Unconventional Metals Hardsurfacing Technologies
Krejčí, Vojtěch ; Šárka,, Šimůnková-Houdková (referee) ; Čelko, Ladislav (advisor)
The main objektive of the bachelor thesis is to evolve problems of metalic surface welding and to implement the basic partition of the most expanded used technologies of surface welding. Sometimes we can see the term deposition metalic surface welding too but in practice is used technical term metalic surface welding. The introdution includes the basic acquaintance with problems and the characterization of the proces of surface welding including the summary of its advantages and disadvantages. In other chapters we aim on individual technologies of surface welding, its principle and using in technical practice. Simultaneously is worked out the overview of already unused or minimally used technologies of surface welding. After the presentation of individual technologies follows the section dealing with partition of materials used for surface welding by the basic material as well as surface welding materials at the present technical practice. In the experimental section of thesis follows selected examples of using the presented technologies of surface welding in practice at present.

Usual time and frequency of mirrors and dashboard observation by the driver
Krejčí, Vojtěch ; Sedlák, Robert (referee) ; Bradáč, Albert (advisor)
The thesis deals with the analysis of the usual time and frequency of vehicle mirrors and dashboard observation. Within the theoretical part are summarized the current knowledge of the visual distraction of the driver, or circumstances which affect the conduct and behavior of the driver while driving. Furthermore there is a closer approximation and characterization of devices for recording the driver's eye movement, which is used during the measurement of the usual time of observation. This data is used in the experimental part of the thesis. The results were processed and statistically analyzed to determine the usual time of mirrors and dashboard observation. Conclusions done from the measurement results are contained in the last chapter, which also evaluates contribution of this work to practical use in the field of analysis of road accidents and to improve safety on our roads.
