Road-accident investigation and evaluation critical places on urban area Brna
Holoubek, Vladimír ; Mika, Otakar Jiří (referee) ; Mašek, Ivan (advisor)
At first, the work focuses on the statical description of the condition of the highway and railway system in Brno and the South Moravian region. Above all, it focuses on the statistics of the accident frequency, the intensity of transportation and the trucking traffic flows. In its analytical parts, it computes, from the available statical datas and the condition of highways, frequent sections of the accident frequency, dangerous places and the most used routes of the freights of dangerous chemical substances and detergents. The work evaluates the jeopardy for the inhabitants and the environment.

Modellling Consequences of Chemical Accidents
Kaup, Aleš ; Fleisig,, Petr (referee) ; Mika, Otakar Jiří (advisor)
Nowadays the number of produced chemicals is increasing very rapidly. However, technological processes are gradually improving and safety of handling chemicals is increasing. Unfortunately, even today, chemical accidents can happen. To alleviate results or to prepare for protection of humans, extensive knowledge is necessary to estimate the course of a chemical accident. One of the means of accident mitigation are modern modelling programs that will help us to clarify the implications and consequences of the course of chemical accidents. Based on the results of such modelling, different organizational and safety measures (preventive, oppressive, protective, rescue and relief character) can be taken to increase readiness for disasters and especially to reduce vulnerability of population.

Extraction Detoxification of Sensitive Components
Andrle, Marek ; Vávrová, Milada (referee) ; Mika, Otakar Jiří (referee) ; Skoumal, Miroslav (referee) ; Čáslavský, Josef (advisor)
Solvent extraction is one of the methods available for the decontamination of sensitive equipments that are contaminated with chemical warfare agents. The efficiency of extraction method have been verified on the samples, (steel or rubber) that have been contaminated with drops of mustard gas. These samples have been inserted into the extraction flow cell through which solvent (ethoxynonafluorobutane - HFE-7200) flowed. The solvent was sampled in the time intervals. These samples of solvent were analysed for the concentration of mustard gas. Process of extraction was monitored for the three operational factors (the solvent flow rate, temperature and the ultrasound power) and for three different situations (dissolution of drops of mustard gas, mustard gas desorption from the structure of the sample and dissolve drops of mustard gas with the subsequent desorption from the sample). The development of the decontamination process in time was found to consist of two stages. In the first stage the rapid dissolution of the liquid part of mustard gas in a solvent and in the second phase was such as mustard desorption from the structure of the sample and this phase was considerably slower. Extraction is to accelerate increasing the value of the flow of the solvent, the temperature and the performance of the ultrasound. These operational fac-tors have a significant impact on the thickness of the laminar layer of solvent, the solvent replacement coefficient in a cell, diffusion parameters in the process, the viscosity, the solubility of mustard gas in a solvent and the maximum achievable concentration of mustard gas in the rubber sample. The values of adjustable parameters was obtained by mathematical analysis of mathematical model. The progress of extraction under different operational conditions can be predicted by these parameters. The effect of solvents and ultrasound was experimentally verified for selected equipments of computing and communication technology. The possibility of separation of chemical warfare agents from the solvent was verified too.

Emergency Plan for a Shopping Centre for the Protection of Persons Against Deliberately Set Traps Involving Explosive Devices of Hazardous Chemical Substances
Venclovský, Filip ; Kirsch, Libor (referee) ; Mika, Otakar Jiří (advisor)
This theses is speaking about the posibilities of commit a terrorist action through the agency of the dangerous chemical substances or explosive devices in the Czech Republics shopping centers. Teoretical part wants to give an informations about legislative base of this dilema, characteristic of the shopping centers, characteristic of the disposable resources to the perpetration the terrorist action and the instruments for the solution of theses expectional events. The unique survey is base of practical parts. The survey was carry out to the fading out the best possibilities to commit a terrorist action. More than twenty experts were the respondents. The another parts of the practical part are the descriptions of the scenarios of the terrorist action, suggestions to the protection of the persons in the shopping center and the crisis plan for the shopping center to the solution of the expectional event which is describe in this theses.

Bank stabilizotion of Letovice dam
Mika, Jiří ; Pelikán, Petr (referee) ; Pelikán,, Petr (referee) ; Šlezingr, Miloslav (advisor)
The master's thesis is focused on the statistical evaluation of the most frequent level in the tank for 10 years, determining the abrasion terminant, setting retreat shoreline and bank stabilization proposals in the area of interest Svitavice on the water reservoir Letovice. The thesis consists of an accompanying report and a technical report. The accompanying report contains basic technical and administrative data, hydrology ratio and others conditions in the area of interest. In addition, the accompanying report contains a description of production and activities in wide surroundings of the tank. The technical report contains statistical evaluation of the most frequent water surface in the tank for 10 years, hydro technical calculation to determine the prognosis of the bank line recession, visualization proposal of biotechnical measures. In conclusion, an estimate cost of the proposed biotechnical measures is calculated.

Assurance of Security for Persons in the Buildings Intended for Exhibitions
Pečánka, Jiří ; Mika, Otakar Jiří (referee) ; Valášek, Rudolf (advisor)
The aim of this Thesis is to study the measures for securing the persons in buildings with higher danger of fire. In particular in buildings included in Act No. 133/1985 Coll. §4 Par. 2h. To compare the existing condition of securing exhibition buildings in the selected EU countries and the Czech Republic from the perspective of legislation and measures adopted. In more detail, to analyze the status of measures for protection of persons within the fairgrounds of the Veletrhy Brno a.s company. To evaluate the state and level of such measures and to propose a Methodological list - tactical procedures of action during emergency events in exhibition buildings.

Possible Misuse of Hazardous Chemical Industrial Toxic Substances
Gregorová, Renáta ; Dana, Čípková (referee) ; Mika, Otakar Jiří (advisor)
Bachelor thesis, „Possible misuse of hazardous chemical industrial toxic substances“, deals in the first part with legislation, which dictates conditions for handling with hazardous toxic substances. In the next part work covers with terrorism and chemical substances abusement in context with terrorism. Security of selected buildings and transport is also solved. The main aim of this work is to make a list of hazardous toxic industrial chemicals which are made in the industry of Czech republic and therefore can be abused easily. At the end of the work is the set of effective limitation of the potential abuse of dangerous toxic industrial substances provided and the guide how to behave in case of terrostist attack in the subway is designed.

Protection of Citizens during Emergency Situations
Kouřil, Jan ; Doležel, Ludvík (referee) ; Mika, Otakar Jiří (advisor)
My bachelor thesis is dealing with the Protection of Citizens during Emergency Situations. I used domestic as well as foreign literature sources over the past ten years. Part of presented sources, were elaborated with help of the Moravian Library Brno according to theme and key words. My thesis provides fundamental phrases and basic information about protection of citizens and its using at present time and in history. My bachelor thesis is dealing with adequate balance between protection and constriction of citizens, in application of civil protections procedures and equipment. Bachelor thesis also contains a proposal of expansion of responsibilities for civil defence authorities and finally proposal of state-of-the-art information system capable to spread emergency warning and instruction.
