Hodnocení spolehlivosti lidského činitele v procesní průmyslu
Výzkumný ústav bezpečnosti práce, v.v.i.
Today, the human factor has become a common theme in many sectors of human activities. These include the military sector and the military, because improper use of weapon systems or their conscious abuse is considered a very serious threat. In terms of civilian operations are mainly operating nuclear power plants, chemical plants, air transport, but also health, where great emphasis is placed on reliability (and accuracy) of man.

Evaluation of the effectiveness of teaching vocational subjects depending on physical activity before schooling.
Janošíková, Martina ; Hanušová, Marie (advisor)
The period of transition to secondary school brings substantial changes in the requirements for study obligations, autonomy, communication, expression, or separated from their families in the form of staying at the dormitory. Students enrolled in sport centers, in addition to these changes, still struggling with the responsibilities associated with sport. Because they are students first through fourth grades of secondary schools and secondary vocational schools, an age when image self-I am, what I believe in, arises in interactions with the outside world and their own experience, plays a very important role to influence the environment, educators, teachers and trainers, with which students spend most of their time in practice. This study looks at students comprehensively in terms of personal development as a multifactorial biopsychosocial unit, in terms of cognitive and motivational processes, states and properties from the perspective of social psychology dealing with the interactions, relationships and communication, psychology of individuals within the social group and its importance for the development of the individual . It monitors conditions and educational outcomes in terms of educational psychology, dealing with forming properties, opinions, attitudes and value orientation from the perspective of educational psychology.

Design of Experiment for Non-Stationary Processes of Production
Jadrná, Monika ; Macák, Tomáš (advisor)
The doctoral thesis is concerned with the services sector and the area of mass production. Particularly, the optimization of the product portfolio of the travel agency and the optimization of production rounds of ammunition.
The theoretical part deals with the current overview of discussed topic. Further, the terminology and methods of the decision-making process are defined to support decision making. The theoretical basis of research focused on the choice of appropriate input variables in the area of services, and on the choice of a particular material option in the production area and appropriate equipment for the production. The theoretical part forms the basis for the practical part of the thesis.
For the doctoral thesis was chosen an enterprise operating in the defined sector. Product portfolio for the services sector is optimised using Fuzzy logic and Fuzzy sets so that the enterprise can maintain its competitiveness in todays highly ambitious market. Product portfolio for manufacture is optimised for achieving desired properties of the product.
The main aim of the thesis is to propose a new methodological approach for the management of selected business processes in their nonstationary time course. The aim of the practical implementation is to verify the functionality of the proposed methodological approach, both in the area of services and in the field of mass production.

Art and architecture of the Ethnographic exhibition 1895
Mědílková, Veronika ; Prahl, Roman (advisor) ; Machalíková, Pavla (referee)
Title of the thesis: Art and architecture of the Ethnographic exhibition 1895 The topic of the presented diploma thesis is the reconstruction of artist and item list presented on the Ethnographic exhibition of 1895, which was held in the premises of Holešovice Fairground in Prague from May 15 to September 28, 1895. Despite being one of the most important exhibition events held in Bohemia in the 19th Century (Jubilee Exhibition of 1891 - Ethnographic Exhibition of 1895 - Architecture and Engineering Exhibition 1898), it has not yet been systematically covered - not even from the history of art perspective. Based on the original material (leaflets, catalogues, guide-books) the thesis attempts to re- introduce the original public image of the exhibition and the character of the exposed items. The chapters of the thesis deal with the exhibition banner, the architecture (The Old Prague and Sample Village exhibitions), paintings, sculptures, commercial art (exhibition souvenirs). The thesis also attempts to trace the items and sketch their fate after the exhibition was over.

Population genetic analysis of Old Kladruber horse
Vostrá Vydrová, Hana ; Majzlík, Ivan (advisor) ; Karel, Karel (referee)
The Old Kladruber horse, along with the Lipizzaner horse, Andalusian horse and Lusitano horse, is of the original Italo-Spanish type. The Old Kladruber horse is kept in two colour varieties (grey and black). Because the population is closed, there is a concern about the loss of genetic variation. The genetic diversity and population structure were analysed in the Old Kladruber horse breed based on the pedigree information of animals that were registered in the Studbook to identify factors that may have affected the genetic variability of the breed. Pedigree records collected from 1729 to 2013 contained information on 7971 animals that were used in the analyses. The pedigree depth was up to 33 generations, with an average of 15.1 complete generations. The effective number of founders and ancestors contributing to the current genetic pool was 92.69 and 17.16, respectively. The average values of the inbreeding coefficient were as follows: 13% (with a maximum value of 29%) for the reference population (individuals that can currently take part in reproduction, n=612), 11% for the grey variety (with a maximum value of 25%) and 15% for the black variety (with a maximum value of 29%). The proportion of inbred animals was high (99%). The average rate of inbreeding in the reference population was 1%: 0.8% for the grey variety and 1.1% for the black variety, and the respective estimates of the effective population sizes were 52 for the reference population, 62 for the grey variety and 45 for the black variety. The estimated percentage of genetic diversity lost due to non-random mating within subpopulations and the reference population was 1.0, 1.0 and 1.2%, respectively. The total loss of genetic diversity in the reference population, in the grey variety and in the black variety was 11%, 13% and 17%, respectively.

Provision of alternative refuse collection for a real estate surrounded by foreign property
Kvapil, Radek ; Štindl, Michal (referee) ; Klika, Pavel (advisor)
The thesis deals with possible ways of drainage and wastewater disposal. The issue of wastewater discharge to the environment has been closely monitored in recent years, and there is an apparent effort to improve the current situation.The dissertation discusses and compares three selected options – access to improved sanitation, building reservoirs and domestic wastewater treatment plant.The final section is dedicated to a comparison of acquisition and operating costs over time and to subsequent evaluation of the most suitable option. For the sake of clarity and assessment of potential solutions, the locality in the administrative area Vysoké Mýto - Domoradice has been selected as a model. The local authorities have been designing a public storm sewer, and given that it is surrounded by land, this issue will need to be addressed.

Comparing the Price of a Transportation Structure and the Actual Costs Incurred in Various Stages of Construction
Nezbeda, Jiří ; Zímová, Štěpánka (referee) ; Kosová, Jaroslava (advisor)
This diploma thesis deals with the calculation of the cost of the building work in order to create the price, which at the stage of the contract becomes a selling price, and the costs are fixed as a budget. The subject of this work is to monitor the development of costs in time so that the cost does not exceed the budget and the construction did not get into the negative result. Then set the price by its own methods (item budget, calculation according to budget indicators) and compare the prices and costs thus obtained from different phases of construction between each other and determine the differences. In this work is monitored and compared the cost of a construction contract and its costs in the construction stages. In the practical part,is used the method of direct comparison of cost and price values over time, in the form of different outputs from the controlling program and outputs from compiled item budget and the calculation of the construction. Analyzing the differences between these costs and their evolution over time by more detailed examination of item budgets and cost calculations, they determine the origin of these deviations. In conclusion, is proposed measures for a particular transport structure whitch was handled by the author as"master and co-ordinator of the construction".

Point to Line Mappings and Other Line Parameterizations not only for Hough Transform
Havel, Jiří ; Kälviäinen, Heikki (referee) ; Lefevre, Sebastien (referee) ; Herout, Adam (advisor)
Tato práce se zabývá Houghovou transformací (HT). HT je nejčastěji používána pro detekci přímek nebo křivek, ale byla zobecněna i pro detekci libovolných tvarů. Hlavní téma této práce jsou parametrizace přímek, speciálně PTLM - zobrazení bodů na přímky. Tyto parametrizace mají tu vlastnost, že bodům v obrázku odpovídají přímky v parametrickém prostoru. Tato práce poskytuje důkazy některých vlastností PTLM. Za zmínku stojí existence páru PTLM vhodného pro detekci a efekt konvoluce v obrázku na obsah parametrického prostoru. V práci jsou prezentovány dvě implementace HT. Obě využívají k akceleraci grafický hardware. Jedna využívá GPGPU API CUDA a druhá zobrazovací API OpenGL. Jako aplikace detekce přímek je uvedena část detekce šachovnicových markerů použitelných pro rozšířenou realitu.

Extensions to Probabilistic Linear Discriminant Analysis for Speaker Recognition
Plchot, Oldřich ; Fousek, Petr (referee) ; McCree,, Alan (referee) ; Burget, Lukáš (advisor)
Tato práce se zabývá pravděpodobnostními modely pro automatické rozpoznávání řečníka. Podrobně analyzuje zejména pravděpodobnostní lineární diskriminační analýzu (PLDA), která modeluje nízkodimenzionální reprezentace promluv ve formě \acronym{i--vektorů}. Práce navrhuje dvě rozšíření v současnosti požívaného PLDA modelu. Nově navržený PLDA model s plným posteriorním rozložením modeluje neurčitost při generování i--vektorů. Práce také navrhuje nový diskriminativní přístup k trénování systému pro verifikaci řečníka, který je založený na PLDA. Pokud srovnáváme původní PLDA s modelem rozšířeným o modelování neurčitosti i--vektorů, výsledky dosažené s rozšířeným modelem dosahují až 20% relativního zlepšení při testech s krátkými nahrávkami. Pro delší testovací segmenty (více než jedna minuta) je zisk v přesnosti menší, nicméně přesnost nového modelu není nikdy menší než přesnost výchozího systému. Trénovací data jsou ale obvykle dostupná ve formě dostatečně dlouhých segmentů, proto v těchto případech použití nového modelu neposkytuje žádné výhody při trénování. Při trénování může být použit původní PLDA model a jeho rozšířená verze může být využita pro získání skóre v případě, kdy se bude provádět testování na krátkých segmentech řeči. Diskriminativní model je založen na klasifikaci dvojic i--vektorů do dvou tříd představujících oprávněný a neoprávněný soud (target a non-target trial). Funkcionální forma pro získání skóre pro každý pár je odvozena z PLDA a trénování je založeno na logistické regresi, která minimalizuje vzájemnou entropii mezi správným označením všech soudů a pravděpodobnostním označením soudů, které navrhuje systém. Výsledky dosažené s diskriminativně trénovaným klasifikátorem jsou podobné výsledkům generativního PLDA, ale diskriminativní systém prokazuje schopnost produkovat lépe kalibrované skóre. Tato schopnost vede k lepší skutečné přesnosti na neviděné evaluační sadě, což je důležitá vlastnost pro reálné použití.
