With the Internet being widely spread, databases are becoming more and more accessible. Unfortunately, this process brings some problems alongside obvious advantages. Easily accessible information causes raise of plagiarism, a phenomena of people finding some creative works, slightly (if at all) changing them and presenting as their own pieces. This work presents an overview of various methods that can be used in computer software in order to automatically perform document analysis and comparison for detecting similarity instances. In the work, such software development stages are given as well as software testing and considerations on semantic message analysis method integration in the system.

In this work, the Internet Information System is created for the Artists‘ Association. It was planned to meet the specific needs of the Artists who wanted to let the people know about themselves and their works, and finally sell them. It also meets the needs of every Internet user who might be interested in information about the popular or perspective artists and who might purchase their works. The system was developed on the basis of .NET technologies: ADO.NET, ASP.NET and programmed with Visual C#. The data of the information system are stored in MS SQL Server 2000. Finally the information system was implemented and thoroughly tested. It meets all the functional and non-functional requirements of end users: the Administrator, the Artist, the Registered User and Internet User. The system is safe, fast, and comfortable to use, has good look, and may be extended in future when the needs of its users would grow.

Data flow and computing resourses in large scale LED screens calculation and analysis is presented. It has been proved that due to specifics of LED screen control large data flows are born which for a reduction. Also, there is a demand for LED screen control hardware price reduction. By application of distributed computing by means of screen processors implementation in comes possible to reduce the data flow load on main processing unit. Thanks to this personal computer can be implemented for screen control as main processing unit. Due to above mentioned modifications PC becomes responsible only for data format unification. Main data processing is implemented in distributed network of screen processors. This further allows to use standard ethernet transmission and distribution equipment, leaving space for system future development.

Pagrindinis darbo tikslas - realizuoti programinę įrangą, gebančią automatiškai testuoti vartotojo sąsają ir testinius atvejus generuojančią iš duotų UML modelių. Kuriama programinė įranga turėtų būti realizuota naudojant Java technologiją. Taigi šio darbo tyrimo sritis apims vartotojo sąsajos testavimo automatizavimo būdų analizę. UML modeliai tapo ypač populiaria priemone modeliuojant programinės įrangos architektūrą. UML modeliai šiais laikais naudojami ne tik įprastoms klasių diagramoms, veiklos diagramoms, sekų diagramoms modeliuoti ir pan., bet tampa vis populiaresnia priemone ir yra taikomi daugelio kitų projektavimo uždavinių sprendimui. Vartotojo sąsajos atvaizdavimas UML diagramomis vis dar nėra populiarus būdas, nors literatūroje vis dažniau sutinkame siūlymų naudoti šias technologijas. Taigi literatūroje atsirandantys straipsniai, vykdomos konferencijos ir panašaus pobūdžio įvykiai byloja, kad ateityje ši technologija neaplenks ir vartojo sąsajos modeliavimo proceso. Rinkoje jaučiamas vartotojo sąsajos automatinio testavimo sistemos, kuri gebėtų testinius atvejus generuoti iš UML modelių ir automatiškai vykdyti testavimą, trūkumas. Tokia sistema galėtų būti naudojama efektyvesniam testavimui atlikti. Tokia sistema gebėtų testuoti vartotojo sąsają greičiau ir tiksliau. Greitis pasiekiamas tuo, kad automatinio testavimo procese nedalyvauja žmogus, o visą testavimą atlieka įrenginio procesorius. Testuojant sistemą skirtingose platformose testavimą galima atlikti... [toliau žr. visą tekstą] / In many cases, testing is an essential, but time and resource consuming activity in the software development process. In the case of model-based development, test construction and test execution can be partially automated. As the application size is constantly growing, the need for automated testing frameworks comes into place, particularly frameworks for automated testing of user interaction and graphical user interface. This document describes an implementation of the GUI test generator framework based on UML models where specific UML activity diagrams are used for test case generation. It is not a usual case to use UML activity diagrams for UI modeling. However the existing stereotypes of activity diagram elements are not suitable for UI modeling. With usual activity diagram it is complicated to define buttons, containers, pages and other UI elements in the diagram and find differences between them. Even more complicated is to model the navigation of the testing application. Using this approach the UI can be defined in a set of UI elements along with a set of UI navigation elements. This is an optimal and suitable approach in most cases. This document describes an implementation of the automated GUI tests runner framework as well. This framework is able to run the given application in test mode using the previously generated test cases. The framework collects all the information about each test case results and provides it to the tester. Future improvements: Find the... [to full text]
