The influence of PVD coating on tool life of cutting inserts during face milling
Jašek, Petr ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This diploma thesis is aimed on durability of PVD and CVD coatings for symmetrical face milling. The theoretical part describes the characteristics of cemented carbides, milling technology and the characteristics of the coating methods. The experimental part describes the machine tool, used tools, workpiece material and cutting conditions. The aim of the work was to measure the cutting forces and tool wear during the milling. Based on experiment, it is clear that the PVD coatings with nano-layers achieves to the longer life in comparison with others and generally, that the using of coatings leads to reduction of cutting powers and lifetime was increased.

Network Game: Destroy the Submarine
Jašek, Petr ; Mlích, Jozef (referee) ; Szőke, Igor (advisor)
This Bachelor's Thesis describes development of a simple network computer game. This thesis describes basic scheme of computer game development. Also an analysis of various implementation of network is made in this thesis. The output of this work is a computer program written in the C++ language. For implementation of the network the Boost 1.50.0 library was used. Network communication was implemented as client-server architecture with usage of the UDP protocol. For implementation of graphics and sound, the Allegro 5.0.7 library was used.

Passive sensors for detecting instantaneous stress and strain values
Jašek, Petr ; Kandus, Bohumil (referee) ; Podaný, Kamil (advisor)
Technical measurements are an indispensable source of information in the technical fields. Due to the computer processing it is necessary an electrical signal as the output of the sensor. The field of measuring techniques of non-electrical quantities comprises a wide range of various sensors. Passive sensors represent an important group, into which resistive, inductive, capacitive, magnetic and ionization sensors are arranged. Basic findings of measurement are presented, and particular kinds of sensors, their functional principles, application examples and evaluation of their properties are described in the thesis.
