Pro nalezení ekvivalentních náhrad kompozitních materiál· p°i inverzn í úloze je v práci vyuoito globálních optimalizaLních metod.The work is aimed to propose a methodology for creating an equivalent of composite materials used for construction of small aircraft. Such equivalent should enable to create numerical models of small aircraft in the simulation of precertication EMC tests for aircraft resistance against the lightning. Eliminating situations threatening the aircraft and passengers in the initial steps of the design will allow savings in production costs and contribute to the safety of air transport. In order to nd the equivalent of composite materials, global optimization methods will be used.

The Complete Analytical Solution of the TDOA Localization Method

This article is focused on the analytical solution of a TDOA (Time Difference of Arrival) localization method, including analysis of accuracy and unambiguity of a target position estimation in 2D space. The method is processed under two conditions - sufficiently determined localization system and an overdetermined localization system. It is assumed that the TDOA localization system operates in a LOS (Line of Sight) situation and several time-synchronized sensors are placed arbitrarily across the area. The main contribution of the article is the complete description of the TDOA localization method in analytical form only. It means, this paper shows a geometric representation and an analytical solution of the TDOA localization technique model. In addition, analyses of unambiguity and solvability of the method algorithm are presented, together with accuracy analysis of this TDOA technique in analytical form. Finally, the description of this TDOA method is extended to an overdetermined TDOA system. This makes it possible to determine and subsequently optimize its computational complexity, for example increase its computational speed. It seems that such a description of the TDOA localization technique creates a simple and effective tool for technological implementation of this method into military localization systems

Pre-Design of Multi-Band Planar Antennas by Artificial Neural Networks

In this communication, artificial neural networks are used to estimate the initial structure of a multiband planar antenna. The neural networks are trained on a set of selected normalized multiband antennas characterized by time-efficient modal analysis with limited accuracy. Using the Deep Learning Toolbox in Matlab, several types of neural networks have been created and trained on the sample planar multiband antennas. In the neural network learning process, suitable network types were selected for the design of these antennas. The trained networks, depending on the desired operating bands, will select the appropriate antenna geometry. This is further optimized using Newton's method in HFSS. The use of the neural pre-design concept speeds up and simplifies the design of multiband planar antennas. The findings presented in this paper will be used to refine and accelerate the design of planar multiband antennas

Language Management of Secondary Education Teachers of Czech and Their Contribution to Forming the Standard Czech

This thesis analysis in social practise the Language Management Theory - it deals with pedagogical activity of Czech language teachers at secondary schools, based on corrections of writen language tests. The goal of this paper was to find out whether the norm of czech standard language which is contained in codices correspond with the norm that is presented by teachers. This thesis uses modern metdological approaches from the sociolinguistic sphere, especially the method of so called 'Follow-Up Interview'. It also uses the concept of the Social Power Field by Ulrich Ammon and the Language Management Theory by J. V. Neustupný as general methodological basis. As the source of information served authentic tests which has been filled by fifty students of a secondary school a and then corrected by eight czech language teachers. Other sources were Follow-Up Interviews with the teachers and questionnaires. On the basis of these sources the Language Management Theory was researched and also the idea of the teachers about the norm of standard language. This idea was compared to the opinions of other three instances of the Social Power Field. In cases there was something unclear the information were completed from the Follow-Up Interviews. The research has proved that in the most cases the norm presented by teachers..

Symbols in Short Stories of Czech Romanticism

Tématem této bakalářské práce jsou symboly v české romantické próze, jejich izolování, třídění a systematizace podle metody dané monografií M. Exnera Struktura symbolična v pohledu psychoanalytické literární vědy. Práce také shrnuje specifika české romantické prózy a její typické zástupce. Jsou definovány pojmy romantismus, preromantismus a biedermeier, které jsou uvedeny do vzájemného vztahu na základě výskytů symbolů. Hlavním záměrem bylo prokázat osvojení dané metody a porozumění problematice symbolů. Pro přehlednost byly symboly zaneseny do tabulek a z nich byly vyvozeny závěry.The subject of this Bachelor´s thesis are symbols in the Czech prose of Romanticism, their isolation, classification and systematization in accordance with the method indicated in the monograph The Structure of Symbolism by Milan Exner. The work also introduces specifics of the Czech prose of Romaniticism and its representatives. The terms Romanticism, Preromanticism and Biedermeier are defined as well as their relationships based on the occurrence of symbols. The main purpose was to prove an acquisition of the method given and to understand the problematics of symbols. In order of clarity, the symbols were registered in tables, out of which the conclusion was made

The role of the word of God in christian spiritual life

RÉSUMÉ The problem of word of God in spiritual life of the Christian The topic of this work is Holy Scripture - Word of God - from the sight of spiritual life. What is the Bible for Christian? How it can be influent for our daily life? How the Church understood the Holy Scripture? Theoretic resource of this work is teaching of the Second Vatican council about word of God, especially constitution "Dei verbum". There were basic ideas of this teaching formed in Century 19th by biblical movement, which made an effort for more serious thinking in the faith through the come back to the source of the Holy Scripture. The principal points of the teaching of the Second Vatican council about word of God are followed: "The Scripture" is revelation of the God. The God reveals us in the Scripture his plan of the salvation which culminate by the coming the Son of God into the world. The Holy Scripture is inspired word of living God therefore the church has it in honest and love. The constitution "Dei verbum" speaks the table of the word of God in the same level as the eucharist. Through the Scripture we meet the God that is why it is for faithful "food" on the way to the salvation. The teaching of the Council had opened the way to the study of the Scripture based on the scientific level. It also encouraged lay people to..
