Baigiamajame magistro darbe pateikti praktiniai sprendimai, leidžiantys efektyviai rasti, išgauti ir vizualizuoti tinklapių medinę struktūrą. Tam yra sukurtas vizualiai tinklapių struktūros analizei atlikti skirtas instrumentas. Darbo tikslui pasiekti atlikta mokslinio potencialo analizė, parinkti efektyvūs metodai ir papildyti, atsižvelgiant į sprendžiamą darbo mokslinę ir praktinę problemą. Praktiniame darbe panaudojant class menu artumo bei urlmetodus ir taikant Prefuse vizualizaciją sukurtas instrumentas, leidžiantis ženkliai pagerinti svetainės navigaciją, struktūrą bei patobulinti svarbiausios informacijos pateikimą lankytojui. Gauti rezultatai leidžia efektyviai analizuoti, kurti, plėtoti ir vertinti tinklapių medinės struktūros navigaciją, tinklapio elementų ryšius ir vizualizacijos procesą. / This Master‘s thesis is contemporary and relevant as more efficient and convenient control of sitemap navigation and visualization is beneficial both to the user and creator of such systems. A simpler, faster sitemap, more effective visualization and more convenient structural menu are comprehensively valuable for website users. Therefore the object of this thesis is the creation of the tool which would ensure the visual analysis of site map. This Master‘s thesis contains practical solutions how to make sitemap data extracting, filtering and rendering more effective. The goal of this thesis is to create a tool, ensuring a more efficient sitemap data extracting, filtering and visualization. Therefore to achieve such goal, author forms the following tasks: to research and detect most efficient methods of work; to create an individual method for website sitemap extracting and filtering after applying class menu and url methods and also modifying them with classification and consolidation methods at first; successfully visualize data with the use of created tool. The tool, which improves website map filtering, extracting and rendering is created in the practical part of thesis by applying methods and Prefuse instrument. Obtained results allow us to upgrade and develop website navigation process, through association and visualization information even more efficiently. This project is implemented with JAVA, Python languages. „Microsoft Office Visio 2003“ is used for representation... [to full text]

Nowadays the majority of the companies stocking services of central heats face to the necessity to modernize the sources of the heat generation. In this Master’s Work there are analysing “Radviliškio šiluma” companies feeding the heat, boiler – houses in Radviliškis, the opportunities of the investments in order to reduce the prime cost of feeding the heat in their heat system. There are analyzing these alternatives: the basic variant, the peat burning, the cogeneration installing, and the optimization of the individual parts of the pipeline in the heat system. All alternatives are compared using the method of the proximity to the ideal point. In order to appraise the results there was used the computer tool energyPRO. This computer tool summed up the constant and permanent inputs, the inputs of the system’s service, the inputs of the waste, and the costs of the environmental pollution and the prime cost of the heat energy. There was estimated the way of the optimal heat feeding – the cogeneration installing - comparing the significance of the criteria of the evaluation. The method of the proximity to the ideal point could be used in comparison of other alternatives and criteria of the evaluation.
