The Parallel Genetic Algorithm for Multicore Systems
Vrábel, Lukáš ; Šimek, Václav (referee) ; Jaroš, Jiří (advisor)
Genetický algoritmus je optimalizačná metóda zameraná na efektívne hľadanie riešení rozličných problémov. Je založená na princípe evolúcie a prirodzeného výberu najschopnejších jedincov v prírode. Keďže je táto metóda výpočtovo náročná, bolo vymyslených veľa spôsobov na jej paralelizáciu. Avšak väčšina týchto metód je z historických dôvodov založená na superpočítačoch alebo rozsiahlych počítačových systémoch. Moderný vývoj v oblasti informačných technológií prináša na trh osobných počítačov stále lacnejšie a výkonnejšie viacjadrové systémy. Táto práca sa zaoberá návrhom nových metód paralelizácie genetického algoritmu, ktoré sa snažia naplno využiť možnosti práve týchto počítačových systémov. Tieto metódy sú následne naimplementované v programovacom jazyku C za využitia knižnice OpenMP určenej na paralelizáciu. Implementácia je následne použitá na experimentálne ohodnotenie rozličných charakteristík každej z prezentovaných metód (zrýchlenie oproti sekvenčnej verzii, závislosť konvergencie výsledných hodnôt od miery paralelizácie alebo od vyťaženia procesoru, ...). V poslednej časti práce sú prezentované porovnania nameraných hodnôt a závery vyplývajúce z týchto meraní. Následne sú prediskutované možné vylepšenia daných metód vyplývajúce z týchto záverov, ako aj možnosti spracovania väčšieho množstva charakteristík na presnejšie ohodnotenie efektivity paralelizácie genetických algoritmov.

Anisotropy and time-resolved anisotropy techniques in colloidal systems research
Holínková, Petra ; Táborský,, Petr (referee) ; Mravec, Filip (advisor)
In this diploma thesis were investigated in terms of microviscosity liquid and condensed systems composed of hyaluronan (Hya) and cationic surfactant cetyltrimethylammonium bromide (CTAB). The excitation and emission spectra, lifetime, steady-state fluorescence anisotropy and time-resolved fluorescence anisotropy of the samples were measured. First, was studied the formation of hydrophobic domains in the system Hya-CTAB at concentration of CTAB lower than its critical micelle concentration in an aqueous solution and 0.15M NaCl. It was found that in an aqueous solution small hydrophobic domains linked to chains Hya are formed. Then an increasing concentration of CTAB leads to phase separation and formation of gel. Due to the addition of NaCl then leads to the reorganization of this system and probably the formation of free micelles in the solution. Were also studied condensed phase of system Hya-CTAB-NaCl at high concentrations of surfactant during fourteen days of ageing. It was found that the microviscosity of hydrophobic domains is constant, but the microviscosity of hydrophilic parts gradually decreases.

System of day care for preschool children in the Czech Republic
Šírová, Kateřina ; Poláková, Olga (advisor) ; Barák, Vladimír (referee)
Women on maternity leave are considered one of the most vulnerable groups in the labor market. Because of their prolonged failure of the working process in connection with child care they have difficult conditions in search of employment. The system of day care for preschool children should help women to eliminate this effect. The thesis is aimed to examine the adequacy and effectiveness of the systems of day care for preschool children based on the analysis of legislation and in comparison with systems of other European states. The work also compares the sufficiency of the regions of the Czech Republic and its possible effects on female unemployment.

The Prohibition of Discrimination as a Legal Problem in the Case Law of the European Court of Human Rights
Dolejšová Kabelová, Kristýna ; Šturma, Pavel (advisor) ; Hubálková, Eva (referee) ; Hýbnerová, Stanislava (referee)
The Prohibition of Discrimination as a Legal Problem in the Case Law of the European Court of Human Rights JUDr. Kristýna Dolejšová Kabelová This dissertation thesis is focused on the examination of the prohibition of discrimination in the European system of the protection of human rights as based on the Convention for the Protection of Human Rights and Fundamentals Freedoms (hereinafter referred to it as the "European Convention"). The European Court of Human Rights (hereinafter referred to as the "European Court"), in its role as a component of this system of protection, acts as an international judicial organ that reviews individual applications concerning an alleged breach of the European Convention by a Member State. In the area of the protection of human rights such prohibition of discrimination is based on the fundamental principle of equality, and constitutes an integral part of all important international instruments for the protection of such rights, and of the modern national legal orders of states. Inevitably, however, the legal systems of modern-day states are built upon distinctions, categorizations and classifications inherent to their societies, creating unintentional opportunities for discrimination. The problem of the prohibition of discrimination consists in delimiting the...

Fictional political mirroring in Two novels by Vladimír Nabokov
Šindelářová, Martina ; Quinn, Justin (advisor) ; Roraback, Erik Sherman (referee)
The focus of this thesis is to closely analyze two novels by Vladimir Nabokov, namely Invitation to a Beheading and Bend Sinister, and on the basis of close reading as well as detailed examination of critical literature enlighten the circumstances of their creation in the course of author's life and the influences and experiences that might have imprinted in the novels. Although validity of biographical approach may be subjected to question, it proves to be a rather insightful approach concerning the central topic of the thesis and it also provides wider perspective for more accurate understanding of the novels, as it directs the reader from politics towards more philosophical and aesthetical concerns. The thesis should also summarise the main points of Nabokov's artistic theory and clarify what was the main concern of Nabokov's literary works. Invitation to a Beheading, one of the last works Nabokov wrote in his mother tongue, a "dystopian fable" which appeared for the first time in a Russian émigré magazine Sovremenniya Zapiski in 1938, follows the last days of Cincinnatus C., a prisoner sentenced to death for his deviation from the common transparency of his fellow citizens in a world which is a grotesque parody of an absurd political regime, but at the same time this exaggerating portrayal depicts the...

Use of ethology with technology of milking robot
SCHESTAUBEROVÁ, Markéta
If we require higher yields from dairy cows, we have to provide them with good living conditions. It is necessary to know their natural behaviour and give them a chance to show it. One of the possibilities to make better living conditions to dairy cows seems to be an introduction of the automatic milking system to cowshed. The aim of this diploma thesis is to evaluate basic behaviour of dairy cows during all day in two cowsheds with automatic milking system, and to create a data file of dairy cows in two cowsheds with breeding of two different kinds of cattle - Czech Spotted cattle and Holstein dairy cows, and two different automatic milking systems ? Lely Astronaut and DeLaval. The results were evaluated by particular applicative statistics methods and the differences between the breeds and types of robots were compared. The thesis concerns three ethological observations in 2010 and 2011 which took place in Agricultural Cooperative Kluky near Písek, where Holstein dairy cows is bred and automatic milking system Lely Astronaut is used, and also three ethological observations in 2009 on a family farm in Chlumeček near Křemže, where Czech Spotted cattle is bred and automatic system DeLaval is used. The Holstein dairy cows spent feeding from 3,4 to 3,9 hours per day and Czech Spotted cattle spent feeding from 5,6 to 6,3 hours per day during all observation. In category standing were included: plain standing, standing with other activities (standing ? drinking, standing ? urinating, standing ? defecating, standing ? comfort behavior) and milking in robot. The Holstein dairy cows and Czech Spotted cattle spent standing from 5,6 to 6,3 hours per day. In the category of lying, significant differences were found. The Holstein dairy cows spent lying from 14,1 to 15 hours per day. The Czech Spotted cattle spent lying from 11,6 to 12 hours per day. Last observed category was moving. The Holstein dairy cows spent moving 0,4 hours per day and the Czech Spotted cattle spent moving from 0,9 to 1,1 hours per day. The quantity of milk of Holstein dairy cows per lactation was 6701 kg in average with quantity of protein 229,694 kg with content of 3,375%. The quantity of milk of Czech Spotted cattle was 4690 kg with quantity of protein 159,33 kg. The length of insemination interval of Holstein dairy cows was 71,35 days in average and service period was 159,97 days in average. The length of insemination interval of Czech Spotted cattle was 130,49 days in average and service period was 159,97 days in average. The data was processed with the help of Microsoft Excel and Statistica 10.

Treatment of rheumatoid arthritis
Šumpichová, Veronika ; Hrdina, Radomír (advisor) ; Herink, Josef (referee)
Summary: Approximately 1% of population around the world is currently suffering of rheumatoid arthritis. It is an autoimmune chronical inflamatory disease that affects joints. However, usually also other tissues or systems are affected. The crucial is an oblique immune process when the body is responding to the unknown factor by creating antibodies and destroying itself. The development of the disease can be affected by combination of genetic predisposition and until now non-indetified agent or agents. Moreover, the general influence on disease have female gender, positive family history, effect of silicium compounds or consumption of more than three cups of coffee a day. Originally used concept of pharmacotherapy was aimed at slow and non-agressive therapy based on serial distribution of anthirheumatic medicines. The treatment was treating the disease symptomatically. However the symptoms have dissapeared, the progress of the disease was not decelerated. The crucial change in the pharmaceutical field of research has appeared in prescribing new medicines and within the change of pharmacotherapeutical style; these changes has been affected by high number of side effects of the previous treatment. Aim: To summarize the latest trends in pharmacotherapy of RA, esspecially in last ten years. Conclusion:...
