Experimental support for the development of specific integrated equipment
Hrbáček, Jiří ; Jegla, Zdeněk (referee) ; Kilkovský, Bohuslav (advisor)
Regenerative heat exchangers are used in a wide range of industries and in the technical equipment of buildings. These heat exchangers play an important role in saving thermal energy and removing volatile organic compounds from flue gases. The theoretical part of the work deals with the division of regenerative exchangers into rotary and switching exchangers and the possibilities of their use. These types of heat exchangers are used in many applications, e.g. as a heat exchanger using waste heat to preheat the process gas (regeneration layer), or as catalysts to accelerate the reaction required to remove volatile organic compounds (catalytic layer), or as integrated equipment where both the regeneration layer and the catalytic layer. The aim of the diploma thesis is experimental support in the development of a computer program for the design of a specific integrated device. The program allows the calculation of the regeneration and catalytic bed, or both beds simultaneously, i.e. integrated equipment. The diploma thesis deals with the support of a mathematical model for the calculation of the regeneration bed. Pressure loss and heat transfer play an important role in the selection and subsequent calculation of a suitable bed. To calculate them, it is possible to find more available computational relationships that differ significantly in their accuracy. It is therefore necessary to select the most suitable ones for the computational model. The practical part of the work then deals with research, analysis, and assessment of the suitability of methods used to calculate pressure losses based on a comparison with the values measured on experimental equipment. Subsequently, the work deals with computational methods for determining the heat transfer coefficient of the packed bed. A significant part of the practical part deals with the modification of the experimental equipment for the verification of computational relations for the determination of heat transfer with measured data.

Design of ventilation system in family house
Hrbáček, Jiří ; Toma, Róbert (referee) ; Pech, Ondřej (advisor)
The aim of this bachelor thesis is to design a ventilation system with recuperation in a family house. In the first chapter the work focuses on the research of ventilation units and their parts. Furthermore, the required amount of ventilation air is determined, and three ventilation units are selected. The duct route is then designed for the selected units and the pressure loss calculation is performed. In the final part the installation, operation and maintenance costs of the selected units are compared.

The Impact of Candidate Solution Mappings on Evolutionary Algorithm Efficiency
Hrbáček, Jiří ; Korček, Pavol (referee) ; Křivánek, Jan (advisor)
The Concern of the present study is summarizing knowledges in the theory of mapping candidate solutions , analysis and application of evolutionary algorithms. The study provides summary of the evolutionary algorithms, classification and application. The target of the study is links gained knowledge from sectionS of ; evolutionary algorithms, mapping candidate solutions and creations of a system that will demonstrate and influence mapping the efficiency of the evolutionary algorithms succesfully.

Competence of non-medical staff in the Czech republic
Hrbáček, Jiří ; Bruthans, Jan (advisor) ; Prošková, Eva (referee)
The topic of the diploma thesis is dedicated to competence of non medical staff in the Czech Republic. The whole draft is built on analysing of the specific issues and consideration if it is possible to attein, that physicians could transmit part of their competences to non medical staff under the current law approval. In the theoretical part of the work I focus on identification of individual factors influence the work of non-medical staff and the conditions under which it is possible to perform the medical profession. Further on the system of education and competence individual profession primarily workers in intensive care. It also includes considerations for and against increasing the skills and vicarious view of selected experts. At the end of the thesis I developed a comparison between the neighboring states and the Czech Republic in the competence of selected professions. In the empirical part of the work, I work with data that I received from questionnaires. I concentrated mainly on nurses in intensive care units, and anesthesiology and resuscitation department. As well as to sites of paramedics station services in Prague (CSU crew III) Research questions aim to confirm or refute the hypotheses that I set on, if they want or not paramedical refuse the extension of his powers and at the same...
