description: Renewable energy markets are subject to fast technical evolutions and a lack of qualified professional
structures. Nonetheless, good quality installations are essential for end customer satisfaction and sustainable market
growth. To define and structure quality requirements covering the whole market chain, the Belgian Federal Science
Policy financed the Q-Direct project, aiming at developing quality references in distributed generation.
An integrated methodology has been developed for six renewable energy technologies, to define common ambition
levels ensuring high quality from components and products for system design, installation and performance.
This led to a Microgeneration Quality Scheme for distributed renewable energy in Belgium, consisting of harmonized
quality requirements for a range of energy technologies, enabling product innovation and system combination, and
providing a basis for policymakers supporting policy and regulation. A dynamic quality improvement process was
launched through the exchanges with the sector. The process is market-driven by demand and policy-driven by
regulation. The second phase of the project is assessing paths towards implementation of such microgeneration a
quality scheme in Belgium and further links with EU standards and certification.

description: We report a dynamic light scattering study of the fluctuation modes in a thermotropic liquid crystalline mixture of monomer and dimer compounds that exhibits the twist-bend nematic ($\mathrm{N_{TB}}$) phase. The results reveal a spectrum of overdamped fluctuations that includes two nonhydrodynamic and one hydrodynamic mode in the $\mathrm{N_{TB}}$ phase, and a single nonhydrodynamic plus two hydrodynamic modes (the usual nematic optic axis or director fluctuations) in the higher temperature, uniaxial nematic phase. The properties of these fluctuations and the conditions for their observation are comprehensively explained by a Landau-deGennes expansion of the free energy density in terms of heliconical director and helical polarization fields that characterize the $\mathrm{N_{TB}}$ structure, with the latter serving as the primary order parameter. A "coarse-graining" approximation simplifies the theoretical analysis, and enables us to demonstrate quantitative agreement between the calculated and experimentally determined temperature dependence of the mode relaxation rates.

description: The performance and reliability of thin film silicon modules produced by Applied Materials’
SunFab™ Thin Film line have been investigated. The performance has been monitored in four locations,
Neustadt bei Coburg, Germany, Singapore, Phoenix, Arizona, and Santa Clara, California. In the hot locations,
SunFab panels produced >8 rel% more kWh per rated kWp than c-Si. This was due both to lower temperature
coefficients and higher low-light output. The performance was compared to predictions made by a PVsyst model
developed for SunFab modules. The actual performance exceeded the predicted performance by ~5rel%. The
outdoor light-induced degradation (LID) of SunFab modules has been monitored and shows a 15 rel% short-term
degradation, in alignment with expectations. SunFab modules were subjected to 50 humidity-freeze cycles, 2000
hours of damp heat, and 400 temperature cycles and passed both power and wet leakage resistance tests. Using an
internal levelized cost of electricity model, we predict that SunFab modules have an LCOE ~1 ¢/kWh lower than
that of c-Si in a location like Riyadh, Saudi Arabia. In 2011, projected BOS and SunFab module costs will
support an LCOE of ~13¢/kWh in hot sunny locations.

description: Hydrodynamics can be formulated in terms of a perturbative series in derivatives of the temperature, chemical potential, and flow velocity around an equilibrium state. Different formulations for this series have been proposed over the years, which consequently led to the development of various hydrodynamic theories. In this work, we discuss the relativistic generalizations of the perturbative expansions put forward by Chapman and Enskog, and Hilbert, using general matching conditions in kinetic theory. This allows us to describe, in a comprehensive way, how different out-of-equilibrium definitions for the hydrodynamic fields affect the development of the hydrodynamic perturbative series. We provide a perturbative method for systematically deriving the hydrodynamic formulation recently proposed by Bemfica, Disconzi, Noronha, and Kovtun (BDNK) from relativistic kinetic theory. The various transport coefficients that appear in BDNK (at first-order) are explicitly computed using a new formulation of the relaxation time approximation for the Boltzmann equation. Assuming Bjorken flow, we also determine the hydrodynamic attractors of BDNK theory and compare the overall hydrodynamic evolution obtained using this formulation with that generated by the Israel-Stewart equations of motion and also kinetic theory.

description: At present, the applications of solar cells in terms of photovoltaic (PV) power systems
have been widely installed throughout the country, particularly in Thailand. Most PV power systems have been
carried out in rural areas of Thailand. Even though their systems can be installed in urban areas, lack of an
interesting from owner households to install the PV systems. This is because the national grid system from the
electric utilities can be easily accessed. Nevertheless, correct knowledge of advantage for PV systems technology
should be provided to people who have used the conventional electricity and have lived in the city. In practice, PV
power systems can be applied in everywhere, especially in the city that these systems can be installed with on grid
types. To be a successful implementation of PV city program in Thailand, the useful information process of
dissemination for PV programs in the urban city is very necessary. It is essential to consider the strategies for carry
out of a PV city project to ensure that it could be more successful. This paper presents a practically strategic model
for PV dissemination in a Thai university of technology where is located nearly in Bangkok, the capital city of
Thailand, and many applications of PV systems have been also installed at this university. In fact, the university
can be an important key player in this model and must has the responsibility to provide correct knowledge of PV
system applications to people who have lived in urban and industrialized areas. Accordingly, the key persons and
their roles including some organizations in a model will be discussed. The sample model can be applied in other
places, not just in a university.

description: The concept of cities as potential photovoltaic power plants is rapidly gaining prominence, but until
now there has been no large scale study of the impacts of such development on urban fabric and infrastructure, or on
inhabitants. This book, based on wide-ranging studies supported by the European Commission and International
Energy Agency, is the first to properly address these issues. It sets out by looking at the implications on planning
policy of PV in the urban environment, and giving an overview of the implementation and occupation processes. It
then moves on to present detailed case studies from a range of European cites, examining the role of large scale PV
installations in urban renewal and new urban area development stretching back over 15 years. It ends with a review of
technical guidelines for PV, and regulation/legalities surrounding planning, building and grid connection. The book
will form an essential resource for planners and developers who are considering including large scale PV in their
plans and who want to understand what has (or hasn’t) worked, and why.

description: In this paper the microwave-detected photoconductance decay (MWPCD) is evaluated in detail to allow a reliable determination of the interstitial iron content with high spatial resolution. The effect of the iron-boronpair dissociation within a surface passivated solar grade silicon wafer on the MWPCD signal is demonstrated. An advanced evaluation method of the MWPCD signal is applied, revealing the minority carrier lifetime as a function of the excess carrier density. After the MWPCD signal is calibrated by a quasi-steady-state photoconductance (QSSPC) measurement, the interstitial iron content is calculated from the difference in the lifetime in both states of the ironboron pairs. The interstitial iron content of a multicrystalline silicon wafer is mapped, showing a reduced content at the grain boundaries due to gettering. At the edge of a Czochralski silicon ingot an increasing interstitial iron content is found, which is caused by indiffusion from the gas ambient during ingot pulling.

description: Powerful and efficient optical frequency combs in the mid-infrared (MIR) spectral region are highly desirable for a broad range of applications. Despite extensive efforts utilizing various techniques, MIR frequency comb sources are still lacking power, efficiency, or bandwidth for many applications. Here, we report the generation of an intrinsically locked frequency comb source centered at 4.18 μm from an optical parametric oscillator (OPO) operating in the simulton regime, in which formation of purely quadratic solitons lead to enhanced performance. We show advantages of operation in the simulton regime in direct experimental comparisons to the conventional regime, which are also supported by simulation and theory. We achieve 565 mW of average power, 900 nm of instantaneous 3-dB bandwidth, 350% of slope efficiency, and 44% of conversion efficiency; a performance that is superior to previous OPO demonstrations and other sources in this wavelength range. This work opens a new avenue toward MIR frequency comb generation with high power and efficiency and suggests the great potential of soliton generation based on quadratic nonlinearity in the MIR spectral region.

The invisible hand and the rational agent are behind bubbles and crashes

description: The substantial turmoil created by both 2000 dot-com crash and 2008 subprime crisis has fueled the belief that the two classical paradigms of economics, which are the invisible hand and the rational agent, are not appropriate to describe market dynamics and should be abandoned at the benefit of alternative new theoretical concepts. At odd with such a view, using a simple model of choice dynamics from sociophysics, the invisible hand and the rational agent paradigms are given a new legitimacy. Indeed, it is sufficient to introduce the holding of a few intermediate mini market aggregations by agents sharing their own private information, to recenter the invisible hand and the rational agent at the heart of market self regulation including the making of bubbles and their subsequent crashes. In so doing, an elasticity is discovered in the market efficiency mechanism due to the existence of agents anticipation. This elasticity is found to create spontaneous bubbles, which are rationally founded, and at the same time, it provokes crashes when the limit of elasticity is reached. Although the findings disclose a path to put an end to the bubble-crash phenomena, it is argued to be rationality not feasible.

description: Major global events during the Oligocene epoch included a climatic change from warm “greenhouse” to a cooler “icehouse” that was accompanied by the onset of Antarctic glaciation. These events led to decline in water temperature, salinity, nutrient supply and oxygen levels, and the extinction of some major fauna and flora. Within the study area, during this epoch, the shrinkage of the Neotethys and the development of the Paratethys, the collision of Arabia with Eurasia and the development of the Zagros mountains and opening of the Red Sea which led eventually to the separation of Arabia from Africa were witnessed. Oligocene sediments are absent from most parts of the Arabian Plate but are well-preserved in western and southwestern Iran. The most well-developed strata are the coral reefs of the Kirkuk Group in northern Iraq and the shallow water carbonates of the Asmari Formation in southwestern Iran. The study area also represents the birthplace of commercial hydrocarbons production in the Middle East from these sediments in Masjid-i-Sulaiman Field in Iran and Kirkuk Field in Iraq at the first decade of the last century. Future exploration for hydrocarbons potential should focus on identifying subsurface coral buildups or clastic strata that are equivalent to the Asmari Formation in Iran.Other Information Published in: Carbonates and Evaporites

description: This study addresses the impact of democracy on the stability of the banking system for a sample of 114 countries over the period 2000–2017. Our findings offer strong evidence for a U-shaped relationship between democracy and banking stability. Results also show that the way democratic institutions impact banking stability is highly dependent on their ability to implement effective anti-corruption policies. Controlling for countries’ income levels reveals that not all high-income countries are necessarily enjoying the positive effects of democracy on banking stability.

description: Organisations need to be innovative to be able to face the complexity and turbulence of the environmental forces and factors surrounding them. This is true in the case of all types of organisations, including SMEs, where innovations are essential for their survival and growth. As such, organisations need to nurture Innovative Work Behaviour (IWB) among their employees through different means. To achieve such ultimate goal, Workplaces Employees Learning can benefit many companies. Meanwhile, Workplace Learning (WPL) can improve the competencies and skills of employees and help their IWB. This research focuses on the role of WPL as a predictor of IWB among knowledge workers of SMEs in developing countries (i.e. Pakistan). Through convenient sampling technique, questionnaires were distributed among employees of 173 SMEs, resulting in 311 useable questionnaires. Data were analysed using Smart-PLS 3. The results indicated that WPL facilitated IWB among SME employees, with informal and incidental learning being the most critical predictors compared to formal means of learning. The research results reinforce the importance of WPL and IWB, and their implications are beneficial for SMEs and the academic society.Other Information Published in: Journal of the Knowledge Economy

description: Understanding factors affecting innovative financial decision-making involves the usage of more than one theory-driven model including those related to psychological behaviour (e.g. theory of planned behaviour). This study validates a conceptual framework extending the traditional financing model (TFM) and behavioural financial decision (BFD) to explain innovative financial decision-making utilising both qualitative and quantitative approaches. Based on a sample of 140 small tourism businesses, employing structured equation modelling, the findings reinforce the importance of the behavioural approach on innovative financial decision-making in small tourism businesses. The findings does not only make a respectable contribution the field, but also offer a practical evidence for the adaptation of the theory of planned behaviour in developing countries.Other Information Published in: Journal of the Knowledge Economy

description: Future generations of precise radial velocity (RV) surveys aim to achieve sensitivity sufficient to detect Earth mass planets orbiting in their stars' habitable zones. A major obstacle to this goal is astrophysical radial velocity noise caused by active areas moving across the stellar limb as a star rotates. In this paper, we quantify how stellar activity impacts exoplanet detection with radial velocities as a function of orbital and stellar rotational periods. We perform data-driven simulations of how stellar rotation affects planet detectability and compile and present relations for the typical timescale and amplitude of stellar radial velocity noise as a function of stellar mass. We show that the characteristic timescales of quasi-periodic radial velocity jitter from stellar rotational modulations coincides with the orbital period of habitable zone exoplanets around early M-dwarfs. These coincident periods underscore the importance of monitoring the targets of RV habitable zone planet surveys through simultaneous photometric measurements for determining rotation periods and activity signals, and mitigating activity signals using spectroscopic indicators and/or RV measurements at different wavelengths.

On the Relation between the Mysterious 21 Micrometer Emission Feature of Post-Asymptotic Giant Branch Stars and Their Mass Loss Rates

description: Over two decades ago, a prominent, mysterious emission band peaking at ~20.1 micrometer was serendipitously detected in four preplanetary nebulae (PPNe; also known as "protoplanetary nebulae"). So far, this spectral feature, designated as the "21 micrometer" feature, has been seen in 18 carbon-rich PPNe. The nature of the carriers of this feature remains unknown although many candidate materials have been proposed. The 21 micrometer sources also exhibit an equally mysterious, unidentified emission feature peaking at 30 micrometer. While the 21 micrometer feature is exclusively seen in PPNe, a short-lived evolutionary stage between the end of the asymptotic giant branch (AGB) and planetary nebula (PN) phases, the 30 micrometer feature is commonly observed in all stages of stellar evolution from the AGB through PPN to PNe phases. We derive the stellar mass loss rates (M_{loss}) of these 21 micrometer sources from their dust infrared (IR) emission, using the "2-DUST" radiative transfer code for axisymmetric dusty systems which allows one to distinguish the mass loss rates of the AGB phase (\dot{M_{AGB}}) from that of the superwind (\dot_{M_{SW}}) phase. We examine the correlation between \dot{M_{AGB}} or \dot_{M_{SW}} and the fluxes emitted from the 21 and 30 micrometer features. We find that both features tend to correlate with \dot{M_{AGB}}, suggesting that their carriers are probably formed in the AGB phase. The nondetection of the 21 micrometer feature in AGB stars suggests that, unlike the 30 micrometer feature, the excitation of the carriers of the 21 micrometer feature may require ultraviolet photons which are available in PPNe but not in AGB stars.

description: This work is aiming to develop photovoltaic modules from flexible polymer solar cells based on
materials existing on the market. In several steps the influence of the series resistance on polymer solar cell
performance is reviewed. Based on these experimental and theoretical investigations an optimal design for highly
efficient polymer solar modules is developed. As a next step to the realization of flexible polymer photovoltaics, the
proper technical approach to process larger area flexible substrates is required. In this case for production on
laboratory scale, the doctor blading technique and other coating techniques have been applied. The separation of
individual solar cells has been obtained by wet chemical etching and prospect is given for use of laser ablation. A
combination of coating and laser ablation techniques paves the way towards a roll-to-roll production.

description: Lanthanum-based perovskites (LaMnxCo1-xO3 (0 ≤ x ≤ 1)) were synthesized using a solution combustion synthesis technique with variable ratios of Co and Mn to investigate the surface property and electrocatalytic characteristics (stability and activity of catalyst) for methanol oxidation reaction (MOR), oxygen reduction reaction (ORR), and oxygen evolution reaction (OER) under alkaline medium (KOH). The structural, chemical, and morphological characterizations of the synthesized catalyst were performed by XRD, FTIR, SEM, TEM, and XPS techniques as a function of the Mn:Co elemental ratio. The time–temperature profile during the combustion process was also monitored to study the completion of the combustion reaction and to understand its impact on the structure of the perovskites. SEM/EDX and XPS analysis confirmed the formation of the targeted ratio of Mn and Co on the catalyst. Cyclic voltammetry (CV) and linear sweep voltammetry (LSV) results revealed that all perovskite samples with different Co:Mn ratios were active for ORR, OER, and MOR. The LaMnxCo1-xO3 perovskite with x = 0.4 showed the highest current density compared to the other samples toward all the electrocatalytic reactions under alkaline reaction conditions.

description: It is well known that the optical properties of spherical metal particles can be described with the Rayleigh approximation or rigorous Mie theory. But for the single metallic nanorods, a theory well capturing the fundamental resonance and scattering features is still absent. In this study, an analytical model is developed for the metallic nanorod, considering the longitudinally non-uniform conduction current and surface charges. With the circuit parameters deduced from the kinetic and electromagnetic energy of the nanorod, a formula which agrees well with the simulations has been suggested for the resonance wavelength of the fundamental longitudinal mode. Moreover, by introducing the radiative resistance to the circuit theory, the dipole moment, extinction spectrum, and near-field enhancement of the nanorod have been derived analytically and confirmed numerically. The results are important for understanding the optical properties of the metallic nanorods and provide a guideline for designing the light scattering and absorption.

The analysis is based on land cover (LC) classification (urban, green, and bare areas). The study found that bare areas had the highest mean LST values compared to the urban and green areas. The results show that the difference in temperatures between the bare areas and the urban areas ranges between 1 and 2 °C, between the bare areas and green areas ranges between 1 and 7 °C, and between the urban areas and green areas ranges between 1 and 5 °C. Furthermore, the LST values varied for each of the LULC categories, and hence some areas in the three categories had lower or higher LST values than in other categories. Hence, one category may not always have the highest LST value compared to other categories. The outcomes of this study may, therefore, have critical implications for urban planners who seek to mitigate UHI effects in arid and semi-arid urban areas.Other Information Published in: Environmental Earth Sciences

description: Digital dental models are widely used compared to dental impressions or plaster-dental models for occlusal analysis as well as fabrication of prosthodontic and orthodontic appliances. The digital dental model has been considered as one of the significant measures for the analysis of dental occlusion. However, the process requires more computation time with less accuracy during the re-establishment of dental occlusion. In this research, a modern method to re-establish dental occlusion has been designed using a Reconstructed-based Identical Matrix Point (RIMP) technique. The curvature of the dental regions has been reconstructed using distance mapping in order to minimize the computation time, and an iterative point matching approach is used for accurate re-establishment. Satisfactory restoration and occlusion tests have been analyzed using a dental experimental setup with high-quality digital camera images. Further, the high-quality camera images are converted to grayscale images for mathematical computation using MATLAB image processing toolbox. Besides, 70 images have been taken into consideration in which 30 planar view images has been utilized for experimental analysis. Indeed, based on the outcomes, the proposed RIMP outperforms overall accuracy of (91.50%) and efficiency of (87.50%) in comparison with conventional methods such as GLCM, PCR, Fuzzy C Means, OPOS, and OGS.Other Information Published in: Journal of Ambient Intelligence and Humanized Computing

description: The Sommerfeld boundary conditions, imposed on hyperbolic differential equations to obtain solutions in the form of outgoing waves, are formulated here so as to make explicit the role of an appropriate null vector field. When applied to the scalar and Maxwell equations, they lead to the asymptotic form of the energy-momentum tensor representing radiation as a null, perfect dust.

description: We fabricated the solar cell structure of n++-type poly silicon/oxygen-doped silicon quantum dots
superlattice (Si-QDSL:O)/p-type hydrogenated amorphous silicon/Electrode on a quartz substrate. The open-circuit
voltage and fill factor of 518 mV and 0.51 were obtained, respectively. This improvement was achieved by the
introduction of oxygen into the Si-QDSL layer and the reduction of the sheet resistance in the n++-type poly silicon
layer. The introduction of oxygen made the passivation effect on Si-QDs enhanced and leakage paths reduced.
Moreover, a substrate-type Si-QDSL:O solar cell was fabricated to remove the absorption loss in the n++-poly silicon
layer. As a result, the short-circuit current increased to 5.45 mA/cm2, suggesting that the Si-QDSL using an a-SiC:O
matrix has potential to operate enough as a carrier generation layer.

description: Here we report on small molecule organic solar cells based on a mixed ZnPc:C60 absorber layer embedded in p-i-nstructures.
First, the effect of purity of ZnPc on device performance was investigated. Second, the scale-up towards larger area
was studied. Two types of substrates were used as model substrates for scale-up: “Module A” is 200mmx200mm substrate with
cells connected in series (1x12cells in series, 8x3 cells in series) and “Module B” is a substrate of same size with 4 cells which are
not connected in series but which employ a metal-grid supported ITO anode in order to reduce anode sheet resistance. Single and
tandem cells were prepared with organic material of different purity. Single cells with high purity ZnPc were prepared on Module
B, tandem cells with lower purity ZnPc were prepared on Module A
Is There a Legal Path to Environmental Justice? Movement-building, strategic litigation, and a case study of Chicago’s General Iron dispute
Creators: name: Rorty, Ruby
Publisher: name: University of Chicago

description: This socio-legal research project assesses the role of litigation in environmental justice activist movements, using the planned relocation of the General Iron metal recycling plant in Chicago as a case study. To understand the modern environmental justice landscape, I conducted semi-structured interviews with ten environmental justice activists, plaintiffs, and attorneys, several of whom were involved in the General Iron issue specifically, to answer the research questions (1) What is the role of litigation in today’s environmental justice battles, especially on the Southeast Side of Chicago? and (2) What legal strategies are recommended by both the track record of environmental justice litigation in the courts and the needs of environmental justice grassroots movements as reported by organizers? I then analyzed the resulting transcripts for recurring patterns and insights. My interviews with community organizers on Chicago’s Southeast Side indicated that the General Iron issue exemplifies a dynamic wherein litigation is one of several elements of a grassroots environmental justice campaign, each essential but none more so than the others. In interviewing attorneys and reviewing the legal literature, I find that environmental justice lawsuits can catalyze political victories and bring attention and credibility to activist movements, even when they do not succeed in the courts. Based on both a review of legal literature and recent jurisprudence and my interviews, I ultimately propose that in the General Iron issue and future environmental justice battles on the Southeast Side, the community could draw on youth organizers to launch a youth plaintiff-led lawsuit employing both state constitutional claims and more traditional environmental law. Consistent with activists’ current use of the courts, this lawsuit should be accompanied by a media campaign and efforts to lobby local and state politicians for policy changes. With appropriately specific claims and compelling plaintiffs, such an effort could set new precedents, breathe life into Illinois’ historically limited environmental rights amendment, and succeed where past youth plaintiff cases have failed.

description: COVID-19 pandemic has created an extreme pressure on the global healthcare services. Fast, reliable, and early clinical assessment of the severity of the disease can help in allocating and prioritizing resources to reduce mortality. In order to study the important blood biomarkers for predicting disease mortality, a retrospective study was conducted on a dataset made public by Yan et al. in [1] of 375 COVID-19 positive patients admitted to Tongji Hospital (China) from January 10 to February 18, 2020. Demographic and clinical characteristics and patient outcomes were investigated using machine learning tools to identify key biomarkers to predict the mortality of individual patient. A nomogram was developed for predicting the mortality risk among COVID-19 patients. Lactate dehydrogenase, neutrophils (%), lymphocyte (%), high-sensitivity C-reactive protein, and age (LNLCA)—acquired at hospital admission—were identified as key predictors of death by multi-tree XGBoost model. The area under curve (AUC) of the nomogram for the derivation and validation cohort were 0.961 and 0.991, respectively. An integrated score (LNLCA) was calculated with the corresponding death probability. COVID-19 patients were divided into three subgroups: low-, moderate-, and high-risk groups using LNLCA cutoff values of 10.4 and 12.65 with the death probability less than 5%, 5–50%, and above 50%, respectively. The prognostic model, nomogram, and LNLCA score can help in early detection of high mortality risk of COVID-19 patients, which will help doctors to improve the management of patient stratification.Other Information Published in: Cognitive Computation

description: Nowadays, analyzing, detecting, and visualizing abnormal power consumption behavior of householders are among the principal challenges in identifying ways to reduce power consumption. This paper introduces a new solution to detect energy consumption anomalies based on extracting micro-moment features using a rule-based model. The latter is used to draw out load characteristics using daily intent-driven moments of user consumption actions. Besides micro-moment features extraction, we also experiment with a deep neural network architecture for efficient abnormality detection and classification. In the following, a novel anomaly visualization technique is introduced that is based on a scatter representation of the micro-moment classes, and hence providing consumers an easy solution to understand their abnormal behavior. Moreover, in order to validate the proposed system, a new energy consumption dataset at appliance level is also designed through a measurement campaign carried out at Qatar University Energy Lab, namely, Qatar University dataset. Experimental results on simulated and real datasets collected at two regions, which have extremely different climate conditions, confirm that the proposed deep micro-moment architecture outperforms other machine learning algorithms and can effectively detect anomalous patterns. For example, 99.58% accuracy and 97.85% F1 score have been achieved under Qatar University dataset. These promising results establish the efficacy of the proposed deep micro-moment solution for detecting abnormal energy consumption, promoting energy efficiency behaviors, and reducing wasted energy.Other Information Published in: Cognitive Computation
