Analysis of traffic lanes joining processes
Mikolášek, Igor ; Všetečka, Martin (referee) ; Holcner, Petr (advisor)
The aim of this paper is to analyse the behaviour of the traffic flow at an area of merging traffic lanes where an application of the zip rule is expected, accoding to the law no. 361/2000 Sb. “o provozu na pozemních komunikacích”. Žabovřeská street, part of the VMO Brno, in the direction from Královopolské tunely to Hlinky interchange was chosen for observation and measuring. Observation, first-hand measurement, radars, and other available means were used for data collection. On the basis of data analysis, several suggestions for improvements are made. These are aimed at increasing the bottleneck capacity. One of the suggestions is tested in a simulation program Aimsun.

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.

Comparison PHP frameworks for development web application
Haška, David ; Vencovský, Filip (advisor) ; Mittner, Jan (referee)
This Bachelor thesis is focused on comparison two PHP frameworks, Nette and Laravel. I have chosen version of frameworks from 4. 3. 2016. Both frameworks are compared to the development of two identical web applications because I want the most accurate comparison. Furthermore, there are investigated the qualitative requirements when I obtain information from public sources. The main output of the thesis is to compare and measure user friendliness and comfort when using these frameworks and also find out which framework is better in terms of performance and security. The work is divi-ded into two parts. The first part is a description of the methodology and comparing the actual measurements. The second part is the actual measurement made on the basis of applications along together with a comparison on the basis of the information from public sources.

Development of mobile flowmeter
DITRICH, Vít
This thesis contains the description of well-known methods and principles dealing with the measurement of the flow-velocity of fluids. Furthermore, it contains the description of the development of the mobile flow-meter, including the realization and the technical description of the device. The thesis describes the advantages and disadvantages of the above mentioned flow-meter. The last part of the thesis is dedicated to the calibration of the device and to the possible practical use of the flow-meter.

Design and verification of training sprinter
TŮMA, Pavel
The goal of the diploma thesis is the design of a training program for sprinters and verification of the training by physical metrics. Experiment is method, which was used in this work. The experimental and testing period lasted from February to June 2013. In the theoretical part, we present the history of sprinting, the various sprinting disciplines, the means of energy supply for sprinting performance and training for the various disciplines. In the practical part, we deal with development of the training plan and evaluation of this plan. Analysis of the results then confirms the hypothesis. There have been improvements in tests of speed, power, reflexes and endurance following the training program. Training plan was successfully authenticated.

How predation risk affects the growth and development of dragonfly larvae?
PEROUTKA, Miroslav
Predation and prey responses to predators in aquatic environment are reviewed with emphasis on non-lethal effect of predators on prey life history, antipredator behavior and related mechanisms. The review focuses on dragonfly larvae and other groups of prey with complex life histories, mainly anurans. The review is complemented by laboratory experiments examining the effects of varied food availability and predation risk on a selected species of dragonfly, Sympetrum vulgatum.

Coarse-grained particles conveying along a pipe bed
Vlasák, Pavel ; Chára, Zdeněk ; Konfršt, Jiří ; Kysela, Bohuš
The paper describes the results of a flow visualisation of model coarse-grained fully stratified particle-water mixtures. Investigation was focussed on study of the particle behaviour and carrier liquid and conveyed particles local velocities. Glass balls and washed graded pebble gravel of mean diameter of 6 mm were conveyed by water in a horizontal smooth pipe loop with a transparent pipe viewing section of inner diameter 40 mm. Particle movement along the pipe invert and particulate stationary bed, created by two layers of spherical particles of the same size as the conveyed particles, was studied. The effect of stationary bed on local velocity values of the carrier liquid and conveyed particles were determined. It was conducted that the maximum liquid velocity is significantly shifted from pipe centre to a higher position in the flow pattern with stationary bed.

Comparing motional abilities of Czech streethockey extraleague players
GÄRTNER, Tomáš
The aim of this bachelor?s theses is to find out the level of motional abilities of the Czech streethockey extraleague players with the help of the standardized tests. The testing battery contains two tests for speed and two tests for endurance. All players are to pass the tests in the end of summer preparation when they can show the highest level of performance. All trainers will get a special form where they will have to pud down all data necessary for the bachelor?s theses. All information will be processed and compared. In the end the work will confirm or disprove predetermined hypotheses.

Radar speed meter used in the Czech Republic
THIERBACH, Petr
Bachelor thesis "Radar speed meter used in the Czech Republic" deals with measurement of the speed in the infrastructure in the Czech Republic. First, the history of speed measurement is described. The following chapters describe the physical phenomena that allows measurement as well as phenomenon that must be eliminated. The next chapter is focused on the accuracy of meters in the dependence on meeting basic conditions for determination of measurement station and connected unfavourable influence. In the work two of most used types of apparatuses are described (AD9 C from the company RAMET C.H.M. a.s, Česká republika a UltraLyte 100LR from the company Laser Technology, Inc. USA) - they differ with each other, especially in the used technology and some components.
