Using of accurate capacitance bridge for inductance measurements
Uher, Miroslav ; Ševčík,, Karel (referee) ; Havlíková, Marie (advisor)
This master’s thesis is dealing with possibilities of measurement of inductance by using of accurate capacitance bridge AH 2500E. In metrology there are no appropriate devices available for accurate measurement of inductance. It can be realized by four methods. The newest one is based on T elements, it is not used for this purpose yet and it is practically investigated in CMI Brno. For its introduction to practice it is neccessary to complete computer simulations and analysis of influences affecting measurement. It is also inevitable to examine repeatability of measurement, define methodology of measurement and potential corrections of measured values.

Multimaster communication over long distances
Hedvíček, Michal ; Málek, Petr (referee) ; Uher, Miroslav (advisor)
This bachelor project deals with a theoretical analysis of employed serial buses and a comparison of their qualities especially with regards to a medium-range distance. Also, it considers the possibility to extend I2C-bus by special circuits, which guarantee communication for longer distance. Next deals with measuring draft program for the collection and evaluation of measurement data. Following measurement itself and evaluation parameters of signal on the bus under different conditions.

Automation of climatic data acquisition
Sádovský, Petr ; Benešl, Tomáš (referee) ; Uher, Miroslav (advisor)
This bachelor´s thesis deals with the design of a measuring system for a datalogger´s COMET S3120E battery. Also about the replacement of the existing communication cable between the datalogger and the PC. After a basic analysis of the task and description of the given components on which the design is based, a system is designed that not only ensures communication but also controls the charging and control of the datalogger´s battery. After the design, an estimate of the possible measurement error is made, which is carried out with the help of measurement uncertainties. Finally, the software solution and comparison of the resulting measurement with estimates are described.

Automation of climatic data acquisition
Sádovský, Petr ; Pikula, Stanislav (referee) ; Uher, Miroslav (advisor)
The goal of this work is to understand and identify the communication of the COMET S3120E datalogger. Subsequent design of a circuit solution that will allow two-way communication with the datalogger and the compilation of control software for the PC. The basis of the work is a theoretical and practical part. In the theoretical part of this document is a theoretical description of the functionality of the datalogger and its components. It also contains a description of the software used to achieve the goals. The las part deals with circuit design and software for PC.

Automation of access to test files for the vibration system
Dolobáč, Dávid ; Richter, Miloslav (referee) ; Uher, Miroslav (advisor)
The aim of this thesis is to analyse structure of test files used in vibration tests in the CVVOZE testing laboratory and to design and implement a software solution that ensures automation of access to these files. The proposed software solution in the form of a desktop application completely automates the original manual entry and acquisition of test data using the created SQLite databases and provides the test technician with an alternative to the existing RMS software.

Measurement uncertainties in calibration of vibration sensors
Pražák, Jiří ; Uher, Miroslav (referee) ; Šedivá, Soňa (advisor)
This thesis deals with the research of uncertainties of the vibration sensor calibration measurement. The analysis of individual calibration methods of vibration sensors is also carried out in this thesis. Next, measurement of uncertainties for secondary calibration of the vibration sensors are analysed. The experimental part of this work is focused on determining the influence of different elements to type A uncertainty of vibration sensors uncertainty calculation. Experimental measurement was performed in an accredited laboratory for measurement and calibration of vibration sensors at FEEC BUT. Calculation of uncertainties of secondary calibration is also carried out in this thesis.

Granulometry of solid particles
Klimeš, Jiří ; Uher, Miroslav (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with a real-time granulometry measurement of granulate flow with acoustic emission sensors. Thesis is focused on coal granulometry measurement in thermal power stations. Parameters were introduced in time and frequency domain describing the granulometry of measured medium. The second part is focused on granulometry measurement experiment. Parameters were calculated for reference samples of material and they were evaluated. Third part of this thesis deals with finding correlations between process variables and selected parameters

Software interface for database files
Novák, Adam ; Boštík, Ondřej (referee) ; Uher, Miroslav (advisor)
The bachelor thesis deals with the way how to access database files with the extension (* .shk), (* .sin) and (* .rau) based on Microsoft Acces 2.0. Document these files and create a software interface. The interface creates the given types of database files. Uploads measurement settings to RMS device measurement files. After the measurement, it extracts data from the database, which can then be further evaluated.

Power Supply Testing
Chládek, Petr ; Uher, Miroslav (referee) ; Beneš, Petr (advisor)
This project is about testing of power supplies with the electronic load Agilent 6063B. There are described parameters of power supplies and methods of measurement using the electronic load Agilent 6063B. The measurement process will be automated by using a program created in an environment LabWiew.
