Characteristics of the atmosphere of Mars for optical communication
Marčák, Tomáš ; Barcík, Peter (referee) ; Hudcová, Lucie (advisor)
The bachelor thesis is focused on the issue and research of atmosphere of the planet Mars for optical communication. The main goal of this thesis was to introduce the transmission through the atmosphere of the Mars and define possible wavelengths which could be used as possible communication. This thesis mainly introduces the optical communication and facts about the atmosphere of the planet. The main chapter presents more detailed analysis of composition of the atmosphere, the impact of the composition that is used for the radiation transmission. Lastly there are presented the results of the calculations and characteristics of the transmission through the Mars atmosphere. The next chapter is focused on theory of optical transmitters and its division. Subsequently, thesis describes the program for calculation of temporal, spatial and energetic characteristics of optical beam.

Meteorology and measurement techniques
Vaňousová, Jana ; Hammer, Jaromír (referee) ; Jebáček, Ivo (advisor)
This thesis deals with the branch of science called Meteorology. It is connected with measurement techniques, too. Basic terms are defined, structure and classification of atmosphere there are briefly described and furthermore basic meteorologic components are analysed. Finally there is an evaluation of meteorologic data measured unprofessional meteorologic station.

High precision differential thermometer
Sieklik, Ivan ; Wilfert, Otakar (referee) ; Barcík, Peter (advisor)
This work describes the principles of measurements of refractive-index structural parameter. This parameter represent intensity of atmospheric turbulence which is measured by a differential temperature meter. Basic properties of atmospheric transmission environment are specified and their influence on optical wave is stated. Furthermore, this thesis also describes fundamental types of sensors dedicated to temperature measurements. The aim of this work was to create a differential temperature meter which is able to measure the refractive-index structural parameter.

Ionic fields of various kinds and method of measurement.
Gubani, Ondřej ; Vaněk, Jiří (referee) ; Vognar, Jiří (advisor)
In the air there are positively and negatively charged ions with different mobility and size. The therapeutic effect of negative ions with high mobility is known. High concentration of negative ions occurs in speleotherapic caves. This bachelor thesis introduces the methods of measuring the concentration and mobility of various kinds of ions and their evaluation by spectral characteristics. It verifies the current mirror effect on the ions´ concentration in space. It also examines the effect of different types of ions in living organisms and an appropriate area treatment for the occurrence of negative ions.

Time lapse travel
Sodomková, Natálie ; Smetana, Matěj (referee) ; Vaněk, Vojtěch (advisor)
Project "Time lapse travel" is simple 2D adventure game, placed in real environment of Vodarensky les near Svitavy. Content is about fairy tales, folklore, time, magic realism and my own personal mythology. My goal is to create a specific atmosphere with stylization of the theme and distinctive visual art style. Whole project is a connection of experiments and digital games together to ask the question if its posssible for the interaction to provide a subjective atmosphere.

Program for the free space optical link power budged calculation
Vaculík, Jakub ; Hudcová, Lucie (referee) ; Křivák, Petr (advisor)
With increasing demands for transit capacity of data networks as well as communication network optical networks seem to be the suitable solution. Light beam is attractive to use for data transmission . Transmitted data can be expressed by means of light impuls.. For execution of the project we need the whole optical telecommunical system which consists of transmitter, transmission link and receiver. The target of transmission link is to transfer optical beam from its resourse to detector with minimal losses. The optical fibre or optical freespace optical link FSO are used for this purpose. Connection to internet by optical fibre is out of reach for most households and plants, it is very expensive and so far it isn´t in the offer of network operators and service providers. (at lest in our condition). But there is still the posibility to obviate optical fibre networks and reach high permeability and safety of communication by means of freespace optical links. It is much easier to implement, but only for short distance. FSO enables quick and even ecological communication which is in the world of more famous radio frequency networks very pleasant message.

Reentry CubeSat
Kopecký, Matěj ; Daněk, Vladimír (referee) ; Zikmund, Pavel (advisor)
This bachelor´s thesis deals with the analysis of the re-entry of the miniature CubeSat satellite from lower orbit. In the opening section, it is explained how re-entry process works, what bodies are typically used and the possibilities for protecting them from atmospheric resistance. The thesis is also focused on the mentioned group of CubeSat satellites and defines them according to general requirements. Using the knowledge learned from the opening section, a theoretical introduction to the preliminary analysis of the re-entry of the CubeSat satellite was put together, followed by a sample calculation. Here, it is explained how the CubeSat moves as it descends throughout the atmosphere and what parameters it needs to meet in order to make the re-entry.

Meteo Probe for the Measurement of Basic Atmospheric Quantities
Pumr, Martin ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
The bachelor thesis focuses on the problematics on basic atmosphere sounding. Its content is a study of the physical properties of the atmosphere. Based on these findings, the design and implementation of a specimen meteorological probe and ground receiving station are carried out. The meteorological probe records atmospheric data at regular intervals and stores them in CSV format. The probe continuously reports information about its position, and after completion of the measurement sends all measured data to the ground receiving station, where data evaluation and further processing takes place.
