The short analysis of vibromotors and rolamite ty¬pe mechanisms is submitted, their advantages are revealed.Dynamic processes, occurring in vibromotor, are investiga¬ted experimentally in which the slanting impact of the converter of longitudinal fluctuations to a rotor is used, and rotates it.It is established that optimum corner of elastic pressing of the converter of longitudinal fluctuations to a rotor makes 125° and the greatest revolutions of a rotor is got. The size of elastic pressing of the converter of longitudinal fluctuations to a rotor unsignificantly influences the form of the mechanical characteristics. It is recommending for precision systems working in a wide temperature range and at linear and vibrating overloads to use the circuits with included in a contour of the generator by converters or to construct auto oscillatory generators working on resonant frequency of the converter. The value ofnon-synchronicity of rotation of rotors mostly grows in elementary vibromotor with two rotors, least – in rolamite vibromotor, in which the converter of longitudinal fluctuations rotates both rotors. The variant of rolamite vibromotor, in which the converter of longitudinal fluctuations rotates both rotors, is optimum. The synthesis of the rolamite type mechanism and vibromotor allows to design qualitatively new original mechanisms.

Software development process encounter productivity obstacles, which are affected by an arise of new technologies. Object Management Group (OMG) proposed model driven architecture (MDA) supposed to minimize effect of new technologies arrival into a process of software development. One of the most important aspects in MDA is meta-model, which is used to specify MDA style transformations. Theses present meta-model of PLA model and XSL transformations, used to retrieve PLA simulation model. Example of creating oil terminal simulation model is presented as well.

Darbe tyrinėjama veiklos taisyklių koncepcija ir jos taikymas projektuojant informacijos sistemas. Pagrindinis tyrimo objektas yra kompiuterizuotas grafinis veiklos taisyklių modeliavimas informacijos sistemų projektavimo stadijoje. Tyrimo tikslas: atskleisti grafinio VT modeliavimo greta UML galimybes, sukuriant ir išbandant modifikuotu Roso metodu grindžiamą MagicDraw UML įrankio įskiepį, kuris leistų modeliuoti veiklos taisykles, užmezgant ryšius tarp taisyklių ir esamomis MagicDraw UML priemonėmis sukurtojo duomenų modelio (klasių diagramos) elementų. / Information system (IS) modeling is popular and constantly developing. However there is a wantage for solutions of realization of computer engineering activities in the business rules based methods. One of the most prominent of this kind of methods is the Ross method, allowing the creation of formal business rules graphic models. This work specifies and implements business rules modeling tool, which use Ross method, into computer engineering tool MagicDraw UML as plugin.

Online commerce and service obtain much private data from users. Collection, storage, management, and use of private data are subject to various privacy laws, regulations, and standards. To adhere to legal requirements, many privacy services, such as security, notice, and consent, are required. Inclusion of the required privacy services early in the life cycle of the software development is preferred and advocated. We extend UML use case diagrams with privacy components to represent example privacy services. These components are used to visually model privacy requirements in the analysis phase of the SDLC. We create a prototype by extending Microsoft Visio, a popular UML modeling tool, with our proposed privacy components. In summary, we show how privacy services may be specified in UML use case diagrams rather than adding privacy as an afterthought to software systems and services. The tool is demonstrated with real-world scenarios from the health sector.

Nowadays possibilities of creation of web applications dedicated for information presentation a rapidly increasing, and more universities and other education organizations prefer to publish the information they gathered in specialized information portals. This solution allows effective use of all methodical and practical material, collected in organization. More universities in all over the world made their decision on specialized portals of knowledge, internet thesaurus. These web applications allows present information in different views and connect related data. Using this solution gives possibility to search for useful information from all over the world, 24 hours a day, so this gives chance to improve possibilities of distant learning. In this work web thesaurus is presented as an example, how specialized web application can help tu publish methodical and practical information and gathering terms of theory and their descriptions. Also presented analysis of existing methods for creating specialized web applications and description of method, created for modeling web applications analogical to web thesaurus. There are special solutions described for creating of multilingual web applications, effective system resource using, creating useful search system and context menu or content management mechanism.
