Acceleration Methods for Evolutionary Design of Digital Circuits
Vašíček, Zdeněk ; Miller, Julian (referee) ; Zelinka,, Ivan (referee) ; Sekanina, Lukáš (advisor)
Ačkoliv můžeme v literatuře nalézt řadu příkladů prezentujících evoluční návrh jakožto zajímavou a slibnou alternativu k tradičním návrhovým technikám používaným v oblasti číslicových obvodů, praktické nasazení je často problematické zejména v důsledku tzv. problému škálovatelnosti, který se projevuje např. tak, že evoluční algoritmus je schopen poskytovat uspokojivé výsledky pouze pro malé instance řešeného problému. Vážný problém představuje tzv. problém škálovatelnosti evaluace fitness funkce, který je markantní zejména v oblasti syntézy kombinačních obvodů, kde doba potřebná pro ohodnocení kandidátního řešení typicky roste exponenciálně se zvyšujícím se počtem primárních vstupů. Tato disertační práce se zabývá návrhem několika metod umožňujících redukovat problem škálovatelnosti evaluace v oblasti evolučního návrhu a optimalizace číslicových systémů. Cílem je pomocí několika případových studií ukázat, že s využitím vhodných akceleračních technik jsou evoluční techniky schopny automaticky navrhovat inovativní/kompetitivní řešení praktických problémů. Aby bylo možné redukovat problém škálovatelnosti v oblasti evolučního návrhu číslicových filtrů, byl navržen doménově specifický akcelerátor na bázi FPGA. Tato problematika reprezentuje případ, kdy je nutné ohodnotit velké množství trénovacích dat a současně provést mnoho generací. Pomocí navrženého akcelerátoru se podařilo objevit efektivní implementace různých nelineárních obrazových filtrů. S využitím evolučně navržených filtrů byl vytvořen robustní nelineární filtr implusního šumu, který je chráněn užitným vzorem. Navržený filtr vykazuje v porovnání s konvenčními řešeními vysokou kvalitu filtrace a nízkou implementační cenu. Spojením evolučního návrhu a technik známých z oblasti formální verifikace se podařilo vytvořit systém umožňující výrazně redukovat problém škálovatelnosti evoluční syntézy kombinačních obvodů na úrovni hradel. Navržená metoda dovoluje produkovat komplexní a přesto kvalitní řešení, která jsou schopna konkurovat komerčním nástrojům pro logickou syntézu. Navržený algoritmus byl experimentálně ověřen na sadě několika benchmarkových obvodů včetně tzv. obtížně syntetizovatelných obvodů, kde dosahoval v průměru o 25% lepších výsledků než dostupné akademické i komerční nástroje. Poslední doménou, kterou se práce zabývá, je akcelerace evolučního návrhu lineárních systémů. Na příkladu evolučního návrhu násobiček s vícenásobnými konstantními koeficienty bylo ukázáno, že čas potřebný k evaluaci kandidátního řešení lze výrazně redukovat (defacto na ohodocení jediného testovacího vektoru), je-li brán v potaz charakter řešeného problému (v tomto případě linearita).

Vektorová segmentace objemových medicínských dat založená na Delaunay triangulaci
Španěl, Michal ; Martišek, Dalibor (referee) ; Sochor, Jiří (referee) ; Kršek, Přemysl (advisor)
Image segmentation plays an important role in medical image analysis. Many segmentation algorithms exist. Most of them produce data which are more or less not suitable for further surface extraction and anatomical modeling of human tissues. In this thesis, a novel segmentation technique based on the 3D Delaunay triangulation is proposed. A modified variational tetrahedral meshing approach is used to adapt a tetrahedral mesh to the underlying CT volumetric data, so that image edges are well approximated in the mesh. In order to classify tetrahedra into regions/tissues whose characteristics are similar, three different clustering schemes are presented. Finally, several methods for improving quality of the mesh and its adaptation to the image structure are also discussed.

Multimedia Data Processing in Heterogeneous Distributed Environment
Kajan, Rudolf ; Ferko,, Andrej (referee) ; Míkovec, Zdeněk (referee) ; Herout, Adam (advisor)
Pervasive computing sa zameriava odstránenie zložitostí pri interakcii s výpočtovou technikou a zvýšenie efektivity pri jej každodennom používaní. Ale i po viac ako 15 rokoch od sformulovania hlavných cieľov Pervasive computingu existujú aspekty interakcie ktoré stále nie sú súčasťou užívateľskej skúsenosti s dnešnou technológiou. Bezproblémová integrácia s prostredím vedúca k technologickej neviditeľnosti, alebo interakcia naprieč rôznymi zariadeniami predstavujú stále veľkú výzvu. Hlavným cieľom tejto práce je prispieť k tomu, aby sa ciele Pervasive computingu priblížili k realizovaniu tým, že predstavíme spôsob intuitívneho zdieľania informácií medzi osobným a verejne umiestneným zariadením. Predstavili sme tri interakčné techniky, ktoré podporujú intuitívnu výmenu obsahu medzi osobným zariadením a zdieľaným displejom. Tieto techniky sú založené na prenose videa, rozšírenej realite a analýze pohľadových dát. Okrem interakčných techník sme tiež predstavili mechanizmus pre získavanie, prenos a rekonštrukciu aplikačného stavu na cieľovom zariadení.

Methodology of highly reliable systems design
Straka, Martin ; Gramatová, Elena (referee) ; Racek, Stanislav (referee) ; Kotásek, Zdeněk (advisor)
In the thesis, a methodology alternative to existing methods of digital systems design with increased dependability implemented into FPGA is presented, new features which can be used in the implementation and testing of these systems are demonstrated. The research is based on the use of FPGA partial dynamic reconfiguration for the design of fault tolerant systems. In these applications, the partial dynamic reconfiguration can be used as a mechanism to correct the fault and recover the system after the fault occurrence. First, the general principles of diagnostics, testing and digital systems dependability are presented including a brief description of FPGA components and their architectures. Next, a survey of currently used methods and techniques used for the design and implementation of fault tolerant systems into FPGA is described, especially the methods used for fault detection and localization, their correction, together with the principles of evaluating fault tolerant systems design quality. The most important part of the thesis is seen in the description of the design methodology, implementation and testing of fault tolerant systems implemented into FPGAs which uses SRAMs as the configuration memory. First, the methodology of developing and automated checker components design for digital systems and communication protocols is presented. Then, a reference architecture of a dependable system implemented into FPGA is demonstrated including several fault tolerant architectures based on the use of partial dynamic reconfiguration as the mechanism of fault correction and the recovery from it. The principles of controlling the reconfiguration process are described together with the description of the test platform which allows to test and verify the design of fault tolerant systems based on the methodology presented in the thesis. The experimental results and the contribution of the thesis are discussed in the conclusions.

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.

General Data Protection Regulation and its Impact on Grey Literature
Koščík, Michal
In April 2016, the European commission adopted a new General Data Protection Regulation. This regulation is based on fundamental principles of the existing legislation and elaborates it further into the set of rather detailed legal instructions. The suggested paper aims to summarize the parts of the new regulation that are most relevant for operators of gray literature repositories, who will have to adapt within the next two years. The paper will focus on the issues of consent to the processing of personal data, the legal regime of processing personal data without the consent of the data subjects, the data subject’s right to information as well as the legal regime of acquisition of personal data by third parties and exercise of the newly formulated right to be forgotten.

Plural Forms of Nouns in Contemporary Spanish
Hrabětová, Michaela ; Čermák, Petr (advisor) ; Zavadil, Bohumil (referee)
- NOUN PLURAL FORMS IN CONTEMPORARY SPANISH The topic of this work, as the title indicates, is the formation of plural of nouns in contemporary Spanish. The treatise is divided into two major parts: theoretical and practical. In the theoretical part, there is a description of the grammatical number as a grammatical category of nouns, later compared with grammatical gender. Afterwards, there is a short summary of the evolution of plural morpheme from ancient Latin to contemporary Spanish. Spanish nouns are divided into several categories according to the affects the plural form has on their meaning. A substantial part of the presented essay deals with the formal expression of plural in Spanish, meaning a description of the plural morphemes which exist in Spanish. There are specified fundamental principles regarding the formation of plural in Spanish. It is conditioned especially by the origin of the noun itself, by the features of the last letter and by several other aspects. Spanish nouns are divided into several groups with the overall objective of better comprehension. First group is formed by nouns assimilated into the Spanish morphological and phonological system, they are subsequently divided depending on their last letter. Second group comprises nouns originally from Latin, French or English...

Historical development of nephrology nursing practice and the need of standards in this field
KESZIOVÁ, Andrea
Nursing care in nephrology brings certain specifics both for the patient and for the nursing staff concerned. For each member of a nephrology multidisciplinary team that participates in identification and meeting bio-psycho-social and spiritual needs of dialysed patients, the quality nursing care provision and the patients´ safety assuring should be the rule. To assure quality care provision in a health care facility, it is necessary to define the professional level of quality, i.e. to introduce processual nursing standards at the national level for all dialysis centers. The objective of this thesis was to make a survey of historical milestones in the development of nephrology nursing in the Czech Republic (in the former Czechoslovakia), from its beginning to present days. In individual parts of the theoretical section various contexts of nursing issues (historical, legal, social, relational, educational) and their interaction are described. The thesis also is focused on detection the importance of aspects influencing the quality of provided nursing care in nephrology and realization of analysis the use and compliance with the existing local nursing standards in individual dialysis centers in the Czech Republic. Another objectives of this thesis were detection of satisfaction rate with existing national standards for nephrology nursing care and to make up a proposal of a national processual standard of nursing care provided to adult dialysed patients. To obtain data the mixed methods research was used. The practical part offers, through conclusions of the quantitative research, explanations of many facts by confirmation or refutation of hypotheses arisen from the qualitative research. The nursing research was conducted through a questionnaire survey in dialysis centers in the Czech Republic. The respondents were head nurses - nursing care managers working in these units. Interviews with representatives of the biggest professional organization of nurses {--} the Czech Nurses Association were also carried out as another research procedure. The survey outcomes have clearly demonstrated the need to introduce national processual standards of nursing care in nephrology practice. Description of the present state is the first step for its improvement. The way out from the current situation is the development of general national processual standards for individual areas of care for nephrology patients and subsequent introduction of them into clinical practice in all dialysis centers in the Czech Republic. One of the components of the thesis is a proposal of the national processual standard of nursing care for a dialysed patient with acute or permanent central venous catheter (CVC). This standard could serve as a model for the development of other national standards of nursing care in nephrology.

Sepsis in intensive care, precautionary measures on the part of nursing personnel and department management
JANOUŠKOVÁ, Ludmila
Sepsis represents a serious medical, but also social problem. Hundreds of thousands of patients die from serious sepsis and septic shock every year. Patients with serious sepsis are treated at intensive care units and their treatment is long, costly and low efficient. These are the reasons why prevention of sepsis focused on prevention and effective treatment of nosocomial infections or timely solution of another problem, e.g. a shock is so much stressed. Nosocomial infections affect about 30 per cent of patients at intensive care units and may cause serious diseases, sepsis or even death. This thesis deals with the possibilities nurses have to influence sepsis, particularly by adherence to aseptic procedures and prevention of nosocomial infection, which might consequently develop in nosocomial sepsis. Combination of quantitative and qualitative methods was used for the research. There were two goals set for the quantitative research. 1. To find whether obstacles occur in adherence to proper aseptic procedures in nursing work as prevention of nosocomial infection occurrence and subsequent septic conditions in patients hospitalized at intensive medicine workplaces. 2. To map the weak points in adherence to proper aseptic procedures in nursing work in intensive care. The goals led to hypotheses H1 Obstacles obstructing thorough adherence to proper aseptic procedures in nursing work exist in intensive care. H2 Non-adherence to aseptic procedures occurs in nursing work at intensive medicine workplaces as a consequence of lack of time for particular interventions. The research sample consisted of nurses from the intensive care workplaces ARD and ICU from 8 hospitals. Questioning method through the questionnaire technique was used for data collection. 342 questionnaires were distributed in total. Hypothesis 1 was refuted, hypothesis 2 was refuted. We found that no obstacles obstructing adherence to proper aseptic methods occur, we mapped the weak points in adherence to proper aseptic procedures in nursing work in intensive care. There were two goals set for the qualitative research. GOAL 3 To find what measures preventing occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces are taken by department managements. GOAL 4 To find out how department management deals with possible occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces. The following research questions were set. 1. What are the measures preventing occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces taken by department managements? 2. How does department management solve possible occurrence of nosocomial infection and subsequent septic conditions in patients hospitalized at intensive medicine workplaces? The research sample consisted of 5 departmental nurses and 5 head nurses from intensive care workplaces from the same hospitals where the quantitative research took place. The research was performed by semi-standardized interview. The research questions were answered. A manual for nurses called ?Recommendation for nurses in prevention of nosocomial infection and nosocomial sepsis not only at intensive care units? was elaborated upon study of these issues and the performed research. A thought map for department management illustrating prevention and solution of nosocomial infection and nosocomial sepsis was also elaborated. Both the document and the research results will be provided particularly to the managements of the hospitals that took part in our research. The thesis may also be helpful to nurses, students and other interested people to gain overall insight into the issue.
