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.
Design of a CNC modeling milling machine for machining aluminum alloys
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.
x86 Assembler Simulator for Education
Heštera, Andrej ; Semerád, Lukáš (referee) ; Orság, Filip (advisor)
Point of this thesis is gain knowledge base of x86 Instruction Set Architecture and x86 assembly language through analysis. Based on this knowledge, design and implement simulation environment in object oriented programming language Java SE8. This environment will give user option to create code based on conventions and syntax of Netwide Assembler and simulate created code on virtual representation - simulation model, which will imitate behavior of processor implementing instruction set architecture x86. The result of using this environment should be new knowledge for user about basic function of machine code execution and how this execution alters state of processor, without the need to specially compile created code for use in Debugger and having physical system implementing architecture x86.
Optimization of ventilation in the production hall
Myjavec, Patrik ; Uher, Pavel (referee) ; Blasinski, Petr (advisor)
Diploma thesis is divided into two parts. The theoretical part deals with natural ventilation and the practical part focuses on the optimization of the ventilation in the original hall using CFD simulation. One of the solutions is proposed in the design part of the diploma thesis.
Hydroscopic Behaviours of Ammonium Sulfate/Organic Mixtures Including Dicarboxylic Acid and Oligomer.
Bouzidi, Hichem ; Zuend, A. ; Ondráček, Jakub ; Schwarz, Jaroslav ; Ždímal, Vladimír
Here, the hygroscopic behavior of submicron particles composed of ammonium sulfate (AS), dicarboxylic acids (including oxalic acid (OA), malonic acid (MA)), and oligomer Poly(ethylene glycol) (PEG-300 (-CH2OCH2-)n) is investigated with a Hygroscopicity Tandem Differential Mobility Analyzer (HTDMA), under relative humidity (RH) below 100%. The aerosol systems were varied in their complexity and ranged from single-component to more complex systems (2, 3 and 4 components). The experimental data are compared with predictions from Zdanovskii-Stokes-Robinson (ZSR) mixing rule (Stokes and Robinson, 1966) and the thermodynamic model Aerosol Inorganic-Organic Mixtures Functional groups Activity Coefficients (AIOMFAC) (Zuend et al., 2011).

Pedestrian modelling during sport events outside of the stadium
Zelinka, Petr ; Plášek, Josef (referee) ; Apeltauer, Tomáš (advisor)
The bachelor thesis deals with modeling the movement of people around the new Brno sports stadium after the end of the match. The process of modeling the movement of people was done in Pathfinder. The output is an analysis of the current risks associated with the quality of the transport, the determination of the time to exits, the comparison between different variants and attendance.
