Optimization of welding parameters during laser welding with additional cold wire
Venc, Jan ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
This diploma thesis deals with the optimization of process parameters of welding a drainage channel using a laser beam with an additional cold wire. This channel is made of austenitic Cr Ni stainless steel X5CrNi 18-10 (1.4301, ČSN 17 240) with a sheet thickness 1,5 mm. Mechanical properties of samples were checked by using transverse tensile test. Subsequently, the samples were macroscopically inspected focusing on dimensions of the weld and the presence of weld defects. Finally, the structure of the weld metal and fundamental material was evaluated by using microscopic control. Based on evaluation tests, the optimal welding parameters were recommended.

Design of the trough with respect to hygienic requirements
Venc, Jan ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of a hygienic trough. The trough is made by the company ACO Industries k.s. from stainless steel 17 349 of thickness 1,5 mm. Literary studie is focused on respect to hygienic requirements, which are defined by EHEDG. The trough was valorized and necessary adjustments were proposed to meet the conditions. Based on proposed profile and on the main volume makes custom production, was selected Bending as the most favourable technology for construction and WIG method for welding.

Crime of murder and manslaughter under section 140, 141 of the Criminal Code
Venc, Jan ; Hořák, Jaromír (referee)
Crime of murder and manslaughter under section 140, 141 of the Criminal Code Abstract This thesis is focused on crimes of murder and manslaughter under Act No. 40/2009 Coll., Criminal Code. The aim of the thesis is to deliver a complex analysis of crimes of murder and manslaughter under section 140, 141 of the Criminal Code and evaluate them de lege ferenda. The thesis is divided into five chapters. The first chapter is dedicated to the historical development of intentional killings regulation in the premises of today's Czech Republic. In particular, the attention is brought to the Austrian Penal Act from 1852 all the way up to the adaptation of the present Criminal Code of the Czech Republic. The second chapter is focused on actus reus of the crime of murder and manslaughter. Both of these crimes are of special significant object - the human life. This chapter's focus is also dedicated to the beginning and the end of human life from the perspective of criminal law. The third chapter focuses on the analysis of the crime of murder and its systematization under the present Criminal Code. Within this chapter, the simple murder and premeditative murder are outlined from which is murder with forethought and murder after prior consideration further defined. The significant part of this chapter is the description...
