into construction industry. This theory seems construction as a special kind of manufacture. So the method we used to manage construction is called lean construction. It is a continuous process around value stream in order to satisfy all stakeholders demand and eliminate waste (Dickinson et. Al, 2004). According to the definition of lean construction 4 and TAP' theory, the application of lean construction theory can divide into maximize value, minimize waste, stream management and projects delivery.Woman et al (1996) believe that the most important thing of maximizing value is finding out what stakeholders are. During large e ngineering project construction, stakeholder is a complex and dynamic system (Bertelsmann, 2002). According to Ballard and Howell (2003), the production design and process design should be integrated in order to reduce variation in the construction process. Maximizing value means fulfilling the propose value in an acceptable cost instead of reaching the goal with the lowest price (Bertelsmann 2002).Waste can be conclude as defective product, supply more than demand, inventory, unnecessary working procedure, useless staff movement, unnecessary transportation of goods and waiting (Non, 1978). The eighth kind of waste was found that the design and service are not accord with costumer's waste. Macomb and Howell (2003) considered the information is not received which is a waste as well. Stream management has a significant influence on construction. There are 7 kinds of streams in the procedure namely, preparation work, site, staff, equipment, material, information and external conditions .In order to manage these 7 streams, people need to set up a buffer which can make the stream work effective and efficient. Project delivery is used in construction which is based on the LAPS. Ballard and Howell(1993) found the Last Planner System (PICTURE 1) which was design 5 on the rational of LAPS. In the Last Planner System, the last planner such as site administrator will be responsible for planning the resource requirement for next week. Then, manager will use Per Plan Completed (PC) to evaluate the weekly plan.Design criteria Master Schedules & Phase Schedules Work structuring Selecting, sequencing and Current situation & sizing work we think can prediction Information Preparation Order Selecting, Ranking, Workload production Weekly Schedule Resource Look-Ahead Plan be done Production Feedback Completed Work PICTURE 1 MAMBO There are several project managements are introduced in the MAMBO. Namely project integration management, project time management, project cost managemen t, project quality management, project human resource management, project communications management, project risk management, project procurement.Firstly, project integration management means the 6 method integrates consolidation, articulation, combinational characteristics as well as integrative actions which are important to complete the project, meet the customer, achieve stakeholder requirements and manage expectations. Secondly, reject time management can be defined as identifying and estimating diverse schedule activities in order to timely complete the project. Thirdly, project cost management contains planning process, estimating process, budgeting process and controlling costs which can result in an appropriate budget.Fourthly, project quality management can be divided into quality planning, perform quality assurance and perform quality control. Fifthly, project human resource management require planning the staff resource so that it can determine and improve the project te am, furthermore, using the feedback to manage the team. Sixthly, project ammunitions management is a method that sufficiently conveys the useful information to stakeholders. Seventeenth, project risk management means to predict and analysis the possible risk so that planning the response and the preventive method.Finally, project procurement management consists of planning procurement processes and communicating with sellers, buyers and administrations. 2. 3 Comparison Current management methods regard the project as a sequential, simple and predictable producing system. Furthermore, they decompose the project into activities, work package, mission and so on, every mission can be implemented independently as well. These methods all use a top-down 7 management. Planning and present under the best of circumstances. As a result, the plan does not reflect complexity, high uncertainty and dynamics of the construction.It leads to the initiative can not be well-planned and well-executed. I n contrast, LAPS seem the construction as a complex, dynamic and nonlinear producing system. The LAPS focus on the whole production system that it sets up a series of goals. LAPS underlines integrating product design and process planning, controlling them in the all product life cycle stages as well. The major preferences between LAPS and current project management focus on nine aspects. In the focus of attention aspect, LAPS more focus on the production system, but the method in MAMBO pay attention on transactions and contracts.For management object, lean project delivery looks at transformation, flow and value objects, however the current management in MAMBO focus on transformation goal. For decision making right, LAPS support to the foundation certificate in construction should take part in the decision making. In contrast, management methods in MOBS prefer to make decision follow by top-down management control system. In the design order aspect, product and process are designed together in LAPS. In MAMBO, process design will start until product design finish.For product design, designer should consider the whole product life cycle stages in LAPS. In MAMBO, designer can consider the partial product life cycle stages. For collaboration approach, all the firms in construction supply-chain should initiative cooperate with each other in LAPS. The enterprises relate with each 8 other through the market and only supply what the market demand in MAMBO. For planning, the schedule is planed from bottom to top in LAPS, but the schedule is landed from top to bottom in MAMBO. In learning aspect, learning is integrated into construction, company and supply-chain management in LAPS.

Langston Hughes vs. Claude McKay in the Harlem Renaissance

Langston Hughes vs. Claude McKay in the Harlem Renaissance Free Online Research Papers The first three decades of the 1900’s were the first time that the African American culture was taken seriously by the Caucasian community. Several factors, including the Plessy vs. Ferguson case which allowed racial segregation in 1896, led to what is known as the Great Migration. Job opportunities and far less amounts of racism were significant reasons for more than seven million African Americans moving to northern states. The concentration area of the Great Migration was Harlem in New York City. This district of New York was originally intended for white laborers who preferred to commute to the city rather than live there. The housing developers were over ambitious and had created far too much living space that white middle-class Americans were not interested in and as a result, the properties were sold to African American real estate agents who, in turn, rented the apartments out to black tenants. Between 1900 and 1920 the black population in Harlem had doubled and b ecame known as â€Å"the Black Mecca† (Biography.com). Not only did African Americans bring their labor skills to New York City, they brought their culture and their talents in art, music, and poetry. Their talents in these areas opened the eyes of their Caucasian counterparts and helped their fight for racial equality. With the excitement of these new and different ideas in the arts that finally had gotten the opportunity to emerge, the Harlem Renaissance was born. Two of the major contributors to this era were authors, (James) Langston Hughes and Claude McKay, who both, among a vast array of works, wrote poetry pertaining to the sufferings and strengths of African American culture. Although they had many of the same ideas and messages to get across in their poetry, their delivery was extremely different. Hughes’ poetry took a calm approach in which he talked about the beauty of the African American culture, while McKay was almost violent, talking about fighting for their rights rather than waiting for them to come. Hughes was born in 1902 in Joplin, Missouri and was bounced around all over the country and Mexico between his mother, father, and grandmother. He began writing at an early age and published his first book in 1926. By the time he died in 1967, Hughes had written an impressive number of books of poetry, novels, plays, musicals and operas, children’s poetry, among others, and had become one of the major contributing authors of the Harlem Renaissance (Jackson). Expressing the talents, culture, and need for African American equality was a major theme in the poetry of Langston Hughes. In his first published poem, The Negro Speaks of Rivers, Hughes metaphorically compares the soul of an African American man to a river, saying they are both deep. Rivers are often personified in poetry and used as symbols of both life and death. The rivers mentioned in this poem, the Euphrates, Congo, Nile, and Mississippi are all significant foundations for the cities that have formed near them. Using these specifically, Hughes is trying to portray the importance African Americans have had in setting the foundations in American culture. The Negro Speaks of Rivers is also greatly about African American heritage and the strength within that heritage, which the rivers also signify. The histories these rivers hold go hand in hand with the history and ancestry of African Americans. The Congo and the Mississippi Rivers both hold negative connotation with the African American slave trade but they still contribute a significant amount of depth, like the others, to the soul of the speaker, the entire African American race. The heritage of the rivers resembles the heritage of the African American people and their wisdom and strength which helped them overcome a vast array of adversity, particularly within the last couple centuries which consisted of slavery and extreme racism. The poem is also known as a tribute to the African American culture which Hughes said came from his own life. In his autobiography, The Big Sea, Hughes talks about a racist man he encountered while crossing the Mississippi River on a journey to see his father. The experience upset and frustrated him, but also got him to think about his father’s distaste for their race and Hughes’ own pride and admiration for what Hughes calls the â€Å"bravest people possible - the Negroes from the Southern ghettoes - facing tremendous odds† (Hughes). He then thought of the Mississippi as a symbol for bravery and mentioned his admiration for it in The Negro Speaks of Rivers when he talks about it turning golden as a resu lt of Abraham Lincoln’s work in the abolition of slavery. Another poem in which Hughes talks about his pride for his African American culture is I, Too. In this poem, Hughes talks about how one day the white community will be able to see the true beauty of an African American â€Å"And be ashamed† (17) of how they acted in the past. The pride he has within this poem for his culture is tied back to The Negro Speaks of Rivers. This shows that he consistently incorporates his pride in the African American community within his poetry. The main purpose of I, Too, is to express the need for equality between the separate races. He starts the poem off by declaring that ‘I’ (meaning African Americans) am an American, just the same as a white person. The second stanza talks about African Americans having to eat in the kitchen when company comes over. This stanza is talking about the segregation that is in place. When Hughes says â€Å"But I laugh, And eat well, And grow strong† (5-7), he is saying that being segregated does not bother the African American community. They are, in fact, becoming stronger people internally and in the last stanza, he makes it clear that they know that one day the segregation will be over, and they will be eating with the white people at the dining room table with the company. Hughes also says that nobody will dare tell any African Americans to eat in the kitchen, but besides, they will not want to, for they will be able to finally see and appreciate how beautiful A frican Americans are. They, too, are America. The poetry of Langston Hughes was a significant part of the Harlem Renaissance that expressed the importance of African American culture and the need for legal equality between the races. His poetry took a passive stance that looked toward the future, where he talked about the beauty African American culture holds and waiting for what is right to come to them. He did not want to violently fight for social freedom, he felt it would all come in time. The works of Claude McKay, however, took a more assertive, sometimes aggressive motion towards racial equality. He urged his readers to stand up for what should belong to them and to not let anyone get in their way. McKay was born in Jamaica in 1890 and published his first book of poetry at the age of 22. During his life, he moved to the United States, Russia, France, and finally settled in Harlem before his death in 1948. He studied Communism and wrote several poems and novels pertaining to the sufferings of African Americans (Giles). His aggressive stance that the African Americans should take on the heavy amount of racism made him an extremely important factor in the Harlem Renaissance. Growing up outside of America made the racial tension within the states more of a dramatic experience for him. After seeing the effects of the 1919 Chicago race riots that resulted in the deaths of 15 Caucasians and 23 African Americans (Essig), McKay was compelled to write a poem in response to it. The harsh language used in If We Must Die shows McKay’s sincere distaste for the way his people are being treated. The main message in this poem is that if the white America insists on persecuting African Americans, they must not surrender, but fight for their true freedom until the end. He compares the weaknesses that they have previously shown to hogs being helplessly corralled into holding areas to wait to die. In this poem, he clearly states that he is aware that the whites will probably end up murdering all of the African Americans who resist them. Even though this is true, McKay wants them to fight back, â€Å"Like men we’ll face the murderous cowardly pack, Pressed to the wall, dying, but fighting back† (13-14), he says. Unlike Hughes, he has no intention of waiting around for his lawful rights to come to him. He is best known for his poem, The White House, in which he describes the frustration he feels for being kept out of the white population and not having a voice within the country. The first line says â€Å"Your door is shut against my tightened face.† He immediately points out the purpose of the poem, to indicate his dissatisfaction with the Caucasian American population. They will not let him in to all of the rights and liberties he is owed. In the next few lines, he says that he is okay with this being shut out, because it is only making him stronger and more courageous to face these difficulties. All the sufferings that the American government has imposed on him will only make him a stronger man and make him more prepared to fight for what he feels he deserves. â€Å"Oh, I must keep my heart inviolate, Against the poison of your deadly hate† (13-14). In these last two lines, McKay is saying that even though it is going to be a long journey, in which the African American community will have fight against the extreme racism of the American government, they will keep their emotions under control and continue to pursue what it right. Occurrences like the race riots in Chicago fueled the fire for African American authors during the Harlem Renaissance era, like Langston Hughes and Claude McKay. It inspired them to write the pieces that are still read today, nearly 100 years later. The vast differences the messages their poems held are a large reason for their poetry being so dynamic and able to reach all different typed of people. Although they suffered tremendously, they were able to get their frustrations and feeling out on paper and become the iconic Harlem Renaissance writers they are known as today.
