MPLS based virtual private networks
Daněk, Michal ; Červenák, Rastislav (referee) ; Novotný, Vít (advisor)
Master thesis deals with architecture of network based on multiprotocol label switching technology (MPLS). Work also describes use of this technology for point to point or multipoint connections based on network or data link layer. The practical part is focused on design of laboratory task which is aimed to configuration of virtual private LAN service (VPLS). This technology emulates multipoint connection based on the data link layer.

Simulation of toroid coils in Ansoft Maxwell 3D
Daněk, Michal ; Pfeifer, Václav (referee) ; Hanák, Pavel (advisor)
The master thesis is focused on the simulation of the toroid coils in Ansoft Maxwell 3D software, which uses finite element method for electromagnetic field simulation. Firstly the process creation of the geometric model toroid coil with seventy-five threaded is presented. It is necessary to debug this model and prepare it for the mesh generation. Physical properties are assign to this model and it gives rise to the physical model. We will set boundaries, excitation current, core material, winding material and the parameters for the mesh generations. New material Kashke K4000 will be created in the materials library and subsequently we will define its BH curve on the basis of datasheet. Analysis is made in two modes. Direct currents (7,5A; 10A; 15A; 20A; 25A) and (non)linear materials are used in magnetostatic solution. Toroid coil is excited by current pulse in transient solution. In Ansoft Maxwell Circuit editor a source which generates current pulse will be created. This excitation will be assigned to the toroid coil as an extern source through a terminal. Core material is linear in the case of transient analysis, because Ansoft Maxwell 3D doesn´t allow to use nonlinear material in this solution. Settings are different in transient and in magnetostatic analysis. End time and time step are entered to solve this task in transient analysis. Time points are entered too. Flux density and electromagnetic field strength are calculated in these time points and later it will be possible to view the results. Calculated fields are shown as the pictures in this thesis. The procedure how to use a field calculator in the postprocessing is given as well. The achievements are summarized in the conclusion.

Characterization of Arabidopsis thaliana FLOTILLINs and HYPERSENSITIVE INDUCED RESPONSE proteins - dynamics, interactions and functions
Daněk, Michal ; Martinec, Jan (advisor) ; Baluška, František (referee) ; Ovečka, Miroslav (referee)
This work is a collection of three research articles and one review article focused on flotillins (FLOTs) and hypersensitive induced reaction proteins (HIRs) in Arabidopsis thaliana. FLOTs and HIRs are closely related membrane-associated proteins forming two subfamilies both belonging to SPFH domain superfamily. While FLOTs are present in organisms of all evolutionary lineages HIRs are plant specific proteins. The review article sums up the knowledge gained on FLOTs and HIRs from different organisms in terms of cellular localization, interaction with cellular membranes and with other proteins, and physiological functions. The research articles were targeted at three aspects of AtFLOTs and AtHIRs: involvement in response to exogenous stimuli; determination of protein interactors; and subcellular localization and dynamics. The first aspect was approached by transcription measurement of AtFLOTs and phenotypic screen of single loss-of-function mutants of AtFLOTs upon various treatments covering biotic and abiotic stress and phytohormone application. Although we observed changes in transcription none of the treatments provoked a phenotype manifestation in any of AtFLOT mutants. In the second article we focused on interactome of AtFLOT2 and performed co- immunoprecipitation followed by mass spectrometry...

Ecophysiology of peat bog ericoid subshrubs - freezing resistance and water relations
Daněk, Michal ; Sklenář, Petr (advisor) ; Hájek, Tomáš (referee)
The seasonal changes in freezing resistance and water relations in four dwarf shrub species of Ericaceae family: Vaccinium vitis-idaea, V. myrtillus, V. uliginosum and Oxycoccus palustris in two study areas differing in altitude were studied in this work. To establish the freezing resistance, the plants were sampled eight times, to determine parameters of the water relations, the plants were sampled six times during the growing season of 2009. For the freezing resistance examination, ice nucleation temperature (exotherm) and 50 per cent lethal temperature (LT50) were found. The water relations were described using the parameters derived from the pressure-volume curves: osmotic potential at full turgor, osmotic potential at zero turgor, cytoplasmic water fraction, relative water content at turgor loss and bulk modulus of elasticity. An important seasonal variability in the freezing resistance was found. The highest levels of the freezing resistance were reached in the spring and in the autumn, the lowest levels were found in the summer. There were also changes in the used mechanisms of the freezing resistance - for most of the year, the plants were tolerant, they showed the avoidance mechanism only in the summer. The seasonal changes in the water relation parameter were less unambiguous. The most of...

Intelligence services and control of their activities in the Czech Republic
Daněk, Michal ; Kudrna, Jan (advisor) ; Grinc, Jan (referee)
Intelligence services and control of their activities in the Czech Republic Abstract The main focus of this thesis is the control of intelligence services in the Czech Republic. The first two chapters define the basic terminology and theory of intelligence services. The third chapter deals briefly with the historical context and development of intelligence services in the Czech Republic. In the fourth chapter, the thesis describes the powers and activities of intelligence services. And the most extensive fifth chapter, which follows, is focused on the control of activities of intelligence services of the Czech Republic. The control of intelligence services is, in general, difficult to implement, it often requires compromises due to the specifics of properties of intelligence services and because of the existence of several conflicts of interests of the involved parties. Probably the most significant conflict of interest is between transparency, information rights and protection of fundamental rights and freedom of individuals on the one hand and providing of the highest possible level of professionality and efficiency of intelligence services, on the other hand. It can be stated that in the past there used to be, and there still remains, some space for improvement in the area of control over the activities...
