Viena iš technologinių sričių, kur galima pritaikyti modeliavimu grindžiamą architektūrą (MGA) yra Java Enterprise Edition (J2EE) informacinių sistemų kūrimas. Nors generuoti pilną programinį kodą taikant MGA metodus nėra įprasta, tačiau egzistuoja abstraktūs metodai, bei daliniai sprendimai leidžiantys daryti prielaidą, kad tai yra įmanoma. Remiantis egzistuojančiais abstrakčiais metodais ir daliniais sprendimais buvo sukurtas MGA metodas ir kodo generatorius, leidžiantis sugeneruoti visą programinį kodą pagal modelio duomenis. Sukurtas metodas buvo išbandytas su realia informacine MagicTest žinių testavimo sistema. Bandymas su realia sistema parodė, kad pasiūlytas MGA metodas gali būti sėkmingai taikomas JEE platformos informacinių sistemų kūrimui. / One of the technological areas where can be used model driven architecture (MDA) is Java Enterprise Edition (J2EE) development of information systems. Although to generate a complete program using MDA is not common, but there are some abstract methods, and partial solutions suggesting that this is possible. Based on existing methods of abstract and partial solutions new MDA method and code generator was created. Generator allows to generate software code based on the model data. The method and generator was tested with the real information MagicTest knowledge testing system. The test of the real system showed that the proposed MDA method can be successfully applied to J2EE platform for developing information systems.

Learning complex systems is a challenging task. The learning curve often depends on what experience the learner has and how familiar he is with the system domain. Particularly beginner may face serious problems in understanding the details of complex systems like various software platforms, standard API’s or formats. The understandability of a complex system can be improved by graphical representations. A good candidate for the graphical description of software-related systems is the Unified Modeling Language (UML), which is a widely used standard design notation and thus assumingly familiar for most software engineers. Such a graphical description effaces unessential technical details like the intricacies of a particular textual syntax or implementations of methods, and shows the abstract relationships between the different parts of the system. The class models generation features of Case systems are described in this work. Reviews of object orientated software design tools are given. Reviewed tools hold UML notation and abilities to fully or partly generate programmer code. Tools comparison tables are presented. After evaluation of Enterprise meta model, Class meta model was improved. There is enough information in Knowledge basis to generate Class meta model. This work presents the algorithm of generation of activity of class model on the basis of enterprise model and its specification. Results of the step of the algorithm are illustrated graphically by UML notation... [to full text]

Nuotolinės video-okulografinės akių judesių matavimo sistemos turi mažiausią invazijos lygį, todėl yra labai paplitusios ir sparčiai vystomos. Tokios sistemos pagalba Šiaulių universitete, Technologijos fakultete įsikūręs Biomedicininės inžinerijos mokslinis centras atlieka tyrimus, susijusius su akių judesiais. Akių judesių tyrimui mokslinio centro darbuotojai dažnai naudoja tolygia trajektorija judantį taikinį. Taikinio vaizdavimui naudojamas OpenGL metodas. Šiame darbe tiriamos OpenGL metodo taikinio judėjimo trajektorijos koordinačių generavimo galimybių ribos, metodo tikslumas, spartinimo galimybės ir atliekamas lyginimas su kitu galimu taikinio judėjimo trajektorijos koordinačių generavimo metodu. / The permanent systems of video-oculographic movement measuring have the lowest level of invasion, therefore are very common and expeditiously developed. The Scientific Centre of Biomedical Engineering situated with the help of such system in Šiauliai University, Technology Faculty performs researches in relation with the movements of eyes. The workers of the scientific centre usually use a target moving along an even trajectory for the research eye movements. The method OpenGL is used to depict the target. In the present thesis, there are researched the limits of the possibilities of generating of the coordinates of the OpenGL target movement, the accuracy of the method, the possibilities of accelerating and there is performed the comparison with another possible method of generating of the coordinates of a target movement trajectory is performed.

Kaunas: Vilnius University, Kaunas Faculty of Humanities, Departament of informatics 75p. Summary Main objective: Create a method and realization algorithms for UML sequence model based on enterprise model generation. Main tasks: • To analyze the work domain: knowledge based IS engineering • To implement enterprise metamodel’s content analysis through the prism of UML sequence metamodel • To create the way (algorithms) to generate UML sequence diagram. • Suggest a software prototype for created method. • To test the software prototype using real world data. Research domain: design stage of knowledge based IS engineering. Research methodology During the research main methods used were analysis and synthesis comparing, analysis of science literature and Internet sources, model creation, analysis and decomposition. Results: The analysis of work domain was implemented. Enterprise model structure was analyzed through its metamodel. Enterprise metamodels structure was compared to the sequence metamodel and it was found that the enterprise metamodel in not sufficient to create a sequence diagram. Therefore the enterprise metamodel was complemented with additional concepts. The sequence diagram generation algorithm was created and tested with a software prototype. Consequences: After enterprise metamodel and sequence metamodel decomposition and analysis there was designated that... [to full text]

The tasks generating and their answers automatic checking problems of web-based assessment and testing systems was formulated in this document. The main tasks for thesis were set. The similar systems were analyzed and possible solutions reviewed. In this case, was decided to design the tasks generating and automatic checking software, which will resolve the tasks, brought to user’s recurrence, improve the skills checking. The technologies for this project realization were choused. The created software system was tested and the quality analysis was made. Finally, the experimental research was accomplished. All the research results showed that the raised problems were resolved.

In this work the main aspects were discussed that need to be evaluated by establishing graphical user interface. There were discussed some user interface languages and technologies such as XML, XUL, XIML, XSLT, CSS, XHTML, analyzed some used methods for automated user interface generation. On a basis of this analysis, the proper method was chosen to apply for generating of user interface using ODRES method results. On the next stadeges of the work it was designed and developed prototype of the GUI generation system. The main goals were to develop cross-platform user interface, using as mutch as possible simplyer technologies along with that securing constant design on different web browsers. Generation process operates using the GUI specification stored in the MS SQL database and converting it to XML and along with the XSLT files used as parser. After these files are opened using web browser, XML and XSLT code is processed to an XHTML code. The process of the user interface generation is flexible and alows user change GUI’s appearance on the fly adjusting it’s specification stored on the database or XSLT rooles as well. During this work were made some ot the modifications to the ODRES database: appended few more attributes, describing graphical elements characteristics and web form relations; added extra tables.

Programinio kodo generavimo iš veiklos taisyklių modelių sritis iki šiol yra menkai ištirta ir tai neigiamai veikia veiklos taisyklių koncepcijos plėtrą. Nagrinėjama kodo generavimo iš grafinių IS (informacinių sistemų) reikalavimus atspindinčių modelių problema. Pristatomas modifikuotu Roso metodu grindžiamo veiklos taisyklių modeliavimo IS projektavimo stadijoje metodo tyrimas, siekiant sukurti adekvačią programinio kodo generavimo iš taisyklių diagramų metodiką. / One of the reasons for a relatively slow growth of the business rules approach could be the lack of developments in the field of program code generation from the business rules models. During this work methods for code generation from IS requirements models are analysed. The focus is placed on a modified Ross method based rules modelling method aiming to create an adequate code generation methodology.
