Procedural modeling and realism in computer graphics
Beneš, Jan ; Křivánek, Jaroslav (advisor)
One of the long-standing goals of computer graphics is to generate realistic imagery. This realism is predicated, among other things, on having access to high- quality content to display, and being able to verify its realism. Unfortunately, realism and especially realism in procedural modeling are under-represented in current literature. Consequently, we address these two topics by investigating the definitions of general realism in computer graphics and by providing a basic framework for thinking and talking about realism in procedural modeling. In or- der to provide this framework with initial tangible data, we present a user study of the realism of procedural buildings. We find that realism of this specific class of procedural models is carried on different scales and conclude that authors of procedural rules for buildings need to beware of not only the fine details, but also the overall shape of the generated models. Finally, we present a method for growing procedural road networks in and close to cities. We use a traffic simula- tion and adapt existing research to grow cities over time. The cities are formed by letting several meaningfully positioned smaller settlements' minor roads grow in step with additional major roads. As a result, we are able to generate cities with rich, complex and realistic...
Verification of the urban design of Mendlovo náměstí from the point of traffic
Zelinka, Petr ; Všetečka, Martin (referee) ; Apeltauer, Jiří (advisor)
The diploma thesis deals with the modeling of traffic in the Mendel Square according to the documents of the Office of the Brno Architect. The modeling process takes place in software Aimsun. The result of this work is to compare the data with the provided results according to the standard, to determine the resulting output values from the software and to identify the problem areas affecting individual transport and urban public transport.

Analysis of electrical and thermal effects during electroporation
Novotná, Veronika ; Richter, Aleš (referee) ; Hána,, Karel (referee) ; Červinka, Dalibor (advisor)
This dissertation thesis describes a phenomenon called electroporation. It is about its theoretical aspects as well as about modeling of processes in the tissue during electroporation. Further, it describes the technical design of two developed unique experimental generators of DC and AC pulses for electroporation purposes. It also includes a description of experiments which were done using discussed generators.
Methods in research of insects mobility
Jor, Tomáš ; Hadrava, Jiří (advisor) ; Lučan, Radek (referee)
Mobility is one of the basics characteristics of the insects populations. This bachelor thesis presents a compendium of methods used in research of insects mobility. In the first part are described methods of marking individuals utilized for Mark-Recapture studies aiming to study insects movements. First are presented the indirect methods of individuals tracking, further the methods of direct tracking of insects using a radio-telemetry are described. In the second part the thesis focused on modeling of insects mobility using dispersion functions with connection to metapopulation dynamics and a dispersion itself. Difusion model based methods and simpler estimates of movemensts are also presented in this part. Key words: Insects, Mobility, Mark-Recapture, Modeling
Model Train Controlled by Microcomputer
Kavánková, Iva ; Kapinus, Michal (referee) ; Zemčík, Pavel (advisor)
This bachelor thesis is about controlling model trains by camera. It deals with the analysis, design and implementation of the embedded system for modeling track management. The main part is image processing in real-time and following evaluation. Designed and realized product contains model railroad with sensor, which are controlled by open-source platform called Arduino Mega 2560 and microcomputer Rapsberry Pi 3 model B. Final system was implemented in programming language Wiring and scripting language Python.
Microscopic Simulation of the junction Malá Amerika
Horák, Michal ; Mikolášek, Igor (referee) ; Všetečka, Martin (advisor)
This bachelor thesis deals with the modeling of traffic flow in several variants of the transport network. Variants are modeled in Aimsun. Current status data was obtained by field observation. In the created models, the traffic flow of both current and future traffic intensities is simulated. Based on the outputs of the simulated operation, the variants are assessed. The proposed variants are compared and the most suitable arrangement chosen.

Čechman, David ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
The goal of the thesis is to design a modeling CNC milling machine for machining of aluminum alloys including necessary calculations and drawing documentation. In the first part there is defined a CNC milling machine and there is a search in the area of small CNC milling machines that are present on the market. In the second part is the design including the computational documentation.
Design for production of analog watch case
Vilímovský, Daniel ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The aim of this bachelor thesis is a brief introduction to the watch industry and the characteristics of Rapid Prototyping. The practical part is focused on creating models of individual watch components in 3D parametric program Autodesk Inventor and following production by various methods on 3D printer. Part of the thesis is also assembly, including the watch movement installation. The thesis is concluded with a technical-economic evaluation and comparison with currently used production methods.
Computational Model of Control and Behaviour of Self-Driven Vehicle
Kužela, Michal ; Bidlo, Michal (referee) ; Strnadel, Josef (advisor)
This thesis explains basic principles of autonomous vehicles. Based on these principles, it describes proposed simulation model of autonomous vehicle with its behavior in different outer conditions. The model is composed from sensors and vehicle itself. Sensors use an algorithm based on line intersection to detect collisions. Vehicle model is mostly described by physical formulas and custom decision algorithms. Its surrounding objects have parameters that are randomly selected for each simulation run. This thesis also explains implementation of the simulation model with its own simulation framework and an analysis tool for collected data. All of these features are implemented in JavaScript with use of Node.js and an Electron framework.
