Analysis of the meteorological dates
Králík, Martin ; Čmiel, Vratislav (referee) ; Rozman, Jiří (advisor)
The aim of the bachelor’s thesis is to recognize the basics of atmospherical physics, the techniques and measuring instruments used in weather stations and the statistical analysis of three chosen meteorological parameters. Data analysis is made by using graphical display method, which is discussed later on.

Miniaturized Measurement System for Wind Speed Estimation.
Štěpánek, Michal ; Vágner, Petr (referee) ; Urbanec, Tomáš (advisor)
This thesis is analysis of thermal anemometer, which contains design and realization. For measuring wind speed there are not used any mechanical moving parts in this way. This measuring uses two thermistors. One of these measures temperature of air, which is very important for compensation of whole system. Temperature of second thermistor is kept on constant value. This value is higher than surrounding air temperature about constant difference. Fluctuant air cools this sensor and because of that systém must supply more of heat. By analysis of value of supplied heat, we can calculate the wind speed value.

Analysis of the meteorological dates
Votavová, Barbora ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
The aim of this study is to recognize structure of data from the meteorological station, choose useful programme for its analysis and make a theoretical analysis and graphics. The work describes the collection of data from meteorological stations, data stucture, meteorological elements, their measurement and selection of appropriate statistical program. Practical part includes charts with commentary. Conclusion summarizes the results of the analysis.

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.

Effects of sudden air temperature and pressure changes on mortality
Plavcová, Eva
It has been shown that weather influences human health; however, little attention has been payed to the role of sudden changes of weather characteristics. In this work we developed an algorithm for identification of sudden changes of air pressure and temperature over the Czech Republic. Events were selected from the data covering 1986-2005 and were compared with the database of daily all-cause (total) mortality and mortality due to cardiovascular diseases, both for the whole population and for people aged 70 years or more. Increase of mortality was found after significant temperature increase or pressure drop both in summer and winter months. Decrease of mortality occured after significant pressure increase or temperature drop in summer. Mortality variations are usually more pronounced for population aged 70 years or more, and sudden temperature changes affect mortality on cardiovascular diseases more strongly. Changes in mortality were found after passages of cold fronts in summer, too.
