Groundwater pollution by chlorinated organic compounds is a major problem. Actually, these particularly toxic pollutants, permanently degrade soil and groundwater quality. Their dispersion (by solubilization and volatilization) from the pollution source zone can generate large contaminants plumes.Ch...

Battery is a major hardware component of wireless sensor networks. Most of them have no power supply and are generally deployed for a long time. Researches have been done on battery physical model and their adaptation for sensors. We present an implementation on a real sensor operating system and ho...

The study of Tunisian Small and Medium-size Enterprises (SMEs) difficulties to access to funds shows that these enterprises experience a “banking integration deficit” that can be explained by credit rationing theory. The reluctance of Tunisian banks to become involved in SMEs' financing is largely e...

I present several new relations between mutual information (MI) and statistical estimation error for a system that can be regarded simultaneously as a communication channel and as an estimator of an input parameter. I first derive a second-order result between MI and Fisher information (FI) that is...

Full text available for free at http://abstracts.aetransport.org/paper/index/id/3886/confid/18 International audience A report of the European Commission in 1998 identified various areas that can be explored to achieve a sustainable logistics. Among those areas, we discuss the reduction of fuel cons...

We consider a distributed source coding problem of $L$ correlated Gaussian observations $Y_i, i=1,2,...,L$. We assume that the random vector $Y^{L}={}^{\rm t} (Y_1,Y_2,$ $...,Y_L)$ is an observation of the Gaussian random vector $X^K={}^{\rm t}(X_1,X_2,...,X_K)$, having the form $Y^L=AX^K+N^L ,$ whe...

Multiuser Multi-Packet Transmission (MPT) from an Access Point (AP) equipped with multiple antennas to multiple single-antenna nodes can be achieved by exploiting the spatial dimension of the channel. In this paper we present a queueing model to analytically study such systems from the link-layer pe...

The work seeks to identify the possible presence of the so-called ‘Mohring effect’ within the mass transport system Puma Katari, implemented by the Municipal Government of La Paz in 2014. It starts by estimating a useful function, based on the discrete election theory and McFadden’s random utility t...

CANDIDE-R is a huge simultaneous macro-economic model which raises estimations difficulties. We avoid the problem of identification assuming that the great number of variables in our model makes it impossible that the necessary condition be not satisfied. We assume that our system converges to a sol...

In the context of a planned end to the milk quota system, the valorisation of milk is a key variable in the profitability of dairy farms. Cow’s milk derives its value from the various products of its processing. Signs of origin and quality are a major differentiating factor for specialities cheese-m...

The text in English, presented at the plenary conference (freely accessible at http://hal-polytechnique.archives-ouvertes.fr/hal-00711847/en/) provides more comprehensive explanations and an essential bibliography. The new “no model” command is proposed for motorway access regulation, a complex non-...

Language activity is based on the symbolic gap between states of things and their representation, in a linguistic system, through speech. This involves measuring the distance between what is thought in what is said and what it refers to, the distance between different ways of saying, and the distanc...

A large software system is often composed of many inter-related programs of different sizes. Using the public Eclipse dataset, we replicate our previous study on the distribution of program sizes. Our results confirm that the program sizes follow the lognormal distribution. We also investigate the i...

International audience This contribution is the first attempt to systematically review all empirical surveys that so far have been made available in the broad field of efficiency and productivity analysis using frontier estimation methodologies. We provide a systematic bibliometric review on the man...

‘titrebSummary’/titreb Face at fertility rates now well below replacement thresholds, several OECD governments are looking at measures that can mitigate the barriers faced by families wishing to have children. This article provides an overview of recent trends in fertility rates and their determinan...

The aim of this work is to better identify the determinants of daily urban bus mobility. In particular, it is necessary to examine the extent to which the quality of the bus transport offer determines the intensity of its use. A first step was to develop a local indicator describing the quality of a...

International audience A parameter estimation strategy for a conceptual rainfall–runoff (CRR) model applied to a storm sewer system in an urban catchment (Chassieu, Lyon, France) is proposed on the basis of event-by-event Bayesian local calibrations. The marginal distribution formed by locally-estim...

<p>We present the results of an assessment of ice surface elevation measurements from NASA's Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) along the CHINARE (CHINese Antarctic Research Expedition) route near the Amery Ice Shelf in East Antarctica. The validation campaign was designed and imp...

<p>The Earth energy imbalance (EEI) at the top of the atmosphere is responsible for the accumulation of heat in the climate system. Monitoring the EEI is therefore necessary to better understand the Earth's warming climate. Measuring the EEI is challenging as it is a globally integrated variable who...

The paper presents a solution to the problem of organization of a system for collecting and transmitting information about measurements from smart meters necessary for the state estimation of a low-voltage distribution network. The problems of providing the sufficiency of measurements for the observ...
