Surface treatment for resistance improve of board materials with cement matrix and an organic filler
Zrza, Ondřej ; Vacula, Miroslav (referee) ; Bydžovský, Jiří (advisor)
As all materials used for exterior construction, cement-bonded particleboards also subject to climatic effects, such as frost, chemicals (eg. sulphates) or UV rays. Degradation of theese effects is slightly increased by organic base. Increased susceptibility can be eliminated by a effective coating, which reduces direct contact with aggresive influences on the board and provides longer durability. Theoratical part of this thesis analyzes different types of negatice influences and their effect on durability. Practical part contains selection of specific types of coating and assessment of their mechanical and aesthetic properties including spectrophotometric analysis of color change for each degradation effect.

Measurement of transfer speeds and delays in computer networks
Bárdossy, Adrián ; Kubánková, Anna (referee) ; Jeřábek, Jan (advisor)
Bachelor thesis is interested in measurement of transfer rate and latency in computer networks. In the first part of thesis is defined, which motodics of measurement we know, various RFC and their specifications, also various parameters about measurement in computer networks like bit rate, capacity of channel, latency. In the second part are prepared users interfaces and softwares for applying the measurement of thesd parameters. In the last part is application of these softwares and creating and testing methodic of network measurement.

Process Calibrator M143 - Climatic Testing
Dojava, Václav ; Bartoň, Jan (referee) ; Havlíková, Marie (advisor)
Subject of the bachelor thesis are the climatic testing of the M143 calibrator. Theoretical section of the thesis is concerned with the analysis and description of the norms used during climatic tests of electronic devices. Thesis then continues by describing properties and functions of the M143 calibrator and the Caliber programme, which is performing automated measurement during the climatic tests, on the basis of the designed calibration procedure. Practical section of the thesis describes the designed testing points and climatic conditions, which are adjusted during the testing. In this section the testing points are implemented to the Caliber programme. Last section contains the analysis and evaluation of the measured data gained during the climatic testing. From these measured data, we are to determine, whether the M143 calibrator is within the specifications stated by the manufacturer in different climatic conditions.

Evaluation of standard uncertainty of Climatic Chamber
Dojava, Václav ; Havránek, Zdeněk (referee) ; Šedivá, Soňa (advisor)
The thesis deals with the problematics of confirmation of the climatic chamber CTS 65/50, which is a component of CVVOZE testing laboratory. Theoretical part deals with the analysis and description of methods of confirmation of climatic chambers based primarily on technical standards. This part then contains a brief description of a theory of measurement uncertainty. Practical part deals with the design of measurement procedure, which was used for confirmation measurement of ten temperature setpoints. This section then also contains an analysis of the measured data with the evaluation of standard combined uncertainty of temperature measurement. The last part contains an evaluation of the confirmation results, which were the basis for the determination of whether the climatic chamber meets the requirements for the steady-state temperature stability inside the workspace resulting from the standards for the climatic testing

Systémy měření rozměrů a tolerancí v technické praxi
Hlaváček, Martin
The presented bachelor thesis researches the area of length measurement in engineering practice. It describes the possibilities of measuring length dimensions in practice using modern measuring systems. First, basic concepts in engineering metrology, measuring procedures and an introduction to basic length measuring instruments are defined. This is followed by an introduction to more advanced, more accurate measurement systems, namely measurement using pneumatic, electronic and optoelectronic gauges. The work mainly focuses on measurement using coordinate measuring machines in engineering practice. It also deals with the measurement of surface profile, especially the mean arithmetic roughness Ra. The thesis concludes with a discussion of modern measuring methods and outlines the shift in the use of coordinate measuring machines in engineering practice and anticipated future developments.

The Function of Speech in Husserl and Merleau-Ponty
Puc, Jan ; Novotný, Karel (advisor) ; Čapek, Jakub (referee) ; Janoušek, Hynek (referee)
The Function of Speech in Husserl and Merleau-Ponty The submitted doctoral thesis is an attempt to describe the development of the intentional function of speech in Husserl and Merleau-Ponty. The intentional function is defined as the change of expressed meaning that is engendered by the expression itself. We trace Husserl's position from the Logical Investigations and the first book of his Ideas pertaining to a pure phenomenology and to a phenomenological philosophy, where he describes speech as the non- productive mirroring of other kinds of intentionality, to the late text The Origin of Geometry, where he discerns two functions of speech: it provides thought its ideality, which is different from the ideality of species; and it provides thought its objectivity, i.e. the form of object that lasts in history as identical. In The Phenomenology of Perception, Merleau-Ponty adopts Husserl's late position with several profound modifications. The starting-point ceases to be the linguistic sign, and speech becomes a kind of gesture. As a consequence, the difference between linguistic and non-linguistic ideality disappears. Furthermore, Merleau-Ponty holds that the expression accomplishes the meaning of what it expresses. In this way, speech becomes creative and ceases to be just an empty intention of...

Development of tennis technique
Velebil, Matěj ; Kočíb, Tomáš (advisor) ; Carboch, Jan (referee)
Title: Development of tennis technique Objectives: The main object of this thesis is to analyse the fundamental factors that affect the development of tennis technique. Furthermore, this thesis presents the most common deviations from the optimal tennis technique, including their possible causes, and consequently suggests possible corrections that would help optimise the technique. Methods: Based on the analysis of documents, are present the fundamental factors that influence tennis technique. Specific selected deviations are develop from the optimal tennis technique on the parts of the basic strokes, in which the specific deviations, its description and the causes are stated. Furthermore, methods of correction to eliminate the mentioned technical deviations are proposed. This methods are based on the analysis of documents and observations from our own past experience. Results: The result is a detailed analysis of factors that affect the development of tennis technique. Furthermore, a list of deviations from the optimal technique with possible causes and proposed methods of their possible correction. The theoretical basis of the work deals with tennis technique as a fundamental factor influencing sports performance in tennis. Keywords: Biomechanics, exercises, correction, deviation, stroke

Dot product in school mathematics
Krejčí, Veronika ; Halas, Zdeněk (advisor) ; Škorpilová, Martina (referee)
Title: Dot product in school mathematics Author: Veronika Krejčí Department: Department of Mathematics Education Supervisor: Mgr. Halas Zdeněk, DiS., Ph.D., Department of Mathematics Edu- cation Abstract: The theme of the bachelor thesis is the dot product in school mathe- matics. The bachelor thesis is adressed to the teachers, who teach at the secondary school. The first part consist of an analysis of the textbooks, the result of the ana- lysis is the reason to write this bachelor thesis and to build a new introduction to the theme of the dot product. In the second part we build the new introduction. The third and the fourth part consist of application of the dot product. Keywords: dot product, hyperplane, distance, angle 1
