Evaluation of chat bots
Hazdra, Jan ; Sigmund, Tomáš (advisor) ; Čermák, Radim (referee)
This thesis deals with the evaluation of theability of machines to imitate human behavior. Presents a brief history of the development on the field of artificial intelligence and intelligent machines, specifically chat botsand describes their evolution throughout the 20th century. It describes the most important features and building blocks of chat bots, including the most widely used programming languages for creating them.It also describes the theory of A. Turing, the test and the imitation game, on which is based methodology for evaluating chat bots. Then it also examines the criticism of the Turing's test by J. R. Searle's chinese room argument that is used for its better understanding and finding its boundaries. The work also describes H. Dreyfus's assumptions, which led to optimism in the late 90s in development in artificial intelligence and limits of artificial intelligence, on which he pointed out. The main objective is the metodology proposed in the second part, which is used for comparing selected chat bots and then used for their evaluation. Overall evaluation consists of evaluations in the sub-categories in which will be individual chat bots scored. The methodology is based on the Turing test, which slightly modifies, but also extends thanks to the ideas of other authors.

The stability of biologically active compounds in elderberry (Sambucus nigra L.) inflorescence during processing
SUCHÁ, Renata
This thesis examines the stability of rutin in the inflorescences of the elder during processing. Elder (Sambucus nigra L.) is a medicinal plant that was used for medical purposes as early as in the Middle Ages. Both flowers (Flos Sambuci) and fruit (Fructus Sambuci) of the elder are on the list of official medicinal products of the State Institute for Drug Control. The main active phenolic substance is flavonoid rutin. Flavonoids are phenolic substances of plant origin. Among the best known properties of these substances is their antioxidant activity. They protect the low density blood lipoproteins from the oxidation modifications that cause the development of arteriosclerosis and hypertension. As a medical plant, the elder is used especially for the preparation of a medicinal drink. It is also commonly used as a material for the preparation of syrup. This product serves as a basis for a refreshing and tasty drink and lately is has also started to be sold in shops. For comparison, five single-flower syrups from the elderflower by different producers were bought. A method of preparation of the elderflower syrup was devised, based in one case on frozen elder inflorescences and in the other on dried inflorescences. The plant material came from wildly growing shrubs and it was collected in June 2013. Altogether, 8 syrups were prepared in the laboratory, 4 of them from fresh material and 4 from dried material. Two different methods were used. The first one was based on extraction using sugar solution, the second one on extraction using water solution where sugar was added afterwards. Another added substance was ethanol. The method for measuring the amount of rutin in the samples was a combination of two extraction steps. The first step was the usual exraction using aqueous methanol and the second step was extraction using a solid sorbent (SPE). The analysis of fresh and dried material concluded that dried elderflowers contain many times more rutin than fresh elder. Among the commercially produced syrups, the "Kitl Syrob Bezový" contained most rutin; a little less rutin was found in "Hamé Bylinný sirup Bezový květ". The concentration of rutin in the syrups prepared in the laboratory was much higher than in the commercial products. By using different methods of syrup preparation and their subsequent analysis, it was found that the syrups prepared from the dried inflorescences contained a higher amount of rutin than the syrups produced in the same way, but from frozen material. Addition of a small amount of ethanol had no effect on extraction of rutin from inflorescences. Free quercetin, which indicate a decomposition of rutin, wasn´t found in any of produced syrups. The produced syrups were used for the preparation of a drink and then underwent sensory analysis. The paired two-sided preference test included pairs of drinks consisting of a fresh elder drink and dried elder drink. The results showed that the evaluators preferred syrups from dried elderflowers in two of the cases, while in the other two evaluated pairs, the results were not statistically significant. In all cases, the evaluators most often found small and middle differences. The gained results show that the best method of syrup preparation uses dried plant material and sucrose solution as the extraction agent. The syrup prepared in this way contained most rutin and at the same time showed the smallest losses of this substance, which is beneficial to human health. Furthermore, it also tasted better in comparison with syrup prepared in the same way, but from fresh material.

International involvement in the peacebuilding process on Sri Lanka
Mojžíš, Michal ; Havlová, Radka (advisor) ; Burešová, Jana (referee)
The final months of Sri Lankan civil war, the 26 year military campaign between the Government of Sri Lanka and the insurgent separatist organization Liberation Tigers of Tamil Eelam, are marked by allegations of war crimes committed by both parties of the conflict, including attacks on civilians, summary executions of prisoners, enforced disappearances, restrictions on humanitarian assistance and recruitment of children. Since the attempts to put the Sri Lankan issue on the agenda of the United Nations Security Council failed on the unwillingness of China and Russia, the UN bodies in Geneva have taken a leading role in promoting the peacebuilding process on the island. The thesis aims to analyse the impact of the Geneva-based human rights bodies, in particular of the United Nations Human Rights Council, on the process of reconciliation in Sri Lanka, for which is crucial that the alleged violations of human rights in the last months of the civil war would be properly investigated and that the perpetrators would be held accountable. In order to put the activity of the UN Human Rights Council into broader context, the paper will examine the political development in Sri Lanka since the end of the civil war in 2009 as well as the failed efforts of Sri Lankan governments to launch the process of reconciliation.

Dynamic model of human resources in project management
Hančar, Michal ; Mildeová, Stanislava (advisor) ; Šviráková, Eva (referee)
This thesis is focused on dynamics of soft factors influencing workers during projects. These factors include motivation, workplace atmosphere, team synergy of workers and their emotions, and attribute of project manager who manages the project. Identification of soft factors and their relationships was achieved by examination of scientific literature in psychology and system dynamics. Description of managing project matters was achieved by examination of scientific literature dealing with project management. The main objective of this thesis is to create a dynamic model which simulates behavior of these soft factors influencing the project staff. The primary metric of the model is efficiency of workers participating on the project based on input parameters. Validation of the model was achieved by verification of historic behavior of key elements. Results of validation experiments correspond with historic behavior with roughly 95 % accuracy. At the end of this thesis is presented an ICT project case study. Based on the results of simulation experiments is performed a scenario analysis which tries to bring possible suggestions for project management.

Introduction to bio art
Šperanda, Nina ; SILVERIO, Robert (advisor) ; JANOŠČÍK, Václav (referee)
Bio art is a contemporary art practice that works with living organisms (except humans) or is created in cooperation with living organisms. It is relatively new art movement that is rooted deeply inside the history of evolution, domestication of animals and plants, technological discoveries, their development and science. Never before was art questioning its ethics and aesthetics in such profound, molecular and sub-molecular way.
In this work I will consider the historical influences and conditions that led to current developments in the field. I will also try to explain the problematics of defining what bio art is and try to clarify the associated terminology. Most relevant and ground breaking works in the field will be mentioned as some new recent developments.
Aesthetics of bio art is also an important subject often set aside by the ado around ethics of it. It is an extremely important subject to be considered when talking about bio art and I will try to sketch out a brief outline of it with references to philosophy and contemporary bio art theory.

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.
