Light-load efficiency optimization for module integrated converters in photovoltaic systems

Efficient control strategies to optimize the light-load efficiency are necessary for module integrated converters (MICs) applied in photovoltaic (PV) systems. With no need for the additional current sensing, the MIC working in discontinuous conduction mode (DCM) automatically at light load can be achieved in this paper. Due to challenges in the efficiency optimization of the MIC and the trade-off between different losses in the MIC at light load, the maximum efficiency point tracking (MEPT) along with variable frequencies is proposed to further improve the light-load efficiency. With the proposed hybrid control strategies, the efficiency of a non-inverting Buck-Boost converter applied in PV systems can be greatly improved at light load. Furthermore, the proposed control strategies are analyzed in detail and verified with experimental results.
A Novel Probabilistic Method to Model the Uncertainty of Tidal Prediction

This paper develops a probabilistic model to predict the tidal current for modeling the prediction uncertainty, and thereby the forecast error. This requires the extension of the deterministic models from a point-by-point forecast to the probabilistic models with prediction intervals (PIs). The proposed model uses PIs to construct the bandwidth, which models the uncertainty of tidal current prediction properly. It uses the lower upper bound estimation method to train the neural network (NN) without making any assumption about the distribution of the forecast error. In order to adjust the weighting and biasing factors of NN, firefly algorithm with a new two-phase modification method is developed to search the problem space globally. Two benchmarks are used to show the search ability of the algorithm. The high accuracy of the proposed model is examined on the practical tidal data collected from the Bay of Fundy, NS, Canada.

Comparable aggregated indicators of QoS in the telecoms market Problem presented by

There are more than 500 alternative operators and 63 different KPIs that measure the quality of services. The Office of Electronic Communications (UKE) receives periodic reports for each operator with specific data which can be arranged in one table. This table has a lot of cells that are not filled and its structure may differ in time, which poses the problem of how to compare alternative operators and indicate eventual discrimination. Proposed was the concept of defining discrimination. This approach is based on some additional parameters, which were determined, however, they have not been collected so far.
Recombination and selection shape the molecular diversity pattern of nitrogen‐fixing Sinorhizobium sp. associated to Medicago

We investigate the genetic structure and molecular selection pattern of a sympatric population of Sinorhizobium meliloti and Sinorhizobium medicae. These bacteria fix nitrogen in association with plants of the genus Medicago. A set of 116 isolates were obtained from a soil sample, from root nodules of three groups of plants representing among‐species, within‐species and intraline diversity in the Medicago genus. Bacteria were characterized by sequencing at seven loci evenly distributed along the genome of both Sinorhizobium species, covering the chromosome and the two megaplasmids. We first test whether the diversity of host plants influence the bacterial diversity recovered. Using the same data set, we then analyse the selective pattern at each locus. There was no relationship between the diversity of Medicago plants that were used for sampling and the diversity of their symbionts. However, we found evidence of selection within each of the two main symbiotic regions, located on the two different megaplasmids. Purifying selection or a selective sweep was found to occur in the nod genomic region, which includes genes involved in nodulation specificity, whereas balancing selection was detected in the exo region, close to genes involved in exopolysaccharide production. Such pattern likely reflects the interaction between host plants and bacterial symbionts, with a possible conflict of interest between plants and cheater bacterial genotypes. Recombination appears to occur preferentially within and among loci located on megaplasmids, rather than within the chromosome. Thus, recombination may play an important role in resolving this conflict by allowing different selection patterns at different loci.
Calibration model of ultra-high-frequency partial discharge signals in HVDC converter transformers

This paper presents an approach for calibration of ultra-high-frequency (UHF) partial discharge (PD) signals in high voltage direct current (HVDC) transformer. A linear relationship between the amplitude of the UHF PD signal and PD apparent charge was obtained through the theoretical analysis. The finite-difference time-domain (FDTD) model of the simulated converter transformer showed that the UHF PD electromagnetic waves in converter transformer can propagate outside by the transformer bushing. The UHF PD signals propagated from the transformer bushing were obtained by the FDTD calculation. The simulation results showed that the amplitudes of the UHF PD signals were related to the transformer bushing and the detection position. Artificial cavity insulation model were designed to generate UHF PD signals, which were detected by a Peano fractal antenna in a series of experiments. The experimental results show that the antenna can detect the UHF PD signals inside of the transformer from the bushing and the PD apparent charge can be calibrated by the proposed approximate equations.
An online recommendation system for the taxi stand choice problem (Poster)

Nowadays, Informed Driving is crucial to the transportation industry. We present an online recommendation model to help the driver to decide about the best stand to head in each moment, minimizing the waiting time. Our approach uses time series forecasting techniques to predict the spatiotemporal distribution in real-time. Then, we combine this information with the live current network status to produce our output. Our online test-beds were carried out using data obtained from a fleet of 441 vehicles running in the city of Porto, Portugal. We demonstrate that our approach can be a major contribution to this industry: 395.361/506.873 of the services dispatched were correctly predicted. Our tests also highlighted that a fleet equipped with such framework surpassed a fleet that is not: they experienced an average waiting time to pick-up a passenger 5% lower than its competitor.
Exploring Implementation and Fidelity of Evidence-Based Behavioral Interventions for HIV Prevention: Lessons Learned From the Focus on Kids Diffusion Case Study

Evidence-based interventions (EBIs) are used in public health to prevent HIV infection among youth and other groups. EBIs include core elements, features that are thought to be responsible for the efficacy of interventions. The authors evaluate experiences of organizations that adopted an HIV-prevention EBI, Focus on Kids (FOK), and their fidelity to the intervention's eight core elements. A cross-sectional telephone survey was administered to 34 staff members from organizations that had previously implemented FOK. Questions assessed how the organization adhered to, adapted, dropped, or altered the intervention. None of the organizations implemented all eight core elements. This study underscores the importance for HIV intervention researchers to clearly identify and describe core elements. More effort is needed to reflect the constraints practitioners face in nonresearch settings. To ensure intervention effectiveness, additional research and technical assistance are needed to help organizations implement HIV prevention EBIs with fidelity.
Biosynthesis of exopolysaccharide by Pseudomonas aeruginosa

In batch cultures of Pseudomonas aeruginosa, the maximum rate of exopolysaccharide synthesis occurred during exponential growth. In nitrogen-limited continuous culture, the specific rate of exopolysaccharide synthesis increased from 0.27 g g of cell-1 h-1 at a dilution rate (D) of 0.05 h-1 to 0.44 g g of cells h-1 at D=0.1 H-1. The yield of exopolysaccharide on the basis of glucose used was in the range of 56 to 64%. Exopolysaccharide was also synthesized in carbon-limited cultures at 0.19 g g of cell-1 h-1 at D=0.05 h-1 in a 33% yield. Nonmucoid variants appeared after seven generations in continuous culture and rapidly increased in proportion to the total number of organisms present.
Virus-specific Activation of a Novel Interferon Regulatory Factor, IRF-5, Results in the Induction of Distinct Interferon α Genes*

Interferon regulatory factor (IRF) genes encode DNA-binding proteins that are involved in the innate immune response to infection. Two of these proteins, IRF-3 and IRF-7, serve as direct transducers of virus-mediated signaling and play critical roles in the induction of type I interferon genes. We have now shown that another factor, IRF-5, participates in the induction of interferon A (IFNA) and IFNB genes and can replace the requirement for IRF-7 in the induction of IFNA genes. We demonstrate that, despite the functional similarity, IRF-5 possesses unique characteristics and does not have a redundant role. Thus, 1) activation of IRF-5 by phosphorylation is virus-specific, and its in vivo association with the IFNA promoter can be detected only in cells infected with NDV, not Sendai virus, while both viruses activate IRF-3 and IRF-7, and 2) NDV infection of IRF-5-overexpressing cells preferentially induced the IFNA8 subtype, while IFNA1 was primarily induced in IRF-7 expressing cells. These data indicate that multiple signaling pathways induced by infection may be differentially recognized by members of the IRF family and modulate transcription of individual IFNA genes in a virus and cell type-specific manner.
Associations between tobacco marketing and use among urban youth in India.

OBJECTIVES To study if receptivity and exposure to tobacco marketing are correlated with tobacco use and psychosocial risk factors for tobacco use among a sample of urban Indian youth. METHODS Analysis of cross-sectional survey data from Project MYTRI, a group randomized intervention trial, in Delhi and Chennai, India, collected from sixth and eighth graders (n=11,642), in 32 schools in 2004. RESULTS Exposure to tobacco advertisements and receptivity to tobacco marketing were significantly related to increased tobacco use among students. CONCLUSION This association suggests the need to strengthen policy and program-based interventions in India to reduce the influence of such exposures.
Trends in geographical mortality differentials in India

This study examines the variation in mortality and mortality trends among different regions in India since the 1970s using data from the Sample Registration System (SRS). Evaluation of the SRS data quality confirms reliability for children and adults under the age of 60 years. Analysis of temporary life expectancy between the exact ages of 0 and 60 years shows that, after significant progress during the 1970s and 1980s, improvements in longevity slowed down in the 1990s and 2000s. The Gini coefficient and dispersion measure of mortality confirm the convergence of mortality across the regions in India between 1971–1975 and 2000–2004. In spite of this trend, a substantial difference between higher longevity in the south and lower longevity in the north was noteworthy in 2001–2004. Age decomposition of temporary life expectancy by age group 0–14 years and 15–59 years suggests that the steep longevity increase in the 1970s and 1980s was largely driven by a reduction in mortality in children under the age of 15 years. In the 1990s and early 2000s, the contribution of both young and adult age groups to longevity increase has diminished. India faces difficulties in making progress in further reductions of infant deaths to the minimum levels and also in fighting chronic and man-made diseases in individuals within older age groups.
Analysis and Minimization of Interaction in Decentralized Control Systems With Application to Roll-to-Roll Manufacturing

Analysis and minimization of interaction in multivariable systems employing decentralized controllers with application to roll-to-roll manufacturing systems are considered in this paper. A new interaction metric based on the Perron-Frobenius theory of nonnegative matrices is presented. This new metric may be used to quantify interaction in a large-scale interconnected system, establish constraints on closed-loop system stability, and provide a systematic design procedure for constructing decentralized pre-filters, which minimize interaction. The new interaction metric is applied to a roll-to-roll (R2R) manufacturing system, which utilizes decentralized control systems. R2R manufacturing is a continuous process in which flexible materials are transported on rollers through processing machinery where operations, such as printing, coating, lamination, etc., are performed to obtain finished products. Based on the Perron root interaction metric (PRIM), a comprehensive experimental study to analyze and minimize interaction on a large experimental R2R platform is presented. A representative sample of experimental results which demonstrate the applicability of PRIM is presented and discussed.
Fault-tolerant sorting using VLSI processor arrays

Parallel sorting is one of the most important computational problem. An efficient scheme for fault tolerant sorting is proposed, which is based on odd-even transposition sort with a linear array of processing elements (PEs). The faults in the array are tolerated as far as no more than a single compare-and-swap (CS) module fault exists in any three consecutive CS modules using the voting approach. The hardware overhead is basically an additional register and a voter per PE. The scheme can also be easily adapted to a two-dimensional processor arrays, using Shear sort. If the proposed approach is employed for only error detection, then multiple faults can be detected in each step of computation using only a simple XOR circuitry in each PE.
Efficient Attribute-Based Comparable Data Access Control

With the proliferation of mobile devices in recent years, there is a growing concern regarding secure data storage, secure computation, and fine-grained access control in data sharing for these resource-constrained devices in a cloud computing environment. In this work, we propose a new efficient framework named Constant-size Ciphertext Policy Comparative Attribute-Based Encryption (CCP-CABE) with the support of negative attributes and wildcards. It embeds the comparable attribute ranges of all the attributes into the user's key, and incorporates the attribute constraints of all the attributes into one piece of ciphertext during the encryption process to enforce flexible access control policies with various range relationships. Accordingly, CCP-CABE achieves the efficiency because it generates constant-size keys and ciphertext regardless of the number of involved attributes, and it also keeps the computation cost constant on lightweight mobile devices. We further discuss how to extend CCP-CABE to fit a scenario with multiple attribute domains, such that the decryption proceeds from the least privileged attribute domain to the most privileged one to help protect the privacy of the access policy. We provide security analysis and performance evaluation to demonstrate their efficiency at the end.
A new fully differential second generation current conveyor

The paper presents a new fully differential second generation current conveyor (FDCCII). In this circuit, the voltage relations between the differential input Y and the differential terminal X can be tuned by the extra bias current. The principle of the circuit is analyzed in detail. The simulation results show that the port characteristics of the proposed FDCCII are satisfied in the frequency range of 0~30 MHz.
Web data cleansing for information retrieval using key resource page selection

With the page explosion of WWW, how to cover more useful information with limited storage and computation resources becomes more and more important in web IR research. Using web page non-content feature analysis, we proposed a clustering-based method to select high quality pages from the whole page set. Although the result page set contains only 44.3% of the whole collection, it is related with more than 98% of links and covers about 90% of key information. Link property and retrieval affects are also observed and experiment results show that key resource selection method is more suitable for the job of data cleansing and the result page set outperforms the whole collection by smaller size and better retrieval performance.
Modeling and design of a humanoid robotic face based on an active drive points model

This study develops a face robot with human-like appearance for making facial expressions similar to a specific subject. First, an active drive points (ADPs) model is proposed for establishing a robotic face with less active degree of freedom for bipedal humanoid robots. Then, a robotic face design method is proposed, with the robot possessing similar facial appearance and expressions to that of a human subject. A similarity evaluation method is presented to evaluate the similarity of facial expressions between a robot and a specific human subject. Finally, the proposed facial model and the design methods are verified and implemented on a humanoid robot platform. Graphical Abstract
Acetylcholine receptor‐α subunit expression in myasthenia gravis: A role for the autoantigen in pathogenesis?

Previous studies have shown increased expression of acetylcholine receptor‐alpha (AChR‐α) subunit transcripts in myasthenia gravis (MG) and experimental MG (EAMG), but none examined the functional properties of this overexpression. In this study we examined the mRNA and protein expression of AChR‐α as well as the pattern of α‐bungarotoxin labeling in muscle tissue from EAMG mice with varying disease severity. AChR‐α expression was increased considerably in endplates from mice with severe EAMG, but it was distinct and greatly in excess of α‐bungarotoxin labeling. This “aberrant expression” occurred in mice with morphologic endplate damage, and the pattern of complement and immunoglobulin deposition in muscle from these mice appeared to mirror the pattern of AChR‐α expression. The loss of functional AChR in severe MG increases transcription of AChR‐α mRNA, but the expressed protein is “functionally inert,” failing to compensate for loss of AChR. This enhanced expression of AChR may play a role in driving the ongoing autoimmune response. Muscle Nerve 40: 279–286, 2009
Semantic Segmentation via Structured Patch Prediction, Context CRF and Guidance CRF

This paper describes a fast and accurate semantic image segmentation approach that encodes not only segmentation-specified features but also high-order context compatibilities and boundary guidance constraints. We introduce a structured patch prediction technique to make a trade-off between classification discriminability and boundary sensibility for features. Both label and feature contexts are embedded to ensure recognition accuracy and compatibility, while the complexity of the high order cliques is reduced by a distance-aware sampling and pooling strategy. The proposed joint model also employs a guidance CRF to further enhance the segmentation performance. The message passing step is augmented with the guided filtering which enables an efficient and joint training of the whole system in an end-to-end fashion. Our proposed joint model outperforms the state-of-art on Pascal VOC 2012 and Cityscapes, with mIoU(%) of 82.5 and 79.2 respectively. It also reaches a leading performance on ADE20K, which is the dataset of the scene parsing track in ILSVRC 2016. The code is available at https://github.com/FalongShen/SegModel.
Development and evaluation of a training program in peer support for former consumers.

While mental health policy in Australia promotes the involvement of mental health consumers in service planning, implementation and evaluation, little has been reported on the training required for the new roles that consumers are being expected to undertake. In this study, 10 former consumers of mental health services participated in a 16-week training program in peer support. The impact of the program on the psychological well-being of the participants was assessed using a battery of self-evaluation questionnaires and focus group interviews. Findings suggest that exposure to people with acute mental health problems (i.e. inpatients), did not, in this instance, adversely impact on the psychological well-being of the participants. Barriers to consumer participation in the mental health field are discussed and recommendations for the content and structure of future consumer peer support training initiatives are proposed.
