Effect of Conformity on Friction in Roller Bearing
Pisklák, Jan ; Zikmund, Vladimír (referee) ; Vrbka, Martin (advisor)
This master’s thesis describes the influence of conformity on friction in rolling bearings. The coefficient of friction is measured on an experimental machine - Mini Traction Machine 2 – using ball-on-disc method. The results are plotted in graphs which showing the dependence of the coefficient of friction at spin-to-roll ratio for specific conformity, normal load and speed in the contact area. The influence of load, speed or different lubricant viscosity is verified for a given value of conformity. Experimentally obtained data are compared with the mathematical model developed in MatLab, within this thesis.

Design of Coriolis flowmeter
Krejčí, Martin ; Zikmund, Vladimír (referee) ; Dvořáček, Jiří (advisor)
This thesis deals with the structural design of mass flowmeter based on the principle of the Coriolis force. The introduction explains how the Coriolis flowmeter operates, what types of flowmeters are currently being produced and what are the important parameters. There are appointed some of the principles that must be followed to the meter working correctly. It contains a proposal design of flowmeter for pipes DN80 and. Includes drawings for this design.

Marketing communication of sport team FK Mladá Boleslav in the years 2009-2014
Zikmund, Vladimír ; Halada, Jan (advisor) ; Orban, Karol (referee)
By introduction to marketing and applying its tools and processes in sport environment on example of communication of Czech football club FK Mladá Boleslav in years 2009 to 2014, I seek an answer for the question of sport marketing necessity. At the beginning, position of sport in culture and the place of media is defined. Sponsoring and partnership as crucial part of economic prosperity are introduced both theoretically and practically on significant examples from the world. Later on, characterizing historical, structural and sport background of FK Mladá Boleslav creates background for specifying its communicational outputs, mainly in continuously used mediatypes of online, radio and out-of-home. Also close relationship with strategic partners and sponsors, together with recent visual identity updates, does not remain unnoticed. Based on those learnings, I provide set of recommendations with main objective to increase attendance, as the output of my thesis. Thus the importance of sport marketing in Czech Republic is underlined.
