Multimedia communication
Vondra, Zdeněk ; Horný, Stanislav (advisor) ; Skrbek, Jan (referee) ; Jurášková, Olga (referee)
Multimedia is a form of communication and sharing knowledge using synergic effect of parallel connected communication channels. Its main use is in producing communications products and services and in design of user interfaces. Main objective of this dissertation is to develop and create a model of multimedia communication for better understanding of the meaning and the purpose of using multimedia forms in communication process. The model will describe a system of elements and parameters of multimedia communication within the internal and external context. Another objective of this dissertation is to develop multimedia communication methodology that will be used for the design, development and evaluations of concepts of multimedia communication. The methodology will be created by applying the model of multimedia communication into the procedure structure. In theoretical way this dissertation is based on analysis of different definitions and approaches to the multimedia communications topic. This is followed by an analysis of communication theories, concepts of media, multimedia, delivery channels, and communication functions. The theoretical part is followed by the outcomes of the research in practice of four different fields of multimedia use. The knowledge gained is analyzed in the following parts in purpose of creating the model of multimedia communication and the methodology which is derived from the model. The methodology is further validated through case studies and the recommendations for further development are formulated. The model and the methodology of multimedia communication created in this dissertation present complex view on multimedia communication topic that is considered as a useful tool for meeting a specific communication purpose. Dissertation provides mechanics for use and study of multimedia communication and also defines the opportunities for further development of the methodology.

A Comparison of Preconditioning Methods for Saddle Point Problems with an Application to Porous Media Flow Problems
Axelsson, Owe ; Blaheta, Radim ; Hasal, Martin
The paper overviews and compares some block preconditioners for the solution of saddle point systems, especially systems arising from the Brinkman model of porous media flow. The considered preconditioners involve different Schur complements as inverse free Schur complement in HSS (Hermitian - Skew Hermitian Splitting preconditioner), Schur complement to the velocity matrix and finally Schur complement to a regularization block in the augmented matrix preconditioner. The inverses appearing in most of the considered Schur complements are approximated by simple sparse approximation techniques as element-by-element and Frobenius norm minimization approaches. A special interest is devoted to problems involving various Darcy, Stokes and Brinkman flow regions, the efficiency of preconditioners in this case is demonstrated by some numerical experiments.

Diet of patients with ulcerative colitis
KOŘÍNKOVÁ, Lucie
This bachelor thesis deals with ulcerative colitis as well as with the impact of such a disease on patient's diet. The aim of this thesis is to describe the composition of the diet of patients with ulcerative colitis. The following research questions are defined: "How do the patients follow the principles of a proper diet in this disease?", "What foods do the patients tend to avoid most often?" and "What is the experience of selected patients with a nutritional therapist?" At first, this bachelor thesis summarizes theoretical knowledge of the current status, incidence, diagnostics, causes and the course of the disease. Other chapters deal with symptoms of ulcerative colitis which is not just a matter of the digestive tract. This is followed by the extraintestinal complications that are related to the disease. The nutritional status of patients is also mentioned here. Last but not least, this work describes the diet plan of patients. To achieve the goal of this thesis, quantitative and qualitative researches are selected. The quantitative research is conducted using questionnaires which were distributed to patients of the Clinical Centre ISCARE I.V.F a.s., that is under the leadership of a head of the department, Prof. MUDr. Milan Lukáš, CSc. The survey results are presented in the form of graphs. The qualitative research is carried out through the recording sheet to which the selected respondents wrote down their two-week diet. This diet was subsequently evaluated in the program Nutriservis. The results were compared with the recommendations and interpreted in the form of tables and plain text. For comparison, a general sample menu for the period of remission has been worked out. The research results show that eating habits of patients are quite stereotypical. Generally known facts have been confirmed. Most frequently, patients try to avoid the consumption of dairy products, wholemeal bread and legumes. The consumption of vegetables, fruits and fish is not sufficient. Patients are not aware enough of the role of a nutritional therapist, most respondents do not have any personal experience with him. Dietary advice is searched on the internet where some unverified recommendations may endanger health of individuals of malnutrition, hypovitaminoses or deficiency of trace elements. However, patients in the remission stage of ulcerative colitis should follow the rational diet with regard to individual food intolerance.

Marketing Strategies in Fashion Industry
Čmielová, Zuzana ; Král, Petr (advisor) ; Richter, Stanislav (referee)
The goal of this thesis is to define the fashion industry and identify the key developments that the segment has undertaken over the last two to three decades including the drivers behind these changes. Specifically, the thesis will provide insights into the financial indicators of the industry and review some of the most recent trends such as globalisation of supply chains and internationalisation of fashion retailers. The second section of the theoretical part will try to identify what are the characteristics of fast fashion customers and what influences motivate their shopping behaviour. Specifically, some of the academic concepts will be examined and put into the context of fast fashion -- these include fashion involvement and fashion consciousness, the influence of opinion leadership and the trend of social shopping. The latest part of the theoretical section will examine the contemporary marketing strategies in the fast fashion segment some of which has been spread over the whole fashion market. Amongst the most vital ones is the change in supply chain management strategies, the shortening of the fashion life cycle and its impact on the frequency of stock replenishment. In addition, the theoretical part will examine the rising power of the internet, its effect on online shopping and the overall transformation of media towards digital communication with the growing influence of fashion bloggers. The goal of the practical part of the thesis is to conduct extensive analysis of the fashion strategies of the two selected fast fashion retailers -- Zara and H&M. These were chosen on the basis of their global success and outstanding financial performance even in the period of economic downturn which makes their strategies unique and worth analysing. Each brand has a distinct approach to its marketing strategy and in many of the elements they are fundamentally different, yet both approaches has enabled the brands to achieve international success and build highly profitable businesses. To review the complexity of different aspects of their strategies, the 7p's framework will be used.

E-recruitment
Mesteková, Marie ; Šerák, Michal (referee) ; Kocianová, Renata (advisor)
This bachelor thesis's goal is to provide a complex conception of the possibilities of E-recruitment in the Czech Republic in the context of abroad experiences and know-how brought to the Czech Republic by external organisations. The work is conceived to cover aH elements which are participating in workers recruitment: organisations themselves and candidates as weH as personal placement services. The roles of these agents are defmed and it is described how these roles are modified by the usage of the Internet in the human resources sphere. Inc1uded are the areas of workers recruitment as personal marketing and its possibilities on the Internet, getting references with the help of Internet s earching , intranet and workers acquisition from internal sources are. The endeavour is to guess the development on the basis of Internet exploitation in human resources sphere development abroad, main1y in the western countries. The focus is on the phenomenon of social networking and its usage in human resources as of a very efficient source or even database of candidates.

Optimization analysis of brake wheel
Hrabovský, Jozef ; Vlach, Radek (referee) ; Houfek, Lubomír (advisor)
Subject of this diploma thesis is break wheel optimalization analysis. Break wheels are used in mountain bike downhill races in extreme conditions. It is the first product of this type of an emergent company that was made by the use of intuitive approach. The reason for optimalization is improper behavior of existing solution that occurred during testing. This optimalization consists of finding and analyzing existing characteristics, deciding which factors influence this improper behavior, suggesting new solution and verification of this solution. Break wheel characteristics were detected in an experiment. For realization and evaluation of this experiment, a method named Design of experiments, was selected. This method is used for elaboration of results coming from the Regression analysis. It is possible to effectively achieve the result data by using this procedure. The experiment was oriented to gain data of temperature behavior of break wheel during real load. Mathematical model was adapted on the basis of this data and finally, the calculation was made by the use of Final element method by ANSYS WORKBENCH. Calculations were also coordinated through Design of calculation, and were oriented on temperature deformation and stress. Solution achieved by the Final element method, was evaluated by the Regression analysis and served as a proposition for a new break wheel construction.
