Testing Learning of Restarting Automata using Genetic Algorithm
Kovářová, Lenka ; Mráz, František (advisor) ; Černo, Peter (referee)
Title: Testing the Learning of Restarting Automata using Genetic Algorithm Author: Bc. Lenka Kovářová Department: Department of Software and Computer Science Education Supervisor: RNDr. František Mráz, CSc. Abstract: Restarting automaton is a theoretical model of device recognizing a formal language. The construction of various versions of restarting automata can be a hard work. Many different methods of learning such automata have been developed till now. Among them are also methods for learning target restarting automaton from a finite set of positive and negative samples using genetic algorithms. In this work, we propose a method for improving learning of restarting automata by means of evolutionary algorithms. The improvement consists in inserting new rules of a special form enabling adaption of the learning algorithm to the particular language. Furthermore, there is proposed a system for testing of learning algorithms for restarting automata supporting especially learning by evolutionary algorithms. A part of the work is a program for learning restarting automata using the proposed new method with a subsequent testing of discovered automata and its evaluation in a graphic form mainly. Keywords: machine learning, grammatical inference, restarting automata, genetic algorithms

Charles University, Faculty of Pharmacy in Hradec Králové, Department of Biological and Medical Sciences Candidate: Mgr. Lenka Kovářová Supervisor: PharmDr. Miroslav Kovařík, Ph.D. Title of thesis: Association of phase angle with parameters of energy metabolism in patients with COPD Keywords: Chronic obstructive pulmonary disease, energy metabolism, indirect calorimetry, phase angle Chronic obstructive pulmonary disease (COPD) is a serious inflammatory disorder with constantly rising global prevalence. In addition to the characteristic irritation of respiratory tract with a progressive decline in pulmonary function, it is associated with significant systemic effects that contribute to the severity of the health condition. Moreover, metabolic changes related to ongoing systemic inflammation including increased respiratory demands, inappropriate nutritional supplementation and pharmacotherapy are observed in patients with COPD. In this work we focused on finding the association between phase angle (PA), the cell mass predictor obtained with bioelectrical impedance analysis and parameters of energy metabolism determined by indirect calorimetry. In total, 50 patients with a stable COPD were analysed, who were further divided by gender and measured PA with a limit value of 5. In group with PA < 5, we...

Šindlerová, Hana ; Bunc, Václav (advisor) ; Kovářová, Lenka (referee)
Title: Innovativ ways to affect overweight and obesity (use of the machine Body - Space VacuTherm). Objectives: The aim of this thesis is to evaluate if walking on Vacutherme encourages and accelerate body fat loss and figure forming as advertisements claim. Based on my own measurements of the clients of our clinic MS Clinic in Slaný I will examine body weight loss, particularly body fat loss, decrease of centimeters of those areas that are exposed to vacuum and change in body composition. I compare the results of clients enrolled in group used to weight reduction only VacuTherm lesson in the machine, with clients of the second group, which combine lessons in the machine with another physical activity attending at least 2 times a week for longer period of time. Methods: To get results important for bachelor thesis I chose only measurement method. For data processing, this method is most accurate. I used two forms of measurement. With one presentation helped me body analyzer Tanita BC-1000, which provided me with information that can not be measured by conventional methods. The second option is a common way of measuring the circumference of lots tracked to within one centimeter. At work I examine a group of 20 women who underwent diagnostic input on physical analyzer, where they were measured value...

Peteříková, Vendula ; Bunc, Václav (advisor) ; Kovářová, Lenka (referee)
Title: The Nutrition Habits and Knowledge of middle and long distance runners Targets: The thesis main target is to determine dietary habits of endurance men and women runners, their interest in health nutrition and their nutrition information sources. Another aim to achieve is to find out their basic knowledge of body composition and human nutrition. Methods: The thesis was worked out on the base of questionnaires , that were prepared with regard to the author personal experience and knowledge. The questionnaires were handed in personaly to the respondents at runners competition, as soon as the race was finished and most of the runners used to wait for their results. The respondents were kept in anonymity in order to ensure as much objective answers as possible. The meaning of questionnaire completion was explained by the author to each of the responding runners. The validity of the questionnaire was consequently confirmed by the mean of guided interview between the author and the runner responded. Results: Endurance runners are keen on following the health nutrition principles. The dietary habits of the major part of the respondants correspond to requirements related to the field of energy-intensive sport. Most of the runners do not use energy bars and nutritional supplements. On the base of the...
Comparison of heart rate and external performance at selected field tests for determining maximum heart rate for bicyclists and triathletes when cycling.
Podrazil, Tomáš ; Horčic, Josef (advisor) ; Kovářová, Lenka (referee)
Title: Comparison of the heart rate values and external performance is based on selected field tests determining maximal heart rate in cycling of cyclist and triathletes Objectives: Objective of thesis is to determine the values of maximal heart rate and external performance from selected field tests in cycling and compare them with one another. Methods: Five cyclist were measured in field tests and acquired results were used to create the graphs and tables. Data were obtained by cycling performance meter Powertap and cycle computer Garmin Edge 500. For the analysis of the measured data was used software Garmin Connect. Results: Based on the results of thesis it can be stated, that the measurement turn out as we expected. The difference of maximal heart rate between test-A and test-B is differed by 3-5 beats, which is not decisive. Both tests can be used for determine maximal heart rate. These tests are suitable for measuring the performance of athletes. Maximal heart rate is not in present an important indicator for training of fitness of individual. For training I would suggest to take a test of lactate curve in the laboratory. Keywords: cycling, external performance, heart rate, terrain test, Powertap
Somatotype comparison of current UK FTVS students and UK FTVS students forty years ago
Zapala, Michal ; Honsová, Šárka (advisor) ; Kovářová, Lenka (referee)
Title: Somatotype comparison of current UK FTVS students and UK FTVS students forty years ago. Objectives: Main aim of the theses is to compare the current level of student's somatic prerequisites to successful performance studies at UK FTVS in comparison with the somatic level of students studied forty years ago. Another aim of the theses is to illustrate method for measuring body fat by calliper. Subject and Methods: The total set consists of 901 somatotypes of students UK FTVS. Somatotypes were processed from protocols on the results of measurements, which contains the components values of somatotype and somatic parameters necessary for their determination. Processed values of somatotype were compared through statistical processes and through somatocharts. The illustration was created with a pencil simply in a lines with a minimal of shading. Results: Endomorphic components of somatotypes increased in a comparation with a set of students who studied fourty years ago. Higher values could have result in difficulties with fulfilment of practical credit requirements of endurance skills. Conversely mesomorphic components are lower against second set of students. It may result in difficulties with fulfilment of practical credit requirements of power skills. Keywords: somatotype, retrospective study,...
Vágní informace na konečných abecedách a její monotónní charakteristiky
Kovářová, Lenka ; Beneš, Viktor (advisor) ; Kupsa, Michal (referee)
Title: Vague information on finite alphabets and its monotonous characteristics Author: Mgr. Lenka Kovářová Department: Department of Probability and Mathematical Statistics Supervisor: prof. RNDr. Viktor Beneš, DrSc. Abstract: The bachelor thesis is focused on information-theoretic source of messages with vague recognition from a final general alphabet. The aim of this work is to compile an overview of existing approaches to entropy and information. There were published several approaches how to convert to the fuzzy set theory the concept of entropy, which was originally introduced in physics, mathematically expressed as an additive-probability model and adjusted for Shannon probabilistic information source. Most of these approaches maintains the additive-probability model, while the emphasis in the theory of fuzzy sets is laid on the characteristics of minimum and maximum.
