About identification of motor predispositions in triathlon
Kovářová, Lenka ; Bunc, Václav (advisor) ; Čepička, Ladislav (referee) ; Zháněl, Jiří (referee)
Title: About identification of motor predispositions in triathlon Aims: The aim of our study was to find and verify appropriate indicators predicting the on-coming performance in a short triathlon and determine their level for the junior category. Methods: In our study, we combined quantitative and qualitative approaches with a predominance of quantitative methods. In the first phase of the research, we used quantitative methods, confirmatory factor analysis for verification of models of predispositions and elaboration of performance standards for individual tests by means of T-points. In the second part of the research, we used the qualitative method (casuistic studies) to validate the test battery and its application in practice. Results: We have compiled a structural model of motor predispositions for short triathlon, which explained 91% of all cross-correlations of seventeen used indicators. Predispositions for triathlon were categorized into five separate groups; for swimming, cycling and running (i.e. according to individual disciplines), and functional and psychological predispositions. Finding a lower limit boundary of performance in the completed tests is considered to be the most important issue for the assessment of future performance in triathlon. As a lower limit we have set the zone...

Šulc, Miroslav ; Horáček, Jiří (advisor)
Title: Excitation of molecules by cold electrons Author: Miroslav Šulc Department / Institute: Institute of Theoretical Physics, Charles University in Prague Supervisor of the doctoral thesis: prof. RNDr. Jiří Horáček, DrSc., Institute of Theoretical Physics, Charles University Abstract: Several methods for low energy collisional processes are investigated. In the first part, attention is especially devoted to examination of applicability of the R-matrix method combined with the Schwinger-Lanczos (SL) variational principle for potential scattering with long-range forces. Next sections deal with the development of the interaction correlation-polarization (CP) potential in the framework of the Dis- crete Momentum Representation (DMR) method on the grounds of the Local Density Approximation in the Density Functional Theory (DFT) context. Obtained results are then utilized in body-frame (BF), static exchange + polarization (SEP), calcula- tions within an analysis of experimental data for e−-N2 scattering comprising a part of a larger project addressing theoretical examination of rotational excitations of small molecules in the gas phase induced by electron impact. For N2, a new phenomenon consisting in suppression of backward cross-section below 95 meV is observed and con- sequently attributed to...

Personal prose with an authorial commentary
Hereinová, Olga ; Peterka, Josef (advisor) ; Mocná, Dagmar (referee)
RESUME The thesis 'Personal prose with an authorial commentary' consists of two parts. The first part is the authorial prose. The prose is titled The Subject: This is a novel in emails describing a partnership triangle. Jirka responds to Danka's advertisement on an Internet dating site looking for a pen pal. Although both of them are living with a partner their pen friendship grows into a love afair. The relationship and intimacy of characters are revealed through the correspondence of other people. Not only does Jirka correspond with Karel, his friend, but also his girlfriend confides Jirka's behavior to her friend Šárka. Jirka gets himself into a difficult position between two women. They then resolve the situation for him - both abandon him. In the second part of the thesis - reflection - the circumstances of the work's origin are discussed and particular aspects of the novel are reflected. In addition to the plot construction, character configuration and their characteristics the main focus is on the meaning of the work, and due to which the work's conclusion and the title have suffered. Coping with the form of emails, which is used in the novel, is also taken into consideration and the inclusion of the text into the genre of women's literature. The inability to cross autobiographical borders and...

Title: Analysis of teaching geography in upper secondary educational level in Germany Author: Bc. Eliška Jindřichová Department:Department of social geography and regional development Supervisor: RNDr. Dana Řezníčková, Ph. D. This thesis contains an analysis of the conception of geographical education on ISCED level 3 in Germany. It aims to answer the following basic conceptual questions: Under which conditions is geography being taught? In what manner is geography being taught? What are the expected effects of geographical education on the pupils? During the discussion of conditions, the current status of geography as a teaching subject is presented and the possibilities for cross-curricular collaboration are pointed out. Emphasis is placed on the analysis of form and content, learning objectives/goals and creation of geographical skills. Another part of the thesis is the description of the process and methods used to evaluate the gained geographical knowledge of pupils. The basic method for obtaining relevant data is content analysis of the curricula of the federal states of Germany, resulting in a set of complete record sheets. Based on the chosen method of data collection and analysis, I got all the answers to the three basic conceptual questions and compare the resulting data to Czech...

Mahová, Eva ; Štych, Přemysl (advisor) ; Schneider, Michal (referee)
Spatial analysis of illegal migration in the Czech Republic 2005-2007 Abstract This thesis deals with the spatial analysis of illegal migration across so-called green border from the Czech Republic to Germany and Austria in 2005-2007. The main data set was acquired from Czech Alien Police Service and Ministry of the Interior of the Czech Republic and contains also spatial component. For all places of detention various indicators characterizing geomorphology, landscape structure or distances from the closest routes, settlements and border checkpoints are computed. We can identify main aspects related to the choice to illegally cross state borders by merging the database of anonymous personal data of persons detained while illegally crossing the border and geographical data describing the nature of the place of detention. Keywords: illegal migration, GIS, Python, spatial analysis, correlation, regression

Measurement of amplitude and phase of ultrashort optical pulses by using nonlinear processes in optical fibres
Vraný, Boleslav ; Kaňka, Jiří (advisor) ; Karásek, Miroslav (referee) ; Boháč, Leoš (referee)
I confirm that I worked out this doctoral thesis independently and that I quoted all the literature used. Prohlašuji, že jsem tuto dizertační práci vypracoval samostatně a že jsem uvedl veš- kerou použitou literaturu. V Praze dne 21. 6. 2010 Abstract The thesis deals with the Frequency-Resolved Optical Gating (FROG) method of mea- suring ultrashort optical pulses. As a nonlinear process involved in the method we used cross-phase modulation in a microstructured optical fiber. The FROG device made of fi- ber pigtailed components fitted well the needs of our fiber optical laboratory. The output of the measurement differs significantly from FROG methods that use other nonlinear processes like second harmonic generation. For our FROG, the standard algorithms for reconstruction of the complex envelope from measured spectrogram failed. We therefore used a more robust genetic algorithm (GA) for the reconstruction. GA has several pa- rameters that affect its runs and we explored the influence of these parameters on the success of reconstruction of a number of test pulses and found the optimal set of these parameters. In this work, we present a general discussion of the FROG method and the standard reconstruction algorithms, the experimental setup we used, a discussion of the genetic algorithm, the technical details of our...

The effects of extreme physical and mental stress on the human body
Braumová, Lucie ; Bartůňková, Staša (advisor) ; Majorová, Simona (referee)
Title: The effects of extreme physical and mental stress on the human body Goals: The main goal of this work was to evaluate the effect of physical stress load in a five-kilometer-long race in cross-country skiing on physical and mental functions of high school students. Methods: The investigated group consisted of 10 boys of the average age of 16 years. To evaluate their level of physical fitness and circulatory responses during cross-country stress, the maximal treadmill stress test was used. Circulatory response before, during, and after the race was monitored by a Sport-tester. To evaluate the mental background and the actual condition under the stress load, standardized questionnaires on ability to cross-country skiing, stress management strategy, degree of physical discomfort and current mental state were used. Results: The reference file tested by a stress test up to the maximum proved an above-average aerobic fitness. The extreme stress situation was a five-kilometer-long race in cross-country skiing. The results were processed and evaluated with a statistical and factual relevance. A number of correlations were made. The average SF values, which were achieved during the race, were getting near the maximum values (96% of SF max.). Even the evaluation by a Borg RPE scale attested to the...
