Image Processing in FPGA

Tato bakalářská práce pojednává o hardwarové realizaci grafického algoritmu pro vykreslování objektů popsaných pomocí 3D point clouds - reprezentace prostorových objektů. Základ pro implementaci funkčních jednotek tvoří FPGA (Field-Programmable Gate Array) párované s DSP (Digital Signal Processor). Využitím více párů a s tím spojenou distribucí zátěže vzniká zajímavá možnost zrychlování výpočtů. Vstupními daty jsou takzvané 3D point clouds, neboli množiny bodů, které jsou pro účel vykreslení převedeny na orientované kružnice promítnuté do 2D - elipsy. Jako grafická reprezentace se jeví pro spoustu účelů mnohem použitelněji, než nejběžněji používané sítě trojúhelníků. Popsána je i samotná implementace odpovídající návrhu systému.This bachelor's thesis presents a hardware realization of graphic algorithm for rendering objects described with 3D point clouds - a spatial objects representation. An FPGA (Field-Programmable Gate Array) chip coupled with a DSP (Digital Signal Processor) creates basement for implementation of function units. Is possible to decrease overall computation time by using more than one of that pair. That mean so simple distribution of load is used. The input graphical data is 3D point clouds - sets of points which are transformed into oriented circles just for purpose of rendering. Result of projection of that elements are ellipses. Such graphical representation seems to be more suitable for many purposes than the most commonly used triangle meshes. The implementation equivalent to concept is described too.

Alternative firm theories: Can they be applied in a business environment?

Diplomová práce se zabývá alternativními teoriemi, které vznikly jako reakce na diskrepanci mezi předpoklady neoklasické teorie firmy a skutečným charakterem současných firem. Cílem diplomové práce je posoudit, zdali alternativní teorie nabízejí přesnější popis chování firem a zdali jsou schopny neoklasickou teorii nahradit. V první části jsou analyzovány rozdíly mezi předpoklady neoklasické teorie firmy a skutečným stavem reálných firem v dnešních ekonomikách. V druhé části jsou charakterizovány jednotlivé modely alternativních teorií. Tyto modely jsou následně vyhodnoceny a porovnány s neoklasickou teorií, jsou vyzvednuty jejich výhody a nevýhody. Třetí část shrnuje závěry předchozích kapitol a zodpovídá otázky diplomové práce.Diploma thesis deals with alternative theories that have arisen as a reaction to the discrepancy between assumptions of neo-classical theory of the firm and the actual state of the current companies. The aim of thesis is to assess whether alternative theories are offering a more precise description of the behavior of companies and whether they are able to substitute the neoclassical theory. In the first part, differences between assumptions of neo-classical theory of the firm and the actual state of real companies in today's economies are analyzed. Alternative theories are characterized in the second part. These models are then evaluated and compared to neoclassical theory. Characteristics of each model are followed by summary of the model which goal is to point out advantages and disadvantages of each model. The third part summarizes findings of each chapter and answers questions of the thesis

Algorithms for Signal Processing in FPGA

Tato diplomová práce pojednává o možnostech zpracování signálů pomocí digitálních zařízení. Zejména se jedná o analýzu odezvy Dopplerova radaru a následné získání informací o detekovaném objektu (rychlost, směr pohybu, délka, ...). Jde však o málo probádanou oblast, a proto je nezbytné vypůjčit si některé postupy z různých oborů, více či méně příbuzných informačním technologiím. V případě využití nekonvenčních výpočetně náročných metod, které však lze snadno provádět souběžně, je předpokládána hardwarová realizace na čipech FPGA. Propojením s radarovým modulem vzniká velmi rychlý on-line systém, schopný řešit většinu úkonů přímo a v reálné čase. Na výstup jsou pak s minimálním zpožděním odesílána již zpracovaná a transformovaná data, která je možno vizualizovat a zobrazit.This master's thesis describes ways of signal processing via digital devices. Major field of interest is an analysis of Doppler radar response and then mining of informations about detected object (e.g. speed, movement direction, length, ...). There was realized too little research, that's why borrowing some procedures from different branches not too much related to the IT is necessary. In case of using very complex methods that are easy to parallel, hardware implementation on the FPGA is supposed. With transceiver there is created a very powerful on-line system able to process most of tasks real-time. Then processed and transformed data are sent to the output so visualization and display can be made.

Design and management of image processing pipelines within CPS : Acquired experience towards the end of the FitOptiVis ECSEL Project

Cyber-Physical Systems (CPSs) are dynamic and reactive systems interacting with processes, environment and, sometimes, humans. They are often distributed with sensors and actuators, characterized for being smart, adaptive, predictive and react in real-time. Indeed, image- and video-processing pipelines are a prime source for environmental information for systems allowing them to take better decisions according to what they see. Therefore, in FitOptiVis, we are developing novel methods and tools to integrate complex image- and video-processing pipelines. FitOptiVis aims to deliver a reference architecture for describing and optimizing quality and resource management for imaging and video pipelines in CPSs both at design- and run-time. The architecture is concretized in low-power, high-performance, smart components, and in methods and tools for combined design-time and run-time multi-objective optimization and adaptation within system and environment constraints.Peer reviewe

Derivatives of carbazol and their influence on melting point of DNA duplexies I.

Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Drug Control Student: LukášMaršík Supervisor: Mgr. Jan Švec, Ph.D. Expert adviser: PharmDr. KamilKopecký, Ph.D., doc. PharmDr. Miroslav Miletín, Ph.D. Title of diploma thesis: Derivatives of carbazole and their influence on melting point of DNA duplexes I. This diploma thesis deals with preparation of carbazole derivatives bearing bulky basic groups in positions 3 and 6 and an aliphatic chain terminated with azide group in position 9. In the theoretical part, there are described possible methods, how to create basic functional groups on carbazole and other aromatic structures, further the possibility of establishing an aliphatic chain on the aromatic nitrogen and in the last part creation a basic centres on aromatics with a functional group was explored - mostly bromide derivatives were employed as the starting structure. The experimental part deals with the application of methods described in the theoretical part on the structure of carbazole. As the starting molecule 3,6-dibromo-9H-carbazole was used; methods of exchange bromine by carbon or nitrogen containing groups were tested, followed by the creation of the aliphatic chain on the nitrogen of carbazole terminated with azide group and..
