Stress-strain analysis of the LKDS800 frame
Tománek, Jiří ; Vlk, Miloš (referee) ; Vosynek, Petr (advisor)
This diploma thesis deals with frame of the two-point crank press LKDS800, which was designed by company ŽĎAS a.s. Frame is welded construction creating the base of the press which has mass approximately 90 tonnes. Aim of this study was to perform strain-stress analysis of the frame. From obtained results perform optimization of mass this frame leading to reduce material costs and machining. In the process is frame loaded by nominal forces from the shearing process, under its own weight and inertia forces caused by moving components. As a result of the dynamic loading in welded joints there are risks of fatigue fracture. The manufacturer of the press is required to find the most loaded welded joint and it to assess the fatigue life.

Summary of FEM aplication on the basis Open Source
Tománek, Jiří ; Vosynek, Petr (referee) ; Návrat, Tomáš (advisor)
This work focuses on the summary of currently available FEM applications on the Open Source basis which are freely available on the Internet. There are three programs presented (Salome, Roshaz and Ansys) and in each of them there was an easy simple plane performed and demonstrated. In the final part, a comparison of the results and the procedures for the award plane task in the three above mentioned programs was carried out.

Production single parts "Pull rear".
Tománek, Jiří ; Císařová, Michaela (referee) ; Žák, Ladislav (advisor)
The aim of this diploma thesis is to propose a production technology of a given part based on technological and economic factors. At first it is found, if the part is producible by fineblanking. The theoretical part of the diploma thesis is concerned with the description of the conventional sheet metal cutting theory, fineblanking theory and bending theory. In the practical part of the diploma thesis, four variants of cut-in plan are dealt with including the selection of the optimal one based on technological and economic calculations. It is the production of a PULL REAR iron made of the steel sheet 11 320.21, thickness of 3 mm and a production run of 75 000 pieces per year.

Technical project for a camera system i a mountain hotel offering digital and analoque camera alternatives
Tománek, Jiří DiS ; Kos, Jiří (advisor)
The thesis deals with a project of camera observation system for a mountain hotel. The project design goes from the enclosed lay-out plans of the building and from the camera system's requirements. It describes the solutions with analog CCTV cameras and with digital IP cameras. Graphic instruments as a Digital Video Recorder for analog system and as a high-powered computer for digital system are optimised to the number of cameras and the requirements on recording. The thesis describes all hardware and software used for execution of the project including the setting and bonding. The costs of single options and time needed for execution of the project are displayed in charts. The final part of the thesis explains the designed camera systems and their costs and describes their advantages and disadvantages.

Evaluation of CPM applications - analytical portals
Tománek, Jiří ; Novotný, Ota (advisor) ; Maryška, Miloš (referee)
This thesis is concerned with evaluation CPM applications -- Analytical Portals. Based on reading up the evaluation criteria from another authors in third chapter, are chosen own criteria for evaluation of application Microsoft Office SharePoint Server 2007, where are dashboards and reports created. The thesis consists of two general sections, theoretical and practical. The theoretical section describes division of CPM applications from particular vendors of software. In second chapter are explained the most important features of CPM applications and their submission into software portfolio particular vendors, which is the first target of this thesis. In the practical section are worked up the data of fictive company named Matastav into form, which is needed for creating dashboards and reports. After that in fourth chapter, are created dashboards and reports by software MOSS 2007. Here is explanation of the creation and of course the required hardware and software installation. The software and created dashboards and reports are evaluated in fifth chapter with own chosen criteria. That is the second target of this thesis.
