Paralelní evoluční algoritmus EDA využívající teorii kopulí / Parallel Evolutionary Algorithm EDA Based on Copulas

Hyrš, Martin Unknown Date (has links)
In my thesis I~ deal with the design, implementation and testing of the advanced parallel Estimation of Distribution Algorithm (EDA) utilizing copula theory to create a~ probabilistic model. A~new population is created by the process of sampling the joint distribution function, which models the current distribution of the subpopulation of promising individuals . The usage of copulas increases the efficiency of the learning process and sampling the probabilistic model. It can be separated into mutually independent marginal distributions and the copula , which represents the correlations between the variables of the solved problem. This concept initiated the usage of the parallel island architecture , in which the migration of probabilistic models belonging to individual islands ' subpopulations was used instead of the migration of individuals . The statistical tests used in the comparison of the proposed algorithm ( mCEDA = migrating Copula - based Estimation of Distribution Algorithm ) and the algorithms of other authors confirmed the effectiveness of the proposed concept .

Občanská stavba / Civil building

Bartošová, Andrea January 2020 (has links)
Basic of this Diploma thesis is Civil construction in Kostelec nad Orlici, which is in a part of city, where is planning off-grid community housing. Part of off-grid community housing is considered a partially sistainable civil construction, serving both for cultural use through the club, for commercial purposes such as various salons (hairdresser, massage or shop), as well as for sports activities with the possibility of small refreshments, such as bouldering, climbing wall and exercise hall. Four sustainable (off-grid) familly houses, which aren´t the subject of this thesis, are considered. Object SO01 – Civil construction is designed as a partially basement, two floors. The shape of the object is designed as several blocks with different height levels. From a material point of view it is a wooden building from the system of large-format laminated wood panels (CLT). The basement is designed with a waterproof reinforced concrete so-called white tub and prefabricated ceiling panels SPIROLL. A facade is made of wooden cladding, cement-fiber boards or thin-layer silicone plaster. A roof of the object is partially flat (vegetation and walkable) and a shed roof with a slope of 5°. A dance hall and the rest of the club + exit is located in the basement. A sanitary facilities, a technical room and a main entry with reception is also located in the basement. Right in the middle of the building is a climbing wall that runs across all floors. To the right of the climbing wall is a shop, exercise hall and staircase. To the left side are a sanitary facilities, a boulder (low climbing wall) and separate staircase for a office space on the 2nd floor. Behind the climbing wall is a bistro with entry for a terrace and entry for the club. There are some establishments like a hairdresser, a cosmetic salon, a tattoo salon and a massage salon on the 2nd floor. There are an entrance to a terrace above the bistro and a staircase to an attic and to second terrace as well on the 2nd floo

CHINA IN GLOBAL AND REGIONAL POLITICS IN THE 21ST CENTURY - GEOPOLITICAL CLASH WITH JAPAN, INDIA, USA, RUSSIA AND EUROPE Mgr. Martin Petrtýl Supervisor: Doc. Dr. Bořivoj Hnízdo, PhD. Institute of Political Studies, Faculty of Social Sciences This dissertation discusses the current and future role of China in the 21st century. I worked with the idea to prepare a systematically detailed analytical study of the country in relation to its surroundings as well as its internal environment for more than 8 years, including many interruptions. I, above all, contemplated about the way how to truly scientifically, i.e. credibly, it means in the maximum possible the limits of verifiability, develop a full work that could hold up to the colleagues from the scientific community and myself. It is logical it was and is my attempt to allow minimal possibility of any criticism of this work for its formal, content, or other deficiencies. First, I decided to analyse in some detail the currently known theoretical approaches and methods of study, not only in political sciences, especially those used by political geographers, but also in other related fields, especially in the field of study of international relations, sociology, political science or general security studies. I did not want to study the issue is the...

Výzkum vlastností materiálů pro použití ve vysokoteplotním solárním tepelně-akumulačním zásobníku / Material properties research for use in high-temperature solar thermal storage tank

Šot, František January 2018 (has links)
The use of thermal storage energy, using phase change materials appears to be an effective way to store thermal energy storage with the benefits of the high amount of energy while maintaining isothermal nature of the process. PCM methods are used in latent thermal storage systems for heat pumps, as well as in solar engineering or for temperature control in spacecraft. The past decade has extended these principles for cooling and heating in the building. There are a number of PCM systems, which operate over a wide temperature range, are used in various applications. This document includes a brief overview of the development and analysis of available thermal storage working mainly on the principle of PCM.
