Structure and approximation of real planar algebraic curves
Blažková, Eva ; Šír, Zbyněk (advisor)
Finding a topologically accurate approximation of a real planar algebraic curve is a classic problem in Computer Aided Geometric Design. Algorithms describing the topology search primarily the singular points and are usually based on algebraic techniques applied directly to the curve equation. In this thesis we propose a more geometric approach, taking into account the subsequent high-precision approximation. Our algorithm is primarily based on the identification and approximation of smooth monotonous curve segments, which can in certain cases cross the singularities of the curve. To find the characteristic points we use not only the primary algebraic equation of the curve but also, and more importantly, its implicit support function representation. Using the rational Puiseux series, we describe local properties of curve branches at the points of interest and exploit them to find their connectivity. The support function representation is also used for an approximation of the segments. In this way, we obtain an approximate graph of the entire curve with several nice properties. It approximates the curve within a given Hausdorff distance. The actual error can be measured efficiently. The ap- proximate curve and its offsets are piecewise rational. And the question of topological equivalence of the...

The Merger of Třeboň Municipal Spas - An Assess
BLAŽKOVÁ, Eva
The aim of this bachelor thesis is an evaluation of a fusion of the Municipal Spa Třeboň Ltd. The thesis is divided into a theoretical and practical part. The theoretical part is focused on an introduction of the issue, the characteristics and aims of a project of restructulisation of the fused spa companies. This part defines the theoretic-methodological outcomes necessary for processing the practical part. Furthermore, the town of Třeboň is described as well as the historical facts about a development of balneology in Třeboň that confirm technological justification and thus also prospects of balneology there. There is also an outline of the newly established Slatinné lázně Třeboň (Peat Spa Třeboň Company Ltd.), providing balneological services, spa capacity and economic situation of the Spa before and after the fusion. The practical part is based on a secondary data analysis, where the data are from 2014-2016 and from 2017 which is after the fusion, aimed at the spa results numbers of clients, their structure according to obtained services as well as an average length of their stay. Furthermore, the economic data describing the company results which are taken from accessible sources and straight from the Peat Spa Třeboň Company Ltd. For a fusion evaluation, also a quantitative and qualitative research was implemented, aimed at obtaining an insight into a social reality through the questionnaire research. Also the data obtained from a client feedback system "AskNow" gathered by the company were used. The following part of the thesis is based on a statistic confirmation of the real capacity and especially of economic development while adhering to a general progress of technical and medical standards that confirm the processed data by SWOT analysis. The bachelor thesis attempts to back the justification of the fusion also from the point of view of the Czech Medical Balneology which is based on a necessity of more financial sources than those provided by the state medical care. This necessity of financial support is available for a subject strong in economy and capacity. The Peat Spa Třeboň Ltd. has become such a subject after the implemented fusion, with a perspective of further development and gaining a strong position from the point of view of general technological and economic activities among the leading spa institutions in the Czech Republic, based on the patients´ interest in the procedures and services of the Municipal Spa Třeboň.

Protection of a supplier against conduct of the contracting agency in public tenders
Blažková, Eva ; Plíva, Stanislav (advisor) ; Liška, Petr (referee)
Protection of a supplier against conduct of the contracting agency in public tenders The aim of this thesis is to analyze the legal instruments by which suppliers can defend against unlawful practises of contracting entity. The reason of choosing this theme is my deep interest in this sphere. Ever year, more than eight thousand tenders are announced in the Czech Republic. There are more than fifteen thousand contracting authorities. The public sector expends more than 600 billion Czech crowns on public procurement every year. The acting of subjects involved in the procurement proces is often unlawful. It is therefore necessary to set the legal framework of competition for public contracts so that it will be ensured prevention the unlawful procedures of subjects affecting the procurement process and ensure the most efficient spending of public funds. This thesis consists of four chapters. The first concerns the most important principles associated with public procurement. There are also examples of practical reflection of these principles to various statutory provisions. The second chapter is devoted to the juridical institut of objections to acts of the contracting authorities. Chapter three is focused on the public procurement supervision held by the Office for the Protection of Competition. The...

Eco-Counselling of Industrial Distressed Area
Blažková, Eva ; Rynda, Ivan (advisor) ; Kulich, Jiří (referee)
The subject of my Diploma work on the theme "Eco - Counselling of industrial, distressed area" is the analyse of selected Eco - Counselling places located in the Czech Republic and creation of general models of those. The results of this analyze are followed in the next part of this work. Subsequently the teoretical model of Eco - Counselling for the region of Chomutov is proposed. For that purpose, the study of the conditions and characteristics of this locality is utilized. As for this work, there are following investigative questions: 1) Which models of Eco - Counselling provided in Czech Republic are free of charge? 2) Which model of Eco - Counselling place corresponds with the demand of Chomutov region? (concerning the other characteristics of the region). The essential method for this work is Case Studies, which draw from the methods of anylysis of the Annual Reports. The benefit of this work is the typology of Eco - Counselling practice in the Czech Republic and subsequently it stresses and explains the relation with the particular region (certain types correspond with certain environment). As well the work proposes dynamic model of Eco - Counselling for the Chomutov region.

Entry of the movie service Netflix into the Czech movie market
Kawulok, Filip ; Hanzlík, Jan (advisor) ; Blažková, Eva (referee)
This thesis will focus on movie distribution via internet, especially on American movie service Netlix and its impact on recent entry to Czech movie market. In the theoretical part will be processed summary of past and recent movie distribution windows. In the practical part will be processed survey, which purpose will be to find out how did Netflix succeed to get into awareness of consumers of the film culture in the Czech republic.

The flange gasket modification of SG VVER 440 primary collector
Blažková, Eva ; Martinec, Jiří (referee) ; Šen, Hugo (advisor)
The aim of this thesis is to address issues concerning the sealing of the lid for the primary collector within the steam generator (SG) of the nuclear power plant VVER 440. These steam generators are sealed in the original design by nickel rings. Modifying the existing method of sealing by a new type of sealing material, primarily from expanded graphite, can significantly reduce the pressure in the sealing surface and also stress in bolts and flanged joints. The new solution of sealing between the joint of collector and the lid should extend the life of joints and thus the nuclear and technical safety. The text is divided into the theoretical and computational part. A principle of the SG, the SG design, and a description of the joint and lid are mentioned in the theoretical part. The computational part shows calculations of the new joint, the original one, and comparison of both solutions in terms of technical and nuclear safety. The work contains drawing of the new joint.
