Cell - Phone Effects on Human Health
Pieniažek, Ireneusz ; Křepelka, Václav (referee) ; Filka, Miloslav (advisor)
This bachelor’s thesis is dealing with the influence of cell phones on man. First part is focused on the introduction to the problems of cell phone communication. There are described the frequencies and wave lengths, which the cell phones use. Here is also described the principle of cell phones functioning. Second part is devoted to influence of the cell phones on the human body. It is discussing the electromagnetic compatibility of the biological systems and describing the electromagnetic field occurring in cell phone communications. There are also described the thermal effects of the cell phones and this chapter further discusses the hypothesis about the non-thermal effects of the cell phones. There is a description of mechanism of influence of radio waves. This part also describes the possible health hazards resulting from the use of cell phones and the problem of relationship between the occurrence of cancer and the use of cell phones. There are mentioned other ecological problems connected with cell telephony. Third part is focused on the SAR measurement (specific absorption rate) of the cell phone. Here we can find the definition of SAR. It describes the tested apparatuses, the procedure of measurement and measured values for GSM 900, GSM 1800 and W-CDMA 2000 standards. Tested apparatus in this case is Samsung SGH-Z140V. We can find here technical engineering solutions, which are aimed to minimize the specific absorbing power absorbed by human body during the use of apparatus.

I Live Tarot
Oplatková, Hana ; Vondřejcová, Silvie (referee) ; Klímová, Barbora (advisor)
Private deck of cards created during six-month survey and documentation of daily experiences. The package contains 49 cards and it is inspired by a set of 78 tarot cards. Text content - reverse side of the card was created using diary notes. Face side of the card was chosen as a representation of processes taking place usually in days when the card was read.

Study of the influence of process parameters on welding properties of ferritic stainless steel in laser oscillation welding
Křepela, Petr ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
The aim of this work was to carry out an experiment to assess the influence of the individual welding parameters in the laser welding method with the beam wobbling on the made weld, respectively. welds. The material which was welded was ferritic stainless steel with the designation 1.4016, which, like all ferritic steels, is susceptible to coarse grains and the resulting brittleness which leads to degradation of the mechanical properties of the weld. The welds were compared to a sample welded without wobbling an between themselves. Unfortunately, however, the evaluation of the test samples did not bring significant differences from laser welding without wobbling, however some changes are evident, such as grain orientation, weld defects, or uniformity of mechanical properties over the weld length, where wobbling frequency is most important. Further research should focus on limiting the porosity at higher wobbling frequencies in the shape of a circle or ellipse.

The impact of territorial infrastructure development on the real estate market
Žižková, Kateřina ; Kocourková, Gabriela (referee) ; Krejza, Zdeněk (advisor)
The diploma thesis deals with how the influence of territorial infrastructure affects the real estate market in the border regions of the Czech republic, Poland and Germany. In the thesis are created databases about localities and realities, that are the outcomes of the data collection. Data collections mainly concerns the type of property, layout and the location of the property. From the data analysis is possible to evaluate the influence of territorial infrastructure in the context of average market values of real estates in the border region Czech Republic-Germany-Poland.

Evaluation of optical components for LED
Dobiáš, Jiří ; Pavelka, Tomáš (referee) ; Škoda, Jan (advisor)
This thesis deals with an evaluation of optical components for LED, which is based on laboratory measurements of available LED samples and optical elements. The evaluation is done according to established standards and is focused on efficiency and adjustment of luminous flux (beam angle, luminous curve). Furthermore was made a study engaged in an optical element influence on LED color properties (color temperature, spectral characteristics). In conclusion there is an optical elements usage overview and recommended procedure for selecting appropriate combination of LED and optical element.

Dispersed production and its influence on distribution network
Kácl, František ; Vybíralík, František (referee) ; Mastný, Petr (advisor)
The diploma thesis deals with dispersed generation (production). The small electric power sources are connected into distribution networks. Types and principles of the small electric power sources are studied. The legislation framework concerning renewable energy sources utilization is described. These power plants have impact into distribution networks and therefore techniques for the source connection to distribution network are included in the thesis. The impact of the specific small source of electricity must be studied.

Development of housing construction in the border region
Pazour, Tomáš ; Vaňková, Lucie (referee) ; Krejza, Zdeněk (advisor)
The diploma thesis deals with the analysis of a selected segment of the real estate market in a specific border locality (CZ-DE-PL). Furthermore, the influences and development that affects the real estate market with a focus on housing construction in the context of regional development. Based on the collected data about available properties and locations, databases are created where properties are divided by type, layout and size. From these databases, the average market prices of real estate are then calculated, that are then compared within the border regions. The prices reflect all the positive and negative properties of buildings and localities that may have an impact on the price of real estates in the surveyed localities. The last part compares the regional development of housing units in border regions.
