The Influence of Passive Safety Features During Vehicle Collisions with Pedestrians
Mrázek, Jan ; Vémola, Aleš (referee) ; Tokař, Stanislav (advisor)
This thesis deals with the influence of passive safety features during vehicle collisions with pedestrians. The first part focuses on introducing the basic components of active and passive vehicle safety. The second part deals with construction and usage of modern components of passive safety during vehicle collisions with pedestrians. A comparing situation model of vehicle collisions with pedestrian is introduced in the third part for which a simulation programme has been used. At the close of this part there is a result synthesis of these model situations. The last part deals with the possibility of increasing pedestrian safety.

Assessment of a selected part of the water supply network
Mrázek, Jan ; Dvořák,, Pavel (referee) ; Raclavský, Jaroslav (advisor)
The aim of this thesis is to research the field of water distribution system monitoring and modeling such system. In the next section the thesis describes a part of the water distribution system which is located in Pardubice district, specifically south of town Přelouč. With knowledge from the done research a hydraulic model will be done. This model made in EPANET interface will be calibrated and verified using data, which was acquired by the administrator of the system VAK Pardubice a.s. Afterwards new pipelines will be added to simulate the future situation accordingly to the area plans of the cencerned towns. Furthermore another aim is to simulate the requirements made towards the water distribution system in the future in case all the areas in area plan will be completely used. This will result into creation of forward looking hydraulic model which will show possible weaknesses of the water distribution system. In case of any shortcomings, according measures will be designed for future use.

Rainfall data in urban drainage
Mrázek, Jan ; Prax,, Petr (referee) ; Raclavský, Jaroslav (advisor)
The aim of the bachelor thesis is to process knowledge from measured precipitation data and aplicating this knowledge on methods of prepration of a hydraulic sewage network model of Znojmo city. The first part is a research in the field of interest, being sewage network and precipitation data processing. The detailed procedure of modeling and quantification of the measured data is explained in the practical part of the thesis. After that the process of inputting the data in to a hydraulic model in MIKE URBAN, the program which draws topological data from GIS (retained by VAS a.s. as the investor) and exports the final model into a SWMM enviroment. At last but not least the thesis focuses on schematization of the objects situated on the sewage network, such as relief chambers. The result is a noncalibrated and nonverified model of a part of sewage system of the Znojmo city and systematically organized measured critical rains. This model is going to be optimized after this thesis is finished, thus also calibrated and verified.

Sol-gel synthesis of ternary ZnxTiyOz nanostructures for applications in solar cell technologies and photonics
Mrázek, Jan ; Nižňanský, Daniel (advisor) ; Pinkas, Jiří (referee) ; Pollert, Emil (referee)
The presented study deals with the sol-gel synthesis of nanocrystalline ternary phases of the general formula ZnxTiyOz, their characterization and potential application in photonics. Achieved results brings new fundamental knowledge about the processes leading to the formation of ZnxTiyOz nanocrystals from amorphous xerogels and gives novel information about structural and opto-electrical properties of prepared materials. Based on the presented results, most of all up-to-date reported ZnxTiyOz compounds with tailored nanocrystalline size and structure can be prepared as powders or thin films. Two sol-gel approaches based on the cluster process and direct heteronucleation were employed to prepare initial sol. Sols were optionally doped by Eu3+ ions to evaluate the effects of rare earth element to crystallization properties of formed compounds. In the first part of our study crystallization properties and structural evolution of thermally treated xerogels were analyzed. As a result a versatile method allowing the preparation of inverse spinel Zn2TiO4, cubic defect spinel ZnTiO3 and rhombohedral ZnTiO3 with tailored nanocrystal sizes was established. Initial composition and thermal annealing allow us to prepare selected ternary phase with tailored nanocrystal size ranging from tens of nanometers up to...

Investment instruments
Mrázek, Jan ; Pokorný, Jan (advisor) ; Hraba, Zdeněk (referee)
1 Abstract Title of the thesis: Investment instruments The main purpose of this thesis is to analyze various investment instruments, their markets and their feasibility as an alternative to saving products. Secondary purpose of this thesis is to define a model investor, create reasonable and fitting investment strategy for them and introduce examples of investment portfolios that fulfill the strategy. The thesis is divided into two main chapters, each of which analyzes investment instruments from different perspectives. Chapter One introduces the instruments in general and describes their key characteristics, their legal regulation and brief history. One subchapter is dedicated to explaining motives driving the participants of financial markets. Another subchapter categorizes the investment instruments and divides them into distinct groups. Last subchapter investigates the financial markets themselves and describes their types, structure and functions. Chapter Two introduces a model investor and describes their particular motives for investing. Two subchapters analyze historical development of selected instruments and saving products and then compare the results. In the last subchapter assumptions are made about various products' feasibility for the model investor. Specific investment strategy for the model...

Truth and theatre
Mrázek, Jan ; Hogenová, Anna (advisor) ; Jirásková, Věra (referee)
The topic of this bachelor thesis Truth and Theatre is the study of the truth by connecting the concepts of the phenomenologist Jan Patočka and the theatre director and researcher Jerzy Grotowski. The objective of this thesis is to capture the factual connection between these two concepts. This work reveals how the topic of the truth tied with the ancient abstract meaning of aletheia - "unconcealedness" is being manifested in the theatre, how it is related to the themes of myth, ritual, situation, corporality, education and why is this understanding of truth inseparable from the action, self-awareness and the moral. The aim of this work is also to map the philosophical basis for the master's thesis, which will be created at the Department of Drama in Education on DAMU. KEYWORDS Jan Patočka, Jerzy Grotowski, Martin Heidegger, truth, aletheia, phenomenology, theatre, performer, action, knowledge, myth, dramatic education, care for the soul, paratheatre

Authentic Man Jan Patočka
Mrázek, Jan ; MARUŠÁK, Radek (advisor) ; ČERNÍK, Roman (referee)
This work is a description of the realization of a pedagogical project that uses the method of drama in teaching philosophy. It's themes are the truth, authenticity and Charter 77, with focus on the personality and work of Jan Patočka. It is divided into a theoretical and practical part. The theoretical part presents the creation of the project, the preparation of the realization, the philosophical starting points and also the analysis of the methodology of drama in philosophy. In the practical part, the realization of the project is being described, with notes on the fulfillment or non-fulfillment of the starting points from the theoretical part. The key method of the work is reflection. It is set between pedagogy, philosophy and theater and aims to draw methodological conclusions from the implementation of the project. These conclusions are based on pedagogical and philosophical assumptions. This work may be an inspiration for pedagogues dealing with the combination of drama and other disciplines in teaching or for educators seeking the philosophical foundations of their work.
