Bending technology profile of steel
Kameník, Tomáš ; Žák, Ladislav (referee) ; Dvořák, Milan (advisor)
KAMENÍK Tomáš: Bending technology profile of steel The project has been elaborated within the master's of studies of the subject M-STG manufacturing technology and it presents the lay-out of the bending technology profile of steel from the material S235JRG2. The bend is made by the bending and the press tools. The press tools and the bending profile were suggested on the bases of the literature study of technology bending. In consideration of the calculated bending power and the dimension profile will be made profile on the hydraulic press CYS 320 ( the manufacturer ŠMERAL Brno a.s.). At the end of the the thesis there are performed calculations of the technical and economic evaluation for the machine press and the bending .

Longitudinal rolling
Sigmund, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis describes technology of hot-rolled profiles. It defines the conditions which must be fulfilled for successful process of rolling. Further is described process of producing a specific special profile, which is used as an intermediate for making car door hinge. The profile is made of structural steel S355J2. It is manufactured by VÚHŽ a.s., which uses reverse duo rolling stand with special work rolls. The thesis evaluates the usability, advantages, disadvantages and mechanical properties that are obtained after forming at high temperature.

Application for Tracking Devices for Windows Phone OS
Pupák, Juraj ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This application deals with recording of position about phone devices with help of system GPS. The application is implemented for platform Windows Phone 7.5. The Application allows to create profiles, which are evaluated with recorded positions. The evaluation is made through 2 points with Haversine formula. The theoretical part of thesis deals with technologies and GPS system, the practical part deals with design and implementation.

Safe-life extension program for ZLIN Z 126 and 226 airplanes
Jančář, Milan ; Juračka, Jaroslav (referee) ; Augustin, Petr (advisor)
This master's thesis discusses the possibilities of safe-life extension program for ZLIN Z 126 and 226 airplanes, which despite their age and long-end production are still widespread and popular not only in the Czech Republic. The age of these aircraft is also related to the fact, that some aircraft are already approaching its border life, so there is an interest for the longest possible technical and legislative airworthiness. As mentioned in my bachelor's thesis, during the existence of this model series, there was no major damage occurred, except for sporadic exfoliation corrosion of wing flanges. Experience with maintenance of this aircraft points to certain underestimation of the current 5500hrs lifetime and it is obvious to suggest possible steps to increase the current limit. The thesis is therefore considered in this context the possibility of producing new wing flanges made of another material, performed the calculation for wing fatigue exchanged with flanges and designed technological process of this exchange, so that ZLIN Z 126 and 226 airplanes can be safely operated in the future.

Rail materials and profiles in rail transportation
Svobodová, Anežka ; Kvarda, Daniel (referee) ; Galas, Radovan (advisor)
This bachelor’s thesis is focused on the issue of the choice of rail materials and profiles. The aim is to give a comprehensive overview of the current situation in Czech Republic and some other foreign countries. The first part is dedicated to rail steels with description of structure, current usage and indication of the scopes of consecutive development. In the second part, there are described the most frequent profiles, their history and the current state. This thesis includes also discussion part which compares current problems and requirements that can be significant to some possible research.

Sports car rear wing numerical optimization
Feldová, Petra ; Rudolf, Pavel (referee) ; Štefan, David (advisor)
This master’s thesis is focused on optimization of rear wing of sport car by using open-source software. The optimization of 2D profile of the rear wing is present in this thesis. Python environment was chosen for optimization and evolutionary algorithm was is used as optimization function. This algorithm is further connected to Xfoil software, which is computing aerodynamic characteristic. The ratio of the lift and drag coefficients (C_L/C_D) is chosen as parameter which considers the aerodynamic efficiency. The CFD computation of flowing around the whole car is provided in open-source software OpenFOAM. . The profile optimization results to approximately 7.9 % raise of the parameter C_L/C_D, in the same wing stability. The main benefit of this work is to use open-source software for the optimization and CFD analysis, which in future might save company’s resources by not buying expensive commercial software licenses.
