The Game in the Filosofical and Pedagogical Reflection and Use of Simulation Games in Social Sciences Teaching
Němcová, Lenka ; Zicha, Zbyněk (advisor) ; Pelcová, Naděžda (referee)
This diploma thesis focuses on the issue of human game, from several points of view, namely philosophical, pedagogical and didactic. The work is structured into three parts. The theoretical part deals with the philosophical considerations concerning the game phenomenon, where the game is based mainly on the ontological principle and the game theory, which is analyzed by selected authors. The second part then deals with the game used in the pedagogical processes, or the game as a teaching method in the field of social science and its importance in teaching at primary and secondary schools. The practical part is focused on simulation games implementation within the social science - education.
Simulations of open-ended evolution
Prax, Sebastian ; Toman, Jan (advisor) ; Tureček, Petr (referee)
Evolutionary algorithms are used to solve a number of optimization problems in the computer science. At the same time, they are fundamental pillar for creating evolutionary simulations and testing scientific hypotheses in a various areas of theoretical biology. In the first half of my work, I characterize the concept of "open-ended evolution", focus on its connection with the technical side of simulations and introduce readers to the problematics of system simulation. Further on, I deal with the phenomenon of increasing complexity and the idea of "evolutionary progress". All these topics are confronted with various perspectives of researchers in the field of evolutionary biology. In the second half, I summarize the benefits of existing projects for evolutionary biology and applied informatics, as well as the ways in which the simulations of open-ended evolution can be approached. Basically, these projects can be divided into two categories. They are either projects in which individuals develop towards a predefined goal, which is conditioned by a fitness function, or projects of researchers who seek to achieve an open-ended evolution by employing biologically realistic design of the genetic code and environment in conjunction with the absence of a particular attractor in the evolution of virtual...
Modelica in physiological modelling. Models with spatially distributed parameters, Authorin educational simulators.
Šilar, Jan ; Kofránek, Jiří (advisor) ; Maršálek, Petr (referee) ; Roubík, Karel (referee)
Mathematical models in physiology are useful to formulate and verify hypotheses, to make predictions, to estimate hidden parameters and in education. This thesis deals with modelling in physiology using the ​Modelica language. New methods for model implementation and simulator production were developed. Modelica is an ​open standard equation-based object-oriented language for modelling complex systems. It is highly convenient in physiology modelling due to its ability to describe extensive models in a lucid hierarchical way. The models are described by algebraic, ordinary differential and discrete equations. Partial differential equations are not supported by the Modelica standard yet. The thesis focuses on two main topics: 1) modelling of systems described by partial differential equations in Modelica 2) production of web-based e-learning simulators driven by models implemented in Modelica. A Modelica language extension called PDEModelica1 for 1-dimensional partial differential equations was designed (based on a previous extension). The OpenModelica modelling tool was extended to support PDEModelica1 using the method of lines. A model of countercurrent heat exchange between the artery and vein in a leg of a bird standing in water was implemented using PDEModelica1 to prove its usability. The...
Study of probe diagnostics of tokamak edge plasma via computer simulation
Podolník, Aleš ; Pánek, Radomír (advisor) ; Cavalier, Jordan (referee) ; Roučka, Štěpán (referee)
The aim of the thesis is to examine plasma-wall interaction using computer modeling. Tokamak- relevant plasma conditions are simulated using the particle-in-cell model family SPICE working in three or two dimensions. SPICE model was upgraded with a parallel Poisson equation solver and a heat equation solver module. Plasma simulation aimed at synthetic Langmuir probe measurements were performed. First set considered a flush-mounted probe and the effect of variable magnetic field angle was studied with aim to compare existing probe data evaluation techniques and assess their operational space, in which the plasma parameters estimation via fit to the current-voltage characteristic is accurate. Second simulation set studied a protruding probe pin. Effective collecting area of such probe was investigated with intentions of density measurement collection. This area was found to be influenced by a combination of two factors. First, the density dampening inside the magnetic pre-sheath of the probe head, and the second, the extension of the area caused by Larmor rotation. A comparison with experimental results obtained at COMPASS tokamak was was performed, confirming these results. Keywords Langmuir probe, simulation, particle-in-cell, tokamak, Poisson equation, COMPASS 1
Modelling of mmWave Propagation Channel for Off-body Communication Scenarios
Zeman, Kryštof ; Vozňák, Miroslav (referee) ; Gaydamaka, Yulia (referee) ; Hošek, Jiří (advisor)
Předkládaná disertační práce je zaměřena na \uv{Modelování propagačního kanálu pro off-body komunikaci v oblasti milimetrových vln}. Navzdory pokrokům v rámci bezdrátových sítí v přímé blízkosti člověka stále systémy 5. generace postrádají dostatečnou šířku pásma a dostatečně nízkou odezvu. To je způsobeno neefektivním využíváním rádiového spektra. Tento nedostatek je potřeba co nejdříve odstranit a právě z tohoto důvodu je hlavním cílem této práce navrhnout vylepšený model rádiového kanálů pro off-body komunikaci. Úkolem tohoto modelu je umožnit uživatelům efektivněji a přesněji simulovat propagaci signálu v rámci daného prostředí. Navržený model je dále optimalizován a ověřen vůči nejnovějším měřením, získaným z literatury. Nakonec je tento model implementován do simulačního nástroje NS-3, pomocí kterého je následně využit k simulaci množství scénářů. Hlavním výstupem této práce je ověřený model přenosového kanálu pro off-body komunikaci v rámci milimetrových vln, společně s jeho implementací do simulačního nástroje NS-3, díky čemuž je dostupný pro širokou veřejnost.

Vysloužil, Robin ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
This thesis compares different freely available simulation tools. The aim of the thesis is to document and compare tools implemented in Modelica, MATLAB and Python. Various simulation models are created for each language. The models were simulated and the results from simulation runs were evaluated.
Modular Simulator of Microcontroller
Vosyka, Pavel ; Janoušek, Vladimír (referee) ; Peringer, Petr (advisor)
In this thesis, free access existing microcontroller simulators were found. A microcontroller simulator with a graphical user interface was developed. The simulator is able to change between different microcontrollers. Surroundings of microcontroller's simulation are made of predefined electrical circuits, which can be arbitrarily connected with the microcontroller. The simulator was implemented and tested. Also, ATmega328p microcontroller was implemented in the simulator.

Hudec, Jan ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
Output of this bachelor’s thesis is an attack generator aimed on IEC 61850 protocol using the libpcap library. Part of the output is also a simulation of devices which are normally present in SCADA systems. Theoretic part aims to explain protocols DNP3, IEC 60870 and IEC 61850 more in-depth and further focus is on the attacks. Practical part contains attack implementation that aim on communication between SCADA units, more precisely on GOOSE and Sampled Values frames. Simulated devices generate this communication using the libiec61850 library. Attacks are aimed on that communication.
