The Use of Linear Programming for Optimization of Transport Problem
Macharová, Aneta ; Dostál, Petr (referee) ; Doskočil, Radek (advisor)
This bachelor’s thesis focuses on methods and processes that take place in the company when optimizing transportation cost factor. The first part deals with the theoretical introduction into linear programming methods and distribution tasks including a description of economic and mathematical models. In this part I will also explain the add-on „The SOLVER" which is used for optimal calculations. The practical part uses the described methods with real data from the company "Agromex"; the company will be introduced in this part. The problem that will be solved will also be listed. I will present the models I have created, proposals for solutions and I will interpret the results using the calculation of the add-on „The SOLVER".
Computational Model and Analysis of Adaptive Traffic Lights
Terbr, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This thesis deals with the topic of adaptive intersections and the study of their influence on the flow of traffic and others. The work contains an analysis of currently used traffic detectors, an analysis of the main problems of classic intersections and the possibilities of their solution, followed by the design of the model, a description of the implementation and testing of the created model. The resulting model is created in the UPPAAL SMC software and is a system of timed automata communicating with each other. Testing is performed by comparing the results of tests of classical traffic lights with the results of adaptive traffic lights.
ESP/ESC Impact to Behavior of Vehicle
Weigel, Filip ; Mrázek, Vojtěch (referee) ; Strnadel, Josef (advisor)
This bachelor thesis focuses on active safety - ESP. System ESP greatly improves stability of vehicle while turning. The thesis analyses modelling, brake functionality, subordinate systems of ESP - ABS and ASR, physical forces and phenomenons, model example, analysis of problem, design of model, implementation of model and experiments evaluation of implemented model in UPPAAL enviroment. The goal of the thesis is to prove that ESP system helps to stabilize vehicle while turning by simulation of vehicle model. Results are presented in well-aranged graphs side-by-side. It is possible to analyze the behaviour of vehicle while turning with ESP or without ESP.
Mathematical Model of Quadcopter
Gajdošík, Martin ; Veigend, Petr (referee) ; Rozman, Jaroslav (advisor)
The aim of the bachelor thesis is to create a mathematical model of a quadcopter and its subsequent simulation in MATLAB and Simulink environment. It will also deal with a design and implementation of an autonomous control system with which we will perform flight tests in two flight configurations. These configurations will be with one or two engines in front of vehicle. We will also look at the computational complexity of this model and the possibilities of further expansion.
ABS Impact to Behavior of Vehicle
Zich, Jakub ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The bachelor thesis discusses the Anti-lock braking system and its impact on braking distance of a vehicle. The thesis contains research of this problem, a summary of suitable modeling tools, solution draft, its implementation in the UPPAAL modeling tool and tests performed with the model. The tests examine the course of progression of basic quantities associated with braking (velocity, braking distance, slip, angular velocity, friction coefficient) in simulations of emergency braking with and without the use of ABS, and compare the results. They also verify probability of the vehicle stopping in different circumstances on given distance. Lastly, the model can simulate brake or sensor defect, and results of those simulations can be compared to simulations without defect.
Design and Implementation of Effect Model in Simulation System OneSAF Testbed Baseline
Hubeňák, Marian ; Kunovský, Jiří (referee) ; Rozman, Jaroslav (advisor)
This project deals with the modelling and the simulation, its basic characteristics as well as its respective branches. The majority of the project is aimed at modelling and simulation in military environment with a description of the asset in this area while considering different uses of these simulations. I also introduce the development of modelling and simulation in the army of Czech Republic. The project also deals with the constructive simulation and tries to bring out the OneSAF Testbed Baseline simulation system. At last, I propose some concepts of models for this particular simulation system - the model of psychological effects and the model of generating the rubble during the operations of the artillery.
Modelling of PowerPC Processor
Blaha, Hynek ; Dolíhal, Luděk (referee) ; Masařík, Karel (advisor)
Processor architectures are becoming increasingly complex, so great emphasis is put on the automation of their desings. This bachelor thesis describes the design of the PowerPC processor architecture in Codal language. The model is created according to avaliable documentation. The functionality and efficiency of the model was verified by tests provided by research group Lissom and compared to current competitor.
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.
