Vliv současných trendů na determinanty sportovního výkonu v triatlonu / The influence of the current trends on the determinants of sports performance in triathlon

Červenka, Lukáš January 2021 (has links)
Name: The influence of the current trends on the determinants of sports performance in triathlon. Aim: Main aim of the diploma thesis was to find out the influences of current trends in triathlon and how they can influence the determinants of a sports performance and predict in which direction the triathlon will go in the future. Methods: According the historical method by Hroch it was used to determine the historical context. The results were properly interpreted in the context of a problem definition, data collection and analysis based on inductive- deductive reasoning. The research deals with the search, processing, and analysis of data for various types of triathlons within the International Triathlon Union (ITU). The results from several selected triathlon races of the world championship are also analyzed, from the shortest format (super sprint) to the longest, which is a long triathlon (Ironman). The research also included an interview with an employee of the Commission of the International Triathlon Union (triathlon development committee) Outcome: According to the analysis of historical development, triathlon competitions are shortening, and the share of triathlons is rising at the expense of Olympic triathlons. There is no fundamental difference in BMI values between the best super sprint...

Korelace změny signálu AE s rozvojem kontaktního poškození / Correlation of AE Signal Changes to Rolling Contact Damage Propagation

Nohál, Libor January 2015 (has links)
This PhD thesis deals with the experimental study of more precise rolling contact fatigue damage detection using acoustic emission method. A series of experiments was carried out on two representatives bearing steels and the analysis of sensitivity for the presence of contact damage was performed on selected parameters of acoustic emission. The extent of damage was classified into four classes and signal parameters the most characterizing the development of damage were correlated with the extent of damage. It was also verified the influence of lubricants on acoustic emission signals. The results have an impact on the implementation of more precise rolling contact fatigue tests and evaluation of parameters of acoustic emission signal. On the basis of experiments was established methodology for more precise RCF testing method using acoustic emission on test-rig AXMAT II.

Adaptivní regulátory s prvky umělé inteligence / Adaptive Controllers with Elements of Artificial Intelligence

Šulová, Markéta January 2009 (has links)
The aim of the thesis is to improve the control quality of the adaptive systems (Self Tuning Controllers). The thesis mainly deals with problematical identification part of the adaptive system. This part demonstrates a weak point for existing adaptive systems. Paradoxically, the quality of the adaptive system depends mainly on the identification part because on the basis of the process model obtained by identification are worked out parameters of a control part, afterwards the control action plan is established. Knowledge of the modern control methods is used and a new identification algorithm for closed loop identification is proposed. This simple, fast and efficient algorithm overcomes all disadvantages of current classical identification methods based on least mean-square algorithms. The possibility of the choice of a short sample time, one tuning parameter ability to adjust the control process, the ability to identify processes in real use belong to its main goals. This algorithm was built in the adaptive system and then it was tested on a set of simulation and real models with surprisingly excellent results. The successful implementation of the algorithm into the programmable logic controller was also realized. One part of the thesis introduces a new universal graphics environment for testing and verifying control algorithms.

Identifikace a původ drahých kamenů v insignii Univerzity Karlovy v Praze, Přírodovědecké fakulty / The Identification and the Origin of the Gemstones Adorning the Insignia of the Charles University in Prague , the Faculty of Science

Petrová, Zdeňka January 2010 (has links)
The issue of a sceptre for the newly founded Faculty of Science was first discussed on the meeting of Faculty professors on the 25th November 1921, more than a year after the separation of the Faculty of Science from the Faculty of Arts. The commission elected from among the professors proposed a motion that the new Faculty sceptre should resemble the sceptre of the parental Faculty of Arts. Through a mediation of the Ministry of Education and National Enlightment the design of the new sceptre was ordered from the Academy of Arts, Architecture and Design and it was elaborated by prof. Jaroslav Horejc. However, in January 1923, his design was rejected, because it didn't meet the requirements of the professors' conservative approach. When prof. Horejc refused to make a modified copy of the sceptre of the Faculty of Arts, the professors addressed Tengler, the goldsmith who had made the sceptres of other faculties and of the rector in previous years. Alois Tengler was willing to make a modified copy of the sceptre of Faculty of Arts, but he also proposed a new design (with estimated price of 20 000 K), which the professors found more suitable and subsequently this design was adopted. Tengler committed himself to manufacture the sceptre by the 15th November 1924 and to incorporate any additional design...

Aktivní slovní zásoba vztahující se k vnímání těles u dětí ve věku 5 - 6 let / Active vocabulary connected with the perception of

Skalová, Dana January 2011 (has links)
The thesis deals with active vocabulary related to the perception of solid objects by 5-6- year-old children. The main objective of this thesis is to map which verbal expressions the children use when recognising, comparing and identifying solid objects, how they are able to cope with the deficit of the respective vocabulary, what details they notice most often in describing, identifying and comparing solid objects, or what is most easy for them and, by contrast, what they are not able to express in words. To meet this objective, an experiment method was applied. The experiment was conducted in two kindergartens according to the scenario prepared in advance, using a set of wooden solid objects, which the children were to identify, describe and compare. The contribution of the thesis consists in the fact that it addresses the topics related to pre- school age, which are not elaborated in more detail in the available literature.

Demonstrativní predeterminant v současné francouzštině a jeho fungování v textu / Demonstrative pre-determiner in current French and its functions in text

Bečvářová, Karolina January 2011 (has links)
demonstrative determiner - actualization - identification - reference - deixis - anaphora - cataphora - literary narative text Demonstrative determiner actualises and identifies a noun by designation the referent of this noun. Demonstrative determiner designates the referent in space (physical surroundings of the speaker), in context, or in common shared experience. In literary text, demonstrative determiner designates the referent in context by anaphora or cataphora, in some cases it designates the referent in fictional space.

Využití dlouhodobé formantové distribuce pro rozpoznatelnost mluvčího v různých akustických podmínkách / Using long-term formant distributions for speaker identification in various acoustic conditions

Lazárková, Dita January 2015 (has links)
The analysis of long-time formant distribution is relatively young but promising discipline of speaker identification. It is a method of mapping the long-term behavior of formants in speech of individual speakers. Frequently encountered problems in practice are bad acoustic quality and very short duration of analyzed recordings. This work aims to present the historical development of forensic phonetics and currently used methods. In the practical part, it deals with the usability of LTF method in forensic practice, especially in recordings containing background noise. It was shown that the noise appreciably affects extracted LTF values and unfortunately the change is not systematic. Therefore, we proposed several methods to compensate the noise in recordings, in order to be able to compare recordings with and without noise. We also investigated the minimum duration of recording, which is necessary for statistical reliability of the resulting values. This boundary is not exact and for each speaker, it is substantially individual. But it is apparent that recordings (vocalic streams) shorter than 15 s often provide incomplete information, wherefore they cannot be recommended for analysis. Keywords: LTF, long-time formant distribution, speaker identification, forensic phonetics, acoustic quality of...

Janeček, Miroslav January 2015 (has links)
Money laundering can be defined as a process of converting the proceeds of illegal activities to legitimate money or other assets, or as a process whose aim is to conceal the origin and ownership of proceeds that come from illegal activities. Its main phases are placement, layering and integration. The main sources of dirty money are drug trafficking, procuring, arms trafficking, extortion, robbery and property crimes. The aim of this thesis is the analysis of the fight against money laundering in terms of financial law and from institutional point of view, evaluation of its success and the formulation of my own opinions on the possible improvement of the system components. The first part of thesis deals with the term of money laundering, its phases and characteristics and history. The second part analyses the legislation at international, EU and national level. Attention is paid to the AML Directives and to the AML Act.
