description: Information about the current, past and future global irradiation is crucial to plan, maintain and survey solar plants and energy grids as well as for energy trading and technologies in the area of building automation or building energy management. Till summer 2020 the European and African continent as well as India and parts of central Asia have been covered by the MSG and IODC satellites. By summer 2020 the satellite data products of Meteotest reached a seamless coverage of the entire continental land mass between 60° N and 60° S. This is achieved by extending the satellite mosaic with additional data from the two satellites GOES-16 (USA) and Himawari 8 (Japan) and will result in a global data archive as well as a real time data service providing high quality irradiation data for most of the areas with relevant solar energy potential. As part of the go-live of the global satellite coverage in the first half of 2020 we will present results from a benchmark by comparing the satellite data derived with the HelioMont method against ground measurements from regional and global radiation networks (e.g. BSRN or SURFRAD).

description: We compare the performance of Machine Learning (ML) and Numerical Weather Prediction (NWP) models for solar forecasting at 60-min steps-ahead intervals up to 72 horizons (3-days ahead), and then seek to improve the accuracy of the better performing model by combining the two models. We develop the ML forecasting model using the gradient boosting regression tree algorithm (boostTree) with Global Horizontal Irradiance (GHI) time series data for 2019 collected in Doha (Qatar). We then evaluate this ML model and the NWP model for the same year and location using the relative Root Mean Square Error (rRMSE). We conclude by developing a boostTree classifier that uses as training material the results of the evaluation of the ML and NWP models to predict the best performing forecasting model for each choice of input time series. Our results show that on average the ML model forecasts GHI with nearly an 8% lower error rate than NWP model, across the 72 one-hour steps-ahead intervals – 18.2% vs. 26% rRMSE for the ML and NWP models, respectively. On average, the combined ML-NWP model rivals the accuracy of the ML model showing a reduction in error rate (rRMSE) of up to 1.5%. We find that ML models show accurate results for day(s)-ahead forecasts, and their performance can be improved through combination with NWP models.

description: Forecasting energy production is the key to the optimization of renewable energy systems. In the underlying project, forecasting methods were developed and the evaluation of the forecasting methods was carried out using statistical methods as well as simulation studies allowing the assessment of the economic value of these forecasts. This paper focuses on the use and benefit of PV-power forecasts in general as well as the results of the studies on the forecasting methods developed within this project. It was found out that in Austria the so-called local players appear as the most relevant potential beneficiaries of a short-term forecast, because they are directly affected and can conduct short-term optimization. In addition, balancing groups will have a need of improved PV forecasts in the near future, as the standard load profile will be replaced by smart metering. Simulation studies on specific applications showed that the economic efficiency of an optimized control for a PV-battery system with forecasts is low, whereas the application of forecasts in the control of a hybrid PV-diesel system possesses a surprisingly high economic potential.

description: Continuous increase of the production of photovoltaic energy requires precise forecasting to ensure grid stability and allow use cases such as auto-consumption. This paper aims to perform a detailed evaluation of an intraday forecasting algorithm based on the combination of two machine learning algorithms: a Gradient Boosting Tree (GBT) and a Multivariate Adaptive Regression Spline (MARS). The analysis will be carried out using the Mean Absolute Error (MAE) and the daily Normalized Mean Absolute Error (daily NMAE) on a full year data from a 63 kWp PV plant located in the south of France and for time horizons ranging from 1 to 6 hours. In order to perform a detailed analysis, the data will be categorizing based on weather conditions using a daily clear-sky index.

description: Renewable power generation based on solar energy is increasing. However, since solar energy is greatly dependent on weather conditions and causes uncertainty of power generation, there are difficulties and limitations in efficient and effective energy management of it. This paper proposes a solar irradiance prediction model based on meteorological radiation models (MRMs) to estimate accurate hourly solar irradiance. The proposed model uses general input parameters easily obtained from weather data and excludes rare parameters used by complex MRMs. In a direct normal irradiance, aerosol and water-vapor transmittances greatly affect prediction accuracy. In a diffuse horizontal irradiance, aerosol transmittance dominantly affects prediction accuracy. We evaluate the performance of the proposed model based on hourly weather data and measured irradiances during one year. The cross-correlation coefficient is 0.963 on clear and cloudy skies; and it is 0.998 on only clear sky. The proposed model outperforms previous simple methods and shows similar performance compared to a complex MRM. It is expected to enhance prediction accuracy of solar power generation based on hourly forecast weather data.

description: A non-trivial slope $r$ on a knot $K$ in $S^3$ is called a characterizing slope if whenever the result of $r$-surgery on a knot $K'$ is orientation preservingly homeomorphic to the result of $r$-surgery on $K$, then $K'$ is isotopic to $K$. Ni and Zhang ask: for any hyperbolic knot $K$, is a slope $r = p/q$ with $|p| + |q|$ sufficiently large a characterizing slope? In this article we answer this question in the negative by demonstrating that there is a hyperbolic knot $K$ in $S^3$ which has infinitely many non-characterizing slopes. As the simplest known example, the hyperbolic knot $8_6$ has no integral characterizing slopes.

Assessment on the Humanitarian Logistics Performances of IRC-Ethiopia using Balanced Scorecard (The Case of Somali Region, Jigjiga Humanitarian Response Program)
Creators: name: Chekol, Yenehun
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: In order to alleviate the suffering of people, effective and efficient performance of humanitarian organization is important. The balanced scorecard has enabled many organizations to overcome the deficiencies traditional performance assessments that largely focused on financial performance of an organization. This system provides feedback on internal business processes and external outcomes to continually improve organizational performance and results. The clearest benefit of Balanced Scorecard (BSC) approach in the humanitarian logistics performance of humanitarian organization is the importance it places on customer service. In the humanitarian sector, the customer's perception of service and the media's portrayal of this service greatly affect an organization's reputation and potential donations, so the customer perspective is critical in this sector. The purpose of this study was to investigate the performance of humanitarian organizations in Jigjiga and identify the main challenges of the organization that hindered to achieve its intended objectives by the application of the BSC taking IRC as a case organization. It assessed the logistics performances of IRC and ways of improving the logistics performances of the organization in enhancing the beneficiaries' satisfaction in Somali Region, Jigjiga humanitarian response program in four woredas namely; Erer, Shinile, Ayishia, and Dambel in the Siti Zone. Data was collected using a questionnaire from 100 community respondents and 35 IRC staff informants. The data was analyzed using percentages and descriptive statistics such as the mean. The findings were presented in tables and figures. The study findings revealed that the customer perspective as a component of BSC is effective in measuring performance of humanitarian organizations. The customer perspective captures measures regarding IRC operations and processes necessary to meet customers' expectations and increase their satisfaction. There research identified also different challenges on the performance of IRC to reach to its beneficiaries effectively. These include presence of well-defined and functional procurement procedures, Flexibility to revise and improve internal business processes, Corruption, poor governance and Proper control mechanisms over purchases mainly challenged the performance of the organization.

description: We provide an updated report on a field trial of a new meteorological station concept for resource assessment at the site of a prospective utility-scale photovoltaic (PV) power plant to be developed by 7X Energy. Cost savings are achieved by substituting Atonometrics PV reference cells for thermopile pyranometers in a unique multi-reference-cell array configuration that allows accurate determination of global horizontal irradiance (GHI) and by using advanced remote diagnostics to minimize the need for on-site visits for sensor cleaning. Reference data are also obtained from a second station at the site employing thermopile pyranometers and maintained through weekly site visits for pyranometer cleaning. Data from both stations are compared to industry-leading SolarAnywhere® satellite-derived irradiance measurements from Clean Power Research and are used for tuning of the satellite model for long-term irradiance prediction and site resource assessment. Results comparing the new station concept employing PV reference cells versus the traditional one based on thermopile pyranometers showed that both compared equivalently with the satellite data and tuning model within instrument uncertainties, although small bias deviations likely due to calibration differences require more investigation.

description: Responding to calls from the National Science Foundation (NSF) for new proposals to measure the gravitational constant $G$, we offer an interesting experiment in deep space employing the classic gravity train mechanism. Our setup requires three bodies: a larger layered solid sphere with a cylindrical hole through its center, a much smaller retroreflector which will undergo harmonic motion within the hole and a host spacecraft with laser ranging capabilities to measure round trip light-times to the retroreflector but ultimately separated a significant distance away from the sphere-retroreflector apparatus. Measurements of the period of oscillation of the retroreflector in terms of host spacecraft clock time using existing technology could give determinations of $G$ nearly three orders of magnitude more accurate than current measurements here on Earth. However, significant engineering advances in the release mechanism of the apparatus from the host spacecraft will likely be necessary. Issues with regard to the stability of the system are briefly addressed.

description: A modeling-based simulation tool with a graphical user interface (GUI) was developed to predict PV performance of bifacial systems. The model was validated by comparing it with performance data measured from East/West vertical bifacial arrays in different locations. The main outdoor test system is at the Turku University of Applied Sciences (TUAS) in Turku Finland (Lat. 60.44 N, Long. 22.29 E). The aim is to predict the energy yield from this system configuration in northern latitudes. The benefits from E-W vertical bifacial systems have been well documented and include higher energy yields, better load matching, reduction in soiling and snow covering, just to mention a few. Our study focuses on the accuracy of the model to reproduce collected data at the site, by using different sources of meteorological data.

description: We study localized plasmonic excitations in bilayer graphene (BLG) nanodisks, comparing AA-stacked and AB-stacked BLG and contrasting the results to the case of two monolayers without electronic hybridization. The electrodynamic response of the BLG electron gas is described in terms of a spatially homogeneous surface conductivity, and an efficient alternative two-dimensional electrostatic approach is employed to carry out all the numerical calculations of plasmon resonances. Due to a unique electronic band structures, the resonance frequency of the traditional dipolar plasmonic mode in the AA-stacked BLG nanodisk is roughly doping independent in the low-doping regime, while the mode is highly damped as the Fermi level approaches the interlayer hopping energy $γ$ associated with tunneling of electrons between the two layers. In addition to the traditional dipolar mode, we find that the AB-stacked BLG nanodisk also hosts a new plasmonic mode with energy larger than $γ$. This mode can be tuned by either the doping level or structural size, and furthermore, this mode can dominate the plasmonic response for realistic structural conditions.

description: Considering the rapid and dynamic growth of international trade and market competitiveness in our world, the Ethiopian government introduces and implements fiscal and non fiscal scheme to promote and encourage export trade. The aim of this research paper is the impact of export trade incentive on export growth of Ethiopia from 2003-2018. In this study using explanatory research method combined with trend analysis and time series analysis, we presented finding, results and conclusion by using secondary data which were collected from main actors from government institutions like Ethiopian Revenue and Customs Authority (ERCA), National Bank of Ethiopia (NBE), Ministry of finance and economic development (MOFED), Development Bank of Ethiopia(DBE). Based on the time series statistical regression analysis , the study found that fiscal incentives(voucher scheme) and financial incentives(Export credit guarantee) and REER are statistical significant with export growth where as the other independent variables Duty drawback and Manufacturing bonded warehouse were statistically insignificant for export growth. The study also suggests that care should be taken to improve the implementation of incentives and formulation of incentive policies. Otherwise Without these improvements the incentive schemes cannot achieve their expected levels of effectiveness.

description: The solar forecast research continues to increase in the academic and industry world to provide tools and methodologies with increasingly performances. The levels of penetration of this renewable energy source is growing and optimized tools are needed in order manage the electrical grid in a proper and safe way. With the new electricity market designs reaching shorter gate closers, the importance of forecast tools for solar energy is of significance importance. One of the methodologies that are being study in the literature is the use of satellite pictures. The satellite pictures provide a wide area monitoring of an electricity asset due to their top-down wide range nature. In the case of renewable solar energy, it can assist the decision-making in the continuous market, which occurs in an hourly basis. In this paper, it is presented a forecast methodology based on satellite pictures, which computes a cloud index. Using theoretical solar radiation of clear sky and the cloud index, the solar power forecast is calculated. The cloud index is calculated using a clear sky library, built using satellite pictures and solar PV aggregation metering data from the region under study. This library defines the probability density distribution that characterizes the clear sky for each hour. Thus, the cloud index is calculated by comparing the probability density distribution of the new picture with the clear sky library.

description: Many steps in a solar energy project — resource assessment, design, yield prediction, operation and maintenance — depend on accurate and reliable solar irradiance measurements. However, different types of sensors are used and have multiple applications, depending on their measurement. We have considered the main two types of sensors: thermal irradiance sensors (pyranometers) and silicon reference cells. In this study, first we present the differences in measurement results of the two sensors. This is accomplished by evaluating the global irradiance in the plane of array (POA) measured from both sensors installed in different photovoltaic systems (PV systems) around Germany. From this assessment, we enumerate the main factors that contribute to their differences: temperature dependence, angular response, spectral response and calibration deviation. Furthermore, a set of correction equations is applied to the silicon reference cell’s data. These equations correlate the two sensors and the factors that contribute to their deviation (obtained from the data analysis, previous studies and the sensor’s technical specifications). Finally, we evaluate the correction model with a new set of data, achieving a reduction of the differences between sensors (Root Mean Square Deviation RMSD) of around 38%.

description: The generally accepted view that spin polarization is induced by the asymmetry of the global crystal space group has limited the search for spintronics [1] materials to non-centrosymmetric materials. Recently it has been suggested that spin polarization originates fundamentally from local atomic site asymmetries [2], and therefore centrosymmetric materials may exhibit previously overlooked spin polarizations. Here by using spin- and angle-resolved photoemission spectroscopy (spin-ARPES), we report helical spin texture induced by local Rashba effect (R-2) in centrosymmetric monolayer PtSe$_2$ film. First-principles calculations and effective analytical model support the spin-layer locking picture: in contrast to the spin splitting in conventional Rashba effect (R-1), the opposite spin polarizations induced by R-2 are degenerate in energy while spatially separated in the top and bottom Se layers. These results not only enrich our understanding of spin polarization physics, but also may find applications in electrically tunable spintronics.

description: In this paper, the performance of a direct current (DC) distribution system is modelled and compared for a single-family residential building with a conventional alternating current (AC) system to quantify the potential energy savings and gains in PV utilization. The modelling is also made for two different climates to quantify the impact of the geographical location. Results show that the system losses are reduced by 19-46% and the PV utilization increased by 3.9-7.4% when using a DC distribution system compared to an AC equivalent, resulting in system efficiency gains in the range of 1.3-8.8%. Furthermore, it is shown that the geographical location has some effect on the system's performance and PV utilization, but most importantly the grid interaction is paramount for the performance of the DC topology.

description: We investigate the minimum planet mass that produces observable signatures in infrared scattered light and submm continuum images and demonstrate how these images can be used to measure planet masses to within a factor of about two. To this end we perform multi-fluid gas and dust simulations of discs containing low mass planets, generating simulated observations at $1.65 μ$m, $10 μ$m and $850 μ$m. We show that the minimum planet mass that produces a detectable signature is $\sim 15 M_\oplus$: this value is strongly dependent on disc temperature and changes slightly with wavelength (favouring the submm). We also confirm previous results that there is a minimum planet mass of $\sim 20 M_\oplus$ that produces a pressure maximum in the disc: only planets above this threshold mass generate a dust trap that can eventually create a hole in the submm dust. Below this mass, planets produce annular enhancements in dust outward of the planet and a reduction in the vicinity of the planet. These features are in steady state and can be understood in terms of variations in the dust radial velocity, imposed by the perturbed gas pressure radial profile, analogous to a traffic jam. We also show how planet masses can be derived from structure in scattered light and sub-mm images. We emphasise that simulations with dust need to be run over thousands of planetary orbits so as to allow the gas profile to achieve a steady state and caution against the estimation of planet masses using gas only simulations.

description: Different companies may adopt different supply chain management practices to enable them achieve the objectives if their supply chain. This becomes necessary due to the fact that the modern business environment puts managers in demanding situations where they have to balance between the demands of consumers and the company's desire for growth and enhanced profitability. Most of the managers have therefore realized that for them to efficiently and effectively manage such a situation, they must focus on supply chain management from a strategic perspective. Companies all over the world are pursuing supply chain as the latest methodology to reduce costs, increase customer satisfaction, better utilize assets, and build new revenues. To conduct this study the research has five objectives these are To study the existing practices of supply chain management from the five SCM practices perspectives ,To investigate and get insight about the level of integration and coordination of the case company with its suppliers and customers, To investigate and measure the perceived performance of the supply chain flexibility and adaptability and to get better insight in the case company, To identify factors affecting implementation of supply chain strategies at Faffa Food Share Company and To identify measures to be taken to improve supply chain management at Faffa Food Share Company. For the accomplishment of this, the study was employed through descriptive design in which the selections of the respondents were carried out by using judgmental, purposive and convenience sampling techniques.

description: Materials science is a highly active research area, covering a broad range of topics. Many communities exist which focus on specific aspects; despite their differences, all of them acknowledge the need of establishing good data management practices following the FAIR principles (Findability, Accessibility, Interoperability, Reusability). This presentation highlights the results achieved so far in this area by three research projects: the NFFA (Nanoscience Foundries and Fine Analysis)-Europe Pilot, the German Joint Lab MDMC (integrated Model and Data-driven Materials Characterization), and the German consortium NFDI-MatWerk (National Research Data Infrastructure for Materials Science and Engineering). The commonalities among them, particularly in terms of requirements, tools and infrastructure solutions are showcased. These success stories underscore the crucial importance of aligning data management activities across multiple communities, in order to enable interdisciplinary collaborations and facilitate efficient data sharing and reuse.

description: This work aims to maximize the photovoltaic solar electricity’s self-consumption, through the development and validation of an equivalent electric model of a vanadium redox flow battery and its implementation in an energy management strategy. The first phase of the work presents the modelling of the 5.0 kW/60 kWh VRFB integrated in a solar photovoltaic microgrid - 3.5 kWp monocrystalline plus 3.2 kWp polycrystalline technology - at the University of Évora. The model is based in the equivalent electric circuit model built upon the consulted bibliographic references allowing to calculate the battery parameters on the desired power. It considers the auxiliary power consumption and operational parameters and despite its simplicity attains for a good match with experimental results. Upon its validation, the model is further enhanced as to better describe the VRFB real response in its regular operating conditions. Assessment of the enhanced model is based on key performance indicators such as selfconsumption rate, rate of battery usage or electric grid independence. In this work an approach to best fit the battery modelling and simultaneously the energy management strategy for a PV+VRFB system is presented, based on actual operating conditions and on a prescribed EMS goal.
title: Individual differences in emotional disposition, psychological factors, and central mechanisms in the development and maintenance of persistent pain

description: Pain is a complex multifaceted experience. Pathology does not always correlate to symptomatology,
with many individual differences being involved in the genesis of chronic pain. Identifying some of 
the factors associated with pain will help to build a model for vulnerability and inform on targeted 
interventions.
Study one compared a large chronic pain population to a healthy population for differences in 
psychosocial factors in the workplace. The results indicated that, compared to healthy individuals,
people in pain reported significantly poorer relationships with their managers and colleagues, felt 
they were discriminated against, felt subjected to more threats and abuse, and were not as
appreciated for their efforts. Interestingly, they felt more competent in their job role and reported
greater job security.
Study two assessed whether attending to a painful stimulus (intrinsic attention to pain) was 
associated with a ‘pro-nociceptive’ phenotype (characterised by enhanced temporal summation and 
less efficient conditioned pain modulation). The results showed that endogenous pain modulatory 
mechanisms were responsible for 39% of the variation in intrinsic attention to pain. 
Study three correlated Five-Factor Mindfulness Questionnaire (FFMQ) scores with rates of 
sensitisation to a repetitive/consistent pain stimulus over a brief paradigm. The findings revealed 
that people who scored low on the FFMQ were at higher risk of sensitisation to pain.
Study four examined the construct validity of the Central Sensitisation Inventory (CSI) by meta-analysing correlations of the CSI with measures of nociceptive responsivity (Quantitative Sensory 
Testing) and psychological constructs (anxiety, depression, stress etc). The CSI was strongly 
correlated with psychological constructs and showed weak/no association to nociception. 
Overall, this thesis suggests that a wide range of biopsychosocial factors contribute towards pain. 
Workplace environment, endogenous modulatory mechanisms, trait mindfulness and psychopathology should be considered when building a model to help predict vulnerability and
inform on targeted intervention, to improve resilience to pain.

description: This paper presents a method to evaluate if the optimization of sizing and operation of wind + photovoltaic solar power plants, together with battery-based storage systems, could increase the dispatchability of these energy sources in utility-scale hybrid power plants. For this purpose, a case study with real data from an operating wind farm and an R&D photovoltaic solar plant both installed at the same site in the municipality of Brotas de Macaúbas in the Brazilian Northeast state of Bahia were used to demonstrate the proposed evaluation method. The results showed that in the case study there is a relevant complementarity between wind and solar generation output, with an average annual Pearson Correlation Coefficient of -0.51. The 40% wind and 60% solar hybrid plant was the optimal combination to meet the load. With this combination, the required storage capacity for the temporal matching between hybrid plant generation and load demands was 6% of the generated energy. The results also showed that it is possible to reduce the use of transmission systems due to the temporal complementarity of wind and solar sources, and that storage systems can help in the optimization of transmission infrastructure sizing.
28 Years of Operational Data for a Utility Scale 103 kWp PV Plant (1989-2017) Analysis of Degradation of PV Modules, Inverters and System Performance with Technical and Economical Comparison to the Repowered 260 kWp PV Plant (2017-2019)

description: The PV plant on the noise barrier of the highway A13 at the time of its construction 1989 was the largest PV plant in Switzerland (104 kWp) and the first PV noise barrier plant worldwide, providing 28 years of field data for analysis. Degradation of PV modules, inverter efficiency and system performance are analyzed. A technological and economical comparison with the 260 kWp PV plant after repowering 2017 is performed. Flasher measurements at STC of the 1989 PV modules after 28 years of operation show degradation of nominal power from 15…37%, corresponding to 0.55…1.32% per year. Inverter efficiency after 12 years of operation is 1.12% lower at 91.61%. Yield decrease started 2007, but was partially compensated by increasing solar irradiation. Analysis of performance ratio shows a linear decrease from 2006 to 2016. Performance decrease is far higher than can be explained with PV module and inverter efficiency degradation. It is therefore to large parts due to degradation in Balance of System (BoS) components such as array boxes, DC wiring, fuses, et. al. The repowered PV plant produces almost 3 times the energy of the original PV plant on the same length of noise barrier while system prices have dropped 95.1% from 1989 to 2017.

description: The electrical energy generated by solar photovoltaic (PV) contributes significantly to the transition to green energy production. A comprehensive analysis of PV systems' yield data and performance is necessary to plan future energy production by solar photovoltaics. This publication evaluates publicly available yield data, configuration, and location of 32,744 rooftop PV systems in Europe. The analyzed period ranges from 2012 to 2019 and has a time resolution of one day. The considered PV systems are installed in the Netherlands, Belgium, Luxembourg, Germany, France, and Italy. The evaluation focuses on the long-term specific yield and performance ratio analysis. The specific yield over the whole area shows the expected south-north gradient. The long-term average specific yields and performance ratio of systems that ran continuously from 2015 to 2019 were 947 kWh/kWp and 0.73 in the Netherlands, 959 kWh/kWp and 0.73 in Belgium, 979 kWh/kWp and 0.73 in Luxembourg, 990 kWh/kWp and 0.74 in Germany, 1102 kWh/kWp and 0.73 in France, and 1195 kWh/kWp and 0.73 in Italy. The average performance ratio of PV systems operated for five consecutive years from 2015 to 2019 shows no correlation with system capacity. The performance trend of PV systems installed after 2008 does not increase.
