Dynamism and Codification
Šipková, Milena
The author attempts a typology of the language variants. She stresses that as far as codification is concerned, apart from the langue changes of the social and territorial character especially the processes of structural character are important; within them it is necessary to distinguish especially the progressive phenomena.

Noise, vibration and electromagnetic phenomena produced by semiconductor converters in traction vehicles
Budek, P. ; Chmelíček, M. ; Jehlička, Vladimír ; Škramlík, Jiří
Due to the recent employment of up-to-date control electronic and electromechanical devices in cars of City Mass Transportation, new problems arise concerning the dynamics, noise, and the radiation of electromagnetic fields. Their environmental impacts, however, have not been discussed sufficiently, so far.

Bifurcation phenomena in vocal fold vibrations - experiments in vitro
Horáček, Jaromír ; Švec, J. ; Veselý, Jan
The study presents experimental investigations focused on monitoring of the non-linear vibration effects, especially bifurcation phenomena in the vibration of human vocal folds. The experiments were performed with excised human larynges excited by airflow. Sudden changes between different regimes of the vocal fold vibration were observed when smoothly changing the tension of the vocal folds. The study reveals further details on the nature of sudden changes between voice registers. The results also point out the possible relationship between regular (physiologic) and irregular (pathologic) vocal fold oscillations.

Strong non-linear oscillators modelling
Kocanda, Lubomír
Several basic features of soft impact oscillators were invented and proved by means of experiment, numerical simulation and theoretical solution. The strong and soft impact phenomena and stable grazing bifurcation crossing were explained by means of the analytical solution, as well. New methods of piecewise linear system stability investigation were designed and compare with conventional methods. Some basic piecewise linear system features were found.

Social Pathological Phenomena in Society - Public Attitudes to Juvenile Crime
Pondělíčková, Klára ; Lačev, Alek (advisor)
Tato práce je zaměřena na problematiku chování, které může vést až ke kriminalitě dětí a mladistvých. Na specifické příčiny vzniku tohoto problému, které jsou ovlivňovány působením společnosti, výchovou v rodině a osobností každého jedince. Vnímání veřejností tohoto problému a jaké jsou shledány možnosti prevence, jak na problematiku nahlížejí učitelé a rodiče. Tyto aspekty jsou obsahem teoretické části bakalářské práce. Obsahem empirické části jsou rozhovory s uchazeči a zjišťování postoje společnosti ke kriminalitě. Přiblížení jednoho konkrétního případu brutální kriminality, spáchaný mládeží v ČR. Kde jsou společností viděny rizika a jaké jsou možnosti prevence.

The guided wave phenomena in a plate and their using in diagnostics
Hora, Petr
The goal of the research described in this paper is to compare the known analytical solution of "guided waves" propagation in a thick plate with the solution obtained numerically.

Police of the Czech Republic as a fundamental component of the Integrated Rescue System and its role in the context of mass disruption of public order in the form of civil unrest.
CARVA, Pavel
Mass disruptions of public order present very dangerous social phenomena.Acting as a public authority warranting that these situations are handled whenever they arise, the Police of the Czech Republic need to proceed in such a way as to prevent large-scale damage to health and property and ensure that protected interests are well secured as far as possible. The following two objectives are defined in the Introduction to the present thesis. To identify social changes and changes to legislation affecting the work of the Police of the Czech Republic in ensuring internal security of the State, with special regard to ensuring public order during civil unrests. To draft a guideline serving as a basis for the Police of the Czech Republic to define a standard used to improve its procedures in tackling civil unrests. As the Police of the Czech Republic represent one of the component parts of the Integrated Rescue System (IRS), the introductory part gives a brief account of the history and component units of the IRS. This is followed by a detailed description of the organisational structure of the Police of the Czech Republic, ranging from the Police Presidium and services having a republic-wide competence to Regional Police Directorates. Moreover, an account is given of riot police forces, including their history, development, organisation and training, as well as of the history and activity of anti-conflict teams. As a basis for methodology used to achieve the above-defined objectives, a sufficient amount of documents, coming mainly from internal sources of the Police of the Czech Republic was collected and thoroughly analysed, and a research into foreign and Czech legislation relating mainly to mass disruptions of public order was carried out. A qualitative research was used to gather data on the number of interventions by the riot police forces and anti-conflict teams in each year and with regard to each security measure, and an analysis of these phenomena was undertaken, including above all the events in the Sluknov Headland in 2011 and Ceske Budejovice in 2013. The qualitative research was further applied in the chapter describing the historical record of mass disruptions of public order in the Czech Republic, and in describing how the Police of the Czech Republic perceive these phenomena in terms of their gradual evolution and related social changes. The data collected in relation to foreign and Czech legislation on mass disruptions of public order were evaluated, as was the approach of the Police of the Czech Republic toward tackling these kinds of situation. Based on the defined objectives, the following research question was formulated: Do the Police of the Czech Republic have to respond to social changes and changes to legislation that are deemed to alter their procedures in maintaining public order? The research carried out along with the analysis of the collected data showed that the Police of the Czech Republic should indeed respond to social changes resulting from mass disruptions of public order, ranging from the "techno-party" type of events and spectator violence to the actions of extremists who become increasingly better organised and prepared to stand up against riot police forces, particularly whenever such events involve national minorities. Changes to legislation, such as the adoption of Act No. 273/2008 Coll., on the Police of the Czech Republic, as amended, or amendments of certain legal norms or internal management acts change the procedures and organisation of the Police of the Czech Republic related to tackling mass disruptions of public order, and the Police of the Czech Republic have to respond to them. The thesis includes a draft guideline that will serve as a basic tool for the Police of the Czech Republic to deal with mass disruptions of public order, especially at the stage of preparation, deployment of forces and means and appointment of command crews.

Selected heat transfer phenomena in air conditioning
Vojkůvková, Petra ; Gebauer, Günter (referee) ; Šikula, Ondřej (advisor)
Numerical simulation is a scientific method used to describe characteristics of examined system by means of experiments on its mathematical model. This thesis uses this method to elucidate the processes taking place in two different systems. Firstly it deals with the design of air conditioning systems for buildings, focusing on the mixing chambers. It focuses on the formation of condensation of water vapor in mixing chambers under conditions where the final temperature of the mixture does not drop below the saturation curve. Second prepared topic falls within the field of thermodynamics applied in food production. In order to assess the sufficiency of air-cooling method examines the thermal field in the product and evaluates the application of air-cooling assembly line in practice.
