Naplňování úkolů civilní ochrany na území České republiky z pohledu mezinárodního práva / Fulfilling the tasks of civil protection in the territory of the Czech Republic from the perspective of international law

ŠIMKOVÁ, Lucie January 2014 (has links)
The theoretical part of the thesis explains several terms from the area of civil protection, such as civil protection, international humanitarian law, extraordinary and crisis event, and describes the historical development of civil protection in an international environment and in the territory of today's Czech Republic. The thesis also characterizes international institutions while addressing some of them, namely ICRC, UN, NATO and EU, in more detail. It describes the history, characteristics and organization structure of international institutions, as well as involvement of the North Atlantic Alliance and European Union in civil emergency planning. In terms of the Czech Republic, the thesis examines particularly how the population protection is organized in its territory. Last but not least, the thesis specifies international rules of law connected with civil protection, rules of law of the NATO addressing civil protection, rules of law of the EU addressing civil protection and Czech rules of law addressing population protection. The objective of thesis is to compare and evaluate fulfilment of tasks of the Czech and international legislation in the area of civil protection. The thesis will also serve as a study material for students of the branches "Civil Emergency Preparedness" and "Population Protection with Specialization in CBRNE" and as a supporting material for the regional authority and the authorities of municipalities with extended competence. The first section of the research part of the diploma thesis examines selected rules of law of civil protection of the Czech Republic , NATO and EU and, last but not least, Geneva Conventions. In 2013 the new Population Protection Policy for the period until 2020 with an outlook until 2030 entered into effect in the Czech Republic, based on which six areas of population protection were created. A new document of civil emergency planning of NATO is the 2014-2017 Political Guidance of CEP. Decision No. 1313/2013/EU on a Union Civil Protection Mechanism has been used as the principal document for civil protection within the EU since 1. 1. 2014. These three rules of law are the main documents used for the comparison and evaluation of fulfilment of tasks of the Czech and international legislation in this thesis and are examined in more detailed. The last of the documents mentioned in this part of the thesis are the Geneva Conventions, and the thesis examines particularly their embodiment in the Czech legal regulation. At the end of this part there is a summary table that matches Czech rules of law to international rules of law in individual areas. The rules of law of the EU and NATO constitute a superstructure above the rules of law of their Member States and cannot be directly compared; however, it is possible to determine whether the Czech rules of law comply with them. The Geneva Conventions have been embodied in the legal order of the Czech Republic, and other provisions thereof have been implemented through other Acts. As far as NATO is concerned, cooperation takes place particularly between organizations in individual cases. Cooperation and coordination between EU and Member States do not interfere in the primary responsibility for the protection of population, environment, property and cultural heritage of the Member States within their own territories. The Decision on the Mechanism also does not concern mutual rights and obligations of Member States that are embodied in bilateral or multilateral treaties in the area of civil protection. At the conclusion, the thesis proposes certain changes and amendments to the Czech rules of law, which could improve civil protection in the territory of the Czech Republic and facilitate interconnection with the international environment, which has not been working yet as it is supposed to since the new Population Protection Policy has not been in full compliance with the international rules of law.

Počítačová simulace kolapsu budovy zplastizováním kloubů / Computer simulation of building collapse due to formation of plastic hinges

Valeš, Jan January 2012 (has links)
The aim of the thesis is to create an analytical 2D model of a multi-storey building and its consequent loading until the point of collapse which occures due to formation of plastic hinges. The first part is going to present a linear analysis of the problem; it focuses on location and level of load when the plastic hinges are formed. Then a nonlinaer analysis is going to be performed by RFEM programme using postcritical analysis and dynamic relaxation. Differences between the results of mentioned types and methods of analysis are going to be compared and an impact of variables is going to be evaluated .

Nejvýznamnější etapy ve vývoji měnové politiky ČNB / The most significant phases of the monetary policy of the Czech National Bank

Krahulcová, Iveta January 2017 (has links)
The diploma thesis deals with the analysis of the most significant phases of the monetary policy of the Czech National Bank, including the analysis and evaluation of its effectiveness from its origin to the present. The thesis is divided into three individual parts. Each part corresponds to a specific transmission mechanism applied by the Czech National Bank while implementing the monetary policy. Each chapter includes the assessment of the effectiveness of individual approaches and the analysis of the impact of the monetary policy as well as the decision of the Czech National Bank on the Czech economy. The very first chapter is focused on the application of the monetary transmission mechanism in conditions of the fixed exchange rate during which an increasing internal as well as external disequilibrium led to the monetary crisis. The second chapter is dedicated to the transition to the inflation targeting, expert discussion concerning its implementation and the evaluation of the achieved results. The last chapter presents the use of the CNB's additional instrument of the monetary policy in the form of the exchange rate including the reasons that led to this step. The closing part of this chapter focuses on the evaluation of the effectiveness of this policy.

Společný konsolidovaný základ daně z příjmů právnických osob ( CCCTB ) a jeho možné dopady pro Českou republiku / Common Consolidated Corporate Taxe Base (CCCTB) and the impacts on the Czech republic

Prošková, Radmila January 2007 (has links)
As a result of a growing number of Member States of the European Union the idea of unification and co-ordination of legal changes,including tax systems of each country, is growing stronger. The common consolidated corporate tax base (CCCTB) should establish unified rules for determining the tax base, and consequently this would eliminate double taxation, cross-border income, or tax evasion and suppression of tax competition among the states of the European Union. This work deals with the redistributive mechanism of the CCCTB, which would alocate the CCCTB to the group of the individual companies. Interim result of the discussion is to create a distribution threefactors formula consisting of variables - work, asset and sales. I applied the current conclusions of the European Commission to the Czech company Skoda Auto,a.s., whose parent company is in Germany.

Výpočtové modelování hluku vyzařovaného tramvajovým kolem při průjezdu zatáčkou / Computational modeling of noise emitted by tram wheel during cornering

Motyka, Jakub January 2017 (has links)
This thesis deals with computational modeling of curve squeal noise phenomena which occurs during cornering tight curves by trams. Lateral creep between rail and wheel and slip-stick phenomena leads to self-excited vibrations of the wheel which, therefore, emits unpleasant high-pitched noise. Two FEM models in frequency domain are carried out. First model is based on prestressed modal analysis. Due to unsymmetric stiffness matrix, unstable eigenvalues can occur. It is assumed that self-excited vibrations occurs on frequencies corresponding to that eigenvalues. Second model uses harmonic response analysis. It examines vibrations of the wheel excited by lateral creep force acting in contact region. This force is obtained externally by simple time-domain model. Results from harmonic response are used consequently for noise radiation computation.
