Barrel Rifling Machine Designe and Function Analysis
Loutocký, Petr ; Hammer, Miloš (referee) ; Jankových, Róbert (advisor)
This master’s thesis is devoted to rifling technologies of the barrel bore of fire and gas arms. In cooperation with the company Winston Production, s.r.o. also enters into operation issues of selected manufacturing machine Zs 151 for barrel rifling. It contains an analysis of legislative demands on the technical documentation, description of the construction and function of machinery and materials for the creation of local operating safety rules for its operation. The part of work is also 3D model of the machine created in software SolidWorks.

The determination of the route for running footraces by a modification Travelling Salesman Problem
Havel, Filip ; Borovička, Adam (advisor) ; Fábry, Jan (referee)
This diploma thesis deals with finding the optimal route for running footraces. This work seeks to find a link that determines a lap with a predetermined beginning and a goal at the same time, given the possibility of 251 intersections. This model is derived from the travelling salesman problem, whose primary task is to pass the specified set of places according to the shortest route or in the shortest possible time and to return back to the starting point while visiting each place only once. Of course, the routes searched for in this work may be differentiated in several aspects. First of all, it is not necessary to include all of the places you can visit multiple times. The resulting route does not have to be the shortest, but it should have a certain span of distance, as the height metrics obtained are the key factor for optimization. A solution with the exact methods will be demonstrated by the LINGO optimization software, but only for a higher computational difficulty with a limited range of tasks, 21 junctions in the city center. Determining a longer route on a larger set of intersections will allow for derived heuristics with working names: the furthest neighbor with the smallest ascent and a minimal profile change. Part of the thesis is a detailed description of the mathematical model used, the general procedure, along with both a demonstration and an analysis of the applied heuristics.
