The relation between latent toxoplasmosis and schizophrenia
Sglundová, Markéta ; Flegr, Jaroslav (advisor) ; Holub, David (referee)
The relation between the intracellular parasite Toxoplasma gondii and schizophrenia was studied and confirmed in several studies. There are proofs that latent toxoplasmosis deteriorates the course of schizophrenia. The goal of this study was to clarify whether there are differences between subjectively perceived quality of life of infected and non-infected psychiatric patients. We tested men and women from the PCP treated for the diagnosis of schizophrenia, who undertook serology blood tests for detection of anamnestic T. gondii antibodies. Patients also filled out two questionaires that assessed subjectively perceived quality of life - SOS-10 and WHOQOL-BREF. Patients filled out these questionaires twice, both at the start of the study before coming to psychiatric therapeutical institution and after one year. During the first testing were the questionaires filled out by 171 persons, after one year by 108 persons. Based on the results of these tests we found out that latent toxoplasmosis had a negative impact on subjectively perceived quality of life of schizophrenia patients, particularly on infected women. On the other hand, the quality of life of non-infected patients improved during one year. The effect of toxoplasmosis on quality of life was gender related, which could be explained by already...

3D Scene Reconstruction from Stereo Pictures
Turoňová, Beata ; Chum, Jaroslav (referee) ; Holub, Viliam (advisor)
We study 3D scene reconstruction from stereo pictures. First, we describe methods for computing fundamental matrix from a set of corresponding image points. Using this matrix we can obtain a projective 3D reconstruction. The second part deals with techniques of re ning the projective reconstruction to metric one. We focus especially on that one, which uses an essential matrix. Furthermore we discuss the possibilities of surface reconstruction from a given point cloud. The last part includes some details of an implementation and presents its results.

Creating Panoramic Images from Photographs Acquired with Different Camera Settings
Fibichr, Jaroslav ; Holub, Viliam (referee) ; Sedlář, Jiří (advisor)
When taking pictures for the purpose of creating panoramic images, it is more convenient to adjust camera settings for each image separately to keep the convenient brightness distribution. It usually leads to a set of images with differences in brightness must be corrected before stitching. The goal of this thesis is to propose solutions to adjust these differences and implement them in the application Panomedic. The first method is based on direct brightness level mapping in overlapping area of the images. The second method utilizes statistical values obtained from image brightness distribution. The method for searching the seam of stitching is also described. The resulting panorama image is without visible transitions between the input images.

Freedom as a basic human necessity and demand
Trojovská Drahovzalová, Jana ; Holub, Tomáš (advisor) ; Lorman, Jaroslav (referee)
10 RESUMÉ Bc. TROJOVSKÁ DRAHOVZALOVÁ, Jana. Charles University in Prague. Catholic Theological Faculty, 2008, Diploma Paper. Title: Freedom as a basic human necessity and demand The dissertation presents not traditional view of human freedom and its sense in different periods and cultures in four main chapters. It describes human freedom as a gift from the Creator; the freedom as a connection of true and responsibility. Then it is focused on human freedom as a demand which persists of all centuries and leads into the Universal Declaration of Human Rights. Finally, the work presents the Catholic view to human freedom with all consequences for the last fifty years. The thesis gathers mainly from historical resources but the last chapter is based on the latest statement of magisterium. The author used monographic and analytic-syntactical methods. The process is based on the comparison of information covered in books or empirical investigations. The work was created from the catholic view having respect to its use also between people without or with other religion. Key words: human freedom, human rights, responsibility, the true.

Studying the effect of the gap on the properties of laser butt welds
Holub, Matyáš ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
This thesis studies the impact of gaps on the properties of laser butt weld performed. For experiment was chosen DC01 ordinary steel and stainless steel X5CrNi18-10 (1.4301) with different thicknesses. The welding parameters depending on the gap between the welded plates remain constant. In the experimental part of the samples were welded using the Yb:YAG laser and compared to the tensile test, macrostructure, microstructure and Vickers hardness. At the end of the thesis are drawn experimental results.

Application for Monitoring System Resources of OS Windows
Holub, Ondřej ; Rozman, Jaroslav (referee) ; Grulich, Lukáš (advisor)
This bachelor's thesis deals with the monitoring principles of the system devices in the environment of the Microsoft Windows Operating System. The emphasis is placed on the system services and functions which are utilizable for the system resources monitoring. Some aspects related to their functioning are discussed and specified. The implementation part is represented by an application for the system monitoring based on these services and functions. The evaluation of the work and a possible extension is mentioned in the conclusion.

Control of special purpose machine tool
Plocek, Jaroslav ; Holub, Michal (referee) ; Houška, Pavel (advisor)
The master thesis treats the design of control system of special purpose machine tool. The first part analyzes and compares two possible variants of control system which use either a CNC control system Sinumerik or motion control system Simotion. Only the variant with the Simotion control system is subsequently examined in detail: its hardware configuration, the selection of components and partly also the software solution. The thesis further deals with the safety of the realized control system and of the whole machine. There are described general safety requirements of machinery based on harmonized European standards and their specific application in the design of safety functions and the safety circuits of solved machine tool.

Construction design hydraulic press brake
Stránský, Jaroslav ; Holub, Michal (referee) ; Pavlík, Jan (advisor)
This thesis is divided into several chapters. First two chapters after introduction are written as search type. In next part I devoted to detailed design of functional mechanisms of linearly moving parts of press brake. For the construction of stop mechanism I dealt with conversion types as ball screw, pinion with rack and timing belts. There is also quite thorough calculation part in ball screw and pinion with rack issue. I have also dealt with the necessary bending force and then designed hydraulic cylinders. Elaboration of machine frame with safety features is included.
