Habán, Tomáš ; Kropáč, Jiří (referee) ; Pavlas, Martin (advisor)
The main objective of this work is to focus on biomass as one of the components of renewable energy sources for the production of thermal energy by combustion. The introduction of work maps the current state of biomass used in the Czech Republic. It evaluates options for future uses for biomass and also the size of the potential in the natural conditions of the Czech Republic. It also views this renewable resource from the point of view of energy conception and evaluace the government positron on this issue. Next part deals with the combustion of biomass and with the use of created thermal energy. It ruminate a problem of pollutants and shows values for emission limits results from the legislation. It shows ways of using this thermal energy and the associated production of electrical energy including an overview of the possibilities of its evaluation. The last part of this work describes a comparison between biomass boilers from Czech and foreign producers in the range of rated output 1 to 3 MW. It divides boilers in terms of legislation and shows the obligations and conditions attached to the operators of biomass boilers. It outlines the biggest application of boilers with medium capacity for biomass combustion in the Czech Republic.

Solid Particle Emissions from AgroPellets Combustion
Svoboda, Marek ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This thesis is divided into two parts. The first part deals with defining the main concepts, properties of biomass and pellets. Further, the procedures for measuring agropellets properties according to valid standards are mentioned. The following is a selection of the raw materials for the production of agropellet, with the determination of their properties. The theoretical part closes background research emissions from combustion and emission standards for a solid fuel boiler. The second part is an experimental one, which determines the formation of solid pollutants in combustion of four types of pellets made from alternative sources. Here are the graphs of the gaseous emissions of each of them. At last there will be a comparison of emissions agro pellets with more widespread wood pellets.

Sports and Relaxation Centre Vsetín, Ohrada
Marková, Dominika ; Kotek, arch Jakub (referee) ; Odvárka, Antonín (advisor)
The assignment is an architecture and urban planning study of a sports and recreation center. The solved area is located in the town of Vsetín, in the part called Ohrada. Nowdays, the area is obsolete, unfunctional and also unmodern. My project is mainly focused to create a concept that responds to the environment, offers outdoor and indoor spaces for all generations. It allows better connection with nature, variable use, and division of area by function. The design is defined by the river Bečva on the west side and a busy 1st class road on the east side. It was important to separate pedestrians and cyclists from motor vehicles. The response to this restriction is to direct traffic in the area to the west, towards the river. This creates a terrain works that optically deflects the design in a quieter direction. Buildings are placed in the line and oriented in the western direction. After creating the terrain, I divided the area into several segments according to functionality. In the heart of the area, a multifunctional central hall with an inner climbing wall is set in the terrain. In front of it is a public space for meetings, sports and recreation. On the other side, there is a basketball court, a workout playground, a children's playground in front of the hall and a rest area of ??greenery closer to the river. If we continue southerly down, another cube set into the terrain is a building with a restaurant and a cafe. The southernmost building is a tennis club with facilities for athletes and squash. In front of the building there is a 9x tennis court with a grandstand. Closer to the river and the bike path there is an outdoor climbing wall. From the newly created embankment, the area is divided by a cycle path around the river. Behind the bridge is a green belt separated area which, unlike the previous ones, is tuned in a calmer spirit. We will find a building of a yoga and meditation center.

Spectral analyse of sound in space acoustics
Port, Martin ; Bereznanin, Martin (referee) ; Rozman, Jiří (advisor)
This thesis is an introduction to the problems of acoustics and is focused on the variables describing the noise. The methodology for measuring noise in relation with valid hygiene standards is analyzed in next section. The noise levels at work required by government regulation no. 148/2006 are summarized in a subsequent charter. The next section is an introduction to the analyzer PULSE 3560B from Brüel & Kjar. This work describes a software called Labshop, which is designed to analyze noise and vibrations. It also describes the most common features Acoustilyzer NTI AL1. The practical part was to measure the reverberation, noise, frequency spectrum and plott the distribution of noise with noise maps of various auditoriums.

Limity supervize u pracovníků v sociálních službách
MARTÍNKOVÁ, Nikola
The aim of the diploma thesis was: "To identify what limits perceive supervisors at group supervision meetings of social workers in social services." The main research question was: "What are the limits of supervision of social workers from the perspective of supervisors?" A qualitative research strategy, a method of questioning and a semi-structured interview technique were chosen. To achieve the goal, the main research question was divided into areas: identification (6 partial research questions), formal requirements of supervision (2 partial research questions), supervision (4 partial research questions) and benefits of supervision limits (2 partial research questions). The research group consisted of supervisors associated under the Czech Institute for Supervision (ČIS). Taking into account the set strategy, 6 interviews (snowball method) were conducted, which already showed that the sample had been saturated. In order to be involved, the involved informants were required to provide supervisory services in the field of social work and to have at least one year of experience. The interviews were recorded on a dictaphone, from which a verbatim transcript was made. I subsequently coded the transcripts transcribed in this way (processed by the cluster method). Within the first area, i.e., identification, there were identified these clusters: the humanities direction of education, supervision training, psychotherapeutic training and preparation for limits. Within the second area, i.e., the formal requirements of supervision, the following clusters can be specified: contracting, formal limits, content limits, supervisor under supervision. In the area of supervision, which was identified as the third area, I present the following identified clusters: self-reflection, naming limits and ethical aspects. The last, fourth area, i.e., the benefits of supervision, brought the following clusters: personal development, re-contracting, emotional intelligence. The results of the thesis can be used in the training of supervisors, or for the development of already qualified supervisors in practice.

Limits of Drawings
Korejsová, Karolina ; Pfeiffer, Jan (advisor) ; Francová, Sylva (referee)
In my bachelor thesis I research the topic of drawing and its variation and transformation throughout time and genre. I will describe the boundaries that define it and how these boundaries expand. I will focus on the difference between its significance and visuality in historical context and relate its variability to contemporary experimental trends. I will present drawing in a broad historical, cultural and technical context and this complete the image of its current boundaries. For the practical part, I am inspiration from said variability of drawing and its experimental forms. This work should correspond to the transformation mentioned in the didactic part of the thesis. An installation of a spatial drawing was created. In the didactic part, I elaborate on the section regarding the transformation of drawing into non-traditional forms and describe how such drawing experiments could be incorporated into practical education.
