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.

Network Architecture and Interconnection of Embedded Systems
Trchalík, Roman ; Drábek, Vladimír (referee) ; Srovnal, Vilém (referee) ; Švéda, Miroslav (advisor)
The thesis focuses on the architecture of embedded systems. It summarizes the current state of accepted standards from IEEE 1451 family, which deals with creating an environment for the sensors and their involvement in various networks. These standards describe the open, network-independent communication architecture for a sensor-based system. One of the main outcomes of this work is the architectures presented as case studies, which can be used as design patters for embedded applications. They are demonstrated on ZigBee technology suitable mainly for small devices with very low power consumption. Based on these studies the new design of universal gateway was proposed. Its major advantage is that it allows interconnection of the endpoints based on different sensor network technologies. Additionally, the thesis deals with modifying the routing protocol of ZigBee network in order to reduce power consumption required to transmit one data packet.

Právní a zdravotně sociální aspekty činnosti OSPOD jako ustanovených opatrovníků v zámu nezletilých dětí
BORSKÁ, Jana
The Czech Republic as a signatory of the Convention on the Rights of the Child has vested the practice of state administration in the field of care for minor children to municipalities with extended powers, where the protection of the rights and legitimate interests of minor children is safeguarded by state authorities of social and legal protection of children (ASLPC hereinafter). These authorities are incorporated to the extent laid down by the Act on Social and Legal Protection of Children (Act No 359/1999 Coll., as amended). The position and roles of ASLPC and their competence and jurisdiction are also regulated by the same act. The position of workers of these authorities and its legal embodiment is equally important. Regarding professionality, there are high demands on these workers. In the Czech Republic, significant changes in legislature have been made over the past three years. These amendments have led to the strengthening of the rights of minor children and to the establishing of new tools for their protection. In connection with the adoption of new substantive regulation of family law, which is now exhaustively dealt with by the Act No 89/2012 Coll., the Civil Code, new procedural rules have been established regarding protection of rights of minor children. Such procedural legislation includes (apart from the long-existent Act No. 99/1963, the Code of Civil Procedure) the Act No 292/2013 Coll., on Special Civil Proceedings. The decision-making regarding minor children has been vested mainly by the state into the competence of courts. The courts appoint the locally relevant ASLPC as a guardian who then represents the interests of minor children. The purpose, interwoven with and derived from the first one, was to explore the opinions of selected social workers of ASLPC and of district court judges regarding the defined problems occurring during the work of ASLPCs and courts while protecting the interests of minor children. These particularly include: the use of the tool of precautionary measure; problems of different territorial jurisdiction of courts and ASLPCs; processing of complaints regarding bias in various phases of the proceedings; professional training of workers of ASLPC It is evident from the proposals of both judges and ASLPC workers that it is necessary to unify territorial jurisdiction. The courts are suggesting the priority criterion of the address where the child mainly resides. ASLPC workers suggest the official permanent residence as the prime criterion. Bias causes problems in all phases of proceedings. It is obvious that courts take differing approaches towards the solution of this problem (some courts solve the problem of bias complaints filed by the parties while other courts do not) and for ASLPC workers it is difficult to assess how to act when such complaint is raised against them. The training of ASLPC workers - workers are obliged to educate themselves and their employer is obliged to finance such training. Not all ASLPCs are able to provide training in the required extent - due to financial reasons (the average costs of education of one employee pose from 9,169 to 13,400 CZK annually and they cover approximately 6 days of training). The heavy work-load caused by insufficient numbers of ASLPC employees prevents them from completing such compulsory training. As part of the examination of the "participation of a collision guardian in court proceedings" it has been found out that irregular participation of the worker in the proceedings (absence from participation in appeals proceedings); incomplete reports (directed to courts) from surveys in families. Based on comprehensive examination of the problems of territorial jurisdiction, it was recommended that requests are independently recorded and financial compensation is provided for ASLPCs who are requested to represent minors in front of courts, to draft proposals for precautionary measures.

Selection of the optimal financing housing for selected client
HOLÝ, Hubert
At the beginning of the thesis I am focused on gathering information on mortgage loans in the current financial market. At the beginning of the chapter on mortgage credit, I will discuss dividing the mortgage loans. I draw up a detailed procedure that has everything a client to do to get a loan, what are the procedures in banks and what banks need to know information about the client. The next chapter will bring information on building savings and conditions, which the client must satisfy in order to get a loan from the savings. Also characteristic of this product. In the last chapter of the theoretical part of the introductory acquainted readers with investments in mutual funds and bring their individual characteristics and procedures for negotiation. In the practical part will deal has particular offering selected companies, which will be compared using the methods of multi-criteria decision. The work is divided on the analysis of mortgage loans, building savings and investment products. Information from these analyzes will also be used for application to a specific customer with specific requirements for housing. From the client I find out any information about his wishes and requirements for their future with regards to housing. The client chooses the aspects that are most important for him and the order in which they should be respected. It is for this reason that it is often not important final amount that the client pays for the loan, but for him the current situation in life more important monthly installment. Finally, the client selected the optimal variant, as can finance their own housing.

International Digital Library of Manuscripts
Knoll, Adolf,
The Manuscriptorium Digital Library is Europe’s largest digital library of manuscripts providing access to data from more than 120 institutions across Europe incl. ca. 55 most important Czech collections. In March 2015, it contained 43,372 fully digitized documents and more than 337,000 bibliographic records. The documents are not only of European origin (Western, Slavonic, Hebrew, Armenian ...), but there are also data representing Arabic, Persian, Ottoman, Indian and other manuscript traditions. The digital library was launched in 2003 by the National Library of the Czech Republic, in partnership with the Czech AiP Beroun Company. In comparison and in contrast with other aggregation services, it provides seamless access to full digital documents on the fly, reusing thus repositories of partner digital libraries. Users do not need to travel or to navigate from one physical place or digital library to another one to access needed documents. Manuscriptorium provides uniform interface to any data from any digital library that signed the partnership agreement. The internal metadata solution is based on the robust TEI P5 approach and suits both library and researchers’ requirements for description and structuring. It aggregates not only fully digitized documents, but also the partially digitized ones and bibliographic records. It contains manuscripts as well as old printed books, historical maps, and historical posters. The documents are mostly represented by digital images and in certain extent also by full texts, TEI-structured and unstructured. The Manuscriptorium larger environment provides also online support to TEI authoring and online metadata validation and upload. ...

: Time Requirement for Basic Nursing Care Procedures
SOUMAROVÁ, Iveta
A large number of nursing procedures are carried out in each ward in every hospital every day. In its theoretical part, this Bachelor thesis presents twenty basic procedures. The goal of the thesis was to find out what the most used nursing procedures are and to map the time consumption for individual nursing procedures. The quantitative research method was applied in the Bachelor thesis. Data were collected by measurement of time consumption of ten individual nursing procedures. These ten procedures were selected from a list of most used nursing procedures. Performance of the procedures was observed at the internal and surgical wards of the Hospital in České Budějovice. Both wards were observed over a 3-day span. Ten most often used nursing procedures were selected from the total number of procedures identical for both wards. Correctness of inclusion of the procedures was evaluated by the chi quadrat test in a contingency table. In addition, each of the ten most used procedures was measured ten times at each ward, from the preparation to the clean-up of instruments. The individual time values were averaged and presented along with conclusive deviations. A conformity with or difference in the time consumed was tested statistically by using the F or T test, where the applied significance level equals 5%. The research group was composed of the nurses and ancillary nursing personnel. Results are presented in graphs and tables. The following procedures differed in the individual wards: administration of medicines per os, serving of meals, venous blood sampling and blood pressure measurement. The bachelor thesis is focused on the time consumption for individual nursing procedures. The time consumption and the frequency of the individual procedures can serve as a base of explanation of the number of employees to the nursing management.
