The MEMS sensors usability for position detection
Bobalík, Lukáš ; Sedláček, Jiří (referee) ; Žák, Jaromír (advisor)
Within this Master’s thesis, design and construction of a strapdown inertial navigation system based on MEMS sensors is described. The thesis includes theoretic analysis of physics behind determining the position of an object based on the object’s aceleration and changes in the object’s orientation in space. Included is also an overview of mathematical methods related to the position calculation.

Position navigation system with GSM interface
Pristach, Marián ; Khatib, Nabhan (referee) ; Kadlec, Jaroslav (advisor)
The objective of the diploma thesis is to design a device for positioning of mobile devices using GPS satellites. When coordinates are acquired they can be sent via the GSM network to a user's cell phone or to an SQL server. A web interface has been designed to access the stored data and to show the current device position and the history. This position datalogging system can be used for monitoring vehicles as well as a security system for cars.

Research of Localization Algorithms in Wireless Sensor Networks
Holešinský, Pavel ; Morávek, Patrik (referee) ; Šimek, Milan (advisor)
This diploma thesis is focused on research of localization algorithms. Each developed localization algorithms are generally application specific. Because of application requirements diversity, many variants of localization algorithms exist. In case of finding appropriate localization algorithm for concrete application usability, existence of real condition simulation environment is useful. Development of this simulation environment was made simultaneously with both localization algorithms. At first, survey of available localization technic was performed and their summary was listed. Further work was aimed on research of two localization algorithms. Both of them use triangulation mechanism to determine unknown node position. This mechanism is based on measurement of distance to three reference points with known position. It would seem that both algorithms are similar, but simulation shows their difference and presents their suitability for diverse conditions.

Welding Basic Course on 135 Technology
Dolejský, Tomáš ; Opletal, Jan (referee) ; Kubíček, Jaroslav (advisor)
TOMAS DOLEJSKÝ: Welding Basic Course on 135 Technology. The project developed within the framework of the bachelor's study of a branch Engineering technology presents a proposal for a theoretical and a practical parts of the welding basic course with a method 135 in accordance with the curriculum of Czech Welding Society-ANB. The latest norms or up to the present time still valid ones are presented in the project. A theoretical part contains a necessary minimum of requirements for participants of the welding basic course. In the chapter of a welding technology is presented a practical part of this welding process and important principles for a required quality of welded joints according to long-time experience. In a conclusion there is an interpretation of a norm ČSN 05 0705 according to what welding basic courses are realized and a welding process WPS is presented here and a proposal of examining tests for a passing an exam in a welding basic course.

Realization of educational problem based on experimental apparatus with cam mechanism
Tomeček, Vojtěch ; Vrbka, Martin (referee) ; Vaverka, Michal (advisor)
Bachelor's thesis is focused on solving educational problem based on experimental apparatus with cam mechanism. The task of the educational problem is to teach students to analyse kinematic quantities of cam followers. The thesis contains general discourse on the topic of cam mechanisms and basic terms definition. This is followed by putting the device into service, eliminating its particular imperfections, analysis of kinematic quantities of various combinations of available cams and followers and definition of methodics of the educational problem. The educational problem itself follows the presentation and commentary of gained results. At last some recommendations for the future modifications of the experimental apparatus are given followed by foreshadow of its eventual future usage.

GPS data usability in mobile robot navigation problem
Novák, Pavel ; Věchet, Stanislav (referee) ; Krejsa, Jiří (advisor)
This work is focused on problems of the GPS/DGPS receiver precision used by mobile robot for navigation in outdoor environment. The first part deals with theoretical analysis of GPS, description of it´s functions, errors and their influence on measurements accuracy. Second part deals with practical measurements performed at two locations with different types of obstacles restricting the view to the sky and using the refining methods of measuring the DGPS or so-called differential GPS. The last part of study presents the measured results and its analysis.

City apartment house Klíčova
Foltýnová, Michaela ; Mléčka, Jan (referee) ; Šindlar, Jiljí (advisor) ; Krupicová, Jana (advisor)
New city apartment house is located in the center of Brno, incorporated into older apartment buildings on the Klíčova street and partly on the Zvěřinova Street, near the Křenová street, Olomoucká street a Tržní street. It is a monolithic reinforced concrete skeleton, founded on piles, with five aboveground floors and one underground floor, finished by a flat roof. The house is separated by four entrances to units. Each of these units contains a specific type of flat and house is fully wheelchair accessible. In the house there is a underground parking, service areas and flats. Behind the house there is a recreational area for residents of the house. This house is interesting because of interior design and attractive location, especially thanks to the position in the city center, easy accessibility and pleasant surroundings near the river Svitava and a adjacent alley.
