Conjunctions in Spoken and Written Czech
Tartakovskaya, Anastasia ; Cvrček, Václav (advisor) ; Hudousková, Andrea (referee)
TARTAKOVSKAYA, A. Conjunctions in spoken and written Czech Faculty of arts Charles University in Prague, 2011 Supervisor: Václav Cvrček, Ph.D. Number of pages: 66 + 6 attachments Key words: Conjunctions, written Czech language, spoken Czech language, word link, Czech National Corpus, secondary linking conjunctions, co-coordinating linking conjunctions Conjunctions in the Czech language are still relatively small chapter described in manuals and grammar books. The aim is to investigate connecting words in spoken and written language, their use in text and links with other words, compare the use of the coupling term in written and spoken Czech language. Theoretical basis for master's thesis is based on several works which are devoted to this issue, either in whole or in dealing with some of its parts. But the major outline of work is driven by the Czech National Corpus (hereafter CNC), namely the corpora SYN2005 and ORAL2008. First chapter deals with CNC and coupling expressions in general, second deals with secondary linking conjunctions, their use in text types and surrounding words. The content of the third chapter incorporates the connecting conjunctions.

A comparative study of the Czech lexeme "aby" and its English translations in parallel Czech-English texts
Vašková, Petra ; Klégr, Aleš (advisor) ; Tichý, Ondřej (referee)
The present study focuses on functions and English translation counterparts of the Czech lexeme aby. It is a relatively frequent word in the Czech language which is described as a subordinating conjunction expressing purpose, effect, manner, and also as a particle with a number of discourse functions. The current description, however, does not seem complete and this study therefore aims to analyse its use in more detail. Lexicographic and grammatical sources served as a basis for the classification of aby as a conjunction and as a particle. After an analysis of 200 examples it soon became evident that this listing is not complete and the use of aby is more complex than originally expected. The present paper thus treats all the functions of aby and also exemplifies each of them using extracted corpus data. In the study, aby in its conjunction and particle use is firstly treated separately to analyse each of them in more depth. This analysis, consequently, provides basis to point out their common features as well as their differences. The English translational counterparts are another point of interest in the study, in particular, their adequacy, regularity, and lexicalization.

Study of torque vectoring clutch design
Cupák, Václav ; Porteš, Petr (referee) ; Fojtášek, Jan (advisor)
This work deals with the design of right and left torque vectoring control used in heavy commercial vehicle powertrains. The beginning of the work is focused on the description of the active differential system and on the clutches used in the automotive industry. Then the basic parameters of the experimental vehicle are defined and the choice of the clutch conception is made. Subsequently, calculations of geometric parameters of clutches and verification of their heat capacity is made. Conceptual design of the control mechanism is discussed in the last chapter. The aim of the work is the draft of the possible type of control mechanism for the given system with the possibility to use the information obtained for the further development of this system.

Design of magnetorheological clutch.
Nováček, Vladislav ; Dočkal, Aleš (referee) ; Roupec, Jakub (advisor)
This thesis deals with the design of the magnetorheological (MR) clutch. The extensive literature research with particular conclusions to each design variant of MR clutches or brakes has been done in the first part of the thesis. The second part of the thesis describes the design of the actual MR clutch based on the results of the analytical calculation of the magnetic circuit. Finally, the experiments verifying the function of the key segments of the clutch, and the whole clutch are summarized in the third part of the thesis.

Using brushless d.c. motor to drive servo-unit with safety function
Rudolf, Ladislav ; Mišurec, Jiří (referee) ; Prajzner, Václav (advisor)
In this work, a proposal for BLDC motor control, which will be used as a drive linear actuator. Control with microcontroller focuses mainly aspects such as motor mode, regenerative mode, measuring rotor position sensors and measuring the motor current, which corresponds to the moment. The result of the work is focused on upgrading the existing Honeywell actuator, where the processor-controlled BLDC motor to replace the existing system and take over the actuator working function and emergency function.

Design of MR clutch water cooling
Musil, Marek ; Strecker, Zbyněk (referee) ; Roupec, Jakub (advisor)
This paper describes the design and manufacture of water refrigeration for magneto clutch. MR clutch cooling problem was solved by designing of several variants of which was finally chosen the best. Model of water cooling was developed and subsequently made. The cooling is consolidated on a stator of MR clutch. Cooling completely surrounds the body of an MR clutch and thus achieves a high heat transfer between the cooling system and cooled. The proposal was developed with a view to good foldability, so its use is not complicated.
