Šio darbo tikslas yra išnagrinėti neuroniniu tinklu paremtą prakybos strategiją, Markovo strategiją ir branduolių metodą, taip pat sukurti sudėtingesnį neuroninį tinklą ir visa tai pritaikyti valiutų rinkos duomenims. Analizei naudoti euro ir JAV dolerio valiutų poros kaina, kuri apima 2011 lapkričio 1 d. – 2012 gegužės 15 d. periodą. Nagrinėjama šios valiutų poros uždarymo kaina valandiniu periodu. Atlikus minėtą analizę, gauta, kad geriausius prognozių tikslumo rezultatus rodo neuroninio tinklo strategija, po to seka branduolio metodas ir galiausiai lieka Markovo strategija. O sukurto sudėtingesnio neuroninio tinklo rezultatai nėra labai geri. Analizuojant jungtinius metodus, gauta, kad tikslumas daugiausiai išauga jungiant visus tris metodus. Bet toks junginys generuoja mažiausią kapitalą. Šitai sąlygoja, kad lošiama tik kas trečiame raunde, o visais kitais atvejais yra atsisakoma nuo sprendimo priėmimo. Išnagrinėti metodai yra verti dėmesio, o kurį rinktis, priklauso nuo paties žmogaus, nes kur didesnis kapitalas, ten didesnė ir rizika. / The main aim of this work is to analyze a strategy based on the neural networks, Markovian strategies and kernel method, also to create more complex neural network and apply it all for the data of foreign exchange market. Euro and U.S dollar currency pair price was analyzed during the 1 November 2011 - 15 May 2012 period. The closing price of the hourly period was analyzed. The analysis revealed that the best forecasting accuracy shows neural network strategy, followed by the kernel method and end up with Markovian strategy. The results of created more complex neural network are not very good. The analysis of the joint methods revealed that the best accuracy obtained by combining all three methods. But it generates smaller capital than others. It happens, because bets are made only in the third of rounds, and in all other cases there is refusal to make decision. The methods are worth of attention, and which one to choice depends on the person, because bigger capital leads to higher risk.

Graphs are a pervasive data structure in computer science, and algorithms for working with them are fundamental to the field. There are hundreds of interesting computational problems defined in terms of graphs. This time we’ll touch one of them – the problem of maximum net flow. One of the main problems in the theory of graphs is the problem of maximum flow. The purpose is to calculate the biggest amount of matter, which can be relayed from the source to the flow. This is one of the easier tasks, which can be solved with the help of algorithms. Beside that the basic algorithms of maximum flow can be used for solving other problems about net flows. The results of this work are: - created the program equipment, realizing four classic methods of calculating maximum flow – Ford-Falkerson, Edmonds-Karp, Dinic and Goldberg; - with the help of this program equipment is collected the statistic of these methods efficiency. Results showed, that every method can be realized within shorter time as was proved earlier.

The idea of this work is to propose a method of Web data aggregation employing ontology. This method is required as a part of major method proposed by Vytautas Taujanskas and Rimantas Butleris in paper “Categories extraction for reuse in semantic applications and profile based recommendation service” [1]. The main task of the method aims to semantic portal users who request to get information according their profile settings based and described with meaningful semantics. The requirements of method are created based on requirements of Semantic Web implementation and Semantic Web Services concepts. The vision of Semantic Web, Web Ontology Language, Resource Description Framework, Semantic Query Language for RDF, Ontology tools and frameworks issues are discussed. Also the main techniques of current Web for data syndication, aggregation and publishing in various feeds formats (Atom, RSS) among users are introduced. The proposed method integrates available techniques and creates possibility of aggregated data storing in ontology based databases. The data represented by ontology can be re-used by another system without loosing semantics and more flexible. The project model of method implementation was created and implemented by using JAVA programming language combining available techniques described in analysis phase. The experiment with test data and use case tests shows that method can be implemented successfully with available tools as a part of Semantic Web application.

Algorithm computes optimal shortest path and works on any wireless sensor networks topology. One of the limitations of wireless sensor nodes is their inherent limited energy resource. The limited available energy of sensor nodes is mainly problem making communication and computational processing. An energy efficient routing protocol can limit the number of nodes transmissions and the computational complexity of finding the shortest routing path. In the experimental part, the correct functionality of the algorithm is evaluated and the results are analized.

The main goal of this project is to analyze structure, possibilities, principles of creation, users requirements and extend functionality of the present system (ViPS), which is designed for distance education. This system gives possibilities to Lithuanian institutions of science and education to supply distance studies in all over the country. Besides that, it gives possibility of life-long learning to all people. System is oriented to synchronous education, but it also supports asynchronous. Material of lectures contains of video records and lecture material (usually slides) made by professor. ViPS can be used by four types of users: lecture listeners (outside users), professors, institution and system administrators. Users activities are: • Outside user – has an opportunity to look through the list of courses, participate in lectures, get news by email, execute search, change data of profile and accession. • Professor – despite outside user’s functions, can also give lectures, describe courses and lecture material (metadata). • Administrator of institution – despite professor’s functions, has a possibility to attach non-grouped users to institution, give special access rights (can change user status to professor) to users, register institution resources. • System administrator – despite institution administrator’s functions, can create groups, send system news to users, create licenses, register institutions, control user groups.
