Predikce sekundární struktury RNA sekvencí / Prediction of RNA secondary structure

Klímová, Markéta January 2015 (has links)
RNA secondary structure is very important in many biological processes. Efficient structure prediction can give information for experimental investigations of these processes. Many available programs for secondary structure prediction exist. Some of them use single sequence, the others use more related sequences. Pseudoknots are still problematic for most methods. This work presents several methods and publicly available software and the implementation of minimum free energy method is described.

Souvislost charakteristik tazatele a odpovědí respondenta při face to face interview / Connection between charasteristics of an interviewer and respondet's answers in face to face interviews

Strnadová, Mirka January 2015 (has links)
This diploma thesis shows a connection between an interviewer's demographic characteristics and a respondent's answers during a face-to-face interview. The analysis uses the American data from General Social Survey and the Czech data from CVVM. The monitored variables are sex, age, education and the size of place. On the ground of the theory of interpersonal communication, social distance and stereotypical answers to certain questions the following questions were chosen to be analysed: the willingness to have certain group of people as neighbours, opinions on marihuana, the death penalty, abortions and homosexuals. The analysis proves that the interviewer's demographic characteristics do influence the answers to some of these questions. However there is no set of rules that could prove which particular characteristics would influence which particular questions. The methods used in this thesis are correlational analysis, binary logistic regression and an advanced mixed models analysis. The next part consists of a qualitative research, which uses a fictional face-to-face interviews and following cognitive interviews with respondents. This part shows the importance of the actual question because when the respondent answers a certain question for the first time he is more likely to be influenced by the...

Harm reduction strategie užívání konopných drog z pohledu jejich uživatelů / Harm reduction strategies of cannabis drugs use from the point of view of their users

Scherberová, Jana January 2021 (has links)
Background: Cannabis drugs are the most used illicit drug in the Czech Republic. About 1,78 million people use cannabis, most of them are young people aged 15-34 years (Mravčík et al., 2020). Use in the young age, regular and intensive use of large amounts of cannabis is associated with the negative impact on health and life of users. Previous studies have described the harm redcution strategies, less is known about relative occurrence of the hram reduction stategies, especially in the czech environment. Aims: The aim of the study was to investigate what kind of harm reduction strategies are used by cannabis users. Methods: The research was conducted as a quantitative study. This mapping study was aimed to describe the behaviour of cannabis users in relation to use of the harm reduction strategies, and to explore the relative occurrence of these strategies. As a method of data collection was used a questionnaire survey. Results: Most frequently emerged harm reduction strategies among cannabis users are in relation to the effects of use on physical health. Most of these strategies focus on minimising the harms associated with smoking cannabis, particularly marijuana cigarettes. Mental health strategies are based on the concept of set, where users often do not use if they observe negative feelings...

Speciální třídy Booleovských funkcí s ohledem na složitost jejich minimalizace / Special Classes of Boolean Functions with Respect to the Complexity of their Minimization.

Gurský, Štefan January 2014 (has links)
In this thesis we study Boolean functions from three different perspectives. First, we study the complex- ity of Boolean minimization for several classes of formulas with polynomially solvable SAT, and formulate sufficient conditions for a class which cause the minimization problem to drop at least one level in the polyno- mial hierarchy. Second, we study a class of matched CNFs for which SAT is trivial but minimization remains Σp 2 complete. We prove that every matched CNF has at least one equivalent prime and irredundant CNF that is also matched. We use this fact to prove the main result of this part, namely that for every matched CNF all clause minimal equivalent CNFs are also matched. Third, we look at propagation completeness - the property of a CNF that says that for every partial assignment all entailed literals can be discovered by unit propagation. We can extend every CNF to be propagation complete by adding empowering impli- cates to it. The main result of this section is a the proof of coNP completeness of the recognition problem for propagation complete CNFs. We also show that there exist CNFs to which an exponential number of empowering implicates have to be added to make them propagation complete.

Využití informačních technologií pro manažerské sledování efektivity času a minimalizaci nákladů / Information technologies enabling managerial time tracking and cost reduction

Dědek, Lubomír January 2008 (has links)
Time tracking means to record and analyze costs in relation with business output. Managerial time tracking can be characterized as a tool that links working-time recording with planning, approving, rating, billing, invoicing, etc. This thesis deals with theoretical consequences and facts of time tracking approaches, and with practical application of these approaches with the usage of IT time tracking tools. There are described various alternatives of time tracking systems and characterized automatization of business processes with the focus on time tracking business process.

Vysokorychlostní vrtání plechů z hliníkových slitin / High speed drilling of aluminium plates

Pilný, Lukáš January 2011 (has links)
Optimalizace procesu vrtání kovových materiálů vyžaduje minimální tvorbu otřepů a jednotný vzhled vrtaných děr. Cílem práce bylo pochopit roli různých klíčových faktorů, jako řezných podmínek, způsobu upnutí obrobku a geometrie vrtáku, na tvorbu otřepů při vrtání 2 mm plechů tvářené hliníkové slitiny Al99.7Mg0.5Cu-H24, za použití vrtáků o průměru 1,6 a 2 mm, pro dosažení minimalizace tvorby otřepů a zajištění jednotnosti získaných povrchů pro velký počet vrtaných děr v obrobku. Tohoto cíle bylo dosaženo provedením 3 experimentálních testů. První experimentální test byl proveden za účelem sledování vlivu řezné rychlosti a posuvu za otáčku, jakožto rozpoznaných řezných parametrů nejvýznamněji ovlivňujících tvorbu otřepů, na výsledné velikosti vzniklých otřepů a jednotnosti vrtaných děr. V druhém experimentu byl zkonstruován vakuový upínací přípravek, za účelem upnutí vrtaného hliníkového plechu a omezení prostoru pro tvorbu otřepů na výstupní straně vrtání na obrobku, a jeho vlivu na tvorbu otřepů bylo vyhodnoceno. V třetím testu byl vyhodnocen efekt rozdílných geometrií vrtáků na tvorbu otřepů, spolu s dosaženou jednotností vrtaných děr. Výsledky z prvního experimentu prokázaly, že výška a tloušťka otřepů je redukována na obou stranách vrtaného plechu za použití vyšších řezných rychlostí. Při použití vyšších posuvů byla viděna zvětšující se výška a tloušťka otřepů na obou stranách vrtání, s výjimkou výšky otřepů na vstupní straně vrtáku do obrobku, která byla minimálně snížena. Druhý experiment prokázal, že vhodně konstruovaný vakuový upínací přípravek může významně omezit vznik otřepů na výstupní straně vrtáku z obrobku. V třetím experimentu, za použití 3 břitého vrtáku a vhodně konstruovaného vakuového upínací ho přípravku, bylo dosaženo eliminace tvorby otřepů z obou stran vrtaného plechu, společně s naplněním požadavků na jednotný vzhled vrtaných děr a vysoké výrobní produktivity. Takovýto optimalizovaný proces, bez nutnosti použití přídavné operace na odstranění vzniklých otřepů, poskytuje významnou redukci výrobních nákladů. Mimoto jsou poskytnuta doporučení pro další výzkum k dosažení zlepšení ve výrobě.
