Use of Pareto analysis for production data processing
Ručka, Petr ; Ošmera, Pavel (referee) ; Pásek, Jan (advisor)
This bachelor's thesis deals with the realization of Pareto analysis in the system COMES Modeller. The first part describes the Pareto analysis and Lorenz curve, together with instructions, how to properly apply the Pareto analysis on data obtained from the manufacturing process. Furthermore, they are also mentioned other methods, which have applications in industry. Pareto analysis is then compared with them. The second part of this thesis focused on the system COMES and design implementation and realization Pareto chart in this system.

Automatic process control of aftercooling in brickkiln
Cacek, Jan ; Ošmera, Pavel (referee) ; Němec, Zdeněk (advisor)
The thesis deals with the design of the multivariable automatic control system of aftercooling process in the brick industry tunnel kiln. Theoretical part submits the facilities of controlled systems identification and the design methods of uni and multi variable systems. In the practical section is cleared up the principal of the aftercooling process and its identification based on the measured data. The output of the thesis is the design and the analysis of multivariable system with the conservation of the control circuit autonomy.

Cryptography and implementation in Notes and Domino
Klusoňová, Eva ; Karakhalil, Mourad (referee) ; Ošmera, Pavel (advisor)
This bachelor's thesis deals with description of cryptography and Public Key Infrastructure in Lotus Notes/Domino. The goal of this thesis is to give a brief overview of cryptographic techniques including their implementation in Lotus Notes/Domino and to propose an appropriate examples for demonstration and education in cryptographic techniques. In order to demonstrate selected algorithms an open-source e-learning software CrypTool is used.

Aerofoil Aerodynamic Features Optimization
Müller, Jan ; Rozehnal,, Dalibor (referee) ; Popela, Robert (referee) ; Zelinka, Ivan (referee) ; Ošmera, Pavel (advisor)
The content of the presented thesis is advanced optimization of the aerofoil wing of a general aircraft. Advanced metaheuristic optimization techniques based on evolutionary calculations and swarm algorithms are used for optimization. These algorithms are characterized by robustness of optimization and engineered degree of convergence and optimality of the solution. Within the solution, fundamental modifications of the original aerofoil optimizations were designed and implemented. A new variant of aerofoil evolutionary algorithms (aEA) was created from the original evolutionary algorithm (EA), followed by a new variant of aerofoil particle swarm optimization (aPSO) developed from the original particle swarm optimization (PSO). Then the hybridization of the mentioned methods was created in a parallel variant. The Bezier-PARSEC 3434 parameterization model that generates the aerofoil shape was used for the optimization process. A parametric model based on B-Spline was used to optimize the original aerofoil. Fluid dynamics simulation for the calculation of basic aerodynamic features (lift, drag, moment) was realized by Xfoil software. The results are then verified using fluid dynamics simulation (CFD ANSYS Fluent). From the point of view of optimization tasks developed by optimization and implementation, it is clear that this is a complex interdisciplinary task, the results of which are presented in this thesis.
