Study of Electrophysiological Function of the Heart in Experimental Cardiology
Ronzhina, Marina ; Tyšler, Milan (referee) ; Halámek, Josef (referee) ; Kolářová, Jana (advisor)
Srdeční poruchy, jejichž příkladem je ischemie myokardu, infarkt, hypertrofie levé komory a myokarditida, jsou v experimentální kardiologii obvykle studovány na modelu izolovaného srdce. Kritéria pro detekci srdečních poruch však nejsou pro zvířecí modely standardizována, což komplikuje srovnání a interpretaci výsledků různých experimentálních studií. Obzvlášť složitá situace nastává při současném výskytu několika patologických jevů, jejichž vzájemná součinnost komplikuje rozpoznání jejich individuálních účinků. Korektní posouzení stavu srdce vyžaduje také zohlednění mnoha faktorů spojených s akvizicí dat. Tato práce je věnována kvantitativnímu hodnocení elektrofyziologických změn způsobených globální ischemií myokardu. Vliv ischemie byl hodnocen pro fyziologická srdce a srdce se zvětšenou levou komorou a dále pro srdce nabarvená napěťově-citlivým barvivem di-4-ANEPPS. Přestože jsou oba fenomény často zastoupeny v animálních studiích, nebyl dosud popsán jejich vliv na manifestaci ischemie v elektrogramech (EG), ani nebyl kvantifikován jejich vliv na přesnost detekčních algoritmů pro identifikaci ischemie. Práce shrnuje kvantitativní změny srdeční funkce vyvolané ischemií (v normálních podmínkách, při hypertrofii levé komory, a při administraci barviva) založené na hodnocení EG a VKG parametrů. Dále práce obsahuje rozbor důležitých aspektů akvizice záznamů, jako je umístění snímacích elektrod, způsob výpočtu deskriptorů z EG a VKG (s použitím výsledků manuálního rozměření záznamů, nebo bez něj) a identifikace okamžiku vývoje ischemie v preparátu. Nedílnou součást práce tvoří návrh, realizace a ověření metod pro automatickou detekci ischemie v experimentálních záznamech. Výsledky práce dokazují, že dosažení opakovatelných a věrohodných výsledků je podmíněno zohledněním všech výše uvedených faktorů souvisejících jak se stavem srdce, tak s metodikou záznamu a analýzy dat.

The central bank and its function in the economy
Guth, Karel ; Kopecká, Lenka (advisor) ; Soukup, Alexandr (referee)
The following thesis describes the importance of the central bank in the states economy and its position in the structure of the banking and financial system. It deals with its monetary policy and functions such as the role of the state bank, issuance activity or the regulation and supervision of commercial banks. The theoretical part is concluded by describing the Maastricht convergence criteria, which is built on in a questionnaire survey of the practical part.
The practical part is divided into two sections. The first is focused on the exchange rate as a monetary tool of the Czech National Bank. It attempts to compare how successfully CNB has achieved its predictions from 2014 (the year when the foreign exchange interventions were initiated). The second section contains an interpretation of the results from the survey, with the aim of identifying the attitudes of Czech citizens towards adopting the euro currency. Subsequently, testing of a statistical hypothesis for contingency between selected issues was performed and connections within the columnar frequency of the contingency tables were observed and picked out.

Network attached storage
Pavlíček, Ladislav ; Vokoun, Tomáš (advisor) ; Pavlík, Jan (referee)
The thesis explores the subject of data storage options, focusing on Network Attached Storage (NAS) solution and its potential target users. The theoretical part of the thesis reviews the overall data storage solutions used in the past, compared to the current ones. The further description of NAS is provided, highlighting its specifications and possibilities for use. In addition, the analysis of different methods of data storing on a hard disc drive is conducted and resulting data reliability is examined and assessed. The aim of this bachelor thesis is to recommend NAS for suitable user groups based on their needs and habits. To gather relevant data and identify those characteristics, the research method of survey based data collection is being used. As a result, the particular potential user group for NAS, currently unaware of its benefits and uses, is identified. This group is characterized by its online content use and consumption patterns in areas of video and music content consumption, photo sharing, file backing-up habits, cloud usage, etc. Furthermore, the thesis expands on the potential benefits for those users and provides practical suggestions for use in regard to their identified needs. In the last part of the thesis, collected survey data are being compared to the related national survey data provided by the Czech Statistical Office. The concluding analysis reveals a trend of decreasing interest between year 2015 and 2016 for using cloud data storage solutions in general, mainly in terms of storing and sharing of photos, movies and music. Finally, the limitations of survey data collection are being discussed, focusing on particular internal and external factors which could have influenced the survey results.

The effect of bailiff territoriality on the reclamation of receivables, the length of debt recovery and other aspects of court-ordered distraints
Plaček, Jan ; Smrčka, Luboš (advisor) ; Belás, Jaroslav (referee) ; Hučka, Miroslav (referee)
The area of individual reclamation of receivables in the form of court-ordered distraints has undergone significant changes since the year 2000. The initial practice, when the claims used to be enforced directly by judicial officers, proved to be largely ineffective and with difficult to apply. The Ministry of Justice has responded by adopting an amendment to the Act (Act no. 120/2001 Coll., on bailiffs and executor activities), which introduced the independent bailiff offices. Then, the law itself understood the bailiff authorities as a separate entrepreneurs. Currently, in the Czech Republic, there can be seen the distribution of the market with distraints according to the Pareto rule. Approximately 20% of bailiff offices manage over 80% of distraints. It is obvious that this is an unsatisfactory condition for the majority of bailiff offices. In response to this fact, the Czech Chamber of Bailiff offices calls for the introduction of territoriality, which would eliminate by law the market environment from the market with distraints and every single bailiff office would have a stable allocation of distraint proceedings. The analysis carried out clearly shows that there are significant differences between bailiff offices in terms of speed and in success of the debt recovery. The actual demand for the introduction of territoriality would not merely be a reallocation of the market with distraints. Putting it into a practice would greatly influence the transactional costs of business and non-business entities in the Czech economy. The thesis comprehensively describes the issue of territoriality and quantifies how much the debt collection will decrease in case of its introduction. In the conclusion, an alternative draft is formulated, which might, according to the author, allow effective regulation and supervision of the activities of bailiffs' offices without compromising the inherent efficiency of the reclamation of receivables in terms of market environment.

Design of search engine for modern needs
Maršálek, Tomáš ; Palovská, Helena (advisor) ; Strossa, Petr (referee)
In this work I argue that field of text search has focused mostly on long text documents, but there is a growing need for efficient short text search, which has different user expectations. Due to this reduced data set size requirements different algorithmic techniques become more computationally affordable. The focus of this work is on approximate and prefix search and purely text based ranking methods, which are needed due to lower precision of text statistics on short text. A basic prototype search engine has been created using the researched techniques. Its capabilities were demonstrated on example search scenarios and the implementation was compared to two other open source systems representing currently recommended approaches for short text search problem. The results show feasibility of the implemented prototype regarding both user expectations and performance. Several options of future direction of the system are proposed.
