Prelouc - Hermanuv Mestec Track Speed Increase
Prikner, David ; Javořík,, Tomáš (referee) ; Dušek, Erik (advisor)
The bachelor's thesis focuses on increasing the track speed in the section of the Přelouč - Heřmanův Městec railway line. The thesis includes an analysis of the track geometry and proposes several variants to enhance the track speed by the track geometry optimisation. The individual variants are compared, and alternative methods to reduce the travel time and improve the line section attractiveness are examined.
Perception of oncoming vehicle speed
Pršeš, Faruk ; Rak, Martin (referee) ; Bilík, Martin (advisor)
The presented master thesis deals with perception of oncoming vehicle speed. The theoretical part defines basic terminology, types, and categories of motor vehicles. Furthermore, it establishes what effects sensory perception has on estimation of vehicle speed. The practical part focuses on the examination of the measured estimations of moving vehicle where the respondents are seated and the estimations of oncoming vehicle speed according to age, gender, driver’s experience, and type of vehicle. The design, preparation and realization of the experimental measurement is in this part of the thesis. Afterwards, it is followed by an evaluation of the measured data, which gives us a better idea of how precise the witness estimations are at the traffic accident.
Perception of vehicle speed
Hlavinková, Petra ; Dadák, Leo (referee) ; Bilík, Martin (advisor)
The presented master thesis deals with the perception of the speed vehicle crew (not the drivers) in traffic in terms of different aspects, that influencing the feeling while driving in the vehicle. This is primarily about the approximation of factors that may have an impact on the speed. The aim of the thesis is to propose an appropriate methodology of measurement and subsequent evaluation of acquired date, which leads to an improvement in the idea of whether witnesses of traffic accidents are indicative of the speed of the vehicles, at reasonable real speed.
Analysis of the Speed of Cyclists Aged from 10 to 15 Years
Valentová, Hana ; Semela, Marek (referee) ; Bradáč, Albert (advisor)
The thesis is concerned with an analysis of speed of bicyclists in age between 10 and 15 years. The thesis examines differences in construction of children's bikes, describes relationship between a child and a bicycle, messures size of children's bikes and characterizes the procedure during an analysis of bike accidents. Internal parts of the thesis are statistical data from accident frequency and summarizing of actual state of understanding of following problems in this age category. The main purpose of this thesis is to make an analysis of speed for individual age categories and make an evaluation of results. This measurement will be completed by a measure of achievable brake deceleration of riders in age between 10 and 15 years. The purpose of this final thesis is an expansion of data for a forensic expertise in area of Traffic.
Train Speed on the Selected Line Section
Horák, Matouš ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
The bachelor's thesis is engaged in finfing out speed of trains in particular section of the railway track. The first part describes a direct method of measure „in situ“ and processing the data acquired this way. The second part describes the other way, namely modeling in programme OpenTrack, then follows comparison the results from this similation with real measured values.
Realization of educational problem based on experimental apparatus with cam mechanism
Tomeček, Vojtěch ; Vrbka, Martin (referee) ; Vaverka, Michal (advisor)
Bachelor's thesis is focused on solving educational problem based on experimental apparatus with cam mechanism. The task of the educational problem is to teach students to analyse kinematic quantities of cam followers. The thesis contains general discourse on the topic of cam mechanisms and basic terms definition. This is followed by putting the device into service, eliminating its particular imperfections, analysis of kinematic quantities of various combinations of available cams and followers and definition of methodics of the educational problem. The educational problem itself follows the presentation and commentary of gained results. At last some recommendations for the future modifications of the experimental apparatus are given followed by foreshadow of its eventual future usage.
Application for Practicing Rapid Reading Techniques
Sokol, Miroslav ; Seeman, Michal (referee) ; Herout, Adam (advisor)
Main goal of this bachelor´s thesis is creation user interface for correct fast reading practise. Four moduls train various abilities of human eyes in regard to average and advanced reader. Application was created as WinForm and thematically is connected with human sight, which hide incredible potential for most of people. The bachelor´s thesis analyse features of eye, individual types of exercises, implementation, concrete developement of user interface and users reactions from their own testing.
Analysis of traction drive for full electric vehicle
Matela, Petr ; Marušinec, Jaromír (referee) ; Solař, Martin (advisor)
The subject of my bachelor´s thesis is research and computations of the dynamics of different types of engines. The first part of it is devoted to theoretical introduction to electromobilism and electro mobiles history. The rest is about benefits and problems of electro mobiles, their current state and available energy sources. In the conclusion of this thesis there are all necessary calculations and the dynamics of three different engine types is solved and compared.
Speed Increasing for Track Section Bojkovice-Bohuslavice nad Vláří
Ptáček, Jiří ; Hoza, Miroslav (referee) ; Svoboda, Richard (advisor)
This thesis will examine possibilities of increse speed on a railway track section between Bojkovice - Bohuslavice nad Vláří. The increase of speed will examined according to contemporary geometric parameters of the railway track and with proposed changes of geometric parameters of the railway track. The proposed changes cannot profoundly transformate the body of the railway track. In both cases a restriction of speed by level crossing, a track branching ect. will be taken into consideration or will propose changes of these objects.
Distance and Speed Measurement Based on Ultrasonic Transmitters and Receivers
Šumbera, Adam ; Růžička, Richard (referee) ; Strnadel, Josef (advisor)
This thesis is engaged in measuring of distance and speed by ultrasound, based on microcontroller Freescale MC68HC08. Describes the function blocks of whole embedded system and its physical realization. Theoretically discuses about properties of ultrasound and deals with problems paired with transmitting and recieving.
