Holubička, Pavel ; Pinkas, Otakar (advisor) ; Šmejkal, Ivo (referee)
The main aim of this work is to describe the gradual building, exploitation, and dissemination of specific enterprise computer network in the Czech company VHL Ltd. The pivotal challenge was not only write down the process, but in practice also the extension of the network by server, the wireless segment, and the connection of two remote computer networks with reference not only to functionality, but also for safety. To achieve the results it was therefore necessary to combine theory with practice. Individual work procedures have been tried, tested and evaluated. In the negative results the whole process had to be repeated several times so. In the bachelor's thesis, there are many instructions on what to do in setting up individual network services as well as ensure their security. The first chapter deals with the theoretical knowledge about LAN and WLAN networks. More closely are describe various standards, network elements and their characteristics, and provided services. The second examines the evolution from the beginnings to the present network. More detailed is describe the enlarging of the wireless network, its construction, security, and testing. The point of third chapter is to give overall view of the extension by network server. It describes the choice of hardware with using multicriterial selection, and the selection, evaluation and installation of the operating system. Subsequently, it deals with hardware and software security of the server and with connection of the remote networks through VPN instrument. In conclusion, there are attended a few words to the potential innovation.

Validation of atmosphere prediction model in meso-scale
Mejstřík, Tomáš ; Žák, Michal (advisor) ; Řezáčová, Daniela (referee)
In this thesis, we are aimed at various physical principles of convective parametrization. First, traditional parametrization schemes are described. This schemes are based on hypothesis of quasi-equilibrium between large-scale processes and convective activity and suggestion about negligible mesh fraction of convection in grid-box. But, passing to resolution in the range below 10 km, the deep convection si partly subgrid, partly resolved. A new generation of prediction with high horizontal resolution is now introduced. This model has new prognostic convective scheme with new description of interaction between convective mass transport and microphysical computation of clouds and precipitation. A prognostic scheme has been used for the vertical velocity of udraft and downdraft and more elaborate microphysics, include effect of autoconversion, evaporation and sedimentation of precipitation. These models are expected to forecast many atmospheric events much more precisely (e.g. strong convection). Validation of model in experiments at different resolutions is the main task of this work. Comparsion of new developed model with model currently used, sensitivity study of new components, are presented.

Using dataloggers in physics teaching (focused on Vernier experimental system)
Kácovský, Petr ; Böhm, Pavel (advisor) ; Drozd, Zdeněk (referee)
Title: Using dataloggers in physics teaching (focused on Vernier experimental system) Author: Petr Kácovský Department: Department of Physics Education Supervisor: Mgr. Pavel Böhm Supervisor's e-mail address: pavel.bohm@mff.cuni.cz Abstract: Modernizing equipment enables schools to involve advanced computer- aided systems in physics teaching. This work especially focuses on systems capable of recording and storing measured data for later evaluation - the dataloggers. The introduction of this work is devoted to a survey among physics teachers that should investigate what form of instructions they prefer; then a brief search of existing ma- terials follows. The main part of the work consists of newly created instructions for experiments with dataloggers of the Vernier experimental system, primarily designed to serve tea- chers to implement physics experiments in their teaching. The instructions always include a description how to prepare and undertake the measurement, how to process the measured data and what questions and tasks for students can be connected with this part of physics. Experiments described in this work mainly focus on secondary school thermodynamics (or more precisely on molecular physics and thermals) and their thematic intersection is energy, its forms, transmission and conservation.

Some aspects of calculating solvency of insurance companies according to the principles of Solvency II
Hradecký, Ondřej ; Janeček, Martin (advisor) ; Černý, Michal (referee)
The diploma thesis focuses on the topic of the future regulatory regime of the insurance and reinsurance market of the European Union called Solvency II. Currently the most discussed issue without a final structure is an extensive set of legislative and technical changes not only in the area of solvency treatment. Primarily, the work focuses on the standard formula calculation of capital requirements that reflect the solvency position of companies on the market. The first part deals with the theoretical description of the calculating methods of the required capital levels under current and future rules on the basis of available official documents. Further the general overview of the Solvency II is presented, a more detailed description of the valuation techniques of balance sheet items for the purposes of Solvency II, dealing with company's own funds and possible ways to optimize the asset portfolio are also included. Some theoretical descriptions of computational procedures applied on a fictitious life insurance company are presented in the second, more practical part of the diploma thesis.

Probabilistic Models and Methods for the Analysis of Sports Results
Rambousková, Daniela ; Saxl, Ivan (referee) ; Volf, Petr (advisor)
The statistical modelling on a sports field is in the process of a great development. Sports clubs have gradually changed into commercial companies and thus many possibilities how to take advantages of statistical instruments have emerged. Undoubtedly, the most popular task is the prediction of possible future results. The first part of this thesis summarizes the most interesting methods and types of solutions that were developed primarily for football matches. In this case the Poissons' regression models are mainly used. However, when the influences of time are taken into consideration, these models become more difficult and complicated for computations. The second part deals with the statistical survival analysis and random point processes and tries to find its utilization and connection with the predictions of the results of sports matches. On the basis of the Cox' regression model, a simple model for ice-hockey matches is derived here. This model estimates offensive and defensive forces of every team and other influences, for instance power plays and home environment. It describes the match as a random point process, where the time of scoring represents its random points. The model is applied on the data obtained from the first thirteen rounds of the Czech National Ice-hockey League and the received...

The great tit (\kur{Parus major}) as a model species in spatialy cognitive tasks
NÁCAR, David
In this thesis the spatial cognitive experiment with great tits (Parus major) as a model species is described. In this experiment tits learnt to respond to one of four response keys according the presented stimuli. Two types of stimuli were used: one of them contained configural information about response keys, but the other didn´t. The experiment tested the difference of using these two types of spatial information in great tits in two experimental designs. In the first design stimuli were presented in computer screen, in the other they were presented in the floor of experimental chamber. The thesis then discusses the performance of tits in two types of stimuli and two versions of experimental design and compares these results with pigeons in similar experiment.

From machine to icon:car in popculture from the 60s
Rybář, Václav ; Bednařík, Petr (advisor) ; Jirák, Jan (referee)
An automobile is one of the most important phenomenons of modern technology. Since its origins, it has profoundly shaped our physical, economic, politic, social, cultural and media habitat. The objective of this Master thesis is to analyze the evolution of the role of the car in the popculture from the 60s onwards and its dimensions, with a primary focus on Anglosaxon culture, with excursions to Asia and continental Europe, primarily Czechoslovakia/Czech Republic. The core foundation of the thesis lies in the analysis of the popcultural genres, selected films, TV series, computer games and comic books. The main purpose of the thesis is to reflect upon the identity and conceptual shifts of car, going from a mere transport machine through a vehicle of product placement towards the concept of the icon, a narrative hero of popculture. The hypothesis to verify is that the car has become an essential part of the popculture itself, reflected in many various dimensions: car as a toy, car as a friend, car as a status symbol, car as a narrative extension of the hero and finally, car as a hero and subject. The thesis is divided into five separate chapters, all including case studies. Following an introduction summarizing cultural, economic and historic factors of the car industry, the first chapter describes...
