Improve Support for RESTful Processing in JBossESB
Eliáš, Filip ; Kočí, Radek (referee) ; Letko, Zdeněk (advisor)
The goal of this work is to allow JBoss ESB to communicate with remote applications using REST. JBoss ESB is a platform that separates application logic from the process functions and enables communication between applications with different interfaces by sending messages. REST is an architecture that provides universal interface for communication between computer systems in the network. This work describes integration of REST communication architecture with JBoss ESB platform. The integration is divided into two parts. The input part accepts REST requests, propagates their content to the JBoss ESB and generates a response. The output part waits for the messages from JBoss ESB from which it creates the REST requests, sends them to the recipients and receives responses. The implementation puts emphasis on integration with the RESTEasy project. RESTEasy provides a framework that facilitates development of applications that support REST communication.

Design and Deployment of Information System for Management of Hardware
Eliáš, Filip ; Nguyen, Filip (referee) ; Neuwirth, Bernard (advisor)
This diploma thesis is focused at design and deployment of information system for management of hardware in Czech branch office of Red Hat. Design is based on analysis of current state, in which were revealed all flaws of current information system. Upon design of the information system, particular emphasis was placed on compliance of all requirements that should be met by information system. Part of the thesis is selection of appropriate method and process for deployment of information system.

Study of optimizing thermoinsulation properties of rigid polyurethane foams
Eliáš, Filip ; Vojtová, Lucy (referee) ; Petrůj, Jaroslav (advisor)
The thesis deals with the processes that occur in the course of the manufacturing of rigid polyurethane-polyisocyanurate (PU-PIR) foams, their properties and technology. It deals above all with principles of foam nucleation and stability. The purpose of understanding these principles is their possible use for improving thermo-insulating properties of the material. The experimental part of the thesis studies the influence of additives and ultrasound on the PU-PIR foam properties. It has been found that low molecular weight compounds with perfluorinated chain leads to decreasing foam cell size and its lower thermal conductivity. The additives mentioned act probably on the surfactants principle by facilitating nucleation and stabilizing growing centres of bubbles. They probably form also part of blowing agents mixture inside the foam cells which cause lowering of thermal conductivity as well. Compounds with similar chemical structure have unique influence on the properties of rigid PU-PIR foams. Further research ought to be focused on cheaper modes of producing perfluorinated compounds.

The Influence of Nanoparticles on The Properties of Hard Polyurethane Foams
Eliáš, Filip ; Kotlík, Josef (referee) ; Petrůj, Jaroslav (advisor)
The theoretical part of the thesis focuses on general principles of polyurethane chemistry. Nanotechnologies are also discussed, in particular using nanoparticles in the production of polyurethane foams. There are also mentioned selected preparation methods of silver and titanium dioxide nanoparticles. The experimental part describes mainly a novel method for synthesis of the concentrated solution of titanium dioxide nanoparticles in glycerol and their analysis by using confocal microscopy, scanning electron microscopy, dynamic light scattering and UV-VIS spectroscopy. Finally, there are suggested particular steps for further investigation of prepared nanoparticles for the production of rigid polyurethane foams, and also for other applications.
