description: We consider the possibility of multiply-connected spacetimes, ranging from the Flamm-Einstein-Rosen bridge, geons, and the modern renaissance of traversable wormholes. A fundamental property in wormhole physics is the flaring-out condition of the throat, which through the Einstein field equation entails the violation of the null energy condition. In the context of modified theories of gravity, it has also been shown that the normal matter can be imposed to satisfy the energy conditions, and it is the higher order curvature terms, interpreted as a gravitational fluid, that sustain these non-standard wormhole geometries, fundamentally different from their counterparts in general relativity. We explore interesting features of these geometries, in particular, the physical properties and characteristics of these `exotic spacetimes'.

description: PV system deployment across the globe has grown from 1 GWp in 2000 to ~584 GWp in 20 years, a compound annual growth rate of 38%. Although Asia has seen most of its growth in the past half-decade only, more than 50% of all PV systems are found in Asian locations today. Nonetheless, PV system behavior, either as a single unit or as fleets, is still a relatively new concept to grid operators and therefore it is important to understand what may happen at special “corner case” conditions. A solar eclipse presents such a scenario, where the drop in power with the reduced amount of sunlight reaching the Earth’s surface could present sudden negative (and positive, at the end of the eclipse) gradients of power which may bring challenges. In this work, we aim at showcasing empirical data from various PV systems and meteorological stations across India and Southeast Asia during an eclipse, so that important datasets surface on this topic. We demonstrate loss of power at these systems in relation to astronomic eclipse sun coverage figures as well as loss of energy generation for the observed phenomena across various Asian locations. We also discuss other aspects observed during the eclipse of 26 December 2019 and propose areas of study ahead.

description: Determining the prime factors of a given number N is a problem, which requires super-polynomial time for conventional digital computers. A polynomial-time algorithm was invented by P. Shor for quantum computers. However, the realization of quantum computers is associated with significant technological challenges in achieving and preserving quantum entanglement. Prime factorization can be also solved by using classical wave interference without quantum entanglement. In this work, we present experimental data showing prime factorization by utilizing spin wave interference. The prime factorization includes three major steps. First, general type computer calculates the sequence of numbers mkmod(N), where N is the number to be factorized, m is a randomly chosen positive integer, and k=0,1,2,3,4,5,6 .. . Next, the period of calculated sequence r is determined by exploiting spin wave interference. Finally, the general type computer finds the primes based on the obtained r. The experiment on the period finding was accomplished on the 6-terminal Y3Fe2(FeO4)3 device. We chose number 15 for a test and found its primes in a sequence of measurements. The obtained data demonstrate an example of solving a prime factorization problem using classical wave interference. We discuss the physical and technological limitations of this approach, which define the maximum size of N and the computational speed. Though this classical approach cannot compete with the quantum algorithm in efficiency, magnonic holographic devices can be potentially utilized as complementary logic units aimed to speed up prime factorization with classical computers.

This is an unedited, and apparently unstudied, text of considerable historical interest, not only for the Rule itself but for the extensive preface that contextualizes its formulation. Although presumably copies of this Rule were made for the houses of the Third Order Regular in sixteenth-century Spain, no other copies are documented to date. ... This Rule in Spanish for the Order of Penance, the Third Order Regular of St. Francis, was issued by Fray Antonio de Tablada, Visitor General and chief minister of the Third Order Regular in Castile, Leo?�n, and Andalusia, at the Order's General Chapter meeting of 1528. -- Seller's description.

description: Spacecraft attitude control using only magnetic torques is a periodic time-varying system as the Earth magnetic field in the spacecraft body frame changes periodically while the spacecraft circles around the Earth. The optimal controller design therefore involves the solutions of the periodic Riccati differential or algebraic equations. This paper proposes an efficient algorithm for the periodic discrete-time Riccati equation arising from a linear periodic time-varying system $(\A,\B)$, which explores and utilizes the fact that $\A$ is time-invariant and only $\B$ is time-varying in the system, a special properties associated with the problem of spacecraft attitude control using only magnetic torques.

description: In this paper, we present the key findings of a complete diagnostic study on five utility-scale PV plants of an overall 29 MW installed capacity, which were inaugurated and have been operating in France the last 7 years. The diagnostic measurements were implemented by means of drone-based aerial infrared (IR) imaging, coupled with auxiliary ground-based I-V tracing and visual inspections. On this basis, we performed detailed fault classification and power analysis, where we uncovered several early reliability issues and failures on both module and system/balanceof-system (BOS) level. Today, the majority of PV modules being decommissioned with such failures, simply enter the waste stream and are either disposed as waste (in their majority) or recycled. In our case, nearly 80% of these failures were identified as repairable, whereas the associated power losses were quantified and (where applicable) fully recovered. In such way, we also highlight importance of the sustainability perspective and, thus, of streamlined endof-life (EoL) management, in PV operations and maintenance (O&M).

description: Different data pipelines and statistical methods are applied to photovoltaic (PV) performance datasets to quantify the PV module degradation rate. Since the real value of degradation rate is unknown, a variety of unvalidated values has been reported in the literature. As such, the PV industry commonly treats this metric in an assumptive manner based on a statistically extracted range from the literature. However, the accuracy and uncertainty of degradation rate depends on a number of parameters including seasonality in respect to the local climatic conditions and also the response of a particular PV technology. In addition, the selection of data pipeline and statistical method may compound on the accuracy and uncertainty. In order to provide insights, a framework of bulk simulations of PV performance datasets using data from different climates is under development. Known degradation rates are emulated and large parametric studies are conducted in order to observe the convergence time on different PV module types based on several selection criteria such as performance metric, statistical method, etc. The preliminary results that are presented in this paper confirm that, indeed, climates and PV module types with typically lower seasonality can provide accurate degradation rate results in a shorter time period, compared to locations and PV module types that exhibit higher seasonality. As expected, the selection of data pipeline (e.g. metric, temperature correction, etc.) and statistical method also has a strong influence and therefore, introduces additional challenges.

description: Operation and maintenance (O&M) is critical for running successful PV projects as the reliable renewable resource for energy transition. We have utilized artificial intelligence (AI) system to optimize O&M task for 120 projects up to 39.2MW more than 2 years. The average daily energy yield of 3.9% (0.13 kWh/kWp) is increased for the projects with AI system, and the O&M transportation cost is 41% reduced. The power prediction algorithm of the fingerprint-like model for each inverter-MPPT is upgraded by simulated POA irradiance instead of that measured by only one pyranometer in multiple-orientation power plants. According to the one-year experiment result for 74 the projects (26.3MW) with 4,792 MPPTs, the Mean Absolute Percentage Error (MAPE) of power prediction decreases from 17.1% to 7.0%. The overall fault detection precision reaches 98.6%, while the precision of failure mode diagnosis improves from 92.3% to 94.0%. The accurate failure mode diagnosis practically enhances operation efficiency and reduces the maintenance expense in the cost structure by low carbon footprint O&M solution.

description: High voltage photovoltaic (PV) systems are affected by potential induced degradation (PID). PID detection by conventional data analysis methods could take a long time leading to unnoticed energy loss. If PID is detected at an early stage, energy loss could be avoided by taking the appropriate measures. This paper presents a new method for detecting PID at an early stage (< 1% power loss). The method is based on low current DC signals and, hence, it could be implemented in a low cost sensor. The method was tested experimentally on standard multicell crystalline silicon PV modules and successfully detected PID before 2% power loss.
CGC/saturation approach for high energy soft interactions: $\mathbf{v_2}$ in proton-proton collisions

description: In this paper we continue our program to construct a model for high energy soft interactions, based on the CGC/saturation approach. We demonstrate that in our model which describes diffractive physics as well as multi-particle production at high energy, the density variation mechanism leads to the value of $v_2$ which is about $60\% ÷70\%$ of the measured $v_2$. Bearing in mind that in CGC/saturation approach there are two other mechanisms present: Bose enhancement in the wave function and local anisotropy, we believe that the azimuthal long range rapidity correlations in proton-proton collisions stem from the CGC/saturation physics, and not from quark-gluon plasma production.

description: In this work we present the ongoing PV4.0 project, which aims to develop a cost-effective PV plant monitoring and intervention system. By linking PV plant measurement data to a digital ticketing and asset management system, and additionally including the recently developed Cost-Priority-Number method [1], a tool will be developed that applies the concepts of Industry 4.0 to the PV sector. The developed tool aims to improve O&M by prioritizing maintenance activities, and streamlining and further digitalizing the workflow of technicians. Fault detection algorithms are developed based on machine learning approaches like clustering and outlier detection to automatically detect and classify anomalies in PV system output and consequently create maintenance tickets that specify a further course of action. By applying automatic failure detection, the aim is to decrease the time required for failure detection and intervention, in order to minimize revenue losses. By analysing historical and real-time PV plant data and historical failures in operation, the potential for predictive monitoring will be investigated. The digital tools will furthermore produce valuable statistics on PV plant failure modes within each analysed PV plant, and for PV plants in general.

description: We investigate the topological degeneracy that can be realized in Abelian fractional quantum spin Hall states with multiply connected gapped boundaries. Such a topological degeneracy (also dubbed as "boundary degeneracy") does not require superconducting proximity effect and can be created by simply applying a depletion gate to the quantum spin Hall material and using a generic spin-mixing term (e.g., due to backscattering) to gap out the edge modes. We construct an exactly soluble microscopic model manifesting this topological degeneracy and solve it using the recently developed technique [S. Ganeshan and M. Levin, Phys. Rev. B 93, 075118 (2016)]. The corresponding string operators spanning this degeneracy are explicitly calculated. It is argued that the proposed scheme is experimentally reasonable.

description: We calculate the complete next-to-leading order (NLO) QCD corrections to the $T$-odd mirror quark pair ($q_-\bar q_-=u_-\bar u_-$, $c_-\bar c_-$, $d_-\bar d_-$, $s_-\bar s_-$) production in the littlest Higgs model with $T$-parity (LHT) at a high energy $γγ$ collider. We present the dependence of the leading order (LO) and NLO QCD corrected cross sections on the colliding energy $\sqrt{s}$. Our calculation includes the subsequent full weak decays of the final $T$-odd mirror quarks by adopting the narrow width approximation and the exclusive 2-jet event selection criterion. We provide the LO and QCD NLO kinematic distributions of final particles. We find that the NLO QCD correction is phase space dependent and modifies the LO cross section evidently. The $K$-factor increases noticeably when $\sqrt{s}$ approaches the threshold of the on-shell $q_-$-pair production. We conclude that it is possible to separate the signature of the $T$-odd quark pair production from possible Standard Model background by taking proper kinematic cut.

description: There is a need for continuous monitoring and evaluation of the reliability and the performance of Photovoltaic (PV) power plant inverters to secure uninterrupted power generation. The availability of operation and maintenance (O&M) documentation, and the sensor measurements in most PV power plants is very scarce. Therefore, the scope of this study is to evaluate the reliability and the performance of Photovoltaic (PV) inverters even when there are no failure history and no access to data from PV modules. The proposed method aims the diagnosis and prediction of failures using only the available information in industrial PV plants (Power, Radiation, Temperature, etc.). In order to achieve this objective, there is a need to explore appropriate data-driven methods and the correct interpretation of the findings obtained from both individual and merged models in a systematic manner. This approach allows us to cover the entire spectrum of possible variables registered in a PV plant and to perform analysis from different perspectives.

description: Cost-effective tools for on-site defect detection help to ensure the reliable power production of photovoltaic (PV) plants. On-site examination is essential to minimize PV module damage, electrical yield loss and operation disruption caused by additional transport to the laboratory (off-site examination) or disruption of the electrical circuits. Outdoor inspection may be carried out by using highly sensitive imaging techniques, such as luminescence or thermography imaging. To avoid electrical contact switching time for electroluminescence (EL), we replaced intrusive electrical excitation by non-contact excitation with light, and measured photoluminescence (PL) instead. Nowadays, luminescence is used to detect defects such as increased series resistance, local cell irregularities, shunts and electrical disconnections in solar cells and modules. Our excitation source consists of twelve broadband, white, high power (100 W electrical power), chip on board light emitting diodes (LEDs) coupled with low-cost short pass filters. The light source is suitable for InGaAs and silicon (Si) detectors and mobile outdoor applications, which makes this setup a tool for on-site PL inspections for large area modules. The PL setup presented in this paper is capable of measuring large area PV modules of up to 72 cells with one image.

description: Labour market shocks differ across countries and regions. One way the economy can adjust for adverse regional shocks to employment is by labour mobility. In this paper, we study the popula­tion response to regional labour market shocks via migration. We draw on the EU-LFS microdata in the EU-27 over the period 1995–2020 for the working-age population. The data allow us to per­form our analyses for the detailed NUTS2 level, as well as consider commuting-zones. We adopt an IV approach with an industry shift-share instrument and account for (potential) time lag in the migratory process by including an error-correction term. We find that in 10 years population movement of potential workers generally corrects for about 50% of a shock to regional employ­ment at the NUTS2 and commuting-zone level. This overall population elasticity, however, hides substantial differences in elasticities with women, individuals aged 25 to 44, foreign-born and higher educated individuals reporting higher population elasticities. In addition, our results are driven by Western European countries. The initial population response to employment shocks is insignificant in a sample of Eastern European countries. Also, the migratory response is found to be more delayed when a region is confronted with a negative shock to employment.

Trusted Research Environments

description: This report provides a guide on setting up a Secure Remote Connection between two Trusted Research Environments (TREs)1. It is based on the experiences of setting up such a connection between the UKDS SecureLab and other TREs, and most recently and specifically between the UKDS SecureLab and the Secure Data Centre at GESIS within the SSHOC project, WP5.4. It is designed to aid future setups of remote connections between TREs, a need which increasingly arises in the fast-changing secure data landscape, and a necessary step to improving the international data infrastructure to facilitate evidence- based, global, policy-relevant, impactful research. As a result of the collaborative work undertaken within the SSHOC Deliverable D5.11, for the first time, controlled2 GESIS data will be made available to researchers outside of Germany, via the GESIS access point at the UK Data Service Safe Room at the UKDA, University of Essex. Further, researchers will be able to access selected UKDS SecureLab data through GESIS’ Secure Data Center Safe Room in Cologne. Setting up a Secure Remote Connection between the UKDS SecureLab and the Secure Data Centre at GESIS within the SSHOC project faced considerable challenges due to the onset of the COVID-19 Pandemic in 2020 and its implications for the next two years. However, the goals of this deliverable were achieved in the end. Further, a staggered return to the offices and Safe Room openings are in sight and so, even though the SSHOC project itself comes to an end, work on and around the access points, generating use cases, improving workflows etc. will continue. The report describes the different areas of work, tasks, and aspects that have to be addressed and taken into consideration ahead of and during the setting up of a Secure Remote Connection between two TREs. It is anticipated that this report will provide a blueprint for setting up further remote connections. The details might differ from case to case, but the steps described here are fundamental and must be addressed when setting up a Secure Remote Connection between two TREs.

description: An updated set of (anti)neutrino-nucleon charged and neutral current cross sections at $3~{\rm GeV} \lesssim E_ν\lesssim 100~{\rm GeV}$ is presented. These cross sections are of particular interest for the detector optimization and data processing and interpretation in the future Megaton-scale experiments like PINGU, ORCA, and Hyper-Kamiokande. Finite masses of charged leptons and target mass corrections in exclusive and deep inelastic $(\barν)νN$ interactions are taken into account. A new set of QCD NNLO parton density functions, the ABMP15, is used for calculation of the DIS cross sections. The sensitivity of the cross sections to phenomenological parameters and to extrapolations of the nucleon structure functions to small $x$ and $Q^2$ is studied. An agreement within the uncertainties of our calculations with experimental data is demonstrated.

Determinants Of Supply Chain Management Performance: The Case Of Metehara Sugar Factory
Creators: name: Derbie, Tesfaye
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: Supply Chain Performance measures clearly show not only how well an institution meets the needs of its customers but also how it handles its customers in terms of quality and efficiency to add customer value for goods and services. This has triggered the need for performance measures, or metrics, for global supply chain performance improvements. Nevertheless, no study has been conducted to identify or assess the determinants of supply chain management performance in sugar factories. This study mainly tries to examine the determinants of supply chain management performance in Metehara Sugar Factory. The study problem was answered through a combination of qualitative and quantitative approach in order to reduce the limitation and an explanatory design was employed in the current study to assess the determinants of supply chain management performance. The researcher used primary and secondary data for further analysis. The study found a positive correlation among the five (supplier buyer relation, human metrics, external supply chain, environmental factor and information sharing) supply chain managements performance determinants. Furthermore, the value of regression analysis shows that supplier buyer relation, human metrics, external supply chain, environmental factor and information sharing have a statistical significant effect on supply chain management performance. All the independent variables in the study influenced supply chain performance and with the highest influence being the supplier buyer relationship and human metrics and the least being external supply chain and environment. In order to improve the supply chain management performance, the factory needs to create a long-term strategic approach.

description: A total PV capacity of over 50 MWp and over 300 000 modules has been analyzed using aerial infrared thermography combined with production data analysis. By combining the two methods, the effect of different thermal signatures on power production can be evaluated. The analysis shows a near linear trend between the number of affected module substrings and power loss. We find a slope of -0.67 ± 0.05 % per module substring affected by thermal signatures in power loss on two 24 module strings connected in parallel. Further, the IRT analysis shows that signatures related to cell and interconnect are the most numerous, corresponding to about 2/3 of the thermal signatures observed, while 1/3 are junction box related for the analyzed system. Further, the effect on yield for 5 different thermal signature categories has been evaluated through yield analysis. Our analysis shows that uniformly hot module substrings on average lead to the largest power loss, while module substrings with whole hot cell exhibit the smallest loss.

description: Using dielectric spectroscopy and differential scanning calorimetry, we have performed a detailed investigation of the influence of water uptake on the translational and reorientational glassy dynamics in the typical ionic liquid 1-Butyl-3-methyl-imidazolium chloride. From a careful analysis of the measured dielectric permittivity and conductivity spectra, we find a significant acceleration of cation reorientation and a marked increase of the ionic conductivity for higher water contents. The latter effect mainly arises due to a strong impact of water content on the glass temperature, which for the well-dried material is found to be larger than any values reported in literature for this system. The fragility, characterizing the non-Arrhenius glassy dynamics of the ionic subsystem, also changes with varying water content. Decoupling of the ionic motion from the structural dynamics has to be considered to explain the results.

description: Crack initiation and growth in rubber vulcanisates is a major problem when rubber is repeatedly stressed in service. Often, micro-cracks exist in rubber because of mold damage or dust particles which mix with rubber compound during various stages of processing. These imperfections act as crack initiation sites and when cracks grow under repeated stressing, rubber fails, causing poor performance and short service life of rubber article. In a simple term, flex life is defined to be the number of cycles to failure in a test. There are numerous factors which affect crack initiation and growth in rubber vulcanisates. Crosslink density variation and molecular structure of raw rubber can influence the flex life of rubber vulcanisates. This project firstly investigated three grades of polybutadiene rubber (BR) i.e., highly linear, linear and branched chain grades. The flex life or the number of cycles to failure was measured for each rubber vulcanisate. The results indicated that the rubber vulcanisate with highly linear chains had the longest flex life, followed by the one with linear chain and then the one with long branched chains. In above work the viscosities of different grades of Polybutadiene rubber grades were widely different, so another study in the second part of this thesis had been carried out in order to measure the flex life of rubber compounds based on similar viscosities. In a separate experiment, the crack initiation and propagation were measured. The results indicated that crack initiation covered 75% of the flex life of these rubber compounds. To correlate the strain energy involved in flex life of the rubber vulcanisate with linear chains to the rate of crack growth in the rubber, further tests were performed. The results indicated a linear relation exist between the rate of crack growth to the strain energy release rate. This correlation was subsequently used to re-define an actual flex life for the rubber vulcanizate.In the next part of thesis , Kaolin filled polybutadiene rubber compounds were manufactured, tested for various properties and lastly, Kaolin and silica filled Natural rubber and Polybutadiene rubber compounds had been prepared in order of increasing loading of fillers and tested for curing characteristics, mechanical properties, crosslinking linking, crack propagation, dynamic mechanical properties and filler dispersion by SEM and these properties correlated in order to study the effect of fillers on the properties of these rubber compounds.

description: As a result of the dramatic increase in natural and man-made disaster losses, humanitarian practitioners and academicians are seeking effective and efficient means of minimizing the tremendous losses. Although various theoretical underpinnings are beneficial to understand the importance of supply chain in a humanitarian context, the management of logistics coordination mechanism along the humanitarian supply chain has yet to be explored. This study seeks to examine the antecedents and outcomes of coordination in logistics management to mitigate the coordination challenges and enhance humanitarian logistics performance. In particular, the factors (resource sharing, information sharing and organizational relationship) are identified to evaluate their causal relationship of coordination mechanism initiatives that are presumed to influence humanitarian logistics performance concerting the moderating role of relief environmental uncertainty. Drawing on social network theory, the resource based theory and relief coordination theory, a conceptual model was developed and tested using 56 respondents working in ERCS. Based on the research finding it was recommended that ERCS to consider: mechanisms of assurance of funding by implementing partnership preconditions with donors and other stakeholders, increase the amount exchange of information with partners, improved specialization in HL management and cross-cutting tasks and forge long term collaboration and partnership with other actors to enhance performance of logistics coordination. In addition ERCS needs to establish appropriate policy, procedures and mechanisms to facilitate logistical coordination by forming strategic relationship with other actors, align logistics capability and devise ways to ensure sufficiency of donors funding for logistics infrastructure, capabilities and long term disaster preparedness. It is also stipulated that ERCS design improved standardization of operations and common guidelines and/or service requirements, invest in logistics expertise and knowledge management practice by employing continuous improvement mechanisms towards logistics coordination optimization and enhanced HL performance

description: We report detailed dc magnetization, linear and non-linear ac susceptibility measurements on the hole doped disordered cobaltite La$_{0.5}$Ba$_{0.5}$CoO$_3$. Our results show that the magnetically ordered state of the system consists of coexisting non-ferromagnetic phases along with percolating ferromagnetic-clusters. The percolating ferromagnetic-clusters possibly start a magnetic ordering at the Curie temperature of 201.5(5)~K. The non-ferromagnetic phases mainly consist of antiferromagnetic-clusters with size smaller than the ferromagnetic-clusters. Below Curie temperature the system exhibits an irreversibility in the field cooled and zero field cooled magnetization and frequency dependence in the peak of ac susceptibility. These dynamical features indicate towards the possible coexistence of spin-glass phase along with ferromagnetic-clusters similar to La$_{1-x}$Sr$_{x}$CoO$_3$ (x$\geq$0.18), but the absence of field divergence in third harmonic of ac susceptibility and zero field cooled memory clearly rule out any such possibility. We argue that the spin-glass phase in La$_{1-x}$Sr$_{x}$CoO$_3$ (x$\geq$0.18) is associated with the presence of incommensurate antiferromagnetic ordering in non-ferromagnetic phases which is absent in La$_{0.5}$Ba$_{0.5}$CoO$_3$. Our analysis show that the observed dynamical features in La$_{0.5}$Ba$_{0.5}$CoO$_3$ are possibly due to progressive thermal blocking of ferromagnetic-clusters which is further confirmed by the Wohlfarth's model of superparamagnetism. The frequency dependence of the peak of ac susceptibility obeys the Vogel-Fulcher law with $τ_0\approx10^{-9}$s. This together with the existence of an AT line in H-T space indicates the presence of significant inter-cluster interaction among these ferromagnetic-clusters.

description: We discuss the superfluid properties of a Bose-Einstein condensed gas with spin-orbit coupling, recently realized in experiments. We find a finite normal fluid density $ρ_n$ at zero temperature which turns out to be a function of the Raman coupling. In particular, the entire fluid becomes normal at the transition point from the zero momentum to the plane wave phase, even though the condensate fraction remains finite. We emphasize the crucial role played by the gapped branch of the elementary excitations and discuss its contributions to various sum rules. Finally, we prove that an independent definition of superfluid density $ρ_s$, using the phase twist method, satisfies the equality $ρ_n+ρ_s=ρ$, the total density, despite the breaking of Galilean invariance.

description: Electroluminescence images have been used to qualify the performance of PV modules. Yet, to assess the status and techno-economic performance of a module in a string, quantitative information is required. In this work, we propose a method to predict PV module IV curves from electroluminescence images using a deep learning algorithm. The proposed method consists of creating eleven deep learning models that predict ten points on the IV curve, including ISC, Impp, Vmpp and VOC. We test this method on a dataset of 574 electroluminescence images and IV curves with one dominant fault: inactive cell areas. Results show that the deep learning models are able to find a relationship between the inactive areas of the PV module electroluminescence image and the PV module IV curve. For the test dataset, we predict IV curves with good accuracy values and a mean absolute error for module power below 5 W.
