Robots are present each time more on several areas of our society, however they are still considered expensive equipments that are restricted to few people. This work con- sists on the development of control techniques and architectures that make possible the construction and programming of low cost robots with low programming and building complexity. One key aspect of the proposed architecture is the use of audio interfaces to control actuators and read sensors, thus allowing the usage of any device that can produce sounds as a control unit of a robot. The work also includes the development of web ba- sed programming environments that allow the usage of computers or mobile phones as control units of the robot, which can be remotely programmed and controlled. The work also includes possible applications of such low cost robotic platform, including mainly its educational usage, which was experimentally validated by teachers and students of seve- ral graduation courses. We also present an analysis of data obtained from interviews done with the students before and after the use of our platform, which confirms its acceptance as a teaching support tool

Database and database technology are having a major impact on the growing use of computers. The rising popularity of database systems for the management of data has resulted in an increasing number of systems. As the number grows, the difficulty in choosing the system which will best meet the requirements of a particular application also increases. Knowing how to choose the correct one for a given application is important.The purpose of this thesis is to compare two very commonly used Database Management Systems (ORACLE and RDB) at Ball State University by describing and listing the advantages of each of them as well as their weaknesses, giving a comprehensive study of their performances, user friendliness, limits, and to aid users and managers in obtaining a deeper knowledge of these two systems.Department of Computer Science

Databases and database technology are having a major impact on the growing use of computers. It is fair to say that databases are playing a critical role in almost all areas where computers are used, including business, engineering, medicine, law, education, and library science, to name a few.At Ball State University, databases are very widely used among faculty, staff, and students. The common commercial database management system (DBMS) used in the university is ORACLE. Due to the extensive use of the system and the availability and easy access to alternative systems such as RDB/VMS, a comparative research is in order.This thesis is a comprehensive comparison between the two systems. It covers the differences in design, SQL codings, and the use of host programming language such as FORTRAN. It concentrates on the differences in memory usage, execution time, as well as the CPU time needed to precompile, link, and run.Department of Computer Science

Ziel des BMWi-Fördervorhabens 1501393 ist es, durch den Einsatz von Untersuchungsmethoden auf der nm-Skala einen Beitrag zur Aufklärung von Flusseffekten und von Late-Blooming-Effekten in bestrahlten RDB-Stählen zu leisten. Zur Untersuchung dieser Effekte wurde auf RDB-Stähle deutscher Reaktoren aus zwei bei der AREVA GmbH abgeschlossenen Vorhaben zurückgegriffen. Die Auswahl der Grundwerkstoffe und Schweißgüter erfolgte so, dass sich optimale Voraussetzungen für das Erreichen des Gesamtziels des Vorhabens ergeben. Die ausgewählten Untersuchungsmethoden umfassen mit der Neutronenkleinwinkelstreuung, der Atomsondentomographie und der Positronen-annihilationsspektroskopie solche Techniken, die die nm-skaligen bestrahlungsinduzierten Defekt-Fremdatom-Cluster bestmöglich und in komplementärer Weise zu detektieren und zu charakterisieren gestatten. Es wurde ein Flusseffekt auf die Größe der bestrahlungsinduzierten Fremdatomcluster, jedoch nicht auf den Volumenanteil und die mechanischen Eigenschaften gefunden. In einem Cu-armen RDB-Schweißgut wurde ein Late-Blooming-Effekt nachgewiesen, der sich in einem steilen Anstieg des Clustervolumenanteils und der Übergangstemperaturverschiebung nach einer Phase schwacher oder fehlender Zunahme niederschlägt.
The BMWi project 1501393 aimed at contributing to the clarification of flux effects and late blooming effects in irradiated RPV steels by means of experimental techniques of sensitivity at the nm scale. The investigation of these effects was focussed on RPV steels, both base metal and weld of German reactors selected according to the objectives of the present project from two previous projects performed at AREVA GmbH. The complementary techniques of small-angle neutron scattering, atom probe tomography and positron annihilation spectroscopy were applied to detect and characterize the irradiation-induced nm-scale defect-solute clusters. A flux effect on the size of the irradiation-induced clusters but no flux effect on both cluster volume fraction and mechanical properties was found. For a low-Cu RPV weld, a late blooming effect was observed, which results in a steep slope of both cluster volume fraction and transition temperature shift after an initial stage of small or no change.

With the rise of China for the last 30 years, its currency RMB is gaining more presence in the international trading. The Chinese government has been sending positive signals for internationalizing its currency in the recent decade but it still remains a question how it would execute the process. This dissertation focuses on discussing how a government should internationalize its currency, if it is in its interest and what it implies for Chinese government. We first look into the current situation for RMB internationalization. Then we look into Frankel (2014)’s currency theory and three important factors for the currency internationalization: the size of economy, the depth and openness of a country’s financial market, and the confidence in the value of the currency. Then we collect data to exam this theory. We then analyze the positive effect and negative effect of currency internationalization and how China developed coordinate policies in different periods In this dissertation, Frankel (2014) `s theory was proved in a different approach. We selected different variables and period to redid the test. We concluded that the internationalization of its currency is important but not prioritized for China.

Esta dissertação centra-se em discutir como um governo deve internacionalizar sua moeda, se é no seu interesse e o que isso implica para o governo chinês. Primeiro olhamos para a situação atual da internacionalização de RMB. Em seguida, analisamos a teoria da moeda de Frankel (2014) e três fatores importantes para a internacionalização da moeda: o tamanho da economia, a profundidade e a abertura do mercado financeiro e a confiança no valor da moeda. Em seguida, coletamos dados para examinar esta teoria. Em seguida, analisamos o efeito positivo e o efeito negativo da internacionalização da moeda e como a China desenvolveu políticas coordenadas em diferentes períodos. Nesta dissertação, a teoria de Frankel (2014) foi provada em uma abordagem diferente. Selecionamos diferentes variáveis e período para retificar o teste. Concluímos que a internacionalização de sua moeda é importante, mas não priorizada para a China.

The RRB-tree is a confluently persistent data structure based on the persistent vector, with efficient concatenation and slicing, and effectively constant time indexing, updates and iteration. Although efficient appends have been discussed, they have not been properly studied.This thesis formally describes the persistent vector and the RRB-tree, and presents three optimisations for the RRB-tree which have been successfully used in the persistent vector. The differences between the implementations are discussed, and the performance is measured. To measure the performance, the C library librrb is implemented with the proposed optimisations.Results shows that the optimisations improves the append performance of the RRB-tree considerably, and suggests that its performance is comparable to mutable array lists in certain situations.

Full textAbstract:
CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICOA fotoelasticidade é uma ferramenta poderosa para análise de tensões em problemas bi e tridimensionais. Nos últimos anos a técnica vem ganhando renovado interesse da comunidade científica devido à adaptação de modernas técnicas de aquisição e processamento digital de imagens. Uma das linhas mais promissoras é a Fotoelasticidade RGB, que entende a cor como uma combinação única dos níveis de intensidade das componentes Red, Green e Blue. Tratase de uma metodologia poderosa, porém de fácil compreensão e aplicação em ambientes industriais. Uma aplicação tradicional da fotoelasticidade é na inspeção de tensões residuais em componentes de vidro, utilizando-se a Norma ASTM F218. Esta Norma estabelece dois procedimentos para a determinação da ordem de franja isocromática: um quantitativo e outro qualitativo. O vidro tem birrefringência muito baixa, o que faz com que a resposta ótica seja basicamente em tons de cinza. No seu procedimento qualitativo a Norma ASTM F218 recomenda a utilização de um filtro retardador de onda inteira. Com esse simples procedimento, a resposta ótica se modifica. No lugar de tons de cinza tem-se cores em torno da passagem do vermelho para o azul, o que simplifica muito a análise de birrefringência por um operador. A aplicação da Fotoelasticidade RGB para componentes de vidro, transforma este método qualitativo em quantitativo: a cor deixa de ser um parâmetro abstrato, e passa a ser um número. Este trabalho analisa os procedimentos necessários para aplicar a Fotoelasticidade RGB à indústria do vidro. A Norma ASTM F218 recomenda que o filtro de onda inteira, seja inserido com sua direção principal alinhada à direção principal de cada ponto analisado. Foi pesquisada a diferença entre os resultados obtidos, quando a norma é seguida, e quando é utilizado um procedimento simplificado, ou seja, é utilizada apenas uma posição do filtro para analisar todos os pontos. Além disso, o método foi aplicado a dois casos: um esteme e um bulbo de lâmpada. Nos dois casos, foram analisados um componente considerado bom e outro considerado ruim, por seu fabricante, procurando mostrar seus estados de tensões residuais através da Fotoelasticidade RGB.
Photoelasticity is a powerful tool for analyzing stress in bidimensional and three-dimensional problems. In the last years the technique renewed the scientific community s interest due to adaptation of modern acquisition and image digital processing techniques. One of the most promising field is called RGB Photoelasticity. It quantifies the color as an unique combination of the intensity levels of Red, Green and Blue components. It is a powerful methodology,even so of easy understanding and application in industrial enviroment.A traditional application of the photoelasticity is in the inspection of residual stresses in glass components, using the specification ASTM F218. That specification establishes two procedures for the determination of the isocromatics fringe order: one of them quantitative and anotehr one qualitative. The glass has very low birefringence, so that its optic response is basically in gray tones. In the qualitative procedure the specification F218 recommends the use of a full - wave plate. With this simple procedure the optical answer is changed. It is possible to obtain colors near the passage of the red to blue, what simplifies the analysis too much. The application of RGB photoelasticity to glass transforms the qualitative method in quantitative: the color is not more an abstract parameter, but a number. This dissertation analyzes the necessary procedures to apply RGB photoelasticity to the glass industry. The specification F218 recommends that the full wave plate must be inserted with its principal direction aligned to the principal direction of each analyzed point. A implification to that procedure was proposed: to use only one position of the filter to analyze all the points. The difference among the two procedure was researched; the results obtained following the specification and using the simplified procedure were compared. The method has been applied to two cases: a stem and a lamp bulb. In the both cases, a component in the acceptable condition and another in the non-acceptable condition were analyzed, in order to show their states of residual stresses using the RGB photoelasticity.

Full textAbstract:
RGB-D data has turned out to be a very useful representation for solving fundamental computer vision problems. It takes the advantages of the color images that provide appearance information of an object and also the depth image that is immune to the variations in color, illumination, rotation angle and scale. With the invention of the low-cost Microsoft Kinect sensor, which was initially used for gaming and later became a popular device for computer vision, high quality RGB-D data can be acquired easily. RGB-D image/video can facilitate a wide range of application areas, such as computer vision, robotics, construction and medical imaging. Furthermore, how to fuse RGB information and depth information is still a problem in computer vision. It is not enough to simply concatenate RGB data and depth data together. A new fusion method could better fuse RGB images and depth images. It still needs more powerful algorithms on this. In this thesis, to explore more advantages of RGB-D data, we use some popular RGB-D datasets for deep feature learning algorithms evaluation, hyper-parameter optimization, local multi-modal feature learning, RGB-D data fusion and recognizing RGB information from RGB-D images: i)With the success of Deep Neural Network in computer vision, deep features from fused RGB-D data can be proved to gain better results than RGB data only. However, different deep learning algorithms show different performance on different RGB-D datasets. Through large-scale experiments to comprehensively evaluate the performance of deep feature learning models for RGB-D image/ video classification, we obtain the conclusion that RGB-D fusion methods using CNNs always outperform other selected methods (DBNs, SDAE and LSTM). On the other side, since LSTM can learn from experience to classify, process and predict time series, it achieved better performances than DBN and SDAE in video classification tasks. ii) Hyper-parameter optimization can help researchers quickly choose an initial set of hyper-parameters for a new coming classification task, thus reducing the number of trials in terms of hyper-parameter space. We present a simple and efficient framework for improving the efficiency and accuracy of hyper-parameter optimization by considering the classification complexity of a particular dataset. We verify this framework on three real-world RGB-D datasets. After the analysis of experiments, we confirm that our framework can provide deeper insights into the relationship between dataset classification tasks and hyperparameters optimization, thus quickly choosing an accurate initial set of hyper-parameters for a new coming classification task. iii) We propose a new Convolutional Neural Networks (CNNs)-based local multi-modal feature learning framework for RGB-D scene classification. This method can effectively capture much of the local structure from the RGB-D scene images and automatically learn a fusion strategy for the object-level recognition step instead of simply training a classifier on top of features extracted from both modalities. Experiments are conducted on two popular datasets to thoroughly test the performance of our method, which show that our method with local multi-modal CNNs greatly outperforms state-of-the-art approaches. Our method has the potential to improve RGB-D scene understanding. Some extended evaluation shows that CNNs trained using a scene-centric dataset is able to achieve an improvement on scene benchmarks compared to a network trained using an object-centric dataset. iv) We propose a novel method for RGB-D data fusion. We project raw RGB-D data into a complex space and then jointly extract features from the fused RGB-D images. Besides three observations about the fusion methods, the experimental results also show that our method achieves competing performance against the classical SIFT. v) We propose a novel method called adaptive Visual-Depth Embedding (aVDE) which learns the compact shared latent space between two representations of labeled RGB and depth modalities in the source domain first. Then the shared latent space can help the transfer of the depth information to the unlabeled target dataset. At last, aVDE matches features and reweights instances jointly across the shared latent space and the projected target domain for an adaptive classifier. This method can utilize the additional depth information in the source domain and simultaneously reduce the domain mismatch between the source and target domains. On two real-world image datasets, the experimental results illustrate that the proposed method significantly outperforms the state-of-the-art methods.

Full textAbstract:
Les RAB GTPases sont des régulateurs majeurs du trafic vésiculaire et sont localisées sur des compartiments spécifiques. L'identification des processus moléculaires régulant la localisation des RAB est donc cruciale afin de comprendre les mécanismes de transport intracellulaire. Nous sommes parvenus, pour la première fois, à incorporer des protéines RAB purifiées et prénylées dans des membranes artificielles. Nous avons tout d'abord observé que RAB6 est capable de promouvoir une agrégation de vésicules, phénomène qui n'est pas observé avec RAB1 et RAB5. Nous suggérons un modèle dans lequel RAB6 interagit en trans avec lui-même et par conséquent induit un accolement de membranes. La partie principale de cette étude consistait à identifier les propriétés physicochimiques des membranes requises pour le recrutement des protéines RAB. Nous avons observé que RAB1, RAB5 et RAB6 se lient préférentiellement à des membranes désordonnées et courbées, phénomène qui s'explique par l'insertion du groupement prenyl hydrophobe au niveau de défauts d'agencement de lipides. En revanche, le recrutement de RAB35 requiert la présence de lipides chargés négativement et peut être modulé, dans une moindre mesure, par les défauts d'agencement lipidique. Bien que RAB4 et RAB11 soient recrutées sur des fractions de Golgi purifiées, les charges membranaires et les défauts d'agencement lipidique ne sont pas suffisants pour permettre leur recrutement sur des vésicules synthétiques. Cela suggère que le recrutement de RAB4 et RAB11 nécessite des propriétés membranaires plus complexes. Nos travaux démontrent que les propriétés membranaires sont cruciales pour la localisation spécifique des protéines RABRAB GTPases are major regulators of vesicular trafficking and localize to specific compartments. Deciphering the molecular mechanisms governing RAB localization is thus critical to understand intracellular transport processes. We have managed, for the first time, to incorporate purified and prenylated RABs into artificial membranes. By doing so, we observed that RAB6, but not RAB1 or RAB5, is able to promote by itself vesicle tethering. We believe that RAB6 is able to interact in trans with itself and to consequently drive homotypic membrane tethering. In the main part of this study, we investigated the physicochemical membrane requirements necessary for RAB recruitment. RAB1, RAB5 and RAB6 were all found to only localize to disordered membrane domains and to preferentially bind to curved membranes. We demonstrated that this specific recruitment of RAB1, RAB5 and RAB6 is primarily dependent on the hydrophobic insertion of their prenyl group into lipid packing defects. In contrast, RAB35 recruitment was primarily dependent on the presence of negatively charged lipids and was found to be modulated, to a lesser extent, by lipid packing defects. Although RAB4 and RAB11 were effectively recruited to purified Golgi fractions, in an effector-independent manner, membrane charges and lipid packing defects were not sufficient to promote their recruitment to synthetic vesicles; suggesting that RAB4 and RAB11 require more demanding membrane physicochemical properties. Our work demonstrates that the properties of membranes are critical for the regulation of RAB specific membrane targeting

Full textAbstract:
The aim of a presented diploma thesis was to evaluate the level of contamination in fish by nontuberculous mycobacteria (NTM). Methods of molecular biology were used to monitor the incidence and distribution of NTM in tissues of freshwater fish (gills, pharyngeal teeth, muscles, intestine etc.). NTM frequently occur in aquacultures for commercial use. With this in mind the occurrence of NTM was monitored in fish meat (Ctenopharyngodon idella, Cyprinus carpio, Tinca tinca, Sander lucioperca, Oreochromis niloticus etc.) from the market, because processing and consumption of insufficiently heat treated meat contaminated with NTM may pose health risk to humans. The theoretical part deals with the description of mycobacteria, their clinical significance and responsibilities in food safety. There are summarised methods for detection and identification of individual mycobacterial species. The experimental part is devoted to the description of used methods followed by evaluation of experimentally obtained data. The plasmid DNA was prepared as positive controls for PCR reaction. Furthermore, the analytical sensitivity of PCR reaction and efficiency of isolation of mycobacterial DNA isolation from fish meat were determined. Lastly, the level of NTM contamination in fish was evaluated.

The localization of wheeled robot is made using odometry information and landmark detection. These informations are fused using a Extended Kalman Filter. The relative position of humanoid is acquired fusing (using another Kalman Filter) the wheeled robot pose with the characteristics of the landmark on the back of humanoid. Knowing the wheeled robot position and the humanoid relative position in relation to it, we acquired the absolute position of humanoid.

Previous issue date: 2008-05-30This work presents a cooperative navigation systemof a humanoid robot and a wheeled robot using visual information, aiming to navigate the non-instrumented humanoid robot using information obtained from the instrumented wheeled robot. Despite the humanoid not having sensors to its navigation, it can be remotely controlled by infra-red signals. Thus, the wheeled robot can control the humanoid positioning itself behind him and, through visual information, find it and navigate it. The location of the wheeled robot is obtained merging information from odometers and from landmarks detection, using the Extended Kalman Filter. The marks are visually detected, and their features are extracted by image processing. Parameters obtained by image processing are directly used in the Extended Kalman Filter. Thus, while the wheeled robot locates and navigates the humanoid, it also simultaneously calculates its own location and maps the environment (SLAM). The navigation is done through heuristic algorithms based on errors between the actual and desired pose for each robot. The main contribution of this work was the implementation of a cooperative navigation system for two robots based on visual information, which can be extended to other robotic applications, as the ability to control robots without interfering on its hardware, or attaching communication devices

Full textAbstract:
Eukaryotic cells depend on cargo uptake into the endocytic membrane system, which comprises a functionally interconnected network of endosomal compartments. The establishment and maintenance of such diverse compartments in face of the high rates of exchange between them, poses a major challenge for obtaining a molecular understanding of the endocytic system. Rab-GTPases have emerged as architectural key element thereof: Individual family members localize selectively to endosomal compartments, where they recruit a multitude of cytoplasmic effector proteins and coordinate them into membrane sub-domains. Such "Rab-domains" constitute modules of molecular membrane identity, which pattern the endocytic membrane system into a mosaic of Rab-domains. The main objective of this thesis research was to link such "static" mosaic-view with the highly dynamic nature of the endosomal system. The following questions were addressed: How are neighbouring Rab-domains coordinated? Are Rab-domains stable or can they undergo assembly and disassembly? Are the dynamics of Rab-domains utilized in cargo transport? The first part of this thesis research focused on the organization of Rab-domains in the recycling pathway. Utilizing Total Internal Reflection (TIRF) microscopy, Rab11-, but neither Rab4- nor Rab5-positive vesicles were observed to fuse with the plasma membrane. Rab4-positive membranes, however, could be induced to fuse in presence of Brefeldin A. Thus, these experiments complete the view of the recycling pathway by the following steps: a) Rab11-carriers likely mediate the return of recycling cargo to the surface; b) such carriers are presumably generated in an Arf-dependent fission reaction from Rab4-positive compartments. Rab11-chromatography was subsequently carried out in the hope of identifying Rab11-effectors functioning at the Rab4-Rab11 domain interface. An as yet uncharacterized ubiquitin ligase was identified, which selectively interacts with both Rab4 and Rab11. Contrary to expectations, however, the protein (termed RUL for *R*ab interacting *U*biquitin *L*igase) does not function in recycling,but appears to mediate trafficking between Golgi/TGN and endosomes instead.In order to address the dynamics of Rab-domains, fluorescently tagged Rab-GTPases were imaged during cargo transport reactions in living cells. Herefore high-speed/long-term imaging procedures and novel computational image analysis tools were developed. The application of such methodology to the analysis of Rab5-positive early endosomes showed that a) The amount of Rab5 associated with individual endosomes fluctuates strongly over time; b) such fluctuations can lead to the "catastrophic" loss of the Rab5-machinery from membranes; c) Rab5 catastrophe is part of a functional cycle of early endosomes, involving net centripetal motility, continuous growth and increase in Rab5 density. Next, the relevance of Rab5 catastrophe with respect to cargo transfer into either the recycling- or degradative pathway was examined. Recycling cargo (transferrin) could be observed to exit Rab5-positive early endosomes via the frequent budding of tubular exit carriers. Exit of degradative cargo (LDL) from Rab5-positive endosomes did not involve budding, but the rapid loss of Rab5 from the limiting membrane.Rab5-loss was further coordinated with the concomitant acquisition of Rab7, suggesting "Rab conversion" as mechanism of transport between early- and late endosomes.Altogether, this thesis research has shown that first, Rab-machineries can be acquired and lost from membranes. Second, such dynamics provide a molecular mechanism for cargo exchange between endosomal compartments. Jointly, these findings lead to the concept of Rab-domain dynamics modulation in /trans/ between neighbouring domains as mechanistic principle behind the dynamic organization of membrane trafficking pathways.

Re-calibrating a printer in response to systematic changes is measurement and labor intensive. In this study, a fast correction method with cycle-to-cycle control was proposed. The process includes two steps: the creation of look-up table using a characterization data set, and image color compensation in conjunction with Windows printing architecture. Several types of correction models for determining printer characterization were proposed and evaluated, including polynomial models and neural network models. The most successful of these methods was the quadratic spline interpolation model, which removed most errors introduced by the changes of colorant and printing substrate. A significant reduction in error was realized by incorporating this technique into the color management program.

The demand for printing excellent quality images has increased tremendously in parallel to the growth spurts in the digital camera market. Printing good quality images consistently, however, remains a difficult and/or expensive venture despite the numerous advances in color technology and printing. To alleviate these issues, a color compensating software solution was developed to utilize the unique Kikuze calibration chart to improve printer output. The software solution integrates with the windows printing process at the operating system level through a UNIDRV plug-in. The plug-in retrieves the data within the print stream, passes it on to the color compensation engine which corrects the color data by mapping input and output colors obtained via a B-spline interpolation algorithm. The rendered image is re-introduced into the print stream for final printing. The prototype achieved successful results and can be packaged with commercial printers after a few refinements.

Full textAbstract:
One-proton knockout reactions from neutron-rich 17N, 19N, and 21N isotopes have been performed in inverse kinematics at the R3B/LAND setup at GSI in Darmstadt during the experimental campaign S393. They have been measured in a kinematically complete way with a beam energy of 490 AMeV.
This thesis presents the inclusive and exclusive cross sections of Quasi-Free Scattering (QFS) and knockout reactions and compares them with calculations in the Glauber framework. The results are interpreted in a configuration mixing model describing the first excited 2+ state of the fragments as a mixture of a pure proton and a pure neutron excitation. The comparison of the experimental and theoretical cross sections shows that this description is missing short- and long-range correlations. Furthermore, the proton amplitude for the neutron-rich, even-even 16C, 18C, and 20C isotopes is extracted from the ratio of the exclusive cross sections of the first excited 2+ state and the 0+ ground state of the QFS reactions. The results support the two-state mixing picture. The behavior of the proton amplitude can be explained by the reduction of the spin-orbit splitting of the 1p1/2 and 1p3/2 proton orbit as an effect of the tensor force between the protons and the neutrons in the sd shell. Moreover, it helps to understand the increase of the B(E2;2+ → 0+g.s.) quadrupole transition strength towards the neutron-rich 20C isotope.
The analysis leading to these results is presented in detail.
This includes the identification of the incoming and outgoing particles as well as a discussion of several addback algorithms to reconstruct the γ-ray energies. The number of recorded events and problems with the triggering are identified as the main sources for the experimental uncertainties. The γ-ray spectra are compared to simulations. The simulations have been performed in R3BRoot, a software package making use of the GEANT toolkit dedicated to experiments with the R3B setup. In this context, the proton and γ-ray detection efficiencies of the Crystal Ball detector are discussed.
In addition, two position sensitive silicon prototype detectors which will be used as in-beam tracking detectors in the updated R3B setup have been tested at KVI-CART. Their performance, i.e., their energy and position resolution, is investigated in terms of the integration time of the electronic read out. While the energy resolution is best for large integration times, the position resolution improves with decreasing integration time. These findings are discussed in terms of the noise introduced by the resistive surface of the detectors and the resulting pulse shapes.

Tese de mestrado, Engenharia Física, Universidade de Lisboa, Faculdade de Ciências, 2010The trigger logic system of an experimental apparatus is responsible for the data acquisition of that system, i.e., this system decides when data is to be collected. the LAND/ R3B collaboration trigger logic system was updated for the 2010 campaign. In this update the several parts of the trigger system in the different modules were included in one FPGA. This new module so-called VULOM is now responsible for the hole trigger logic and for setting the overall dead time. The FPGA use now implies a 10 ns jitter in the trigger logic signals. This thesis contains the description of the trigger logic system, the old and also the one included in the VULOM. In order to completely understand a experimental setup and the role of the trigger logics, it is necessary to go from the detectors through the conversion of electrical signals to the storage of data. This insight of the electronic setup allowed to start a dead time measurement project. This measurement project main goal is to keep under surveillance the local dead time of the several subsystems. To perform this, it is necessary to keep in mind how the system works and how to synchronize CPU clocks. A plan was outlined and a simulation program was developed to check for its feasibility. Our results suggest that the time required to perform the measurement can be reduced by 30% if the CPU clocks are only corrected with the clocks offset, disregarding the frequency offset. However some simulation improvements are required to further conclusions.

Entre as experiências planeadas para o FAIR, a colaboração R3B (Reactions with Relativistic Radioactive Beams) procura explicar as propriedades nucleares dos núcleos instáveis localizados dentro dos limites da matéria nuclear, as chamadas "drip-lines". A partir da consideração da física a ser estudada na experiência R3B, a detecção de neutrões de alta energia é essencial para a medição das muitas recções que deverão ser observadas. É portanto necessário um espectrómetro ToF de alta resolução para determinar o momento dos neutrões de alta energia resultantes da decomposição do projétil com energias num intervalo de 200 MeV a 1000 MeV. Um dos conceitos para o detector de neutrões NeuLAND é baseado em RPCs (Resistive Plate Chambers). O princípio de detecção do detector usando RPCs baseia-se na detecção de partículas carregadas criadas por chuveiros hadrónicos induzidos por neutrões em materiais. Para a otimização de um possível detector de grande área de 2 x 2 m2 construído com RPCs, várias simulações foram realizadas utilizando o Virtual Monte Carlo framework FAIRROOT. O detector foi desenhado como uma estrutura de módulos de RPCs únicos com 5 gaps de gás agrupados um após o outro num total de módulos suficientes para alcançar uma eficiência de detecção de um neutrão superior a 90%. Foram estudados diferentes materiais como conversores assim como diferentes espessuras das placas de vidro com diferentes configurações geométricas. Aqui serão apresentados os resultados das simulações realizadas assim como a avaliação do desempenho do detector completo e o desempenho de um protótipo que será testado no GSI, na primavera de 2012.
The FAIR (Facility for Antiprotons and Ions Research), a greater improvement compared to current accelerators of the GSI Helmholtz Centre for Heavy Ion Research in Darmstadt, Germany, will become the largest accelerator for nuclear physics in Europe and one of the largest in the world. Among the experiments planned for FAIR, the R3B (Reactions with Relativistic Radioactive Beams) collaboration seeks to explain the nuclear properties of unstable nuclei located within the limits of nuclear matter, the socalled \drip-lines". From the consideration of the physics cases to be studied at R3B, the detection of high energy neutrons is essential for the measurement of the many reactions to be observed. A high-resolution neutron ToF spectrometer is required to determine the momentum of high-energy neutrons resulting from the decay of the projectile with energies in the range of 200 MeV to 1000 MeV. One of the concepts for the neutron detector NeuLAND was based on Resistive Plate Chambers (RPCs). The detection principle of the detector using RPCs relies on the detection of the charged particles created by hadronic showers induced by neutrons on materials. For the optimization of a possible large area detector of 2_2 m2 made with RPCs several simulations were performed using the Virtual Monte Carlo framework FAIRROOT. The detector was design as a structure of single RPCs modules with 5 gas gaps grouped one after another into a total of modules enough to reach an efficiency of one neutron detection higher than 90%. Different materials were studied as converters as well different thickness of glass plates with different geometrical configurations. The results of the performed simulations, the evaluation of the full detector performance, and the expected performance of a prototype to be tested at GSI in the spring of 2012 are presented.

8 ABSTRACT Rab GTPases (Rabs) are the most populous branch of eukaryotic Ras GTPase superfamily. In active GTP-binding conformation, they serve as key instruments in defining transient membrane identity and through various effectors regulate formation, transport, conversion, and fusion of membrane vesicles. This is important for upkeep of compartmentalized structure of eukaryotic cells and for facilitating both endo- and exocytic processes. Rabs are converted into GDP-binding conformation by interactions with Rab GTPase activating proteins (Rab GAPs) that possess ability to significantly speed up weak intrinsic GTP hydrolytic activity of Rabs. Through this process, Rab GAPs can limit scope of the Rabs' activity and lay out spatiotemporal boundaries for varying Rab populations. In this thesis, I tried to characterize a Rab GAP, GAP2, seemingly necessary for standard development of thale cress plants. Besides TBC catalytic domain, GAP2 (product of At2g39280 gene) possesses a C-terminal coiled-coil motif, which was previously found to interact with Rab GTPases. Experiments aiming to complement T-DNA insertion mutant in GAP2, elucidate GAP2 intracellular localization, novel interacting partners, and character of interaction with the Rabs discovered in the pilot study were undertaken. The results suggest that...

In the Czech Republic, but also in the world , is well-known and widespread saying that consumption of fish , fish and fish products for human body healthy. In the Czech Republic, but not consumption of fish and fish products very extended and consuming very lagging . Primarily, we should think about the importance and increasing fish consumption among children , pregnant women and in the elderly . Few people realize what lies beneath onou sentence " is healthy " . Since i I'm interested in a nutrition, good eating habits and everything that could man do to live a little bit healthier life , I chose this work and in the preparation of this topic I've answered the question - " A So what is healthy . " Worth mentioning the fact that in recent times to multiply the opinion that fish Meat is not entirely harmless and beneficial only . I, too, when treatment of this topic came across a chapter concerning possible hazards arising from the consumption of fish and fish meat . In conclusion but I must say that although there is some doubt about the benefit or disadvantage consumption of fish and fish products , always dominated by positive Ratings and always indicates that clear recommendations that consumption fish and fish products should increase , and in our circumstances to double

Accounting as a fundamental basis for reporting the property, resources, results of economic performance, as well as an indirect background material for monitoring parameters of the environment, evaluation of legislation changes and also political ambitions, represents an irreplaceable and, at the same time, complex activity. Accounting is based upon the basic standards and legislation, but it cannot grasp all. What is more, this industry is very specific and locally dependent.

A dissertation submitted to the Faculty of Science, in fulfilment of the requirements for the degree of Masters of Science in the Wits Institute of Data Science (WIDS) School of Computer Science and Applied Mathematics, 2020Object recognition and the subproblem of land cover classification has been a key focus of computer vision research. An increasing number of devices have begun supporting the capture of images with additional bands beyond the standard RGB bands, including depth and other spectra such as near infrared. There is an opportunity to study the use of RGB images with depth and multispectral images to improve the accuracy of the object recognition and land cover classification. We do this by taking existing state-of-the-art object recognition models and modifying them to work with RGB images with depth. For land cover classification we present a novel model, LandNet, which allows varying the number of backbone feature extractors and the image bands in each. We also study the impact of adding the additional depth information, bands and the use of multiple feature extractors on the training and inference times of the models. We find that adding depth data did not show any benefits for object recognition but has little effect on the training and inference times. Utilizing multispectral images allows for improvements for the accuracy of land cover classification. Adding the additional bands in single feature extractor has no effect on the training and inference times, however using multiple feature extractors does increase the training and inference times. The results leads us to conclude that depth data has the potential to improve object recognition accuracy but a larger dataset than SUN RGB-D is required to demonstrate improved performance when using RGB and depth images. We can conclude that using multispectral images for land cover classification has tangible benefits

Face recognition across pose is a challenging problem in computer vision. Two scenarios are considered in this thesis. One is the common setup with one single frontal facial image of each subject in the gallery set and the images of other poses in the probe set. The other considers a RGB-D image of the frontal face for each subject in the gallery, but the probe set is the same as in the previous case that only contains RGB images of other poses. The second scenario simulates the case that RGB-D camera can be available for user registration only and recognition can be performed on regular RGB images without the depth channel. Two approaches are proposed for handling the first scenario, one is holistic and the other is component-based. The former is extended from a face reconstruction approach and improved with different sets of landmarks for alignment and multiple reference models considered in the reconstruction phase. The latter focuses on the reconstruction of facial components obtained by the pose-invariant landmarks, and the recognition with different components considered at different poses. Such a component-based reconstruction for handling cross-pose recognition is rarely seen in the literature. Although the approach for handling the second scenario, i.e., the RGB-D based recognition, is partially similar to the approach for handling the first scenario, the novelty is on the handling of the depth readings corrupted by quantization noise, which are often encountered when the face is not close enough to the RGB-D camera at registration. An approach is proposed to resurface the corrupted depth map and substantially improve the recognition performance. All of the proposed approaches are evaluated on benchmark databases and proven comparable to state-of-the-art approaches.

In response to exchange rate risks to the global financial crisis and European debt crisis, developed countries adopt quantitative easing monetary policy arising from the spillover costs, and the enhancing of the economic strength, in 2009, China began to implement the internationalization of the RMB. The RMB has become the world's sixth-largest currency of payment. Besides, IMF (International Monetary Fund) announced the Yuan to be included in the SDR basket (Special Drawing Right) on October 31, 2015, RMB internationalization process is very fast. For a long time, the Yuan’s value is regarded underestimated. This paper uses the PPP model (Purchasing Power Parity) and Effective Exchange Rate model to estimate the degree of undervaluation of Yuan. The analysis shows that the degree of undervaluation has been greatly improved, and gradually approaching the equilibrium exchange rate. In addition, the RMB exchange rate regime is also a very important issue. After China restarted the RMB exchange rate reform in 2010, the volatility limitation of Yuan against the US dollar is gradually relaxed. China also announced that the exchange rate regime decoupled the US dollar peg to a basket of currencies. This paper uses CFETS RMB exchange rate index’s composition of the 13 kinds of currency rate on a regression analysis to the Yuan. We find out that China’s exchange rate regime is "adjustable peg to a basket". If China wants the Yuan to be an international currency, the exchange rate must be liberalized and the space of manipulation must be minimized.

In 2008, the United States subprime mortgage caused financial crisis, not only making the global economy has been severely affected, but also the US Dollar in international monetary status be questioned, a lot of countries start to reduce their trust of the US Dollar, and they start to think about should they have to proceeded diversification of international reserve currency assets, and put other more stable country’s currency. The financial crisis provided the opportunity for RMB. From the current trend of China''s economic development, international economic environment and other aspects of view, the internationalization of the RMB has been equipped with more favorable conditions for development, China''s economic development for the internationalization of RMB has laid a good foundation. My major study is RMB internationalization. There are three topics to discuss and analyze. (1) What''s the RMB internationalization condition? (2) What are the questions of RMB internationalization? (3) Does the RMB will internationalization success. My research has three comments about RMB internationalization. First, understand conditions of the internationalization currency and analyze the RMB. Second, discuss the use and circulate condition of RMB. Third, government’s policies for the RMB. This research found that The economy、politics、trade and government are conditions of currency internationalization. RMB has been regionalization and expand the ASEAN countries. China government’s policies for RMB are to engage in RMB business、to publish RMB bond and sign the agreement of currency exchange with countries. The questions of RMB internationalization are RMB can not free exchange、has not enough effect in the international trade and invest、Interest and exchange rates have not free etc. All of the questions the RMB can’t free exchange is most important.

In this thesis, we dicuss the design and implement action of a Gateway for O ODB users to access freely to both OODB and any connecting RDBs. The Gatewa y designed here use the ObjectPro/ODB developed by Institute for Information I ndustry (III) as an example DBMS. The theory developed in this research, howev er,is generally applicable to other OODBMSs. In between the Gateway and RDBs, there is an interface command converter ODBC ( Open DataBase Connectivity ). W e adopt ODBC because of its popularity and supporting for most existing RDBMSs . In this thesis, we discuss schema translation ( translation between OODB sch ema and RDB schema), query translation ( translating OODB query to standard SQ L), and data transformation ( transforming RDB tuples to OODB objects).

The thesis presents methodology of creating whole-fish dermoplastic models. It is primarily intended for teachers of natural history and biology. The results are based on mapping out both modern and traditional methods of fish taxidermy. By empirical verification and introduction of new methods, a comprehensive manual of fish taxidermy was created. It can serve as a useful didactic tool. Methodology also describes the issue of obtaining and preserving fish specimen. Profound knowledge of fish anatomy is a necessary prerequisite for specimen taxidermy, thus methodology also includes anatomical overview and guidelines for fish anatomical dissection. The output of the practical part of the thesis are dermoplastic fish models which became part of the specimen collection at the Department of Biology and Environmental Studies at the Faculty of Pedagogics at Charles University, where they are meant to be used for educational purposes. Methodological part of the thesis evaluates the experience gained during the process of model creation. Certain recommendations regarding suitability of particular fish species for taxidermy, material and tools required, choice of method and its advantages and disadvantages, were made. The thesis discusses several specific technologies, such as producing eyes for the...

Full textAbstract:
When considering fish as food, first of all the n-3 LC-PUFA, particularly EPA and DHA are in focus. Furthermore, it gets obvious that the proteins and peptides in fish have not only a high nutritional value but also impact on human health issues. In addition, fish can be considered as a good source of several minerals, vitamins and micronutrients. The overall aim of the thesis was to highlight different factors which influence nutritional quality of fish and to focus on the nutritional value of some commercially important river fish species from the Czech Republic. Moreover, to examine different sustainable alternatives to replace FO and FM in the feed of carnivorous. According to our results, there were some variation of FA composition in the selected seven freshwater fish species from the Czech Republic, depending on the natural habitat and differences in feed and its availability. Simultaneously, we observed a very favourable FA composition with good proportions of n-3 PUFA, including EPA and DHA in all analyzed species which reflects the composition of the natural diet. Consequently, the values of both index of atherogenicity (IA) and index of thrombogenicity (IT) were low and close to the values of the so-called Eskimo diet, which is related to very low incidences of the coronary heart disease. According to our findings we concluded that the chosen species have a standard protein content, minimum carbohydrates and relatively low contents of fat, which can, however, vary to some degree in various localities, most probably related to the availability and composition of the feed. Due to the combination of the drastic increase in the need for aquaculture feed as well as decline in the sources of FM and FO, utilization of alternative sources received more attention. Based on our result, it is possible to replace VO by yeast oil produced from lingocellulose in the feed of Arctic char (Salvelinus alpinus). There were no significant differences in the study, regarding weight gain, feed conversation ratio, condition factor and hepatosomatic index between the control and the yeast oil fed group. According to the results of another study, partial (25% of pellet replaced live house cricket, 25% of pellet replaced by superworm, combination of 12.5% crude energy of each group) or total replacement (50% of each) of house cricket and superworm for FM in the commercial diet of rainbow trout indicated no negative effects on growth, survival, FCR and gross energy utilization. Inclusion of insect was connected with lower content of nutritionally valuable n-3 FAs (EPA and DHA). In our study total replacement showed the mixture of insects, caused the better growth performance compared to the commercial feed of similar energy value as insects are good live food for salmonids. With increase in the proportion of insect's inclusion in the feed of fish, changes in the sensory properties, texture and colour of fish flesh was in a way that showed less acceptability and preference by consumers. Replacement of 25% FM by a mixture of insect meal including house cricket- (Acheta domesticus) and superworm- (Zophobas morio) meal (with an amino acid adjustment) in the diet of perch, on survival, growth, feed conversion with special emphasis on lipid changes and composition showed FA composition of the fish fillet was only affected to a minor extent. However, the lower growth performance in the fish group fed by insect indicated lower nutritional value and digestibility of the feed along with the taste of the feed. Interestingly, the significant increase of 18:2 n-6 in the group fed by insect was due to the higher content of this FA in both insects and subsequently in the experimental diet which from the nutritional point of view this change was neglectable.

Taxonomic and morphological evaluation of the material of monogeneans parasitic in the cichlid fishes (Cichla monoculus, Cichlasoma amazonarum, Satanoperca jurupari) from the Amazon River in Peru provided new data on the occurrence of 12 species of Dactylogyridae (10 species), Gyrodactylidae (1 species) and Microcotylidae (1 species). Four of them probably represent species new for science; one of them has already been described and a new genus has been proposed to accommodate it. Six species are reported from Peru for the first time and cichlids studied represent new hosts.
