description: The validity of a closure called the minimal tau approximation (MTA), is tested in the context of dynamo theory, wherein triple correlations are assumed to provide relaxation of the turbulent electromotive force. Under MTA, the alpha effect in mean field dynamo theory becomes proportional to a relaxation time scale multiplied by the difference between kinetic and current helicities. It is shown that the value of the relaxation time is positive and, in units of the turnover time at the forcing wavenumber, it is of the order of unity. It is quenched by the magnetic field -- roughly independently of the magnetic Reynolds number. However, this independence becomes uncertain at large magnetic Reynolds number. Kinetic and current helicities are shown to be dominated by large scale properties of the flow.

description: Excerpt from the report Summary: Iraq is primarily an agricultural country with a considerable number of people engaged in pastoral activity. However, petroleum dominates its export trade, and light industry is increasing in growing urban centers. About three-fifths of Iraq's agricultural output by value comes from crops and two-fifths from livestock products. The country is an exporter of livestock products, fruit, cotton, and in some years, barley, but an importer of several other agricultural products, especially sugar, tea, fats and oils, and, in recent years, grain. Grains are by far the most important crops in Iraq. They occupy over 80 percent of the area reported in crops and account for well over half the calories in the average diet. Livestock products are next in importance to the diet, generally contributing about 20 percent of the calories. Livestock are raised throughout the country and are an important, or the only, source of income for a large share of the population of Iraq. Barley is the leading winter crop, while rice and cotton are the main summer crops. Much citrus and other fruits are grown for local consumption while Iraq is one of the world's leading producers of dates; and, in turn, dates are usually the first or second most important agricultural export, competing with barley for first place. Other important exports are wool, hides and skins, and cotton.

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1563-1568
description: This study investigates how thermal signatures observed in PV systems using infrared thermography (IRT) affect the performance of PV modules and strings. To assess this, we use IRT images as a basis for circuit modeling of modules with defected solar cells. This allows us to calculate the performance of the individual modules with thermal signatures and the module string. We model the IV characteristics of defective modules based on IRT images and fit the results to field IV traces of the imaged modules. By IRT imaging, several thermal signatures have been identified, and by using a portable IV tracer, the power loss related to each defect under the given conditions has been found. Information from the IRT images are used as input to a model we have developed for defect evaluation, and a comparison of model and IV tracer data for a range of defective solar modules is presented. The string modeling shows that the power loss from a given thermal signature is highly dependent on string length and circuit design. For string sizes larger than 20 modules, only defects that affect two or more module substrings are expected to give a power loss higher than 3%.

description: In the Einstein-Cartan theory of torsion-free gravity coupling to massless fermions, the four-fermion interaction is induced and its strength is a function of the gravitational and gauge couplings, as well as the Immirzi parameter. We study the dynamics of the four-fermion interaction to determine whether effective bilinear terms of massive fermion fields are generated. Calculating one-particle-irreducible two-point functions of fermion fields, we identify three different phases and two critical points for phase transitions characterized by the strength of four-fermion interaction: (1) chiral symmetric phase for massive fermions in strong coupling regime; (2) chiral symmetric broken phase for massive fermions in intermediate coupling regime; (3) chiral symmetric phase for massless fermions in weak coupling regime. We discuss the scaling-invariant region for an effective theory of massive fermions coupled to torsion-free gravity in the {\it low-energy limit}.

description: Aerial Infrared Thermography (IRT) is a non-destructive and cost-effective method for detecting faults in large-scale photovoltaic (PV) power plants. However, the visual assessment of the images captured by aerial IRT, and the analysis of a large number of image frames is very time-consuming. This paper proposes a method for detecting and classifying faults on PV modules, through aerial IRT images, combining Digital Image Processing (DIP) and Convolutional Neural Networks (CNNs) algorithms. With the results obtained so far, the IR images acquired were successfully processed with DIP techniques to detect the faults of PV modules in the power plant that are used as samples for training the CNN. The developed neural network algorithm can detect faults on the aIRT images and classify them in three categories: disconnected substrings, hot spots, and disconnected strings. The results have demonstrated that the method is effective in detecting and classifying faults, and it is an important step for the full automation of aIRT inspection.

description: Psychological distress is a prominent concern for South Asian individuals in the United States. Despite substantial research indicating that the model minority myth has numerous consequences with varying implications—including mental health implications—for Asian Americans, very little is known about its impact for South Asians. The present study used an embedded mixed-methods design to explore the relationship between internalization of the model minority myth and psychological distress for South Asians in the United States. Results indicated that South Asians experience mental health consequences of the myth in complex and dichotomous ways: they balance feelings of both pride and pressure related to being a model minority, as well as experiences of both privilege and marginalization in society. Findings also elucidated meaningful differences in experience between South Asian diasporic subgroups, highlighting the importance of considering multiple marginalization and other systemic factors in assessing the impact of the model minority myth.

description: The so-called supersymmetric flavour and CP problems are deeply related to the origin of flavour and hence to the origin of the SM Yukawa couplings themselves. We show that realistic SU(3) flavour symmetries with spontaneous CP violation reproducing correctly the SM Yukawa matrices can simultaneously solve both problems without ad hoc modifications of the SUSY model. We analyze the leptonic electric dipole moments and lepton flavour violation processes in these models. We show that the electron EDM and the decay mu -> e gamma are naturally within reach of the proposed experiments if the sfermion masses are measurable at the LHC.

description: The renovation challenge leads to the need for novel approaches to conceive buildings and their energy supply. Buildings are more than just stand-alone units taking energy from the grid. They are becoming increasingly active elements of the energy network by consuming, producing, storing and supplying energy, thus transforming the EU energy market and shifting from centralised, fossil-fuel based national systems towards a decentralised, renewable, interconnected and variable system. To address these challenges a European consortium of 17 partners has been brought together to develop the EnergyMatching project “Adaptable and adaptive RES envelope solutions to maximize energy harvesting and optimize EU building and district load matching”. Funded under the Horizon 2020 programme, EnergyMatching is developing new concepts and technologies to optimize the interaction between buildings and energy systems for the best match between decentralised RES-based energy production and building load profiles, as well as to simplify the energy demand management for the energy distributors. The solutions will be tested in real conditions in 3 pilot demonstrators with different geographical and climatic conditions.

description: We study the phenomenon of grain-boundary premelting for temperatures below the melting point in the phase-field crystal model of a pure material with hexagonal ordering in two dimensions. We investigate the structures of symmetric tilt boundaries as a function of misorientation for two different inclinations and compute in the grand canonical ensemble the disjoining potential V(w) that governs the fundamental interaction between crystal-melt interfaces as a function of the premelted layer width w. The results reveal qualitatively different behaviors for high-angle grain boundaries that are uniformly wetted, with w diverging logarithmically as the melting point is approached from below, and low-angle boundaries that are punctuated by liquid pools surrounding dislocations, separated by solid bridges. This qualitative difference between high and low angle boundaries is reflected in the w-dependence of the disjoining potential that is purely repulsive (V'(w)<0 for all w) above a critical misorientation, but switches from repulsive at small w to attractive at large w for low angles. In the latter case, V(w) has a minimum that corresponds to a premelted boundary of finite width at the melting point. Furthermore, we find that the standard wetting condition (the grain boundary energy is equal to twice the solid-liquid free energy) gives a much too low estimate of the critical misorientation when a low-temperature value of the grain boundary energy is used. In contrast, a reasonable estimate is obtained if the grain boundary energy is extrapolated to the melting point, taking into account both the elastic softening of the material at high temperature and local melting around dislocations.

description: Excerpts from the report Summary: Agricultural activities are limited by the country's predominantly mountainous topography which limits the development of farmland. Only about one-fourth of the land is used for crop production. The remainder is mainly used as rangeland for migratory flocks of sheep and goats. Of the cultivated area, more than one-half is terraced land developed along the mountain slopes. Crop production falls into 2 general categories--dryland crops and irrigated crops. Generally, the dryland crops are grains and pulses while the high-valued fruits and vegetables are grown with supplemental irrigation. The production of fruits and vegetables for export has proven to be a profitable enterprise in Lebanon. During the 1950's the area devoted to fruits and vegetables was rapidly expanded, especially that planted to citrus fruits, bananas, and apples. Lebanon is a net importer of agricultural commodities. Grains and live animals for meat are the principal imports although substantial quantities of other foods are also imported. Cotton, wool, and hides and skins are among the nonfood agricultural imports, some of which are reexported. Agricultural exports are generally about one-half the value of agricultural imports. Citrus fruits and apples are the principal agricultural exports, although vegetables, wool, tobacco, and bananas also rank high.

description: Early-career teacher stress, burnout and attrition are growing problems in the United States. The current study focused on the impact of social desirability on positive and negative constructs (i.e. positive-negative affect, coping-perceived stress reactivity) in a group of student-teachers beginning their teaching internships. Additionally, this research also proposed a new definition of social desirability, as an adaptive motivation to social evaluation, based on the patterns of relationships between social desirability and the aforementioned constructs. These definitions were assessed a sample of 61 student-teachers from the University of Maryland’s teacher preparation program who were completing their senior year internship. As many forms of research rely on self-reports, social desirability’s role as a validity confound has been widely documented, however, its relationship to individual well-being has not been investigated as widely. The bias perspective of social desirability was not consistent with the results of this study.

Characterisation & Simulation of Si Cells

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 251-254
description: Minimizing the resistivity of carrier-selective contacts (c) is crucial to achieve high-efficiency solar cells. In the case of silicon hetero-junction (SHJ) solar cells, a combination of thin-film silicon layers enables selective carrier collection by engineering the Fermi energy. However, this electrode structure also inherently yields potential barriers for carrier collection, which leads to resistive losses. Here, we present a rigorous modelling approach based on numerical simulations using Sentaurus TCAD. After demonstrating that our platform is capable of reasonably predicting experimentally-retrieved c values, we explain the transport phenomena involved for a wide range of contactstack combinations and their impact on the external parameters of interdigitated solar cells. We provide practical insights on how to minimize the contact resistivity in terms of the properties of the transparent conductive oxide and doped silicon thin film layers and thus increase the conversion efficiency of SHJ solar cells.

Concentrators and PV for Space Applications

description: 36th European Photovoltaic Solar Energy Conference and Exhibition; 1546-1548
description: Solar concentrated photovoltaic and thermal (CPVT) hybrid systems are attractive due to the generation both electric and thermal energies and having increased efficiency of the system. The efficiency of solar cells of CPVT systems is affected by operation temperature and solar radiation concentration rate. To analyse the efficiency of solar cells the simple mathematical model for different type concentrating solar cells is proposed. This approach is based on a linear approximation of experimentally obtained data and assumption on the superposition of operation temperature and concentration influences on efficiency. By proposed mathematical model the efficiencies of the single junction and multi-junction solar cells are determined. The results match reasonably with simulation and experimental data obtained by other authors. The proposed mathematical model can be used for determination of solar cells efficiency of CPVT hybrid and CPV non-hybrid systems.
Randomized distributed computing on rings
Creators: name: Higham, Lisa
Publisher: name: University of British Columbia
Year: 2010

description: The communication complexity of fundamental problems in distributed computing on an asynchronous ring are examined from both the algorithmic and lower bound perspective. A detailed study is made of the effect on complexity of a number of assumptions about the algorithms. Randomization is shown to influence both the computability and complexity of several problems. Communication complexity is also shown to exhibit varying degrees of sensitivity to additional parameters including admissibility of error, kind of error, knowledge of ring size, termination requirements, and the existence of identifiers. A unified collection of formal models of distributed computation on asynchronous rings is developed which captures the essential characteristics of a spectrum of distributed algorithms those that are error free (deterministic, Las Vegas, and nondeterministic), and those that err with small probability (Monte Carlo and nondeterministic/probabilistic). The nondeterministic and nondeterministic/probabilistic models are introduced as natural generalizations of the Las Vegas and Monte Carlo models respectively, and prove useful in deriving lower bounds. The unification helps to clarify the essential differences between the progressively more general notions of a distributed algorithm. In addition, the models reveal the sensitivity of various problems to the parameters listed above. Complexity bounds derived using these models typically vary depending on the type of algorithm being investigated. The lower bounds are complemented by algorithms with matching complexity while frequently the lower bounds hold on even more powerful models than those required by the algorithms. Among the algorithms and lower bounds presented are two specific results which stand out because of their relative significance. 1. If g is any nonconstant cyclic function of n variables, then any nondeterministic algorithm for computing g on an anonymous ring of size n has complexity [Formula Omitted] bits of communication; and, there is a is nonconstant cyclic boolean function [Formula Omitted], such that [Formula Omitted] can be computed by a Las Vegas algorithm in [Formula Omitted] expected bits of communication on a ring of size n. 2. The expected complexity of computing AND (and a number of other natural functions) on a ring of fixed size n in the Monte Carlo model is [Formula Omitted] messages and bits where [Formula Omitted] is the allowable probability of error.
Inner disk regions revealed by infrared interferometry

description: I review the results obtained by long-baseline interferometry at infrared wavelengths on the innermost regions around young stars. These observations directly probe the location of the dust and gas in the disks. The characteristic sizes of these regions found are larger than previously thought. These results have motivated in part a new class of models of the inner disk structure. However the precise understanding of the origin of these low visibilities is still in debate. Mid-infrared observations have probed disk emission over a larger range of scales revealing mineralogy gradients in the disk. Recent spectrally resolved observations allow the dust and gas to be studied separately. The few results shows that the Brackett gamma emission can find its origin either in a wind or in a magnetosphere but there are no definitive answers yet. In a certain number of cases, the very high spatial resolution seems to reveal very close companions. In any case, these results provide crucial information on the structure and physical properties of disks surrounding young stars especially as initial conditions for planet formation.

description: For advanced automated operational monitoring of Photovoltaic (PV) systems, e.g. in order to distinguish losses due to self-shading from malfunctions, direct and diffuse irradiance at the module plane (plane of array, POA) are required separately. However, in practice, usually only measured values of global POA irradiance (GPOA) are recorded on site. There is thus a need for a model to divide GPOA into its direct (IPOA) and diffuse components (DPOA). This paper compares and evaluates two models recently developed that perform such separation. The aim of this work is to show the advantages and disadvantages that these two models offer and how they differ from each other. In order to compare and evaluate them, two different POA data sets were used. The first data set is generated using SolarGIS satellite-based data for 16 different locations across Germany. The second data set contains on-site measured DPOA and GPOA data from a PV power plant located in south-west Germany. Results from both models show good matching with satellite-based data from the 16 different locations.

description: The objective of this study is to improve the hour ahead solar irradiance forecasts in the inter tropical zone using ensembles of forecasts from several models in French Guiana. The first model of the ensemble is a physical model: Weather Research and Forecasting model (WRF), the second and third model are statistical: the persistence and Auto Regression. The fourth model is and hybrid physical statistical model. It is obtained by post processing WRF output with a Kalman filter bias correction method. We use a Ridge Regression method to linearly combine all the forecasts with weights varying by models. We validated our method over three months of GHI measurements with hourly data of global horizontal irradiance (GHI) from six stations of the French national weather service. We used the MAE, MBE and RMSE and clear sky index to compute the statistics. For all sky conditions and stations merged, we found that statistical and hybrid statistical models perform better than WRF under low variability sky conditions. For highly variable sky conditions WRF outperform other models. For all sky conditions merged, WRF Kalman has the lowest RMSE and MAE, respectively 29% and 22%. We also found that aggregating the ensemble members using a Ridge regression method decreases RMSE and MAE of the most accurate single model by approximately 5%.

description: The consequences of police contact for youth have been established in the prior literature (e.g., Kirk & Sampson, 2013), yet the potential for guilt by association after police contact has not been thoroughly explored. The current study examines how a youth’s police contact may increase the likelihood of a friend’s police contact after controlling for behavior and other characteristics that are associated with justice system involvement. This study expands upon labeling theory and the concept of “stickiness” by testing whether guilt by association could act as a status characteristic that is “sticky” in two ways. Using longitudinal data from a sample of rural youth, I find that a friend’s police contact is associated with an increase in the likelihood of one’s own contact after accounting for other predictors of police contact. Thus, this study provides additional evidence that police contact may be harmful for youth and their social network.

description: One of the prerequisites for a reliable energy yield prediction of bifacial PV systems is the capability of modeling the back side irradiance of those systems with high accuracy. Currently, the most important optical models used to quantify the reflected irradiance on the backside of a bifacial solar panel are view factor and ray tracing. The MoBiDiG simulation tool [1] [2] has been developed at ISC Konstanz uses the quasi 3D view factor (VF) concept to model the rear irradiance. In addition to the VF concept, ray tracing (RT) has been adopted to determine the back side irradiance of bifacial modules by using the open source tool bifacial radiance that has been developed by the National Renewable Energy Laboratory (NREL) [3]. A customized solar panel has been built in order to evaluate the accuracy of the existing optical models by locally resolved rear irradiance measurement. The performance of rear irradiance has been investigated along the rows of the customized PV module during sunny and cloudy days. The comparison of measured and modeled data has been carried out on hourly, daily and monthly basis, the results show lower deviations for solar cells located in the center of the PV module than on the edge. Moreover, the concept of decisive solar cells has been introduced and applied to both measured and modeled data, solar cells located in the center rows were found to act as most decisive solar cells. Finally, considering the installation configuration studied here i.e bifacial mounting with low clearance height (below 0.2m) both hourly ray tracing and quasi 3D view factor approaches are able to model long term cumulative irradiance seen by solar cells with a very high accuracy ranging from +/-0.5% to +/-2%.

The same construction leads to scalar Fourier transformations on the affine group, simplifying and extending the Fourier transformation proposed by Kirillov.

Fast Density Codes for Image Data

Subjects: subject: Neural and Evolutionary Computing (cs.NE)

description: Recently, a new method for encoding data sets in the form of "Density Codes" was proposed in the literature (Courrieu, 2006). This method allows to compare sets of points belonging to every multidimensional space, and to build shape spaces invariant to a wide variety of affine and non-affine transformations. However, this general method does not take advantage of the special properties of image data, resulting in a quite slow encoding process that makes this tool practically unusable for processing large image databases with conventional computers. This paper proposes a very simple variant of the density code method that directly works on the image function, which is thousands times faster than the original Parzen window based method, without loss of its useful properties.

description: PVSITES project has developed an ambitious set of BIPV solutions specially tailored to provide a comprehensive and robust answer to market demands. One of these solutions is a low concentration PV solution with associated passive climate control properties for building integration in façades and skylights. Glass-glass semitransparent PV modules in conjunction with integrated optical elements are proposed to concentrate solar radiation onto the cells during the central part of the year and allow light passing towards the interior of the building during the winter. At the central part of the year, the lenses deviate solar radiation onto the cells with a double effect: (1) an increase in PV production in comparison with a traditional PV system of same installed power and (2) a reduction in cooling demands due to an enhanced solar control, with less radiation entering the building during the summer. The savings provided by the system are obviously greatly enhanced in locations with high direct irradiation conditions. The system is being demonstrated in three experimental outdoor set-ups with different climates: two experimental test benches in ACCIONA facilities (Seville, Spain), Field Lab Testing facility at Tecnalia site (Derio, Spain) and FACT building at CEA-INES (Chambéry, France).

description: High-order harmonic generation from atomic systems is considered in the crossed fields of a relativistically strong infrared laser and a weak attosecond-pulse train of soft x-rays. Due to one-photon ionization by the x-ray pulse, the ionized electron obtains a starting momentum that compensates the relativistic drift which is induced by the laser magnetic field, and allows the electron to efficiently emit harmonic radiation upon recombination with the atomic core in the relativistic regime. In this way, short pulses of coherent hard x-rays of up to 40 keV energy and 10 as duration can be brought about.

description: The hippocampus has been implicated in the pathophysiology of depression. This study examined whether youth hippocampal subregion volumes were differentially associated with maternal depression history and youth’s depressive symptoms across the transition to adolescence. 74 preadolescent offspring (Mage=10.74+/-.84 years) of mothers with (n=33) and without a lifetime depression history (n=41) completed a structural brain scan. Youth depressive symptoms were assessed prior to the neuroimaging assessment at age 9 (Mage=9.08+/-.29 years), at the neuroimaging assessment, and in early adolescence (Mage=12.56+/-.40 years). Maternal depression was associated with preadolescent offspring’s reduced bilateral hippocampal head volumes and increased left hippocampal body volume. Reduced bilateral head volumes were associated with offspring’s increased concurrent depressive symptoms. Furthermore, reduced right hippocampal head volume mediated associations between maternal depression and increases in offspring depressive symptoms from age 9 to age 12. Findings implicate reductions in hippocampal head volume in the intergenerational transmission of risk from parents to offspring.

description: Schizochytrium meal protein (SMP) extracted from Schizochytrium meal was hydrolyzed by flavourzyme. Response surface methodology (RSM) was used to optimize the extraction conditions for the protein extraction yield from Schizochytrium meal. 1,1-Diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity (DRSA) was used to evaluate the antioxidant activity of hydrolysates. The orthogonal test was used to investigate the effects of three independent variables, namely protease dosage, hydrolysis time, and pH. The optimum conditions obtained were as follows: protease dosage of 7%, hydrolysis time of 1.5 h, pH of 6, under which, DRSA at the concentration of 2 mg/mL was 89.38%. Aspartic and glutamic acid constituted approximately 26.32% of the total amino acids, and glutamic acid was the most abundant amino acid of Schizochytrium meal protein hydrolysate (SMPH) by amino acid composition analysis, which may have contributed to the scavenging activity of SMPH. Moreover, SMPH was made into chewable tablets with suitable formula and high humidity stability. These findings indicate that Schizochytrium meal can be reused as a raw material for preparation of antioxidant peptides.

description: Masculinity is a highly-valued but elusive status in society. This is due to its socially conferred nature. While masculinity is associated with good traits, it is also associated with negative traits such as aggression against others. Negative masculine traits occur when males lose masculine status and seek to reestablish it. While research has identified contexts that elicit masculinity loss, research to date has not focused on the role leaders play in shaping followers’ interpretations of such contexts. The present study sought to address this by examining the effect of supportive versus abusive leadership on followers’ experience of masculinity in potentially threatening contexts. Dahl, Vesio & Weaver’s (2015) research method for threatening masculinity was expanded upon to test this. Results revealed significant differences in public discomfort and anger between supportive and abusive leadership. Leadership also impacted followers’ hostility towards women through changes in masculinity loss stress. Surprisingly, Dahl et al.’s (2015) method for threatening masculinity could not be replicated. Potential explanations, as well as theoretical and empirical implications are discussed.

description: In this work, we present the set up of a testing facility for photovoltaic (PV) modules and other PV system components in Dakar, Senegal. This creation is the result of a collaboration between the Polytechnic Schools of Dakar (ESP) and Lausanne (EPFL) aiming at improving the quality of PV systems by selecting components with sufficient quality. This testing center should also contribute to the education of all actors involved in the PV sector and contribute to research activities on the aging and failure mode analysis of PV modules exposed to sub-Saharian climates such as the hot semiarid climate of Dakar region but also those of the Economic Community of West African States (ECOWAS) region, including Senegal.

description: We present the results of daily monitoring of 6.7 GHz methanol maser in Cepheus A (Cep A) using Yamaguchi 32-m radio telescope as well as the results of imaging observations conducted with the JVN (Japanese VLBI Network). We indentified five spectral features, which are grouped into red-shifted (-1.9 and -2.7 km/s) and blue-shifted (-3.8, -4.2, and -4.9 km/s), and we detected rapid variabilities of these maser features within a monitoring period of 81 days. The red-shifted features decreased in flux density to 50% of its initial value, while the flux density of the blue-shifted features rapidly increased within a 30 days. The time variation of these maser features showed two remarkable properties; synchronization and anti-correlation between the red-shifted and the blue-shifted. The spatial distribution of the maser spots obtained by the JVN observation showed an arclike structure with a scale of $\sim$1400 AU, and separations of the five maser features were found to be larger than 100 AU. The absolute position of the methanol maser was also obtained based on the phase-referencing observations, and the arclike structure were found to be associated with the Cep A-HW2 object, with the elongation of the arclike structure nearly perpendicularly to the radio continuum jet from the Cep A-HW2 object. These properties of the masers, namely, the synchronization of flux variation, and the spectral and spatial isolation of features, suggest that the collisional excitation by shock wave from a common exciting source is unlikely. Instead, the synchronized time variation of the masers can be explained if all the maser features are excited by infrared radiation from dust which is heated by a common exciting source with a rapid variability.
