This diploma thesis deals with the actual problems of sports car. This project solves the basic question of the future ecological cars drive and deals with problems related to ergonomics adherent to this type of car. The work includes a detailed retrieval study of the issue followed by the procedure of designing the car. The conclusion of the thesis deals with the detailed description and an analysis of the concept from several points of view. This thesis is also supplemented by preview of po-sters and multimedia presentation for 3D virtual reality.

Optimalizace toku v síti je klasickou aplikací matematického programování. Tyto modely mají, mimo jiné, široké uplatnění také v logistice, kde se tak snažíme docílit optimálního rozdělení dopravy, např. vzhledem k maximalizaci zisku, či minimalizaci nákladů. Toto pojetí ovšem často problém idealizuje, poněvadž předpokládá existenci jediného rozhodovatele. Takový přístup je možný ve striktně organizovaných sítích jako např. v logistických sítích přepravních společností, železničních sítích či armádním zásobování. Úloha ''Traffic Assignment Problem'' (TAP) se zaměřuje na dopady teorie her na optimalizaci toku, tj. zkoumá vliv více rozhodovatelů na celkové využití sítě. V práci se zaobíráme úlohou TAP s působením náhodných vlivů, k čemuž využíváme metod stochastické a vícestupňové optimalizace. Dále zkoumáme možnosti zlepšení stávajícího využití sítě za rozhodnutí autoritativního rozhodovatele, kterému je umožněn zásah do samotné struktury sítě, k čemuž využíváme víceúrovňové programování.

This diploma thesis deals with designing a drivetrain for a coal belt conveyor. Thesis contains necessary calculations according to norms needed for determining suitable components of a belt conveyor. The goal of this diploma thesis was to design a drivetrain for a belt conveyor, all its components including a frame of the drivetrain and to create drawing documentation.

This thesis deals with the use of the tractor in agricultural transport. The first part describes the current status in construction of tractor engines, transmissions and chassis that are used in tractors suitable for transport. The theoretical section includes an overview of the legislative requirements that must be followed for the tractor kits in transport on the road. The main objective of this thesis was to evaluate a measuring of fuel consumption and efficiency of the tractor JCB Fastrac 185-65 with two flatbed trailers. For this purpose was created the methodics off terrain measurement, which were carried out for different operation modes of the engine. The results were tabular and graphical processing including determining the accuracy of the method by calculating the relative error of measurement. For comparison a theoretical calculation of the consumed fuel was made. The aim of the measurements was to demonstrate fuel-saving during operation engine in the economic field and get an overview about fuel consumption and efficiency kits.

The aim of this thesis is to design a conveyor belt readjustable to transport brown coal according to specific parameters. The introduction is focused on describing and dividing conveyor belts and characterizing their individual parts. The main part of the thesis is a description of selected components and design solutions, a functional computation carried out in accordance with the standard ČSN ISO 5048 and further an analysis of transported material's properties. The drafting documentation is attached to the thesis.

This master‘s thesis describes the design and implementation of the system for detection and recognition of speed limit road signs. It focuses on the recognition of the red circular speed limit sign from the image data using the computer vision methods. Several methods were programmed and tested as a part of this thesis. In the final solution, the segmentation based on YCbCr color model is used. Detection of the circular sign and final classification is performed by template matching method. Algorithm for the tracking of the detected signs between frames of the video is used for better performance in real-time recognition. Application is developed using MATLAB and Simulink. The result is a simple driver assistance system prototype, which can be implemented in any computer with camera. The correct function of the algorithm was confirmed during a testing in a traffic.

Tato diplomová práce prezentuje problematiku dopravního toku a jeho modelování. Zabývá se především několika LWR modely, které následně rozebírá a hledá řešení pro počáteční úlohy. Ukazuje se, že ne pro všechny počáteční úlohy lze řešení definovat na celém prostoru, ale jen v určitém okolí počáteční křivky. Proto je dále odvozena metoda výpočtu velikosti tohoto okolí a to nejen zcela obecně, ale i pro dané modely. Teoretický rozbor LWR modelů a řešení počátečních úloh jsou demonstrovány několika příklady, které zřetelně ukazují, jak se dopravní tok simulovaný danými modely chová.

This diploma thesis deals with a comprehensive analysis of the photographic documentation of vehicle damage in traffic accidents. A systematic overview of the current documentation and included inspection is carried out in the analysis. Police records are compared with records made during the crash tests. Further, the documentation in this thesis is divided into two groups of conflicts. The representative of the accidents are described in detail and then evaluated. Similarly, this procedure is practiced on other car accident that reflect the mutual deformation. The result of this thesis is to determine the optimal location of the lens for the acquisition of documentation and establishing a baseline number of photos to document damage to the vehicle after the traffic accident.

Diploma thesis Selected measurements of the motion of bicycles – braking and ridein the curve analyses problematic manoeuvres of bicycle riders according to the most typical accidents including bikes. There will be given statistics of bikers´ participation on accident amount that happened within last few years. The measurements of bicycles moving around bands of specific radiuses as a situation of most bicycle accidents will be described in the next part of this thesis. There will be also specified the values of average bicycle speeds when driving in curves with various radiuses according to types of bicycles, sex and experiences of the riders and will be an output of this thesis. Further on there will be measurements of braking in the direct line on various surfaces with different types of bikes and different brakes used.

This work deals with the analysis of traffic car-accidents in the Czech Republic, Sweden and Denmark. Excepting the analysis, it contains basic information and evaluation. Then in the final part is also given a proposal of measures to reduce car-accidents in the Czech Republic.
