Vývoj a optimalizace systémů pro SERS na úrovni jedné molekuly / Development and optimization of systems for SERS on single molecule levelMichlová, Magdalena January 2012 (has links)
AABBSSTTRRAACCTT Dimers and small aggregates as well as compact aggregates of Ag nanoparticles (NPs) were assembled and chemically anchored to supporting surfaces. The supporting surfaces were either glass slides or SiO2 - coated Cu or Au grids for TEM, both chemically functionalized by 3-aminopropyltrimethoxysilane (APTMS). Compact aggregates of Ag NPs incorporating protoporphyrin IX (PPIX) molecules were prepared by adsorption of chlorides in the presence of PPIX. Dimers and small aggregates of Ag NPs were assembled by selected molecular linkers: 4,4'-diaminoazobenzene (DAAB), 4,4'-diaminoterphenyl (DATP) and 5,10,15,20-tetrakis(4-aminophenyl)porphine (TAPP). The most efficient strategy of dimers and small aggregates preparation has been their assembling by a three - step procedure involving (i) attachment of isolated Ag NPs to the NH2 groups of APTMS functionalized TEM grid, (ii) attachment of molecular linker (with two functional NH2 groups in para position) to Ag NPs by a one terminal NH2 group, and (iii) attachment of Ag NPs to the second, free terminal NH2 group of the linker. In this procedure, the control over the perpendicular orientation of the bifunctional linker and its attachment by one terminal group to Ag NP surface has been accomplished by functionalization of Ag NPs by adsorbed citrate...

Portál - integrace na úrovni přístupu / Portal - Access IntegrationZelinka, Tomáš January 2007 (has links)
This diploma thesis concerns enterprise portals and its objective is to map their functional support, which they can bring to the company. Especially to the access integrationarea. To achieve this goal the following proces was selected: The first step was to create theoretical background which describes the area of enterprise portals and how it can be seen. In the following part were set main functional areas whose coverage may be assured by the enterprise portal. These areas are : presentation, personalization and customization, security, administration, content management system, search, collaboration, accessibility and portlets. Another part is focused on the selection of specific portal solutions which are evaluated and compared at the conclusion. These are chosen products : IBM WebSphere Portal, Microsoft Sharepoint Server 2007, Oracle Portal 10g, BEA WebLogic Portal. Personal benefit is particularly comprehensive look into the issue of enterprise portals. Theoretical background makes possible to quickly obtain information which are presented in a logically organizace form. It will ensure continuity in the knowledge absorption. Practical part offers look into the enterprise portal market situation and shows what can offer specific product and at what level.

Model systému UMTS / Model of UMTS SystemSrdínko, Milan January 2008 (has links)
Spread Spectrum Communication techniques have been widely used in mobile and wireless communications. They have very beneficial features like antijam and security (noise-like character, pseudorandom codes usage). At first, the features of Spread Spectrum systems are described with emphasis on the Direct Sequence Spread Spectrum (DS-SS) scheme. Main specifications of UMTS system are also introduced. The goal of this thesis was to create the model of a physical layer UMTS suitable for investigation of disturbing signals influences in Matlab Simulink. This model was used to measure how the Bit error rate (BER) is affected by the Processing gain and the Signal-to-noise ratio. Finally, two important charts which describe the relation of Bit error rate versus the Processing gain and the Signal-to-noise ratio have been plotted.

Využití syntézy na systémové úrovni pro aplikace s platformou ZYNQ / Using High-Level Synthesis for ZYNQ Platform ApplicationsHusák, Jiří January 2015 (has links)
This work describes using High-Level Synthesis in image processing application. The application is for Xilinx ZYNQ platform. The source code of components for FPGA is written in C++ programming language. For High-Level Synthesis is used Xilinx Vivado HLS tool. In the application are designed and implemented Sobel filter, Median filter, Bilateral filter and architecture for AdaBoost classificator. The extension of this work is implemented the component for network traffic. The component finds the begin of the packet.

Rezervování škod pro individuální škodní data / Loss reserving for individual claim-by-claim dataBednárik, Vojtěch January 2018 (has links)
This thesis covers stochastic claims reserving in non-life insurance based on individual claims developments. Summarized theoretical methods are applied on data from Czech Insurers' Bureau for educational purposes. The problem of estimation is divided into four parts: oc- curence process generating claims, delay of notification, times between events and payments. Each part is estimated separately based on maximum likelihood theory and final estimates allow us to obtain an estimate of future liabilities distribution. The results are very promis- ing and we believe this method is worth of a further research. Contribution of this work is more rigorous theoretical part and application on data from the Czech market with some new ideas in practical part and simulation. 1

Využití controllingu v centru sdílených služeb / Application of Management Control System in a Shared Services CentreŠteinhüblová, Katarína January 2018 (has links)
The master thesis deals with the status of management control system in shared services center of analyzed company in cooperation with controlling department of the local branch office in Slovakia. Theoretical part of the theses focuses on the theoretical basis for the analytical part, concerning the theory of controlling, centers of shared services in general and the transfer of controlling activities to them. The analytical part includes the analysis of current state of the controlling activities transfer and the cooperation between local controllers and controllers in shared services center. In the final part of the thesis are proposed recommendations and suggestions for possible improvements of management control system as a subsystem of management in the company.

Exploring Contextual Information in Neural Machine Translation / Exploring Contextual Information in Neural Machine TranslationJon, Josef January 2019 (has links)
Tato práce se zabývá zapojením mezivětného kontextu v neuronovém strojovém překladu (NMT). Dnešní běžné NMT systémy překládají jednu zdrojovou větu na jednu cílovou větu, bez jakéhokoliv ohledu na okolní text. Tento přístup je nedostačující a neodpovídá způsobu práce lidských překladatelů. Pro mnoho jazykových párů je dnes za splnění určitých (přísných) podmínek výstup NMT nerozeznatelný od lidského překladu. Jedna z těchto podmínek je, že hodnotitelé skórují přeložené věty nezávisle, bez znalosti kontextu. Při hodnocení celých dokumentů je výstup NMT stále hodnocen hůře, než lidský překlad, i v případech, kdy byl na úrovni jednotlivých vět preferován. Tato zjištění jsou motivací pro výzkum zapojení kontextu na úrovni dokumentu v NMT, je totiž možné, že na úrovni vět již není mnoho prostoru ke zlepšení, alespoň pro jazykové páry a domény bohaté na trénovací data. Tato práce shrnuje současné přístupy zapojení kontextu do překladu, několik z nich je implementováno a vyhodnoceno v rámci obecné překladové kvality i na překladu specifických fenoménů souvisejících s kontextem. Pro zhodnocení kvality jednotlivých systému byla ručně vytvořena testovací sada pro překlad z anglického do českého jazyka.
