Reconstruction of Data Types for Decompilation
Matula, Peter ; Ďurfina, Lukáš (referee) ; Křoustek, Jakub (advisor)
This document describes methods for a reconstruction of data types in the decompilation problem. It defines the concept of reverse engineering and introduces decompiler developed by the Lissom project. It presents existing methods of reconstruction of the simple and complex data types, and explains in detail approaches based on data-flow analysis and analysis of the memory operation offsets. The core of this thesis is the design of a new technique of reconstructing simple and complex data types, suitable for deployment in a retargetable decompiler environment of the Lissom project. Basic principles of the new technique, its implementation and related changes in decompiler and intermediate language are described. The solution is tested and the conclusion discusses the achievements, shortcomings and direction of the further work.

Monitoring of hazardous environment
Bilík, Martin ; Blecha, Radim (referee) ; Blecha, Petr (advisor)
Diploma thesis Monitoring of hazardous environment deals with possibilities of construction of monitoring device for the nuclear power station Temelín. In the first part are accurate requirements for monitoring device, individual risks and identify obstacles and opportunities how to overcome them. There is also description of basic options for measuring temperature and environmental monitoring. Using multi-criteria analysis was done the selection of all components, from which is possibility to construct the first development release of monitoring device. 3D models for each component and the overall design visualization facilities were created in the programming environment of Autodesk Inventor. The conclusion provides an overview of the financial cost of the equipment is assembled

Comparative Analysis of Chemistry Education ( Czech Republic - Scotland)
Laburdová, Jiřina ; Klímová, Helena (advisor) ; Teplý, Pavel (referee)
Key words: Scotland, Czech Republic, education system, Chemistry education, Chemistry teaching, National Qualifications, Standard Grade, Intermediate, Higher, Advanced Higher Abstract: The education system in the Czech Republic is currently undergoing many changes. Education systems of foreign countries are often what inspire us to make these changes. The aim of this thesis is to describe the education system in Scotland and the way chemistry is being taught at secondary schools in this country. Further it tries to compare these to the education system and chemistry teaching in the Czech Republic and consider whether we can adopt any aspects of Scottish education. Apart from analysis of study plans and educational documents, research for this thesis included visits to chemistry lessons at three secondary schools in Scotland and interviews with teachers at these schools. In the text, cultural and historical context of Scotland related to the education system is mentioned briefly. Then the Scottish education system is explained and Chemistry teaching at secondary schools is described from the point of study plans and requirements. The following chapter contains a description of schools that have been visited, together with reports from selected chemistry lessons. Last chapter then compares various aspects of...

Isolation and characterisation of light harvesting complexes from bacteria of the genus Gemmatimonas
DACHEV, Marko
Photosynthetic bacteria are highly abundant. The isolation and characterization of the light-harvesting complex from the Gemmatimonas phototrophica AP64T which belongs to the seventh phylum of the evolutionary important (bacterio)chlorophyll-containing bacteria are reported here. The purification of the complex was achieved by gel-filtration and electrophoresis. HPLC was used for identification of the pigments. The protein subunits were further identified by MS analysis.

L'analyse expérimentale des paramtres dynamiques du rail grille
Podolník, Adam ; Tomandl, Vladimír (referee) ; Smutný, Jaroslav (advisor)
In terms of deciding on the appropriate use of the railway superstructure assemblies in both the recommendations arising from the theoretical analysis (modeling), as well as recommendations obtained under static and dynamic testing of the finished product play an important role. Such tests can then be applied in the laboratory or in the field. The thesis will be devoted to operational testing of selected track grid structures in situ. For measurement purposes an appropriate measuring point will be chosen and the methodology of measurement will be proposed. In terms of track geometry sections in curves will be selected. On the basis of tests carried out dynamic parameters of structures will be determined. To their evaluation suitable mathematical system will be chosen. It assumes the use of mathematical methods in time and frequency areas. In the thesis there will also be a comparison of the parameters of the tested structures. Based on the measurements it will be a source of recommendations for the practice.

Design of delta pi 3D printer with tempered bed using CAE systems
Koudela, Ondřej ; Maxa, Jiří (referee) ; Vyroubal, Petr (advisor)
This master's thesis deals with 3D printing using non-commercial 3D RepRap type printers. This work briefly describes development trends of non-commercial RepRap printers, theory of FDM print with analysis and comparison of materials, which are used in printing and the issue of the finite volume method and theory of heat diffusion. The practical part based on simulations from SolidWorks Flow Simulation discussed two basic methods of heating hot bed, then the temperature profile of hot end and the heat flow in full assembly of the printer. Outcome of this work is design an optimized model and the physical assembly of 3D printer delta pi type.

Assembled Steel Tanks
Konečný, Jiří ; Hrstka, Miroslav (referee) ; Marcián, Petr (advisor)
This thesis deals with the area of bolted steel tanks, which constitute a significant share of the total number of tanks of all types of tanks. In the first part of this thesis is mentioned short history of bolted steel tanks, tanks producers and major standards and standards governing the calculation and realization not only these tanks. In the next part of this thesis mentions the various segments and major parts of bolted steel tanks. This is followed by a short description of the assembling. The last section describes the creation of a computer model of roofs used in simulation program ANSYS and subsequently performed stress-strain analysis for snow loads according to various snow areas for different FEM model in the 2D and 3D levels.

Sensitivy analysis of the influence of manufacturing inaccuracies on the nuclear fuel reactivity
Sedlák, Martin ; Katovský, Karel (referee) ; Novotný, Filip (advisor)
This thesis deals with a sensitivity analysis of the influence of manufacturing inaccuracies on the reactivity of nuclear fuel. Sensitivity analysis has been done for fuel assembly TVSA-T, for nuclear reactors VVER-1000. Particularly, for fuel rod of type tvel - without burnable absorbers. Thirty three combinations of maximal and minimal of manufacturing parameters were simulated in SCALE environment. Changes of multiplication coefficient in dependence on burnup for 5 combinations have been also studied. It has been found that the most significant influence on the reactivity has the accuracy of enrichment and outer diameter of cladding. It has also been found that influence of manufacturing inaccuracies is not constant during burnup. The benefit of the thesis is determining the effects of individual inaccuracies on the reactivity and the fact that their influence is not constant during burnup.

Childlessness in relationship to the family behavior in the Czech Republic
Hon, Filip ; Langhamrová, Jitka (advisor) ; Miskolczi, Martina (referee)
This Bachelor thesis analyzes the childlessness, some other selected indicators related to the family behavior in the Czech lands and their context in the various historical stages. Its main objective is to assemble a compilation of census data about childlessness from 1930 in age groups, which is not available anywhere. At the beginning there is a chapter devoted to theoretical matters, followed by the analysis of the selected periods. At first, there is analyzed the first half of the twentieth-century, at least for the years where data are available. This chapter is finished by population census in 1950, because since then it do not cause too many effects of WWII on demographic behavior and are beginning to rather show effects of the new socialist state system, which are described in the following chapter. The last chapter is devoted to the period from the Velvet Revolution to the data, which was the latest available when this thesis was written.
