Analysis of the structural joints of the disc tiller
Smola, Tomáš ; Dzimko, Marián (referee) ; Brandejs, Jan (advisor)
The aim of this diploma thesis is to analyse loading forces which impact on the frame of the disk plough-harrow during the real operation, suggestion and assembling of the measuring system for measuring of real loading. On the basis of this measuring to accomplish structural deformational tensor analysis of the frames load-bearing’s machine. In the introduction is shortly described using of the disk plough-harrow in modern agriculture. The diploma thesis is divided into two parts. The first part is devoted to the suggestion of the measuring system and loading measuring under real working conditions. The second part is focused on deformational tensor analysis of the frames load-bearing’s machine through the method of final elements. In conclusion it follows the evaluation of gained pieces of knowledge.

Characterization of sensitive nanomaterials for MOX gas sensors
Priščák, Juraj ; Gablech, Imrich (referee) ; Chmela, Ondřej (advisor)
This thesis deals with one-dimensional (1D) and two-dimensional nanomaterials (2D) in terms of their utilization for new types of gas sensors. Thesis focuses on study of sensing elements for gas sensors based on semiconductor metal oxide materials (MOX) and their manufacturing technology. The objective of the thesis is the design and implementation of a sensing elements formed by selected nanomaterials based on the structure of interdigital electrodes. The result of the practical part of the thesis is the characterization and comparison of materials in terms of their detection parameters in the presence of selected test gases. The first part of thesis hierarchically defines chemoresistive gas sensor, characterizes and explains its operation principle. Second part studies 1D and 2D nanomaterials of sensing elements for MOX chemoresistive gas sensors, contains a research of their properties and describes their methods of manufacturing and implementation. The last part deals with the implementation of the sensitive layer of the sensor with selected nanomaterials, characterizes and compares their detection properties.

Application of the Universal USB Module LabJack
PŘIBYL, Vojtěch
This thesis describes applications of general-purpose USB module LabJackTM. This thesis acquaints with individual measuring modules by LabJackTM Company. It describes the selected modules LabJack U12TM and LabJack U3-HVTM at great length. This thesis contains selected themes acceptable for the application with modules LabJackTM and selection and implementation of sensors usable in selected themes. In this thesis is the signal way through measuring chain from sensor of physical quantity to final signal evaluation through the software eSimLab in detail described, propounded, in practice implemented and checked by measurements.
