Individual human odor as a forensic trail in criminal proceeding made by contact or contactless transmission and its resistance to physical agents
Santariová, Milena ; Bartoš, Luděk (advisor) ; Chmelíková, Eva (referee)
The dissertation thesis consists of four papers that have been published in scientific journals.
Study n. 1
The need to recover evidence from water is quite common in criminal investigation. The article deals with the possibility to collect human scent from such objects and with the ability of specially trained dogs to match such scent samples with scent samples collected from detained suspects. During an experiment, designed as a blind one, it has been proved, that human scent can survive on submerged objects and can be later used for scent identification.
Study n. 2
To collect odors the Czech Republic Police use special fabric sorbents manufactured under the registered mark ARATEX. Before use the fabric sorbent is treated by water vapor sterilization. After the scent identification the sorbent is destroyed. The goal of the study was to verify if the vapor sterilization is effective enough to remove human scent that has already penetrated into the sorbent structure or in other words if the sorbent can be exposed to vapor sterilization and then used again. Specially trained dogs were used to match starting odors with target odors in the line-ups. The results showed that dogs are able to correctly match human odors even after they have being exposed to vapor sterilization.
Study n. 3
The purpose of the study was to determine the temperature at which the human scent is degraded so that a dog would not be able to identify it. In contrast to expectations, eight dogs used in the experiment almost flawlessly identified human scents from five scent donors exposed to temperatures of 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C, and 800°C. Only two of the dogs were able to identify 5 of 15 scent samples exposed to 900°C. No dog identified a scent exposed to 1000°C. Our study verified heat survivability of human scent far beyond existing expectations.
Study n. 4
We tested the hypothesis that if odor fallout (the release of a human odor onto an untouched object) in human subjects exists, then holding a hand above an absorbent will produce a detectable scent which will be subsequently matched in a detection test by trained dogs. Scents were collected from seven males to sterile cotton absorbent squares. The left hand was used to get the control scent and the right hand served as the target scent. Each experimental subject was sitting and his left hand was laid down on a cotton square for 3 min. The right hand was held 5 cm above another cotton square for 3 min. The scent identification was done by two specially trained police German shepherds. Both dogs performed 14 line-ups and correctly matched the collected scents of all test subjects. The results suggest the existence of human odor fallout, whereby a human scent trace is left by humans even if they do not touch an object.

Employment in a state-funded institution
Brožová, Milena ; Světlíková, Daniela (advisor) ; Pikola, Pavel (referee)
This bachelor thesis is focused on employment in a state-funded institution. It is divided into a theoretical and an empirical part.
The theoretical part deals with analysis of legal regulations and their interpretation. The method of description is used in this part. The focus in legal regulations is on the problems of a state-funded institution, namely on the legal position and functioning and on management. The focus is also on labour relations, from the general definition to the conclusion of employment for a fixed period of time. The analysis of legal regulations is complemented with interpretations of authors of specialized publications.
Direct and indirect quotations are used in the text and are marked with footnotes.
The empirical part of this thesis deals with the application of legal regulations in a particular state-funded institution. The order of researched areas is in accordance with the theoretical part. The method of comparison and study of documents and internal regulations are used for analysing the data.
The primary research has shown that the legal regulations are applied without difficulty. The discovered discrepancy between the used terminology and the terminology in the Civil code does not invalidate legal documents and thus there is no need to mark it as a defect which needs to be fixed. Suggestions for discussion have been made, for which measures were proposed in the concluding part. The suggestions relate to arrangement of employment for a fixed period of time and its change to permanent contract and to allowance from the founder as a financial mean of a state-funded institution.

One-Sided Random Context Grammars
Zemek, Petr ; Černá, Ivana (referee) ; Doc. In.g Petr Sosík, Dr. (referee) ; Meduna, Alexandr (advisor)
Tato disertační práce zavádí jednostranné gramatiky s nahodilým kontextem jako řízené gramatiky založené na bezkontextových gramatikách. V těchto gramatikách je ke každému pravidlu přiřazena množina povolujících symbolů a množina zakazujících symbolů a množina pravidel je rozdělena na množinu levých pravidel s nahodilým kontextem a množinu pravých pravidel s nahodilým kontextem . Levým pravidlem s nahodilým kontextem lze přepsat neterminál pokud se všechny povolující symboly vyskytují vlevo od přepisovaného neterminálu a žádný zakazující symbol tam přítomen není. Pravé pravidlo s nahodilým kontextem lze aplikovat analogicky, ale ona kontrola na přítomnost a nepřítomnost symbolů je provedena doprava od přepisovaného neterminálu. Práce je rozdělena na tři části. První část uvádí motivaci za zavedením jednostranných gramatik s nahodilým kontextem a umisťuje materiál pokrytý v této práci do vědeckého kontextu. Poté dává přehled základů teorie formálních jazyků a některých méně známých oblastí, jejichž znalost je nutná pro pochopení studovaného tématu. Druhá část tvoří jádro práce. Formálně definuje jednostranné gramatiky s nahodilým kontextem a studuje je z mnoha pohledů. Mezi studovaná témata patří generativní síla, vztah k jiným typům gramatik, redukce, normální formy, nejlevější derivace, zobecněné a LL verze těchto gramatiky. Třetí část této práce zakončuje diskusi několika poznámkami. Mezi ně patří poznámky týkající se aplikovatelnosti zavedených gramatik v praxi, bibliografie a otevřených problémů.

The Pump with a Diffuser with Stochastic Blades (Runner and Diffuser)
Dobšáková, Lenka ; Melichar, Jan (referee) ; Veselý, Jindřich (referee) ; Haluza, Miloslav (advisor)
This doctoral thesis studies the non-uniform blade cascade for centrifugal pumps. Influence of non-uniform blade cascade is investigated on the impeller and diffuser. A non-uniform blading impeller of pumps in this doctoral thesis was examined in terms of influence on efficiency characteristic. The idea of using non-uniform blading is to obtain a flat efficiency characteristic. Then the centrifugal pump could be used on larger scale of power with achieving a sufficiently high efficiency. The work is based on experimental measurements and numerical simulations of non-uniform hydraulic pump components. Non-uniform impeller and the diffuser were newly designed for this research. A new measuring track of small submersible pumps was needed to design and build for measurements. Different pump combinations with conventional hydraulics on one working point and hydraulics with non-uniform were measured. All measurements were evaluated and characteristics of efficiency, head and power were obtained for each measured combination. Some of pump combinations (which were measured in experiment) were numerically simulated by program Ansys Fluent. Data needed to evaluate the characteristic of efficiency and specific energy were collected from each numerical simulation. A theoretical consideration concerns the influence of non-uniform blade cascade applied on diffuser. The suggestion how to decrease hydraulic losses in canals was done. The theoretical consideration how to make a flat efficiency characteristic was made.

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. ...

Effect of a graduate of field of study Special Education - tutorship in practice of providers of social care
SALABOVÁ, Jana
Theoretical part of the thesis is divided into 4 main chapters. First one deals with the helping professions generally, their definitions and definition of the Special education - Tutorship branch of study per se.It also briefly touches the subject of readiness of the future graduates to deal effectivelly with the challenges of a career in the field of social services. Chapter number two is called Special education and it defines the subject of special education itself, it's purpose and inner structure. Third chapter focuses on social services. It brings up it's definition and types and forms of social services.It also contains the examples of the institutions which fall into this category and it's providers. Chapter number four, which happens to be the last one in the theoretical part of the thesis, covers the role and purpose of graduates of the special education - tutorship studies. It brings up the definition of a social worker, necessary prerequisites as well as beneficial personality traits and feautures. In a subchapter of chapter four is a short description of a pedagogue tutor. Definition who he actually is, who are proper candidates for this position, what are desired personality traits we look for in tutors and the actual content and purpose of their work in institutions providing social services. The end of chapter four is dedicated to a position of a social worker. His activities, the position and definition of a personal assistant and again personality traits needed for a successful career in this field. The objective of the practical part of the thesis is to describe working of Special education - tutorship studies graduates in practice. Particularly their experiences "from the field", how do they evaluate the level of skill of fresh graduates during their first encounters with the reality, how satisfied are they with their choice of a career so far and what was their motivation to pursue such career. Practical part of the thesis includes qualitative research. To meet the above objectives, data collection technique had been chosen using a structured interview with the respondents, who were graduates of Special education tutorship studies. You can tell by the results of this thesis that graduates in the field of social services apply mostly to lower positions as a social service workers, even though they are qualified to perform as a social workers. The age of clients with whom the respondents work ranges from childhood to senior. The motivation that led those questioned respondents to the decision to choose the area of social services varies. Some reported that they were influenced by the actual practical experience during their studies at the university, when both the work itself and their enthusiasm for the target group played role. Others expressed they had previous experience working with people with disabilities or they just wanted to acquire new experiences. Also, involvement of a family member and their previous education was a motivation. Job satisfaction is evident from observed data, and it also contributes to work done accurately and responsibly. Personal benefits for the respondents according to findings are usually their usefulness at work, new experiences they are getting and last but not least advances of their clients. As the biggest advantage the respondents usually mention variability of their work, target group and the clients in itself and the fact, that their work is highly satisfying and they basically work in a very pleasant team of individuals. On the other hand, not exactly satisfying financial reward and challenging working hours are mentioned as disadvantages. Special education - tutorship studies - the branch they've studied, is by the majority of respondents considered to be beneficial for them and they especially highlight practical impact of practice they completed during their studies and which included visits to various relevant institutions.
