description: This paper reports a new approach to optimising the optical properties of solar cells and modules for
different geographical locations and environments from the perspective of system power output over a period of time.
Traditionally, the optical properties of solar cells have been optimised under the assumption of normal incident light
and the AM1.5G spectrum. However, depending on where a module is installed, this may not represent an accurate
optimisation strategy. With the proposed method, the wavelength-resolved angular-dependent absorption of a solar
cell or module and the detailed solar irradiance at specific times and locations are pre-calculated. These two
components can be combined to produce the light-induced current over a period of time at a particular location, and
used as a criterion by which the optical properties of a solar device can be optimised for that location. Simulations
were performed to demonstrate the capability of this method to estimate the system power output of a PV array and to
optimise the thickness of the anti-reflection coating for cells and modules installed at different geographical locations.
This method can predict the system power output accurately and be used to guide the development of customised PV
products for specific geographical locations or environments.

description: Bottom-up approaches allow the production of ultra-narrow and atomically precise graphene nanoribbons (GNRs), with electronic and optical properties controlled by the specific atomic structure. Combining Raman spectroscopy and ab-initio simulations, we show that GNR width, edge geometry and functional groups all influence their Raman spectra. The low-energy spectral region below 1000 cm-1 is particularly sensitive to edge morphology and functionalization, while the D peak dispersion can be used to uniquely fingerprint the presence of GNRs, and differentiates them from other sp2 carbon nanostructures.

description: This paper describes the results and experiences from a little over three years of operation of a solar park
with dual axis solar tracking in Piteå in Northern Sweden. The solar park has proven to be the best performing gridconnected
PV system in Sweden. The PV system was installed as a part of a research project called “Northsol”. The
goal with the project was to investigate if solar power plants can be technically and economically feasible at high
latitudes and in cold climates, and therefore the 20 kWp PV system comprises different commercial solar tracking- and
module technologies that can analyzed and compared.
The combination of low temperature, long-term ground coverage of snow and sunny weather give this installation
high potential for power production, but the location also give rise to a number of challenges related to cold climate.
The installation in Piteå was the first larger sized PV system in the region. In addition it is using the not so common
solar tracking technology which makes it even more unique.
During the years of operation the system has rendered a solid data basis for analyses which makes it possible to
make comparisons between different module- and tracker technologies evaluated from a cold climate point of view.
The full potential of an optimal designed solar park with tracking systems is here discussed based on the experience
gained from this project. The performance data from the system shows large differences between individual modules
and modules types. Currently the best performing modules outperforms the worst performing module by over 9 %. We
have also identified other areas which add on to the improvement potential of at least 4-5 %. This shows that there is
still room for significant improvements of the system performance.

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 2294-2299
description: For the assessment of the performance of this system, the available data base is comparatively sparse.
Especially on site measured irradiance data and power data are available in few timeslots only. In general only monthly
energy data from the system is available from June 2007 to March 2012 and the monitored energy within 30 minutes
from December 2013 to April 2014 and September to December 2014. Thus a first performance analysis was based on
the use of remotely sensed meteorological data (supplied by GeoModel and Automatic Weather Station). Result is that a
considerable under performance ratio of the system (compared PR modeled of 79% from AWS data versus PR actual
calculated of 73% from 30minutes power monitored and 71% for PR calculated from monthly energy output to 83% for
PR modeled within GeoModel data) has to be stated.
To get a better understanding of this under performance, the current work is focused on using both, the long-term offsite
meteorological data (in addition data from an automated weather located in Rutongo, 1.88o South and 30.05o East,
distance to the system at 4 km can be used) and the “spot-like” on site data to drive a simulation model for the system
performance. A model structured as described in [1] is used and parameterized according to nameplates data. From this, it
is tested whether an adapted simulation model (i.e. a variation of the parameter set for e.g. the rated Standard Test
Conditions power) can reflect the actual system performance. This is analyzed the correlation of the measured and
simulated monthly energy data and measured and simulated power data for the long term and short term data,
respectively. The validity of the adaption is tested by using subsets of the data for parameter identification and other
“unseen” subsets to prove that the respective model can be used to reflect the actual system performance.
The parameter adoptions necessary to achieve the improved correlation of simulation and measurement are discussed in
view of the deviations of the actual characteristics of the system components from their ex-factory status.

description: The frequency-dependent impedance is a fundamental property of electrical components. We show that it can be determined from the equilibrium dynamical fluctuations of the electrode charge in constant-potential molecular simulations, extending in particular a fluctuation-dissipation for the capacitance recovered in the low-frequency limit and provide an illustration on water/gold nanocapacitors. This work opens the way to the interpretation of electrochemical impedance measurements in terms of microscopic mechanisms, directly from the dynamics of the electrolyte, or indirectly via equivalent circuit models as in experiments.

description: In this paper, a methodology using a nonparametric model is used to forecast AC power output of PV plants using as inputs several forecasts of meteorological variables from a Numerical Weather Prediction (NWP) model and actual AC power measurements of PV plants. The methodology was built upon the R environment and uses Quantile Regression Forests as machine learning tool to forecast the AC power with a confidence interval. Real data from five PV plants was used to validate the methodology, and results show that the daily production of individual plants can be predicted with a skill score up to 0.361.

description: We provide an analysis of monitoring data of Photovoltaic systems in India for 2014. The data represents the
yield potential that should have been reached by the photovoltaic systems in the previous year. The results of the analysis
done on specific yield shows that more than 85% of all PV systems in India do not reach their technical potential due to
defects in the planning, construction and operating phases. We have used monthly yield data of PV systems to perform this
analysis. The data is filtered using a four-step algorithm to consider PV systems without any malfunction in this time period
and to improve the reliability of dataset to achieve quality results. The estimation of the yield shows the energy production of
photovoltaic systems in India, which could have been achieved by systems if the PV systems were planned, built and
operated in a proficient manner. The results are objectively verified and do not have subjective influence. The analysis
shows that for relatively small number of evaluable PV systems, the statistical analysis can be done and that the results
obtained can be reliable to replicate real operational status of a Photovoltaic system.
title:  Focused on Freedom: Exploring the Potential of Grading Contracts to Support Writers in the Secondary English Language Arts Classroom
Creators: name: Fluharty, Margaret McGregor
Publisher: name: Old Dominion University Libraries
Year: 2023

description: Drawing on qualitative methods, I engaged in a practitioner inquiry (Cochran-Smith & Lytle, 2009) to investigate the use of contract grading to promote educational freedom (hooks, 2009; Love, 2020) in the post-secondary writing classroom. In addition, I explored the potential of this practice in the secondary English language arts setting.

To better understand the perspectives of both post-secondary writing instructors and secondary English teachers on the use of grading contracts, I conducted focus groups and engaged in artifact analysis (Billups, 2019). Results showed that post-secondary instructors who utilized grading contracts in their classroom saw changes primarily in their students’ engagement and communication compared to what they experienced when engaging in traditional grading practices. While secondary teachers appreciated the transparency that grading contracts promoted, they believed that any changes to their current grading practices would not deter their students from seeking motivation from grades, but rather would leave them feeling uneasy in their attempts to navigate a new system. Using the data derived from these results, I provided commentary on the necessity of professional learning within this conversation, as well as a discussion of future research that is necessary to better understand the potential of ungrading in the secondary English language arts class.

description: In the probe limit, we investigate holographic paramagnetism-ferromagnetism phase transition in the four-dimensional (4D) and five-dimensional(5D) Lifshitz black holes by means of numerical and semi-analytical methods, which is realized by introducing a massive 2-form field coupled to the Maxwell field. We find that the Lifshitz dynamical exponent $z$ contributes evidently to magnetic moment and hysteresis loop of single magnetic domain quantitatively not qualitatively. Concretely, in the case without external magnetic field, the spontaneous magnetization and ferromagnetic phase transition happen when the temperature gets low enough, and the critical exponent for the magnetic moment is always $1/2$, which is in agreement with the result from mean field theory. And the increasing $z$ enhances the phase transition and increases the DC resistivity which behaves as the colossal magnetic resistance effect in some materials. Furthermore, in the presence of the external magnetic field, the magnetic susceptibility satisfies the Cure-Weiss law with a general $z$. But the increase of $z$ will result in shortening the period of the external magnetic field.

description: This paper presents preliminary results of the “proper.ma” project consisting on the first theoretical maps
and their calculation method before any calibration. We have calculated photovoltaic DC yields using a “simple model”
which is detailed in this paper. Before drawing any map, the “simple model” photovoltaic DC yields are compared to two
other calculation tools (PVSyst software and PiViDyn software), both of them set to use the same input meteorological
data (taken from “PVSyst” software since this does not accept external data). At the end of this comparison, it has been
decided that the “simple model” results will have to be “corrected” with PiViDyn software results because of its precision
due to its hourly resolution level. Plots of the PiViDyn software yields against the “simple model” ones have shown that a
parabolic correlation fits better the data than a linear one. Finally, photovoltaic DC yields maps, as calculated using the
“corrected simple model”, are compared to Solar Med Atlas data.
For the maps, 1192 appropriate representative points have been selected in throughout all Morocco and we have
calculated the photovoltaic monthly and yearly DC yields for these points with the “corrected simple model”.

description: Motivated by the ATLAS and CMS announcements of the excesses of di-photon events, we discuss the production and decay processes of di-photon resonance at future $e^+e^-$ colliders. We assume that the excess of the di-photon events at the LHC is explained by a scalar resonance decaying into a pair of photons. In such a case, the scalar interacts with standard model gauge bosons and, consequently, the production of such a scalar is possible at the $e^+e^-$ colliders. We study the production of the scalar resonance via the associated production with photon or $Z$, as well as via the vector-boson fusion, and calculate the cross sections of these processes. We also study the backgrounds, and discuss the detectability of the signals of scalar production with various decay processes of the scalar resonance. We also consider the case where the scalar resonance has an invisible decay mode, and study how the invisible decay can be observed at the $e^+e^-$ colliders.

description: Dedicated surveys searching for Fast Radio Bursts (FRBs) are subject to selection effects which bias the observed population of events. Software injection systems are one method of correcting for these biases by injecting a mock population of synthetic FRBs directly into the realtime search pipeline. The injected population may then be used to map intrinsic burst properties onto an expected signal-to-noise ratio (SNR), so long as telescope characteristics such as the beam model and calibration factors are properly accounted for. This paper presents an injection system developed for the Canadian Hydrogen Intensity Mapping Experiment Fast Radio Burst project (CHIME/FRB). The system was tested to ensure high detection efficiency, and the pulse calibration method was verified. Using an injection population of ~85,000 synthetic FRBs, we found that the correlation between fluence and SNR for injected FRBs was consistent with that of CHIME/FRB detections in the first CHIME/FRB catalog. We also noted that the sensitivity of the telescope varied strongly as a function of the broadened burst width, but not as a function of the dispersion measure. We conclude that some of the machine-learning based Radio Frequency Interference (RFI) mitigation methods used by CHIME/FRB can be re-trained using injection data to increase sensitivity to wide events, and that planned upgrades to the presented injection system will allow for determining a more accurate CHIME/FRB selection function in the near future.

description: Species in Alternaria sections Infectoriae and Pseudoalternaria are commonly isolated from agricultural crops and a variety of other plant hosts. With the increasing appreciation that species from these two sections are often the dominant taxa recovered from important cereal crops, the need for improved understanding of their biodiversity and taxonomy has grown. Given that morphological characteristics and existing molecular markers are not sufficient for distinguishing among species, we expanded the genomic resources for these sections to support research in biosystematics and species diagnostics. Whole genome assemblies for 22 strains were generated, including the first genomes from section Infectoriae or Pseudoalternaria strains sampled from Canada, which significantly increases the number of publicly released genomes, particularly for section Pseudoalternaria. We performed comprehensive phylogenomic analyses of all available genomes (n = 39) and present the first robust phylogeny for these taxa. The segregation of the two sections was strongly supported by genomewide data, and multiple lineages were detected within each section. We then provide an overview of the biosystematics of these groups by analyzing two standard molecular markers from the largest sample of section Infectoriae and Pseudoalternaria strains studied to date. The patterns of relative diversity suggest that, in many cases, multiple species described based on minor morphological differences may actually represent different strains of the same species. A list of candidate loci for development into new informative molecular markers, which are diagnostic for sections and lineages, was created from analyses of phylogenetic signals from individual genes across the entire genome.

description: We use single-cycle THz fields and the femtosecond magneto-optical Kerr effect to respectively excite and probe the magnetization dynamics in two thin-film ferromagnets with different lattice structure: crystalline Fe and amorphous CoFeB. We observe Landau-Lifshitz-torque magnetization dynamics of comparable magnitude in both systems, but only the amorphous sample shows ultrafast demagnetization caused by the spin-lattice depolarization of the THz-induced ultrafast spin current. Quantitative modelling shows that such spin-lattice scattering events occur on similar time scales than the conventional spin conserving electronic scattering ($\sim30$ fs). This is significantly faster that optical laser-induced demagnetization. THz conductivity measurements point towards the influence of lattice disorder in amorphous CoFeB as the driving force for enhanced spin-lattice scattering.

description: Detailed analysis of 5000 systems that took part in the 2014 measurement campaign “Counting the
Sun” was performed as besides the weekly yield also system descriptions were available. With average energy yield
of 33.4 kWh/kWp, and average performance ratio of 0.74 for all systems, performance ratio was found to be
dependent on the ratio of inverter DC nominal power and system DC rated power. For low cost inverters, this ratio
was 1.16, while for high cost inverters it was 0.95. Apparently, expected better performance does not warrant higher
capacity inverter, in the case of high cost inverters. However, due to the 1-week period, performance ratio was found
not to be dependent on this ratio. Also, different components (modules, inverters) do not conclusively influence
performance ratios. A longer monitoring period is expected to lower variation of these values such that statistically
relevant differences can be observed.

However, it is not yet clear how many such events future surveys will detect nor how to optimally find them. We use the known properties of FRBs to forecast detection rates of gravitational lensing on delay timescales from microseconds to years, corresponding to lens masses spanning fifteen orders of magnitude. We highlight the role of the FRB redshift distribution on our ability to observe gravitational lensing. We consider cosmological lensing of FRBs by stars in foreground galaxies and show that strong stellar lensing will dominate on microsecond timescales. Upcoming surveys such as DSA-2000 and CHORD will constrain the fraction of dark matter in compact objects (e.g. primordial black holes) and may detect millilensing events from intermediate mass black holes (IMBHs) or small dark matter halos. Coherent all-sky monitors will be able to detect longer-duration lensing events from massive galaxies, in addition to short time-scale lensing. Finally, we propose a new application of FRB gravitational lensing that will measure directly the circumgalactic medium of intervening galaxies.

description: The web-based program package has been developed for modeling of the amount of the solar energy
falling on the panel of solar car along the road. The input parameters of the model are: 1) instant of Greenwich time
2) geographical coordinates (latitude, longitude and height from the sea level to the point at road); 3) the road tilt. The
main output of the model is the amount of solar energy falling on the solar car for any instant of time and position of the
car on road. As a study case the road Kiel-Berlin(Germany) and Baku-Shemakha (Azerbaijan) are taken. The database of
solar energy, obtained by the calculations on the model for those roads has been used to develop the easy-to-use interface
JavaScript based front-end web-application to simulate the motion of the solar car. The web application of this model
can be considered as the prototype of the navigation system of solar cars which will provide their optimal controlling.

description: Protocols to ensure that messages are delivered in causal order are a ubiquitous building block of distributed systems. For instance, distributed data storage systems can use causally ordered message delivery to ensure causal consistency, and CRDTs can rely on the existence of an underlying causally-ordered messaging layer to simplify their implementation. A causal delivery protocol ensures that when a message is delivered to a process, any causally preceding messages sent to the same process have already been delivered to it. While causal delivery protocols are widely used, verification of their correctness is less common, much less machine-checked proofs about executable implementations. We implemented a standard causal broadcast protocol in Haskell and used the Liquid Haskell solver-aided verification system to express and mechanically prove that messages will never be delivered to a process in an order that violates causality. We express this property using refinement types and prove that it holds of our implementation, taking advantage of Liquid Haskell's underlying SMT solver to automate parts of the proof and using its manual theorem-proving features for the rest. We then put our verified causal broadcast implementation to work as the foundation of a distributed key-value store.

description: Semiconducting half- and, to a lesser extent, full-Heusler compounds are promising thermoelectric materials due to their compelling electronic properties with large power factors. However, intrinsically high thermal conductivity resulting in a limited thermoelectric efficiency has so far impeded their widespread use in practical applications. Here, we report the computational discovery of a class of hitherto unknown stable semiconducting full-Heusler compounds with ten valence electrons ($X_2YZ$, $X$=Ca, Sr, and Ba; $Y$= Au and Hg; $Z$=Sn, Pb, As, Sb, and Bi) through high-throughput $ab-initio$ screening. These new compounds exhibit ultralow lattice thermal conductivity $κ_{\text{L}}$ close to the theoretical minimum due to strong anharmonic rattling of the heavy noble metals, while preserving high power factors, thus resulting in excellent phonon-glass electron-crystal materials.

Aging by near-extinctions in many-variable interacting populations

description: Models of many-species ecosystems, such as the Lotka-Volterra and replicator equations, suggest that these systems generically exhibit near-extinction processes, where population sizes go very close to zero for some time before rebounding, accompanied by a slowdown of the dynamics (aging). Here, we investigate the connection between near-extinction and aging by introducing an exactly solvable many-variable model, where the time derivative of each population size vanishes both at zero and some finite maximal size. We show that aging emerges generically when random interactions are taken between populations. Population sizes remain exponentially close (in time) to the absorbing values for extended periods of time, with rapid transitions between these two values. The mechanism for aging is different from the one at play in usual glassy systems: at long times, the system evolves in the vicinity of unstable fixed points rather than marginal ones.

description: Monitoring data of grid-connected photovoltaic installations provides a valuable source to follow the
operation and performance of a PV facility. Main failure modes can be spotted from the analysis of only this data.
Combining measured monitoring data with detailed simulation results however, provides additional information that
can reveal more subtle problems or help to track down the source of a complex malfunction. In this paper we describe
how such a comparison can be performed, that would allow the detection of different kinds of problems on the module,
string and inverter level.
After some general considerations on how to compare measured data to simulation results, including the corresponding
uncertainties, we study how possible discrepancies can point to problems either with the monitoring, the operation or
the simulation results. The level of detail in the monitoring data will determine how well this assignment can be done
in an unambiguous way.
A tool allowing this kind of analysis is currently being implemented in the PVsyst software and its capabilities to
compare monitoring data to the simulation results are being expanded.

description: We have used realistic local interactions based on the recent update of the strangeness $-2$ Nijmegen ESC08c potential to calculate the bound state problem of the $ΞNN$ system in the $(I)J^P=(\frac{1}{2})\frac{3}{2}^+$ state. We found that this system presents a deeply bound state lying $13.5$ MeV below the $Ξd$ threshold. Since in lowest order, pure S$-$wave configuration, this system can not decay into the open $ΛΛN$ channel, its decay width is expected to be very small. We have also recalculated the $(I)J^P=(\frac{3}{2})\frac{1}{2}^+$ state and we have compared with results of quark-model based potentials.

description: Short-term variability is one of the critical challenges to greater penetration of PV into the electricity
system. New grid-codes [1], [2] require combining the PV generator with some form of energy storage technology in
order to reduce short-term PV power fluctuation. Herein, it is compared through different merit indexes the strategies
available in the literature to comply with the maximum allowable ramp-rate limitation imposed by a grid code. This work
presents a guide whose aim is to facilitate the election of implementing one control strategy or another and the storage
technology to be used. All the strategies have been evaluated over 1-year 5 second power measurements which were
recorded at the output of 500 kW inverters at the 38.5 MW Amareleja (Portugal) PV plant for a maximum allowable
ramp-rate value of 2%/min.
