Tram wheel modelling for dynamic analysis
Pešek, Luděk ; Veselý, Jan ; Podruh, J.
The wheels as vibration transformation elements and noise emitters substantially contribute to the tottal noise level of riding vehicle. Therefore rubber like material is also utilized for construction of the silent wheel. We aimed at investigation of dynamic behavior of raiway tram wheel with a special construction. The dynamic parameters of the wheel are studied. The numerical modelling, computation and analysis were performed in ANSYS Release 6 environment.

Motion in Faulkner: An Analysis of Movement in The Sound and the Fury
Hesová, Petra ; Ulmanová, Hana (advisor) ; Matthews, John Thomas (referee)
The Gothic is an extremely viable mode in the history of American literature. As a genre concerned principally with distortions and aberrations, it provides a platform for writers to voice their concerns about periods of transformation and destabilized boundaries. William Faulkner, one of the leading authors of the American South, frequently employs the Gothic mode in his portrayals of the South as a traumatized region trying to cope with the echoes of the Civil War and with the disintegration of old aristocratic values, which manifests itself in the decay of institutions (such as the family) as well as a collapse of individual minds. This emphasis on the human psyche is evident especially in the novel The Sound and the Fury, whose main characters and narrators are representatives of the various extremities of the human psyche (severe mental retardation, suicidal tendencies, schizophrenia and paranoia). Faulkner's use of the Gothic mode is rather unorthodox and innovative, employing inversions and parody which can be appropriately demonstrated by the category of motion and his use of the traditional Gothic devices and character types. The traditional motion patterns - flight and pursuit, quest and purposeless wandering - that are originally connected predominantly with only one Gothic type (the...

Střihové napětí na stěně pod velkou bublinou stoupající v nakloněném plochém kanále
Tihon, Jaroslav ; Pěnkavová, Věra ; Vejražka, Jiří
The motion of single air bubbles in an inclined flat water channel is investigated experimentally. The electrodiffusion technique of near-wall flow diagnostics is applied to measure the wall shear stress distribution under large bubbles rising along the upper channel wall. The electrodiffusion measurements are synchronized with the visual observation of bubble movement done by a high-speed camera. The analysis of video records provides information on the bubble shape and terminal velocity. The experiments are carried out for three different channel heights and cover a wide range of channel inclination angles (from horizontal to vertical position). The experimental results on bubble motion characteristics obtained in stagnant and upward-flowing liquid arrangements are confronted with the recent predictions and scaling provided by theoretical models.

Application of functional circuit training for women
TOMANDLOVÁ, Markéta
: The goal of this thesis is to introduce functional circuit training to the public and provide proper information, outline the present state of group lessons and also diversify and describe the differences between male and female trainings. The theoretical part composes of the analysis of relevant literature. The practical part is made up of creating an intervention motional program targeting women aged 20 to 25, which was applied for three months on 5 respondents in the specified age range. The next 5 respondents stood for a control group to serve for later reassessments. Our research accounted for four presumptions: After completing the intervention motional program, there is decrease of bodyweight in women, decrease of the percent of body fat, decrease of waistline and better Body Mass Index. The research was evaluated based on the comparison of the results in the beginning, in the middle and at the end of the intervention motional program. The results show that after application of the interventional motion program reducing the percentage body fat ratio of at least 0.5% fat for each respondent from the experimental groups. For each respondent, the experimental group was also a significant reduction in waist circumference and a minimum of 1 cm in each. As a result, we can recommend the program to other women who decide to lose weight and improve their bodies. Also, owing to vast publications on the topic of functional circuit training and the ambiguity established by incompetent information sources, this thesis will surely be an asset to coaches and women who are interested in functional circuit training.

Advanced Visual Telepresence System
Davídek, Daniel ; Kopečný, Lukáš (referee) ; Žalud, Luděk (advisor)
The introduction of this document presents some basic principles of visual telepresence with analysis of important aspects of the design. Afterwards there is a brief ovrewview of some of the applications of telepresence systems. Subsequently there is a description of the basic parameters and functions of the human visual perception system including the head motion parameters. This document examines the creation of telepresence apparatus through which is the user able to percieve visual stimuli accross distance. The device consist of camera with wide FOV positioned on the last link of the servo-motor chain with 3 DOF. Camera view is projected into scene in position read from actual motor posture. The scene is perceived through the HMD Oculus Rift (DK1, DK2) where the actual head-orientation read from the HMD inertial sensors is the entered end value for the rotation angles of the servomotors. A \csharp (WPF) program was developed for the controling and setting of motors which handles the byte communication through RS485-USB converter and also configures and starts the telepresence mode. The telepresence scene is drawn with help of SharpDX and SharpOVR - the \csharp wrappers of DirectX and LibOVR.

Control of the Mini-Swing manipulator
Ráheľ, Dušan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
The diploma thesis deals with control of robotic manipulators and their range of applicability. The main objective is to create kinetic model of manipulator in the SolidWorks environment and to set up the identification and control program in the LabVIEW software. It evaluates the applicability of SoftMotion Module tool, which was developed especially for the model control in Motion analysis. The proposed method of control is used on the kinetic model, which employs control commands for the movement of manipulator MiniSwing

Dynamic analysis of oscillations with multiple degrees of freedom
Schulmeister, Jiří ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of oscillating with multiple degrees of freedom and with example of dynamic behavior of system with two degrees of freedom with different input signals for purposes of dynamic lessons. Conventional method of making equations of motion by Lagrange’s method and their consecutive analysis is inscribed in the work. As example of system with two degrees of freedom is chosen quarter car model. Responses to different input signals are shown for the model. It is made in MATLAB/SIMULINK.

Trailer frame PILLAR for transport concrete pillars
Urban, Jiří ; Kašpárek, Jaroslav (referee) ; Kašpárek, Jaroslav (advisor)
The aim of this thesis is an analysis of the construction of a trailer used for transporting concrete pillars. The main part of the thesis is focused on frame construction. For the calculation of load states a multi body system was used, whereby a simulation of transport in terrain was performed. The results from these calculations will be used as limiting conditions for strength control. The method of solution is the finite element method. All acquired results will be analysed and according to them changes will be made to the frame construction. In addition to this, the thesis contains drawings documenting the above-mentioned changes.
