A Framework for Dynamic Updating of Java-Based Applications
Genčúr, Martin ; Burget, Radek (referee) ; Rychlý, Marek (advisor)
This work concerns with dynamic evolution of applications written in Java. It investigates existing solutions implemented in both Java and other programming languages. Following part analyses complete substitution of object in running application in various situations. A framework for dynamic updating of Java-based applications is designed. The framework is implemented and is used in illustrative application. Finally, achieved results are evaluated and additional possible enhancements are stated.

Realisation of Service-Oriented Architecture: Web Services
Jiráček, Pavel ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
The main subject of this master thesis is the Service-Oriented Architecture (SOA). It shows a complete overview of Web Services in terms of realisation of a SOA. The thesis mentions what is already done and what else remains to ful ll the basic SOA principles. Then, it reviews Java EE platform tools used to deal with the Web Services. Next, it introduces the Java Management Extensions (JMX) technology as a solution of the web service's area - SOA governance. Moreover, it examinates the possible usage of JMX for the web service's management and monitoring issues. Finally, it implements an exemplary web services management and monitoring application on GlassFish server for testing purposes.

Web Server for Protein Interaction Searching
Halfar, Martin ; Očenášek, Pavel (referee) ; Burget, Radek (advisor)
Tato práce se zabývá zbůsoby, jimiž je možné získávat data z bioinformatických databází obsahujících data týkajících se interakcí mezi proteiny. Od souvislostí okolo vzniku bioinformatiky sloučením informatiky a biologie tato práce uvede čtenáře do problematiky přístupu k datům týkajících se interakcí mezi proteiny. Tato práce vysvětlí důvody vzniku IMEx konsorcia, jeho cíle a prostředky, kterými svých cílů dosahuje. IMEx konsorcium dalo vzniknout mnoha standardům, které usnadňují přístup k datům členů konsorcia a výměnu těchto dat mezi nimi. Jedním z výtvorů IMEx konsorcia je i webová služba PSICQUIC, která byla navržena s využitím architektonického stylu REST, a která je přístupná i pomocí protokolu SOAP. Obě tyto kategorie přístupů k webových službám jsou v rámci této práce studovány a na základě výsledků výzkumu je implementována aplikace pro získávání interakcí mezi proteiny z databází, jenž jsou členy IMEx konsorcia.

A Tool for Robustness Testing of Web-Services
Zelinka, Tomáš ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This project deals with testing of web services. The result of this work will be a tool for load testing of web services using fault injection in their communication. The first part of the project discusses the basic aspects of testing web services. The second part of the work is more focused on testing high loads in combination with fault injection. The tool will allow automated run of the tests. The distributed model of the tool was designed to simulate real loads. In the last chapter are summarized achieved results.

Usage of PDA for Distribution of Information in Closed Net
Ryšánek, Vojtěch ; Techet, Jiří (referee) ; Lukáš, Roman (advisor)
The task of this project is to build application for managing of multimedia data in enclosed wireless networks and to present this data to the user. In model case it can be for example city guide - on position given by GPS are presented information about surrounding scene. Application must be capable of downloading data into Pocket PC - PDA and present them to the user as user friendly application.

Transformation of Web Applications into Web Services
Zámečník, Miroslav ; Rychlý, Marek (referee) ; Weiss, Petr (advisor)
Present web is aiming to the possibility of automatization of user behavior on web applications. Adding of semantics and creation of web service interface are the main approaches for accomplishment of this user comfort. Nevertheless, this direction brings some problems which can make more difficult publishing and implementation of web documents. Web services can connect heterogeneous systems, because they are based on XML markup language that is a place where all applications can meet without lost of platform independence. The automatic transformation of a web application into a web service could be considerably more effective than to create a web service from the beginning. However, this step is for some applications almost unreal without knowledge of their inner structure. In most cases, the transformation will be done semiautomatically with help of human decisions.

A Tool for Testing of DPWS-Based Web-Services
Malášek, Vojtěch ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
The aim of this thesis is a design and implementation of tool for testing and monitoring of DPWS-based web-services. At first the thesis contains explanations of basic concepts related to Web Services, DPWS and used design patterns. Further the thesis contains the design and tool implementation description. The tool provides a client-side services implemented by Windows Communication Foundation, which communicates via the DPWS-based service. The service is implemented using .NET Micro Framework and can be run in the emulator in the integrated development environment. Obtained results and options for further extensions are mentioned in conclusion.

Fault Injection for Web-Services
Žouželka, Martin ; Očenášek, Pavel (referee) ; Rychlý, Marek (advisor)
This document is especially aimed at web services technologies and testing them using fault injection methods. The work deals with Service-Oriented Architecture, used as a standard for web service implementation, and with software testing in general. Practical part of the project includes the design and realization of a tool, which is able to test the most common types of web services according to setup criteria. To demonstrate its functionality, some of the sample and public web services were tested.

MANET Routing Protocol with Quality of Service Support
Vajsar, Pavel ; Medvecký, Martin (referee) ; Bečvář, Zdeněk (referee) ; Koton, Jaroslav (advisor)
The web and mobile web traffic is growing rapidly due to service accessibility in densely populated areas and massive usage of smart hand held devices (smartphones, pads and Internet dongles). This is a challenge for mobile operators and service providers, because it forces systematically increasing network throughput capacity and in parallel to keep this investment on profitable basis. On the other side, the user satisfaction with mobile broadband service should be considered as well, in order to balance the user expectations and mobile operator investments. Our work provides extensive QoE study for different conditions in sense of mobile web service, web content, network conditions and end user device. Finally, the obtained results create basis for more dimensional overview of mobile web QoE and allow to recognize quality and saturation thresholds based on network parameters. Further, obtained data provide base for design three prediction models for prediction of MOS (one for notebook, one for mobile device) and acceptability.

The Notes Information System Extention for Mobile Devices
Kallab, Vojtěch ; Ing. Jiří Peterka, Ph.D., MBA (referee) ; Dydowicz, Petr (advisor)
The main aim of this diploma´s thesis is the devise and the implementation of the extension of information system for mobile phones. The target is to make it easy to get the needed information even when the user is not present in the company and make recieving and working with information effective. In the first part there are described methods and processes which form the theoretical part of this thesis. The second part is related to the analysis of the current state of this company. This part is the basis for the third part which is the real devise for a new solution.
