The aim of this thesis is the analysis of selected frameworks for the development of modern web applications on the Java platform focusing on the front-end. The work is complemented by well-chosen source code examples that help the reader to create one's own view of the frameworks and it can also server as a tutorial. Introductory section focuses on the trends of modern web applications, especially on the front-end. It affects themes such as support for mobile devices, AJAX or responsive design of user interface. There are also introduced the latest technology on the front-end including HTML5, CSS3, jQuery library and dynamic language LESS whose main objective is the simplification, shortening and making cascading style sheets more dynamic. The output of this section: General LESS template is freely available and it can be applied to emerging projects. For the analysis there has been created static registration form on which there are applied frameworks Apache Wicket and Spring MVC with template engine Freemarker. In terms of analysis were chosen following points: the basic structure of the project, the application of static templates, external JavaScript / jQuery library, internalization, application of the form, submitting the form and validation of the input fields. The points were discussed in detail, especially in terms of implementation of both analysed frameworks. The outputs of the analysis are freely available structures of the projects and both of the resulting applications.

This master's thesis deals with data mining techniques and classification of the data into specified categories. The goal of this thesis is to implement a web portal for administration and classification of data from distributed sources. To achieve the goal, it is necessary to test different methods and find the most appropriate one for web articles classification. From the results obtained, there will be developed an automated application for downloading and classification of data from different sources, which would ultimately be able to substitute a user, who would process all the tasks manually.

Das World Wide Web befindet sich im Wandel von interaktiven Webseiten hin zu Web- Applikationen. Eine steigende Zahl von Anwendern führt täglich Aufgaben ausschließlich mit Hilfe des Web-Browsers durch. Dadurch wird das Web zu einer bedeutenden Plattform für Anwendungsentwicklung. Dieser Plattform fehlt jedoch heute noch die Rechenleistung nativer Applikationen. Microsoft Xax und Google Native Client (NaCl) sind zwei neue, unabhängige Technologien zur Entwicklung nativer Web-Applikationen. Sie ermöglichen die Erweiterung herkömmlicher Web-Applikationen durch kompilierten nativen und dennoch betriebssystemunabhängigen Programmcode. Die vorliegende Dissertation untersucht die Vor- und Nachteile nativer Web-Applikationen und analysiert zudem das tatsächliche Leistungsvermögen im Vergleich zu konventionellen JavaScript Web-Applikationen. Dazu wird eine experimentelle Leistungsanalyse von nativen Applikationen in C, JavaScript Web-Applikationen und NaCl nativen Web-Applikationen anhand vier unterschiedlicher Vergleichstests durchgeführt. Dabei werden die folgenden Leistungsaspekte betrachtet: mathematische Operationen (seriell und parallel), 3D-Grafikoperationen und Datenverarbeitung. Die Ergebnisse der Leistungsanalyse zeigen, dass NaCl Stärken in mathematischen und 3D-Grafikoperationen zu Grunde liegen, jedoch erhebliche Schwächen bei der Datenverarbeitung aufweist. Entsprechende Lösungsansätze zur Optimierung der Anwendung werden erarbeitet und erörtert. Eine Bewertung anhand technischer und nicht-technischer Kriterien komplementiert die Ergebnisse der Leistungsanalyse. Darüber hinaus werden die technischen, politischen und strategischen Treiber für NaCls Marktdurchdringung diskutiert. / The World Wide Web is amidst a transition from interactive websites to web applications. An increasing number of users perform their daily computing tasks entirely within the web browser, turning the Web into an important platform for application development. The Web as a platform, however, lacks the computational performance of native applications. This problem has motivated the inception of Microsoft Xax and Google Native Client (NaCl), two independent projects that facilitate the development of native web applications. These allow the extension of conventional web applications with compiled native code, while maintaining operating system portability. This dissertation determines the benefits and drawbacks of native web applications. It also examines the actual performance capabilities of JavaScript web applications. An experimental performance analysis is undertaken in order to determine and compare the performance characteristics of native C applications, JavaScript web applications, and NaCl native web applications. Four application benchmarks consider different performance aspects: number crunching (serial and parallel), 3D graphics performance, and data processing. The results confirm that NaCl''s performance in computational tasks and 3D graphics is impeccable. On the other hand, it shows substantial limitations in data processing. These are evaluated and possible solutions are discussed. The results of the performance analysis are complemented with an evaluation on the basis of technical and non-technical criteria and a discussion of the technical, political, and strategic drivers for NaCl.

Today there are a big need for a system that delivers overview of all available units for different municipalities and shipping- and security companies due to the increasing requirements for efficiency. The purpose with this graduation thesis is to find out which systems that is suitable to use while developing cost-effective software for positioning and to produce a prototype for such solution. This assignment has been done at the request of PocketMobile Communications AB. PocketMobile is a company that are specialized on delivering modern mobile software solutions and systems to companies with their own vehicle fleet or mobile workers. This master thesis can be split into two separate parts, the theoretic- and the practical part. The theoretic part includes producing a number of functional requirements in cooperation with PocketMobile and comparing the available systems against the function requirements. The practical part deal with the development of a prototype that demonstrates the software recommended. The development tools that best matched the functionality requirements when the selection was made in May 2007 were Map24 and OpenLayers. The system that was selected to use while developing the prototype was Map24, because this product matches all of the requirements and it is also suited for professional usage regarding support, scalability and reliability. Map24 also have some advanced functions like ability to route plan for example. The prototype that has been developed is web based and the graphic design is similar to Google Maps.
