Development of thermal insulating materials based on waste textile fibers
Přikrylová, Pavlína ; Peterková, Jitka (referee) ; Zach, Jiří (advisor)
The increasing quantity of waste represents serious environmental, social and economic problem. Wastes produced from industry and households. A large part of the economy transforms a certain amount of raw materials to waste in their production, because it is currently emphasis is placed on finding sustainable sources of raw materials. One of the suitable secondary raw materials can be discarded textiles or waste from the textile industry. These kinds of textile waste often ends up in landfills or incinerators, so it is from an ecological and environmentally advantageous to their further use. The diploma thesis deals with the study and development of thermal and acoustic insulation materials based on textile fibers. It focuses on the legislative requirements for waste management for the sorting of textile wastes and their subsequent modification before reuse. Further it contains kinds of textile fibers and bonding technologies thermal and acoustic insulation materials. Finally, an evaluation of thermal insulation, acoustic and mechanical properties of fibrous insulation materials.

Controversial development of social policy in the field of health care in social services
Soudská, Kristýna ; Háva, Petr (advisor) ; Bodnár, Jan (referee)
This dissertation focuses on the long term (2006 - 2015) unsolved problems with the critical nature of healthcare payments in residential social services (PZSS) in the Czech Republic. The aim is a critical reflection of the legitimacy and the causes of this condition, including past efforts to identify and solutions. The used research methods are institutional analysis in combination with critical discourse analysis. The work is conceived as a critically-oriented research on social and health policies in the field of health care financing in PZSS in the period 1998 - 2015. Main findings of the cause of this problem are the failure to use the tool health- insurance plans and their unjustifiable replacement tool called. Reimbursement regulations, the use of which in combination with by power unilateral approach in the contractual relationship between health insurance and PZSS not only leads to problems, but especially to the general alienation public health insurance from the objectives and functions of the health system itself, which provides in this case health care in PZSS.

HDR Image Artifact Compensation
Müllerová, Věra ; Zemčík, Pavel (referee) ; Musil, Martin (advisor)
Tato diplomová práce se zabývá syntézou HDR obrazu (High Dynamic Range Imaging). HDRI technologie se stala v posledních letech velice populární. Běžný a nejvíce používaný způsob vytvoření HDR obrazu je spojení více snímků stejné scény pořízených pomocí různých expozičních časů. Tato technika funguje správně pouze v případě, že se jedná o statickou scénu. Pokud je však ve scéně nějaký pohyb ve chvíli, kdy se pořizují snímky dané scény, výsledný HDR obraz obsahuje artefakty zvané jako duchy. V této práci jsou prezentovány základní informace o HDRI se zaměřením na metody odstraňující artefakty z HDR obrazů. Práce shrnuje již existující metody a dvě z nich - tzv. bitmap movement detection a histogram based ghost detection - představuje jako vhodné pro použití v real-time skládání HDR obrazu a pro implementaci na FPGA (Field-Programmable Gate Array) architektuře. Tyto metody jsou v práci implementovány v programovacím jazyce C++ jako prototypy. Navíc je zde navržena modifikace metody založené na výpočtu histogramu pro jednodušší a efektivnější implementaci na FPGA architektuře.

Construction of intencionality by adolescent deliquents
Onder, Jakub ; Smetáčková, Irena (advisor) ; Chrz, Vladimír (referee)
In this paper I will be mapping so-called intentional profile of juvenile delinquents. This is way of their perception and experience of surrounding world, how they apply significance and how they think about it. Part of this profile is idea of role and participation within the frame of this world. Next goal of this research is explanation of delinquent behavior as part of intentional profile. Research took place in youth detention center. It consisted of narrative and discourse analysis of four fifty minute long autobiographic interviews with four boys sixteen or seventeen years old with delinquent past. In interviews was emphasized independent selection of subject by respondents themselves. Result of analysis was formation of so-called theory of egocentrism. This theory has been compared with other theories and research and embodied in context of social sciences in second part of this paper. Egocentrism is compared with splitting defense mechanism according to M. Klein. In conclusion of this paper were formulated psychotherapeutic recommendations for employees of youth detention centers for work with juvenile delinquents based on findings of performed research.

Optimizing Flow and Segregaton Properties of Lactose/Microcrystalline Cellulose Mixture for Tablet Compression.
Zámostný, P. ; Kreibichová, B. ; Hofmanová, D. ; Kulaviak, Lukáš ; Zelenková, K. ; Růžička, Marek
The present study deals with optimizing the flow and segregation properties of levocetirizine hydrochloride formulation, where the delay between homogenization and tablet compression was found to affect the tablet content uniformity. In addition to API, the base formulation comprised spray dried lactose monohydrate, milled lactose monohydrate 200 mesh, Avicel PH 101 microcrystalline cellulose, and minor excipients. Several alternative mixtures were prepared using the same total composition, but different grades of lactose and microcrystalline cellulose. These mixtures were then tested for the segregation behavior in an in-house segregation device and the flow properties using the Freeman FT4 powder rheometer. The segregation tests showed the grade of lactose is essential for mixture in-flow segregation. While SD lactose mixtures increased the API content in a direction countercurrent to flow, the milled lactose mixtures segregated API concurrently. Mixtures using both lactose grades showed combined effect, resulting in the least segregation due to the two segregation processes competing with each other. However, the segregation was extremely sensitive to ageing of the mixture. It was also found that each type of lactose causes a different flow regime of the mixture in process vessels. In order to improve the content uniformity of the tablets, it was found the volumetric flow regime of transport to tablet press is required as well as the aggregate formation should be prevented.\n
