description: Floating Photovoltaics (FPV) is a Photovoltaic (PV) based energy generation approach on water surfaces, to mitigate the solar energy high land-use footprint issue. Since 2007, the technology and industry have come a long way with a cumulative installed capacity of 1.9 GWp by 2019. This article has studied and analyzed the current status and future directions of this technology with a SWOT analysis, by reviewing scientific articles and industrial reports. Additionally, technology evolutions are addressed such as moving FPV structures from man-made still-water reservoirs to near- and offshore open seas. The technology is gaining popularity due to its potentials such as resolving green energy land usage footprint, energy security, local geographically-free energy generation, innovative business models enabler, fast deployment, and providing a solution to socio-political and community acceptance issues. Additionally, the technology has extreme potentials to meet global electricity demand by only utilizing 51.5% of the global man-made reservoirs (excluding huge potentials of near-shore and offshore applications). Finally challenges and mitigation for topics such as lack of good practices and standards for material choice due to immature technology, possible fresh water source contamination and effects on eco-system are discussed. However, these are rapidly changing as the technology and industry matures.

description: Tourism is today considered as a crucial employment sector in many developing countries. In the growing field of historical tourism research, however, the relationships between tourism and development, and the role of international organizations, above all the UN, have been given little attention to date. My paper will illuminate how during the 1960s tourism first became the subject of UN policies and a praised solution for developing countries. Examples from expert consultancy missions in developing countries such as Ethiopia, India and Nepal will be contextualized within the more general debates and programme activities for heritage conservation and also the first UN development decade. Drawing on sources from the archives of UNESCO, as well as tourism promotion material, it will be possible to understand how tourism sectors in many so-called developing countries were shaped considerably by this international cooperation. Like in other areas of development aid, activities in tourism were grounded in scientific studies and based on statistical data and analysis by international experts. Examining this knowledge production is a telling exercise in understanding development histories colonial legacies under the umbrella of the UN during the 1960s and 1970s.

description: PV carports are an ideal solution to produce electricity locally and sustainably, while taking advantage of the dual use of the space. On average, large carports have a power output of 0.17 kWp/m2. The average costs amount to 2'100 CHF/kWp. The price per kWp decreases slightly when the power clearly increases. The costs of the PV modules are lower than the costs for the carport's foundation and supporting structure, which represent generally between 30 % and 60 % of the total costs. The amount of steel is estimated to 155 kg/kWp and the quantity of concrete required is approximately 650 kg/kWp. The specificities of the terrain naturally have an impact on these values. A carport parking space emits 690 kgCO2-eq during the construction phase and an electric vehicle (EV) 11.2 kg-Co2-eq/100 km on average. Innovative projects include retractable roofs to offers the potential to reduce the amount of material used in the mounting structure, due to storing the PV modules in a safety box during heavy wind or snow load. The use of wood instead of metal, and screws anchor instead of concrete, as well as the addition of greenery, greatly reduces total CO2 emissions.

description: The neutron-rich nucleus $^{144}$Ba ($t_{1/2}$=11.5 s) is expected to exhibit some of the strongest octupole correlations among nuclei with mass numbers $A$ less than 200. Until now, indirect evidence for such strong correlations has been inferred from observations such as enhanced $E1$ transitions and interleaving positive- and negative-parity levels in the ground-state band. In this experiment, the octupole strength was measured directly by sub-barrier, multi-step Coulomb excitation of a post-accelerated 650-MeV $^{144}$Ba beam on a 1.0-mg/cm$^2$ $^{208}$Pb target. The measured value of the matrix element, $\langle 3_1^- \| \mathcal{M}(E3) \| 0_1^+ \rangle=0.65(^{+17}_{-23})$ $e$b$^{3/2}$, corresponds to a reduced $B(E3)$ transition probability of 48($^{+25}_{-34}$) W.u. This result represents an unambiguous determination of the octupole collectivity, is larger than any available theoretical prediction, and is consistent with octupole deformation.

description: The paper presents state of the art of design criteria for façade integrated photovoltaics (FIPV). A comprehensive literature review was conducted based on a large number of English-language journal papers, conference proceedings and scientific reports, mainly from recent 10 years. The study showed that there is an obvious lack of study on design criteria specific for façade integrated photovoltaics. Current design criteria for building façade integrated photovoltaics (BIPV) were analyzed and categorized according to the scale: building level and urban context. In the building level, the AIQ-model and criteria from the project IEA SHC T.41.A.2 provide the most applicable set of criteria. In the urban scope, LESO-QVS method is one of the most advanced methods for application in current stage. It is necessary to develop systematic design criteria covering both building and urban level for façade integrated PVs. Besides, criteria should take into consideration opinions from many groups involving in developing and use of buildings, i.e. architects, authorities and also end-users. Furthermore, a corresponding application tool with rating or evaluation system should be developed for the design criteria system.

description: Competition is no longer between organizations, but among supply chains. Effective supply chain management provides opportunities to create sustainable competitive advantage and enhance the competitive position of business firms. This paper attempts to study the impact of supply chain management practices on competitive position of Sesame Seed Exporter Members of Ethiopia Commodity Exchange (ECX). This research conceptualizes and develops four dimensions of SCM practice (internal and external success factors, strategic buyers' partnership, customer relationship, and information communication) and tests the relationships between SCM practices and competitive position. The data for the study was collected from 78 middle/senior management staff of the exporter firms who are familiar with the corporate strategies and supply chain operations of their companies. The relationships proposed in the framework were tested using Kendall's tau correlation, and the causal relations were analyzed using one-way ANOVA. The results show that efforts in: (1) implementing the right internal and external success factors, (2) enhancing buyers' partnership, (3) effective Information communication and (4) improving Customer Relationship have significant impact on the competitive position of the exporter firms.

description: The building and construction sector does need to contribute in a more substantial way to worldwide endeavours to become climate-neutral in 2050. Solar integration in the building envelope still represents a niche market. Furthermore, necessary CO2 reductions in the building sector cannot be achieved through PV roof installation alone. A recent study showed that building facades offering a so far untapped potential for the integration of photovoltaics [1]. The aim of the project is the development of an architecturally sophisticated exposed concrete facade with integrated, yieldoptimized smaller sized PV modules. Design and orientation of the combined building units, concrete element and photovoltaics modules in the facade will be already optimized in the digital design process by means of Algorithms-aided Design, in which facade and architectural parameters as well as technical and economic target parameters are included and thus design variants are generated. Within this paper we will present first results of the project, the developed design and technical approaches to combine concrete and photovoltaic processes and we propose, how the building sector can contribute with modular, scalable energy facades.

description: Polarization of both beams at a future Linear Collider would be ideal for facing both expected and unforeseen challenges in searches for new physics: fixing the chirality of the couplings and enabling the higher precision for the polarization meas urement itself as well as for polarization-dependent observables, it provides a powerful tool for studying new physics at the future Linear Collider, such as discovering new particles, analyzing signals model-independently and resolving precisely the unde rlying model. Techniques and engineering designs for a polarized-positron source are well advanced. Potential constraints concerning luminosity, commissioning and operating issues appear to be under control. This article mainly treats with the impact of p olarized beams on physics beyond the Standard Model, whereas the fundamentals in polarization as well as the gain in electroweak precision physics are summarized in the corresponding part I [1].

description: La$_{0.7}$Sr$_{0.3}$MnO$_3$ polycrystalline samples have been prepared using different synthesis routes. X-ray Diffraction (XRD) confirms that the samples are of single phase with R$\bar{3}$c space group. The surface morphology and particle size has been measured using Field Emission Scanning Electron Microscopy (FESEM). Magnetic measurement shows that the magnetization in the materials are affected by low crystallite size which destroys the spin ordering due to strain at grain boundaries and in turn also lead to reduction in magnetization as well as an enhanced coercivity in the material.

description: While narrow absorption lines (NALs) are relatively stable, broad absorption lines (BALs) and mini-BAL systems usually show violent time variability within a few years via a mechanism that is not yet understood. In this study, we examine variable ionization state (VIS) scenario as a plausible mechanism, as previously suspected. Over three years, we performed photometric monitoring observations of four mini-BAL and five NAL quasars at $z_{\rm em}$ $\sim$ 2.0 - 3.1 using the 105 cm Kiso Schmidt Telescope in $u$, $g$, and $i$-bands. We also performed spectroscopic monitoring observation of one of our mini-BAL quasar (HS1603+3820) using the 188-cm Okayama Telescope over the same period as the photometric observations. Our main results are as follows: (1) Structure function (SF) analysis revealed that the quasar UV flux variability over three years was not large enough to support the VIS scenario, unless the ionization condition of outflow gas is very low. (2) There was no crucial difference between the SFs of mini-BAL and NAL quasars. (3) The variability of the mini-BAL and quasar light curves was weakly synchronized with a small time delay for HS1603+3820. These results suggest that the VIS scenario may need additional mechanisms such as a variable shielding by X-ray warm absorbers.

description: There is a growing demand to utilize building façade areas for installing photovoltaics (PVs) and producing more clean energy. To support the façade integration of PVs in the urban context, this study proposed a series of evaluation criteria from an environmental aesthetic perspective. Fundamental environmental aesthetic theories were reviewed and Canter’s ‘sense of place’ theory, Kaplan’s cognitive preference model and Nasar’s six positive qualities in built environment were selected as theoretical reference for this study. In addition, a literature search including aesthetic studies for building integrated PVs and solar systems was conducted. Based on the findings, relevant aesthetic factors were grouped in two levels (i.e. urban context level and building façade level). A set of new aesthetic evaluation criteria is proposed for both levels, covering both perceived physical aspects and conceptual aspects. Colour, surface texture and glossiness are suggested as key factors for further investigation.

description: The Be-Smart project aims to contribute significantly to the strengthening of the European industrial sector in the field of solar energy and to present and demonstrate new concepts of low- cost photovoltaic (PV) products for building integration (BIPV) with a high quality architectural design (transparency, color…) named Energy positive Glasses or EpoGs. For a relevant choice of these products installation configuration, an experimental study of the impact of various parameters (see IEC TS 63126 standard) on the temperature of photovoltaic glass-glass monocrystalline silicon mini-modules is being performed for nearly one year on five different sites. A comparative analysis of first results obtained at the CEA INES site and the CEA Cadarache site is presented focusing on their maximum and their 98th percentile temperatures from December 2020 to May 2021. This most representative temperature should be considered to define EpoGs installation configuration per site. For facade integration, in cold period, the glass layers thickness seems to have an influence on photovoltaic modules temperature. As further studies, data measured in warm period will be analyzed. Then, in order to consider edges effect, similar tests will be performed on large PV modules integrated to a facade at the CEA INES site.

description: The increase in energy consumption in homes has never been as intense as in the last decade. The international alarm has resulted in various plans and strategies. This research supports the implementation of Building Integrated Photovoltaics (BIPV) which produce energy at a lower cost to the environment than traditional fuel. Also, it generates energy where it is needed, so its implementation preserves the planet's health. This research proposes a model to predict vertical PV production from vertical solar irradiation and ambient temperature measures. The predictor is an Artificial Neural Network (ANN), trained using the Levenberg-Marquardt algorithm. The research tested and compared several architectures to obtain the most accurate ANN. The one chosen was an artificial neural network with a single hidden layer. Its entry has two neurons, ambient temperature and global vertical irradiation (RaGV). This research shows that ambient Temperature and RaGV are enough to estimate BIPV production, being RaGV the most relevant variable. The introduction as input of the model of the ambient temperature increased its performance. The obtained model has good statistical results and allows to estimate the PV production of commercial panels.

description: We investigate limit models resulting from a dimensional analysis of quite general heterogeneous catalysismodels with fast sorption (i.e. exchange of mass between the bulk phase and the catalytic surface of a reactor) and fast surface chemistry for a prototypical chemical reactor. For the resulting reaction–diffusion systems with linear boundary conditions on the normalmass fluxes, but at the same time nonlinear boundary conditions on the concentrations itself, we provide analytic properties such as local-in-time well-posedness, positivity, a priori bounds and comment on steps towards global existence of strong solutions in the class W(^1,2)_p (J × Ω;R^N ), and of classical solutions in the Hölder class C(^1+α,2+2α)(J × Ω;R^N ). Exploiting that the model is based on thermodynamic principles, we further show a priori bounds related to mass conservation and the entropy principle.

description: A photovoltaic installation is subject to many constraints (such as weather conditions, shocks or dust) that can result in its ageing (such as delamination, discoloration or mould) and thus to performance losses. Only few measured data are available for an accurate long-term prediction of the performance of photovoltaic modules connected in series or building integrated. Some methods permitting to evaluate the impact of each kind of degradation on a photovoltaic field electrical production were proposed and compared. They were applied to a rooftop BIPV system based on its performance ratio and its degradation rate. A performance diagnosis of this installation was also proposed. Compared to the state of art which indicates a degradation rate between 0.5 and 0.8%/year for a rack mounted photovoltaic module, the BIPV system studied had a degradation rate of nearly 4%/year. The majority of the defects detected seems to be related to electrical issue, in particular at the level of the interconnection between the photovoltaic cells and of the bypass diodes in the electrical system. As further steps, a subprogram permitting to determine the evolution over time of the production of a BIPV system will be developed considering different types of installation and photovoltaic technologies.

description: Photovoltaic (PV) modules have traditionally been installed on roofs. In winter, fog and snow on PV modules may cause electricity losses on roof-top PV installations. Technology for snow removal is available, but there are no simple solutions. To reduce PV electricity losses on roof-top installations due to snow, PV modules should rather be mounted on vertical infrastructure (e.g., façades including balcony balustrades). While such vertical PV surfaces may offer less energy yield production over the year, they can significantly contribute to winter PV electricity in the northern (and southern) hemisphere mid-latitudes. Because of the static requirements, special PV modules are needed on façades. All façades of a building can be covered with PV modules. In contrast to PV façades, PV on windows is the one vertical element on buildings that has not been widely addressed yet by the PV industry. Yet, given the worldwide increase in glass façades, PV windows are hugely relevant. However, a window cannot be fully covered with PV, as this would obstruct its transparency. For the lengthy periods of time when transparency is not necessary, the invention of “solar blinds” are an innovative technology to harvest solar energy on vertical façades.

description: We introduce an equilibrium asset pricing model, which we build on the relationship between a novel risk measure, the Expected Downside Risk (EDR) and the expected return. On the one hand, our proposed risk measure uses a nonparametric approach that allows us to get rid of any assumption on the distribution of returns. On the other hand, our asset pricing model is based on loss-averse investors of Prospect Theory, through which we implement the risk-seeking behaviour of investors in a dynamic setting. By including EDR in our proposed model unrealistic assumptions of commonly used equilibrium models - such as the exclusion of risk-seeking or price-maker investors and the assumption of unlimited leverage opportunity for a unique interest rate - can be omitted. Therefore, we argue that based on more realistic assumptions our model is able to describe equilibrium expected returns with higher accuracy, which we support by empirical evidence as well.

description: The two residential buildings in Männedorf, Switzerland, have photovoltaic modules integrated on facades and roofs that produce renewable energy to achieve a CO2 neutral operations goal. Sunage SA, a Swiss company leader in the design, development and production of photovoltaic modules created SUNCOL, a revolutionary BIPV technology relying on fully customisable colours and materials which perfectly integrates into any facade and roof of the building. The SUNCOL BIPV can be used as traditional construction material able to generate an environmentally sound building which has an aesthetically added value. SUNCOL presents five key characteristics: colours, finishings, design, dimension, applications. The future oriented project that features the SUNCOL red-brown BIPV modules has the first fully integrated photovoltaic facade for weather protection and energy generation in monocrystalline technology with a long service life. The Männedorf project was awarded with the Watt d’Or 2021 in the Buildings and Space category by the Swiss Federal Office of Energy for the ecological and economic impact of the project.

description: In this work, we consider a noncommutative (NC) massless scalar field coupled to the classical nonrotational BTZ geometry. In a manner of the theories where the gravity emerges from the underlying scalar field theory, we study the effective action and the entropy derived from this noncommutative model. In particular, the entropy is calculated by making use of the two different approaches, the brick wall method and the heat kernel method designed for spaces with conical singularity. We show that the UV divergent structures of the entropy, obtained through these two different methods, agree with each other. It is also shown that the same renormalization condition that removes the infinities from the effective action can also be used to renormalize the entanglement entropy for the same system. Besides, the interesting feature of the NC model considered here is that it allows an interpretation in terms of an equivalent system comprising of a commutative massive scalar field, but in a modified geometry; that of the rotational BTZ black hole, the result that hints at a duality between the commutative and noncommutative systems in the background of a BTZ black hole.

Mathematical methods based in statistics, self-organized maps and neural networks reach the best results in these designs but there exists the problem that configuration of these methods is not an easy work due the high number of parameters that have to be measured. In this work we extend an algorithm for computing implications between attributes with positive and negative values for obtaining the mixed concepts lattice and also we propose a theoretical method based in these results for engine simulators adjusting specific and different elements for obtaining optimal engine configurations.

description: About a billion people survive without electricity. Even more suffer from an unreliable, poor-quality electricity supply. Most of these people live in access challenged, isolated hamlets of the Global South. Education and healthcare suffer due to the absence of adequate electricity. Extending electricity to these settlements remains a challenge. The supply-driven electricity grid in many of these places has expanded at a rate that is below the population growth, leaving an increasingly large population in darkness. Refugee settlements suffer even more. Inadequate access to cooking fuel leads to starvation. Lack of adequate illumination after dusk gives rise to frequent security issues and intensified gender violence. However, recent technological advances allow consumer engagement. A meaningful collaboration could help in sharing available resources. Embracing advances, a favorable energy access tier may be enjoyed as compared to what the supply is capable of delivering with modest investment. This work studies how consumers can benefit with collaboration; also whether the resilience assessment can influence energy access level and cost of delivered energy in refugee camps. It may be worthwhile to note that consumers not only stand to benefit from collaborative use of essential gadgets, they can gain access and affordability with situationresponsive resilience assessment.

description: The Inverse Lambertian Irradiation Method (ILIM) was developed to get the angle-resolved optical efficiency of a PV solar concentrator quickly and with a relatively simple apparatus. ILIM reverses the path of rays (reverse mode), replacing the PV receiver by a Lambertian light source and projecting the light emitted from the inlet aperture onto a far screen. When ILIM is simulated, the reverse light is projected on an absorbing hemispherical screen in order to get the map of emitted radiance. This map reproduces, apart from a constant factor, that of the optical efficiency of the concentrator operating in direct mode under collimated light. The idea behind the present work is to apply the ILIM to an urban heat island model, to get the collection efficiency of solar radiation of a receiver (a PV or thermal module, a window, etc.) in presence of a strong optical interaction with the urban environment. The receiver is then transformed into a Lambertian source and the light diffused, after the interaction with the surrounding environment (the ground, the buildings walls, any green elements, etc.), is projected onto the absorbing hemispherical dome. The absorbed irradiance, once transformed into a map of radiance, gives the map of collection efficiency. This map, when associated with the path of Sun, gives the actual power (or luminous flux) collected by the receiver, once the incident irradiance (or illuminance) as a function of the Sun position is known.

description: The establishment of distributed energy generation through residential and commercial PV applications creates new energy markets where the traditional separation between energy producer and consumer is obliterated, giving rise to the new role of energy prosumer. Blockchain technology provides energy, consumers, prosumers and utilities with a novel, secure and cost effective energy-trading solution through the automation of direct energy transactions within a distributed database architecture rooted in cryptographic hashing and consensus-based verification. The target of this study is illustrating the forecasted households' s power profiles as well as operation of any blockchain process and apply a generic ABM simulation framework for electricity exchange (see Figure. 1). An original version of a resilient multi agent structure for a Transactive Energy (TE) type of Distributed Energy Resources (DER) within the ECCH microgrid dependent on blockchain engineering was designed & simulated. Recently proposed blockchain-based LEMs use auction designs to match future demand and supply. Thus, such blockchain-based LEMs rely on accurate short-term forecasts of individual households’ energy consumption and production. Often, such accurate forecasts are simply assumed to be given. The present research tested this assumption by first evaluating the forecast accuracy achievable with state-of-the-art energy forecasting techniques for individual households and then, assessing the effect of prediction errors on market outcomes in three different supply scenarios. The evaluation showed that, although a LSTM model is capable of achieving reasonably low forecasting errors. The prediction process will be fitted to the setup of a blockchain-based LEM. Therefore, the current analysis distinguishes itself notably out of prior experiments which entirely attempt to forecast smart meter time sequence generally.

description: The high tunability of the density of states of graphene makes it an ideal probe of quantum transport in different regimes. In particular, the supercurrent that can flow through a non-superconducting (N) material connected to two superconducting electrodes, crucially depends on the lenghth of the N relative to the superconducting coherence length. Using graphene as the N material we have investigated the full range of the superconducting proximity effect, from short to long diffusive junctions. By combining several S/graphene/S samples with different contacts and lengths, and measuring their gate-dependent critical currents ($ I_c $) and normal state resistance $ R_N $, we compare the product $eR_NI_c$ to the relevant energies, the Thouless energy in long junctions and the superconducting gap of the contacts in short junctions, over three orders of magnitude of Thouless energy. The experimental variations strikingly follow a universal law, close to the predictions of the proximity effect both in the long and short junction regime, as well as in the crossover region, thereby revealing the interplay of the different energy scales. Differences in the numerical coefficients reveal the crucial role played by the interfacial barrier between graphene and the superconducting electrodes, which reduces the supercurrent in both short and long junctions. Surprisingly the reduction of supercurrent is independent of the gate voltage and of the nature of the electrodes. A reduced induced gap and Thouless energy are extracted, revealing the role played by the dwell time in the barrier in the short junction, and an effective increased diffusion time in the long junction. We compare our results to the theoretical predictions of Usadel equations and numerical simulations which better reproduce experiments with imperfect NS interfaces.

description: With its growing population and industrialization, DREs, and solar technologies in particular, provide a sustainable means of bridging the current energy deficit in Africa, increasing supply reliability and meeting future demand. Data acquisition and data management systems allow real time monitoring and control of energy systems as well as performance analysis. However commercial data acquisition systems often have cost implications that are prohibitive for small PV systems and installations in developing countries. In this paper, a multi-user, multi-purpose microgrid database system is designed and implemented. MAVOWATT 270 power quality analyzers by GOSSEN METRAWATT, raspberry pi modules and sensors are used for measuring, recording and storing electrical and meteorological data in East Africa. Socio-economic data is also stored in the database. The designed system employs open source software and hardware solutions which are best suited to developing regions like East Africa due to the lower cost implications. The expected results promise a comprehensive database covering different electro-technical and socio-economic parameters useful for optimal design of microgrid systems.

description: SERENDI-PV project is addressing some of the main concerns which would enable the increase in the penetration of PV generated power on to the European grids. On the one hand the project will address a reduction of the parameters which have the strongest influence on the risk perception for new investments in the sector in order to reduce the Levelized Cost of Energy, mainly associated with the new PV technologies such as bifacial, floating PV and building integrated PV: modelling (better energy yield assessments), faults diagnostics (increase the performance of PV systems), in-field quality control (better reliability), and forecasting. Special focus will be paid on issues that may occur to the PV plants, such as soiling (dust), snow and degradation over the years. On the other hand, the technical challenges and opportunities that will come with the increase of the penetration in the grids, such as the potential of PV to offer ancillary services, etc. will be assessed. Short-term forecasting and nowcasting fleets of distributed PV systems as a whole (aggregation) instead of PV systems alone will also play a key role in higher PV penetration and will be investigated in the project.

description: Genetic algorithms are stochastic iterative algorithms in which a population of individuals evolve by emulating the process of biological evolution and natural selection. The R package GA provides a collection of general purpose functions for optimisation using genetic algorithms. This paper describes some enhancements recently introduced in version 3 of the package. In particular, hybrid GAs have been implemented by including the option to perform local searches during the evolution. This allows to combine the power of genetic algorithms with the speed of a local optimiser. Another major improvement is the provision of facilities for parallel computing. Parallelisation has been implemented using both the master-slave approach and the islands evolution model. Several examples of usage are presented, with both real-world data examples and benchmark functions, showing that often high-quality solutions can be obtained more efficiently.
