History of Computer Games
Michálek, Petr ; Šoustek, Petr (referee) ; Roupec, Jan (advisor)
This thesis delves into the captivating history of video games, with a focus on the development and evolution of video game consoles. The theoretical part offers a comprehensive examination of the background and progression of video game consoles, including their inception, game development processes, hardware advancements, and the evolution of input devices. This analysis provides valuable insights into the technological and cultural milestones that have shaped the gaming industry over the years. The practical part showcases a hands-on approach to implementing the acquired knowledge by creating two games using the TIC-80 fantasy computer and Lua programming language. Drawing inspiration from retro titles, these games pay homage to the nostalgic experiences that have captivated gamers across generations. The utilization of the TIC-80 platform involved working within defined constraints to capture the essence of the old titles, while ensuring compatibility with modern hardware.

Different Boundary Conditions For LES Solver PALM 6.0 Used for ABL in Tunnel Experiment
Řezníček, Hynek ; Geletič, Jan ; Bureš, Martin ; Krč, Pavel ; Resler, Jaroslav ; Vrbová, Kateřina ; Trush, Arsenii ; Michálek, Petr ; Beneš, L. ; Sühring, M.
We tried to reproduce results measured in the wind tunnel experiment with a CFD simulation provided by numerical model PALM. A realistic buildings layout from the Prague-Dejvice quarter has been chosen as a testing domain because solid validation campaign for PALM simulation of Atmospheric Boundary Layer (ABL) over this quarter was documented in the past. The question of input data needed for such simulation and capability of the model to capture correctly the inlet profile and its turbulence structure provided by the wind-tunnel is discussed in the study The PALM dynamical core contains a solver for the Navier-Stokes equations. By default, the model uses the Large Eddy Simulation (LES) approach in which the bulk of the turbulent motions is explicitly resolved. It is well validated tool for simulations of the complex air-flow within the real urban canopy and also within its reduced scale provided by wind tunnel experiments. However the computed flow field between the testing buildings did not correspond well to the measured wind velocity in some points. Different setting of the inlet boundary condition was tested but none of them gave completely developed turbulent flow generated by vortex generators and castellated barrier wall place at the entrance of the aerodynamic section of the wind tunnel.

Study of aeroelastic interference effect among four cylinders arranged in rectangular configuration
Hračov, Stanislav ; Macháček, Michael ; Michálek, Petr
The paper describes the analysis of the destructive oscillation of a skewed steel rod with the length 21 m. The steel rod is a part of roof supporting bundle (rectangular array) of cylindrical hangers at the airport building; it is therefore exposed to frequent moderate and sometimes strong winds with the low turbulence. The vibration is analyzed from the aeroelastic perspective, i.e. the cause of the oscillation is analyzed as wake-induced vibration because the collapse was observed at the bottom downwind hanger in that array configuration. The normalized distance of hangers in horizontal and vertical directions is equal to 3.15D, and 3.8D, respectively, where D is the diameter of the hanger cross section. Experimental testing of 1:1 scaled sectional model of four-cylinder array in the wind tunnel indicates, that the cause of the high level vibration is most probably the interference galloping. The unstable behavior was detected both for the downwind hanger as a part of rectangular array and for the hanger as a part of a two hangers in a row only. The results indicate the strong influence of the top pair of the hangers on the decrease of the critical wind velocity, which is even below the value of the critical wind velocity obtained for two hangers only. The strong hysteresis effect resulting in the preservation of the high vibration amplitudes even after the decrease of wind speed far below the critical one, was observed.

Monitoring of the influence of indigenous culture of yeasts on the fermentation process of making wine
Michálek, Petr ; Molnárová,, Jana (referee) ; Vránová, Dana (advisor)
This thesis deals with the identification of wine yeasts isolated from the grape must using PCR-RFLP method. The yeasts were isolated from Pinot Noir grape variety must. Grapes were grown and produced in accordance with the requirements placed on organic and integrated farming. Samples were processed in the laboratory, where pure cultures of individual yeast were obtained. A commercial kit was used for yeast DNA isolation. Obtained DNA was used for further analysis. Using the polymerase chain reaction and the primers ITS1 and ITS4 a specific segment of 5.8S rDNA-ITS region was amplified. The PCR products were then detected by electrophoresis in an agarose gel, and after a subsequent purification, three restriction enzymes: HaeIII, HinfI and HhaI were subjected to restriction analysis. The DNA was digested to fragments specific for yeast species and they were detected by agarose electrophoresis. Similarity of these isolates was compared using BioNumerics program and the result is dendrogram of genetic similarity of isolated yeast. The basic chemical analysis of samples must was also performed.

Kotková, Jana ; Neumaierová, Inka (advisor) ; Michálek, Petr (referee)
This Master's thesis applies a method Balanced Scorecard in company Lach-Ner, s.r.o., which is part of chemical business in Czech republic. The teoretic part consists of a description of strategy creation, strategic analysis and clarification of the method Balanced Scorecard. The practical part contains strategic analysis including determination of weaknesses and strenghts, opportunities and threats. In the following chapters there is determination of strategic goals in particular perspectives of Balanced Scorecard and strategic map is created. Strategy map is the outcome of the thesis and it is a key tool for strategic management of the company.
