Path Planning of Airplane with Obstacles
Očenáš, Marek ; Zbořil, František (referee) ; Samek, Jan (advisor)
The aim of this master's thesis is the implementation of optimal trajectory planning for an airplane flying in lower altitudes, which has to avoid collision with obstacles. For the planning we assume static and fully known environment. There are described principals, optimality and complexity for some chosen methods of planning in this thesis. And based on the methods' characteristics it's chosen the best method for implementation.

Computer graphics flow visualization methods
Častulíková, Veronika ; Štefan, David (referee) ; Urban, Ondřej (advisor)
Flow visualization is one of the important topics in the scientific visualization, which is a subject of ongoing research. Data obtained by numerical simulations are further analysed to gain a better understanding of fluid flow. With the rapid development of computational simulations, demand for more advanced visualization methods has grown. Basic overview and a detailed description of the fluid flow visualization techniques is introduced in the bachelor thesis. Afterwards, the techniques are applied on data obtained by CFD simulation of a vortex rope in the draft tube swirl generator.

Platform for Measurement of Atmospheric Quantities
Hanák, Jiří ; Vlk, Jan (referee) ; Chudý, Peter (advisor)
This work is dealing with the design and implementation of an embedded system for aerology measuring. The aim of the system is to monitor atmospheric states during an ascent in the suspension under an meteorological balloon. First of all, attention is given to the Earth's atmosphere and its quantities, then an overview of existing systems for performing aerological measurements. The core of the work is focused on the choice of measurement techniques and the selection of suitable measuring elements for a given scenario. The aerological probe is using atmospheric sensors HIH-8131-021-001, MS5611-01BA03 and PT1000-550 for temperature sensing, while GNSS data is received using the MAX-M8Q-0 module and the measured data is stored on a microSD card and transmitted in parallel using the MTX2-434.650-10 radio module. The system is controlled by STM32L1 from STMicroelectronics programmed in C using HAL abstraction layer.

Simulation of a Golf Ball Trajectory from Video
Hlobil, Marek ; Ševcovic, Jiří (referee) ; Chmelař, Petr (advisor)
This work deals with the golf ball flight simulation based on video recordings. The way how to determine the trajectory of a golf ball using several initial points is described here. For the ball recognition there are used computer vision techniques, particulary pattern recognition. The work covers physics of the golf ball, it deals with physical influences that occurs during the ball flight and it tries to describe the trajectory approximation.

Knowledge Discovery in Object Relational Databases
Chytka, Karel ; Vrážel, Dušan (referee) ; Chmelař, Petr (advisor)
The goal of this master's thesis is to acquaint with a problem of a knowledge discovery and objectrelational data classification. It summarizes problems which are connected with mining spatiotemporal data. There is described data mining kernel algorithm SVM. The second part solves classification method implementation. This method solves data mining in a Caretaker trajectory database. This thesis contains application's implementation for spatio-temporal data preprocessing, their organization in database and presentation too.

Simulator of mobile robots in Matlab/Simulink
Havlát, Petr ; Honzík, Petr (referee) ; Hrabec, Jakub (advisor)
The main goal is the programming scene MATLAB/Simulink creation of graphic user interface (GUI), which allows the simulation of mobile robots movement. The work covers two types of these robots – first one is the robot with differentially controlled truck and second one auto robot (car-like robot). As a part of this draft GUI, there are also possibilities of showing all trajectory or only actual position, selection of step after which the robot can delineate and possibility of layout between the positions by using the button back and forwards.

Periodic solutions to differential equations in modelling of motion of mechanical systems
Koukalová, Kateřina ; Nechvátal, Luděk (referee) ; Šremr, Jiří (advisor)
This thesis focuses on modelling the motion of mechanical systems using differential equations. The mechanical system is represented by a charged pendulum attracted by two charged particles. The thesis deals with the analysis of the differential equation describing the motion of the pendulum, in particular the singular points of the studied equation. We determine their number, type and stability. Based on the values of the parameters of the mechanical system, the singular points differ, phase portraits are drawn for each case.

On the kinematics of wheeled mobile robots
Zoufalý, Stanislav ; Hrabec, Jakub (referee) ; Burian, František (advisor)
The bachelor thesis deals with the description of the concepts of nonholonomic mobile robots. Its aim is to get acquainted with the basic variants of structures, to build a mathematical model, to derive dynamic properties and to design a functional algorithm of a control system. The work describes the selection of suitable models, the implementation of two basic types of chassis and the selection of a suitable simulator for the implementation of models. These are types with Differential and Ackerman chassis. The thesis next describes the design of suitable control so as to meet the requirement of tracking the desired trajectory. Control algorithms and mathematical models were implemented in the MATLAB-Simulink software environment with the possibility of real 3D simulation in the Webots simulator.
