Trends in geographical information systems applications in waste management
Polášek, Marek ; Gregor, Jiří (referee) ; Pavlas, Martin (advisor)
The objective of this bachelor thesis is explanation of geographical information system issue and their application in waste management. The first part introduces the concepts of geographical information system and waste management, second part deals with usual GIS applications in waste management including the perspective trends, third part contains the overview of existing GIS software solutions and platforms including the mobile apps. Fourth part presents the specific design of GIS system for waste management.

Is old wood better than new?
Polášek, Marek
For the rescue of wooden elements and wood products are often discussions and disputes about the extent to which current technologies and materials can be brought closer to their original historical designs. At first sight, it may seems that windows made today can not have the qualities of windows that today still fulfills their function after many decades and hundreds of years. On the other hand, however, it is obvious that such this view might lead to inadequate simplification and, in our view, also sometimes leads to the requirements formulation whose technical basis may not be in line with what is already known and verified. And we would like to share this second look.

Project of production transfer
Polášek, Marek ; Prostredník, Daniel (referee) ; Fiala, Alois (advisor)
The present Master thesis deals with a transfer of the production process from Asia to Europe. The aim is to provide a life cycle of the project, its phases and the respective actions, an analysis of the risks associated with this transfer, a successful start-up of series production and the design of the internal audit as a standard of control for setting a stable and quality manufacture of the product in the Brno production plant.

Evaluation of the fillet weld geometry on process parameters for laser welding of stainless steel
Polášek, Marek ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The present thesis deals with welding of samples to examine the resulting geometry of the weld in dependence on process parameters of the laser. Welding was carried out without additional material using a fibre laser. The material used was stainless steel ČSN EN 17 241. The values of regression coefficients of the resulting graphs show that the changes in the weld geometry - width and depth - vary quite linearly depending on the welding performance. Especially the weld depth is a common requirement in technical practice; the measured results of the experiment can be used to set the process parameters to achieve the desired depth of weld. Some welds exhibit weld defects such as porosity caused by formation of the keyhole due to a large dynamics of the process. The technical-economic evaluation offers a price estimate for one meter of weld for each welding speed used.
