Acceleration of Object Detection Using Classifiers
Juránek, Roman ; Kälviäinen, Heikki (referee) ; Sojka, Eduard (referee) ; Zemčík, Pavel (advisor)
Detekce objektů v počítačovém vidění je složítá úloha. Velmi populární a rozšířená metoda pro detekci je využití statistických klasifikátorů a skenovacích oken. Pro učení kalsifikátorů se často používá algoritmus AdaBoost (nebo jeho modifikace), protože dosahuje vysoké úspěšnosti detekce, nízkého počtu chybných detekcí a je vhodný pro detekci v reálném čase. Implementaci detekce objektů je možné provést různými způsoby a lze využít vlastnosti konkrétní architektury, pro urychlení detekce. Pro akceleraci je možné využít grafické procesory, vícejádrové architektury, SIMD instrukce, nebo programovatelný hardware. Tato práce představuje metodu optimalizace, která vylepšuje výkon detekce objektů s ohledem na cenovou funkci zadanou uživatelem. Metoda rozděluje předem natrénovaný klasifikátor do několika různých implementací, tak aby celková cena klasifikace byla minimalizována. Metoda je verifikována na základním experimentu, kdy je klasifikátor rozdělen do předzpracovací jednotku v FPGA a do jednotky ve standardním PC.

Security of Biometric Systems
Lodrová, Dana ; Busch, Christoph (referee) ; Provazník, Ivo (referee) ; Drahanský, Martin (advisor)
Hlavním přínosem této práce jsou dva nové přístupy pro zvýšení bezpečnosti biometrických systémů založených na rozpoznávání podle otisků prstů. První přístup je z oblasti testování živosti a znemožňuje použití různých typů falešných otisků prstů a jiných metod oklamání senzoru v průběhu procesu snímání otisků. Tento patentovaný přístup je založen na změně barvy a šířky papilárních linií vlivem přitlačení prstu na skleněný podklad. Výsledná jednotka pro testování živosti může být integrována do optických senzorů. Druhý přístup je z oblasti standardizace a zvyšuje bezpečnost a interoperabilitu procesů extrakce markantů a porovnání. Pro tyto účely jsem vytvořila metodologii, která stanovuje míry sémantické shody pro extraktory markantů otisků prstů. Markanty nalezené testovanými extraktory jsou porovnávány oproti Ground-Truth markantům získaným pomocí shlukování dat poskytnutých daktyloskopickými experty. Tato navrhovaná metodologie je zahrnuta v navrhovaném dodatku k normě ISO/IEC 29109-2 (Amd. 2 WD4).

The development of the crime on credits in the South Bohemia before 2014
BUŠKOVÁ, Tereza
The aim of this study is to analyze the development of committing a credit fraud offence under § 211 of the Act. no. 40/2009 Coll., the Penal Code (particularly the development of this crime and the development of the amount of the damage) and consequent comparing the selected macroeconomic indicators development in the period 2005-2014 in the region of South Bohemia. In this work secondary data analysis methods were used. Statistical data obtained from the South Bohemian branch of the Czech Statistical Office and statistical data from Crime Police of the Czech Republic was used as the source. The data evaluating the amount of detected cases of this crime committed by the offenders in the Region South Bohemia, according to the region where the fraud was commited, was analyzed. The analyzed file was 5,713 offenses and 4,219 offenders. The defined set was divided into seven parts (districts), according to the local jurisdiction of the territorial departments of the Czech Police. The observed data was compared with selected macroeconomic indicators. From the results it can be concluded that the highest rate of loan fraud offence (calculated per 1,000 inhabitants) is in the district Stra-konice. Conversely, the lowest crime in the same period is in the district Jindřichův Hradec. This work also re-vealed that the development of macroeconomic indicators has no effect on the development of this crime. In conclusion, it is recommended to promote economic education at primary and secondary schools, thus improving the financial literacy of the population. Furthermore, we can recommend the consistent use of, the Central Credit Register, which is already available, as well as supporting of changes in the legislation, so that the providers have an obligation to investigate the credit applicants more and make the offenders of this crime discouraged by higher penalties imposed for credit fraud.

VRZALOVÁ, Monika
The diploma thesis deals with problems of depression in older people. Mainly the work is focused on identifying and analyzing the role of nurses in screening for depression in older people in primary care, acute care, long-term care and home care. This thesis was focused on theoretical direction and was used the method of design and demonstration. In this thesis was set one main goals with five research questions. The main goal was to identify and analyze the role of nurses in screening for depression in the elderly. RQ 1: What is the role of the nurse in screening for depression in the elderly? RQ 2: What is the role of the nurse in the primary care in screening for depression in the elderly? RQ 3: What is the role of the nurse in screening for depression in hospitalized patients in acute care? RQ 4: What is the role of the nurse in screening for depression in seniors in long-term and home care? RQ 5: What rating scales and methods are used in screening for depression in the elderly? The thesis introduce the concept of depression. The following are specified the causes of and the important factors that affect depression in the elderly. It also deals the differences in the clinical symptomatology of depression in old age. It explains possibilities and various barriers in the diagnosis of depression. Another chapter introduces complete geriatric examination, diagnostic classification systems, possible screening methods and scales for detection of depression in the elderly population. It also deals methods of pharmacological and non-pharmacological treatment and its possible complications associated with older age. By reason of increased suicide rate caused by depressive disorder the issue of suicidal behavior in the elderly is introduced. The next chapter deals with the nursing process, which is used by nurses in practice. It consists of the evaluation of the patient's health condition, making nursing diagnosis, creating nursing plan and subsequent implementation and evaluation. The nursing process is also needy for providing quality care. The nursing process in the stage of nursing diagnosis, introduces possible nursing diagnosis for a patient suffering from depression, which are based on the latest classification. Finally is described the role of nurses in screening for depression in the elderly in different health facilities and their contribution to the timely evaluation of depression in the elderly. This chapter introduces the role of nurses, nursing screening and collaboration with a physician. The role of nurses in screening for depression in different medical facilities is based on the first phase of the nursing process of assessment. On the basis of objective and subjective information, the nurse will assess the overall health and mental condition of the patient. Primarily, it was investigated what is the role of the nurse in screening for depression. On the basis of content analysis and synthesis it was necessary to used and processed domestic and foreign literature. A number of relevant sources are the results of various studies and Meta-analyzes, mostly from abroad, but also from the Czech Republic. The thesis can serve as a basis for nurses. The result of this thesis is to create e-learning material available for students in the Faculty of Health and Social Sciences of South Bohemia in Ceske Budejovice in the tutorial called Moodle.

Nursing care in a hygienic and epidemiological regime from the patient's perspective.
KŘEPELOVÁ, Lenka
Considering contemporary lifestyle and possibility of travelling imported infections accrued and some illnesses come back that have not occurred nearly at us more. Not only haemorrhagic fevers and other highly infectious illnesses but also hospital multiresistant bacterial strains that mean high risk for patients constitute a threat. The number of nosocomial infectious grows still. The patient is in the case of suspicion or already diagnosed infectious illness isolated and treated in the infectious department or in the tribal department in the room with increased hygienic-epidemiologic regime. The patient is saved in a single room, the possibility of visits is reduced and the staff uses personal protective equipment. The man is holistic being and it can come due to isolation to lack of satisfaction of his/her bio-psycho-social needs. The aim of this thesis is to identify unsatisfied bio-psycho-social needs of patients in increased hygienic-epidemiologic regime and to describe changes in needs of the patient depending on the time of hospitalisation. The theoretic part describes the problematics of infectious illnesses, system of the care for the patient with infectious illness and changes in human needs in the period of the illness. The empiric part of the thesis deals with unsatisfied bio-psycho-social needs of isolated individual through quantitative research. The research suite was made up of 10 patients who were hospitalised in the room with increased hygienic-epidemiologic regime. The survey was carried out in the Hospital Jihlava by semistructured interview and the results of the survey were processed by opened coding by method paper and pencil. It is emphasized that the most needs of the patient have biological, psychical, social and even spiritual aspects. The rate of satisfaction with caregiving depends on the health condition and personality of the patient. Not small influence has the length of the hospitalisation, too. It was found out during the survey that the patients have not enough information about specifics of the care in the infectious department and that is why there is often a misunderstanding of necessity of barrier measures. It is possible to avoid useless misunderstanding through timely and suitable education. It was created an educational material with the title "Guide for patients hospitalised in the infectious department of Hospital Jihlava" for this purpose. Employees of the infectious department of Hospital Jihlava were informed with results of the research during a workshop, too.

Strategie oplozování u ryb s vnějším oplozením
SIDDIQUE, Mohammad Abdul Momin
Morphological properties, species specific differences, development, and function of egg envelopes are of importance for a better understanding of fertilization strategies as well as for captive reproduction. We reviewed morphology and the developmental stages of egg envelopes, mechanism of polyspermy block, and also the role of micropyle and cortical granules in polyspermy block for acipenserid eggs. The structure of the egg envelope is similar among the acipenserids, comprising an external envelope (thecal cells, basal lamina, and follicular epithelium), a five-layered oocyte envelope (adhesive layer, alveolar layer, epilayer, and zona radiata externa and interna) and a layer of oocyte matrix and cortical granules. The development of acipenserid egg envelope within the ovary comprises five stages, with further changes following fertilization. Moreover, we standardized the terminology used to describe the egg membranes which can minimize the confusions and be helpful for future work on acipenserids eggs as well as for other fish species. The sperm to egg ratio (required to fertilize eggs) and effects of pre-incubation of eggs in freshwater before fertilization were studied to standardized fertilization protocols for sterlet Acipenser ruthenus. Pre-incubation time had no effect on fertilization success at 430,000:1 and 43,000:1 sperm to egg ratios, while it was significant at the 4300:1 and 430:1 ratios. The use of adequate experimental suboptimal sperm to egg ratio revealed a positive effect of pre-incubation time, such that at the 430:1 ratio, 0.5 min pre-incubation increased the fertilization rate than 10 min. Transmission electron microscopy showed that pre-incubation of eggs in water for <10 min did not trigger a cortical reaction, suggesting that a low sperm to egg ratio 0.5 to 1 min pre-incubation of eggs in freshwater prior to fertilization can enhance fertilization rate of sterlet (minimally do not change fertilization). The effects of pre-incubation in seawater and the duration of egg receptivity were determined for fresh and over-ripe sea bass eggs. Our results revealed a significant effect of pre-incubation time for both the fresh (P < 0.01) and over-ripe eggs (P < 0.01). The fresh eggs had a higher fertilization success than over-ripe eggs. Fertilization success of eggs significantly declined for both of these treatments after 3 min of pre-incubation clearly indicated that sea bass eggs are able to be fertilized by sperm for up to 3 min after release into seawater. Effects of pre-incubation of eggs and activation medium on the percentage of eyed embryos for Ide Leuciscus idus were examined. At the eyed-egg stage, pre-incubation time was significant for the freshwater activation medium (P < 0.001), such that the percentage of eyed embryos declined across the pre-incubation time gradient. Activating medium had a significant effect on the percentage of eyed embryos for each pre-incubation time (P < 0.05). More precisely, freshwater produced the lowest percentage of eyed embryos at all pre-incubation times, whereas saline water and Woynarovich solution produced the highest percentage of eyed embryos at 0 s and 30 s before incubation. Examination of sperm traits showed no impact of activating medium on computer assisted sperm analysis parameters. Our results suggested that saline water or Woynarovich solution improve fertilization rate in Ide during fertilization. In conclusion, this thesis provides basic knowledge on gamete biology, role of egg receptivity period, effects of pre-incubation of eggs and different activating medium which can be useful to understand the fertilization strategies of different externally fertilizing fishes as well as standardize their fertilization protocol for captive reproduction.
