Gravital conveyor for transport
Fatka, Milan ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The aim was to propose a conveying gravity path for the transport of steel casting in the context of inter-transfer service. The conveyor is dealt with valid norms with regard to simplicity of design, production and assembly (disassembly) with broad use of standardized parts. It was also seen to be done to take advantage of the proposal in solution of similar specification.

Design of electric tackle
Bádr, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
Purposes work was create technical documentation to an electrically driven tackle with actuated by hand undercarriage. Was booked up fundamental parameters like bearing, stroke and hoisting speed. First was effected calculation of load on pinion necks and an idle pulley. Subsequently was effected calculation for right election of a rope, an idle pulley, a rope drum and bearings for the rope drum. Up this calculation followed calculation for a right election of an electric motor and a shaft clutch. The documentation was complemented with pictures and tablets, that are seted near single decisive knots of the tackle. To the documentation was creationed how a suggested arrangement drawing so single subassemblies drawings.

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.
