Wireless Routers and Infuence on Climatic Conditions
Martinka, David ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
This thesis deals with problematics of installing wireless routers into specific locations depending on their heating and ideal signal transmission. The thesis is divided into eight chapters. The beginning of the thesis is theoretical describes the introduction into the problematics, the second part is practical and covers the executed experiment. The theoretical part contains six chapters – heat, signal, wireless router and measured climatic conditions. The practical part describes the executed experiment by thermo-camera which was used to scan wireless routers in IoT Lab in Avast Software company. Based on this experiment, the ideal position for installing the wireless router is then established. The conclusion of the practical part includes an analysis of the results of the questionnaire survey, in which technically skilled people were asked to describe the height of installation of their wireless router or whether did they consider heat and signal propagation while installing their wireless routers.

Short Distance Thermal Camera For Overheat Detection
Radvanský, Martin
During the development or repairing of electronic devices, we often meet problems with overheated components on the printed circuit board. For identification of overheating components, we usually use a thermal camera. The main aim of this project is to develop an inexpensive thermal camera for hobby usage.

Use of thermal imaging to determine the effect of ecstasy on the overheating of human organism
Kováčová, Tereza ; Svěcená, Kateřina (advisor) ; Minařík, Jakub (referee)
Basis: Ecstasy is often seen as a non-addictive substance, which can cause dehydration and dangerous overheating of the human body. Despite the fact that these side effects are often described in literature, ecstasy remains one of the most popular illegal drugs used in the dance scene. Objective: The main aim of the research was to prove the effect of ecstasy (MDMA) on human thermoregulation and on the subsequent overheating of the organism. Meanwhile we demonstrate that thermal imaging can be used to measure statistically significant differences in temperature in respondents currently under the influence of ecstasy versus sober respondents. The secondary aim was to assess the effect of the amount of used ecstasy on the resulting temperature of the organism. Methodology: Thermal quantitative data were obtained as physical measurements by thermal imager. Next to that, additional information was collected in the form of a brief structured interview with respondents. The research cohort consisted of 14 respondents of the control group who had not used any addictive substance before the measurement and 25 respondents of the study group who were currently under the influence of ecstasy (MDMA). Body temperature was measured in the face area, while a methodologically appropriate area of the inner corner...

Limit žhavení pro vyhodnocení rychlosti pomocí CTA termoanemometru
Antoš, Pavel
Paper deals with the velocity measurement by means of the CTA. Hot-wire anemometry is based on the heat transfer from the hot wire to the fluid. Limit of overheating is dependent on the probe geometry. The use of generalized form of the Collis-Williams law for common probes at low overheats has been discussed in detail.

Economic boom and fall of Baltic countries in 21. century
Filip, Michal ; Munzi, Tomáš (advisor) ; Štěpánek, Pavel (referee)
The focus of my work is to analyze the economic trend and development of the so-called "Baltic Tigers", from the beginning of the 21st century up to the present time. Here belongs the states of Estonia, Latvia and Lithuania. I'd like to concentrate on their mutual economic boom in detail, due to which they became an example for other successful transit economics, and also I'd like to depict the main cause of their GDP slump in the last period, which is related to the inception of the financial crisis. I'll be describing the situation in Latvia in particular, their unfavorable economic condition and future outlook. My paper holds forth on certain issues, such as reasons of the overheated economy, emigration, GDP negative accrual, short-term debts participation, increasing unemployment and social disturbance. In the closing part I'll try to outline possible economic forecast and solution of the actual matters.
