In this study, rice straw (Oryza sativa L.) fibril and fibril aggregates (RSFs) material isolated by high intensity ultrasonication (HIUS) was used as reinforcement in an RSFs/Polypropylene (PP) nanocomposites. The morphology of RSFs was investigated by scanning electron microscopy (SEM). The mechanical properties were evaluated by tensile test. The fourier transform infrared spectroscopy (FTIR) test was also performed to investigate the interface compatibility between RSFs and PP matrix. Results indicated that the tensile strength of RSFs/PP nanocomposites increased with increasing cycle time of extruder from 10 min to 30 min at 180°C. The maximum value of tensile strength was 31.2 MPa appeared at the conditions of 190°C and cycle 20 min. The elastic modulus increased by adding 5 wt% RSFs into the PP/MAPP matrix. However, there was no distinct difference of elongation in RSFs/PP nanocomposites at different extruder conditions. The RSFs embedded into the PP/MAPP matrix and exhibited better interaction by FTIR test.

Ribosomal silencing factor S (RsfS) is a conserved protein that plays a role in the mechanisms of ribosome shutdown and cell survival during starvation. Recent studies demonstrated the involvement of RsfS in the biogenesis of the large ribosomal subunit. RsfS binds to the uL14 ribosomal protein on the large ribosomal subunit and prevents its association with the small subunit. Here, we estimated the contribution of RsfS amino acid side chains at the interface between RsfS and uL14 to RsfS anti-association function in Staphylococcus aureus through in vitro experiments: centrifugation in sucrose gradient profiles and an S. aureus cell-free system assay. The detected critical Y98 amino acid on the RsfS surface might become a new potential target for pharmacological drug development and treatment of S. aureus infections.

Approximately 30% of Minnesota's residents rely on onsite technologies for their wastewater treatment. There is a growing need for ‘alternative, technologies to aid in treatment for difficult sites and sensitive environmental areas. Recirculating sand filters (RSFs) have been used since the 1970s for small communities with flows >20,000 L per day, but use for small flow application (<5,000 L/d) has been growing due to its small land use requirement. A research site was developed in southern Minnesota in 1995 to test alternative technologies, including two RSFs. In addition, in 1998, two RSFs were added to existing residential soil treatment systems that were having problems because of inadequate separation and fill soil conditions. All RSFs in this study used 0.6 metres of coarse sand for treatment, were loaded at approximately 204 L per day per square metre (5 gallons per square foot per day) and a recirculation rate of 5:1. All RSFs have effectively reduced Biochemical Oxygen Demand (BOD5), Total Suspended Solids (TSS), Fecal Coliform (FC) and Nutrients (nitrogen and phosphorus). These systems are able to achieve secondary effluent treatment levels for BOD5 and TSS. The median FC reduction was 90% with a value of 5.7 E4 cfu/100 mL, indicating additional treatment is necessary to protect health and the environment. The RSFs consistently removed 25% or more total phosphorus (TP) and 40% or more total nitrogen (TN). The RSFs did not show significantly decreased performance during the winter months. Two of the RSFs receiving rather high strength domestic waste were able to reduce a greater percentage of total nitrogen, indicated that the addition of carbon from the high strength waste is a benefit resulting in greater TN removal.

Rice straw (Oryza sativa L.) pulp was treated by high intensity homogenizer to make fibril and fibril aggregates. The rice straw fibril and fibril aggregates (RSFs) material was used as reinforcement in a RSFs/ Poly (vinyl alcohol) (PVA) nanocomposite that prepared by film casting. The diameter distribution of RSFs was investigated by laser diameter instrument (LDI) and its crystallinity was evaluated by wide angle X-ray diffraction (WAXD). The morphological of RSFs was investigated by scanning electron microscopy (SEM). The mechanical properties were measured by tensile test and the dynamic mechanics analysis (DMA), thermal stability tests, i.e., differential scanning calorimetry (DSC) and thermogravimetric analysis (TG) and the Fourier transform infrared spectroscopy (FTIR) test were also performed, respectively.

Bound dissipative solitons are numerically studied by implementing strong Raman self-frequency shift (RSFS) in an all-normal-dispersion (ANDi) Yb-doped fiber laser. Results demonstrated that overstrong RSFS had no filter-like effect in the ANDi fiber laser when a bandpass filter was present in the intracavity. However, overstrong RSFS could cause the bandpass filter to destabilize the ANDi fiber laser. For the first time in the field, we have demonstrated that strong RSFS could destabilize bound DS pulses and generate noise-like bound pulses. Furthermore, the generation mechanism of destabilized noise-like bound pulses in the fiber laser with intracavity filter is different from the noise-like pulses in the fiber lasers without a bandpass filter.

Abstract Environmental quality standards for surface waters have been significantly expanded through recent amendments to German regulations. Limit values are only established for applicable regulations if the water is indicated for certain uses, e.g. abstraction of irrigation water. Nevertheless, surface water bodies are often used for hygiene-sensitive purposes. In the course of climate change, stronger precipitation events will occur, which may lead to more frequent loading and discharge of combined sewer overflow (CSO) into surface water bodies. Retention soil filters (RSFs) are attracting attention as an extensive treatment technology for CSO and additional wastewater treatment. This study examined large-scale RSFs for CSO treatment, as well as the effectiveness of RSFs as a fourth purification stage. An RSF test facility was established at a municipal wastewater treatment plant (WWTP), consisting three semi-technical RSFs that were fed exclusively with treated water from the WWTP. The reduction of microorganisms mostly occurred within the first centimeters of the RSFs. For most hygienic-microbiological parameters, a 1–2 log unit reduction could be detected in addition to the reduction within the WWTP. Antibiotic-resistant bacteria were reduced to the same extent. Investigation of the large-scale RSFs showed that a flow rate reduced by half corresponded to better reduction performances.

Breast cancer is a common cancer in female. Accurate and early detection of breast cancer can play a vital role in treatment. This paper presents and evaluates a thermogram based Computer-Aided Detection (CAD) system for the detection of breast cancer. In this CAD system, the Random Subset Feature Selection (RSFS) algorithm and hybrid of minimum Redundancy Maximum Relevance (mRMR) algorithm and Genetic Algorithm (GA) with RSFS algorithm are utilized for feature selection. In addition, the Support Vector Machine (SVM) and k-Nearest Neighbors (kNN) algorithms are utilized as classifier algorithm. The proposed CAD system is verified using MATLAB 2017 and a dataset that is composed of breast images from 78 patients. The implementation results demonstrate that using RSFS algorithm for feature selection and kNN and SVM algorithms as classifier have accuracy of 85.36% and 75%, and sensitivity of 94.11% and 79.31%, respectively. In addition, using hybrid GA and RSFS algorithm for feature selection and kNN and SVM algorithms as classifier have accuracy of 83.87% and 69.56%, and sensitivity of 96% and 81.81%, respectively, and using hybrid mRMR and RSFS algorithms for feature selection and kNN and SVM algorithms as classifier have accuracy of 77.41% and 73.07%, and sensitivity of 98% and 72.72%, respectively.

In surface roughness measurements, the presence of spikes in the primary profile can disable a normal filter from extracting the shape and waviness components. The robust spline filter (RSF) has been proposed to solve this problem. However, because ISO 16610-32, an RSF standard, has a significant deficiency, it was withdrawn in the Technical Specifications stage. The other proposed RSFs only show the method and a few examples with normal roughness and spike. Therefore, because the characteristics of each RSF have not been clarified, which RSF should be used for which primary profiles is not clear. This is one of the reasons for the delay in establishing ISO. In addition, the measurement sites need the establishment of robust spline filter selection guidelines. Therefore, in this paper, the characteristics of RSFs are clarified. Additionally, the points to be considered in using RSFs are summarized. Finally, the filter that should be selected for the specific application is identified. These results are expected to contribute to the widespread use of RSFs in the industrial world, avoid confusion at the measurement site, and help establish a new RSF standard.

This study addresses the problem of restricted ability for large-scale monitoring due to the limited cruising time of unmanned aerial vehicles (UAV) by identifying an optimal leaf ChlorophyII content (LCC) inversion machine learning model at different scales and under different parameterization schemes based on simultaneous observations of ground sampling, UAV flight, and satellite imagery. The following results emerged: (1) The correlation coefficient between most remote sensing features (RSFs) and LCC increased as the remote scale expanded; thus, the scale error caused by the random position difference between GPS and measuring equipment should be considered in field sampling observations. (2) The LCC simulation accuracy of the UAV multi-spectral camera using four machine learning algorithms was ExtraTree > GradientBoost > AdaBoost > RandomForest, and the 20- and 30-pixel scales had better accuracy than the 10-pixel scale, while the accuracy for three feature combination schemes ranked combination of extremely significantly correlated RSFs > combination of significantly correlated and above RSFs > combination of all features. ExtraTree was confirmed as the optimal model with the feature combination of scheme 2 at the 20-pixel scale. (3) Of the Sentinel-2 RSFs, 27 of 28 were extremely significantly correlated with LCC, while original band reflectance was negatively correlated, and VIs were positively correlated. (4) The LCC simulation accuracy of the four machine learning algorithms ranked as ExtraTree > GradientBoost > RandomForest > AdaBoost. In a comparison of two parameterization schemes, scheme 1 had better accuracy, while ExtraTree was the best algorithm, with 11 band reflectance as input RSFs; the RMSE values for the training and testing data sets of 0.7213 and 1.7198, respectively.

Previous studies on residential satisfaction factors (RSFs) overlooked residents’ psychological needs. To bridge this gap, we linked RSFs to the Modified Maslow’s Hierarchy of Human Needs (MMHN) through a three-step qualitative and quantitative integrated analysis. First, RSFs were derived from the analysis of previous studies. Second, through an analytic hierarchy process and a focus group interview, RSFs and the MMHN were linked. Third, the MMHN-based model was applied to data from the 2020 Korea Housing Survey, and classification and regression tree analysis were performed to derive significant factors, which were then compared to significant factors from the conventional model. The comparative analysis results of the conventional and MMHN-based models were as follows: (1) The MMHN-based model presented significant factors in all five stages of human needs, reflecting various human needs. (2) The MMHN-based model assessed the housing needs of residents in the non-capital region in more detail. (3) The MMHN-based model investigated the differences in residential satisfaction factors between metropolitan and non-metropolitan regions more clearly. (4) Two factors influencing safety needs important in all regions in both models were deemed crucial for residential satisfaction. This study could support the customization of regional housing policies according to unique needs and life circumstances by region.

Actuellement, en raison de l'utilisation active et parfois incontrôlée des antibiotiques, le nombre de souches de S. aureus présentant une résistance élevée aux médicaments antibactériens augmente chaque année. Les cellules persistantes jouent un rôle important dans ce processus. Même en l'absence de résistance aux antibiotiques, ces cellules survivent, provoquant des infections récurrentes, car elles ont bloqué les sites de liaison de la plupart des médicaments thérapeutiques affectant le ribosome de S. aureus. Par conséquent, la lutte contre les mécanismes cellulaires responsables de la transition des cellules vers un état persistant est une priorité pour la recherche. L'un de ces mécanismes est lié au fonctionnement du facteur RsfS. Dans cette étude, la première structure cryo-EM à résolution de 3.2 Å du complexe 50S et RsfS et la structure X-ray à résolution de 2.3 Å du complexe RsfS et uL14 ont été obtenues. La région de l'acide aminé Tyr 98 de RsfS est un site critique pour la préservation des fonctions anti-associatives du facteur RsfS de S. aureus. Les résultats obtenus dans ce projet pourraient servir de base au développement de nouveaux types de médicaments capables d'atténuer les propriétés pathogènes de S. aureus
Currently, due to the active and sometimes uncontrolled use of antibiotics, the number of S. aureus strains with high resistance to antibacterial drugs increases every year. Persister cells play an important role in this process. Even in the absence of antibiotic resistance, these cells survive, causing recurrent infections, since they have blocked the binding sites of most therapeutic drugs affecting the S. aureus ribosome. Therefore, combating the cellular mechanisms responsible for the transition of cells to a persister state is a priority for research. One such mechanism is related to the functioning of the RsfS factor. In this study, the first 3.2 Å resolution cryo-EM structure of the 50S and RsfS complex and X-ray 2.3 Å resolution structure of the RsfS and uL14 complex were obtained. The RsfS Tyr 98 amino acid region is a critical site for preserving the anti-associative functions of the S. aureus RsfS factor. The obtained in this work results could form the basis for the development of new types of drugs capable of attenuating the pathogenic properties of S. aureus

Nesta dissertação iremos analisar a dinâmica do crescimento para modelos de autômatos celulares. Uma vez que a evolução cria uma superfície de fractal, mostraremos que a variação da rugosidade pode ser apresentada em uma expressão simples que combina duas componentes: a distribuição de probabilidade das configurações da superfície e as regras que define um autômato celular. A partir destas considerações investigaremos uma das variações do modelo RestrictedSolid-On-Solid(RSOS) em 1+1 dimensão e as propriedades da rugosidade, assim como as propriedades gerais que a mesma deve satisfazer. _________________________________________________________________________________________________ ABSTRACT
This dissertation will examine the growth dynamics for cellular automata models. Since the evolution creates a fractal surface, we show that the variations of roughness can be presented in simple expression that combine two combines: the probability distribution of the surface configurations and the rules that define a cellular automata. From these considerations we will investigate one of the variations of the Restricted Solid-On-Solid (RSOS) model in 1+1 dimensions and properties of the roughness, as well as the general properties that it must satisfy.

ENGLISH ABSTRACT: In order to facilitate the creation of complex and robust RSFQ digital logic circuits an extensive library of electronic design automation (EDA) tools is a necessity. It is the aim of this work to introduce various methods to improve the current state of EDA in RSFQ circuit design. Firstly, Monte Carlo methods such as Latin Hypercube sampling and Sobol sequences are applied for their variance reduction abilities in approximating circuit yield. In addition, artificial neural networks are also investigated for their applicability in modeling the parameter-yield space. Secondly, a novel technique for circuit functional testing using automated state machine extraction is presented, which greatly simplifies the logical verification of a circuit. This method is also used, along with critical timing extraction, to automatically generate Hardware Description Language(HDL) models which can be used for high level circuit design. Lastly, the Greedy Local search, Simulated Annealing and Genetic Algorithm meta-heuristics were statistically compared in a novel manner using a yield model provided by artificial neural networks. This is done to ascertain their performance in optimising RSFQ circuits in relation to yield. The variance reduction techniques of Latin Hypercube Sampling and Sobol sequences were shown to be beneficial for the use with RSFQ circuits. For optimisation purposes the use of Simulated Annealing and Genetic Algorithms were shown to improve circuit optimisation for possible multi-modal search spaces. An HDL model is also successfully generated from a complex RSFQ circuit for use in high level circuit design which includes critical timing and propagation latency. All the techniques presented in this study form part of a software library that can be further refined and extended in future work.

Wireless Sensors Network (WSN) based systems, are traditionally used to monitor events in places with limited human access. A WSN is formed by a group of devices called sensors node, each responsible for transporting monitored data to a certain destination and performing other programmed tasks in order to comply with further objectives of the proposed system. Since power consumption is one of the main challenges associated to the use of WSNs, techniques to minimize such energy consumption of a complete WSN or even in one sensor node, have been object of extended research. Maximizing the lifetime of the network can be obtained throughout better data package management or by reducing the adopted transmission power, for example. It is important to note that this optimization is limited by the process delay of the sensor node itself, as well as by interference causing an increased error rate, which itself affects the data packet transmission between source and destination. In this context, this work proposes a technique able to stimulate individually tailored behavioral changes regarding the data packets analysis and the consumption energy thought certain transmission path in each sensor node. It called Path Energy Control Technique (PECT).In more details, the PECT is based on the adjustment of the power transmission from on the analysis of the Received Signal Strength Indicator (RSSI) and a quality metric is assigned to paths, where the data packets flow between nodes. This metric is calculate from the efficiency in the data packet’s reception, from the disturbance in the path, as well as the data packet sending frequency due the number of sensors nodes for the specific neighborhood. It should be mention the PECT technique will be represented by a algorithm to be development in this work which will be implemented at application level, guarantying portability, independent from the hardware used for the WSN. In addition, the PECT is able to manage the data transmission frequency and to support different network topologies, including multipath topologies. Finally, the PECT technique is validated through simulations and the results were obtained from the evaluation of the efficiency. The techniques’ robustness is analyzed and compared with other techniques from literature.
Sistemas baseados em Rede de Sensores Sem Fio (RSSF) são tradicionalmente utilizados para monitorar eventos em áreas onde o acesso é limitado. Uma RSSF é formada por um conjunto de dispositivos chamados de nodos sensores, os quais têm a missão de transportar os dados monitorados para um determinado destino e executar as tarefas programadas para cumprir com os objetivos do sistema proposto. Técnicas que visam minimizar o consumo de energia de RSSF ou até mesmo de apenas um nodo sensor vêm sendo objeto de várias pesquisas, uma vez que a energia representa um dos desafios relacionados ao uso de RSSF. A maximização da vida útil da rede pode ser obtida a partir de uma melhor gestão dos pacotes de dados ou até mesmo a partir da redução da potência de transmissão adotada, por exemplo. Note que essa maximização é limitada no momento em que se observa um aumento da taxa de erros em função da interferência que, por sua vez, afeta a transmissão dos pacotes de dados entre a origem e o destino, bem como em função do próprio atraso do processamento no nodo sensor. Neste contexto, o presente trabalho propõe uma técnica capaz de modificar individualmente o comportamento de cada nodo sensor a partir da análise dos pacotes de dados e da energia consumida por um determinado caminho de transmissão Path Energy Control Technique (PECT).Em mais detalhes, a técnica baseia-se no ajuste da potência de transmissão a partir da análise do Received Signal Strength Indicator (RSSI) e de uma métrica de qualidade que será atribuída ao caminho que os dados trafegam na rede entre os nodos. Essa métrica é calculada a partir da eficiência da recepção dos pacotes, da perturbação no caminho dos dados e da frequência de envio dos pacotes de dados em função do número de nodos sensores da vizinhança. Convém mencionar que a PECT foi representada por um algoritmo a ser desenvolvido, e poderá ser implementada no nível de aplicação, o que, por sua vez, garante a portabilidade e o uso independente do hardware que está sendo utilizado para a RSSF. Além disso, a PECT é capaz de gerenciar a frequência de envio de dados e de suportar diferentes topologias de redes, incluindo as topologias de multipath. Finalmente, a técnica será validada através de simulações, e os resultados obtidos na avaliação da eficiência e da robustez da mesma, serão analisados e comparados com outras técnicas presentes na literatura.

Les systèmes de télécommunication de type radio logicielle ou "Software Defined Radio" (SDR) exploitent les techniques numériques qui permettent leur reconfigurabilité, que ce soit en termes de fréquence, de bande passante utilisée, ou de méthode de modulation/démodulation des signaux. Ceux-ci nécessitent des architectures permettant la numérisation des signaux analogiques RF à des fréquences d'échantillonnage de plusieurs dizaines de GHz, avec des bandes passantes de plusieurs dizaines de MHz et une résolution supérieure à 10 bits. Ces objectifs sont très difficiles à atteindre avec la technologie actuelle des semi-conducteurs. La logique à quantum de flux magnétique ou logique "Rapid Single-Flux-Quantum" (RSFQ) se présente comme un candidat séduisant pour la conception de tels systèmes.En effet, celle-ci permet d'atteindre des fréquences d'horloge de plusieurs centaines de GHz pour une consommation d'environ 100 nW par porte logique. Le travail de thèse a consisté en la réalisation d'un prototype de chaîne de réception RF analogique-numérique en technologie RSFQ. L'étude et la conception des différents blocs la constituant comme le convertisseur analogique-numérique et ceux de traitement du signal numérisé en aval a été réalisée. Les premiers résultats expérimentaux confirment la fonctionnalité des cellules RSFQ de base constituant le bloc de traitement numérique. La difficulté à faire fonctionner expérimentalement les blocs plus complexes a soulevé la question de la sensibilité des cellules RSFQ aux perturbations magnétiques extérieures. Cette problématique a été étudiée sur des circuits RSFQ simples et a permis de conclure qu'un champ magnétique externe de quelques dizaines de $mu$T était suffisant pour dégrader le fonctionnement de tels circuits. Une solution de prise en compte des effets d'un champ magnétique externe dans le simulateur utilisé a été développée pour anticiper ces problèmes dès la conception. Celle-ci a été validée expérimentalement avec un Superconducting Quantum Interference Device (SQUID)
Information and telecommunication Software Defined Radio (SDR) systems are mainly based on digital techniques, which enable to easily reconfigure them, in terms of frequency, bandwidth and modulation techniques. They can process the information entirely in a digital way, by directly sampling the input RF signal and require analog-to-digital converters with strong performances. Indeed, SDR systems have to work at sampling frequencies of several tens of GHz, with large bandwidths and a suitable resolution ($geq$ 10 bits). Rapid-Single-Flux-Quantum logic (RSFQ) seems to be an interesting solution to design such systems. This technology can reach clock frequencies of several hundreds of GHz with a power consumption of only 100 nW per logic gate. This work deals with the design of a superconductive RF front-end receiver based on RSFQ technology. The study of the different parts of the chain was done, such as the analog-to-digital converter and the signal processing part of the digital signal. Experimental results confirm that all simple RSFQ cells work with correct margins. Complex circuits work with more difficulty, raising the issue of the sensitivity of RSFQ cells to external magnetic disturbances. This point was studied on basic RSFQ cicuits and shows that a magnetic field of about 10 $mu$T is sufficient to spoil the operation of the circuit. Moreover, a solution to take into account magnetic effects in the simulation of the circuits was developed and experimentally validated on a Superconducting Quantum Interference Device (SQUID)

AbstractRecommender systems are increasingly being used for many purposes. This is creating a deeply problematic situation. Recommender systems are likely to be wrong when used for these purposes because there are distorting forces working against them. RS’s are based on past evaluative standards which will often not align with current evaluative standards. RS’s algorithms must reduce everything to computable information – which will often, in these cases, be incorrect and will leave out information that we normally consider to be important for such evaluations. The algorithms powering these RSs also must use proxies for the evaluative ‘good’. These proxies are not equal to the ‘good’ and therefore will often go off track. Finally, these algorithms are opaque. We do not have access to the considerations that lead to a particular recommendation. Without these considerations we are taking the machine’s output on faith. These algorithms also have the potential to modify how we evaluate. YouTube has modified its algorithm explicitly to ‘expand our tastes’. This is an extraordinary amount of power – and one that if my first argument goes through, is likely to take us away from the good. This influences our behavior which feeds back into the algorithms that make recommendations. It is important that we establish some meaningful human control over this process before we lose control over the evaluative.

Fitness-For-Service (FFS) assessment procedure can be also used to determine a reduced Maximum Allowable Working Pressure (MAWP) for cylindrical and spherical pressure vessel with local metal loss. A reduced MAWP is calculated from the Remaining Strength Factor (RSF). RSF is defined as ratio between plastic collapse load of the damaged component and that of the undamaged component. RSF needs to be calculated accurately in order to continue the damaged component in service safely. In this paper, RSFs of the damaged components with variously-shaped local metal loss were investigated. Especially, effects of circumferential width of local metal loss for cylindrical pressure vessel are investigated by both hydrostatic burst test and finite element analysis (FEA). The configurations of the local metal loss are rectangle. The longitudinal length and minimum thickness are fixed. FEA using the criterion proposed by Miyazaki et al. is effective to estimate fracture ductility under the multi-axial stress condition accurately, and effects of circumferential width is evaluated. In addition, RSF for spherical pressure vessel with relatively large diameter/thickness ratio was calculated by finite element analysis. Both results were compared to the calculation results using the equation in API 579-1/ASME FFS-1. The FFS assessment procedure is validated as conservative assessment experimentally and numerically.

Em redes de sensores sem fio (RSSFs) a eficiência energética é o principal problema de pesquisa. Tendo em vista a limitada reserva de energia dos nos sensores e o alto custo energético para transmitir e receber dados, definir a quantidade de dados de controle necessários à manutenção da RSSF é um grande problema. Este trabalho apresenta o MAC-RSPC, uma proposta de protocolo MAC para Redução de Sobrecarga de Pacotes de Controle, destinado a RSSFs multicanais e homogeneas. O MAC-RSPC segue a abordagem cross-layer e visa a eficiência energética. A técnica de redução de sobrecarga visa diminuir a quantidade de dados de controle que circulam na rede sem, no entanto, diminuir a qualidade dos dados disponíveis para manutenção da estrutura da rede e construção de rotas.

A Internet das Coisas (IoT - Internet of Things) é uma inovação tecnológica que tem se tornado bastante atrativa no âmbito comercial, industrial e residencial. Por conta disso, houve uma expansão no desenvolvimento de mecanismos de comunicação eficientes e desenvolvimento de aplicações em Redes de Sensores Sem Fio (RSSF). O conjunto de normas IEEE 802.15.4 e ZigBee forma uma pilha adequada de protocolos para implantação de RSSFs. Esse conjunto de normas especifica uma topologia especial peer-to-peer chamada cluster-tree, apontada como uma das topologias mais apropriadas para implantação de RSSFs de larga escala. Entretanto, a ocorrência de congestionamentos evidencia-se como um dos maiores desafios de redes cluster-tree, tornando necessário o desenvolvimento de mecanismos eficientes para mitigar este problema, sem comprometer a integridade dos dados. Este artigo propõe a utilização de um mecanismo local de filtragem de dados eficiente como forma de evitar ou postergar congestionamentos para RSSFs cluster-tree, evitando reconfigurações de rede e melhorando métricas importantes, tais como atrasos de comunicação fim-a-fim e perda de pacotes. Os resultados mostram que a implementação de mecanismos de filtragem local nos nós sensores pode fornecer qualidade de serviço para o fluxo de monitoramento, evitando a execução de mecanismos de controle e reconfiguração de redes.

Este artigo apresenta o Sensoriamento Overlay Seguro (SOS). O SOS constrói uma Rede Overlay (RO) sobre uma Rede de Sensor Sem Fio (RSSF). Ao estabelecer e monitorar rotas alternativas, o SOS é capaz de encontrar rotas mais seguras que as fornecidas pelo protocolo de roteamento padrão. Os resultados indicam que o SOS é: 1) eficaz no aumento da taxa de entrega de mensagens em redes sob ataques de negação de serviço e 2) eficiente em termos de consumo de energia. Até onde sabemos, o SOS é o primeiro mecanismo de segurança baseado em ROs para RSSFs.

Redes de Sensores Sem Fio (RSSF) usam ciclos de trabalho como estratégia para economizar energia. O atraso de propagação (sleep-delay) é uma consequência negativa desse modo de operação, aumentando a latência fim-a-fim. Apresenta-se aqui o Split-MAC: um protocolo assíncrono de baixa energia e latência reduzida para RSSFs. Ele reúne funções de controle de acesso ao meio e de roteamento, e emprega estratégias para obter baixa latência: comunicação anycast, um esquema de reserva de canal para transmitir dados de maneira encadeada e transmissão simultânea de segmentos de dados. Simulações foram realizadas para comparar este protocolo com outros da literatura. O Split-MAC demonstrou superioridade frente aos outros protocolos testados, reduzindo a latência em pelo menos 30%.

As energy usage across the world continues to rise, there is a strong need to develop new methods for energy conservation and power generation, particularly approaches that have less environmental impacts. Although human power is not ideal in terms of life cycle costs [1], there are promising application areas for human power in emerging regions where electric power is either not available or not affordable [2]. There is also untapped potential for harnessing human power at most fitness facilities. This paper focuses on the feasibility of capturing this energy at fitness facilities, particularly the Recreational Sports Facility (RSF) at University of California, Berkeley, which averages over 2,800 patrons per day. In particular, we estimated that patrons using 28 elliptical machines would supply approximately 10,000 kWh into the electric grid over a year. This amounts to only 0.7% of the RSF’s total energy needs, but is valuable nonetheless. An additional benefit in human power generation is its positive social impact. A survey of the RSF users has evinced remarkable enthusiasm for implementing energy generation technology into the facility, both as a power generation tool and as an educational resource. This paper will also address the social benefits of human power generation technology in the gym.

As normas IEEE 802.15.4 e ZigBee definem a pilha de protocolos amplamente utilizada na operação de Redes de Sensores sem Fio (RSSF). A topologia cluster-tree, suportada por estas normas, oferece recursos como escalabilidade, sendo apontada pela literatura como a mais adequada para a implementação de aplicações de RSSFs em larga escala. Entretanto, essas redes podem sofrer com congestionamentos e atrasos devido aos seus diferentes padrões de tráfego. Por um lado, são usualmente priorizadas as mensagens do tráfego de monitoramento geradas por nós sensores, que seguem em direção ao coordenador da rede (tráfego upstream); por outro, sofrem maiores atrasos as mensagens de controle que seguem o tráfego inverso (tráfego downstream). Este artigo propõe um mecanismo eficiente para a rápida disseminação do tráfego de controle em RSSFs cluster- tree. A ideia principal consiste em combinar um esquema de escalonamento híbrido periódico, com a definição de janelas de oportunidade Top-Down, com um esquema de configuração adequada dos parâmetros CSMA-CA (Carrier Sense Multiple Access with Collision Avoidance) para os nós coordenadores, a fim de possibilitar uma rápida disseminação das mensagens de controle, sem gerar impactos relevantes para o típico tráfego de monitoramento. Resultados de simulações mostram que a definição de janelas de oportunidades Top-Down, aliada com uma adequada configuração de valores macMinBE e macMaxBE para nós coordenadores, podem reduzir significativamente os atrasos de comunicação e aumentar a taxa de entrega de mensagens de controle, sem interferir de forma relevante nas métricas do tráfego de monitoramento, mesmo em cenários de grande densidade de nós sensores.

Normally, one link of the four-bar linkage is fixed to the frame; another supplies the input; the motion of the third one with respect to the base is the output. A novel application of the four-bar linkage is proposed that a parallelogram mechanism is applied to be a rolling robot for which there is neither a constant base nor a constant output. Four sides take turns to be the support link and an adjacent link of the support one is regarded as the output in turn. The rolling motion is actuated by an internal angle change which is supplied by the rocker oscillation of a crank-rocker mechanism, not a motor directly. The unidirectional rotation of the motor simplifies the control system. A planar 4R parallelogram is suggested to roll straight under the driving of a planar 4R crank-rocker mechanism. For turning, a spatial RSRS quadrilateral is presented to roll and turn driven by a spatial RSUS crank-rocker mechanism. The principle of tipping and rolling are explained. Simulations testify the parameter design of the driving rank-rocker mechanism. An experimental prototype is fabricated to verify the feasibility of the concept.

RNA silencing is a defense mechanism that functions against virus infection and involves sequence-specific degradation of viral RNA. Diverse RNA and DNA viruses of plants encode RNA silencing suppressors (RSSs), which, in addition to their role in viral counterdefense, were implicated in the efficient accumulation of viral RNAs, virus transport, pathogenesis, and determination of the virus host range. Despite rapidly growing understanding of the mechanisms of RNA silencing suppression, systematic analysis of the roles played by diverse RSSs in virus biology and pathology is yet to be completed. Our research was aimed at conducting such analysis for two grapevine viruses, Grapevine virus A (GVA) and Grapevine leafroll-associated virus-2 (GLRaV- 2). Our major achievements on the previous cycle of BARD funding are as follows. 1. GVA and GLRaV-2 were engineered into efficient gene expression and silencing vectors for grapevine. The efficient techniques for grapevine infection resulting in systemic expression or silencing of the recombinant genes were developed. Therefore, GVA and GLRaV-2 were rendered into powerful tools of grapevine virology and functional genomics. 2. The GVA and GLRaV-2 RSSs, p10 and p24, respectively, were identified, and their roles in viral pathogenesis were determined. In particular, we found that p10 functions in suppression and pathogenesis are genetically separable. 3. We revealed that p10 is a self-interactive protein that is targeted to the nucleus. In contrast, p24 mechanism involves binding small interfering RNAs in the cytoplasm. We have also demonstrated that p10 is relatively weak, whereas p24 is extremely strong enhancer of the viral agroinfection. 4. We found that, in addition to the dedicated RSSs, GVA and GLRaV-2 counterdefenses involve ORF1 product and leader proteases, respectively. 5. We have teamed up with Dr. Koonin and Dr. Falnes groups to study the evolution and function of the AlkB domain presents in GVA and many other plant viruses. It was demonstrated that viral AlkBs are RNA-specific demethylases thus providing critical support for the biological relevance of the novel process of AlkB-mediated RNA repair.

The general goal was to identify, map, and tag, with DNA markers, segments of chromosomes of a wild species (wild emmer wheat, the progenitor of cultivated wheat) determining the number, chromosomal locations, interactions, and effects of genes that control quantitative traits when transferred to a cultivated plant (bread wheat). Slight modifications were introduced and not all objectives could be completed within the human and financial resources available, as noted with the specific objectives listed below: 1. To identify the genetic contribution of each of the available wild emmer chromosome-arm substitution lines (CASLs) in the bread wheat cultivar Bethlehem for quantitative traits, including grain yield and its components and grain protein concentration and yield, and the effect of major loci affecting the quality of end-use products. [The quality of end-use products was not analyzed.] 2. To determine the extent and nature of genetic interactions (epistatic effects) between and within homoeologous groups 1 and 7 for the chromosome arms carrying "wild" and "cultivated" alleles as expressed in grain and protein yields and other quantitative traits. [Two experiments were successful, grain protein concentration could not be measured; data are partially analyzed.] 3. To derive recombinant substitution lines (RSLs) for the chromosome arms of homoeologous groups 1 and 7 that were found previously to promote grain and protein yields of cultivated wheat. [The selection of groups 1 and 7 tons based on grain yield in pot experiments. After project began, it was decided also to derive RSLs for the available arms of homoeologous group 4 (4AS and 4BL), based on the apparent importance of chromosome group 4, based on early field trials of the CASLs.] 4. To characterize the RSLs for quantitative traits as in objective 1 and map and tag chromosome segments producing significant effects (quantitative trait loci, QTLs by RFLP markers. [Producing a large population of RSLs for each chromosome arm and mapping them proved more difficult than anticipated, low numbers of RSLs were obtained for two of the chromosome arms.] 5. To construct recombination genetic maps of chromosomes of homoeologous groups 1 and 7 and to compare them to existing maps of wheat and other cereals [Genetic maps are not complete for homoeologous groups 4 and 7.] The rationale for this project is that wild species have characteristics that would be valuable if transferred to a crop plant. We demonstrated the sequence of chromosome manipulations and genetic tests needed to confirm this potential value and enhance transfer. This research has shown that a wild tetraploid species harbors genetic variability for quantitative traits that is interactive and not simply additive when introduced into a common genetic background. Chromosomal segments from several chromosome arms improve yield and protein in wheat but their effect is presumably enhanced when combination of genes from several segments are integrated into a single genotype in order to achieve the benefits of genes from the wild species. The interaction between these genes and those in the recipient species must be accounted for. The results of this study provide a scientific basis for some of the disappointing results that have historically obtained when using wild species as donors for crop improvement and provide a strategy for further successes.
