Optimization Of Selected Proposed ČSN Elements For Road Design
Kokeš, Ondřej ; Čepil, Jiří (referee) ; Radimský, Michal (advisor)
Diploma thesis describes and researches some proposed ČSN 73 6101 elements for road design and their subsequent comparison with Norma de Traçado that is main law for road design in Portugal. In practical part, the speed of vehicles during moving on direction curves is researched and subsequently coherence of theoretical assumptions with real speeds is compared. The main aim of this work is to verify the assumption that design speed does not correspond to the real speed that drivers move on road structures.

Design Of I/34 And II/164 Crossroad Near Jindřichův Hradec
Kokeš, Ondřej ; Krčmová, Iva (referee) ; Radimský, Michal (advisor)
This is an adaptation of the existing intersection, which their arrangement is unsatisfactory and there is becoming a serious accident. This work proposed three options. In the first variant is proposed the roundabout. The proposal is located in the existing conditions, to prevent expansion of plots. In the second variant is designed turbo roundabout with spiral arrangement of lanes. This proposal also uses space in the existing condition. In the main direction of the traffic intensity is designed bypass. The third variant is designed as joining intersection, which is also located in the existing conditions. The focus of the third option is to change the main traffic routes and design of the connecting and cornering lane.

GPS position recording system
Kokeš, Ondřej ; Magát, Martin (referee) ; Kadlec, Jaroslav (advisor)
The system conducting an electronic record of drives employing GPS enables simply track the vehicle running and traffic. As vehicle is running, information is gathered and saved into the memory module, out of which the driver's report book is generated afterwards. The submitted work is involved in brief summary of possibilities that might be used during implementation of the project and furthermore during complete solution of such a system, hardware and software parts included.

Microposition control device
Kokeš, Ondřej ; Bajer, Arnošt (referee) ; Kadlec, Jaroslav (advisor)
Presented thesis analyses a function of the particular type of the nanopositioner with aim to suggest and construct an electronic device suitable for control of the nanopositioner slider. In presented material there is a description of the control signals and possibility of their generating in the respect of slider movement accuracy. The main goal of the thesis is to describe electronic units ranging from power supply, control processor unit part to end part that directly joint nanopositioner. There is also programme equipment for microcontroller and computer, communication description, movement measuring and calibration and draft for the close-up of the control loop for additional increase of the movement accuracy.

Income Elasticity of Gasoline Demand: A Meta-Analysis
Kokeš, Ondřej ; Havránek, Tomáš (advisor) ; Avdulaj, Krenar (referee)
In this thesis I summarize previous studies estimating income elasticity of gasoline demand, analyze the models employed, comment on the evolution of econometric tools used, and finally perform a meta-analysis. This thesis is the first survey on gasoline income elasticity that takes into account publication bias. It also distinguishes between models including car stock information in estimation. I estimate the underlying short-run elasticity to be 0.1, long-run with car stock 0.234, and long-run without car stock 0.644. These results, on average, point to less income-elastic demand for gasoline than what previous surveys found.

Evaluation of Gold Market in China
Kokeš, Ondřej ; Stará, Dana (advisor) ; Srbek, Pavel (referee)
The Chinese gold market has become the number one spot for gold trading and it will keep the strong momentum in the future. This would not be possible without the blessing of Chinese authorities, notable governmental agencies and economic progress. Among the factors influencing this growth are the regulations which are put in action by Chinese government through its central bank (People's Bank of China). At the time of globalisation nothing is isolated anymore. Chinese gold exchanges are taking more and more from the world's exchanges. For the thorough understanding why China has become the number one in the gold production and consumption it is important to understand its history. Without its wisdom and knowledge. It would be futile to try to comprehend why are the Chinese people so obsessed with gold and why they prefer one part of the gold market to the other. The Chinese gold market has a bright future ahead and it grows stronger every day.
