Program „The modeling of design of multi-layer construction elements subjected by turning“ is created for students of mechanical engineering course and designers. Using this program it is possible to calculate inertia momentum of pole area, stiffness for shear, shear stresses, and maximum meanings of shear stress and twisting angle. The input parameters are shear modulus of materials, inner diameter of pivot, thickness and material of each layer, torsion moment and length of pivot. The output is initial data and results of calculation. In addition the diagram of distribution of stresses is drawn.

Aim of the work – to propose new methods and algorithms for automated deflection yoke tuning.

Using different information systems and correct communication between them are very important problem at this time. Modern companies have a large number of major applications that take care of running the business. At different times, different people used different technologies to write these applications for different purposes. Data resources can be at many different forms in organization: relational databases, object databases, XML documents and etc. Databases can operate with different systems and use distinct software. This problem must be solved by enterprise application integration (EAI) systems. The project analyzes data level EAI. This type of integration is relatively inexpensive and it doesn’t need to incur the expense of changing, testing, and deploying the application. XML can be a powerful ally for data integration. The main purpose of this project was to analyze usage of XML technologies possibilities for data integration. The problem solved is how to use the same XML flow for a several purposes: the change of another database(s), transforming to a HTML document and forming a PDF document for printing. These problems are analyzed and solved in the particular range – organization of management of public utility. Here is designed and realized an information system.

There are thousands of students being examined in universities each year. Most of those knowledge inspections are fulfilled in written form. It means that a lot of works must be checked. So many lecturers like to do examinations in a form of testing. Test - a systematic procedure that helps to measure some model of behaviour of individual for valuing that behaviour according to particular standards, norms. Tests render quantitative evaluation of skills or studies advancement and show what is being learned. Testing helps to evaluate students faster or more objective and to minimize the probability of the false evaluation. But it takes quite a lot of time to prepare tests. It’s difficult to create problematic or simulation situations in the paper test. The better way is to use computerised testing systems. Department of Practical Informatics uses small plane and 3-D geometric transformations testing system, which is pretty limited and works only in AutoCAD environment. There is no possibility of saving students’ results. This system fulfils only a part of lecturer’s requirements. The goal of the work is to create plane and 3-D geometric transformations testing (creation of tests and testing process itself) system according to definite specification. The tasks which help to reach the goal are: to review and to analyse all plane and 3-D geometric transformations; to formulate the task of the test creation and testing process support for geometric transformations; to formulate...

The main target of the information system is to provide the community of the school with the means of information that would enable its members to work more efficiently and that would give each user of the information system a tool to obtain a comprehensive and specific information. The information system of Adult Education Centre computerizes the problem of “the formation of mobile groups for the profile education”. The information system stores the information about the way of studies and the profile choice of the students, gives a wide-range information about the students’ grouping into forms and mobile groups, facilitates the processing of information, provides the statistical data. Having introduced this information system, the most part of the documents are done by means of computer and put into computer storage. The information system provides conditions for: a) the school administration to improve their work; b) the school community to obtain a wide-range and immediate information about the grouping of the students; c) obtaining information about the planning of the financial needs and the analysis of the use of the budget; d) obtaining statistical data at any time and report writing. The system is based on database. To implement the database Microsoft Access database administrative system was being used.

Mobile E-voting application system - software and hardware solution for e-voting elections. We have reviewed and analyzed present electronic voting systems, that were realized on public elections. There are many e-voting systems, but no one of them reach today’s needs, because all of them has just one, two or three voting ways, but no one has almost all and most needed of them. Another problem is security. We have created two levels security solution, to secure votes in the e-voting terminals, until they will be send to then central voting system. All mobile e-voting application system has three levels, then first is central voting station, the second is district voting station and the last is terminal. The data from the central station to the district station goes through the VPN (Virtual Private Network) and from the district station to the terminal goes through the WLAN modem. We have formed technical, information, user interface requirements and models for the mobile E-voting application system. There are described possible solutions for computer network, database and user interface. Experimental example shows a few Mobile E-voting application system functions.

It is able to summarize the OLAP definition in just five key words: Fast Analysis of Shared Multidimensional Information. The key to OLAP performance is the efficient storage of large volumes of multidimensional data. Nowadays it is released mass different commercial OLAP Web interface solutions, but it does not open source large possibility Web interface tools exist. Different analogous systems, graphics components were analyzed. Our own system and methodology were created. With this OLAP interface solution business user could review static and dynamic data reports with different type charts.

The lack of systematized information about the activity the businessmen are interested in in the region is becoming rather evident nowadays. In most cases only sites of particular organizations with incomplete and unspecified information can be found. The possibility of the creation of a united portal which would enable the businessmen to share the information and increase possibilities of business development is being discussed in this research.

The main problem in the semantic technology today is semantic metadata extraction and description. There is no general method used to extract any type of semantics. The main objective of this research is to analyze existing methods that are used for describing and extracting semantic metadata and to design a metadata extraction system for Lithuanian. The quality analysis of designed system is carried out according to ISO/IEC 9126 standard. The objective of this standard is to provide a framework for the evaluation of software quality. ISO/IEC 9126 does not provide requirements for software, but it defines a quality model, which is applicable to every kind of software.

The main purpose of this work is to develop an information system „Managers Window“ for managers of Lithuanian Labour Exchange. The objectives of this system are:  To provide actual information about management indicators and their analysis  To control the level of achievement of labour market indicators (2 level system)  To evaluate quick the situation and review of trends in labour market  To give possibility to compare activities of several labour exchanges at once System functions:  To reload data from jobseekers and vacancies database (IS DBIRŽA-I)  To parametrize indicators (indicators are divided by specialists, responsible for task implementation)  To review general results of indicators and analyse their details  To draw diagrams to show current situation in management indicators Other features of the system:  Ability to complement system with additional data from other databases, internet or intranet sites;  Ability to exchange data charts and tables with other Office software The IS is implemented using software package QlikView.
