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.

Wind shear as a dangerous fenomenon in aviation
Novozámský, Adam ; Jebáček, Ivo (referee) ; Krška, Karel (advisor)
This thesis is about wind shear and its influence on aviation. There is wide theoretical description of wind shear and it’s implemented into aviation practice. There are also methods of observation, forecasting and reporting, for both pilots and meteorologist described. In this thesis, pilots can find useful recommendations for dealing with wind shear during the flight. Every reader can also read about famous aviation accidents and look at models of weather that caused those accidents. At the end of thesis there are analyses of a rawiosonde measurements related to wind shear reports. This whole thesis is focused on increasing awareness of wind shear in aviation from angle of view of both pilots and aviation meteorologist.

Effect of volcanic ash to Air Transport
Soukop, Robin ; Šplíchal, Miroslav (referee) ; Chlebek, Jiří (advisor)
This master's thesis deals with the issue of volcanic ash as a complex and its impact on aviation, including the volcanic activity itself (conditions for its existence, for existence of eruptions and their basic products). In addition, the thesis also deals with effect of volcanic ash on aircraft and airports, possibilities of its detection or monitoring as well as mechanism of its spreading in airspace. The emphasis is laid mainly on air incidents related to volcanic ash and on danger it poses to the airspace of the Czech Republic.

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.

Ion fields measurement
Svozil, Radek ; Szabó, Zoltán (referee) ; Steinbauer, Miloslav (advisor)
The aim of this semester project is the introduction to the problematic of ion fields, where and under what circumstances they originate and extinct and the techniques of measurement. The project will deal with the atmosphere and the electrical field of the Earth. I will consider the composition of the atmosphere and the principles of origin and extinction of ions. I am going to mention the division of ions and their influence on the living organisms. Another topic to be dealt with is the methods for measuring the air ions and the small currents. Gradually we are going to learn the known methods of the measuring of air ions. We are going to get a closer look at the method of measuring with the cylindrical aspiration capacitor. We are also going to deal with the problem of measuring very low currents, where they originate and how it is possible to compensate them. The outcome of the project should be the concept and later the creation of the sonde for the measuring of the ion fields itself.

Spectral properties of daylight as time-spatial function
Mayer, Jan ; Drápela, Jiří (referee) ; Baxant, Petr (advisor)
Graduation thesis describes basic data about Sun, suns constant, solar radiation thoroughfare by the earth's atmosphere. Thesis describes effects of components of optical radiation and physical character of solar radiation. Thesis also describes character of day lighting in nature, spectral distribution of natural lighting, average time of sunshine. The next point of thesis is description of measuring equipment Konica Minolta. In chapter measuring procedure is described measuring process of the sky radiance. Measurement analysis is mentioned in conclusion.

Thermal baths Yverdon, five senses in architecture
Lišková, Nela ; Uřídilová, Marcela (referee) ; Koleček, Ivan (advisor)
The spa area is located in western Switzerland in Yverdon-les-Bains, which extends along the southern shores of Lake Neuchâtel. The aim was to replace the current Spa complex which capacity and operationally not meet today's requirements and also to increase capacity accommodation in the form of hotel. New spa complex is placed as solitaire in the area between the spa parks which creates fluent transition between them. Spa function is divided into multiple objects that have their own character, but which in their complexity creates one house. These objects "float" on the surface of the water, unites them and divides its operations at the same time.

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.

Horror Atmosphere in E. A. Poe's stories
KAŠPAROVÁ, Tereza
The goal of this bachelor thesis is to describe the means Edgar Allan Poe uses to create the atmosphere of horror in his short stories. The first part of the thesis deals with themes as the most obvious of the means that Poe employs. The themes analyzed in this chapter recur frequently in the stories and have the most powerful impact on the reader. The second part of the thesis focuses on the setting and in the third and final part the narrative style is discussed.
