description: In order to evaluate the performances of bifacial PV modules, 3 HJT high efficiency bifacial modules
and 9 monofacial, from different producer, have been installed in a standard test facility for modules evaluation. The
modules were fully indoor characterized (measurement of Pm, temperature and irradiance coefficients). The on-field
electrical parameters of the modules and the irradiance of the front and back sides of the modules were measured with
high accuracy equipment for 6 months from June to December 2014.
The contribution of the back face radiation was 8.5% of the front face radiation. The gain in performance ratio for
bifacial modules was from 4.7% to 13.7% (considering all the technologies) and average 10% considering monofacial
modules of the same technology.
With respect to the effect of the position of the sun, as expected the bifacial always outperformed the monofacial: the
gain is proportional to the sun elevation (reflection of the beam component) and take advantage of the reflection of
the diffuse component when the beam component is lower (early and later hours of the day).
We also show that for the same inverter size, bifacial modules produce slightly more energy, as they take more
advantage of the diffuse component of radiation and of the direct reflections when the sun is low on the horizon.

description: In this paper we would demonstrate how we developed a model to determine cell-to-module
performance starting from available literature. After fabricating 60-cell modules with 2 different types of cells and 2
different stringing configurations, measurements of these modules then allowed us to validate the developed model.
In an attempt to demonstrate potential applications for this model, we then show how potential improvements can be
quantified and pinpoint which losses are affected. This way, we indicate a potential for improving the fabricated
MWT modules with an increase in absolute efficiency up to ~1.7% for the module. On top of that we demonstrate
that an additional increase of ~0.1% in absolute efficiency can be obtained by dividing the cells, e.g. into half or third
cells.

description: Optical diffraction tomography (ODT) is an interferometric microscopy technique capable of measuring 3-D refractive index (RI) distribution of transparent samples. Multiple 2-D holograms of a sample illuminated with various angles are measured, from which 3-D RI map of the sample is reconstructed via the diffraction theory. ODT has been proved as a powerful tool for the study of biological cells, due to its non-invasiveness, label-free and quantitative imaging capability. Recently, our group has demonstrated that a digital micromirror device (DMD) can be exploited for fast and precise control of illumination beams for ODT. In this work, we systematically study the precision and stability of the ODT system equipped with a DMD and present measurements of 3-D and 4-D RI maps of various types of live cells including human red blood cells, white blood cells, hepatocytes, and HeLa cells. Furthermore, we also demonstrate the effective visualization of 3-D RI maps of live cells utilizing the measured information about the values and gradient of RI tomograms.

description: We report an experimental demonstration of a local amplification of the spin Hall voltage using an expanding depletion zone at a pn-junction in GaAs/AlGaAs Hall-bar microdevices. It is demonstrated that the depletion zone can be spatially expanded by applying reverse bias by at least 10~$μ$m at low temperature. In the depleted regime, the spin Hall signals reached more than one order of magnitude higher values than in the normal regime at the same electrical current flowing through the micro-device. It is shown that the pn-bias has two distinct effects on the detected spin Hall signal. It controls the local drift field at the Hall cross which is highly non-linear in the pn-bias due to the shift of the depletion front. Simultaneously, it produces a change in the spin-transport parameters due to the non-linear change in the carrier density at the Hall cross with the pn-bias.

description: Some effective field theories exhibit dynamical resonances that, when properly included, mitigate their bad behaviour at high energies. Unitarization of the partial wave amplitudes is the preferred method to unveil such resonances. Interpreting the Einstein-Hilbert theory in the spirit of effective Lagrangians, we implement the Inverse Amplitude Method and unitarize the one-loop level graviton-graviton scattering in pure gravity. Due to the presence of infrared divergences, the analysis requires a careful treatment of the infrared region and the introduction of infrared regulators, carefully selected in order to fulfil perturbative unitarity. No evidence of any graviball is found, in contradiction with a recent study.

description: The doctrine of Integral Action presented by the National Army that supplements ground operations, has the ability to articulate the capabilities of the institution to unified actions, i.e., the integration of activities of governmental and non-governmental institutions and support the fulfillment of the mission in the national territory. Thus, it is how the department of Integral Action responds to the importance that the Army has given to the activities of support to the development and mitigation of social instability factors in operations in recent years, especially after the signing of the peace agreement. However, despite of the social impact that this department has within the Army, some of the activities remain unknown by the community, generating ignorance of the social work carried out by the institution. For this reason, it is necessary to highlight the activities carried out through the Integral Action Department, which has facilitated the approach to a social listening, strengthening the institutional framework in the regions that are victims of the armed conflict in Colombia.

description: In this paper, a novel approach for joint power control and user scheduling is proposed for optimizing energy efficiency (EE), in terms of bits per unit energy, in ultra dense small cell networks (UDNs). Due to severe coupling in interference, this problem is formulated as a dynamic stochastic game (DSG) between small cell base stations (SBSs). This game enables to capture the dynamics of both the queues and channel states of the system. To solve this game, assuming a large homogeneous UDN deployment, the problem is cast as a mean-field game (MFG) in which the MFG equilibrium is analyzed with the aid of low-complexity tractable partial differential equations. Exploiting the stochastic nature of the problem, user scheduling is formulated as a stochastic optimization problem and solved using the drift plus penalty (DPP) approach in the framework of Lyapunov optimization. Remarkably, it is shown that by weaving notions from Lyapunov optimization and mean-field theory, the proposed solution yields an equilibrium control policy per SBS which maximizes the network utility while ensuring users' quality-of-service. Simulation results show that the proposed approach achieves up to 70.7% gains in EE and 99.5% reductions in the network's outage probabilities compared to a baseline model which focuses on improving EE while attempting to satisfy the users' instantaneous quality-of-service requirements.

description: Our concern is the problem of determining the data complexity of answering an ontology-mediated query (OMQ) formulated in linear temporal logic LTL over (Z,<) and deciding whether it is rewritable to an FO(<)-query, possibly with some extra predicates. First, we observe that, in line with the circuit complexity and FO-definability of regular languages, OMQ answering in AC^0, ACC^0 and NC^1 coincides with FO(<,\equiv)-rewritability using unary predicates x \equiv 0 (mod n), FO(<,MOD)-rewritability, and FO(RPR)-rewritability using relational primitive recursion, respectively. We prove that, similarly to known PSPACE-completeness of recognising FO(<)-definability of regular languages, deciding FO(<,\equiv)- and FO(<,MOD)-definability is also \PSPACE-complete (unless ACC^0 = NC^1). We then use this result to show that deciding FO(<)-, FO(<,\equiv)- and FO(<,MOD)-rewritability of LTL OMQs is EXPSPACE-complete, and that these problems become PSPACE-complete for OMQs with a linear Horn ontology and an atomic query, and also a positive query in the cases of FO(<)- and FO(<,\equiv)-rewritability. Further, we consider FO(<)-rewritability of OMQs with a binary-clause ontology and identify OMQ classes, for which deciding it is PSPACE-, Pi_2^p- and coNP-complete.

description: Recently, M. Badger and R.

Answering a question of Badger-Schul, we show that the converse is not true. Given $ε> 0$, we construct a Radon probability measure on $[0,1]^{2} \subset \mathbb{R}^{2}$ with the properties that $J_{1}(x) \leq ε$ for all $x \in \operatorname{spt} μ$, but nevertheless the $1$-dimensional lower density of $μ$ vanishes almost everywhere. In particular, $μ$ is purely $1$-unrectifiable.

Frente a esto, empezaron a generarse múltiples campañas comunicativas y políticas públicas para garantizar que los derechos de las personas en condición de discapacidad fueran mayormente impactantes y que a esta población se le garantizarán en pleno sus derechos. Por lo tanto, este trabajo de investigación busca hacer una descripción de las distintas campañas de comunicación y/o estrategias publicitarias [spots – piezas de comunicación públicas], para las personas con discapacidad, estableciendo un análisis de persuasión frente a las mismas, desde la ruta central o de la ruta periférica. Lo que buscamos encontrar, es si estas estrategias están encaminadas en persuadir al público objetivo, o si por el contrario, hace falta una ruta estratégica para diseñar desde distintos ámbitos públicos las estrategias publicitarias y de comunicación para esta población en Colombia.
description: Inclusion is a speech that throughout the years has been reinforced from the social sphere and even more from the constitutional one, developing from different positions looking to specific actions to help a minor part of the population that for years have struggled to get this needed attention. Because of this, several communication campaigns started to get generated including public policies to guarantee rights of people with any type of disabilities so they could have a bigger impact and coverage in all their rights in full. Therefore, this research paperwork is seeking to analyze the different communication campaigns and public advertisement strategies such as (spot, audio-visual and communication pieces) for people with any disabilities, establishing a persuasive approach regarding its central path or the peripheral path. What we are looking to find, is if these strategies are well constructed and its course indeed persuades the objective public as a fact or, in the contrary, is lacking of an strategic path to design from different public views the advertisement and communication strategies for this part of the population in Colombia.

description: The performance of the photovoltaics systems depends on the weather, specifically on the irradiance
and temperature, features that reveal a 99 % of the system performance. The design of the photovoltaic system
depends on the veracity, for this reason it is significant to put photovoltaics panels in different locations. This
research shows an analysis on the influence and efficiency of irradiance and temperature in different locations in the
central region of Colombia. The characterization of the solar energy potential (irradiance) is done in four locations of
the central region of Colombia where different environmental conditions can be found, likewise it is intended to do a
characterization of the room temperature of each place that affects the panel, and finally do a characterization of the
panel efficiency under the irradiance and temperature conditions of the four places already set. Curves IV and PV
were built for the three panels in each location, there were 743 measurements in total, an average of 62 measurements
in each city. The systematization, analysis and results show efficiencies that allow us to classify the places and
analyze the irradiance and temperature within the output of the power panel.

description: A previous work of ours found the best agreement between EUV light curves observed in an active region core (with evidence of super-hot plasma) and those predicted from a model with a random combination of many pulse-heated strands with a power-law energy distribution. We extend that work by including spatially resolved strand modeling and by studying the evolution of emission along the loops in the EUV 94 A and 335 A channels of the Atmospheric Imaging Assembly on-board the Solar Dynamics Observatory. Using the best parameters of the previous work as the input of the present one, we find that the amplitude of the random fluctuations driven by the random heat pulses increases from the bottom to the top of the loop in the 94 A channel and, viceversa, from the top to the bottom in the 335 A channel. This prediction is confirmed by the observation of a set of aligned neighbouring pixels along a bright arc of an active region core. Maps of pixel fluctuations may therefore provide easy diagnostics of nano-flaring regions.

description: The inclusion of kinetic effects into fluid models has been a long standing problem in magnetic reconnection and plasma physics. Generally the pressure tensor is reduced to a scalar which is an approximation used to aid in the modeling of large scale global systems such as the Earth's magnetosphere. This unfortunately omits important kinetic physics which have been shown to play a crucial role in collisionless regimes. The multi-fluid 10-moment model on the other-hand retains the full symmetric pressure tensor. The 10-moment model is constructed by taking moments of the Vlasov equation up to second order, and includes the scalar density, the vector bulk-flow, and the symmetric pressure tensor for a total of 10 separate components. Use of the multi-fluid 10-moment model requires a closure which truncates the cascading system of equations. Here we look to leverage data-driven methodologies to seek a closure which may improve physical fidelity of the 10-moment multi-fluid model in collisionless regimes. Specifically we use the Sparse Identification of Nonlinear Dynamics (SINDy) method for symbolic equation discovery to seek the truncating closure from fully kinetic particle-in-cell simulation data, which inherently retains the relevant kinetic physics. We verify our method by reproducing the 10-moment model from the PIC particle data and use the method to generate a closure truncating the 10-moment model which is analyzed through the nonlinear phase of reconnection.

description: As Photovoltaics (PV) has been recognized as one of the major renewable energy sources to be used on a large scale to contribute to solving the energy challenges faced by South Africa, one of the most fundamental questions is which technology is best to deploy in specific areas in order to achieve the highest energy yield. This paper reports on the energy yield monitoring of various PV technologies operating under different deployment configurations at the Outdoor Research Facility (ORF) at the Nelson Mandela Metropolitan University, Port Elizabeth. I-V characteristic data measured with a high temporal resolution was used to directly compare the performance and device parameters of the various PV technologies under varying meteorological conditions. In addition, the energy yield and performance trends at high temporal resolution based on the I-V characteristics and meteorological conditions is discussed. Preliminary results confirm the benefit of energy yield gain by utilizing single-axis tracking and application of an appropriate module cleaning routine to reduce the effects of soiling.

description: Spectral tuning of solar simulators is a well-known procedure, used in the experimental practice for
years with multi-junction cells for concentrating photovoltaics (CPV) and space photovoltaic (PV) applications.
Multi-junction structures are also used in second generation thin-film PV modules (for example in a-Si:H
compounds). A dedicated international standard procedure (IEC 60904-1.1) is in view of publication, describing the
“how-to” for current-voltage characterization of multi-junction PV cells and modules: thereafter spectral tuning will
need to become soon a widely diffuse practice in research, research-and-development and development-andproduction
sites. With this in mind, the authors present here the upgrade of a Class AAA large area pulsed solar
simulator to allow spectral tuning by means of a set of high power LEDs. They revise the spectral tuning procedure
and show results on commercial modules. They give indications to quantify the new uncertainty contributions arising
from the non-uniformity of spectral irradiance and from the spectral mismatch, which affects not only the shortcircuit
current (which is the same as in single-junction devices), but also the fill factor and the open-circuit voltage in
multi-junction devices.

description: An experimental set up is presented for fast and precise outdoor characterization of PV modules. Low
light curves of electrical parameters of IV curves are determined by day to day natural variations of irradiation and
temperatures under field conditions. The temperature variation is additionally regulated by a test bench using a
silicone rubber heater which is in good thermal contact to the module. The precise IV characterization is achieved by
using so called self-reference algorithm. This approach reduces significantly the uncertainties for irradiation and
temperature which are operating at the cell’s pn-junction. Very low changes of module parameters are detectable. The
active heating element can also be used to achieve temperatures of hot climate zones and allows electrical tests of PV
modules for nearly each temperate zone of the world.

description: Accuracy and reliability in the determination of series resistance RS of PV devices is an important
issue, not only in industrial production environment, because of the parasitic and power consuming nature of this
intrinsic parameter, but also in measurement and test laboratories, due to its influence during the translation of
measured IV curves to reporting conditions.
This work follows standard IEC 60891 ed.2 (2009) for the determination of the internal series resistance and focuses
on the repeatability of the result and its uncertainty. The latter is studied in particular considering a possible variation
of device temperature during the I-V measurements for the RS determination. An analytical expression is derived for
quantifying the additional apparent series resistance RS due to temperature variation. Experimental results confirm
the derived expression.
Although the standard IEC 60891 ed.2 (2009) states that a constant device temperature is required during the I-V
curve measurements, it sets the limits for stability within ±2°C. Here it is found that this would lead to a deviation
RS, which is comparable to RS itself. However, if the temperature variation is limited to ±0.1°C, which is achievable
on pulsed solar simulators, the deviation of RS is limited to ±5%. The repeatability of RS was found to be typically
better than 5%. Conservatively, simply adding the two components, the overall combined expanded uncertainty
(k=2) for the determination of RS is found to be ±10%. It is recommended to revise IEC 60891 ed.2 concerning the
device temperature during determination of RS.
Quark ACM with topologically generated gluon mass

description: We investigate the effect of a small, gauge-invariant mass of the gluon on the anomalous chromomagnetic moment of quarks (ACM) by perturbative calculations at one loop level. The mass of the gluon is taken to have been generated via a topological mass generation mechanism, in which the gluon acquires a mass through its interaction with an antisymmetric tensor field $B_{μν}$. For a small gluon mass $(<10$ MeV), we calculate the ACM at momentum transfer $q^2=-M_Z^2$. We compare those with the ACM calculated for the gluon mass arising from a Proca mass term. We find that the ACM of up, down, strange and charm quarks vary significantly with the gluon mass, while the ACM of top and bottom quarks show negligible gluon mass dependence. The mechanism of gluon mass generation is most important for the strange quarks ACM, but not so much for the other quarks. We also show the results at $q^2=-m_t^2$. We find that the dependence on gluon mass at $q^2=-m_t^2$ is much less than at $q^2=-M_Z^2$ for all quarks.

description: We have developed a highly accelerated thermal cycling (HATC) test. As previously reported, we have
improved a thermal cycling (TC) test to shorten testing time by increasing the number of TC per unit time in addition
to light irradiation. In this study, we investigated further enhancement of stress to reduce testing time for the TC test.
From an analysis by using the Eyring model, we found that the temperature difference, T, largely affects the
acceleration of TC testing. An effect of T was confirmed by performing an HATC test with T of 165oC. The result
showed that the HATC test degraded a PV module nearly five times faster than by the simple repetition of a TC test
in accordance with International Electrotechnical Commission (IEC) qualifications. No acceleration effect was
confirmed through examination of light irradiation stress.

Quality and Sustainability in Manufacturing and Recycling

description: Flexible backsheets form the exterior layer and protect internal module components including the
encapsulant, silicon cells and electrical contacts. Mechanical requirements for the backsheet focus on adhesion and
resistance to mechanical damage during processing, installation and long term environmental stresses. As the key
electrical insulator, the electrical requirements involve resistance to the high voltages present in typical PV
installations and occasional voltage spikes that can be experienced. Chemical transport properties of the backsheet,
including water and oxygen transport, can impact corrosion rates and may be associated with power loss. Optical
properties include reflectivity and gloss which can impact light capture and appearance.
A major consideration for backsheet selection is durability and protecting the module. Considering that greater than
25 year outdoor performance is expected from PV modules, backsheets need to maintain these key properties and
protect the module over its expected life. For component test protocols, these efforts have centered on exposure
conditions appropriate for expected outdoor exposure. For module testing, additional sequential and weathering
exposure conditions have been defined which assess the impact of real world conditions on the appropriate module
constructions. Development of these tests has been guided by our work in assessing PV module performance in the
field through field visits and analysis of fielded modules using advanced analytical methods. Recent work aimed at
new correlations of accelerated testing and outdoor performance is described. We also examine a range of backsheet
types and assess the impact on properties for relevant differences in constructions, compositions and thicknesses.

description: Point defects in the binary group-IV monochalcogenide monolayers of SnS, SnSe, GeS, GeSe are investigated using density-functional-theory calculations. Several stable configurations are found for oxygen defects, however we give evidence that these materials are less prone to oxidation than phosphorene, with which monochalcogenides are isoelectronic and share the same orthorhombic structure. Concurrent oxygen defects are expected to be vacancies and substitutional oxygen. We show that it is energetically favorable oxygen be incorporated into the layers substituting for a chalcogen (O S/Se defects), and different from most of the other defects investigated, this defect preserves the electronic structure of the material. Thus, we suggest that annealing treatments can be useful for the treatment of functional materials where loss mechanisms due to the presence of defects are undesirable.
