[more ▼]The Martian ultraviolet dayglow provides information on the basic state of the Martian upper atmosphere. The Imaging Ultraviolet Spectrograph (IUVS) on NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has observed Mars at mid and far-UV wavelengths since its arrival in September 2014. In this work, we describe a linear regression method used to extract components of UV spectra from IUVS limb observations and focus in particular on molecular nitrogen (N[SUB]2[/SUB]) photoelectron excited emissions. We identify N[SUB]2[/SUB] Lyman-Birge-Hopfield (LBH) emissions for the first time at Mars and we also confirm the tentative identification of N[SUB]2[/SUB] Vegard-Kaplan (VK) emissions. We compare observed VK and LBH limb radiance profiles to model results between 90 and 210 km. Finally, we compare retrieved N[SUB]2[/SUB] density profiles to general circulation (GCM) model results. Contrary to earlier analyses using other satellite data that indicated N[SUB]2[/SUB] densities were a factor of three less than predictions, we find that N[SUB]2[/SUB] abundances exceed GCM results by about a factor of two at 130 km but are in agreement at 150 km.

[more ▼]The Imaging UltraViolet Spectrograph (IUVS) on the MAVEN spacecraft has detected two distinct types of auroral emission on Mars. First, we report the discovery of a low altitude, diffuse aurora spanning much of Mars’ northern hemisphere coincident with a solar energetic particle outburst. IUVS observed northerly latitudes during late December 2014, detecting auroral emission in virtually all nightside observations for ~5 days spanning virtually all geographic longitudes. The vertical profile showed emission down to ~70 km altitude (1 microbar), deeper than confirmed at any other planet. The onset and duration of emission coincide with the observed arrival of solar energetic particles up to 200 keV precipitating directly and deeply into the atmosphere. Preliminary modeling of the precipitation, energy deposition and spectral line emission yields good matches to the observations. These observations represent a new class of planetary auroras produced in the Martian middle atmosphere. Given minimal magnetic fields over most of the planet, Mars is likely to exhibit aurora more globally than Earth.Second, we confirm the existence of small patches of discrete aurora near crustal magnetic fields in Mars' southern hemisphere, as observed previously by SPICAM on Mars Express (Bertaux et al., Nature, 435, 790-794 (2005)). IUVS observed southern latitudes in July and August 2015, detecting discrete auroral emission in ~1% of suitable observations. Limb scans resolved both vertically and along-slit indicate this type of auroral emission was patchy on the scale of ~40 km, and located at higher altitudes ~140 km. The higher altitudes imply a lower energy of precipitating particles. The mix of spectral emissions also differed signficiantly from the diffuse aurora, indicating different excitation and quenching processes.We will discuss the observed properties of the aurora and associated charged particle precipitation, as well as the broader implications of this high-energy deposition into Mars' atmopshere.

[more ▼]« Il ne faut pas travailler pour un monde qui disparaît mais pour un monde nouveau dont on peut prévoir l’avènement ». Architecte par vocation et formation, puis commerçant, ensuite créateur et industriel, le Liégeois Gustave Serrurier (1858-1910) est rapidement convaincu de la nécessité de lier l’architecture aux arts décoratifs. Il le fait avec la conviction politique et esthétique qu’une production industrialisée permettra de donner au plus grand nombre l’environnement artistique auquel tout être peut prétendre. Il pressent que le temps de l’artisanat est en passe d’être révolu et équipe progressivement ses ateliers de machines modernes. Si ses premières créations restent empreintes de l’esprit constructif des artisans néogothiques, s’il emploie ensuite des jeux de lignes courbes, tendues et maîtrisées, le début du XXe siècle le voit évoluer vers toujours plus de simplicité constructive et plus de rigueur géométrique. Grâce au mobilier, aux objets et aux aménagements d’intérieurs qu’il crée et fait réaliser par la centaine d’ouvriers de ses ateliers liégeois, sa firme prend rapidement une ampleur internationale et se fait remarquer dans les expositions universelles comme celle de Saint-Louis (U.S.A.) en 1904. Anticipant sur ce que seront les motivations d’un Bauhaus, ses préoccupations sociales et esthétiques conduisent Serrurier à imaginer un mobilier de plus en plus économique, rationnellement construit, adapté à l’usage et au lieu de destination, par exemple pour une habitation ouvrière à l’Exposition universelle de Liège en 1905. Là, un mobilier en orme équipe la salle commune égayée d’une frise au pochoir et de rideaux de lin garnis de carrés colorés. On y remarque un meuble à usage multiple, tout à la fois armoire, secrétaire et bibliothèque, sans autre décor que sa composition équilibrée ; banc, table et chaises sont faits d’éléments assemblés par des vis apparentes. C’est à cette même époque que Serrurier développe la ligne “Silex”, particulièrement représentative ; conçue de façon tout à fait originale et pragmatique, exécutée en bois blanc et décorée au pochoir, la plupart des assemblages de menuiserie sont remplacés par des vis apparentes. La découpe des planches se montre économe en matière. Une chaise, objet d’utilité commune, se doit d’être robuste, ergonomique et peu coûteuse à produire : ici, la production en série est aisée et pourra être assurée dans ses ateliers équipés de scies mécaniques et autres machines-outils. A l’examen, une chaise de cette série exprime bien les qualités de designer industriel de son concepteur et le place à l’avant-garde de son temps ; elle illustre aussi ses ambitions, tant sociales qu’esthétiques, et sa volonté d’un « art pour tous ».

[more ▼]The offshore wind energy development is highly affected by the condition of the weather at sea. Hence, it demands a well-organized planning of the overall process starting from the producers’ sites until the offshore site where the turbines will finally be installed. The planning phase can be supported with the help of Discrete Event Simulation (DES) where weather restrictions, distance matrix, vessel characteristics and assembly scenarios are taken into account. The purpose of this paper is to simulate the overall transport, assembly and installation of the wind turbine components at sea. The analysis is carried out through DES considering both the real historical weather data (wind speed and wave height) and probabilistic approach. Results of the study, applied to the real Offshore Wind Farm (OWF) configuration, are showing a good agreement between the two proposed models. The results point out that the probabilistic approach is highly affected by the semi-random numbers used to model the stochastic behavior of the input variable so that several iterations (200 to 400) are required to reach the convergence of the simulation outputs. We suggest that seasonality of the outputs of both models are preserved, i.e. the variation of the results depending on the variation of the weather along the year. These findings provide a new framework to address risks and uncertainties in OWF installations.

[more ▼]Because of the intermittent nature of solar irradiances, micro-scale solar thermal power systems almost never operate in nominal operating conditions. They are characterized by strong transients and require robust, fast and accurate dynamic simulation tools to permit a proper evaluation of their performance. Model reduction, i.e. the simplification of detailed models, is an attractive method to improve the computational efficiency while simulating such systems. In this context, a µCSP plant featuring a solar field of parabolic troughs, a thermocline storage and a 5kWe power unit is investigated. Both the solar field and the thermocline storage are modeled with complex and simplified methods. The whole power plant is simulated under identical operating condition and deviations between the simulation results are analyzed. Benefits and limitations of the current modeling approach are assessed. Improvements for the modeling of the thermocline storage are identified, implemented and validated. The Modelica language is used as simulation tool and the models developed in this work are integrated in the open-source ThermoCycle library.

[more ▼]In this paper is presented the analysis of a concrete building exposed to OZone fire. The temperature development in the elements and the structural behaviour were calculated in SAFIR using beam elements for the columns and beams and shell elements for the floor slabs. The first floor was modelled and the effects of action from the upper storeys are applied as external loads. It is shown how the numerical analysis allows understanding the behaviour of the structure when exposed to a natural fire until complete cooling by analysing the evolution of displacements, the distributions of bending moments in the beams, the membrane forces in the slab, and the stresses in the elements. All this detailed information would not be available from an experimental test.

[more ▼]This work presents an analysis of the behaviour of different structural members under natural fires, with the aim to characterize their sensitivity to the fire decay phase. Thermo-mechanical numerical simulations based on the non-linear finite element method are conducted using the parametric fire model of Eurocode to represent the natural fires. Results show that, for all the studied members (column, beam) and materials (reinforced concrete, steel, timber), structural failure during or after the cooling phase of a fire is a possible event. The major factors that promote delayed structural failure are the thermal inertia and the constituting material of the member. An indicator is proposed to quantify the propensity to delayed failure for structural members under natural fire. This work enhances the understanding of the structural behaviour under natural fires and has implications for the safety of the fire brigades and people proceeding to a building inspection after a fire.

[more ▼]In this paper the optimal operation of an Organic Rankine Cycle (ORC) unit is investigated both in terms of energy production and safety conditions. Simulations on a validated dynamic model of a real re- generative ORC unit, are used to illustrate the existence of an optimal evaporating temperature which maximizes energy production for some given heat source conditions. This idea is further extended using a perturbation based Extremum Seeking (ES) algorithm to find online the optimal evaporating tempera- ture. Regarding safety conditions we propose the use of the Extended Prediction Self-Adaptive Control (EPSAC) approach to constrained Model Predictive Control (MPC). Since it uses input/output models for prediction, it avoids the need of state estimators, making of it a suitable tool for industrial applica- tions. The performance of the proposed control strategy is compared to PID-like schemes. Results show that EPSAC-MPC is a more effective control strategy as it allows a safer and more efficient operation of the ORC unit, as it can handle constraints in a natural way, operating close to the boundary conditions where power generation is maximized.

Each method is characterized by advantages, limitations and a level of complexity. This contribution aims to assess the impact of the modeling approach on the performance prediction of ORC systems. To this end, a 2.8 kWe ORC unit is investigated as case study. In this paper, the components of the test bench are modeled using different approaches of increasing complexity and each model is calibrated using experimental data from the test rig. The goodness of fit as well as the benefits and limitations of each modeling methods are analyzed and discussed.

[more ▼]In the field of shelving structures for the storage of goods realized adopting tubular members, an interesting connection typology to be used to fasten the vertical columns to the beams is represented by bolted connections with long bolts in shear. With reference to this kind of connections, the authors have already performed a wide experimental and numerical investigation highlighting the occurrence, in this specific case, of local buckling phenomena. In this paper, the attention is focused on the influence of local buckling on the connection resistance, which is neglected by the current version of EC3 in the prediction of the resistance of shear connections of plates. In particular, starting from the results of the experimental and numerical analyses previously performed, in the present paper a formulation for predicting the bearing resistance of the examined connection able to account for the phenomenon of local instability is set up.

[more ▼]Within the concept of "vulnerability" - considered as an inherent or innate value of the human being, from which it is necessary to start in order to build a genuine social policy- the children's vulnerability occupies a special position. Traditionally, children have been treated as objects of protection and not as subjects of rights according to an authoritarian and paternalistic perspective. Over time, a different view of this matter has developed, and it has put the child at the center of attention, considering his vulnerabilities, needs and interests. This perspective has been reflected in the legislation, in case law and doctrine, both internationally and nationally. The concept of "best interest" is the key for addressing children's vulnerability of children and developing substantive equality for them. The European Court of Human Rights in Strasbourg and the Court of Justice of the European Union in Luxembourg have defined this concept in different areas: in the field of international child abduction, immigration, asylum and family reunification, custody and parental responsibility. Although these two tribunals have grounded their arguments on different legal perspectives, both have shown and still show a trend towards convergence to common points, through a balanced consideration of rights in this area. This communication aims at examining the relevant jurisprudence of the aforementioned tribunals about the notion of "best interest" of the child. The case-law since 2011 until 2015 has been taken into account.

[more ▼]The Silurian – Devonian succession have been deposited in wide sags and sub-basins in a cratonic setting, along the northwestern passive margin of the Gondwana during the opening of the proto-Tethyan ocean. During this Siluro-Devonian Period, a high subsidence occurs stacked sediment bodies and organic-rich shales were deposited in many places that respectively form important hydrocarbon reservoirs and source rocks throughout North Africa basins and Arabia (Boot et al., 1998 ; Lüning et al., 2000), which lead Algeria to hold the fourth position in terms of the estimates of technically recoverable shale oil and shale gas resources, based on major basin assessment in the world (EIA, 2013). In the prolific Illizi and Berkine basins (western Ghadames, Algeria) a basin-wide approach is needed, especially with the new “shale gas and shale oil” frontier in the upcoming years, in order to capture regional trends and re-assessment on organic-rich (‘hot’) shale unites which in smaller-scale industrial studies are overlooked. Berkine Basin covers nearly 102.000 km2. This basin has been a thick sedimentary series of 7000 m corresponding to complex reservoirs but also black shales of the basal Silurian and Frasnian respectively major and secondary source rock systems. Wireline-logs from more than 146 (Berkine – Illizi Basins) Algerian petroleum exploration wells have been studies (Djouder et al., 2012; Djouder et al., 2014), and recently 03 months extensive field study of outcrops of the Siluro-Devonian sediments was carried out at the south margin (SE, Tassili n’Ajjer) of the basin. The following analysis incorporates biostratigraphic, ichnological, sedimentological and high resolution stratigraphic data, which provides a framework evolution from offshore to deltaic deposition for the Silurian then fluvial to normal-marine depositional conditions for the Devonian. A total of 06 short-term, third-order sequences can be identified for the Silurian deposits: (i) 'Hot Shale' Oued Imihrou Formation, organic-rich shales with carbonates nodules (Si-1); (ii) above is the Atafaïtafa Formation 500 to 650 m thick with HCS, gutter casts and Cruziana Ichnofacies (Si-2, Si-3); (iii) then overlaid by coarsening-shallowing-upward units. These sequences (Si-4, Si-5 & Si-6) with Storm-wave dominated and Skolithos Ichnofacies are interpreted to reflect deltaic origin. This delta is the result of a significant sea-level drop during the Upper Silurian (Beuf et al, 1971) but also from the high sedimentation rates prograding northwards (Eschard et al., 2005). Devonian deposit also can be divided into fourth third-order sequences (Dev-1 to 4), by the same previous analysis. The base of the cycle is the Caledonian unconformity linked to a tectonic event which affected most of the Gondwanan margin at the Silurian – Devonian boundary and a major relative sea-level fall (Eschard et al., 2005). Previous sequences defined from Tassili n’Ajjer outcrops are well recognized at the basin-scale (Berkine Basin) and can be correlated in the subsurface of the Illizi – Berkine basins (Djouder et al., 2012). Finally, the full depositional cycle for the Silurian – Devonian is reached and capped by the Frasnian maximum flooding surface, with black shales across North Africa (Algeria, western Libya and southern Tunisia) and which are also developed in many parts of the world (Lüning et al., 2003).

This paper presents the analysis of continuous, high-resolution temperature profiles measured along the boreholes length. The undisturbed ground temperature measurements indicate heat loss from ground structures located close to the boreholes. A 3D numerical model is presented to reproduce the measured temperature profiles. Temperature profiles during hardening of the grouting material indicate extended fractured zones in the rock mass. Temperature measurements during the recovery phase of a Distributed Thermal Response Test indicate the succession of rock layers with different mineral content. The results are in good agreement with those of the borehole televiewer logging method. The presented analysis could provide information on bedrock heterogeneity, on the anisotropic thermal behaviour of the rock mass and on the ground temperature variations due to heat loss from ground structures. These information could significantly contribute to the long-term behaviour prediction of the geothermal system and the geothermal reservoir potential.

[more ▼]By construction, a video is a series of ordered frames, whose order is defined at the time of the acquisition process. Background subtraction methods then take this input video and produce a series of segmentation maps expressed in terms of foreground objects and scene background. To our knowledge, this natural ordering of frames has never been questioned or challenged. In this paper, we propose to challenge, in a prospective view, the natural ordering of video frames in the context of background subtraction, and examine alternative time orderings. The idea consists in changing the order before background subtraction is applied, by means of shuffling strategies, and re-ordering the segmentation maps afterwards. For this purpose, we propose several shuffling strategies and show that, for some background subtraction methods, results are preserved or even improved. The practical advantage of time shuffling is that it can been applied to any existing background subtraction seamlessly.

[more ▼]the surface preparation of metal parts made by additive manufacturing (AM). AM is a technology of choice for manufacturing of parts with complex shapes (heat exchangers, RF supports, optical parts…) and integrated functions such as conformal cooling channels, clips, hinges, etc. This opens the door for lightweight parts which are of prime importance for space applications. The potential of the AM technologies is however impeded by the quite rough surface finish that is observed on the as-manufactured parts. It is known that such a finish is likely to impact the performance of the parts. Several post-treatment techniques can be applied to improve the surface condition of the AM parts. However, so far, the influence of the successive post-processing steps on the final properties is not well established. Therefore, a better understanding of the impact of surface characteristics on the material behaviour is needed to expand the use of AM for high performance parts. The objective of this study, supported by ESA, is to propose and evaluate various surface finishing techniques for parts made by the AM technologies, in order to check their compatibility, evaluate their properties and derive guidelines for future applications. CRM is the prime proposer of this study and is in charge of the surface treatment and characterisations. Sirris additive manufacturing facilities are used to produce the parts. Thales Alenia Space and Walopt are included into the industrial team to provide concrete application cases. The study focuses on metals. Two metals under study are presented here: AlSi10Mg and Ti6Al4V. This paper is devoted to the early results of the first steps of surface preparation, namely material removal from the surface of the produced parts in order to improve their surface properties. As a first phase, tribo-finishing (TF) is tested on prototype parts to check its capabilities. Surface and volume parameters are analyzed, namely achieved roughness, material removal rate, location of removed material. The limitations in terms of geometry and applicability are discussed as well. These first observations should serve as guidelines for further application of AM for the design of parts used in space industry.

[more ▼]Anthropogenic debris (AB) contaminate oceans and affect marine organisms in several ways. Plastic production is constantly increasing and it is estimated that 10% of this production end in the seas. As a consequence, plastic is considered as an emerging contaminant and ingestions by organisms are increasingly reported. Microdebris (< 5mm) are available for a high range of organisms, including planktivorous fish, such as the European anchovy (Engraulis encrasicolus). Planktivorous fish have a particular gill basket, with long and tight gill rakers, related to their diet. Upon these gill rakers, small structures called denticles are present. These gill rakers act as a net to trap organic particles and AB. The aim of our study was to correlate sizes of AB ingested with the mesh constituted by the gill rakers and associated structures. Fifteen stomach contents were analyzed by Raman spectroscopy and particles were measured. Five gill arches were observed with a scanning electron microscope. Cellulose fibers and microplastics were the most AB ingested. Comparing to other Clupeiformes (pilchard and Atlantic herring), anchovies have more denticles on each gill rakers (personal data). AB ingestion by fish is poorly studied and impacts of AB are not much understood. Clupeiformes play a major role in marine ecosystems and is the most consumed order by humans. As the branchial basket constitutes a food selective apparatus, more morphological studies dealing with AB ingestion on Clupeiformes are needed.

While much effort have been devoted to the development of robust background models, the automatic spatial selection of useful features for representing the background has been neglected. In this paper, we propose a generic and tractable feature selection method. Interesting contributions of this work are the proposal of a selection process coherent with the segmentation process and the exploitation of global foreground models in the selection strategy. Experiments conducted on the ViBe algorithm show that our feature selection technique improves the segmentation results.

[more ▼]In the framework of the Interreg IVB project AMICE, hydraulic modelling of floods in the river Meuse was performed by coordinating existing models (Dewals et al. 2012a). The influence of climate change scenarios was incorporated indirectly in the simulations through a transnational hydrological scenario (Drogue et al. 2010; Dewals et al. 2013). For a “wet” future climate, this scenario assumes that the peak discharge Q100 of the 100-year flood would increase by 15 % for the time horizon 2021-2050 and by 30 % for the time horizon 2071-2100. However, the design discharge currently used for planning in the Netherlands is higher than those considered to date in the AMICE project. From this perspective, it becomes relevant to analyse flood scenarios corresponding to a peak discharge above Q100+30 %, referred to hereafter as an “extreme” flood. The aim of the study is to give an appreciation of the potential damping of one extreme flood scenario along the river Meuse between Ampsin (Belgium) and the Belgian-Dutch border (Figure 1). This analysis is based on the hydraulic model WOLF 2D (Erpicum et al. 2010) applied to a coarse grid with simplifications in the schematisation. The hydraulic model WOLF 2D has been already used in several studies to simulate floods (Ernst et al. 2010; Beckers et al. 2013, Bruwier et al. 2015, Detrembleur et al. 2015). The coarsening of the grid for simulating the extreme flood scenario is necessary to preserve the computational efficiency, since both the total flood duration and the inundation extents (hence the number of grid cells) increase considerably between the Q100 + 30 % scenario considered previously and the extreme scenario considered here.

[more ▼]In this paper, we evaluate a set of methods for combining features for cover song identification. We first create multiple classifiers based on global tempo, duration, loudness, beats and chroma average features, training a random forest for each feature. Subsequently, we evaluate standard combination rules for merging these single classifiers into a composite classifier based on global features. We further obtain two higher level classifiers based on chroma features: one based on comparing histograms of quantized chroma features, and a second one based on computing cross-correlations between sequences of chroma features, to account for temporal information. For combining the latter chroma-based classifiers with the composite classifier based on global features, we use standard rank aggregation methods adapted from the information retrieval literature. We evaluate performance with the Second Hand Song dataset, where we quantify performance using multiple statistics. We observe that each combination rule outperforms single methods in terms of the total number of identified queries. Experiments with rank aggregation me- thods show an increase of up to 23.5 % of the number of identified queries, compared to single classifiers.

[more ▼]In Europe, analysis of meteorological data shows that the average temperature has increased by ~1°C over the past hundred years (IPCC, 2013). Heat stress periods are thus expected to be more frequent even in temperate areas. The use of an automatic milking system (AMS) implies the need to stimulate cows’ traffic to the robot, especially with grazing cows. Describing how heat stress influenced cows’ traffic to the robot is the aim of this study. Grazing dairy cows milked by an automatic system (AMS) experienced heat stress (HS) periods, twice during the summer 2013 in July (J) and August (A). The daily temperature humidity index (THI) during these periods were higher than 75. Each HS period was compared with a “normal period”(N), presenting the same number of cows, similar lactation number, days in milk, distance to come back to the robot and an equal access to water. The first HS period of 5 days with a mean THI of 78.4 was chosen in J, and a second that lasted for 6 days in A with a THI value of 77.3. Heat stress periods were cut off with the same duration of days with no stress (N) and mean THI <70. Milk production, milkings and refusals to the robot during HS were compared with N periods. Milkings and refusals were significantly more numerous in HS periods in July (HS: 2.54 ± 0.11 vs N: 2.19 ± 0.08, 1.87 ± 0.20 vs 0.72 ± 0.16) but milk production dropped from 21.8 ±0.6 kg per cow and per day during N periods to 18.9 ± 0.8 kg in HS. In August, MY increased slightly during HS. This could be explained by less high ambient temperatures and decreased distance to walk inducing less energy expenditure. The increase in milkings and refusals to the robot during HS could be linked to water availability nearby the robot and confirmed previous findings (Lessire et al., 2014).

[more ▼]Background : Breast cancer is the most frequent cancer in women, affecting 8 women out of 100. With early detection and improved treatments, the number of deaths linked to this disease has declined. However, the disease and its treatments are at the origin of many undesirable side effects such as fatigue, anxiety, weight gain and sleep disorders. The objective of this study is to determine the psychological benefits of a multidisciplinary rehabilitation program among women treated for breast cancer (on average six months after the end of the adjuvant radiotherapy or chimiotherapy). Material and methods : 122 patients were included into a control group (n = 61) and a treated group (n = 61). All participants were submitted to evaluations before the beginning of the trial and after three months. These evaluations included different questionnaires exploring the quality of life, anxiety, depression and various functions and other symptoms related to cancer (EORTC QLQ-C30, EQ-5D, STAI, HADS) and functional assessments. The control group has received no intervention unlike the treated group that received a three-month rehabilitation including supervised physical training (90 min) with three times a week and various psycho-educational sessions (120 min) once a week. Results : After three months, the health status (quality of life) (p < 0,0001), the functional role (p = 0,031), emotional state (p < 0,0001) and physical (p = 0,0045), cognitive (p = 0,0027) and social functions (p = 0,0018) improve significantly in the treated group. This observation also applies to symptoms of fatigue (p < 0,0001), insomnia (p < 0,0001), pain (p = 0,002), dyspnea (p = 0,009), loss of appetite (p = 0,04), anxiety (p < 0,0001) and depression (p < 0,0001) as well as physical parameters obtained through functional assessments. In the control group, these improvements do not appear. Conclusions : This study shows the feasibility and psychological benefits of such a multidisciplinary oncological rehabilitation program in women after their treatments for breast cancer. Additional studies are needed to know the optimal time of beginning (during treatments or after them) and the optimal management time for this support.

[more ▼]The European Space Agency (ESA) is planning to launch in 2018 the PROBA3 Mission, designed to demonstrate the inorbit formation flying (FF) attitude capability of its two satellites and to observe the inner part of the visible solar corona as the main scientific objective. The solar corona will be observed thanks to the presence on the first satellite, facing the Sun, of an external occulter producing an artificial eclipse of the Sun disk. The second satellite will carry on the coronagraph telescope and the digital camera system in order to perform imaging of the inner part of the corona in visible polarized light, from 1.08 Rsun up to about 3 Rsun. One of the main metrological subsystems used to control and to maintain the relative (i.e. between the two satellites) and absolute (i.e. with respect to the Sun) FF attitude is the Shadow Position Sensor (SPS) assembly. It is composed of eight micro arrays of silicon photomultipliers (SiPMs) able to measure with the required sensitivity and dynamic range the penumbral light intensity on the Coronagraph entrance pupil. In the following of the present paper we describe the overall SPS subsystem and its readout electronics with respect to the capability to satisfy the mission requirements, from the light conversion process on board the silicon-based SPS devices up to the digital signal readout and sampling.

[more ▼]PROBA-3/ASPIICS is a formation Flying coronagraph selected by ESA and currently in its C/D phase. It is constituted by two spacecrafts (OSC, Occulter SpaceCraft, carrying the occulter, diameter 142 cm, and CSC, Coronagraph SpaceCraft, with the telescope) separated by ~144 m, kept in strict alignment by means of an active custom system. The alignment active system most critical components are the Shadow Positioning Sensors (SPS), a series of Si-PM (Silicon Photomultiplier) measuring the penumbra generated by the occulter. The arrangement of the SPSs around the telescope entrance aperture is defined as a trade-off between mechanical constraints and maximum sensitivity to misalignments. The signal detected by the SPSs can be approximately simulated with a geometrical analysis based on the variation of the penumbra generated by the external occulter. The stray light generated by the diffraction from the external occulter may affect the SPSs signal. It is mandatory to carefully evaluate its level in order to refine the active alignment adjustment algorithm. This work is dedicated to the description of the preliminary investigation performed in order to evaluate the impact of the diffraction on the SPSs signal.

[more ▼]The “sonic region” of the Sun corona remains extremely difficult to observe with spatial resolution and sensitivity sufficient to understand the fine scale phenomena that govern the quiescent solar corona, as well as phenomena that lead to coronal mass ejections (CMEs), which influence space weather. Improvement on this front requires eclipse-like conditions over long observation times. The space-borne coronagraphs flown so far provided a continuous coverage of the external parts of the corona but their over-occulting system did not permit to analyse the part of the white-light corona where the main coronal mass is concentrated. The proposed PROBA-3 Coronagraph System, also known as ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun), with its novel design, will be the first space coronagraph to cover the range of radial distances between ~1.15 and 3 solar radii where the magnetic field plays a crucial role in the coronal dynamics, thus providing continuous observational conditions very close to those during a total solar eclipse. PROBA-3 is first a mission devoted to the in-orbit demonstration of precise formation flying techniques and technologies for future European missions, which will fly ASPIICS as primary payload. The instrument is distributed over two satellites flying in formation (approx. 150m apart) to form a giant coronagraph capable of producing a nearly perfect eclipse allowing observing the sun corona closer to the rim than ever before. The coronagraph instrument is developed by a large European consortium including about 20 partners from 7 countries under the auspices of the European Space Agency. This paper is reviewing the recent improvements and design updates of the ASPIICS instrument as it is stepping into the detailed design phase.

[more ▼]In the framework of development of ASPIICS (Association of Spacecraft for Polarimetric and Imaging Investigation of the Corona of the Sun), the Centre Spatial de Liege is responsible of the optical design of the coronagraph and the optics will be manufactured by TOPTEC. The particularity of this coronagraph is to have an external occulter located 150 m ahead of the first imaging lens. This external occulter is re-imaged on an internal occulter which function is - as in a classical externally occulted Lyot coronagraph - to block the sun light diffracted by the external occulter and to reduce the straylight on the detector. The selection of this configuration is driven by the requirement to observe the corona as close as possible to the solar limb (i.e. 1 RSun) without imaging the limb itself. A requirement of 1.08 RSun is specified at optical design level to grant 1.2 Rsun at instrument level. The coronograph instrument is designed to have a field of view of 1.6° x 1.6° with a resolution of less than 6 arcsec. Its performances are limited by diffraction in a 530 – 590 nm wavelength range.

[more ▼]In recent years, ESA has assessed several mission involving formation flying (FF). The great interest in this topics is mainly driven by the need for moving from ground to space the location of next generation astronomical telescopes overcoming most of the critical problems, as example the construction of huge baselines for interferometry. In this scenario, metrology systems play a critical role. PROBA3 is an ESA technology mission devoted to in-orbit demonstration of the FF technique, with two satellites, an occulter and a main satellite housing a coronagraph named ASPIICS, kept at an average inter-distance by about 144m, with micron scale accuracy. The guiding proposal is to test several metrology solution for spacecraft alignment, with the important scientific return of having observation of Corona at never reached before angular field. The Shadow Position Sensors (SPS), and the Optical Position Emitters Sensors (OPSE) are two of the systems used for FF fine tracking. The SPS are finalized to monitor the position of the two spacecraft with respect to the Sun and are discussed in dedicated papers presented in this conference. The OPSE will monitor the relative position of the two satellites and consists of 3 emitters positioned on the rear surface of the occulter, that will be observed by the coronagraph itself. By following the evolution of the emitters images at the focal plane the alignment of the two spacecrafts is retrieved via dedicated centroiding algoritm. We present an overview of the OPSE system and of the centroiding approach.

[more ▼]PROBA3 is an ESA technology mission devoted to in-orbit demonstration of the formation flight (FF) technique, with two satellites kept at an average inter-distance by about 144 m. The ASPIICS instrument on-board PROBA3 will be the first ever space-based coronagraph working on one satellite and having the external occulter located on the second satellite, thus allowing observations of the inner solar corona with unprecedented reduction of stray light. During the observational periods, the FF configuration will be maintained with very high precision and two different techniques will be implemented: the use of Shadow Positioning Sensors (SPS) located on the Coronagraph Spacecraft (diodes measuring the penumbral light intensity on the entrance pupil plane) and the use of Occulter Position Sensor LEDs (OPSE) located on the back side of the Occulter Spacecraft. This paper will review the main instrumental requirements on the SPS needed to determine the 3-dimensional relative positioning of the two PROBA3 satellites with the high precision and frequency.

[more ▼]The Large Binocular Telescope Interferometer (LBTI) is a strategic instrument of the LBT designed for high-sensitivity, high-contrast, and high-resolution infrared (1.5-13 $\mu$m) imaging of nearby planetary systems. To carry out a wide range of high-spatial resolution observations, it can combine the two AO-corrected 8.4-m apertures of the LBT in various ways including direct (non-interferometric) imaging, coronagraphy (APP and AGPM), Fizeau imaging, non-redundant aperture masking, and nulling interferometry. It also has broadband, narrowband, and spectrally dispersed capabilities. In this paper, we review the performance of these modes in terms of exoplanet science capabilities and describe recent instrumental milestones such as first-light Fizeau images (with the angular resolution of an equivalent 22.8-m telescope) and deep interferometric nulling observations.

[more ▼]We present methods for optimizing pupil and focal plane optical elements that improve the performance of vortex coronagraphs on telescopes with obstructed or segmented apertures. Phase-only and complex masks are designed for the entrance pupil, focal plane, and the plane of the Lyot stop. Optimal masks are obtained using both analytical and numerical methods. The latter makes use of an iterative error reduction algorithm to calculate "correcting" optics that mitigate unwanted diffraction from aperture obstructions. We analyze the achieved performance in terms of starlight suppression, contrast, off-axis image quality, and chromatic dependence. Manufacturing considerations and sensitivity to aberrations are also discussed. This work provides a path to joint optimization of multiple coronagraph planes to maximize sensitivity to exoplanets and other faint companions.

[more ▼]The Annular Groove Phase Mask (AGPM) is a vectorial vortex phase mask. It acts as a half-wave plate with a radial fast axis orientation operating in the mid infrared domain. When placed at the focus of a telescope element provides a continuous helical phase ramp for an on axis sources, which creates the orbital angular momentum. Thanks to that phase, the intensity of the central source is canceled by a down-stream pupil stop, while the off axis sources are not affected. However due to experimental conditions the nulling is hardly perfect. To improve the null, a Mach-Zehnder interferometer containing Dove prisms differently oriented can be proposed to sort out light based on its orbital angular momentum (OAM). Thanks to the differential rotation of the beam, a π phase shift is achieved for the on axis light affected by a non zero OAM. Therefore the contrast between the star and its faint companion is enhanced. Nevertheless, due the Dove prisms birefringence, the performance of the interferometer is relatively poor. To solve this problem, we propose to add a birefringent wave-plate in each arm to compensate this birefringence. In this paper, we will develop the mathematical model of the wave front using the Jones formalism. The performance of the interferometer is at first computed for the simple version without the birefringent plate. Then the effect of the birefringent plate is be mathematically described and the performance is re-computed.

[more ▼]Screw-type volumetric expanders have been demonstrated to be a suitable technology for organic Rankine cycle (ORC) systems because of higher overall effectiveness and good part-load behaviour over other positive displacement machines. An 11 kWe single-screw expander (SSE) adapted from an air compressor has been tested in an ORC test-rig operating with R245fa as working fluid. A total of 60 steady-steady points have been obtained at four different rotational speeds of the expander in the range between 2000 rpm and 3300 rpm. The maximum electrical power output and overall isentropic effectiveness measured were 7.3 kW and 51.9%, respectively. In this paper, a comparison between two low-order models is proposed in terms of accuracy of the predictions, the robustness of the model and the computational time. The first model is the Pacejka equation-based model and the second is a semi-empirical model derived from a well-known scroll expander model and modified to include the geometric aspects of a single screw expander. The models have been calibrated with the available steady-state measurement points by identifying the proper parameters. 1. [less ▲]Detailed reference viewed: 23 (2 ULg) 1.

[more ▼]Straw-bale use in buildings may be an interesting way to decrease our energy needs and our impact on the environment. Moreover, it fosters a local economy and the creation of new jobs in the building industry. Combined with earth materials and other well-selected materials and systems, it allows creative designers to integrate highly efficient, low-tech and reusable envelopes in comfortable and healthy places. The present paper summarizes the results of a four year R&D program aiming to improve and promote the use of straw bale in buildings and also to remove uncertainties concerning this use. Three main aspects are pinpointed and discussed: hygrothermal transfer and storage in straw-bale walls, regulation of indoor conditions and environmental impact in the long term. These three topics were submitted to European experts (France, England and Germany) in order to discuss a cross-comparison of results obtained on a larger scale. The paper shows that straw-bale use in buildings is a relevant and innovative solution in facing one of the major challenges of today and tomorrow: "How to build/transform comfortable and affordable buildings with local resources and with a positive impact on the environment?".

[more ▼]Alluvial aquifers are generally composed of several facies with complex architectures and interconnections depending on the fluvial system. In this context, electrical resistivity tomography (ERT) may provide important information on the spatial distribution of hydrogeological parameters. However, ERT inversion introduces some bias in the resulting resistivity distribution due to regularization and resolution issues. In this study, we refine ERT inversions by incorporating prior information in order to improve the identification of facies through a probabilistic relationship derived from collocated measurements. We then analyze with synthetic cases the effect of spatially varying sensitivity on the probabilistic relationship. As expected, when sensitivity decreases, the distributions of resistivity for the different facies tend to be superimposed. A mean distribution thus overestimates the ability of surface ERT to discriminate hydrofacies in depth.

[more ▼]Community resilience to extreme events is an issue of increasing concern in our interconnected and urbanized societies. This work provides a framework to evaluate the response of a community of buildings to fire following earthquake, a potentially highly destructive cascading multi-hazard event. In a previous part of the work, a model has been developed to predict the probability of ignition in a building due to an earthquake. Given an ignition in a building, the probability of the structure exceeding certain limit states must be evaluated in order to quantify the expected damage loss. Adopting an approach similar to that used in seismic engineering, fragility functions can be developed for structures subjected to fire. The methodology is described here for a prototype nine-story steel frame building. In developing the fragility functions, uncertainties in the fire model, the heat transfer model and the thermo-mechanical response are considered. In addition several fire scenarios at different locations in the building are studied. The demand on and capacity of the system are assessed probabilistically in terms of critical temperature. The developed fire fragility functions yield the probability of exceedance of predefined damage states as a function of the fire load in the building. Future works will aim to implement fire fragility functions into a GIS based risk assessment software platform for assessment of the expected risk and cost associated with fire following earthquake for a community of buildings.

[more ▼]methodAbstract.The interaction between lattice dislocations and Coherent Twin Boundary Σ3 {111} of copper has been studied using Quasi-Continuum method. The coherent twin boundary provides high barrier to slip transmission. The dislocation pile-up modifies the stress field at its intersection with the grain boundary. A different reaction process compared with the case of single dislocations is noticed. One observes the nucleation of a Lomer-type dislocation with Burgers vector of ½ <110 > and its glide onthe (100) cube plane in the adjacent grain. This phenomenon has been observed with Transmission Electron Microscopy at room temperature and in other Molecular Dynamics simulations. We also show a novel interaction mechanism between Lomer-type dislocation and Coherent Twin Boundary. This interactionprocess leaves a dislocation with a Burgers vector coincident with the complete lattice shift of the Coherent Twin Boundary. Quantitative estimation of critical stress for various transmission phenomena is performed by using virial stress.

This X-ray emission probes the most energetic phenomena occurring in the circumstellar environment of these stars, and provides precious insight on magnetic phenomena or hydrodynamic shocks. Owing to its unprecedented capabilities, Athena will open up an entirely new window on these phenomena. Athena will not only allow us to study many more objects with an unprecedented spectral resolution, but will also pioneer the study of the dynamics of these objects via time-resolved high-resolution spectroscopy. These studies will lead to a deeper understanding of yet poorly understood processes which have profound impact in star formation and evolution, including at earlier times in the Universe.

We present the confirmation, based on Spitzer observations, that the super-Earth HD 97658 b transits its host star. HD 97658 is a low-mass (M*=0.77+-0.05 Msun) K1 dwarf, as determined from the Hipparcos parallax and stellar evolution modeling. To constrain the planet parameters, we carry out Bayesian global analyses of Keck-HIRES radial velocities, and MOST and Spitzer photometry. HD 97658 b is a massive (Mp=7.55 +0.83,-0.79 Mearth) and large (Rp = 2.247 +0.098,-0.095 Rearth at 4.5 microns) super-Earth. We investigate the possible internal compositions for HD 97658 b. Our results indicate a large rocky component, by at least 60% by mass, and very little H-He components, at most 2% by mass. We also discuss how future asteroseismic observations can improve the knowledge of the HD 97658 system, in particular by constraining its age.

[more ▼]Intoduction : De nos jours, la majorité des patients consultent un dentiste pour des problèmes dentaires stricto senso et fort peu pour des pathologies liées au parodonte. Ce dernier est pourtant leur structure d’ancrage permettant le maintien des dents et donc de l’appareil manducateur. La présence d’un saignement gingival au brossage quotidien, étant la plupart du temps non douloureux, ne déclenche souvent aucune inquiétude ni demande de consultation. Il s'agit pourtant d'un des signes cliniques les plus évidents des parodontopathies qui affectent, à des degrés divers, pratiquement 90% de la population en France dans toutes les tranches d'âge et cause la perte de 30 à 40% des dents. Objectif : Le parodonte représente un des points fragiles de notre corps permettant facilement l’entrée de bactéries dans la circulation sanguine et expliquant une relation entre la maladie parodontale et certaines maladies systémiques. Qu’en est-t-il des tendinopathies? Cette étude a pour objectif de mettre en évidence les relations entre l’hygiène bucco-dentaire et ses répercussions sur les tendinopathies. Matériel & méthode : Soixante-quatre sportifs réguliers ont participé à un examen parodontal complet au cours duquel les paramètres cliniques suivants ont été enregistrés: indices de plaque (PI), indice gingival (GI) et indice de saignement papillaire (PBI). Les athlètes ont été répartis en trois groupes en fonction de leur état de santé : « athlètes non blessés » (ANB), « athlètes blessés » (AB) et « athlètes régulièrement blessés » (ARB). Résultats : En comparant les groupes ANB et AB on remarque une différence significative entre les trois valeurs enregistrées (IP : p=0.023 ; IG : p<0.0001 ; PBI : p<0.0001). Le groupe ARB ne montre pas de différences significatives avec les deux autre groupes. Discussion et Conclusion : Notre étude montre une relation entre les parodontopathies et les tendinopathies mais le modèle ne permet pas à déterminer l’origine ni l’importance de cette relation. Il est recommandé aux athlètes de prêter suffisaient attention à leur hygiène de vie générale et de ne pas négliger leur hygiène dentaire.

La tendinopathie patellaire proximale est une des tendinopathies les plus réfractaires au traitement conservateur et peut affecter la qualité de vie en limitant les activités sportives qu'elles soient récréationnelles ou professionnelles. Objectifs : L’objectif de cette étude est d’évaluer les effets à long terme du PRP pour traiter les tendinopathies patellaires proximales et éventuellement d’en identifier des facteurs de bon pronostic. Matériel et méthodes: 25 tendinopathies patellaires proximales ont été traités par PRP et ont été suivie à plus d’un an (dont 9 sujets sont suivi jusque 48 mois post-infiltration). Les patients sont évalués selon les questionnaires VISA-P, IKDC et un questionnaire reprenant leurs habitudes. Les scores VISA-P et IKDC sont croisés avec le troisième questionnaire afin d’obtenir des moyennes en rapport avec les réponses de ce dernier. Résultats : Aucun patient n’a été traité par chirurgie après l’infiltration. L’évolution des patients a tendance à être toujours positive jusqu’à 48 mois. Les facteurs semblant être bénéfiques sur l’évolution des patients sont : l’activité sportive à une fréquence de six à huit heures de sport par semaine, la réalisation d’exercices excentriques à domicile, une hydratation de plus d’un litre et demi par jour, un échauffement de plus de dix minutes ainsi que l’âge des patients (<30 ans). Conclusion : Le traitement d’une tendinopathie patellaire proximale par infiltration de PRP est efficace à long terme (jusque 4 ans). La réalisation d’exercices excentriques réguliers semble nécessaire et permet d’observer la poursuite de l’amélioration clinique des patients.

Elles représentent près de 20% des troubles musculo-squelettiques et plus de 30% des consultations en médecine générale et en médecine sportive. Ces tendinopathies peuvent être rebelles aux traitements conservateurs, raison pour laquelle de nouveaux traitements sont développés parmi lesquels figurent les infiltrations de plasma riche en plaquettes (PRP). L’objectif de notre étude est d’évaluer l’effet d’une injection de PRP suivie d’un protocole de rééducation standardisé chez des patients présentant différentes tendinopathies : épicondylites, tendinopathies du moyen glutéus, patellaires, calcanéennes et fasciites plantaires. Enfin, nous souhaitons mettre en évidence des facteurs biologiques de bon pronostic suite à un traitement par PRP. Matériels et méthodes : 51 patients atteints de différentes tendinopathies, réfractaires aux traitements de kinésithérapie classique depuis au moins 3 mois, ont reçu une injection de PRP sous contrôle échographique sans anesthésie locale. Par la suite, ils ont bénéficié d’une rééducation excentrique standardisée. Aux trois temps de l’étude (pré-injection, 6 semaines et 12 semaines), ils ont reçu une évaluation algo-fonctionnelle (EVA, PRTEE, HOOS, VISA-P, VISA-A, FAAM) en fonction de la localisation de la tendinopathie et une évaluation de la douleur par un algomètre de pression. Résultats : Les résultats montrent d’une manière générale une amélioration significative de l’EVA (p=0,01) après 3 mois de suivi et une amélioration de l’algomètre de pression entre 6 et 12 semaines (p=0,05). Pour les épicondylites, les améliorations sont significatives pour l’EVA (p=0,017) et le PRTEE (p=0,0036) au terme de l’étude. Les tendinopathies du moyen glutéus, patellaires et les fasciites plantaires montrent également une amélioration clinique mais non significative (nombre de sujets trop faible). Concernant les tendinopathies d’Achille, l’EVA (p<0.001) et le VISA-A (p=0,018) évoluent de manière significative après les 6 premières semaines. Aucune relation n’a été mise en évidence entre l’évolution de l’EVA et de l’algomètre de pression et les paramètres biologiques. Conclusions : Une injection de PRP couplée à un programme de rééducation excentrique présente des effets positifs au niveau de la symptomatologie douloureuse et la fonctionnalité pour les épicondylites et les tendinopathies d’Achille. Malgré l’absence de résultats significatifs, la tendance est à l’amélioration clinique concerne également les tendinopathies du moyen glutéal, patellaires et les fasciites plantaires.

[more ▼]The COST Action TU1401 ‘Renewable Energy and Landscape Quality’ ('RELY') encourages Short Term Scientific Missions (STSMs). This Action investigates “the inter‐relationships between renewable energy production and landscape quality, and the role of public participation for the acceptance of renewable energy systems”. STSMs are exchange visits from five working days until three months that are aiming to strengthen the existing networks by allowing individual scientists to go to an institution or laboratory in other COST country to foster collaboration and contribute to the scientific objectives of the COST Action. Each year of the COST Action TU1401, there are up to six STSMs to be awarded. The financial support is a contribution to the costs of a STSM. A grant (maximum 2500€ depending on the duration of the stay) covers travel and subsistence. We invite researchers, especially early stage researchers, to participate in a STSM. The selection of STSM applicants is based on the scientific scope of the STSM application that must be in line with the Cost Action TU1401 objectives. This short communication aims to inform of the next calls and presents the result of the 2015 call.

[more ▼]The quest for the “best” background subtraction technique is ongoing. Despite that a considerable effort has been undertaken to develop flexible and efficient methods, some elementary questions are still unanswered. One of them is the existence of an intrinsic upper bound to the performance. In fact, data are affected by noise, and therefore it is illusory to believe that it is possible to achieve a perfect segmentation. This paper aims at exploring some intrinsic limitations of the principle of background subtraction. The purpose consists in studying the impact of several limiting factors separately. One of our conclusions is that even if an algorithm would be able to calculate a perfect background image, it is not sufficient to achieve a perfect segmentation with background subtraction, due to other intrinsic limitations.

[more ▼]Stroke Volume (SV) measurements are essential for evaluating patient hemodynamic status and response to therapy. However, current methods for monitoring SV require either invasive or non- invasive additional measurements. This study investigates the relationship between SV and Pulse Wave Velocity (PWV) to examine whether the value of PWV can capture the changes in SV. The analysis was performed using data from six porcine experiments (N=6 Pietrain Pigs, 20-29 kg) in which left ventricular volume, aortic arc pressure, and descending aortic pressure waveforms were measured simultaneously. From the measured data, correlation coefficients were determined between absolute value of aortic PWV, SV and trend value ‘PWV – mean PWV’, ‘SV – mean SV’ during periods when changes in SV were induced from preload changes, as well as infusion of dobutamine. The results showed good correlation (r = 0.59) for trend value, however, the correlation coefficient were poor with r = 0.028 for absolute value across all pigs. The analysis showed that value of PWV is reliable for capturing trend value of SV in preload changes. However, it is unreliable for capturing absolute value of SV or changes in SV made from dobutamine.
