Effect of voltage variant of a frequency converter on asynchronous motor parameters
Pavlas, Michal ; Bílek, Vladimír (referee) ; Bárta, Jan (advisor)
This bachelor thesis is focused on literature researches, dealing with the properties of controlled drives with asynchronous machines. The work describes the possibility of operation of a three-phase asynchronous machine directly powered from a single-phase network without a frequency converter. In the next part, the research is focused on a theme dealing with the influence of harmonics of the converter on the parameters of an asynchronous motor. Subsequently, specific test methods for determining the losses and efficiencies of AC motors powered by frequency converters are described on the basis of the IEC 60034-2-3 standard. The last part of this bachelor thesis is devoted to the assessment of the influence of the voltage variant of the frequency converter on the parameters of the asynchronous motor.

The Commercial Real Estate Analysis for CEECs region
Pavlas, Michal ; Hlaváček, Michal (advisor) ; Kvaček, Jan (referee)
In this thesis we examine macroeconomic factors that influenced the office real estate market in CEE countries between years 2000 and 2012. First, we describe commercial real estate indicators. Next, we create several models for four cities - Prague, Budapest, Moscow and Istanbul. We make also panel data regression for all four cities. We conclude some key determinants that influence the prime yields of office buildings in each city and finally we compare and contrast the results across all cities. Our results suggest that prime yields are most influenced by vacancy rate, gross take-up, total office stock and unemployment rate.

Strategický rozvoj společnosti komerčních nemovitostí KCRE: CEE expanze v internacionalizačním rámci
Pavlas, Michal ; Jaklová, Martina L. (advisor) ; Tomas, Kubiny (referee)
Primary aim of this master thesis is to depict an emergence of a professional service firm performing its' activities on the commercial real estate market in the Czech republic and to project future development in CEE region confirming existence of factors leading to fast internationalization of a professional service firm concept with specific attention to a born global concept. The work aims to identify factors of a PSF growth in various dimensions and in various specific markets as well as best practices of other globally operating structures. While the theoretical part of the thesis presents principles of a professional service firm's (PSF) function, commercial real estate market and internationalization, the practical part assumes application and implications for the company Kenoby Group ltd. (KCRE). The academic enrichment of research is derived from the three-dimensional interconnection of the concepts of Professional Service Firm, Commercial Real Estate and Internationalization, Born Global respectively.

Strategie vstupu české firmy na zahraniční trh
Pavlas, Michal ; Turnerová, Lenka (advisor) ; Khelerová, Vladimíra (referee)
Bakalářská práce se věnuje strategickému rozvoji malé, globálně operující společnosti se zacílením na potenciál indického trhu. V teoretické části shrnuje teorii vstupu firem na zahraniční trhy s přihlédnutím k otázkám, které si musí před expanzí společnost zodpovědět. Navazující praktická část ověřuje předpoklad o vhodnosti indického trhu pro expanzi mobilní technologické společnosti Creativo Techologies s.r.o a na základě komplexní analýzy vyhodnocuje přínosnost, ale také komplikace vstupu. Základním nástrojem praktické části práce je výzkum od stolu, tedy využití veřejných a soukromých databází, oficiálních vládních zdrojů atd. Konečným úsudkem je doporučení strategie expanze s časovým rozdělením.
