Method of measurement parameters in metal forming.
Knebl, Martin ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
This master’s thesis deals with the problem of measurement for thermomechanical parameters during metal forming under higher deformation rate. The first part works up general literary studies, comprising a summary of measurement methods for required parameters. There is described a principle of their function and usage. Further assessed the current situation and recommendation of appropriate methods for the dynamic processes of forming, especially their testing. The second part is devoted to the measurement for dynamic features of the material. This is a problem specified by Split Hopkinson preassure bar test. The test is described, including the mathematical evaluation process, in the theoretical part. In the practical part, there is a detailed description of the process and evaluation of the real test with aluminum alloy AlMg4, 5Mn ,07-EN AW 5083 performed within the framework of the junior project.

Application of robotic total station for crane tracks measurement
Chomjak, Ján ; Foral, Jakub (referee) ; Machotka, Radovan (advisor)
This diploma thesis deals with application of robotic total station for crane tracks measuring. To determinate straight of rail tracks was used system of automatic target recognition. One crane track was measured by two methods. Horizontal deviation from straight direction was determinated directly by the method “line of sight” and indirectly using measuring angles and lengths. To determinate height continuance was used engineering and trigonometric leveling. The results of measuring proved, that reached deviations between methods are minimal, so we consider them as equal. System system of automatic target recognition reliably and with sufficient accuracy aims to the prism-centre.

Side current channel of microprocessors
Obručník, Ondřej ; Hanák, Pavel (referee) ; Martinásek, Zdeněk (advisor)
In this masters's thesis is closely studied questins of current (power) side channel. It deals with attack upon this type of side channels and methods, which can this channel analyse. Also two methods of measurements, which make possible successfully attack, are presented here. Below the work describes progress, which was used for analyse current side channel of chip PIC16F84A. This chip, which was plugged in the circuit in agreement with diagram introduced here, processes step by step variety of programs implementing always other operation, which matches concrete used instruction. In corresponding chapters are introduced resulting values and graphs, which was obtained by measurement.
