This Master‘s thesis is dealing with the usage possibility of education application for internet environment in learning process. Nowadays, this kind of applications is called the E-learning system. Theoretical part is focused on basic principles, describes the reasons why are these systems so popular and used world wide. Negatives and positives of both, the e-learning system as well as the classic form of studying are described. Content of this part also shows the usual usage cases. Practical part deals with construction of the particular system, based on requested features. The main system was divided into the two main logical parts. Their functionality is well described. In this part also all used programming languages as well as tools and server operation systems are mentioned. Practical part is also used to show information about database system and description of the particular database which was created. In the conclusion can reader find the summary of all practical and theoretical results achieved during the work on the project.

This diploma thesis deals with description of methods and original on-line application for solving multicriteria evaluation of alternatives problems. Methods based on maximisation of utility value (WSA), minimisation of distance from ideal alternative (TOPSIS), evaluation of preference relations (ELECTRE) and evaluation along preference flows (PROMETHEE) are described and implemented in the application. The thesis introduces an original web application written in PHP language which is developed for solving multicriteria evaluation of alternatives problems in internet environment. The application running on web-server allows solving multicriteria evaluation of alternatives problems by four above mentioned methods. The application is controlled by any web browser. A run-time complexity of used algorithms is measured and discussed.

Internet in recent years has changed quite a lot, usual static user interfaces poorly satisfy user's requirements or do not at all. That is why there is a need to analyze a new breed of internet presentation-level technique – rich internet applications (RIA). Main RIA technologies and several internet projects were analyzed in this thesis. Macromedia Flash technology was chosen because of its flexibility, multiplatform implementation, rich user experience, good integration among various server technologies. An experimental system named Ferry transport booking system was built using Macromedia Flash technology and implemented with Microsoft server technologies. Experimental research of this project is described; a comparative analysis of rich internet application and simple static interface advantages is provided.

Title: Interactive crawling and data extraction Author: Bc. Petr Fejfar Author's e-mail address: pfejfar@gmail.com Department: Department of Distributed and Dependable Systems Supervisor: Mgr. Pavel Je ek, Ph.D., Department of Distributed and De- pendable Systems Abstract: The subject of this thesis is Web crawling and data extraction from Rich Internet Applications (RIA). The thesis starts with analysis of modern Web pages along with techniques used for crawling and data extraction. Based on this analysis, we designed a tool which crawls RIAs according to the instructions defined by the user via graphic interface. In contrast with other currently popular tools for RIAs, our solution is targeted at users with no programming experience, including business and analyst users. The designed solution itself is implemented in form of RIA, using the Web- Driver protocol to automate multiple browsers according to user-defined instructions. Our tool allows the user to inspect browser sessions by dis- playing pages that are being crawled simultaneously. This feature enables the user to troubleshoot the crawlers. The outcome of this thesis is a fully design and implemented tool enabling business user to extract data from the RIAs. This opens new opportunities for this type of user to collect data from Web pages for use...

Vi lever idag i en värld där sprickan mellan vad som går att skapa med en desktopapplikation och vad som är möjligt att implementera på en webbsida har blivit mindre än någonsin. För tio år sedan var det inte möjligt att skapa avancerade affärssystem på en webbklient, men i och med att tekniker har utvecklats och nya språk har skapats har även nya möjligheter öppnats framför våra ögon. Frågan är var gränsen går? Vad kan vi egentligen skapa med de webbramverk som finns tillgängliga idag. Det är en av frågorna denna rapport ska svara på. Idag finns det en stor mängd ramverk för att utveckla så kallade Rich Internet Applications, komplexa och dynamiska program som körs direkt från webbläsaren. Dessa har alla olika styrkor och svagheter som är mycket svåra att känna till om man inte studerar ramverken noggrant. I denna rapport beskrivs ramverken Adobe Flex, JavaFX och HTML5. Läsaren kommer få en tydlig bild av hur ramverken kom till, vad de bygger på för tekniker, hur koden ser ut för dem olika samt vad de använder för tekniker för att kommunicera med applikationer skrivna i andra språk. Rapporten kommer även klargöra vilka tekniker de stödjer för att skapa ett snyggt och anpassningsbart grafiskt gränssnitt, hur komponentstödet är utformat och huruvida man kan skapa modulära program med ramverken. Detta kommer utmynna i en analys där ramverkens för- och nackdelar sammanställs vilket slutligen ligger till grund för att jämföra dem med varandra och avgöra vilket ramverk som är bäst anpassat för att skapa omfattande desktopliknande applikationer på webben.

This diploma thesis deals with development of web applications using Google web Toolkit. GWT is modern set of open source tools that allows developers to create Rich Internet Applications completely in Java without any deep knowledge of JavaScript. The theoretical part of this thesis is focused on architecture of Google Web Toolkit, basic approaches and some advanced topics as MVP architecture, client-server communication or persistence layer. The practical part consists of set of examples which demonstrates approaches described in theoretical part.

De nos jours, les projets d’architecture font participer de nombreux acteurs différents de plus en plus éloignées géographiquement et cependant regroupées dans le cadre de l’élaboration d’un seul et même projet. Intégrer les points de vue de tous ces acteurs de la conception en prenant en compte le cycle de vie du bâtiment suggère une certaine « transversalité » de la conception et est rendu possible par une prise en compte très tôt dans les processus, de contraintes ou de paramètres gérés beaucoup plus tard dans les organisations traditionnelles. Cette étude souligne l’exigence forte d’une conduite de la conception pour améliorer la qualité de cette dernière et réduire ainsi l’apparition des dysfonctionnements. En ce sens, nous mettons en exergue les caractéristiques multidisciplinaires et les aspects prédictifs et réactifs de la conduite de la conception en architecture. Ensuite sur la base des modèles cognitifs existants, nous proposons un modèle combinant de façon simple trois activités primitives (analyse, proposition, évaluation). Ensuite nous enrichissons ce modèle pour couvrir les aspects prédictifs et réactifs de la conduite de la conception. Cela se fait sur la base de notre analyse de la conduite de la conception qui a permis de révéler deux entités, généralement implicites mais omniprésentes dans les projets de conception : la situation problématique et la situation visée. Enfin, nous spécifions et présentons une maquette d’un outil d’un niveau supérieur par rapport aux outils existants et qui peut être qualifié d’outil réactif. Cela signifie qu’il ne permet pas de définir une solution, mais de déterminer quand l’intervention de l’acteur pilote est souhaitable / Nowadays, numerous architecture projects require different actors who are more and more remotely located to work together on the elaboration of a common project. The inputs of these actors of design need to be integrated by taking into account the life cycle of the buildings, which requires that design have a "transversal" dimension. This can be achieved by including, in the early stages of process, constraints and parameters that are usually managed much later in traditional organizations. This study highlights the strong demand for design steering aiming at improving the quality of design and thus reducing the appearance of dysfunctions. With regard to this, we highlight the multidisciplinary characteristics as well as the predictive and reactive aspects of design steering in architecture. Then, based on existing cognitive models, we propose a model combining - in a simple way - three primary activities (analysis, proposition, evaluation). Then we enrich the model so that it covers the predictive and reactive aspects of design steering. This is done on the basis of our analysis of design steering, which allowed to uncover two narrowly linked entities. These two entities, which are generally implicit but are actually present in design projects, are: the problematic situation and the aimed situation. Finally, we specify and present the mock-up of a tool that is superior to the existing drawing, CAD, calculation or simulation tools. The tool that we present doesn't belong to the same "family". In fact, it can be called "reactive", which means that instead of allowing to define a solution, it allows to determine when the intervention pilot actor is needed
