description: Objective To evaluate the effect of a 1-year hybrid closed-loop (HCL) system on glycemic control in children and adolescents with type 1 diabetes (T1D) previously treated with multiple daily injections (MDI). Methods This was a 1-year observational study, as a continuation of the previous 3 months prospective study of pediatric patients with T1D conducted at Sidra Medicine in Qatar. The study enrolled individuals aged 7–18 years with T1D > 1 year, on MDI with self-monitoring of blood glucose or continuous glucose monitoring, with no prior pump experience, and with an HbA1c level < 12.5% (< 113 mmol/mol). After the first 3 months of HCL use, patients were followed at 6, 9 and 12 months, where HbA1c was obtained and pump data were collected. Results All 30 participants (age 10.24 ± 2.6 years) who initiated HCL completed 12 months of HCL system use in Auto Mode. The participants used the sensor 88.4 ± 6.5% of the time with Auto Mode usage 85.6 ± 7.4% during 12 months of HCL system use. HbA1c decreased from 8.2 ± 1.4% (66 ± 15.3 mmol/mol) at baseline, to 6.7 ± 0.5% (50 ± 5.5 mmol/mol) at 3 months (p = 0.02) and remained stable to 7.1 ± 0.6 (54 ± 6.6 mmol/mol) at 12 months (p = 0.02). TIR (70–180 mg/dL) increased from 46.9% at baseline to 71.9% at 1 month and remained above 70% during the 12 months of HCL use. Conclusion HCL system (MiniMed 670G) in children and adolescents previously treated with MDI significantly improves glycemic outcomes (HbA1c and Time in Ranges) immediately during the first month. This improved glycemic control was maintained over the 1 year following Auto Mode initiation.Other Information Published in: Acta Diabetologica

description: Aim The aim of this study was to evaluate the 10-day initiation protocol for MiniMed 670G hybrid closed-loop (HCL) system in individuals with type 1 diabetes on multiple daily injection (MDI) in achieving desirable glycemic control. Methods An open-label single-arm, single-center, clinical investigation in children aged 7–18 years on MDI following a structured protocol: 2 days, HCL system assessment; 5 days, HCL system training (2-h sessions on 5 consecutive days with groups of 3–5 participants and families); 3 days, Manual Mode use of HCL system; 84 days, Auto Mode use of the HCL system, cumulating in 10 days from MDI to Auto Mode activation. Results A total of 30 children (age 10.24 ± 2.6 years) were enrolled in the study, and all completed the planned 84 days on Auto Mode. The participants used the sensor for a median of 92% of the time and spent a median of 89% in Auto Mode. The mean HbA1c decreased from 8.2 ± 1.4% (66 ± 15.3 mmol/mol) at baseline to 6.7 ± 0.5% (50 ± 5.5 mmol/mol) at the end of the study (p = 0.017). Time in range (70–180 mg/dL) increased from 46.9 ± 18.5% at baseline to 75.6 ± 6.9% in Auto Mode (p < 0.001). This was achieved while spending 2.8% of the time below 70 mg/dL and without any severe hypoglycemia or DKA. Conclusion Children and adolescents with type 1 diabetes on MDI therapy can successfully initiate the HCL system, using a concise structured 10-day protocol.Other Information Published in: Acta Diabetologica

description: With the development of flexible, weather-resistant high barrier materials for the encapsulation of
flexible solar cells an innovative, resource-friendly production process for photovoltaic modules can be achieved.
The market of flexible thin film and organic solar cells, such as amorphous silicon (a-Si), microcrystalline silicon
(μc-Si), Copper-Indium-Gallium-Selenide (CIGS) and Copper-Indium-Diselenide (CIS) cells is growing very fast
requiring new techonolgies in terms of cell production and encapsulation.
Today state of the art is encapsulating flexible modules with glass – glass or glass – backsheet set-ups. The used
backsheets provide an incorporated moisture barrier such as an aluminum foil or a metal oxid like AlOx or SiOx.
Such encapsulated modules are limited in flexibility.
Consequently the development of flexible, rollable high barrier material is crucial for thin film and organic solar
cells.
However requirements for flexible encapsulation material in terms of transparency, weatherability and permeability
of gases are very challenging.
Transparency of at least 85 % and permeation values as low as 10-5 g/cm2d for water vapor transition (WVTR) and
respectively 10-5 cm3/m2datm for oxygen transition (OTR) are needed to protect flexible cell systems.
Beside material development processability of the high barrier material in roll to roll manner is very important.
The principle for establishing a flexible high barrier material is a polymer substrate delivering sufficient mechanical
strength and thermal resistance. The polymer substrate is combined with inorganic layers, such as MeOx (SiOx,
AlOx) layers and functional barrier coatings of tailor made hybrid polymers concerning adhesion, UV stability or
weatherability.
With the use of weather-resistant high barrier materials flexible solar cells can be enccasulated in large quantities in a
roll to roll process. An innovative, resource-friendly production process for photovoltaic modules can be achieved.

description: The Technological Institute for the Renewable Energy (ITER) has been the Engineering Procurement
Contractor (EPC) for their installation. ITER has connected its own photovoltaic plants and actually continues
performing their management and maintenance. Due to the size of the four main photovoltaic plants, they are
denominated multi-MW PV plants. Two plants are in Granadilla de Abona, called “SOLTEN” (20 MW) and
“SOLTEN II” (4 MW, where 2MW are installed on the roofs of industrial warehouses), and another two in Arico,
called “Finca Verde” (9MW) and “Finca Roja” (3.6 MW). The geographical proximity between the four photovoltaic
plants and their identical technical design, allow us to acquire and compare the production data. The photovoltaic
production unit plants a 100kW plant. The modules used for the installation present nominal power between 162 and
200 W. Each plant is connected to its corresponding 100 kW inverter. The equivalent solar hours (ESH) measured
during these three years, shows a similar behavior and the average presents 1664 ESH and the yearly standard
deviation of 3,18%.

description: Purpose Subtrochanteric and reverse oblique intertrochanteric fractures are challenging and often difficult to reduce. While intramedullary nailing (IMN) is considered the standard treatment, achieving anatomic reduction prior to fixation is essential. This study aimed to assess the impact of cerclage wiring with IMN on the outcomes and complication rate in treating subtrochanteric and reverse oblique intertrochanteric fractures. Methods This meta-analysis was conducted in line with PRISMA guidelines. The primary outcome was the time to union. The secondary outcomes were operative time, blood loss, quality of reduction, reduction alignment (if in varus), complications and reoperations. PubMed, Cochrane, Web of Science and Google Scholar were searched till July 2021. Articles that compared intramedullary nailing (IMN) versus intramedullary nailing and cerclage wiring (IMN-C) in the treatment of subtrochanteric and reverse oblique intertrochanteric fractures were included. The risk of bias was assessed using the Newcastle–Ottawa scale. Results This meta-analysis included 415 patients with subtrochanteric and reverse oblique intertrochanteric fracture from six comparative studies. Our findings showed that IMN-C was significantly associated with higher mean duration of surgery and blood loss. However, IMN-C had significantly lower mean time to union compared to IMN alone. In addition, IMN-C had lower pooled prevalence of varus reduction and overall complications. Conclusion This study showed that the use of cerclage wiring is associated with lower time to union, lower prevalence of varus reduction and overall complications. Therefore, cerclage wiring augmentation is a safe technique with low complication rate and may be advised whenever open reduction is needed in the management of subtrochanteric and reverse oblique intertrochanteric fractures.Other Information Published in: European Journal of Orthopaedic Surgery & Traumatology

description: We present an analysis of spectrum and variability of the bright reddened narrow line Seyfert 1 galaxy Was~61 using 90 ks archival {\it XMM-Newton} data. The X-ray spectrum in 0.2-10 keV can be characterized by an absorbed power-law plus soft excess and an Fe K$α$ emission line. The power-law spectral index remains constant during the flux variation. The absorbing material is mildly ionized, with a column density of 3.2$\times$10$^{21}$ cm$^{-2}$, and does not appear to vary during the period of the X-ray observation. If the same material causes the optical reddening (E(B-V)$\simeq$0.6 mag), it must be located outside the narrow line region with a dust-to-gas ratio similar to the average Galactic value. We detect significant variations of the Fe K$α$ line during the observational period. A broad Fe K$α$ line at $\simeq$6.7 keV with a width of $\sim$0.6 keV is detected in the low flux segment of the first 40 ks exposure, and is absent in the spectra of other segments; a narrow Fe K$α$ emission line $\sim$6.4 keV with a width of $\sim$0.1 keV is observed in the subsequent 20 ks segment, which has a count rate of 35% higher and is in the next day. We believe this is due to the change in geometry and kinematics of the X-ray emitting corona. The temperature and flux of soft X-ray excess appear to correlate with the flux of the hard power-law component. Comptonization of disc photons by a warm and optically thick inner disk is preferred to interpret the soft excess, rather than the ionized reflection.

description: The paper describes the performance of the grid-connected 1-kW PV system installed on a grammar school in
Poland after eight years of operation. It was designed and installed in year 2000 and from year 2001 it is fully monitored
according to guidelines of standard IEC 61724. System was build with 20 a-Si modules (Millennia MST 50 MV) and Sunny Boy
inverter. Monitoring system consists of set of meteorological and electrical sensors connected to Sunny Boy Plus Controller.
During eight years of operation, system has produced 4430 kWh of energy. Due to the process of stabilization of electrical
parameters of amorphous silicon modules PR values are decreasing during first three years. After the end of that process PR is in
range from 0.52 to 0.6. System Efficiency value is about 3.5%. The inverter efficiency is about 92%.
Data gathered by the monitoring system also enabled to perform wide range of analysis of the influence of meteorological
parameters, such as irradiance on both horizontal and module plane or temperature, on the system parameters, such as System and
PV Generator Losses, System and Inverter Efficiencies, Performance Ratio, or system output electrical parameters, such as DC
and AC output power and output DC voltage.

description: Highly developed and sophisticated production techniques of modern solar cells with functional optical
elements show the need for a quick, precise, cost effective and operator-friendly characterisation technique. Variable
Angle Spectroscopic Ellipsometry (VASE) can fulfil this task. Even though well established for a range of known
materials, the application to new materials isn’t always straightforward. Since VASE is based on an iterative modelling
process by optimisation of some figures of merit, there is a lot of experimental work to do to prove assumptions about the
sample which must be made beforehand. In this work, we correlate PECVD deposition parameters with VASE model
parameters and certain features of hydrogenated amorphous silicon carbide (a-SixC1-x:H). a-SixC1-x:H is a very versatile
material that can be adapted to a very wide range of concepts to enhance the efficiency of silicon solar cells. To prove
this, we show the production of a Bragg filter consisting of ten alternating layers of this material.

description: The following paper presents a new substance with the potential to substitute 2-propanol as a texturing agent in solar cell processes with an additional cleaning capability. This allows to combine the cleaning after wiresawing with the texturization into one single process. The substance was selected from a pool comprising 45 different organic compounds. This promising substance combines a relative good texture capability, a high etch-rate in basic solution, high process stability, low toxicity and reasonable price availability. This compilation of qualities represents relevant requirements for a texturing agent to be brought into industrial scale operation. In tandem with its cleaning functionality, this surfactant allows to perform a new sequence of processes where the texturing step can take place at the beginning of the solar cell production chain. It was proved that mono-crystalline silicon wafers processed with this surfactant acquired a higher mechanical stability than those following standard process conditions. High mechanically stable wafer manufacture together with a shortened new sequence of processes between wafering and emitter diffusion can lead to a strong reduction of breakage rate during the solar cell production.

description: This thesis explores the experiences and needs of women who were aged between 10 and 25 when their mothers passed away. The findings reveal that the experience of maternal loss during adolescence is unique and influenced by multiple contextual factors. Existing organisations are providing invaluable support to maternally bereaved women, however organisations face many barriers in providing said support. Narrative therapy approaches were identified as an appropriate supportive intervention, though greater emphasis on grief and bereavement support training for post-graduate psychology students is essential.

description: Objective The purpose of this study was to perform a meta-analysis comparing mobile-bearing with fixed-bearing total knee arthroplasty (TKA) in terms of all-cause revision rates, aspetic loosening, knee functional scores, range of motion and radiographic lucent lines and osteolysis. Methods PubMed, Cochrane Library, Google Scholar and Web of Science were searched up to January 2020. Randomized controlled trials that compared primary mobile-bearing with fixed-bearing TKA, reporting at least one of the outcomes of interest, at a minimum follow-up of 12 months were included. All outcomes of interest were pooled at short-term (< 5 years), mid-term (5 to 9 years) and long-term (> = 10 years) follow-up intervals. Results A total of 70 eligible articles were included in the qualitative and statistical analyses. There was no difference between mobile-bearing or fixed-bearing TKA at short-term, mid-term and long-term follow-ups in all outcome measures including all-cause revision rate, aseptic loosening, oxford knee score, knee society score, Hospital for Special Surgery score, maximum knee flexion, radiographic lucent lines and radiographic osteolysis. Conclusion The current level of evidence demonstrated that both mobile-bearing and fixed-bearing designs achieved excellent outcomes, yet it does not prove the theoretical advantages of the mobile-bearing insert over its fixed-bearing counterpart. The use of either design could therefore be supported based on the outcomes assessed in this study.

description: Proper balance between exploitation and exploration is what makes good decisions, which achieve high rewards like payoff or evolutionary fitness. The Infomax principle postulates that maximization of information directs the function of diverse systems, from living systems to artificial neural networks. While specific applications are successful, the validity of information as a proxy for reward remains unclear. Here, we consider the multi-armed bandit decision problem, which features arms (slot-machines) of unknown probabilities of success and a player trying to maximize cumulative payoff by choosing the sequence of arms to play. We show that an Infomax strategy (Info-p) which optimally gathers information on the highest mean reward among the arms saturates known optimal bounds and compares favorably to existing policies. The highest mean reward considered by Info-p is not the quantity actually needed for the choice of the arm to play, yet it allows for optimal tradeoffs between exploration and exploitation.

Two models have been extensively trained and combined to achieve this effect. Sounds are recommended based on the image scene and the headings are generated using a combination of natural language processing and state-of-the-art computer vision models. A Top 5 accuracy of 67% and a Top 1 accuracy of 53% have been achieved. It is also worth mentioning that this is also the first model of its kind to make this forecast.Other Information Published in: Multimedia Systems

description: We report on the results of Swift and XMM-Newton observations of SMC X-2 during its last outburst in 2015 October, the first one since 2000. The source reached a very high luminosity ($L \sim 10^{38}$ erg s$^{-1}$), which allowed us to perform a detailed analysis of its timing and spectral properties. We obtained a pulse period $P_{\rm spin}$ = 2.372267(5) s and a characterization of the pulse profile also at low energies. The main spectral component is a hard ($Γ\simeq 0$) power-law model with an exponential cut-off, but at low energies we detected also a soft (with kT $\simeq$ 0.15 keV) thermal component. Several emission lines can be observed at various energies. The identification of these features with the transition lines of highly ionized N, O, Ne, Si, and Fe suggests the presence of photoionized matter around the accreting source.

description: After the development of the Elkem Solar Silicon process, Q-Cells AG, Pillar JSC and Elkem Solar AS have started the qualification program for Elkem Solar Silicon on solar cells out of an industrial manufacturing process on large scale. In the presentation details on the status and most recent results from the test program are given. The manufacturing process in the pilot plant of Elkem Solar AS is in terms of scale-up factors and critical equipment very close to the planed production process on industrial scale. A significant amount of Elkem Solar Silicon was converted to ingots, wafers and solar cells, using industrial standard equipment and slightly modified manufacturing processes. The material yield for the volumes shipped to Q-Cells AG was comparable to virgin poly-silicon taking into account standard specifications. The results on a block level confirmed same lifetime levels as in the blocks made from the virgin poly-silicon reference. Results on multicrystalline solar cells demonstrate average efficiencies well above 15% and no significant difference compared to the poly-silicon reference. Finally the potential for application of ESS feedstock in future high efficiency cell concepts is addressed.

description: Light induced plating (LIP) of silver on screen-printed contact has been explored, through understanding of the bath, to form high quality contacts to high sheet resistance emitters. The high series resistance of a screen printed cell has been decreased by LIP action which resulted in higher fill factor. We noted that a 45-second LIP decreases the contact resistance by reducing the glass layer thickness at the edge of the metal grid. While a 5-10 minutes LIP, first decreases the glass layer thickness and then plates silver metal onto the metal grid and the silver crystallites at the periphery of the grid. This decreases both the contact and finger resistance which impacts the fill factor. In this study we explored three LIP baths (baths A and B are cyanide free and C-cyanide based) with varying pH from three different companies. Baths B and C was of higher pH and favored a short time LIP than A. High pH bath dissolves lead glass layer faster and plates at slower rate. Therefore, longtime plating in such bath results in pealing of the metal grid. On the other hand, the bath with medium pH dissolves the glass slower and plates the silver at equal rate, and does not have a negative effect on the metal grid adhesion. We used bath A to achieve finger height of ~28 μm tall after 5-10 minutes LIP and average finger width of ~103 μm. We achieved efficiency of 17.7% with a short circuit current density of 36.5 mA/cm2, fill factor of 0.770 and open circuit voltage of 629 mV on 149 cm2 Cz 80-Ω/sq emitter.

description: The front grid of screen printed solar cells strongly limits the efficiency in terms of shading and
resistive losses. Main focus of this work was to provide an alternative two-step front contact process consisting of
fine printing followed by an adapted plating stack of Ni/Cu/Sn. Results on improved fine line printing as well as a
new plating technique will be presented for the first time.
Optimized parameters for printing with newly developed techniques as well as adapted plating techniques will be
shown. Solar cells using the new developed front metallization have been characterized and compared with standard
screen printed solar cells. Efficiency gain of more than 0.4% has been achieved so far.

description: For predicting the annual energy yield of photovoltaic systems under real operating conditions, the
most important quantities are the real nominal power and the irradiance and temperature dependencies. Usually the
module data sheet only provides rated power and temperature coefficient at standard test conditions. This paper
determines all three parameters for twelve different photovoltaic technologies from one year field data at two
locations. It shows that the nominal power from field data in most cases is much lower than the rated power. The
temperature coefficients are constant versus irradiance, with thin film technologies showing better values. Most thin
film technologies exhibit a better low light performance than crystalline silicon (c-Si) modules. The HIT technology
offers a more favorable low light and temperature dependence than the other c-Si modules. Detailed investigations
reveal, however, that the apparent low light performance and temperature coefficients strongly depend on the
peculiar conditions of the analysis. Remarkable differences occur due to the kind of the irradiation sensor, the
selection of data, the location and between laboratory and field data.

description: In order to decrease production costs of multicrystalline silicon solar cells, increasing the ingot mass and reducing the process time are two possibilities to be pursued. The goal of the presented joint research project is the production of 1000 kg ingots and the simultaneous increase of the crystallisation velocity compared to the stan-dard process. The higher ingot volume gives rise to the question if there are differences in the incorporation and dis-tribution of the omnipresent main impurities being interstitial oxygen (Oi), substitutional carbon (CS), the interstitial nitrogen-pairs (NN) and the nitrogen-oxygen complex (NNO). The increased crystallisation velocity could cause higher dislocation densities in the ingot. The status of ingot mass up to now is presented, simulations and experimen-tal results addressing the developments mentioned are the main contents of this paper.

description: One of the most important steps in today’s crystalline silicon (c-Si) photovoltaic (PV) industry is slicing silicon (Si) ingots by means of a silicon carbide (SiC) abrasive suspension using a multi-wire slurry saw (MWSS). In this technology, Si material usage yield (Si substrate (wafer) surface area produced per kilogram of Si material loaded in the MWSS tool - m2/kg) increases with decreasing wafer thickness, wire diameter, and abrasive grit size. The goal of this paper is to provide the PV crystalline Si wafering industry with further knowledge on the
impact of abrasive grit properties (size and shape) on slicing efficiency and wafer quality (TTV and kerf loss). The joint efforts of a SiC grit producer and a MWSS manufacturer has led to a comprehensive study. A good correlation between laboratory equipment and wire saw has been found. The results indicate that material removal rates increase with increasing grit size and decreasing circularity. The impact of grit shape on material removal rate and wafer quality is elucidated for the first time in multi-wire silicon slicing.

description: We propose new concepts for efficient light absorption in nanoscale metal-semiconductor-metal
structures. These properties are achieved by controlling light-matter interactions in metal-semiconductor gratings
with 100 nm pitch. We demonstrate record external quantum efficiencies (above 40 %) in nanoscopic metal-GaAs
wire arrays. Applications of these concepts to extremely thin solar cells are discussed.

description: Quantum wells enable solar cell bandgaps to be tailored to the theoretical optimum, under the
assumption of unity absorption. In practice however, quantum well regions are thinner and hence absorb less
strongly than bulk material. We predict detailed balance efficiency limits for varying levels of absorptivity in
single- and double-junction quantum-well solar cells. These calculations allow us to find the absorption levels
required for quantum wells to increase cell performance. It is found that the ideal band edge under concentration
for a conventional single-junction cell for all bulk absorptivities lies near 1100nm, whilst for quantum well solar
cells it is pinned at approximately 925nm for quantum well absorptivities up to ~90%. In the case of tandem cells
our model indicates that bottom cell QWs should be advantageous for low absorptivities whilst additional top cell
QWs improve performance for absorptivities above 50%. The effect of increased bottom cell photocurrent due to
radiative losses in the top cell is also quantified.

description: Fibre reinforced polymers present an interesting encapsulation medium for PV-modules. Glass fibres
can provide increased strength and stiffness to thin polymer layers overcoming the brittleness and limited
deformability of glass-panes. Glass fibre reinforced polymers allows for transparency over a broad range of the solar
spectrum while the material properties and integral production processes create possibilities for novel product
concepts with embedded PV technology. To explore such possibilities, innovative design methods were used to
design novel PV product concepts for applications in the build environment.
In our paper three conceptual designs are presented; (1) a thin film module with an adjoining interconnection system
functioning as structural element for geodetic roofing structures, (2) a PV lamella with single-axis tracking utilizing a
linear concentration effect caused by the geometry of the product and the materials applied, and (3) a prepreg PVmaterial
which allows for easy shaping during the production of PV modules with complex geometries. Each concept
employs a specific PV technology and demonstrates a possible application aimed at a specific market. In this way we
show the potential of integration of PV technology in fibre reinforced composites. The paper will be illustrated by
concept renderings.

description: Since the release of LAMOST (the Large Sky Area Multi-Object Fiber Spectroscopic Telescope) catalog, we have the opportunity to use the LAMOST DR2 stellar catalog and \emph{WISE All-sky catalog} to search for 22 $μ$m excess candidates. In this paper, we present 10 FGK candidates which show an excess in the infrared (IR) at 22 $μ$m. The ten sources are all the newly identified 22 $μ$m excess candidates. Of these 10 stars, 5 stars are F type and 5 stars are G type. The criterion for selecting candidates is $K_s-[22]_{μm}\geq0.387$. In addition, we present the spectral energy distributions (SEDs) covering wavelength from optical to mid-infrared band. Most of them show an obvious excess from 12 $μ$m band and three candidates even show excess from 3.4 $μ$m. To characterize the amount of dust, we also estimate the fractional luminosity of ten 22 $μ$m excess candidates.

procedures for PV building products and proposals for tests for novel BIPV technology like thin film. The test
proposed are a module breakage test for BIPV products, a fire safety test for BIPV products and a dynamic load test
for BIPV products. Furthermore first proposals of how flexible PV modules could be tested in an appropriate way to
ensure long time quality and safety of these new products are presented.

description: Graphene/carbon-nanotube (CNT) hybrid material can be useful in energy storage and nanoelectronic technologies. Here we address the CNT-oscillator encapsulated in a graphene-nanoribbon (GNR) trench as a novel design, and investigate its properties via classical molecular dynamics simulations. Since the energy barrier was very low while the CNT was encapsulated in the GNR trench, the CNT absorbed on the GNR surface could easily be encapsulated in the GNR trench. MD simulations showed that the CNT oscillator encapsulated in a GNR trench is compatible with simple CNT oscillators, so we anticipate that the CNT in GNR trench could work as an oscillator. So we can anticipate that the CNT encapsulated in a GNR trench can be applied to ultra-sensitive nanoelectromechanical oscillators, and this system has the possibility to be applied to relay-switching devices, and to shuttle memory.

description: Although maps of solar irradiance are available, they don’t have a sufficient resolution to consider the
influence of the surrounding constructions and of natural elements such as trees, vegetation and small hills. A
detailed knowledge of the solar radiance is instead necessary to evaluate the potential of solar technology (active and
passive) and to orientate choices, decisions and investments in energy and urban plans. The UiSOL project (Urban
integrated Solar Technologies) analyzes the relationship between different variables that characterize the urban
layout and consequently its solar active and passive potential and, in order to prevent an indiscriminate use of solar
application and to invest economic and space resources in the more effective way possible, also evaluate various
methods of utilization to find a good balance between technical and aesthetical requests.

description: Recent research in disaster informatics demonstrates a practical and important use case of artificial intelligence to save human lives and suffering during natural disasters based on social media contents (text and images). While notable progress has been made using texts, research on exploiting the images remains relatively under-explored. To advance image-based approaches, we propose MEDIC (https://crisisnlp.qcri.org/medic/index.html), which is the largest social media image classification dataset for humanitarian response consisting of 71,198 images to address four different tasks in a multi-task learning setup. This is the first dataset of its kind: social media images, disaster response, and multi-task learning research. An important property of this dataset is its high potential to facilitate research on multi-task learning, which recently receives much interest from the machine learning community and has shown remarkable results in terms of memory, inference speed, performance, and generalization capability. Therefore, the proposed dataset is an important resource for advancing image-based disaster management and multi-task machine learning research. We experiment with different deep learning architectures and report promising results, which are above the majority baselines for all tasks. Along with the dataset, we also release all relevant scripts (https://github.com/firojalam/medic).Other Information Published in: Neural Computing and Applications
