Doctoral thesis is focused on a design of a new original image transition edge physical modeling method for exact object shape position determination. Automatic Optical Inspection systems for the high accuracy optical measurements is main application area for designed method. The new method design is based on precise physical analysis of a defined imaging system. Object side telecentric lens, telecentric backlight source and CCD video camera are main parts of the analyzed imaging system. New image transition edge physical model and method for accurate shape position detection within the model are derived by geometrical and Fourier optics imaging system analysis. Possible influences of the model parameters changes to the accuracy of shape position detection are studied precisely. A new modeling function suitable for implementation in a new optimal approximation method is derived from the physical transition edge model. The modeling function optimal approximation method is implemented in to a Tester2D measuring system and verified by length etalon measurements. The Tester2D measuring system was successfully accredited for dimensions measurement in range with accuracy up to . Documentation of results of the accreditation process with the record of obtained results from measurement system in scope of preformed interlaboratory comparison tests are appended to the doctoral thesis.

Práce se zabývá empirickým ověřením platnosti efektu biče u reálného dodavatelského řetězce. Zároveň na reálných datech ukazuje rozdíl mezi optimalizací zásob každého dílčího článku řetězce a optimalizací zásob podél celého řetězce. Součástí práce je vytvořená učební pomůcka pro ukázku optimalizace zásob (model EOQ) a Pivní hra pro demonstraci platnosti efektu biče.

This thesis deals with the solution of numerical modeling. Consequently problems associated with the flow of the water over spillway of the specific water structure. In this case numerical modeling means modeling of fluid movement, which is described by mathematical means. Especially nowadays, when a lot of spillways need to be recalculated, whether it meets the capacity demands, or there is no need to tackle reconstruction. With today's software capabilities there is a wide range of commercial and freeware resources. The numerical model, compared to physical model is less accurate which is, on the otherhand, physical model is usually financially and time-consuming. The following work simulates the behavior of water on the edge of the spillway, in the trough and then behind the trough. The result is a comparison of the water depth in the trough calculated by the numerical and the physical model.

The thesis is concerned on numerical modeling of a scheduled spillway on water structure Letovice. The goal of the thesis is to verify hydraulic calculation using numerical modeling and to verify the capacity of the spillway. The spacial model was created in SketchUp program and the numerical modeling was implemented in Flow-3D program. The reason to recalculate the spillway is its reconstruction and extension in order to make high a capacity of it in the final project of Letovice water structure whole reconstruction.

This study investigates Game theory including economic theories related to agricultural production. Model creation simulating economical system is built upon theoretic starting points. Commodity production is simulated using game theory with searching for Nash equilibria. Commodity demand function is grounded on concept of Cournot game. System includes land trading based on sealed-bid auctions with second-price. This model is using external Gambit software which is freeware library for game theory computations. Model evaluation is located in Experiments section where model structure and truthfulness is tested.

Master's thesis concerns itself with a design of a brand new business simulation game. The first part defines business simulation games as a specific form of educational activity and describes their individual components. The second part is fully dedicated to design. It specified goals and requirements for the proposed software application and economic model of the game and describes ways to implement them. The design focuses on technical aspects of the game, on defining specific algorithms for the model to use and on implications of relationships among variables in the proposed model.
