System of On-/Offline temperature measurement based on Lab View
Stejskal, David ; Hammer, Miloš (referee) ; Prostredník, Daniel (advisor)
The objective of this thesis was to create a LabVIEW-based program for temperature measurement using a personal computer. The program allows reading and post processing of digital signal from a measuring device. This device consists of a sensor type PT100, a measuring transducer and an analog-to-digital converter with USB output. The theoretical part of the thesis deals with resistance temperature sensors, signal analysis and methods for signal processing. The practical part is conceived as a guide to the created program. This part introduces vital sub-elements of the program and describes their principle, practical use and also the operating instructions. As required by thesis assignment, practical part includes verification of the measuring device, which was performed in laboratory of Czech Metrology Institute in Brno.

Noise Generator Diagnostics
Plucková, Iveta ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with noise diagnostics of the generator. The practical part of the thesis is realized in the Dukovany Nuclear Power Plant. The first part of the thesis, noise is generally discussed. The quantities and their measurements are described, quite generally, also for the given company. According to specific conditions in the Dukovany Nuclear Power Plant, there is a distribution of noise measurements, which is carried out by an external company. The work gives a concrete example of this measurement. At the end of the work, the practical measurements of noise were done for selected generators, which were realized by an author for the purposes of this bachelor thesis. The experiment is evaluated.

Predictive machine tools maintenance system with the use of vibrodiagnostics
Semotam, Petr ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
This diploma thesis concerns issues of predictive and condition based maintenance system of machine tools with using a vibrodiagnostics. It studies and researches its impacts through the basic processes of the maintenance system and characterizes the vibration diagnosis as its tool and mean. There is also described a process of putting condition based maintenance into practice in the practical part of the thesis. The development is realized at Siemens Ltd. Brno with all its requirements and aspects such as a maintenance audit which means the decision on the suitability of condition based maintenance within the current maintenance system, technical analysis as a part of introduction of vibration diagnosis and the practical example of acquiring, recording and assessment of measured vibration. Prior to the end the economic evaluation of the planned predictive maintenance system and the design of the general model of development and implementation of the maintenance system into practice are included.
