Single-Phase Induction Motor Calculation
Ševčík, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
This master's thesis considers by single-phase asynchronous motor. The first part discuss about construction, principle of operation and basic parameters of this motor type. It also discussed the emergence of torque and torque characteristics of the different types of engines. The second part explains the basic ways of obtaining grip moment including outline the principles of functions particulars constructions types, which is produce in practice. In the third part is minutely analyse single-phase asynchronous motor with auxiliary phase and permanently conect capacitor, including method of assign size of a capacitor. Fourth part section provides the principles of the procedure for calculating basic parameters of the single asynchronous motor with auxiliary phase. At the last part is accomplished a calculation of single-phase asynchronous motor with permanently conect capacitor at auxiliary phase including comparation with already manufacturing motor.

Antisemitic memes on 4chan.org
Feistinger, Aleš ; Vochocová, Lenka (advisor) ; Nečas, Vlastimil (referee)
In my thesis I address three questions: 1. What are the principles of memes? 2. What categories of anti-Semitic memes can we identify on 4chan.org? And 3. how do they relate to existing knowledge about anti-Semitic propaganda? To answer the first question, I review current theories ranging from active audiences, through Internet memes, to the interaction of memes and politics. Furthermore in the theoretical section, I describe the website 4chan.org (including its boards /b/ and /pol/) and the current form of anti-Semitism on the Internet. For the research of the second question, I have identified semiotic analysis, complemented by grounded theory, as the most appropriate methodology. I present its methodology and practical use, followed by presenting results including subcategories and illustrative examples. The thesis concludes by integrating the most important findings into current knowledge and anti-Semitism and thus answering the third research question. Finally, the main findings are summarized.
