Digital spot-watch
Mejzlík, Vladimír ; Kolouch, Jaromír (referee) ; Michálek, Václav (advisor)
This bachelor’s thesis discusses options of realization of digital stopwatch with microprocessor line of MCS51. There are analyse different circuit variants, which might enable connection with microprocessor for achieve optimal result. The aim is design circuit solution and source materials for creation of functional prototype of digital stopwatch including development of service software. Verification of functionality and prossesing of achieved aims is part of solution.

Design of pendulum clock
Havránek, Jakub ; Sládek, Josef (referee) ; Křenek, Ladislav (advisor)
This bachelor thesis concerns with the design of the mechanical wall pendulum clock. This product should be characterized by the combination of glamour and reliability of the fine mechanics together with modern design language and high-quality materials. Author’s objective is to create the mechanical clock which would correspond to the contemporary design trends, taking up the old tradition of watchmaking along with being electrical power independent and taking advantage of the opportunity on the present-day markets.

History of automation and clock machines in Bohemia
Krajíček, Lukáš ; Zbořil, Miroslav (referee) ; Lacko, Branislav (advisor)
Clock makers were the inventors of the first automatic machines. This thesis deals with description of the mechanical clock machine housed in the church tower in Nová Říše, and documents the history of automation in Bohemia. The text describes the history of this clock, as well as difficulties that arose during its construction, as well as its maintenance and regulation. Information is also provided which pertains to the exposition of this clock at the Technical Museum in Brno.

The utilization of the individual gears for tractors higher power series
DRAHOŠ, Pavel
The aim of the bachelor thesis was to monitor the operation of two tractors with different transmission variants with a shift under full load and the group lifting under load, in terms of used gear at different working deployment (stubble, plowing, sowing). First, the literature review describes the historical development, construction and activity currently used tractor transmissions. The following is a description of the methodology of measurement and evaluation, bringing used calculation formula. Custom measurements were performed on tractors John Deere 7810 with transmission Powershift 19/7 and AutoQuad 20/20 and proved that in practise there are only using a few of the many gears installed. For a simple design optimization gears are used total tables extended with graphs for individual transmissions. Based on the measurement and after the data analysis is presented the proposal of transmission with 10 forward gears and 2 reverse gears with a fully stamped gears under load. Current manufactures and the market, however, now offer tractors with mechanical transmissions increasing amount of gears than in the past. Increasingly, the trend is promoting the installation of transmisson with the fluent change of transmission ratio to the current use of advanced contemporary electronic transmission control and engine tractor.

Mathematics and Sport
PALÁTOVÁ, Petra
The thesis elaborates on relations between PE or sports in general, and mathematics. The author focuses on a practical application of numbers on sports such football, swimming, track and field, downhill skiing and Olympic games. Moreover, the mentioned numerical methods are further used for writing a workbook of model exercises for grammar schools. The thesis is divided into two main chapters ? theoretical and practical. The theoretical part consists of selected sports which are expressed and described by numbers and formulas. In the practical part, a reader can find the workbook of model exercises which has been completed using all the mathematical sources discussed in the theoretical part. There are also correct solutions exercises available for self-studying students.

Webový informační systém pro SME
Hornof, Johan ; Pecinovský, Rudolf (advisor) ; Šlajchrt, Zbyněk (referee)
Nowadays, every single company needs to operate with large amount of data to support daily operation. Although there is pretty good market offer with information systems for managing various kinds of data, only small part of them is suitable for the company that does not deal with sale of goods but provides services, particularly marketing services or IT services (e.g. programming). This thesis describes the design and development of such a system which has a main goal to satisfy the needs of small to medium companies whose needs are still different than what currently marketed products can offer. Such a system will, apart from other functions, be able to manage projects and track work time of employees.

Measurements of selected physical quantities
ROLF, Tomáš
The purpose of this diploma work is researching the time measuring methods. I deal mostly with the historical development of the time measuring but I do not forget describe the present too. Next aim of this work is searching for the connection among three chosen quantities- time, energy, and entropy.
