Parallelization of Ultrasound Simulations Using 2D Decomposition
Nikl, Vojtěch ; Dvořák, Václav (referee) ; Jaroš, Jiří (advisor)
This thesis is a part of the k-Wave project, which is a toolbox for the simulation and reconstruction of acoustic wave felds and one of its main contributions is the planning of focused ultrasound surgeries (HIFU). One simulation can take tens of hours and about 60% of the simulation time is taken by the calculation of the 3D Fast Fourier transforms. Up until now the 3D FFT has been calculated purely by the FFTW library and its 1D decomposition, whose major limitation is the maximum number of employable cores. Therefore we introduce a new approach, called the 2D hybrid decomposition of the 3D FFT (HybridFFT), where we combine both MPI processes and OpenMP threads to reach as best performance as possible. On a low number of cores, on the order of a few hundreds, we are about as fast or slightly faster than FFTW and pure MPI 2D decomposition libraries (PFFT and P3DFFT). One of the best results was achieved on a 512^3FFT using 512 cores, where our hybrid version run 31ms, FFTW run 39ms and PFFT run 44ms. The most significant performance advantage should be seen when employing around 8-16 thousand cores, however we haven't had an access to a machine with such resources. Almost a linear scalability has been proven for up to 2048 employed cores.

Specifics regarding methods of interpretation of the EU law and process of EU directives transposition
Hosnedl, Daniel ; Ondřejek, Pavel (advisor) ; Tryzna, Jan (referee)
Specifics regarding methods of interpretation of the EU law and process of EU directives transposition Abstract This thesis is dedicated to the problematics regarding specifics of the European Union law interpretation methods. While majority of publications dealing with law interpretation adopts the perspective of judges and courts, and thus deals with the interpretations they render, this study adopts the viewpoint of a Czech legislator, who is facing a challenging task of transposing directives into the Czech legal order. In order for the transposition to be conducted properly, a thorough interpretation of the respective directive must precede. There is six standard and non- standard methods of interpretation at the legislator's disposal, including linguistic, logical, systematic, historical, theological and comparative one. Do these methods, however, prove to be fully applicable in case of the interpretation of the EU directives? Possibly, what would be the EU law norms interpretation specifics? This study represents an analysis of the given topic from the perspective of a legal theory and is structured into three main sections. The first section provides a brief definition of the legal interpretation as such and presents an overview of both historical and contemporary approaches towards the...

Transposition of environmental directives into the Czech legal order and its problematic aspects
Vinařská, Lucie ; Váška, Jan (advisor) ; Černovská, Eliška (referee)
This bachelor thesis deals with the transposition of environmental directives into the legal order of the Czech Republic. It describes in detail the process of transferring the law into national legislation and, at the same time, it examines the problems that arise here. The aim of this thesis is to clarify the most fundamental issues that occur when transposing environmental directives based on literature and practice. The causes of inappropriate transposition are selected from relevant literature and subsequently examined in case studies. These case studies concern six directives from two areas of environmental law. Chemical pollution area with worse overall transposition results and waste management with better results. Directives from the European Commission's database, which have gone furthest in infringement procedures, have been selected for the investigation. Using both national and European documents, both legislative and non-legislative, the process of transposing individual directives has been described. Based on the research, it has been found that the waste directives have been unduly transposed because of incorrect or incomplete transposition measures, non-communication, on the other hand, dominated the chemicals directives. The research also confirmed the main reasons for problems...

The accounting duties for the middle accounting units
Vízková, Daniela ; Skálová, Jana (advisor)
The bachelor thesis deals with the accounting duties for the middle accounting units, which have come after the amendment to the Accounting Act. The theoretical part is focused on accounting regulation, its methods and instruments in the form of directives. Subsequently, individual directives, their changes and their cancellations are described together with the transposition process into national law. The theoretical part also includes the amendment to the Accounting Act and the list of substantial changes effective from 1st January 2016, particularly the categorization of accounting units and their duties. In the practical section, the internal directives of particular accounitng unit are analysed and changes are introduced together with new obligations that the accounting unit must obey after the amendment to the Accounting Act.

Stay of the third-country nationals in the Schengen Area in the common visa policy framework
Murad, Daniela ; Tomášek, Michal (advisor) ; Pítrová, Lenka (referee)
The thesis deals with the development of the Schengen cooperation and characteristic of the Schengen acquis transforming in the course of time, with the stress on the field of visa and residence/migration policy. Main emphasis is on the valid legislation concerning the status and stay of the third country nationals. The thesis looks into problematic parts of the legislation, both theoretical and practical, and provides opinion of the author on those matters. The thesis is divided into four main spheres. The first one concerns development of a visa and migration policy in the framework of development of the Schengen cooperation and its gradual integration into the main EU policies, its definitions and different participation of the Member States. Following key part of the thesis deals with the current valid provisions of the stay of the third country nationals (citizens of the countries outside of the EU). This part defines subjects of law coming from the third countries, as differentiated by the Union and Czech law and defines various types of authorization to stay which entitle them to short or long-stay at the Schengen or Czech territory. The third segment deals with the family members of the EU nationals who are covered by specific legal framework. Last part of the thesis encompasses future...

Endogenous retroviral elements and their functions in the human genome
Famfulíková, Mirka ; Pačes, Jan (advisor) ; Lichá, Irena (referee)
In addition to the coding sequences, the human genome contains a so noncoding DNA, among which we count transposable elements capable of transposition in the genome. The remnants of the past retrovirus infections - endogenous retroviruses (human endogenous retroviruses - HERVs) belong to the transposable elements, which contain the LTR sequences. Human endogenous retroviruses make up to 8% of the size of the human genome. The retroviruses are not only passive relicts, but they have gained some key functions - too. They increase the plasticity of the human genome and some HERV LTRs can serve as binding sites for transcription factors like. Env protein from the families HERV-W and HERV- FRD were coopted by the human genome and are nowadays expressed as proteins Syncitin-1 and Syncitin-2, which are necessary by the forming of human placenta. Unfortunately, the HERV elements can have a negative health impacts. In the last decades they are subject of a debate in connection with various diseases, such as multiple sclerosis, schizophrenia, HIV proliferation and some types of tumorigenesis. The role of HERVs in the human genome is not completely known yet and it is important to continue with their research. Powered by TCPDF (www.tcpdf.org)

Symbol, sign. Citations and use of work of art as a creative principle
Fricová, Soňa ; Velíšek, Martin (advisor) ; Bláha, Jaroslav (referee)
The thesis is dedicated to a postmodern use of symbol and sign. It is based on set definitions of major terms in the fine art and maps the space between a word and a picture as well as impersonal understanding of computer-generated codes. Didactic part enables to work with symbol and sign in art education. An analytical and syntactical thinking, the knowledge of the art history and the ability of intellectual fabrication are the basic ideas of the thesis. Art works, that use multilevel symbol expressions and are formally based on a postmodern thinking, are introduced in a practical part of the thesis.
