Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.

Reliable computation and local mesh adaptivity in limit analysis
Sysala, Stanislav ; Haslinger, Jaroslav ; Repin, S.
The contribution is devoted to computations of the limit load for a perfectly plastic model with the von Mises yield criterion. The limit factor of a prescribed load is defined by a specific variational problem, the so-called limit analysis problem. This problem is solved in terms of deformation fields by a penalization, the finite element and the semismooth Newton methods. From the numerical solution, we derive a guaranteed upper bound of the limit factor. To achieve more accurate results, a local mesh adaptivity is used.

Issues of criminal liability of legal entities
Hudáková, Jana ; Gřivna, Tomáš (advisor) ; Herczeg, Jiří (referee)
Hudáková, J. Criminal liability of legal persons Criminal liability of legal persons is a significant change to the continental European law. It is a sensible breakthrough into the core principle of an individual criminal responsibility of individuals. In connection with the adoption of Act No. 418/2011 Coll., on the criminal liability of legal persons and proceedings against them, the thesis deals with main aspects of the criminal liability of legal persons in the Czech Republic. After defining of legal grounds of the criminal responsibility author subsequently discusses sanctioning of legal persons. At the same time, the author discusses legal regulation of moral person criminal liability in France. She outlines the principles of criminal liability of legal persons, as well as the conditions for imposing sanctions. The author tries to demonstrate, by means of the attached statistical surveys, the numerous application of this institute in the French legal practice. Finally, the author tries to compare Czech and French legislation in selected aspects.

Possibilities of imposition fines on individuals in public procurement review
Scholle, Jan ; Pavel, Jan (advisor) ; Zídková, Hana (referee)
The thesis focuses on the possibility of implementing imposition fines on individuals who act against public procurement law in the Czech Republic. It is based on current method of sanctioning only legal entities in case the Czech public procurement law is infringed. It also describes the possibility to shift thus imposed fines to individuals, which is considered insufficient. For this reason the thesis argues in favour of change. The thesis seeks for inspiration in both international and European legal documents on public contracts, but the most important contribution is a comparative analysis of the respective laws on public procurement in almost all member states of the European Union. Based on the obtained data, the thesis comes up with four different systems of penalizing individuals in the member states and uses them for proposing three possible models of punishing the individuals in the Czech Republic.
