On-line nonlinear estimation
Kulhavý, Rudolf
The Bayesian identification of complex models is known to require extensive computer resources. Practical implementation requires approximation of the theoretically optimal solution. The paper discusses three major approaches to approximate Bayesian estimation-local weighting of data, reduction of model family to representative points and minimum relative entropy restoration of the information divergence of the empirical and model distributions of data.

Černý, Martin ; Šlajchrt, Zbyněk (advisor) ; Pecinovský, Rudolf (referee)
The aim of this diploma thesis is to implement a presentation layer for the Reminiscence Computer Therapy application. Reminiscence Therapy involves the discussion of the past memories and it is believed to help people with dementia to improve their well-being and sustain their memories. Computer Reminiscence Therapy involves technology in this therapy. The research introduces into Dementia and Reminiscence Therapy with and without using technologies. The application developed as part of this diploma thesis uses picture upload and speech recognition techniques for the memory input. This is used to support remembering of past memories and to increase discussion. The application can be used with or without the carer as well as with friends and family members. The six most important requirements on the developed application are the speech recognition, picture upload, asking questions about the previous recordings, asking questions about tagged friends, using old stories for discussion and presenting the statistics. The application was developed as a part of the competition made by AngelHack organization. Presentation, business and persistence layers of the application are discussed in this diploma thesis as well as user manual and persistence layer implementation of the requirements. The presentation layer was developed using React framework for JavaScript. Other libraries have to be used as well with the most important being Redux library for storing application state. This library affected the structure of the persistence layer.

Using of the Care benefit by Users of Social services
ŠINÁKLOVÁ, Marie
The bachelor thesis deals with the widespread social benefit, the attendance allowance and problems associated with it, which implies the main objective of this work, to find out how or what for this allowance is used. This thesis consists of a theoretical and a practical part. In the theoretical part I focused mainly on the purpose, the principles and basic functions of the allowance. I have also described who is and who is not entitled to the allowance, and when such entitlement may extinguish. In this part, I also focused on what the allowance is intended for and what it has to be properly utilized for. Furthermore, I mentioned in my thesis the inspection in accordance with the Social Services Act and the means of protection applied by the state in order to prevent the abuse of the allowance. In the theoretical part, I also mentioned the history of this allowance when it still was an allowance for attending a close person. Due to the fact that the attendance allowance is intended for people who are disadvantaged in some way, I also put a chapter on disability into the theoretical part, where I gave a definition of disability, its types and forms or for example specific needs that result from such disability. In the second, practical part, the qualitative research method was applied. Data collection was conducted by questioning using the technique of a semi-controlled interview. Interviews were conducted with six communication partners that I have selected using the "snowball" method, so called accretion. The aim of this thesis was mainly to determine how or what for the attendance allowance is used by ist beneficiaries. Whether the amount of the attendance allowance is sufficient for its users to cover the costs of providing the social service. Whether users because of the low value of the attendance will be required to limit their individual needs and interests in some way. Whether users have identified some changes after the amendment of the Social Services Act. For the above objectives I tried to get the answers needed to solve the respective issue.

Modelling, parameter estimation, optimisation and control of transport and reaction processes in bioreactors.
ŠTUMBAUER, Václav
With the significant potential of microalgae as a major biofuel source of the future, a considerable scientific attention is attracted towards the field of biotechnology and bioprocess engineering. Nevertheless the current photobioreactor (PBR) design methods are still too empirical. With this work I would like to promote the idea of designing a production system, such as a PBR, completely \emph{in silico}, thus allowing for the in silico optimization and optimal control determination. The thesis deals with the PBR modeling and simulation. It addresses two crucial issues in the current state-of-the-art PBR modeling. The first issue relevant to the deficiency of the currently available models - the incorrect or insufficient treatment of either the transport process modeling, the reaction modeling or the coupling between these two models. A correct treatment of both the transport and the reaction phenomena is proposed in the thesis - in the form of a unified modeling framework consisting of three interconnected parts - (i) the state system, (ii) the fluid-dynamic model and (iii) optimal control determination. The proposed model structure allows prediction of the PBR performance with respect to the modelled PBR size, geometry, operating conditions or a particular microalgae strain. The proposed unified modeling approach is applied to the case of the Couette-Taylor photobioreactor (CTBR) where it is used for the optimal control solution. The PBR represents a complex multiscale problem and especially in the case of the production scale systems, the associated computational costs are paramount. This is the second crucial issue addressed in the thesis. With respect to the computational complexity, the fluid dynamics simulation is the most costly part of the PBR simulation. To model the fluid flow with the classical CFD (Computational Fluid Dynamics) methods inside a production scale PBR leads to an enormous grid size. This usually requires a parallel implementation of the solver but in the parallelization of the classical methods lies another relevant issue - that of the amount of data the individual nodes must interchange with each other. The thesis addresses the performance relevant issues by proposing and evaluation alternative approaches to the fluid flow simulation. These approaches are more suitable to the parallel implementation than the classical methods because of their rather local character in comparison to the classical methods - namely the Lattice Boltzmann Method (LBM) for fluid flow, which is the primary focus of the thesis in this regard and alternatively also the discrete random walk based method (DRW). As the outcome of the thesis I have developed and validated a new Lagrangian general modeling approach to the transport and reaction processes in PBR - a framework based on the Lattice Boltzmann method (LBM) and the model of the Photosynthetic Factory (PSF) that models correctly the transport and reaction processes and their coupling. Further I have implemented a software prototype based on the proposed modeling approach and validated this prototype on the case of the Coutte-Taylor PBR. I have also demonstrated that the modeling approach has a significant potential from the computational costs point of view by implementing and validating the software prototype on the parallel architecture of CUDA (Compute Unified Device Architecture). The current parallel implementation is approximately 20 times faster than the unparallized one and decreases thus significantly the iteration cycle of the PBR design process.

Burgerová, Michaela ; Gardiánová, Ivana (advisor) ; Jan, Jan (referee)
Genus camel (Camelus) includes two species, the Dromedary camel (Camelus dromedarius) and Bactrian camel (Camelus bactrianus). Camels have a wide range of utilization. People in Arabia countries but also in India and Egypt are using camels as a milk and meat animal, or even as a transport and companion animals and riding animals too. The aim of this thesis was to find sources about camel keeping and using and his role of farm animal in different cultures and countries. And about conditions and requirements in captivity. The first part of thesis contains information about phylogeny and origin of the camel family, taxonomy of camels, short information about the history of domestication and using of camels. There are also described the two species in terms of species biology etc. plus a brief mention of camel hybrids and camel breeds. The second part focuses on the use of camels. The preffered and most common use is in the production of milk, other dairy products from camel milk, fermentation of milk. Another use is for meat performance, meat composition, describes products. His utilization i also useful for other parts such as hair wool and mane, they come mainly from bactrian camel (Camelus bactrianus). The last is working utilization of camels, carrying baggage. Then hobby use. The thesis describes the conditions of keeping camels in captivity, keeping camels in Somalia, requirements for the supply of water and food, housing conditions in the Czech Republic, it is particularly widespread keeping camels in zoos. In Czech Republic they are small private camel breeders. For comparison they are conditions for keeping camels in captivity in Australia.

Puppies and young dogs nutritions
Šabatová, Kateřina ; Hučko, Boris (advisor) ; Plachý, Vladimír (referee)
Puppies and young dogs nutritions Summary In this work I have attempted to summarize the most important aspects in nutrition of puppies and dogs in growth. The introduction describes the digestive tract and also the changes that have occurred due to domestication. Next is explained the importance of nutrition and water in nutritional requirements of a dog. Important are needs of nutrients and energy that are necessary to maintain the provision of the necessary vital functions. The basic components of food are proteins, saccharides, lipids, minerals and vitamins. I explain the necessary proportions, the amounts and the possible consequences of their lack in food. I focus on essential fatty acids, which in recent years are subject to frequent explorations and their pros and cons are not yet fully understood. I also mention ballast and significant specific active substances. Nutrition of pregnant and lactating females is often neglected, but for puppies it is a very crucial period. The influence of nutrition of pregnant females to the size and weight of newborn puppies has been proved. Further I deal with nutrition of puppies immediately after birth, I explain the composition of colostrum and its effect on the immunity system of the puppy. I also compare ratios of nutrients in the colostrum and milk. Further, I deal with the feeding of the individual at the time of weaning and in different growth periods. There are many possibilities of feeding puppies from after weaning until adulthood described in books. With the new knowledge about nutrition the ways of feeding our dogs have inevitably changed , but also the dogs' nutritional requirements have changed due to the conditions where and how they live and what their nutrient needs are according to their sport, breeding or other use. Currently, there is a possibility of a commercially produced complete nutritional diet or home-prepared fresh food - cooked or raw- barf. In the last chapter, I summarized possible aspects of malnutrition and its potential consequences. I described the most common problems associated with inadequate nutrition of growing dogs such as obesity as well as malnutrition, which also adversely affects the individual. The influence of proper nutrition of the puppy on its growth is clear. If we neglect the nutrition of the dog in the first two years of its life, the consequences are often irreversible.

Packet Classification Algorithms
Puš, Viktor ; Lhotka,, Ladislav (referee) ; Dvořák, Václav (advisor)
Tato práce se zabývá klasifikací paketů v počítačových sítích. Klasifikace paketů je klíčovou úlohou mnoha síťových zařízení, především paketových filtrů - firewallů. Práce se tedy týká oblasti počítačové bezpečnosti. Práce je zaměřena na vysokorychlostní sítě s přenosovou rychlostí 100 Gb/s a více. V těchto případech nelze použít pro klasifikaci obecné procesory, které svým výkonem zdaleka nevyhovují požadavkům na rychlost. Proto se využívají specializované technické prostředky, především obvody ASIC a FPGA. Neméně důležitý je také samotný algoritmus klasifikace. Existuje mnoho algoritmů klasifikace paketů předpokládajících hardwarovou implementaci, přesto však tyto přístupy nejsou připraveny pro velmi rychlé sítě. Dizertační práce se proto zabývá návrhem nových algoritmů klasifikace paketů se zaměřením na vysokorychlostní implementaci ve specializovaném hardware. Je navržen algoritmus, který dělí problém klasifikace na jednodušší podproblémy. Prvním krokem je operace vyhledání nejdelšího shodného prefixu, používaná také při směrování paketů v IP sítích. Tato práce předpokládá využití některého existujícího přístupu, neboť již byly prezentovány algoritmy s dostatečnou rychlostí. Následujícím krokem je mapování nalezených prefixů na číslo pravidla. V této části práce přináší vylepšení využitím na míru vytvořené hashovací funkce. Díky použití hashovací funkce lze mapování provést v konstantním čase a využít při tom pouze jednu paměť s úzkým datovým rozhraním. Rychlost tohoto algoritmu lze určit analyticky a nezávisí na počtu pravidel ani na charakteru síťového provozu. S využitím dostupných součástek lze dosáhnout propustnosti 266 milionů paketů za sekundu. Následující tři algoritmy uvedené v této práci snižují paměťové nároky prvního algoritmu, aniž by ovlivňovaly rychlost. Druhý algoritmus snižuje velikost paměti o 11 % až 96 % v závislosti na sadě pravidel. Nevýhodu nízké stability odstraňuje třetí algoritmus, který v porovnání s prvním zmenšuje paměťové nároky o 31 % až 84 %. Čtvrtý algoritmus kombinuje třetí algoritmus se starším přístupem a díky využití několika technik zmenšuje paměťové nároky o 73 % až 99 %.

Location-aware data transfers scheduling for distributed virtual walkthrough applications.
Přibyl, Jaroslav ; Sochor, Jiří (referee) ; Sojka, Eduard (referee) ; Zemčík, Pavel (advisor)
Důležitou součástí aplikací procházení distribuovanou virtuální scénou je proces plánování přenosu dat. Jeho hlavním úkolem je zajištění efektivního přenosu dat a maximální kvality renderovaného obrazu. Největší vliv na kvalitu renderované scény mají omezení síťového připojení. Tyto omezení lze redukovat pomocí multi-resolution reprezentace dat scény, určováním priorit stahování jednotlivých částí scény, a přednačítáním dat. Pokročilé metody pro určování priorit a přednačítání částí scény jsou založeny na predikci pohybu uživatele vycházející z matematického popisu jeho pohybu. Tyto metody jsou schopny predikovat následující pozici uživatele jen v krátké vzdálenosti od jeho aktuální polohy. V případě náhlých, ale pravidelných změn směru pohybu uživatele jsou tyto metody nedostatečné co do přesnosti i délky predikce. V této práci je navrhnut komplexní přístup k řešení plánování přenosu dat splňující i tyto požadavky. Navrhované řešení využívá predikci pohybu uživatele založenou na znalostech k určení priority stahování dat i předstahování částí scény. Provedené experimenty nad testovacími daty ukazují, že navržené schéma plánování přenosu dat umožňuje dosažení vyšší efektivity přenosu dat a vyšší kvality renderovaného obrazu během průchodu testovací scénou.

OPTIMIZATION OF ALGORITHMS AND DATA STRUCTURES FOR REGULAR EXPRESSION MATCHING USING FPGA TECHNOLOGY
Kaštil, Jan ; Plíva, Zdeněk (referee) ; Vlček, Karel (referee) ; Kotásek, Zdeněk (advisor)
Disertační práce se zabývá rychlým vyhledáváním regulárních výrazů v síťovém provozu s použitím technologie FPGA. Vyhledávání regulárních výrazů v síťovém provozu je výpočetně náročnou operací využívanou převážně v oblasti síťové bezpečnosti a v oblasti monitorování provozu vysokorychlostních počítačových sítí. Současná řešení neumožňují dosáhnout požadovaných multigigabitových propustností při dodržení všech požadavků, které jsou na vyhledávací jednotky kladeny. Nejvyšších propustností dosahují implementace založené na využití inovativních hardwarových architektur implementovaných v FPGA případně v ASIC. Tato disertační práce popisuje nové architektury vyhledávací jednotky, které jsou vhodné pro implementaci jak v FPGA tak v ASIC. Základní myšlenkou navržených architektur je využití perfektní hashovací funkce pro implementaci přechodové tabulky konečného automatu. Dále byla navržena architektura, která umožňuje uživateli zanést malou pravděpodobnost chyby při vyhledávání a tím snížit paměťové nároky vyhledávací jednotky. Disertační práce analyzuje vliv pravděpodobnosti této chyby na celkovou spolehlivost systému a srovnává ji s řešením používaným v současnosti. V rámci disertační práce byla provedena měření vlastností regulárních výrazů používaných při analýze provozu moderních počítačových sítí. Z provedené analýzy vyplývá, že velká část regulárních výrazů je vhodná pro implementaci pomocí navržených architektur. Pro dosažení vysoké propustnosti vyhledávací jednotky práce navrhuje nový algoritmus transformace abecedy, který umožňuje, aby vyhledávací jednotka zpracovala více znaků v jednom kroku. Na rozdíl od současných metod, navržený algoritmus umožňuje konstrukci automatu zpracovávajícího libovolný počet symbolů v jednom taktu. Implementované architektury dosahují v porovnání se současnými metodami úspory paměti zlepšení až 200MB.

Standardization of nursing care as an integral part of preparation for the accreditation survey
ŠIMÁČKOVÁ, Alexandra
The Diploma thesis deals with standardisation of nursing care in the context of preparatory work for accreditation survey, i.e. a mutual harmony between standards developed in health care institutions and those developed by the SAK ČR accreditation commission. Standardisation is a process of setting essential rules which should guarantee providing a high quality nursing care. These rules (standards) enable to evaluate the quality of all nursing activities. Nurses should be aware of standardisation process and be actively engaged in it. The theoretical part describes the part of Czech nursing system concept focused on the quality of nursing care, defines the quality itself, maps the systems which help improve the quality of nursing care in health care institutions and refers to the formation of nursing standards. Practical part deals with five aims stated at the beginning: To map the quality of standardisation in nursing care as a preparatory part of accreditation survey. To find out if nursing care in hospitals is carried out through the method of nursing process. To find out if nursing care is supported by properly kept documentation. To find out if the needs of education were considered for all patients. To find out if nurses are aware of the importance of nursing care standardisation. We chose a quantitative research method. To collect the research data we used anonymous questionnaires. Each of the hospitals was given 50 questionnaires, i.e. 250 in total as the research group was made by respondents from the hospitals in Jindřichův Hradec, Pelhřimov, Tábor, Písek a Havlíčkův Brod. 230 completed questionnaires were returned and 204 of them represented then the research group. Within the research, we accomplished the aims stated, and proved these hypotheses: Hypothesis 1 (H1): The hospitals meet all requirements of accreditation survey of nursing care standardisation. H2: Nursing care in the hospitals is carried out through the method of nursing process. H3: Nursing care in the hospitals is supported by properly kept documentation. H4: The needs of education were considered for all patients and recorded in the nursing documentation. H5: The nurses are aware of the importance of nursing care standardisation. The quantitative research resulted into the statement that all hospitals meet the requirements of accreditation survey of nursing care standardisation. Nursing care in the hospitals is carried out through the method of nursing process which is properly recorded in nursing documentation. It was also found out that the needs of education were considered for all patients and properly recorded in the nursing documentation. The nurses are aware of the importance of nursing care standardisation. The facts resulted from the research prove that the quality of nursing care in the chosen hospitals is very high and meets the requirements of accreditation standards. The research findings will be offered to the hospital managements as an educational material for nurses and midwives.
