Modal verb "be" and its Czech counterparts
Tomšová, Karolina ; Brůhová, Gabriela (advisor) ; Čermák, Jan (referee)
The present thesis studies the English modal verb be and its Czech translation counterparts. The aim of this work is to analyse its Czech translation counterparts and outline the methods that are most frequently used to translate this construction. The modal verb be is examined in construction with both the active and passive infinitive as well as in the present form or the past form of the infinitive. Next, the modal verb be is analysed from the syntactic point of view as the types of sentences in which the modal be occurs most frequently are examined. The thesis consists of two parts: the theoretical background which introduces the topic of the modal verb be and the empirical part which analyses one hundred examples taken from the Parallel Corpora InterCorp. Five key areas are examined in the analysis: the modality expressed by the modal verb be, the Czech translation counterparts of the deontic and epistemic use of the modal verb be, the voice in which the infinitive in the construction with the modal verb be occurs and the types of sentences in which the modal be appears most frequently. The findings acquired in the analysis are summarized in the conclusion.

The meaning and Czech equivalents of "should" in subordinate nominal content clauses after evaluative and directive expressions
Hráská, Michaela ; Dušková, Libuše (advisor) ; Čermák, Jan (referee)
This diploma thesis examines functions of the modal verb should in nominal content clauses introduced by the conjunction that. The Czech counterparts of the English sentences are considered as well. The research focuses on the so-called putative should which occurs after main clauses with directive, epistemic, attitudinal, evaluative and volitional expressions. Should expressing intrinsic (root) modality (expressing permission, obligation or ability) is left out of account. The work pays attention to the basic classification of nominal content clauses deriving from a verbal form alternating with putative should. Two kinds of putative should will be dealt with, namely should after directive and volitional expressions which could have its alternative form in the present subjunctive and should after epistemic, attitudinal and evaluative expressions which could possibly alternate with the indicative. The work examines these verbal forms in relation to the intentional modality of the sentence in an independent form (e.g. declarative, interrogative or imperative sentence). The work is divided into two parts: theoretical and practical. The theoretical part of the work describes the basic classification of all central modal verbs in English and putative should in terms of its relation towards the...

Laboratory simulator of radial journal bearing
Vincenc, Jan ; Čermák, Jan (referee) ; Šperka, Petr (advisor)
The master’s thesis deals with a design of a radial journal bearing simulator, which is ready to implement a transparent sapphire journal bearing to an optical observation of the oil film. The first part of this thesis contains a short review of a few currently used journal bearing test rigs. The next part of the work deals with a discussion of concept variants and a definition of important parameters. The last part contains a detailed description of the designed radial journal bearing simulator. Limitations of the designed simulator and recommendations for future improvements are also discussed. The result of the presented work is the designed journal bearing simulator which will allow observing of the oil film. The work also consists a complete design documentation.

Mathematical models of military conflicts
Skopal, Martin ; Potůček, Radovan (referee) ; Čermák, Jan (advisor)
This thesis discusses the mathematical models used in the theory of warfare. The aim is to build and describe the Richardson model of conict and selected Lanchester models of combat. The models are subsequently analysed with a focus on stability. A part of the thesis is also formed by application of real data onto the models and by the subsequent evaluation of their results.

Continuous and discrete models of population biology
Fedorková, Lucie ; Tomášek, Petr (referee) ; Čermák, Jan (advisor)
This thesis analyzes the continuous and discrete logistic model of a single-species population. For both of these models, there are discussed problems of equilibria, their stability and behaviour of the solutions for different initial conditions. In the case of the discrete model, the periodic behaviour of solutions is discussed in detail with respect to change of a parameter characterizing growth of the investigated population. The chaotic behaviour of solutions is mentioned as well. The graphic interpretations of each of the problems are performed using the software MATLAB. The calculations are checked via the software Maple.

Analysis of the Rössler dynamical system
Nechutová, Vendula ; Nechvátal, Luděk (referee) ; Čermák, Jan (advisor)
In this bachelor thesis, there is analysed Rössler dynamical system, especially stability and type of its fixed points. Theoretical calculations are supported with visualizations illustrating notions of bifurcation and chaotic behaviour. In the last part, stabilization of chaotic Rössler dynamic system by delayed feedback control is discussed.

Development of a testing system for evaluation of rolling bearings with variable lubrication parameters
Škoviera, Jozef ; Čermák, Jan (referee) ; Omasta, Milan (advisor)
The presented diploma thesis deals with the design of a test system for rolling bearings, which allows the change of the lubrication parameters (e.g. changing of the relubrica-tion interval). In the document, the reader first learns about the meaning of lubrication of rolling bearings, the possibilities of lubricant supply to the bearing (specifically for the supply of grease) and the possibilities of dosing control. Subsequently in the document is described the present state of experimental stations for testing rolling bearings, which is available at the Institute of Machine and Industrial Design. The end of the part about current state of knowledge is also mentioned the possibility of speeding up fatigue tests. In the next part, the author describes his own solution. The result is the design of an experimental station (for option to relubricate with grease), the creation of a lubrication control platform and the creation of a basic program. Part of the work is also verification experiments and drawing documentation.

Lubricant film formation in compliant contact
Jaroš, Tomáš ; Čermák, Jan (referee) ; Nečas, David (advisor)
This diploma thesis deals with the study of film formation in compliant contact. Primary attention is dedicated to the influence of the entrainment speed and slide-to-roll ratio (SRR) on the central film thickness. Based on a research study of the available experimental methods, the fluorescence microscopy was used to achieve the aim of the work. Experiments were realized in ball-on-disk configuration. Firstly, a validation of the method was performed where the solid contact of the ceramic ball and the glass disk was analyzed. Since the measured values were in a good agreement with the theoretical prediction, a ball of NBR rubber material, which is commonly used for production of lip seals and o-rings, was subsequently used. The experimental measurements were performed under pure rolling and rolling/sliding conditions when the entrainment speeds varied in the range from 10 to 400 mm / s. A constant load of 0.2 N was applied. The measured data were then compared to the theoretical predictions for compliant contacts. The results showed that the thickness of the lubricating film gradually increases with increasing entrainment speed, which corresponds to theoretical assumption. Against expectations, evident influence of SRR on the film formation has been observed. In the last part of the thesis the measured data are confronted with previously published studies. Finally, some limitations of this study are discussed and recommendations for further improvement of the used experimental method are suggested.
