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).

Portfolio diversification
ŠÍP, Martin
The goal of this bachelor thesis is to show how the choice of stocks impacts the portfolio diversification in relation to risk and return. The risk was calculated as standard deviation and historical return rate was considered. The theoretical part explains basic terms related with portfolio diversification, Markowitz model, capital stock and most important factors that lead to the optimal portfolio creation such as return, risk and covariance. The practical part explains in detail, how to create an optimal portfolio. Ten companies from different sectors were randomly chosen for this bachelor thesis. These companies' shares are traded on the New York Stock Exchange. The covariance of these shares is lower than one. The next step was to calculate historical return rate and historical risk of portfolios. The highest value of historical return rate was 2.31 % and the lowest value of historical risk achieved 22.77 %. Subsequently, the efficient frontier was determined. The efficient frontier is the set of optimal portfolios that offers the highest expected return for a defined level of risk or the lowest risk for a given level of expected return. The lowest value of portfolio risk was 2.97 % with a return of 1.38 % and the highest value of portfolio risk was 4.03 % with a return of 2.13 %. The investor chooses the portfolio which maximizes his expected benefit.

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.

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.
