Aprašėme analizei naudojamus įrankius, jų veikimo principus ir pateikiamus rezultatus. Paskutinėje darbo dalyje ištyrėme ir eksperimentiškai išbandėme naujai realizuotas mūsų pasiūlytas taisykles. Palyginome testų rezultatus programų veikimo našumo charakteristikos aspektais. Įrodėme mūsų programinio kodo statinės analizės taisyklės privalumus. / This final master’s thesis consists of three major parts. The first section covers engineering aspects of source code management system called “SourceHQ” that we developed, including its analysis and design details. We will provide key details and basis of chosen technologies, business analysis, and design decisions as well as discuss system functionality and its future prospects. The second part is dedicated to testing and ensuring system quality, which led us to design and develop custom static source code analysis rules. We will formulate and explain their potential use and benefits. We will describe additional tools and methods being used and provide main results of static source code analysis. In the final part of our work we go deeper into static source code analysis. We perform experiments based on our designed and developed custom rules on various .NET Framework applications and systems. We cover major performance benefits and drawbacks of every rule separately and display how this approach lets developers optimize their source code in an early development stage. We provide research data based on extensive experiments and conclude how using FxCop tool provided with our improved custom code analysis rules can automatically discover and suggest improvements in CIL code.

To increase the productivity of electronic systems design we offer to use UML – the standard specification language of high level systems. The higher level of abstraction and automatic design methods could decrease a gap of hardware design. We offer to use UML class diagrams for the specification of electronic systems structure and UML state diagrams to specify the behavior of electronic systems. We introduce metamodels which describe mapping between UML class and state diagrams and hardware description languages (VHDL, SystemC), as the possible realization of ideas we introduced earlier. Also we provide code generator which translates notations of UML class and state diagrams to VHDL and SystemC languages.

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.

Per pastaruosius metus, lankstaus programavimo metodikos sulaukė daug dėmesio. Programų kodo pertvarkymas tapo viena iš labiausiai naudojamų praktikų, ypač ekstremaliame programavime. Todėl poreikis turėti programos kodo pertvarkymų įrankį išaugo iki tokio lygio, kad pertvarkymo įrankiai tapo reikalaujama priemone šiuolaikinėse programų kūrimo aplinkose. Tyrimo sritis – abstrakčios sintaksės medžių pertvarkymo algoritmai. Tyrimo objektas – abstrakčios sintaksės medžių pertvarkymo procesai skirtingose programavimo kalbose (C++ ir Java). Šio darbo tikslas – ištirti, kaip efektyviai būtų galima vykdyti pertvarkymus bendriniam AST, tam sukuriant pertvarkymų biblioteką ir atliekant eksperimentus įvairių kalbų atvejais. / Over the past years, agile development methodologies have attracted a lot of attention. Refactoring has become one of the most heavily used practices, especially in Extreme Programming. Therefore the need to have powerful refactoring tools has grown to such an extent, that there is a required feature for modern-day IDEs to have implemented refactoring tools. The aim of this work is to build a refactoring library for the generic abstract syntax tree and test the algorithms for speed. Generic abstract syntax tree (GAST) is a tree structure that can store elements of several programming language. Achieving this goal required doing certain tasks that you find in this document: analysis of technologies and existing software; several algorithms for refactoring; user need and specification of requirements; library model, expressed in UML diagrams; test plan and test procedure. Experiments have shown that it is necessary to improve the refactoring algorithms. But the library and the AST structure is worth further development.

For effective remote learning realization we need the complex intelligent remote system, which would keep special and structured material for learning and tests of knowledge. Feedback is the most important thing for learning. In the usual way feedback takes a lot of teacher time, therefore it is very useful to practice electronic system functions for control of feedback and reduction of teachers work time. Creation of complex intelligent eLearning system needs profound knowledge of programming, pedagogical and strategic knowledge, therefore this work would be impossible for one person. The knowledge of study is very important too. Therefore we could use made-up open source remote learning system and readjust for our interests. We use remote learning open source system Moodle and use this system in practice. From practice in lessons of informatics and ECDL learning planning we could propose that this system is really very flexible and useful in learning processes. The suggestion of new well-tried remote learning method – learning with tests show that it is very effective method in learning processes.

The majority of households in the hill regions of Nepal are net consumers of their agricultural produce. The harsh geographical topography, low landholdings and uncertain weather make households in the hills more susceptible to food insecurity. This research examines the role of small millets in achieving food and livelihood security for the people of Dhikur Pokhari VDC in Nepal. As a project based on qualitative research, data was collected through semi-structured interviews, observations and focus group discussions. In addition, market and value chain analysis for small millets was conducted. The findings show that small millets have a significant role in ensuring food security, particularly for the marginalized households. The findings also show that, through their exchange properties, small millets contributed towards generating household livelihoods. Further, findings revealed the existing formal and informal markets for small millets and showed a direct correlation between small millets-based market, and food and livelihood security for the people of Dhikur Pokhari VDC.

This master thesis covers re-engineering methods of legacy systems. Legacy system is an old system, which is hardly compliant with modern technologies and used only because it has become an integral part of organization business process support during the long period of its maintenance. These systems are large, monolithic and difficult to modify, and cost and risk of their replacement are difficult to predict. The science of software engineering offers an incremental modernization of information systems applying the re-engineering of legacy software. The main goal of software re-engineering is to transform the software in the way, it would become easier to understand, maintain and re-use, at the same time preserving its useful, time trusted functions. The main re-engineering methods are source code translation, reverse engineering and data re-engineering. This thesis covers the analysis of these methods, which was made during the re-engineering of wood production and sales accounting system. The adoption and realization time rate of every method was examined. The influence of the applied re-engineering methods to the system reliability, efficiency, usability and other quality metrics is given.
