description: In theory, building automation and management systems (BAMSs) can provide all the components and functionalities required for analyzing and operating buildings. However, in reality, these systems can only ensure the control of heating ventilation and air conditioning system systems. Therefore, many other tasks are left to the operator, e.g. evaluating buildings’ performance, detecting abnormal energy consumption, identifying the changes needed to improve efficiency, ensuring the security and privacy of end-users, etc. To that end, there has been a movement for developing artificial intelligence (AI) big data analytic tools as they offer various new and tailor-made solutions that are incredibly appropriate for practical buildings’ management. Typically, they can help the operator in (i) analyzing the tons of connected equipment data; and; (ii) making intelligent, efficient, and on-time decisions to improve the buildings’ performance. This paper presents a comprehensive systematic survey on using AI-big data analytics in BAMSs. It covers various AI-based tasks, e.g. load forecasting, water management, indoor environmental quality monitoring, occupancy detection, etc. The first part of this paper adopts a well-designed taxonomy to overview existing frameworks. A comprehensive review is conducted about different aspects, including the learning process, building environment, computing platforms, and application scenario. Moving on, a critical discussion is performed to identify current challenges. The second part aims at providing the reader with insights into the real-world application of AI-big data analytics. Thus, three case studies that demonstrate the use of AI-big data analytics in BAMSs are presented, focusing on energy anomaly detection in residential and office buildings and energy and performance optimization in sports facilities. Lastly, future directions and valuable recommendations are identified to improve the performance and reliability of BAMSs in intelligent buildings.Other Information Published in: Artificial Intelligence Review

description: This work is dedicated to separating volume recombination from surface recombination in crystalline
silicon solar cells and wafers by exploiting reabsorption of luminescence. Due to reabsorption, the local steady state
excess charge carrier depth distribution – which contains information about local recombination properties – affects
the luminescence spectrum emitted by a device. This depth distribution can be determined by comparing images
acquired with several optical short pass filters to a model based on the continuity equation. An algorithm which
yields good results for both electroluminescence on silicon solar cells as well as photoluminescence on silicon wafers
is introduced and discussed.

description: Objectives To compare between 3 archwires (AWs) for leveling curve of Spee (COS) in terms of efficacy of reduction, external apical root resorption (EARR), pain experienced, and the lower arch dimensional changes during COS leveling. Trial design Randomized clinical trial. Setting Jordan University of Science and Technology Postgraduate dental clinics. Material and methods Fifty-three subjects with COS > 5 mm were included in this study. The subjects were randomly divided into three groups based on the AW used: group 1, 0.017 × 0.025-inch stainless-steel (SS) AW; group 2, 0.019 × 0.025-inch SS AW; and group 3, 0.021 × 0.025-inch β-titanium (TMA) AW. The intervention was randomly allocated using the permuted random block size of 3 with a 1:1:1 allocation ratio. In the three groups, a 5-mm depth reverse COS was placed in the AWs. The following time points were defined for COS assessment: T1, before interventional leveling AW placement; and T2–T7, 1–6 months after interventional leveling AW placement. Records consisted of dental study models and periapical (PA) radiographs. Pain scores were recorded using visual analogue scale. Patients were followed up on a monthly basis until COS < 1.5 mm. Main outcome measures COS depth reduction, lower incisors’ EARR, pain scores, and arch dimensional changes. Results An overall reduction of 3.82 mm, 4.47 mm, and 3.85 mm of the depth of COS was achieved in groups 1, 2, and 3, respectively. The mean differences of 0.65 mm between groups 1 and 2 and 0.62 mm between groups 2 and 3 were significant at P < 0.05. Lower incisors’ EARR during leveling COS ranged from 0.68 to 0.72 mm, from 0.63 to 0.82 mm, and from 0.53 to 0.88 mm in groups 1, 2, and 3, respectively (P > 0.05). Higher pain scores were reported by group 2 subjects during the first 24 h. Arch length and width increased significantly in groups 2 and 3 (P < 0.05). In all groups, COS leveling was achieved by lower incisor intrusion and proclination and lower molar extrusion. Conclusions All investigated AWs were effective in leveling COS with minimal lower incisors’ EARR (< 1 mm). COS was leveled by lower incisors’ intrusion and proclination and lower molar extrusion. Pain scores were the highest in group 2 during the first 24 h. Clinical relevance The 3 investigated leveling AWs were effective for the leveling COS and at the same time safe on the roots of the lower anterior teeth.Other Information Published in: Clinical Oral Investigations

description: We address the role of the phase-insensitive trusted preparation and detection noise in the security of a continuous-variable quantum key distribution, considering the Gaussian protocols on the basis of coherent and squeezed states and studying them in the conditions of Gaussian lossy and noisy channels. The influence of such a noise on the security of Gaussian quantum cryptography can be crucial, even despite the fact that a noise is trusted, due to a strongly nonlinear behavior of the quantum entropies involved in the security analysis. We recapitulate the known effect of the preparation noise in both direct and reverse-reconciliation protocols, as well as the detection noise in the reverse-reconciliation scenario. As a new result, we show the negative role of the trusted detection noise in the direct-reconciliation scheme. We also describe the role of the trusted preparation or detection noise added at the reference side of the protocols in improving the robustness of the protocols to the channel noise, confirming the positive effect for the coherent-state reverse-reconciliation protocol. Finally, we address the combined effect of trusted noise added both in the source and the detector.

description: Background Combined ipsilateral femoral neck and shaft fractures are rare and present a challenging management dilemma. This study aims to assess the outcome of concomitant fixation of the ipsilateral femoral neck and shaft fracture using single versus dual surgical implants. Methods A single-center retrospective analysis of patients who underwent fixation of ipsilateral femoral neck and shaft fractures was performed over a 13-year period. Different techniques were employed to fix the complex injury. Both the reduction and the union time were assessed radiographically. Results A total of 36 patients with ipsilateral femoral neck and shaft fractures were retrospectively identified and included in the study. Twenty-four patients (66.6%) were managed with a single cephalomedullary nail, while the remaining cases were treated with two devices. All cases were operated on within an average of 3.7 ± 7.1 days. Eight patients (22.2%) developed postoperative complications. The average follow-up period was 7.3 ± 6.8 months. Although there was no statistically significant difference between the two groups, the femoral neck fractures showed shorter union time in patients treated with one implant compared to patients treated with two implants (3.0 ± 2.3 months vs. 4.2 ± 2.6 months). Another observation was that higher percentages of implant removal/failure and malunion/nonunion were seen in patients who had one implant compared to the two implants group (12.5% vs. 8.3%). Conclusion Early surgical fixation of both fractures is associated with good outcome results. No difference in outcome was observed between both groups.Other Information Published in: European Journal of Orthopaedic Surgery & Traumatology

description: Aluminium-copper alloys of the 2xxx type receive their excellent mechanical properties by the formation of copper-rich precipitates during hardening. Size, distribution and crystal structure of the formed precipitates determine the final strength of those alloys. Adding traces of certain elements, which bind to vacancies, significantly influences the decomposition behaviour, i.e. the diffusion of the copper atoms. For high-purity ternary alloys (Al-1.7 at.% Cu-X), we investigate the interaction of copper and trace element atoms (X=In, Sn, and Pb) with quenched-in vacancies by Positron Annihilation Lifetime Spectroscopy (PALS). By employing Vickers microhardness, Differential Scanning Calorimetry (DSC) and Small Angle X-Ray Scattering (SAXS) we obtain a comprehensive picture of the decomposition process: opposite to predicted binding energies to vacancies by ab-initio calculations we find during ageing at room and elevated temperature a more retarded clustering of copper in the presence of In rather than for Sn additions, while Pb, having the highest predicted binding to vacancies, shows nearly no retarding effect compared to pure Al-Cu. If the latter would be due to a limited solubility of lead, it had to be below 2 ppm. Transmission Electron Microscopy (TEM) as imaging method complements our findings. Annealing the quenched Al-1.7 at.% Cu-X-alloys containing 100 ppm In or Sn at 150∘C leads to finely distributed θ′-precipitates on the nanoscale, since due to the trace additions the formation temperature of θ′ is lowered by more than 100∘C. According to TEM small agglomerates of trace elements (In, Sn) may support the early nucleation for the θ′-precipitates.

description: The concentrator photovoltaic (CPV) system using high efficiency triple junction cells made of - semiconductor materials, which is one of the high concentration photovoltaic power generation systems, is a promising technology expected
to provide a solution to the problem of silicon shortages we are now facing. Since the CPV system is mainly designed for use under harsh hot environmental conditions such as tropical zones around the equator and deserts, more highly reliable glass that can endure long daylight hours is needed for the system. Using our original time-tested, state-of-the-art glass forming technology, Isuzu Glass develops and manufactures collective lenses, which are indispensable to the high concentration photovoltaic power generation system. Our technology makes it possible to form a variety of glass configurations, which cannot be achieved by polishing techniques alone, flexibly
according to customers’ needs.

description: The presented study is a detailed assessment of the value of Photovoltaic (PV) energy within the German energy supply structure under consideration of the special attributes of PV: its correlation with actual consumption and local power generation. Contrary to previous statistical approaches a new dynamic approach was developed in this study. The dynamic behaviour of the PV power generation is modelled as a one-year time series. A comparison with the time series of the power demand allows assessing the value of PV energy. The value of PV
energy mainly results from its ability to substitute conventional power generation and the benefit of this kind of decentralized power generation for network stability and quality. An evaluation of these aspects is carried out for the year 2005 and a scenario in 2015.

description: Photovoltaic (PV) concentrators use lenses or mirrors to concentrate sunlight onto PV cells. This allows for a reduction in the cell area required for producing a given amount of power and also provides the opportunity to use higher performance PV cells which would be extremely expensive without concentration. This paper presents the fundamentals and preliminary results of an optical concentrator system of adjustable, very high geometrical concentration ratio (CR) composed of a combination of a total internal reflection (TIR) lens and a couple of conventional collimation lenses as Primary and Secondary Optical Elements (OE). A TIR lens and conventional lenses are combined to achieve i) very high concentration both for obtaining maximum cell efficiency and for compensation of material losses and ii) a compact design, much smaller than conventional mirror-based and Fresnel systems. TIR lens also provides a very good light profile and illumination uniformity. Also, geometrical parameters can be optimized for specific cell features.

description: This study aims to assess the effects of inhaled nitric oxide (iNO) on oxygenation in the management of pulmonary hypertension (PH) secondary to arteriovenous malformations (AVMs) in neonates. This is a matched retrospective cohort study from January 1, 2013, to December 31, 2017. The European inhaled nitric oxide registry from 43 neonatal and pediatric ICUs in 13 countries across Europe was used to extract data. The target population was neonates treated with iNO for the management of PH. The cases (PH secondary to AVMs treated with iNO) were matched (1:4 ratio) to controls (PH without AVMs treated with iNO). The main outcome measure was the absolute change of oxygenation index (OI) from baseline to 60 min after starting iNO in cases and controls. The primary outcome of our study was that the mean absolute change in OI from baseline to after 60 min was higher among cases 10.7 (14), than in controls 6 (22.5), and was not statistically different between the groups. The secondary outcome variable — death before discharge — was found to be significantly higher in cases (55%) than in controls (8%). All the other variables for secondary outcome measures remained statistically insignificant. Conclusion: Infants with PH secondary to AVMs treated with iNO did not respond differently compared to those presented with PH without AVMs treated with iNO. Right ventricular dysfunction on echocardiography was higher in cases than controls (cases: 66.7% and controls: 28.6%) but was not statistically significant. What is Known:• Arterioenous malformation (AVM) is a well-known cause of persistent pulmonary hypertension in newborns. Inhaled nitric oxide (iNO) is most commonly used as first-line therapy for pulmonary hypertension in newborns.• Around 40–50% of vein of Galen malformations (VOGMs) are found to have congestive heart failure in the neonatal period. What is New:• Neonates may present with an isolated PH of the newborn as the main feature of the VOGMs. A large proportion of cases with AVMs have been associated with right ventricular cardiac dysfunction. • Results from one of the largest database registries in the world for iNO have been used to answer our research question.

description: In this paper, we present a proof of concept study for a quantitative method for shunt detection in
silicon solar cells using photoluminescence imaging. The method is based on interpretation of the luminescence
intensity around a local shunt in terms of the extracted current density. The theoretical relationship between the PL
signal and the shunt current is derived. Experimental results on specifically prepared test structures, on intentionally
shunted monocrystalline cells and on shunted industrial multicrystalline cells are presented and compared to shunt
values from dark IV, SunsVoc and Lock in thermography. Good agreement is found for the test structures and for the
intentionally shunted cells. For the multicrystalline cells the shunt values calculated from PL images agree to within
a factor of two with shunt values obtained from other methods.

description: A silicon physically unclonable function (PUF) is considered to be one of the key security system solutions for local devices in an era in which the internet is pervasive. Among many proposals, a PUF using ring oscillators (RO-PUF) has the advantage of easy application to FPGA. In the conventional RO-PUF, frequency difference between two ROs is used as one bit of ID. Thus, in order to obtain an ID of long bit length, the corresponding number of RO pairs are required and consequently power consumption is large, leading to difficulty in implementing RO-PUF in local devices. Here, we provide a RO-PUF using the initial waveform of the ROs. Because a waveform constitutes a part of the ID, the number of ROs is greatly reduced and the time needed to generate the ID is finished in a couple of system clocks. We also propose a solution to a change of PUF performance attributable to temperature or voltage change.

description: Background: X-chromosomal genes contribute to sex differences, in particular during early development, when both X chromosomes are active in females. Double X-dosage shifts female pluripotent cells towards the naive stem cell state by increasing pluripotency factor expression, inhibiting the differentiation-promoting MAP kinase (MAPK) signaling pathway, and delaying differentiation. Results: To identify the genetic basis of these sex differences, we use a two-step CRISPR screening approach to comprehensively identify X-linked genes that cause the female pluripotency phenotype in murine embryonic stem cells. A primary chromosome-wide CRISPR knockout screen and three secondary screens assaying for different aspects of the female pluripotency phenotype allow us to uncover multiple genes that act in concert and to disentangle their relative roles. Among them, we identify Dusp9 and Klhl13 as two central players. While Dusp9 mainly affects MAPK pathway intermediates, Klhl13 promotes pluripotency factor expression and delays differentiation, with both factors jointly repressing MAPK target gene expression. Conclusions: Here, we elucidate the mechanisms that drive sex-induced differences in pluripotent cells and our approach serves as a blueprint to discover the genetic basis of the phenotypic consequences of other chromosomal effects.

description: Objectives To describe first experience of integrating assessment of image quality in paediatric X-ray computed tomography (CT) with analysis of the radiation dose indices to develop reference doses called acceptable quality dose (AQD). Methods Image quality was scored by the radiologists at a tertiary care hospital in Qatar on a scale of 0 to 4 using the recently published scoring criteria. The patients undergoing head, chest and abdomen CT were divided in different weight groups as follows: < 5 kg, 5–< 15 kg, 15–< 30 kg, 30–< 50 kg, 50–< 80 kg and > 80 kg. The images that were clinically acceptable (score of 3) were included for assessment of median values of CTDIvol and DLP to obtain AQDs in different weight groups. Results After initial training in image quality scoring of CT images of 49 patients by three radiologists, the study on 715 patients indicated 665 studies (93%) were clinically acceptable as per scoring criteria. The median CTDIvol values for the above weight groups were 16, 20, 22, 22, 27 and 27 mGy and the median DLP values for these weight groups were 271, 377, 463, 486, 568 and 570 mGy cm, respectively, for head CT. Similar values are presented for chest and abdomen CTs. Conclusions The first ever experience of starting with image quality assessment and integrating it with analysis of dose indices to obtain AQD values shall provide a workable model for others and values for comparison within the facility and in other facilities leading to optimisation. Key Points • The first study to integrate image quality assessment with analysis of patient dose indices shows feasibility for routine practice in other centres. • The values of acceptable quality dose (AQD) were provided for head, chest and abdomen CT of children divided into weight groups rather than age. They shall act as reference values for future studies. • Verification of our findings on proportional increase in exposure parameters (CTDIvol and DLP) with weight by other investigators shall be helpful.Other Information Published in: European Radiology

description: Purpose The American Academy of Orthopaedic Surgeons (AAOS) developed the appropriate use criteria (AUC) for the management of hip osteoarthritis (OA) to guide surgeons in making decisions based on the best available evidence. This study aimed to assess the applicability of the AUC by comparing the actual treatment provided at our institution with the AUC recommendations. Methods A retrospective review of 115 patients who were diagnosed and treated for hip OA at our institution between December 2017 and December 2019 was performed. Data were collected and entered into the AUC application to determine the rate of appropriateness of the provided treatment according to the AUC recommendations. Then, the actual provided treatments were compared with the AUC recommendations to determine the agreement between the two. Results There were 115 patients, with a mean age of 50.08 years (range, 30–80 years). The most frequent patient characteristics were middle age (40–65 years) with function-limiting pain at moderate to long distances, minimal hip OA on X-ray examination, mild range of motion limitation, and presence of modifiable risk factors for negative outcomes. The overall rate of appropriateness and in agreement with the AUC recommendations was 100% for conservative treatments and 80.1% for surgical treatments. Conclusions This study shows that the majority of the hip OA treatments provided at our institution were appropriate and in agreement with the AUC recommendations. Furthermore, the AUC can be easily accessed through a free web application using a computer or smartphone to obtain the recommended treatment for any patient with hip OA.Other Information Published in: International Orthopaedics

description: The efficiencies of the world record III-V metamorphic triple junction (3J) solar cells could be improved further, if their Ge subcells would be replaced by more efficient monolithically grown III-V tandem solar cells. For this purpose we have developed a low band gap tandem solar cell, which is designed to work under an InGaP/GaAs tandem solar cell in a four-junction (4J) configuration. As the top and bottom subcells, InGaAsP (Eg = 1.03 eV) and InGaAs (Eg = 0.73 eV) were grown lattice matched to InP. The serial connection of the subcells was realized by growing a tunnel junction, including highly doped n++-InGaAs and p++-GaAsSb layers. The delicate critical interfaces were prepared by employing metal organic vapor phase epitaxy (MOVPE) and were monitored with optical in-situ reflectance anisotropy spectroscopy (RAS). Isolated tunnel diode structures provided current densities of several thousand A/cm² already in the bias regime of several 100 mV, meaning that voltage losses in the tunnel diode should not be of concern for the solar cells even under extreme concentration ratios (> 1000 suns). Our best cell performance was 7.9% below a 4-μm-thick GaAs filter for 20 suns without an antireflection coating (ARC).

description: Background: X-ray computed tomography is acknowledged as a powerful tool for the study of root system architecture of plants growing in soil. In this paper, we improved the original root segmentation algorithm “Rootine” and present its succeeding version “Rootine v.2”. In addition to gray value information, Rootine algorithms are based on shape detection of cylindrical roots. Both algorithms are macros for the ImageJ software and are made freely available to the public. New features in Rootine v.2 are (i) a pot wall detection and removal step to avoid segmentation artefacts for roots growing along the pot wall, (ii) a calculation of the root average gray value based on a histogram analysis, (iii) an automatic calculation of thresholds for hysteresis thresholding of the tubeness image to reduce the number of parameters and (iv) a false negatives recovery based on shape criteria to increase root recovery. We compare the segmentation results of Rootine v.1 and Rootine v.2 with the results of root washing and subsequent analysis with WinRhizo. We use a benchmark dataset of maize roots (Zea mays L. cv. B73) grown in repacked soil for two scenarios with differing soil heterogeneity and image quality. Results: We demonstrate that Rootine v.2 outperforms its preceding version in terms of root recovery and enables to match better the root diameter distribution data obtained with root washing. Despite a longer processing time, Rootine v.2 comprises less user-defined parameters and shows an overall greater usability. Conclusion: The proposed method facilitates higher root detection accuracy than its predecessor and has the potential for improving high-throughput root phenotyping procedures based on X-ray computed tomography data analysis.

In particular, I review the new features and challenges one faces when constructing various scalar, fermionic and gauge field theories on Moyal space, and especially how the UV/IR mixing problem was solved for certain models. Finally, I outline more recent progress in constructing a renormalizable gauge field model on non-commutative space, and how one might attempt to prove renormalizability of such a model using a generalized renormalization scheme adapted to the non-commutative (and hence non-local) setting.

description: Ventricular dysfunction may be found in 40% of newborns with CDH, and is not only a predictor of disease severity, but also mortality and need for ECMO. We conducted this study to assess the utility of serial echocardiography in management of newborns with CDH and their survival outcomes. This is a retrospective study, wherein the demographic, clinical and echocardiographic data from our local CDH registry and hospital clinical database were analyzed to study the correlation of timed echocardiographic findings with mortality and other outcomes. Fourty-two newborns with CDH were admitted during the study period (M/F:19/23), with median gestation of 38 weeks (IQR:36–39) and birth weight of 2.83 kg (IQR 2.45–3.17). Thirty-one were left-sided, seven right, one central, and three bilateral hernias. Twelve infants (28%) died in early infancy. Three infants were excluded from analysis due to either palliation at birth or significant cardiac anomaly. A total of 137 echos from 39 infants were analyzed. Seventy percent of newborns who died and had an echo within the first 72 h, were noted to have suffered from moderate to severe PH. Birth weight < 2.8 kg, RVSP > 45.5 in the first 72 h and postoperative VIS > 23.5 and RSS > 4.3 were good predictors of mortality. Markers of elevated pulmonary pressures and cardiac function were useful in guiding therapy. Serial timed functional echocardiography (f-Echo) monitoring allows targeted therapy of patients with CDH. Birth weight, initial severity of pulmonary hypertension and postoperative RSS and VIS may be useful in predicting mortality.Other Information Published in: Pediatric Cardiology

Solar Cells, Modules and PV Systems for Space Applications

description: The ability to generate photocurrent under front as well as back illumination makes the bifacial solar cells very promising for low earth orbits (LEO) where the earth’s albedo is significant. Calculations show a 11–41% increase in light power received by cells due to illumination of the solar cell backs. Besides back illumination, an additional contribution in output increase results from the cells transparency in the IR range which decreases equilibrium working temperature. Therefore bifacial Si solar cells are able to supply 18-37 % more energy than regular Si cells. Bifacial cells with an n+-p-p+ structure, are experimentally tested and used for several space vehicle power supplies. Proven energy generation increases of 10-20 % are observed when using bifacial Si solar cells instead of regular Si solar cells. A further increase of energy generation can be expected if bifacial Si cells with improved parameters are used. The advantage of the bifacial solar cell may be characterized by its “equivalent efficiency” which is equal to the efficiency of a regular Si solar cell able to generate the same energy. The “equivalent efficiency” of bifacial Si solar cell in a typical LEO space craft feathered solar array tracking mode, can achieve 25 %.

description: Background: Diabetes associations claim to have a patient-centered approach in diabetes care including shared decision-making (SDM). Diabetes educators are important healthcare professionals for implementing the concept of informed SDM in diabetes care. They need critical health competences (CHC) in order to provide evidence-based information and to support patients in understanding the risks of the disease and also the possible benefits or harm of the healthcare options. Therefore, we surveyed the CHC of diabetes educators. Methods: We performed a cross-sectional survey using the validated Critical Health Competences (CHC) Test to measure CHC of certified diabetes educators and trainees in Germany. Diabetes educators were approached via newsletter, mailing lists or in person during the conference of the German Diabetes Association. Trainees were approached during their training sessions. We applied scenario 1 of the CHC test, which comprises 17 items with open-ended and multiple-choice questions. Mean person parameters with a range from 0 to 1000 were calculated to assess the levels of critical health competences and a multiple linear regression analysis was conducted to determine correlations between sociodemographic variables and levels of CHC. Results: A total of 325 participants, mean age 38.6 (±11.1) years, completed the CHC test; n = 174 (55.5%) were certified diabetes educators and n = 151 (46.5%) were trainees. The participants achieved a mean score of 409.84 person parameters (±88.10) (scale from 0 to 1000). A statistically significant association was found only between the level of education and the level of CHC (b = 0.221; p-value 0.002). Participants with grammar school education achieved higher mean scores compared to participants with secondary school education (432.88 ± 77.72 vs. 396.45 ± 85.95; mean difference 36.42 ± 9.29; 95%CI 18.15 to 54.71; p < 0.0001). Conclusion: Diabetes educators achieved low competence scores and it can be assumed that they do not have sufficient CHC to conduct consultations based on the SDM principles. Poor CHC among healthcare providers are a major barrier for the implementation of SDM. Core concepts of evidence-based medicine should be implemented into the curricula for diabetes educators in order to increase their levels of CHC.

description: Many high-concentrating devices have been
developed in the past, but they have usually
been not cheaper than conventional solar panels.
Research on small PV concentrators [1] shows
that most promising photovoltaic modules are
those that allow for manufacturing solar cells
little different in design and cost from one-sun
cells, built in mono-crystalline silicon. Actually
these cells can be used at concentration ratios up
to 20-40x with efficiencies up to 20 % [2].
The most promising technology is the Line-
Focus Mirror Parabolic Troughs with single axis
tracking and concentration ratio up to 20x,
because it allows for a simple and low cost
tracking system to be used.
Stationary PV/T parabolic collectors have been
developed as well in the past [3]. Nevertheless
even if they are very simple and reliable, they
cannot have good performances in terms of
production per year because they do not track
the sun.
The studied system uses a linear parabolic
reflector to concentrate the sunlight into a string
of mono crystalline cells with a real
concentration ratio of about 20 suns. The cells
are cooled by means of water flowing through
two pipes placed on the back of the cells and
temperature is kept low to prevent cells damages
and to obtain thermal energy recovery.
Mono crystalline photovoltaic cells with
efficiency around 18 % designed by NAREC are
applied in this system. The overall system uses a
low cost one axis solar tracker which does not
require big accuracy in tracking the sun.
The PV/T concentrator has been installed and
outdoor tested in Florence under real operation
conditions. The system has demonstrated good
performances and overall electrical and thermal
efficiency up to 33,3 % have been achieved.
The system described in the paper represents a
low cost and very reliable approach in order to
decrease photovoltaic cost per watt. The mono
crystalline cells are a very tested technology as
the very low concentration ratio does not require
big accuracy.

description: This document is an incremental update of deliverables “D5.2 Cross-sector Policy Lifecycle Management: Design and
 Open Specification 1”, September 2020, and “D5.4 Cross-sector Policy Lifecycle Management: Design and Open
 Specification 2”, August 2021. It details the specification of the tools and technologies used to model Public Policies
 (PPs) as well as the design of the policy development toolkit (including the visualization framework), and the
 mechanisms required for compilation of policy collections to perform cross-sector analysis. The purpose of this series
 of deliverables is to keep track of the specifications throughout the project and update them as the project progresses. This deliverable is the last of the series, has been released in M32 (August 2022) of the project, and its main objective
 is to describe the approach to the policy modelling and validation that will support policy makers in the design,
 evaluation, optimization and adaptation of policies. The Policy Development Toolkit (PDT), along with the Policy Model
 Editor (PME), constitute the front-end of the PolicyCLOUD platform, which allows policy makers to create, update and
 validate policies. The PDT backend, which hides the complexity of storing the data models into persistent storage,
 implements the services that the front-end uses to display the content to the user and provide the necessary user
 experience.

title: Towards just climate futures: exploring islanders’ narratives of hope, movement and loss
Creators: name: Bauza Garcia-Arcicollar, Africa
Publisher: name: University of Reading
Year: 2022

description: The future of island communities has been declared finite, predicting that climate change will result 
in the uninhabitability of many small island developing states (SIDS). As a result, islanders are left 
with few options but to move or to drown. This thesis attempts to challenge this pre-determined 
future by deconstructing the idea of future foreclosure to gain a comprehensive understanding of 
what is required in relation to justice in the context of climate change and SIDS. In particular, it 
focuses on the potential scenario of climate-related migration and displacement from a variety of 
standpoints. First, it explores islanders’ future hopes, aspirations, and imaginings, considering the 
role of climate change and mobility within those. Second, it analyses the implications of leaving 
the islands behind by examining movement and loss. Third, it investigates justice considerations 
for the potential scenario of climate-related migration and displacement on both empirical and 
normative grounds. 
By researching these themes with a range of qualitative methods and a focus on the non-material 
and symbolic dimensions of climate change and life on the islands, this thesis argues that the only 
future that might be considered just is a future on the islands and any form of a future that takes 
place elsewhere constitutes a moral wrong and results in an unjust climate future. In building this 
claim, the thesis sets out the following findings. Islanders’ think of their futures in terms of 
continuity of place and way of life. Further, movement represents a rupture to such way of life 
and climate-related migration and displacement would carry a set of incommensurable losses that 
go well beyond material and economic properties and encompass a range of practices and 
meanings of considerable value to affected populations. Thus, if a future on the islands is 
impossible, then some form of justice-based response will be needed. This thesis outlines a form 
of a reparation effort that foregrounds satisfaction measures in attempting to repair non-material 
and symbolic loss.
