The aim of the thesis is to describe EBG substrate and exminate his influence on some types of antennas and choose one of them for realization. In first part this thesis describes the paramaeters of antenna in generall, in the second part is dedicated to introduction with EBG substrate mainly on the surface with the high impedance (HIES). The third part deals with the simulations of microstrip patch antennas with EBG substrate and without EBG substrate. In the last parts was designed and optimized antenna using superstrate.

Title: Kinesiology analysis of the horizontal jump in bike trial Cíle práce: The aim of this thesis is to verify the use of non-specific strength-training funds for the development of horizontal jump in bike trial. Methods: Content analysis of documents Method interview with assistant work Mgr. Marek Jelinek Ph.D. Method interview with the technician when recording data Case Study riders The method of data collection using surface electromyography Data Analysis Data processing software MS Excel - evaluation of differences of values sized muscle action potential in the different types of exercise Synthesis - making inferences and discussions Results: The list of exercises for developing strength abilities of the lower limbs, which are part of non-specific resources and influence the development of the horizontal jump in cyklotrial. Ranking exercises, which are in accordance with the measured values for effective development of horizontal jump in bike trial. The exercises are sorted from highest values aktivity of all muscles: 1st Squat with free weights 2nd Jump from second place 3rd Deadlift 4th Plyometrie 5th High Jump 6th Legpress Key words: Cycling trails, biking, surface electromyography.

Title: Skicross start analysis Objectives: The aim of this diploma thesis is to describe and evaluate the activity of muscles of upper body during skicross start and afterwards compare sides to find out, how is that movement symmetric or asymmetric. Methods: The diploma thesis is empiric-theoretic about case study. We used method of analysis and a method of comparison. For analysing the muscles activity, we used method of electromyography. We used comparison when comparing the activity of muscles on right and left sides. Results: After analysis of result we can declare the skicross start analysis is sym-metrical movement. Keywords: skicross start analysis electromyography Powered by TCPDF (www.tcpdf.org)

Surface diffusion of group III and IV metals on Si(100) is studied. Three methods for obtaining diffusion barriers are presented and discrepancies in published results are discussed. Room temperature growth of Al on Si(100) is studied using STM, observing a monomodal scaled island size distribution function. A Kinetic Monte Carlo simulation model is employed to obtain bonding energies and diffusion barriers for Al/Si(100). The best agreement between the measured and simulated characteristics is found for strongly anisotropic diffusion with barriers 0.60 eV in the direction orthogonal to the Si dimer rows and 0.80 eV in the parallel direction. Modifications of the cooling system required for observing metal adatom diffusion on Si(100) using STM are described and the first low-temperature experiment is carried out.

This thesis deals with monitoring changes in surface finishing of spruce and larch wood in outdoors. Using outdoor weathering tests the properties of two kinds of paints were tested by - a thin glaze and oil paint, two shades from each. In this work, the influence of the composition of the paint on its durability and light fastness was examined. This issue is closely related to the resistance of coatings to weathering, including solar radiation (UVA and UVB), atmospheric oxygen, relative humidity, temperature, precipitation, biological attack, chemical impacts (air pollution, acid rain, etc.).

This thesis is focused on water resources which supply drinking water to the city Dobříš and the nearby village Stará Huť. The first part is focused on clarification of the issue of surface and ground water in particular. Furthermore, water management and climate change, with possible adaptation measures. The second part is devoted to detailed analysis of the area of interest. This mainly concerns the development of population, major employers and amenities. The goal of this thesis is to determine the maximum daily water needs for 2025 based on variables indicators with respect to the land use plan of Dobřiš city and the village Stará Huť. The result values are compared to current yields of all water resources. The final summary proposes the possible solution for emergencies in case of declining yields.

Abstract Name: Bc. Josef Malinský, DiS. Diploma thesis topic: Impact of atmospheric factors and the type of coating on their durability when used outdoors. Abstract: This thesis deals with an assessment of qualities and lacks of coatings of a particular coating system. Its result is a recommendation of the best of the evaluated coatings. The introduction shows an analysis of the historical development of coatings and an overview of coatings in general, as well as a list of the most commonly used coating systems for the protection of wood used outdoors. The thesis describes the ways of applying coatings and the methods of correct applying coatings focussed on wood protection and durability. The aim of the second part is to choose the best coating according to the results and parameters of the testing. This part includes a description of the preparation of tested objects, applying coatings and the way of measuring the parameters before and after the exposure of such objects to an accelerated ageing process in accordance with the Czech norm ČSN EN 927 part 6. Comparing the qualities of particular coatings results in a recommendation of the best of the coatings assessed. The third part of the thesis describes a variability of atmospheric conditions and their impact on the results of the testing of coating systems. It results in an evaluation and assessment of particular differences in testing the particular coatings in accordance with the Czech norms ČSN EN 927 part 3 and ČSN EN 927 part 6. The aim of this part of the thesis is to answer the question whether and to what extent degradation of the tested coating is affected by the difference of climate conditions when being tested for accelerated ageing and natural ageing. Key words: surface treatment, wood coatings, testing, outdoor exposure
