Experimental study of spray characteristics and functionality of small pressure-swirl atomizers
Malý, Milan ; Lízal, František (referee) ; Jedelský, Jan (advisor)
Diplomová práce se zabývá experimentální studií vlastností spreje z několika malých tlakových vířivých trysek používaných ve spalovacích komorách proudových motorů. Po desetiletí byla snaha zlepšit jejich rozprašovací charakteristiky a stále jsou možnosti, které nebyly téměř prozkoumány. Výzkum byl proveden za použití různých geometrií jednotlivých dílů trysky za účelem zjištění jejich vlivu na sprej. Byl použit různý počet vstupních portů (2, 3 a 4), různé vířivé komůrky (kulová, kuželová, konvexní, nízká kuželová) a rozdílné návrhy obtokového otvoru (osové, mimosové). Důraz byl kladen na posouzení stability spreje, kde pulzující sprej negativně ovlivňuje provozní charakteristiky spalovací komory. Vlastnosti spreje byly proměřeny fázovým dopplerovským analyzátorem, cirkulární homogenita byla hodnocena mechanickým paternátorem a rozpad kapaliny byl vizualizován pomocí jednoduchého laserového stínografu.

Processing and analysis of HS videorecords of liquid atomization for a pressure-swirl nozzle
Červenec, Adam ; Lízal, František (referee) ; Jedelský, Jan (advisor)
This bachelor thesis deals with processes of liquid atomization for a pressure-swirl nozzle. The main goal was to study liquid cone, which is gradually fragmenting on smaller parts ending in creating small droplets. It was needed to study theory of liquid flow, motion of droplets and an impact of the geometry of nozzle. When the theoretical part ended we could perform an experiment, which consists of preparing devices and creating own video records using highspeed camera Photron FASTCAM SA-Z. The camera provided us detailed view on the spray and events, for example collisions of droplets, which are the main subject of this thesis. Afterwards the video records were analyzed and we could provide results connected with studied problem.

Use of Family Mediation in Resolving Post-breakdown Conflicts
KUBKOVÁ, Lucie
The diploma thesis deals with the use of family mediation in resolving post-breakdown conflicts. The aim of the diploma thesis is to describe the use of family mediation in resolving post-breakdown conflicts. The thesis is divided into two parts - theoretical and practical one. The theoretical part, which is divided into four chapters and subsequently subchapters, defines basic terms such as mediation, its principles, styles and techniques, family mediation and its phases, the role of the mediator, participants in family mediation, breakup and conflict. The practical part is processed using the qualitative research strategy, interviewing method and semi-structured interview technique. The interviews were conducted with six family mediators from non-profit organizations in the South Bohemian Region. The questions that were asked to the respondents were chosen to evaluate the research questions. The research revealed that family mediation can be used for various post-breakdown conflicts, but the form of the mediation process is very individual, because it always depends on the situation and the participants of the mediation. Families can only be approached similar and similar techniques can be used. Although mediation has almost no disadvantages, there is still low awareness and low interest in using this alternative dispute resolution in society. The results of this thesis can serve as a source of information about how family mediation can look like in practice. The obtained data can be used in articles about family mediation or to increase the awareness of students helping professions and public about family mediation and better orientation in it. The obtained informations can also serve as an inspiration or as feedback for family mediators.

The Atmosphere in the Czech and Slovak Society after the Breakup of the Czechoslovakia: The Event in the Context of Comments in the Broadcasting of the Czech and Slovak Radio (1.1.-31.12.1993)
Kobrlová, Eva ; Lovaš, Karol (advisor) ; Maršík, Josef (referee)
This diploma thesis aims to convey the atmosphere in the Czech and Slovak society at the time of the Breakup of the Czech and Slovak Federal Republic. For this purpose, comments broadcasted by Czechoslovak Radio, Czech Radio respectively, and Slovak Radio were analyzed. The author collected all such comments connected with the breakup of Czechoslovakia between the 1st of July, 1992, and the 31st of December, 1993, regardless of whether these comments focused on the defense, criticism, causes, or consequences of this event. For the analysis itself, the method of analytic induction was used. To put the issue into a broader context, the analysis itself is preceded by a brief overview of events related to the breakup of Czechoslovakia in the period under review. The overview is followed by a description of how the event was perceived by Vladimir Mečiar and Václav Klaus, leaders of the two most powerful political parties in Czechoslovakia at that time and, therefore, the main figures of the breakup. The description is based on their publications and social outputs. To give an insight into the atmosphere mainly in the media under review but also into the atmosphere in the Czech and Slovak society, the perspective of Anna Sámelová and Jan Pokorný, journalists working in the mentioned media at that time,...
