Durability testing of replaceable inserts in cylindrical turning of carbon steel
Smolík, Martin ; Vítek, Jiří (referee) ; Sedlák, Josef (advisor)
The thesis deals with the problems in the field of durability testing of replaceable inserts for longitudinal steel turning. The main objective of the thesis is the analysis of the cutting process based on the results of the performed cutting tests. The cutting tests will be carried out comparatively by testing pairs of inserts, compared to each other. Wear observation is carried out by optical method using a workshop microscope and special software designed to process the acquired images. The output of the work will be an illustration of the different behaviour of the standard and the upgraded set of cutting inserts under different configurations of cutting conditions. The work provides a comprehensive view of the cutting tool testing process and quantifies the degree of influence of the various factors entering into the cutting edge wear process.

The complex solution of partial section of cyklo-trail "Otava cyklo-trail" Sušice - Riverheads of Vltava.
FRAŇKOVÁ, Lenka
Foundation ``Jihočeské Cyklostezky`` has, together with other towns, started to develop project of cycling trails constructions in the Czech Republic with possible connection to the Bavarian side. One of the partner towns is Sušice in the region of Klatovy, where the net of cycling trails and cycling path is not much spread yet. Due to this fact a project of ``Otavská cyklostezka {--} Pilgrimage through the region of Karel Klostermann{\crqq} was set. My task was to elaborate a design of a concrete chosen section of the cycling trail with solution of the individual sections. Summarization of map materials, solution of owner-law relations, construction interventions to the given roads, landscaping and other adjustments, directional and altitudial solution of the trail, intervention of the environment and other protective zone, but also careful solution of trail equipment (rest-picnic areas, information panels, bicycle stands, etc.) and traffic signs of the Otavská cyklostezka. Thank to the fact that the trail follows a current earth road, there were no problems with building estate. There will only be construction adjustments of these plots and adjustments of field and forest paths. Project documentation is elaborated for the building permission issuing according to the valid laws and norms.

Comparison of trucks of selected power range
Effenberk, Jan ; Šařec, Petr (advisor) ; Balada, Ivo (referee)
The main purpose of this bachelor thesis is to compare semitrailer trucks made by major European manufacturers. Maximum engine power of compared vehicles is limited to 340 kW. Secondary aim of this thesis is provision of theoretical knowledge of key mechanisms and issues of modern trucks. The thesis is devided into two main parts. The first one includes history and development of road transport and trucks. Basic technical terms and legislation are described there as well. Following chapters are dedicated to brief characteristic of mechanisms and their types. The second part of this thesis focuses on truck comparison according to selected parameters using chosen method of multi-criteria analysis. The thesis is concluded with results evaluation, ranking of each truck and discussion about certain issues.
