Majorová, Michaela ; Vostrovská, Zdenka (advisor) ; Barák, Vladimír (referee)
The topic of this thesis are disabled people. The main goal of this thesis is describe the situation th these people in the labor market of Prague. This description is based on the founded data and the specialized literature. There will be explained the concepts of labour market, unemployment, aktive employment policy first in the theoretical part. There are for the next time explained the concepts of disabled people, thein characteristics, different type of these disabilities, legislativ of the employnment of these people, rehabilitation programmes and the enterprises with more 50 % share of employed disabled people. The practical part is based on the analysis of the selected dates of Český statistický úřad and Ministerstvo práce a sociálních věcí. There is included my own anonymus questionnaire research of selected eemployers. The goal of this research is to show, how is the situation of the employers and the diabled people in Prague. It was found by using this research, that the situation in our main city is very positive. Employers offer many employments to disabled people, althoug they don't have to do that and they don't have any statutory obligation.

Application of a measuring probes in turning process
Verfl, Jan ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
My diploma work is focused on implementation of measuring probe to process of cutting operation by turning and description of their effective usage ways. Measuring probe are used as correction during turning process or to control measuring of turning work eventually to signal mistake in process. In practical part the laser measuring probe is used to control shaft functional dimensions. Measuring is done after tooling and it substitute exit control. Laser probe was also reviewed regarding usability for given purpose as measurement tool and in the same time were reviewed time and cost differences against alternative turning process.

Design of airframe mold for ultra-light aircraft manufacturing
Zatočilová, Aneta ; Dočkal, Aleš (referee) ; Paloušek, David (advisor)
This diploma thesis deals with digital data processing during the design of a mould of ultralight airplane airframe. The final digital model meets the demands on manufacturability by using CNC machining. The realization, in compliance with the reverse engineering approach, was conceived in four phases, which had to be solved step by step in order to preserve the continuity of the process. The phases correspond to the main chapters of the practical part of the thesis. The first part is focused on 3D digitalization of airplane fuselage by using an optic scanner ATOS and photogrammetric system Tritop. The result of this part is digital data of fuselage geometry in form of polygon grid. Next part deals with software reconstruction of collected data – by optimizing polygon grid in order to provide suitable base for surface modeling. The third part, the most time demanding, handles the creation of airplane fuselage surface model. Geometry has to satisfy requirements for smoothness and tangential or curvative connection of surfaces, including other requirements resulting from model usage. The final part of the thesis documents the procedure of deriving a mould from the aircraft fuselage geometry.

Integration of Children and Youth with Mental Disabilities within the framework of Free-time Activities with a special view to the Scouting Movement
Jeníkovská, Lenka ; Šiška, Jan (advisor) ; Strnadová, Iva (referee)
Thema of this thesis is integration of childrens with mental handicap into their leisure time. Especially it is focused to their integration into the scout group. The goal is to show one of the possibilities how childrens with mental handicap can spent their leisure time in the environment of intact peers. In theoretical section is definition of terms like integration and leisure time, their basic description and approach. In following section is short summary of question about mental retardation. It is focused on Down syndrom and autism. These questions are related to cases in practical section. Empirie section is presenting results of survey which was applied to scout leaders. This survey is about approach to integration, their experiences and practical options. Thesis continue with case study of two scout departments where were implemented two childrens with mental handicap. Information, especially from practical section, should help to improve possibilities of integration childrens with handicap into their leisure time.

Physical Load Analysis In Woman's Beach Volleyball
Maciolková, Hana ; Vorálek, Rostislav (advisor) ; Buchtel, Jaroslav (referee)
Title: Physical Load Analysis In Woman's Beach Volleyball Objectives: The objective is to examine time characteristics, cardiac strain, movement pattern and the individua! volleyball skills in woman playing beach volleyball. The results will help aid athletes and coaches to improve individua} and team performance in the sport. Methods: Analyses of the thirteen game records were used to compile data for statistical time measurements, movement pattems and individua! volleyball skill. Through the use of sport testers, four individua} athletes in four separate toumaments had their heart rates recorded. These heart rates were further analyzed to collect the appropriate data for cardiac strain characteristics. Results: The average game time was 37 minutes with 5 - 9 seconds exercise loads and 15 seconds recovery time. Beach volleyball is high to middle level intensity game with mixed aerobic- anaerobic energy supply system in use. The average heart rate falls in the interval of 150 and 180. The jumping load is about 41 and more jumps counting serve jump, block and spike. The prevalent movement distance is within 4 meter range. The results also shows that the blocking player is under large physical stress while changing repeteadly position between defence on the net and in the field. Keywords: Beach...

The try of reconstruction sacral topography with special attention of church st. James the Greater in Jihlava in Middle Ages
Vodáková, Dana ; Kuthan, Jiří (advisor) ; Scholz, Stefan (referee)
RESUME The concern of this thesis is one of the sacred building of Jihlava town, the parish church of St. Jacob the Bigger. The main object of interest is the oldest history of this temple, which extends to the time of forming of its own city. It attempts to summarize the known knowledge and also to consider the new findings, mostly the character of archaeology. Therein, it is needed to mention, that most of the founded situations were not appropriately to the moment of usage accessed, concerning the state of actual examination, which is limited by building reconstructions. Generally, it is possible to state, that the actual results seem to be aligned with the historical development of the temple. The attention was dedicated also to church building, which is thought to be built before the today's temple, we consider this from different angles of point of views. The one of them was the intention to examinate the possibility of destruction by the fire, which is indicated in pope list as well as the susceptibility measures of construction parts originated from this building, later on used on the actual church building. In dependence on the older construction and archaeological point of views the possibility of pre-allocated habitation on the place of current town was newly revised in the work. The part of the...

Vodní a hybridní plazmatrony s plynovou a vodní stabilizací
Hrabovský, Milan
Plasma torches with water-stabilized arc (Gerdien arc) are utilized in plasma processing for specific applications. In water-stabilized torches an oxygen-hydrogen plasma jet is produced. The torches are characterized by very low mass flow rates and high power. Plasma enthalpy is thus several times higher than enthalpy of plasmas generated in gas-stabilized torches. High enthalpy is accompanied by very low plasma density. Also other plasma parameters substantially differ from the ones in gas torches. New type of plasma torch with combined stabilization of an electric arc by water vortex and gas flow was investigated. This hybrid water/gas stabilization offers possibility of adjustment of plasma jet parameters in a wide range from high enthalpy, low density plasmas typical for liquid stabilized torches to lower enthalpy, higher density plasmas generated in gas stabilized torches.
