Quality and Sustainability in Manufacturing and Recycling

description: 31st European Photovoltaic Solar Energy Conference and Exhibition; 2449-2452
description: For the classification of solar simulators the spectral irradiance is one relevant criterion. Array
spectrometers are often used for this purpose. We developed a compact and portable spectrometer instrument
specifically for flash and steady-state solar simulators. It is commercially available since 2011 under the name
FlashSpec. Multiple experiments were performed to quantify several source of uncertainty.
To ensure the validity of an external calibration, repeatability measurements were performed on a weekly basis.
Noise equivalent irradiation was determined for the shortest integration time of 0.6ms. Non-linearity was found to be
wavelength independent. Straylight internal to the spectrometer was investigated with LEDs and filters.

description: Many modern PV modules have a much higher fill factor than the P-V curves used in standard test
procedures for PV inverters. A high fill factor makes a PV module more susceptible to MPP tracking losses. Single
phase grid connected PV inverters without DC link always have a ripple on the DC side. This ripple makes an ideal
MPP tracking impossible, because even if the DC voltage is optimized, the operating point always oscillates around
the MPP. A high fill factor increases the losses caused by this effect. This paper shows that these losses can be as
high as or even exceed the losses caused by the inverter’s conversion efficiency. This is done by data obtained with a
simulation model, but also with actual measurements performed on a real PV inverter.
Learning a Restricted Boltzmann Machine using biased Monte Carlo sampling

description: Restricted Boltzmann Machines are simple and powerful generative models that can encode any complex dataset. Despite all their advantages, in practice the trainings are often unstable and it is difficult to assess their quality because the dynamics are affected by extremely slow time dependencies. This situation becomes critical when dealing with low-dimensional clustered datasets, where the time required to sample ergodically the trained models becomes computationally prohibitive. In this work, we show that this divergence of Monte Carlo mixing times is related to a phenomenon of phase coexistence, similar to that which occurs in physics near a first-order phase transition. We show that sampling the equilibrium distribution using the Markov chain Monte Carlo method can be dramatically accelerated when using biased sampling techniques, in particular the Tethered Monte Carlo (TMC) method. This sampling technique efficiently solves the problem of evaluating the quality of a given trained model and generating new samples in a reasonable amount of time. Moreover, we show that this sampling technique can also be used to improve the computation of the log-likelihood gradient during training, leading to dramatic improvements in training RBMs with artificial clustered datasets. On real low-dimensional datasets, this new training method fits RBM models with significantly faster relaxation dynamics than those obtained with standard PCD recipes. We also show that TMC sampling can be used to recover the free-energy profile of the RBM. This proves to be extremely useful to compute the probability distribution of a given model and to improve the generation of new decorrelated samples in slow PCD-trained models.

description: This paper deals with turbo-equalization for coded data transmission over intersymbol interference (ISI) channels. We propose a message-passing algorithm that uses the expectation-propagation rule to convert messages passed from the demodulator-decoder to the equalizer and computes messages returned by the equalizer by using a partial Gaussian approximation (PGA). Results from Monte Carlo simulations show that this approach leads to a significant performance improvement compared to state-of-the-art turbo-equalizers and allows for trading performance with complexity. We exploit the specific structure of the ISI channel model to significantly reduce the complexity of the PGA compared to that considered in the initial paper proposing the method.

description: Vaccine hesitancy is a complex issue with psychological, cultural, and even societal factors entangled in the decision-making process. The narrative around this process is captured in our everyday interactions; social media data offer a direct and spontaneous view of peoples' argumentation. Here, we analysed more than 500,000 public posts and comments from Facebook Pages dedicated to the topic of vaccination to study the role of moral values and, in particular, the understudied role of the Liberty moral foundation from the actual user-generated text. We operationalise morality by employing the Moral Foundations Theory, while our proposed framework is based on recurrent neural network classifiers with a short memory and entity linking information. Our findings show that the principal moral narratives around the vaccination debate focus on the values of Liberty, Care, and Authority. Vaccine advocates urge compliance with the authorities as prosocial behaviour to protect society. On the other hand, vaccine sceptics mainly build their narrative around the value of Liberty, advocating for the right to choose freely whether to adhere or not to the vaccination. We contribute to the automatic understanding of vaccine hesitancy drivers emerging from user-generated text, providing concrete insights into the moral framing around vaccination decision-making. Especially in emergencies such as the Covid-19 pandemic, contrary to traditional surveys, these insights can be provided contemporary to the event, helping policymakers craft communication campaigns that adequately address the concerns of the hesitant population.

description: For precise monitoring of PV grid connected systems, a vast number of parameters have to be recorded.
Therefore, it is very important to use a data acquisition system in order to collect data concerning the installed system
performance. In this paper we have developed a new low-cost data acquisition system. It is based on an open-source
Arduino microcontroller prototyping platform. The proposed system meets all of the appropriate requirements in terms of
accuracy and reliability with a resolution of 15-bits, it consists of a set of sensors for measuring both meteorological
(radiation intensity, ambient temperature, wind speed and direction), cells temperature and electrical parameters (DC
photovoltaic voltage at inverter input and AC voltage and output from it). The collected data are first conditioned using
precision electronic circuits, then processed and stored by the Arduino card in an SD card, not requiring any external
computer. The system allows local storage and distance data transfer through Internet. The proposed solution is easy to
build, has low energy consumption and has enough flexibility for potential future modifications.

description: We present a single barrier system to generate pure valley-polarized current in monolayer graphene. A uniaxial strain is applied within the barrier region, which is delineated by localized magnetic field created by ferromagnetic stripes at the regions boundaries. We show that under the condition of matching magnetic field strength, strain potential, and Fermi energy, the transmitted current is composed of only one valley contribution. The desired valley current can transmit with zero reflection while the electrons from the other valley are totally reflected. Thus, the system generates pure valley-polarized current with maximum conductance. The chosen parameters of uniaxial strain and magnetic field are in the range of experimental feasibility, which suggests that the proposed scheme can be realized with current technology.

description: We present simulations of the very high energy (VHE) gamma-ray light curve of the Crab pulsar as observed by the Cherenkov Telescope Array (CTA). The CTA pulse profile of the Crab pulsar is simulated with the specific goal of determining the accuracy of the position of the interpulse. We fit the pulse shape obtained by the MAGIC telescope with a three-Gaussian template and rescale it to account for the different CTA instrumental and observational configurations. Simulations are performed for different configurations of CTA and for the ASTRI mini-array. The northern CTA configuration will provide an improvement of a factor of ~3 in accuracy with an observing time comparable to that of MAGIC (73 hours). Unless the VHE spectrum above 1 TeV behaves differently from what we presently know, unreasonably long observing times are required for a significant detection of the pulsations of the Crab pulsar with the high-energy-range sub-arrays. We also found that an independent VHE timing analysis is feasible with Large Size Telescopes (LSTs). CTA will provide a significant improvement in determining the VHE pulse shape parameters necessary to constrain theoretical models of the gamma-ray emission of the Crab pulsar. One of such parameters is the shift in phase between peaks in the pulse profile at VHE and in other energy bands that, if detected, may point to different locations of the emission regions.

description: In this work, we study for the first time the thermal evolution of twin star pairs, i.e., stars that present the same mass but different radius and compactness. We collect available equations of state that give origin to a second branch of stable compact stars with quarks in their core. For each equation of state, we investigate the particle composition inside stars and how differently each twin evolves over time, which depends on the central density/pressure and consequent crossing of the threshold for the Urca cooling process. We find that, although the general stellar thermal evolution depends on mass and particle composition, withing one equation of state, only twin pairs that differ considerably on compactness can be clearly distinguished by how they cool down.

description: We introduce a new intrinsic measure of local curvature on point-cloud data called diffusion curvature. Our measure uses the framework of diffusion maps, including the data diffusion operator, to structure point cloud data and define local curvature based on the laziness of a random walk starting at a point or region of the data. We show that this laziness directly relates to volume comparison results from Riemannian geometry. We then extend this scalar curvature notion to an entire quadratic form using neural network estimations based on the diffusion map of point-cloud data. We show applications of both estimations on toy data, single-cell data, and on estimating local Hessian matrices of neural network loss landscapes.

description: Stochasticity plays a fundamental role in various biochemical processes, such as cell regulatory networks and enzyme cascades. Isothermal, well-mixed systems can be modelled as Markov processes, typically simulated using the Gillespie Stochastic Simulation Algorithm (SSA). While easy to implement and exact, the computational cost of using the Gillespie SSA to simulate such systems can become prohibitive as the frequency of reaction events increases. This has motivated numerous coarse-grained schemes, where the "fast" reactions are approximated either using Langevin dynamics or deterministically. While such approaches provide a good approximation when all reactants are abundant, the approximation breaks down when one or more species exist only in small concentrations and the fluctuations arising from the discrete nature of the reactions becomes significant. This is particularly problematic when using such methods to compute statistics of extinction times for chemical species, as well as simulating non-equilibrium systems such as cell-cycle models in which a single species can cycle between abundance and scarcity. In this paper, a hybrid jump-diffusion model for simulating well- mixed stochastic kinetics is derived. It acts as a bridge between the Gillespie SSA and the chemical Langevin equation. For low reactant reactions the underlying behaviour is purely discrete, while purely diffusive when the concentrations of all species is large, with the two different behaviours coexisting in the intermediate region. A bound on the weak error in the classical large volume scaling limit is obtained, and three different numerical discretizations of the jump-diffusion model are described. The benefits of such a formalism are illustrated using computational examples.

More precisely, if P_n(f) is the number of its isolated periodic points of period n (counted with multiplicity), then P_n(f) grows at most exponentially fast with respect to n and the exponential rate is at most equal to the algebraic entropy of f. Further estimates are given when X is a surface. Among the techniques introduced in this paper, the h-dimension of the density between two arbitrary positive closed currents on a compact Kaehler surface is obtained.

description: PV plants require a monitorization of their electrical parameters to achieve its best performance.
Lately, it is more and more common that SCADA systems monitor currents and voltages even of every single string.
These measurements which use to be stored instantaneously with a frequency like the one established on inverters
and energy meters (usually each 10, 15, 20 or 60 minutes) are useful to detect faults. Unfortunately, it is not taken
advantage of them to characterize the PV arrays. A better option would be to exploit this monitoring capability not
only to detect operation failures, but also to characterize the PV strings/arrays. In order to implement this
characterization it is needed to use the adequate devices to measure voltages and currents and determine which should
be the optimal frequency to store data, depending on they are instantaneous or mean values. This paper presents the
results of the DC monitoring of a grid-connected PV array of 5.8 kWp, installed on the headquarters of the Instituto
de Energía Solar of the Universidad Politécnica de Madrid (IES-UPM), located in the Campus Sur of Vallecas
(Madrid), which allows characterizing the PV arrays power. To study the relation between sampling frequency and its
impact in the accuracy of the power averages each 1’, 5’, 10, and 15’ have been calculated from instantaneous
measurements, and they have been analysed to evaluate which is the more adequate sampling rate for instantaneous
and mean values.

description: Based on a stochastic model for intermittent fluctuations in the boundary region of magnetically confined plasmas, an expression for the level crossing rate is derived from the joint distribution of the process and its derivative. From this the average time spent by the process above a certain threshold level is obtained. This provides novel predictions of plasma-wall interactions due to transient transport events associated with radial motion of blob-like structures in the scrape-off layer.

Tunable nonlinear coherent perfect absorption and reflection in cavity QED

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose and analyze a scheme for realizing tunable coherent perfect absorption (CPA) and reflection (CPR) in a three-level $Λ$-type atom-cavity system. With EIT-type interference induced by a coherent coupling laser, the scheme provides a new method of attaining tunable near CPR at two-photon resonance. By different coupling strength, the system can be excited from linear CPA regime into nonlinear even bistable CPA regime without changing the frequency of the probe field, where the hysteresis cycle of the bistability is controllable. In addition, the CPA regime can be transferred into the near CPR regime with controllable atomic coherence and linear absorption induced by an incoherent pump field. Our work suggests a mechanism for manipulation on extreme absorption (0% and 100%), which can potentially be applied in logical gates and optical switches for coherent optical computing and communication.

description: We demonstrate that in confined plasmonic metal structures subject to ultra-fast laser excitation electron thermal diffusion can provide relaxation faster than the energy transfer to the lattice. This relaxation occurs due to excitation of nanometer-sized hot spots in the confined structure and the sensitivity of its optical parameters to the perturbation in these regions. Both factors become essential when the plasmonic resonance condition is met for both excitation and detection. A pump-probe experiment on plasmonic gold lattices shows sub-picosecond relaxation with the characteristic times well-described by a two-temperature model. The results suggest that dynamical optical response in plasmonic structures can be tuned by selection of the structural geometry as well as the choice of wavelength and polarization of the excitation and detection light.

description: The use of solar energy as a source for pumping water is one of the promising areas in the
photovoltaic (PV) application. The energy of photovoltaic pumping systems (PVPS) can be widely improved by
employing an MPPT algorithm. This will lead consequently to maximize the electrical motor speed of the system.
This paper presents a modified incremental conductance (IncCond) MPPT algorithm with direct control method
applied to a standalone PV pumping system. The influence of the algorithm parameters on system behavior is
investigated and compared with the traditional (INC) method. The studied system consists of a PV panel, a DCDC
boost converter, and a PMDC motorpump. The simulation of the system by MATLAB-SIMULINK is carried
out. Simulation results found are satisfactory.

Existing techniques often require piezoelectric materials with an external radiofrequency excitation that are not readily integrated into existing CMOS infrastructures, while non-piezoelectric demonstrations have been inefficient. In this work, we explore the optomechanical generation of coherent phonons in a suspended 2D silicon phononic crystal cavity with a guided mode around 6.8 GHz. By incorporating an air-slot into this cavity, we turn the phononic waveguide into an optomechanical platform that exploits localized photonic modes resulting from inherent fabrication imperfections for the transduction of mechanics. Such a platform exhibits very fine control of phonons using light, and is capable of coherent self-sustained phonon generation via mechanical lasing around 6.8 GHz. The ability to generate high frequency coherent mechanical vibrations within such a simple 2D CMOS-compatible system could be a first step towards the development of sources in phononic circuitry and the coherent manipulation of other solid-state properties.

description: In this paper we set a framework in which experiments whose goal is to test QED predictions can be used in a more general way to test non-linear electrodynamics (NLED) which contains low-energy QED as a special case. We review some of these experiments and we establish limits on the different free parameters by generalizing QED predictions in the framework of NLED. We finally discuss the implications of these limits on bound systems and isolated charged particles for which QED has been widely and successfully tested.

description: A linear programming model for a typical dryland farm in the 1000mm rainfall zone of Mali, West Africa indicates that, despite substantial variability in yields due to weather, a "safety-first" condition on staple food production constrains profit maximization only in the case of much smaller than average farms. Tied-ridge cultivation methods will reduce erosion damage, improve food security for small farms, and increase incomes if expected costs and yields are realized. Even without an immediate yield gain, tied-ridge cultivation would be economically justified by the reduction provided in future erosion-caused losses in soil productivity. The paper begins by summarizing the physical characteristics of dryland agriculture in Mali. Next, a brief description of emerging soil- and moisture-conserving technology is provided. Lastly, a whole-farm planning model is presented and initial results of a case study involving the economics of improved resource management are given.

description: We propose a magnetic topological transistor based on MnBi$_{2}$Te$_{4}$, in which the "on" state (quantized conductance) and the "off" state (zero conductance) can be easily switched by changing the relative direction of two adjacent electric fields (parallel vs. antiparallel) applied within a two-terminal junction. We explain that the proposed magnetic topological transistor relies on a novel mechanism due to the interplay of topology, magnetism, and layer degrees of freedom in MnBi$_{2}$Te$_{4}$. Its performance depends substantially on film thickness and type of magnetic order. We show that "on" and "off" states of the transistor are robust against disorder due to the topological nature of the surface states. Our work opens an avenue for applications of layer-selective transport based on the topological van der Waals antiferromagnet MnBi$_{2}$Te$_{4}$.

description: The emission of volatile organic compounds (VOCs) from plants is associated with biotic and abiotic stress and depends on the plant species, organs, and developmental stage. Insects use VOCs to locate their host plants and their behavior is heavily influenced by the chemical profile of each at its current phenological stage. The brown marmorated stink bug Halyomorpha halys (Hemiptera: Pentatomidae) is a highly polyphagous pest that causes significant damage to tree, vegetable, and ornamental crops worldwide. The volatile profiles of five hosts of H. halys were compared for common substances to provide insight into this insect’s extreme polyphagy. Headspace collection of volatile substances was performed for five hosts of H. halys by gas chromatography – mass spectrometry (GC-MS), and their VOC profiles were compared. The results show that, although the volatile profiles of the host plants differ substantially, 13 out of the 68 identified compounds were shared. These results suggest that host recognition by H. halys is likely driven by a combination of attractive and possibly repellent compounds that work synergistically which is the first step toward decoding this pest’s polyphagous nature.

description: Currently the improvement of stand-alone PV power systems characteristics, including increase of
their service life is the actual direction of ground solar power development. The analysis of stand-alone PV power
systems efficiency with the use of ultra capacitors is carried out by the means of mathematical modeling. The
obtained data shows that the use of ultra capacitors as additional short-term energy storage devices in stand-alone
PV power systems contributes to considerable increase of storage batteries lifetime and the total system operating
time.
Coherent Perfect Absorption induced by the nonlinearity of a Helmholtz resonator

description: In this work, we analytically report Coherent Perfect Absorption induced by the acoustic nonlinear response of a Helmholtz Resonator side loaded to a waveguide. In particular, we show that this two-port acoustic system can perfectly absorb two high amplitude symmetric incident waves when the additive nonlinear losses in the HR, induced by the jet flow separation, together with the weak linear viscothermal losses of the HR balance the radiation losses to the waveguide. For the case of the one-sided incidence configuration, this condition leads to an absorption equal to 0.5. This result, which is verified experimentally, is in a good agreement with an analytical nonlinear model of the impedance of the HR. The nonlinear control of perfect absorption using resonators will open new possibilities in the design of high amplitude sound attenuators for aero-engine applications.
