Noise and vibrations of roots blowers
Smrček, Martin ; Hájek, Petr (referee) ; Švancara, Pavel (advisor)
This thesis is concerned with the spread of noise in the housing sets blowers, blower vibration, due to the shape of the geometry of the individual parts of the blower and the design of a suitable discharge muffler in order to achieve the highest possible attenuation. Analysis blower and silencer discharge was conducted using the finite element simulation ANSYS 15.0

Unconventional methods of increasing power of internal combustion engines
Smrček, Martin ; Pech, Ondřej (referee) ; Štětina, Josef (advisor)
Nowadays the most common method for increasing the performance of internal combustion engines are most used chip tuning or expanding presence of ethanol. The aim of this thesis is to perform a basic analysis of the thermodynamic cycle internal combustion engines, various effects on the thermodynamic efficiency and performance and analyze various methods to additionally increase the performance of the engine. The following are the principles of the analyzed methods, advantages and disadvantages, compared to the methods used in terms of use, price / performance ratio, as well as practical application examples.

Measuring SPA in an organization providing IT services
Smrček, Martin ; Novotný, Ota (advisor) ; Streit, Karel (referee)
This diploma work concentrates on metrics for providers of IT support. Its origins are in a project for DHL IT Services. This company has recently moved centre of support for IT services serving to logistic giant DHL in EMEA region to Prague. The goal of the project was to find suitable metrics for measuring support requirements of IT services and productivity of people who provide the support. The objective of this paper is to introduce reasons for creation, principles, benefits, risks and experience from pilot implementation newly developed metric Support Point Analysis (SPA). To meet all objectives, the diploma was split into three integral parts. In the first part there are briefly summed general theoretical theses about metrics in IT, in the second part all aspects of the metrics Support Point Analysis were described in detail. In the last part there is analysis of possible areas of using SPA. There is also experience from pilot implementation in DHL IT Services write down in the last part. The main benefit of this paper consists in evaluation of SPA results and analysis of its strengths and weaknesses. Besides there are suggestions of possible ways of SPA further development.

METRIKY IS/IT
Smrček, Martin ; Zámečníková-Rydziová, Jana (advisor) ; Klíma, František (referee)
Cílem této práce je vytvořit ucelený přehled metod používaných k měření IS/IT. Protože jsou tyto metriky často zabudované do komplexních metodik řízení, věnuji se částečně i jim. Konkrétně přibližuji metodiky ITIL, COBIT a Balanced Scorecard. Sestrojil jsem tabulku, ve které tyto manažerské návody srovnávám z mnoha různých pohledů. Hlavní přínos této práce spatřuji v komplexním zpracováním tématu. Jsou v ní použity moderní názory tuzemských i zahraničních odborníků. Proto by zejména těm, kteří se v této oblasti příliš nevyznají, mohla pomoct s orientací.
