The simulation of biometric protection systems working on the face recognition principle
Dubský, Milan ; Rampl, Ivan (referee) ; Atassi, Hicham (advisor)
The aim of this work is to realize a system in the Matlab-Simulink environment, which will be able to detect and recognize the human face from the input image. The created model will actually simulate the biometric security systems working on the principle of face recognition. The work is divided into two parts. In the first part, several methods for face detection from image are described. We focused on the symptomatic oriented and color segmentation methods. The pattern matching method is also described and implemented; the advantage ofthe pattern matching that it can be used either for face detection or face recognition. The second part of this work contains a description of the face recognition. Where PCA (Principal Component Analysis) are used for this task, this part of the work also includes experimental results of tests performed on our methods.

Applications of Fibonacci numbers in economy - Elliott Wave Principle
Rusyniak, Martin ; Karásek, Jiří (referee) ; Klaška, Jiří (advisor)
The Elliott wave principle, as a technique for prediction of price movements, combines knowledge of Fibonacci numbers, golden ratio and crowd psychology. This method replaces price fluctuations with waves, amongst which it is finding relation to the golden ratio. In the introduction of this bachelor thesis, we are going to have a look at Fibonacci, his integer sequence and theoretical description of the Elliott wave principle. The core of this thesis is explanation of basic strategy on five-wave pattern and later, swing breakout strategy and 3-swing pattern. All of these strategies are presented on real-world examples with explanation of analogy and nuances. These strategies were explained as factual usable algorithms with clarification of all properties. Concept of algorithm for the application of breakout strategy and its flowchart is included in matching chapter. After that follows insight into problematic of spirals as a method uncovering another options for use of the golden ratio for analysing price movements.

Problems of Czech morphology in selected handbooks
Prohorenco, Dmitrii ; Hrdlička, Milan (advisor) ; Holub, Jan (referee)
Czech language is inflective, that is one ending/suffix cumulates many categories. Many words (especially nouns, verbs and adjectives) have many forms. There are seven cases, fourteen basic types for nouns, five verb conjugation classes, ten parts of speech in czech. Verbs have categories of voice, aspect, person and tense. Nouns have gramatic categories of number, case and gender. There is a variety of irregularities, dual forms etc. in czech. Czech orthography is complicated when compared to croatian or finish, but is relatively simple when compared to french or english. One can say that czech orthography is phonological, but it takes into consideration also morphology and etymology. Czech is spoken primarily in Czech republic. There are some czech minorities in Australia, Argentina, Romania and USA. Czech is quite popular for foreigners to study, also it is spoken only by aproximately 12 mln. of people. The czech word order is different from the word order of english or french, that is relatively restrictive. The czech word order is on the other hand relatively free. Often all the permutations of words in a clause are possible. The concept of czech word order introduced Vilem Mathesius - the co-founder of Prague Linguistic Circle. Usually there exists the basic word order. Observing discourse patterns,...

Forearc deformation and strain partitioning during growth of a continental magmatic arc: the northwestern margin of the Central Bohemian Plutonic Complex, Bohemian Massif
Dragoun, František ; Žák, Jiří (advisor) ; Ulrich, Stanislav (referee)
This doctoral thesis is focused on analysis of tectonic deformations associated with the Late Devonian subduction followed by the Early Carboniferous continental collision of the Saxothuringian and overriding upper-crustal Teplá-Barrandian units, which led to the growth of a large magmatic arc (the ~354-337 Ma Central Bohemian Plutonic Complex) in the central part of the Bohemian Massif. Far-field tectonic forces resulting from the collision produced ~WNW-ESE to ~NW-SE regional shortening across the forearc upper crust above the subduction zone; the shortening was accommodated by predominantly top-to-the-ESE tectonic transport along the southeastern flank of the Teplá-Barrandian unit. Approaching the magmatic arc margin, the regional structural pattern changes and exhibits significant acrossand along-strike variations interpreted as a result of strain partitioning, where the Saxothuringian/Teplá-Barrandian convergence interacted in different ways with the intruding magma pulses. Around the voluminous, northeasterly ~354 Ma Sázava pluton the principal shortening was at high angle to the forearc-facing intrusive contact and the host rocks were significantly thermally softened. The regional top-to-the-ESE tectonic transport converted here into arc-parallel ductile flow within the structural aureole...

The process of compilation and accepting of the civil code during the Meiji period
Kraus, Jan ; Sýkora, Jan (referee) ; Labus, David (advisor)
This work concerns itselť with o ne oť the aspects oť the modernization oť Japan during the Meiji Era (1868-1912), the establishment oť a Civil Code based on western lega! princip les, in a broad context oť the historical and socio-political situation of the said period. First, it explores the state oť lega! knowledge in Japan at the end of the previous historical period, the Tokugawa Era. As a result of the development during the centuries prior to that, it may be said that the Japanese view oť law became to be such that the law was overshadowed by the traditional pattern oť a rigid social structure, preferring over law the mutual relations among the people living in such a system. Being ťorced to cancel her isolation policy by an extensive outside pressure ťrom the worlďs powers, Japan starts to strive for a general modernization. The s o called U nequal treaties established in the last years of the rule oť the Tokugawa shogunate between Japan and several countries set it to an inferior position, and this situation continued unchanged in the ťollowing Meiji period. One of the prerequisites for the revision of these treaties was the establishment of a western-like lega! system with the Civil Code as one oť the important Codes of Law. However, the principles on which the Japanese and the western lega!...

The Media Image of Visual Arts in Czech Television
Švarcová, Barbora ; BENDOVÁ, Helena (advisor) ; POSPISZYL, Tomáš (referee)
The thesis consists of a context and textual analysis of Artmix, a TV show dedicated to visual arts, while touching on other relevant programs on Czech TV. The results of these analyses are then brought into theoretical setting primarily using the philosophical and social concept of the Field of Power as defined by Pierre Bourdieu in his book Rules of Art.
Principal themes, interspersing throughout the text, are the limits of reflections of visual arts through TV screen and hidden interpretational patterns applied to visual arts through its media image. Furthermore there is an additional issue of traditional notions of an artist existing within our society, weighed down by history, or the quest for the ideal format of a TV show reflecting visual arts.
