Phenolic complex of medicinal plants
Vaníčková, Klára ; Orsák, Matyáš (advisor) ; Hniličková, Helena (referee)
This thesis deals with medicinal plants, that contain phenolic complex. Emphasis on interdisciplinary relations with the chemistry and the use of theory in practical life. At the beginning, I also focused on the concept of health and lifestyle, which is an inherent part of that topic. Content is also the use of medicinal plants, basic plant description and important characteristic of the phenolics contained in plants. At the theoretical part is processed an overview of selected kinds of medicinal plants to draw attention to the content of the substance, especially with the phenolic complex special effects and their possible use.

The evelutionary crises, thein sense and importance, asserting of ethics and social work with solution of adolescence
HOMOLKOVÁ, Lenka
This work is engaged in the reflexis of endangerous of behaviour in the season of adolescence. The first chapter offers a complex, compendious acquainting with life crises in the developement of man with the intention on the crise of adolescence. In conection with this season, there are described fundamental changes that can be the source of critical moments. The second chapter is following up with a critical moments that describes concrete forms of social work with young generation and ethics questions and dilemmas. The third chapter enriches the previous two of the theory of social work that facilitates a daily practise of workers and it specifies for anybody what to do. The last chapter of the work is about the reflex of ethics questions in the social work with adolescence people and their crises and finding the question on it or finding the perspective solutions.

Is There Something Beyond AI? Frequently Emerging, but Seldom Answered Questions about Artificial Super-Intelligence
Wiedermann, Jiří
Using the contemporary theories and views of computing and of cognitive systems we indicate possible answers to the following frequently asked questions about artificial intelligence: (i) what is the "computational power" of artificial cognitive systems?; (ii) are there "levels" of intelligence?; (iii) what is the position of human intelligence w.r.t. the "levels" of intelligence?; (iv) is there a general mechanism of intelligence?; (v) can "fully-fledged" body-less intelligence exist?; (vi) can there exist a sentient cloud? We give qualified arguments suggesting that within the large class of computational models of cognitive systems the answers to the previous question are positive. These arguments are mostly based on the author's recent works related to this problematics.

Does oxidation make the organic aerosol coatings more hydrophilic? Insight from molecular dynamics study of oxidized surfactant monolayers
Roeselová, Martina ; Khabiri, Morteza ; Cwiklik, Lukasz
Organic compounds are ubiquitous in atmospheric aerosols. The morphology and structure of the organic phase affect the optical properties of the aerosols, their heterogeneous reactivity as well as their ability to nucleate cloud droplets and ice particles. It is commonly assumed that atmospheric oxidative ageing of the organic material, leading to the formation of polar groups such as carbonyl (=O), hydroxyl (-OH) and carboxylic acid (-COOH), will render the aerosol particle surfaces increasingly more hydrophilic, hence, able to take up more water. Field measurements have shown that a large fraction of the organic material found in aerosols are surface active compounds, such as fatty acids and lipids(Tervahattu, 2002 and 2005). An inverted micelle structure, with an aqueous core surrounded by an organic surfactant layer, has thus been proposed for aqueous aerosols, both marine and continental (Donaldson, 2006). While recent experiments suggest the existence of more complex structures, such as organic inclusions and surfactant lenses (Dennis-Smither, 2012), a monolayer (ML) of surface active organics on an aqueous subphase (the so called Langmuir monolayers) represents the basic model system used in laboratory studies aimed at elucidating the effect of oxidative processes on structural properties of organic coatings on aerosol particles. In our previous work, we used molecular dynamics computer simulations to study the structure and stability of oxidized phospholipid MLs (Khabiri, 2012). In this contribution, we employed the molecular dynamics simulation technique to investigate – with atomistic resolution – structural changes occuring in a fatty acid ML upon moderate degree of oxidation.

An attempt to implement Compositional Models in Dempster-Shafer theory of Evidence
Kratochvíl, Václav
It has been published recently that some of the ideas for representation of multidimensional distributions in probability theory can be transferred into Dempster-Shafer theory of Evidence. Namely, they showed that multidimensional basic assignments can be rather efficiently represented in a form of so-called compositional models. These models are based on the iterative application of the operator of composition, whose definition for basic assignments has been introduced in [5]. It appears that a software tool supporting computations within compositional model is necessary for additional theoretical research in this framework. In this paper we will familiarize the reader with our first attempts and basic problems of the implementation itself.

Complex simulator of the solar irradiance
Petrov, Roman ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
This work consists of a theoretical part, which deals with various ways of mathematical equations to model the thermal photovoltaic cell. Thermal modeling describes a photovoltaic cell temperature, and heat capacity of the photovoltaic cell. This temperature is usually function or directly dependent on the intensity of solar radiation. In the theoretical section explains several ways to model thermal photovoltaic cells. Thermal modeling is outside the scope of this paper, it is mainly the modeling of solar irradiance, which is discussed in detail in the next section, and then in the practical part. The practical part is concerned with constructing mathematical equations that describe the intensity of solar radiation. These mathematical equations are then used to build a mathematical model. The actual mathematical model is created in a computer program PSCAD, wherein the main input parameter of the intensity of solar radiation. This model can simulate the course of the sun, for which it is necessary to set various parameters such as: region, time of day, the seasons, but also has a function that is essential for modeling of solar radiation intensity, and it is cloudiness. Cloud is fundamentally changing the size of the radiation intensity, and its direct constituents. After compiling a complex simulator of solar irradiance, this simulator is tested for its validation in form of doing couple of graphical runs of intensity of solar radiation for various locations on Earth, which are time dependent.

Personality, creativity and complexity of thought
Chadimová, L. ; Urbánek, Tomáš
Presented study introduce the correlation of creativity, personality and cognitive complexity. The structure of cognitive processess has been great topic since the turn of 20th century. The research on cognitive styles have brought many new findings on the interconectedness of personality and cognitive processes such as perception, thinking and decision making, memory etc. Theories of cognitive complexity represent one contribution of this period, which aims on how are the cognitive processess structured, how this structure affects the effectivity of decision making and how it’s affected by different internal or external factors such as sex, age, \npersonality, social context, time pressure etc . In the first part of our research we conducted an analysis of \ncorrelation between divergent thinking factors and cognitive complexity measures following the approach of P. \nSuefeld and P.E. Tetlock. Figural and verbal fluence, flexibility, elaboration and originality were measured by \nsubtests Torrance test of creative behaviour and Guilford Alternative uses test. Cognitive complexity was scored \non the Paragraph completion test data following the Integrative/Conceptual complexity scoring manual (Baker-Brown et al., 1992). In the second part of study we conducted correlation study of cognitive complexity and Big Five personality traits (measured by Czech version of NEO-FFI by Hřebíčková & Urbánek, 2001). The article gives a summary of main findings of our studies and briefly sketch out the questions and hypotheses for future research on the complexity of thought.
