Description of outside grinding machines
Brychta, Tomáš ; Opl, Miroslav (referee) ; Blecha, Petr (advisor)
In this bachelor’s thesis is completioned background research and outside grinding machines description.In the introduction of this thesis are shown the aims which will be reached while elaborating. This thesis includes general introduction about grinding, where is mentioned definition of the grinding, description and grit distribution on grinder, parametres of grinders, reached geometric accuracy, reached surface roughness, cross section of cuttings, definition of the main and alternate movement and cutting conditions on the tool and on the workpiece at grinding.Furthermore general partition of grinding machines types, view and the parting of the grinding machines producers, with the references to their web sites and with data about country of origin for each of these producers. After it the thesis focus only on outside grinding machines and in their division. In centre grinding machines is shown their division and characterictics, ways of grinding and description of each way and there are shown producers of centre grinding machines with concrete tips of machines too. In each of this machine are shown its preferences and engineering characteristic. In profile grinding machines is shown its characteristic, producers of profile grinding machines and tips of these machines. In surface grinding machines is shown characteristic of surface grinding, the partition of the surface grinding machines, ways of grinding and description each way, producers of these grinding machines and tips of separate machine with its preferences and engineering characteristic. The last type of the outside grinding machines are centreless grinding machines. There is shown characteristic of centreless grinding, ways of grinding and the description each of the way, producers of centreless grinding machines and tips of these machines with its description and engineering characteristic. By the centreless grinding are shown even the ways of double disk grinding with the examples of utilization this grinding. The work is ended by finish, where is shown overall assessment in the way of grinding machines development, resources and innovations, which the producers using to increasing precision of the machines.

Additional Load Elimination at Suspension Components Testing
Brychta, Tomáš ; Porteš, Petr (referee) ; Ramík, Pavel (advisor)
The thesis first provides a survey of acceleration tests with the focus on automotive component testing. The survey covers multiple types of acceleration tests and sources of stress. The thesis then includes a MATLAB application for the removal of inertia forces, which is applied on two shaft configuration models developed in Pro Engineer. Both models are subjected to stress analysis using FEM in Ansys. The thesis has been carried out in collaboration with TRW-DAS Dačice.

Wireless Sensors for Smart Home
Brychta, Tomáš ; Viktorin, Jan (referee) ; Korček, Pavol (advisor)
This thesis deals with sensors for wireless communication in smart homes. The task of sensors is to establish connection with controlling unit through which the measured data will be sent using defined application protocol. The work analyzes in detail the influence of interference on this communication and offers solutions of eradicating this interference to improve stability of communication itself. As a prototype for sensor device we used development kit from Microchip company.

Legal aspects of land consolidation
Brychta, Tomáš ; Franková, Martina (advisor) ; Pokorný, Jiří (referee)
Since the second half of the 19th century the land consolidation has been carried out as an administrative proceeding in the territory of the Czech Republic. As a result of a gradual development, the scope of land consolidation is becoming broader and goals of the proceeding are becoming more and more ambitious. What issues can be solved using land consolidation and which instruments are used to accomplish that? How do public and private interests affect the land consolidation and parties to the proceeding? What is, or rather what should be the course of the land consolidation proceedings? Are measures adopted in the proceeding actually being implemented in the landscape? Submitted master's thesis draws attention to substantive and procedural aspects of the matter, relevant case law, as well as statistical data and other evidence regarding concluded land consolidation. The first part of the thesis deals with historical development of land consolidation, focusing on the 19th and 20th century. This chapter aims to allow for a better understanding of the basis of the effective legal regulation, which adopts some former concepts, while firmly abandoning others. The second part represents a first introduction to the effective legal framework of the land consolidation. Using statistical data this chapter...

Physiological aspects of body composition measurements
Větrovská, Renata ; Matoulek, Martin (advisor) ; Poledne, Rudolf (referee) ; Brychta, Tomáš (referee)
Determination of body composition or amount and decomposition of body fat belongs to the basic clinical examination of an obese patient. But methods used to determine the amount of fat in obese population are often innacurate. And it's adipose tissue and its measurable parameters which can provide us range of information for the further process of the reductive treatment. The main goal of this work is to evaluate the physiological aspects of body composition measurement in several areas: (I) To determine whether the values of body fat measured by most commonly used methods are comparable to those measured by method DEXA. (II) To determine whether the values of the amount of body fat measured by different methods vary depending on the amount of BMI and adipose tissue in the body and assess whether the available bioimpendance methods can measure the functional state of body fat. (III) To assess the resting energy expenditure in relation to body composition and physical activity. (IV) To determine whether the body composition will affect the resulting reduction after excercise program for women with overweight and obesity. (V) To verify whether changes in the values of BOHB (Beta Hydroxybutyrate) after physical activity could be the predictor of weight losses and changes of body composition. Based on...
