Abstract

session Fr1: Defects and Device Structures (027); International audience; Extended electrically active defects have been investigated in Short Wave InfraRed (SWIR) HgCdTe n on p photodiodes, using the Deep Level Transient Spectroscopy (DLTS) technique. Three localized defects have been found in the dislocations’ core or in their close environment. DLTS studies have also been performed before and after indentation, a technique which generates dislocations in the material. DLTS spectra are discussed and dislocations generated by indentation have been found to be electrically active only after annealing.

Abstract

International audience; Informal Learning in the Workplace (ILW) is ensured by the everyday work activities in which workers are engaged. It accounts for over 75 per cent of learning in the workplace. Enterprise Social Media (ESM) are increasingly used as informal learning environments. According to the results of an implementation we have conducted in real context, we show that ESM are appropriate to promote ILW. Nevertheless, social aspects must be reconsidered to address users’ needs regarding content and access, quality information indicators, moderation and control.

Abstract

IV 2017 - IEEE Intelligent Vehicles Symposium, Redondo Beach, Los Angeles, ETATS-UNIS, 11-/06/2017 - 14/06/2017; For several years, researches dedicated to autonomous driving are growing and a great number of applications and algorithms have been developed for embedded ADAS. In a part of these very critical applications, the tracking of the road's obstacles is one of the key elements. The tracking is built around a stage of measurement to track association. It consists in assessing the similarity between two sets of multi-dimensional state vectors characterizing the track and the measurement. For this application, but not only, we propose in this work a multi-criteria similarity operator based on Belief Theory allowing to take into account uncertainties and imperfections on the data. Partial data availability, conflict and ambiguities between state vectors are managed. The output of this operator provides not only the similarity but also the dissimilarity level, the amount of conflict and ambiguity. This operator is applied to relevant use-cases to highlight its benefits over the standard similarity operators.

Abstract

International audience; In this paper a novel optimal control strategy for energy management of an off-grid hybrid Stirling engine/Supercapacitor power plant is presented based on preliminary results proposed in \cite{Rahmani2013}. An implementation of the control strategy is performed on a real time target that drives a dedicated testbed with a DC machine reproducing the functioning of the thermodynamic Stirling Engine. The DC machine is linked to a Permanent Magnet Synchronous Generator (PMSG) connected to an AC load through an appropriate controlled Power electronics and an energy storage device which is a supercapacitor. The performances of the developed control Strategy are then assessed through experimental results on the testbed.

Abstract

This paper presents an approach developed to study the behavior of the masonry vaulted tunnels in order to evaluate the serviceability state and failure load. An appropriate homogenization technique is used to simulate the global anisotropic behavior across the vault. The model takes into account isotropic damage in each component of the masonry and the variations of the directions of anisotropy in case of a vault. A set of comparisons with experimental tests allowed the validation of the proposed approach. Failure loads and deformation states are correctly assessed. The present model was programmed in the finite element code CESAR-LCPC.; Cet article présente une approche développée pour étudier le comportement des voutes de tunnels en maçonnerie pour évaluer leurs états limites de service et ultimes. Une technique d'homogénéisation appropriée est utilisée pour simuler le comportement anisotrope global de la voute. Le modèle prend en compte l'endommagement de chaque composant de la maçonnerie et les variations des directions d'anisotropie dans le cas d'une voute. Un ensemble de comparaisons avec des résultats expérimentaux permet de valider l'approche proposée. Les charges limites et les déformations sont correctement reproduites. Le modèle a été introduit dans le code de calcul par éléments finis CESAR-LCPC.

Abstract

S–N curve is the main tool to analyze and predict fatigue lifetime of a metallic material, component or structure. But, standard models based on mechanic of rupture theory or standard probabilistic models for analyzing S–N curves could not fit S–N curve on the whole range of cycles without microstructure information. This information is obtained from costly fractography investigation rarely available in the framework of industrial production. On the other hand, statistical models for fatigue lifetime do not need microstructure information but they could not be used to service life predictions because they have no material interpretation. Moreover, fatigue test results are widely scattered, especially for High Cycle Fatigue region where split S–N curves appear. This is the motivation to propose a new probabilistic model. This model is a specific mixture model based on a fracture mechanic approach, and does not require microstructure information. It makes use of the fact that the fatigue lifetime can be regarded as the sum of the crack initiation and propagation lifes. The model parameters are estimated with an EM algorithm for which the Maximisation step combines Newton–Raphson optimization method and Monte Carlo integrations. The resulting model provides a parsimonious representation of S–N curves with parameters easily interpreted by mechanic or material engineers. This model has been applied to simulated and real fatigue test data sets. These numerical experiments highlight its ability to produce a good fit of the S–N curves on the whole range of cycles. We must also notice that this model is proposed for large database ( > 50 data).

Abstract

International audience; In this paper, a complete control architecture is proposed for the voltage conditioning stage of a hybrid power generation system composed of a Stirling Engine coupled with a supercapacitor. Such a solar energy-based generation system aims at providing electricity to off-grid regions. The novelty of the proposed architecture is that it completely handles constraints on all the state variables of the electric stage while providing near to optimal performances in terms of settling time. The derivation of the control law enables a deep understanding of the main issues involved in the success of the closed-loop control. Moreover, the resulting feedback laws are real-time compatible and are given in a complete explicit form.

Abstract

Erratum publié en novembre 2015, Volume 95, Issue 6, pp 919-920 - Clé UT 000364974900008 - http://link.springer.com/article/10.1007%2Fs13594-015-0221-x; Somatic cells are an important component naturally present in milk, and somatic cell count is used as an indicator of udder health and milk quality. The role of somatic cells in dairy processes and products is ill-defined in most studies because the role of these cells combines also the concomitance of physicochemical modifications of milk, bacterial count, and the udder inflammation in the presence of high somatic cell count. The aim of this review is to focus on the role of somatic cells themselves and of endogenous enzymes from somatic cells in milk, in dairy transformation processes, and in characteristics of final products overcoming biases due to other factors. The immune function of somatic cells in the udder defense and their protective role in milk will be primarily considered. Different characteristics of milk induced by various somatic cell counts, types, and their endogenous enzymes influencing directly the technological properties of milk and the final quality of dairy products will be discussed as well. By comparing methods used in other studies and eliminating biases due to other factors not considered in these studies, a new approach has been suggested to evaluate the effective role of somatic cells on dairy processes and products. In addition, this new approach allows the characterization of somatic cells and their endogenous enzymes and, in future research, will allow the clarification of mechanisms involved in the release of these components from somatic cells during dairy processes, particularly in cheese technologies.

Abstract

International audience; We compared the powers of the likelihood ratio test (LRT) and the Pearson correlation test (CT) from empirical Bayes estimates (EBEs) for various designs and shrinkages in the context of nonlinear mixed-effect modeling. Clinical trial simulation was performed with a simple pharmacokinetic model with various weight (WT) effects on volume (V). Data sets were analyzed with NONMEM 7.2 using first-order conditional estimation with interaction and stochastic approximation expectation maximization algorithms. The powers of LRT and CT in detecting the link between individual WT and V or clearance were computed to explore hidden or induced correlations, respectively. Although the different designs and variabilities could be related to the large shrinkage of the EBEs, type 1 errors and powers were similar in LRT and CT in all cases. Power was mostly influenced by covariate effect size and, to a lesser extent, by the informativeness of the design. Further studies with more models are needed.

Abstract

International audience; This paper concerns the integration of RFID (Radio Frequency IDentification) technologies in helicopters. A global RFID system, including RFID tags (passive, battery assisted and active), reading modules and data concentrator, will be embedded in helicopters. Such an integration requires a positioning model, which must consider technological choices of the on-board components. The proposed approach combines an optimization model and a physical model to determine an optimal covering of each tag by at least one reading module. This covering is based on radio wave propagation. The optimization model is derived from a location model with specific constraints. Experimental results validate the approach in an industrial context.

Abstract

International audience; Nuclear steam generators are subject to clogging of their internal parts which causes safety issues. Diagnosis methodologies are needed to optimize maintenance operations. Clogging alters the dynamic behaviour of steam generators and particularly the response of the wide range level (WRL - a pressure measurement) to power transients. A numerical model of this phenomenon has previously been developed. Its input variables describe the spatial distribution of clogging and its output is a discretization of the WRL dynamic response. The objective of the present study is to characterize the information about the clogging state of a steam generator that can be inferred from the observation of its WRL response. A methodology based on several statistical techniques is implemented to answer that question. Principal component analysis reveals that clogging alters the WRL response mainly in two distinct ways. Accordingly, the output can be summarized into a vector of dimension 2. A sensitivity analysis is carried out to rank the input variables by magnitude of influence. It has shown that they can be divided into two groups corresponding to the two sides of the steam generator. Finally, sliced inverse regression is used to reduce the input dimension from 16 to 2. A sampling issue that arises when the input dimension is high is addressed. The simplification of the original problem yields a diagnosis methodology based on response surface techniques.

Abstract

International audience; The paper contributes to No-Reference video quality assessment of broadcasted HD video over IP networks and DVB. In this work we have enhanced our bottom-up spatio-temporal saliency map model by considering semantics of the visual scene. Thus we propose a new saliency map model based on face detection that we called semantic saliency map. A new fusion method has been proposed to merge the bottom-up saliency maps with the semantic saliency map. We show that our NR metric WMBER weighted by the spatio-temporal-semantic saliency map provides higher results then the WMBER weighted by the bottom-up spatio-temporal saliency map. Tests are performed on two H.264/AVC video databases for video quality assessment over lossy networks.

Abstract

International audience; This paper presents an object tracking system. Our goal is to create a real-time object tracker that can handle occlusions, track multiple objects that are rigid or deformable, and on indoor or outdoor sequences. This system is composed of two main modules: motion detection and object tracking. Motion detection is achieved using an improved Gaussian mixture model. Based on multiple hypothesis of object appearance, tracking is achieved on various levels. The core of this module uses regions local and global information to match these regions over the frame sequence. Then higher level instances are used to handle uncertainty, such as missmatches, objects disappearance, and occlusions. Finally, merges and splits are detected for further occlusions detection.

Abstract

International audience; This paper contributes to objective video quality assessment of broadcasted HDTV content without reference. In this context we present a new No-Reference video quality metric taking into account the behavior of Human Visual System. This new metric called WMBER is based on macro-blocks error detection weighted by saliency maps computed at the decoder side. Moreover, both macro-block error detection and saliency maps processing require only partial decoding allowing real-time performance. A subjective experiment has been carried out to evaluate the performances of the proposed metric. The results are compared to the Full Reference metric MSE. The evaluation of the results shows that the proposed method provides a very good prediction of subjective measures.

Abstract

International audience; Human vision system is very complex and has been studied for many years specifically for purposes of efficient encoding of visual, e.g. video content from digital TV. There have been physiological and psychological evidences which indicate that viewers do not pay equal attention to all exposed visual information, but only focus on certain areas known as focus of attention (FOA) or saliency regions. In this work, we propose a novel based objective quality assessment metric, for assessing the perceptual quality of decoded video sequences affected by transmission errors and packed loses. The proposed method weights the Mean Square Error (MSE), Weighted-MSE (WMSE), according to the calculated saliency map at each pixel. Our method was validated trough subjective quality experiments.

Abstract

This paper presents a computer vision system that analyzes a scene, recognizes human behavior, and produces a semantic interpretation of the recognized behavior. Scene analysis consists of detecting motion and tracking detected objects. Then, the system detects events that define the current behavior of a person. Once behaviors are classified the system recognizes various predefined scenarios. Finally sentences are generated to describe each person's action in the scene. Our research is developed in order to build a realtime application that recognizes human behaviors while shopping. In particular, the system detects customer interests and interactions with various products of a point of purchase.

Abstract

International audience; When people gaze at real scenes, their visual attention is driven both by a set of bottom-up processes coming from the signal properties of the scene and also from top-down effects such as the task, the affective state, prior knowledge, or the semantic context. The context of this study is an assessment of manufactured objects (here car cab interior). From this dedicated context, this work describes a set of methods to analyze the eye-movements during the visual scene evaluation. But these methods can be adapted to more general contexts. We define a statistical model to explain the eye fixations measured experimentally by eye-tracking even when the ratio signal/noise is bad or lacking of raw data. One of the novelties of the approach is to use complementary experimental data obtained with the "Bubbles" paradigm. The proposed model is an additive mixture of several a priori spatial density distributions of factors guiding visual attention. The "Bubbles" paradigm is adapted here to reveal the semantic density distribution which represents here the cumulative effects of the top-down factors. Then, the contribution of each factor is compared depending on the product and on the task, in order to highlight the properties of the visual attention and the cognitive activity in each situation

Abstract

International audience; The deployment of IEC61850 standard in the world of substation automation system brings to the use of specific strategies for architecture testing. To validate IEC61850 architecture, the first step consists in validating the conformity of the object modeling and services implementation inside devices. The second step consists in validating IEC61850 applications compliance according to the project specifications. A part of the architecture can of course be tested "physically"; however in the design phase or when the actual architecture cannot be checked directly, modeling is helpful. In our research study we propose a co-simulation approach based on several components allowing the realization of advanced tests. This paper describes the need and the design implementation of software and hardware in the loop components as well as the object modeling concept of IED models.

Abstract

International audience; Due to the required memory space and computing time, temporal processing is rarely used even in video processing. However, when the temporal aspect of a compression noise is major, it cannot be treated spatially only. The following article presents an example of such a noise: the mosquito noise. The equally spatial and temporal nature of the mosquito artifact is first explained through its definition. It is followed by the different ways already used to treat it. A spatio-temporal and compression-independent mosquito noise corrector is then introduced. Finally, the interest of a temporal corrector over purely spatial ones is shown through tests results.

Abstract

6 pages; International audience; The testing of architectures is nowadays a critical issue for Substation Automation System world. Various aspects, related to the IEC61850 requirements, should be tested and checked in order to validate architecture. The first aspect consists in validating the conformity of the IEC61850 implementation inside devices according to the standards requirements. The second aspect consists in validating IEC61850 applications compliance according to the predefined functional specifications. Some devices and parts of the architecture can of course be tested "physically"; but in the design phase or when the actual architecture cannot be checked directly, modeling is helpful. In our research study we propose a co-simulation approach based on several components allowing the realization of substation automation system advanced tests. This paper describes the importance and the design implementation of hardware in the loop component which allows the combination of real and virtual devices.
