Scene-based noise reduction on a smart camera

2012

International audience; Raw output data from CMOS image sensors tends to exhibit significant noise called Fixed-Pattern Noise (FPN) due to on-die variations between pixel photodetectors. FPN is often corrected by subtracting its value, estimated through calibration, from the sensor's raw signal. This paper introduces an on-line scene-based technique for an improved FPN compensation which does not rely on calibration, and hence is more robust to the dynamic changes in the FPN which may occur slowly over time. Development has been done with a special emphasis on real-time hardware implementation on a FPGA-based smart camera. Experimental results on different scenes are depicted showing that t…

La compensation écologique d’après la loi biodiversité 

2016

La compensation écologique d'après la loi « biodiversité » Mal nécessaire, la compensation écologique cristallise des enjeux forts de société, laquelle reste tiraillée entre aspiration au développement économique et préservation des écosystèmes. Jusqu'alors éclatée dans diverses réglementations et très imparfaitement mise en œuvre, la séquence « éviter, réduire, compenser » est systématisée par la loi pour la reconquête de la biodiversité en tant que manifestation du principe de prévention. [Loi n° 2016-1087 du 8 août 2016 pour la reconquête de la biodiversité, de la nature et des paysages, NOR : DEVL1400720L, ELI : https://www.legifrance.gouv.fr/eli/loi/2016/8/8/DEVL1400720L/jo/texte]

Mitigation of self-phase modulation by sinusoidally time varying phase

2018

The propagation of intense ultra-short optical pulses in a Kerr medium such as an optical fibre remains a critical issue for many optical systems. This is because the self-phase modulation (SPM) of the propagating pulse usually causes a severe broadening of the pulse spectrum that is typically accompanied by an oscillatory structure. Several strategies have been proposed and successfully deployed to counteract the deleterious effects of SPM in fiber-optic systems, including spatial or temporal scaling to reduce the impact of nonlinearity. Other approaches rely on the exploitation of the peculiar properties of parabolic shaped pulses and self-similar evolution. However, none of these last te…

Second zero dispersion wavelength measurement through soliton self-frequency shift compensation in suspended core fibre

2008

International audience; A simple experimental technique to evaluate the second zero dispersion wavelength of very small core microstrutured fibres is described. Based on the effect of soliton self-frequency shift and its subsequent compensation in the vicinity of the second zero dispersion. the proposed method is applied to both standard and suspended core microstructured fibres by simply measuring the frequency stabilised soliton spectrum, avoiding any calculation and knowledge of any experimental parameters.

Does the Principle of Compensation Provide a Solid Basis for Establishing Corporate Environmental responsibility: A Case study of Madagascar’s Mining…

2019

The mining sector has been criticized for its lack of environmental responsibility, but a certain amount of progress has been evident. At the same time, a number of developing countries have opted for an environmental management framework underpinned by the principle of compensation. Even though this principle is closely aligned to corporate social responsibility, it does not appear to represent the most effective way of achieving corporate social responsibility. Based on a case study in Madagascar, we examine the application of the principle within a mining project and show that its inadequacy stems from failing to consider the population’s response to the actions taken by companies. In ou…

Capacités d'ajustement énergétique à court terme chez le nourrisson entre 10 et 15 mois : premiers résultats (prix SFN 2015)

2016

Introduction et but de l’etude L’equilibre de la balance energetique est maintenu soit par l’ajustement des depenses energetiques soit par l’ajustement des apports energetiques. L’enquete americaine « 2002 Feeding infants and toddlers » laisse penser qu’une diminution des capacites d’ajustement energetique se produirait autour de 11 mois. Ces capacites se deterioreraient sous l’effet des pratiques de nourrissage notamment au cours de la diversification alimentaire. Aucune etude n’a mesure les capacites d’ajustement energetique a court terme chez des nourrissons entre 10 et 15 mois. L’objectif principal de ce projet etait donc d’evaluer les capacites d’ajustement energetique a court terme a …

Short-term caloric compensation ability in infants below 15 months old

2020

International audience; Background and aims In infancy, a too rapid weight gain is a risk factor associated with overweight. Growth is linked to the infant's ability to adjust energy intake depending on the energy density of foods. Evidence regarding the behavioral aspects of appetite control ability in infancy is sparse. The objective was to study the short-term energy adjustment ability of, first, exclusively milk fed infants before the onset of complementary feeding (CF) and, second, of infants at 11 mo and 15 mo. Methods Caloric compensation ability was assessed in infants by adapting a preload paradigm. Before CF, the ‘preload' was a feed with formula made more or less caloric by conce…
