Study of sensoric properties of organic semiconductors
Saska, Pavel ; Šedina, Martin (referee) ; Salyk, Ota (advisor)
Compounds based on diketopyrrolopyrrole are organic pigments that behave as semi-conductors. Their analogues with pyridyl side group are due to their sensitivity to hydrogen potentially useful as hydrogen sensors. The aim of this work was to examine properties of sensors with an active layer of diketopyrollopyrolle derivatives. The sensors were tested on an apparatus built for this purpose at FCH VUT in Brno. More specifically, changes to conductivity of these sensors in the presence of hydrogen under various conditions were studied.

Software for control of the velocity probe manipulator
Balusek, Radim ; Věchet, Stanislav (referee) ; Houška, Pavel (advisor)
The aim of this work is to create control software for the manipulator with three degrees of freedom used for measuring the temperature field and its activities to verify the model. Control manipulator is designed in the NI LabVIEW program. Furthermore, the work deals with the addition of the sensory system manipulator Swing. Part of this work is a description of the elemental characteristics controlled manipulators and the problem of their control is analyzed there. The practical part describes the structure of the proposal and its simulation software to verify the model.

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.

Evaluation noise empty weight in running processing vegetables.
KALKUŠ, Václav
This Bachelor´s thesis paper describes the evaluation of machinery noise stress in vegetable manufacturing facilities. Furthermore it explains the construction characteristics and production technology in vegetable manufacturing. The aim of this paper is to meassure the levels of noise during all work processes in the shredding room. Moreover, the goal is to process the meassurements and analyze the minimums, maximums and equivalent noise levels, while using appropriate formulas. These calculations will be then compared with the current hygienic norms. In case, the meassurements exceed the norms, a corrective proposal will be suggested to improve the situation.
