Chren, Tibor ; Hlinka, Jiří (referee) ; Píštěk, Antonín (advisor)
This diploma thesis deals with design of retractable landing gear for Rapid 600 aircraft. The main purpose of this thesis is to analyze different retraction options for front and main landing gear and resulting selection of suitable variants. The thesis is consequently concerned with design of selected options including proposal of automatic landing gear control system and specifying the features and characteristics of this system. In the thesis there is also included the analysis of critical flight conditions which could be detected by this system.

Functional Hazard Assessment (FHA) of 4-seat aircraft
Jakl, Jan ; Weisman, Andrej (referee) ; Hlinka, Jiří (advisor)
At the beginning this master's thesis includes of a comprehensive review of aircraft accidents in this category, 2-6-digit aircraft for passenger transport. Since this work focused on autopilot, so naturally there is a basic overview of most common autopilots, which can be found in these aircraft now, but in the future. Functional hazard analysis (FHA) for the 4-seater plane for passenger services primarily investigates cases of catastrophic malfunction, which in most cases accompanied by the likelihood taken from different databases. The airplane, which is created for this analysis will preferably equipped with instruments for IFR flights. There is also a brief overview of the regulations necessary for the installation of these systems in the airplane. At the end of this work is to design the dashboard, a design layout of equipment for future aircraft, with an emphasis on maximum transparency.

Web-based application for Czech language e-learning
Lam Van, Duyet ; Vodňanský, Daniel (advisor) ; Zumr, Jiří (referee)
Lack of knowledge of the Czech language means a serious problem for foreigners living in the Czech Republic. Czech language should help them in communication, business, studying, but for some people it is also the necessary condition for obtaining a permanent residence. The aim of this bachelor thesis is to design and implement a web application that should serve as a source of learning the Czech language for foreigners. To achieve this goal, the thesis first deals with the analysis of the existing solutions for Czech language e-learning. A design of a web application, user interface and the structure of the database model is suggested based on the finishing analysis. After designing the web application, its development follows, in which the client/server architecture and selected web technologies including Laravel Framework, jQuery and MySQL database system are used. The output of this work is a detailed web-based application that provides an access to educational lessons, instructions and exercises for users, who need to improve in Czech language. They can test their knowledge and determine their skill level.

Rating of automotive transport system with swap bodies in the business of agricultural production.
KULÍK, Jan
This thesis deals with the evaluation of automotive transportation system with swap bodies in the business of agricultural primary production and the possibilities of its use. The Automotive transportation system can be the carrier system for several kinds of extensions because of its design. In this case, the investigated transport system in selected company uses the back of the bulk materials, tanks and bulk truck. It was the truck LIAZ 151 with hull CSAO for bulk materials, faecal tank ACF 041 and high-volume hull type for transport bulky feed. Operating and investment costs of the whole transport system, performance of each swap bodies and technical parameters were evaluated. The primary agricultural enterprise ZD Trhový Štěpánov, a. s. was also characterized. For this thesis were detected information by observing and processing time of each frame bodies. More information has been gathered from internal materials, such as a serious journal, time sheets, annual report and other enterprise data sources. In terms of economic costs, these costs have been identified - costs per km = 27,91 CZK/km, costs per tonne transported = 52,93 CZK/t and costs per tonne-km = 7,46 CZK/tkm. Total operating costs amount is 702 243.62 CZK. Another result of the investigation was determined consumption and annual use of individual bodies. For the bucket SCAO was found that the consumption is 0,69 litres per tonne transported and annual use of individual bodies is 98 days. For feacal tank ACF 041 the consumption is 29.1 liters per hectare applied of manure and Antal use of individual bodls is 98 days. The consumption of bulk superstructure is 0.93 liters to be transported tonne and was used for 34 days.

Analysis of Iron-Phosphorus Reaction Products Formation During Heat Treatment Processes
Skoumalová, Zuzana ; Jan, Vít (referee) ; Doležal, Pavel (advisor)
During high pressure pulsation tests repeated cracks of CP3. housings occur. High pressure pump CP3 is part of injection system Common Rail. Cracks can be caused by segregation of phosphorous from a washing medium on grain boundaries during subsequent heat treatment process. The present master´s thesis focuses on analysis of phosphorous compounds on specimen surface made from steel 20MnCr5, which were soaked in solutions with different concentration of phosphorous. Master’s thesis is also focused on potencial influence of phosphorous on structure and properties of this material. The first part of the thesis provides a summary of current knowledge in the studied field, experimental results can be found in the second part. The surface analysis XPS, the light microscopy, the scanning electron microscopy equipped by energy dispersive chemical analysis, the glow discharge optical emission spectroscopy, the methods of the phase analysis by means of the X-ray diffraction and impact test were used.

Fyzikální systém pro tvorbu her
Cséfalvay, Szabolcs ; Kronus, David (advisor) ; Holan, Tomáš (referee)
In the present work we ivestigate the functioning of a real-time physics engine. We also take a look at the problematics associated with the creation of such an engine, the methods that can be used to accelerate collision detection and increase the stability of the system. The current implementation of the engine can handle collisions between spheres and cylinders (without the top and the bottom), resting contact forces between objects, compound objects and springs.
