Alternative measurement of shape and position deviations for needs of incomming inspection.
Jaša, Aleš ; Pernikář, Jiří (referee) ; Zemčík, Oskar (advisor)
This thesis deals with a possibility how to make a check of purchased components faster at the incoming inspection of the Bosch Diesel s.r.o. (Co., Ltd) and perhaps even how to save investment in new machines during expanding of production without quality compromises during the check itself, so that everything would proceed according to ISO/TS 16949 standard, valid for an automotive industry. The whole practical part has been elaborated on the basis of measurements done at the incoming inspection measuring laboratories and in cooperation with QMM1.2 department. The results have been evaluated by statistical software qs-STAT ME 6 by Q-DAS company.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Measurement of three-wire transformer parameters
Kováč, Frederik ; Bukvišová, Zuzana (referee) ; Wasserbauer, Vojtěch (advisor)
Thebachelor’sthesisdealswithmeasuringsymmetriccomponentalimpedanciesofthree winding transformer. Thesis is divided into a theoretical and practical part. In theoretical part is described principle of transformer operation, its parameters, open-circuited and short-circuited measuring, measuring of zero-sequence impedance and connection schemes. Practical part deals with design of workplace in laboratory, description of used instruments and practical measurements with real connection schemes. For measuring parameters of three winding transformer is created a laboratory instruction manual.

Documentation of the church in the Dolní Věstonice village
Kovářová, Anna ; Vondrák, Jiří (referee) ; Kratochvíl, Radim (advisor)
The purpose of this thesis is the creation of documentation of the St. Michael the Archangel church in Dolní Věstonice village, which includes topographic situation of the object, drawing of the first floor, vertical and longitudinal sections and outdoor views of the façades. The church, it’s location and chronological description of all activities is included in the text of the thesis. Chapter named Preparatory work describes reconnaissance of current point field, creation of network of extra points for measuring and sketches preparation. The next section describes the methods used for positional and height measurement of detailed and assist points. The following chapter entitled Office work includes description of all the calculations and the making of individual drawings. The summary of results and the possibility of future use of the created documentation is described in the end of this thesis. All drawings, calculations reports and the accuracy testing of detailed points are found in the annexes.

Spectral analysis of sound in spatial acoustics
Křenek, Jakub ; Čížek, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is focused on the basics concepts of room acoustics and used sound level meters. The first part focuses on the spatial acoustics and acoustic quantities used in it. Next part of thesis describe the structure and features of sound level meters. Following chapters are concerned on the PULSE system architecture and data analysis. PULSE platform contributes multi-spectral analyzer type 3560B PULSE, programming environment LabShop and microphones for difuse and free fields. The practical part describes the installation, setup and the measurement of reverberation time in the Labshop environment.

Smart hydrogen sensor
Kašpárek, Petr ; Pavlík, Michal (referee) ; Boušek, Jaroslav (advisor)
The main goal of this diploma thesis is to get familiar with organic sensors developed at the Faculty of Chemistry at Brno University of Technology. The outcome is the implementation of smart hydrogen detector which is based on use of these sensors. This device will allow to test and use relevant sensors outside the test apparatus placed in the laboratory of the Faculty of Chemistry at Brno University of technology.

Temperature Measurement in Technical Diagnostics
Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.

Microprocessor controlled testing unit
Mejzlík, Vladimír ; Tošovský, Petr (referee) ; Kolouch, Jaromír (advisor)
This project deals with the design of an autonomous microprocessor controlled testing unit for automatic controlling the output of the tested device, depending on the excitation of its inputs. There are possible realizations of testing unit hardware functional blocks described. Possible options are objectively analyzed in accord with the project specification and with regard to the mutual compatibility of individual blocks, availability, price and desired functionality. The most appropriate selected solution is implemented using the specific circuit elements. The output of the project is realized functional testing unit and elaborated product documentation. There was control software for the microprocessor of the unit written. The software implements an interpreter for the test algorithm execution, carries out the test evaluation and stores a record of the test process to the file. There was also the utility for a PC, which allows uploading tests to the testing unit via USB created.
