Time minimization for vehicles passing a given trajectory
Suja, Jerguš ; Kůdela, Jakub (referee) ; Porteš, Petr (advisor)
This bachelor’s thesis deals with model building of automobile movement and it’s optimal speed in every single point of trajectory, whit aim on minimal lap time. It uses a real data, which was measured on Masaryk circuit in Brno. Contents of thesis are analysing effecting forces on vehicle’s dynamic and then building mathematic model. The main purpose is finding optimal speed characterization and compare with real data. Then, we modify model with adjustable wing and present advantage of this customization. Simulation was done by program MATLAB.

Methods of analysis of vibration signals
Sivera, David ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The aim of the thesis is to focus on the different methods of analysis of vibration signals. Focusing on the physical fundamentals of vibrations and a description of their origin in an electrical machine. Describe the vibration sources from mechanical across the electromagnetic to the aerodynamic. Defining the current defects of electric machines and sensors suitable for the measurement of vibrations in an electric machines. Introduction to the methods of analysis of vibration signals in the time and frequency domain. Then using some of these methods for the analysis of vibration signals measured asynchronous motors with different manufacturer defined production defect. The conclusion is composed from the comparison between measured and analyzed results.

The Correlation between the Speed of the Source Speech and Simultaneous Interpreter's Performance.
Moravcová, Dagmar ; Čeňková, Ivana (advisor) ; Sládková, Miroslava (referee)
The purpose of the present thesis is to look into the correlation between the speed of the source speech and simultaneous interpreter's performance between Czech and French from the perspective of the French listeners of the source speeches in French, of two groups of interpreters (students and professionals) and of the listeners of the speeches interpreted into Czech. The thesis consists of the theoretical and the empirical part. The theoretical part outlines Daniel Gile's Effort Model and than focuses on the delivery rate of the source speech and on various theoretical approaches of different scholars, on the errors occured in the process of simultaneous interpreting, on intrepretation strategies and on the quality of interpretation. The empirical part describes the research method, the experiment itself and the results of the experiment which focuses both on the number of occurences of different interpretation stategies in relation to the source speech delivery rate and on the number of occurences of various error categories depending on the speed of the quasi-authentic source speeches. The empirical part examines the differences between the performance of the students and of the interpreters. Their performance is then assessed by the Czech listeners. Keywords simultaneous interpretation,...

Stimulation of strength, speed, and coordination, abilities in the ice hockey goaltender
Dohnal, Vladimír ; Perič, Tomáš (advisor) ; Vojta, Zdeněk (referee)
Thesis title: Stimulation of strength, speed and coordination abilities in the ice hockey goaltender. Aim of the thesis: To describe theoretical basis of stimulation in ice hockey goaltenders. To design a model of goaltender's strength, speed and coordination training and to find suitable methods, means and forms of the stimulation of strength, speed and coordination abilities focused on youth teams and older goaltenders. Method: Qualitative analysis of document contents was used to identify the main theoretical basis of stimulation of goaltenders strength, speed and coordination abilities. Determiners of goaltenders' strength, speed and coordination development were described on the basis of deeper analysis. The main theoretical resources were finally integrated into a logical complex by the method of synthesis. On this basis the conception of strength, speed and coordination abilities stimulation could have been set up and suitable methods, means and forms of the goaltenders' strength, speed and coordination training could have been chosen with focus on youth teams and older goaltenders. Results: The thesis discusses the topic of stimulation of goaltender's strength, speed and coordination abilities, describes the basic theoretical basis and determiners of goaltenders' strength, speed and...

Historic-geograpfical accessibility of Prague by road transport in 1918-2020 using GIS
Kufner, Jan ; Hudeček, Tomáš (advisor) ; Štych, Přemysl (referee)
The work deals with the centenarian development time accessibility of Prague using the road transport in the Czech Republic. Home research part is dedicated to the beginning of development of roads in the Czech Republic up to the planned completion of motorway network and also the matter of network analysis. The work seeks to demonstrate shortening the time distance from each places of the Czech Republic during the century. Parts of the work are isochronal maps of the accessibility of Prague and maps of changes in accessibility for single periods.

Drive Vertical Saddle of Machining Centre by Linear Motor
Zapletal, Radek ; Andrýsek, Radim (referee) ; Foller, Bronislav (advisor)
The diploma dissertation deals with the mechanism of vertical movement of a saddle of high-speed machining centre which is made by the Trimill company. The movement of vertical alloy saddle is solved by ball screw. The solution could be improved by replacing the ball screw by linear motor. This will dramatically improve the dynamics of the movement of the vertical saddle. In addition, if the weight is compensated by pneumatic relief and the construction is welded, the dynamics will further improve.

Speed Increasing of the Střelice - Moravský Krumlov Section
Dvořák, Jiří ; Šiške, Vladimír (referee) ; Hruzíková, Miroslava (advisor)
The aim of this thesis is to examine the possibilities of increase of speed on a railway track section between Střelice and Moravský Krumlov. The increase of speed is examined according to contemporary geometric parameters of the railway track. Sporadically an assessment with proposed changes of geometric parameters of the railway track is conducted. The proposed changes cannot cause any profound transformations of the body of the railway track. In both cases a restriction of speed by level crossing, a track branching and position of semaphores are taken into consideration. A proposal is elaborated with help of an overview of railway top.

The Students themselves - Student Center Poříčí
Veselá, Marie ; Látalová, Lucie (referee) ; Havliš, Karel (advisor)
The students themselves - Student Center Poříčí Waterfront with views of the city center, the hotel representative in the neighborhood and the traffic load over the streets of Vídeňská. Two opposites, which are daily faced a common corner. While I listened to the dialogue and decided to try to accommodate both "parties". The proposed building is therefore towards the river "looks" and along the streets of Vienna "running out". Horizontally curved strip of floor follow the flow of ambient life - throughout the building causing a glass surface feeling slowdown or stoppage, then head of the belts diverge and height glazing is reduced to the standard, so the speed increases and becomes a facade passerby more inaccessible. Containers with shaping gain more privacy and a wider cut views of the surrounding area. Broken facade indicates heart rate, not only outside but also the interior, where the dominant feature of the central corridor and provides insights into the other floors, the play of light and effectively slows down and speeds up the movement in the building. The unifying element is the central staircase cascaded current on all floors.
