Knowledge Discovery in Spatio-Temporal Data
Pešek, Martin ; Bartík, Vladimír (referee) ; Zendulka, Jaroslav (advisor)
This thesis deals with knowledge discovery in spatio-temporal data, which is currently a rapidly evolving area of research in information technology. First, it describes the general principles of knowledge discovery, then, after a brief introduction to mining in the temporal and spatial data, it focuses on the overview and description of existing methods for mining in spatio-temporal data. It focuses, in particular, on moving objects data in the form of trajectories with an emphasis on the methods for trajectory outlier detection. The next part of the thesis deals with the process of implementation of the trajectory outlier detection algorithm called TOP-EYE. In order to testing, validation and possibility of using this algorithm is designed and implemented an application for trajectory outlier detection. The algorithm is experimentally evaluated on two different data sets.

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.

Activity Recognition from Moving Object Trajectories
Schwarz, Ivan ; Zendulka, Jaroslav (referee) ; Pešek, Martin (advisor)
The aim of this thesis is a development of a system for trajectory-based periodic pattern recognition and following GPS trajectory classification. This system is designed according to a performed analysis of techniques of data mining in moving object data and furthermore, on recent research on a subject of a trajectory-based activity recognition. This system is implemented in C++ programming language and experiments addresing its effectiveness are performed.

Moving Objects Indexing
Vetešník, Jiří ; Chmelař, Petr (referee) ; Zendulka, Jaroslav (advisor)
This work is aimed for proposing acceptable indexing of moving objects. With the enlargement of mobile computing it is needed to manage large sets of spatiotemporal data. We introduce the problem of spatiotemporal data and basic general approaches of indexing these data. Further, we show support of spatial data in Oracle. The movement is typically represented as trajectory in two dimensional space with temporal component in third dimension. The thesis contains experiments performed in database Oracle on artificially generate data.

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.

Damage correspondence of car hit by the fragments of roofing
Prnka, Jiří ; Sedlák, Robert
The article deals with the traffic accident with supposed contact of a car with fragments of roofing, which were lost from an oncoming truck, and caused subsequent running off a car into a ditch. Based on correspondence damage, mechanism of damage and movement of fragments of roofing it was researched if the question could arise as mentioned accident plot, as it was described by the participant.

Advanced trajectory management techniques for model station in the OPNET Modeler environmen
Ludvíček, Pavel ; Mácha, Tomáš (referee) ; Vajsar, Pavel (advisor)
The aim of this work is to study and theoretically process existing movement options of station in OPNET Modeler environment. These options are described in first part. Furthermore to design and implement function to display path obtained from real-world conditions and done to station following this route during simulation. Coordinates used to move station are obtained by GPX format, which is used to store clearly the GPS coordinates. Second part is devoted to describing creation of this function, first using PHP script, then direct implementation into OPNET Modeler environment using C++.

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.

Trajectory planning for vehicle with four steering and driven wheels
Trávníček, Tomáš ; Vejlupek, Josef (referee) ; Grepl, Robert (advisor)
This thesis deals with trajectory planning and driving for two-wheel steering (2WS) and four-wheel steering (4WS) vehicle in environment with static obstacles. Algorithms, mentioned in the search, are used for planning the path for vehicles with front wheel steering. The kinematic model is ana-lyzed and simplified. The problem of trajectory planning is solved in Matlab using trajectory dis-cretization and searching within the state space. The implemented algorithm deals with obstacle collisions as long as the map is obtained, therefore the planning does not take so much computa-tional time. Finally, the algorithm is tested on a two-wheel minibike. The solution is applicable for variety of vehicles with additional movement possibilities, even when adapted it can deal with planning in the three dimensional workspace. The results of this thesis are applicable for planning for 2WS and 4WS vehicles.

Asymptotic stability of systems of linear ordinary differential equations in engineering
Mašek, Jakub ; Opluštil, Zdeněk (referee) ; Tomášek, Petr (advisor)
This bachelors thesis is dealing with stability of system of linear ordinary dierential equations and specially lyapunov stability and asymtotic stability.The are established necessary concepts from the theory of stability and form systems of dierential equations at rst. Furthermore there are listed basic methods for determining the stability of linear dierential equations with constant coecients and they are compared. The next part of thesis is dedicated to trajectory in plane with focus on isolated singular points. At the end are two technical applications and they are linked sections and oscillators.
