Design and realization of the pull strength measuring device for SMD
Valíček, Jan ; Klíma, Martin (referee) ; Otáhal, Alexandr (advisor)
This thesis deals with the design and implementation of a device for measuring pull strength by surface mounted devices (SMD). It analyzes the theory of pull strength testing of solder joints with emphasis on standard IEC 62137-1-3 and describes the selection of components utilized to create mechanical construction and electrical parts. These electronic parts made or innovated in this work were control system based on microcontroler Atmega164P, power circuit for stepper motor and communication of measure equipment TEST 321 with PC. The whole design is complemented by simulation of mechanical stress to the critical components using ANSYS. The conclusion summarizes the most important parameters of this equipment.

Drawing
Kleinerová, Zuzana ; Franta, Jiří (referee) ; Mikyta, Svätopluk (advisor)
My artwork consists of a constant drawing research. I am focusing on a drawing process . I am trying to explain and show the process in the final drawing through the expression of lines. In the bachelor thesis I defined the drawing as a complex of lines subjectively perceived in the time. The entire drawing is an experience. To get closer to the present I started to solve single line. In the moment of its origin I feel the symbiosis between me and the line. I called it the line existence. The existential thoughts fill every drawing process. The act of drawing is a state of mind. I find myself in the place where lines cannot be captured. Just for a while i am able to feel, ,,live“ the line. The black matter is formed by emotions. The lines comes from my soul, my body.

Proposal of a program for solving of problems of simple tension/compression of bars and strut frames
Martínek, Tomáš ; Kubík, Petr (referee) ; Polzer, Stanislav (advisor)
The aim of this work is a program that will solve problems from the simple tension /compression bars and strut frames in the range of bachelor. The work consists of two programs developed in the Borland Delphi development environment. The programs allow the user to define a bar (strut frames) on the basis of the geometrical parameters and constraints, determine the rate of statical indetermination, make the necessary calculations and, if necessary, indicate the condition of deformation (a program for solving bars). The written part of the work serves as a manual.

Comparison of selected parameters of tensile strength of concrete
Rozsypalová, Iva ; Žítt, Petr (referee) ; Daněk, Petr (advisor)
The thesis deals with a comparison of the selected strength tension properties of the hardened concrete and finding relationships between them. This is essentially a simple tensile strength, tensile flexural strength and tensile splitting strength. The text describe the testing procedures to determine the tensile strength of concrete. Furthermore, there are presented the results of testing on different types of concrete (plain concrete, lightweight concrete, steel-fiber concrete, polymer-fibre concrete and high strength concrete). The conclusion deals with the derivation of dependancy between concrete strengths and comparing the values obtained from the available relations with the results of the tests.
