Transmission system of the Czech Republic with the respect to the european critical infrastructure
Mádr, Lukáš ; Bílek, Martin (advisor) ; Háva, Petr (referee)
The diploma thesis deals with security status of the transmission system within the Czech Republic. The paper reflects upon the character of the transmission system in the context of European critical infrastructure, as well as its position within the system of power supplying. It defines elements of both Czech and European critical infrastructure, and provides résumé of threats that could endanger or even destroy these elements. By employing quantitative risk analysis, as well as other methods, the text is trying to answer the question whether the Czech transmission system is currently dealing with any real threats. It also compares various kinds of approaches to securing of the critical infrastructure with regard to interests of variety of actors, and positions the selected EU member states hold. The whole concept is evaluated from the view of energy security, with an emphasis on network structure whose role in this concept is concerned essential by the thesis, especially insofar as the future is concerned.

Interactive flexible program - Sulfur chemistry and its impact to acquiring of curriculum
Dvořák, Michal ; Čipera, Jan (advisor) ; Bílek, Martin (referee) ; Havlíček, David (referee)
13. Summary At the end I have found out that all the main and partial goals identified at the beginning of the work have been fulfilled and the stated hypothesis has been confirmed. The results of the educational material analysis show that there is no any satisfactory complex educational program on the market. The questionnaire investigation between teachers and pupils acknowledged the present trend of using computers in education. It was explicitly demonstrated the interest at the both side oť the utilization in education system. The most of teachers appreciate the possibility to edit the Program according to the current needs. The chosen technology DHTML allows any user with the basic computer literacy and at least elementary knowledge of HTML to modify and adjust the Program in compliance with the actual conditions. On the basis of the facts established by enquiry I have created the Interactive Flexible Program "Chemistry of Sulfur" in order to all requirements on the modern didactic instrument specified for self-study. I have verified the created IFp during the study on some secondary schools in the Czech Republic. The results proofed the main research hypothesis of this work that the self-study with IFP contributes to the better results within learning of chernistry. I only did not succeed in the...

Feedback procedures, its options and limits in practical training of future chemistry teachers
Hladíková, Dana ; Beneš, Pavel (advisor) ; Dvořáček, Jiří (referee) ; Bílek, Martin (referee)
Present days mean rapid development of technologies and their use in various spheres of science, research, production etc. This paper shows possibilities of using video technology in teaching during the pedagogical training of future chemistry teachers, with appropriate feedback. Terms reflection and self-reflection of teacher's skills, diagnostics and autodiagnostics of pedagogical activities, monitoring of pedagogical skills etc. represent in fact processes connected with application of feedback principles during the pedagogical training. In practice-oriented parts of teaching preparation, these processes are considered to be substantial to increase the effectiveness. Students' opinions shall also have a significant place in post-inspection procedures. Key words: video technology, feedback processes, reflection, self-reflection, diagnostics, autodiagnostics, monitoring of professional skills, inspection of classes, work practice. 6

Optimization of a sinusoidal pump
Sluše, Jan ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of the diploma thesis is to design the technical solution of minimization of frictional losses, which occur when using a sine pump at position of the shaft locking and on the impeller wheel. The losses originating from the frictional forces have a negative influence on the lifetime of individual parts and economy of the pump. In the first part the author describes sine pumps from the constructional point of view and the main producers are mentioned. The second part contains suggestions on the parameters of the pump and various possibilities of solutions. The last part covers the experiment and conclusions.

Optimization of vortex pump
Šmíd, Pavel ; Bílek, Martin (referee) ; Pochylý, František (advisor)
The aim of this labor is to optimize the vortex pump. When this pump should find application on the field of health like human heart for extracorporeal circulation. We will deal with the analysis of shear stress in the pump and its size of it and consider the use nonwetting surfaces to reduce the shear stress values. All our analysis will be made by CFD calculations.

Modeling of flow in ejector
Bílek, Martin ; Habán, Vladimír (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis deals with the flow modelling in the ejector using the FLUENT software. It develops a diploma thesis created in the past, where a mathematical flow model in the ejector was created and experimentally tested. The aim of this work is to analyze the ejector calculations and to model a flow in an ejector of the same shape as in the experiment and under the same conditions, too. Another objective was to assess the influence of the throat length and to examine if the pressure in the ejector mixing chamber remains constant. Finally, the disagreement between the experimental figures and the ones gained from the mathematical model of the ejector are discussed.

Business Plan
Bilek, Martin ; Srpová, Jitka (advisor) ; Mísař, Jan (referee)
The subject of my master thesis is creating a business plan. The theoretical part deals with the characteristics of business plan in its individual chapters. In each of these chapters I summarize and evaluate the theoretical methods that can be applied on the given area. The practical part deals with preparation of a business plan focused on cloud computing for small and medium-sized enterprises.
