Tree mortality caused by bark beetle infestation has significant effects on the ecology and value of both natural and commercial forests. Therefore, prediction of bark beetle infestations is critical in forest management. Existing predictive models, however, rarely consider the influence of long-term stressors on forest susceptibility to bark beetle infestation. In this study we introduce pre-d...

Context-aware systems use sensors in order to analyse their environment and to adapt their behaviour. We have designed and developed Sens-ation, an open and generic service-oriented platform, which provides powerful, yet easy-to-use, tools to software developers who want to develop context-aware, sensor-based infrastructures. The service-oriented paradigm of Sens-ation enables standardised comm...

In order to investigate the rate of transferring information from the sensory organ to the brain hemisphere through the averaged magnetoencephalogram (MEG) data, we propose an estimator of the time point at which cerebral evoked potential (CEP) occurs. We regard the averaged MEG as a stationary process before the occurrence of the CEP and as a nonstationary process with a mean function, whose f...

We aim at estimating a function λ : [0,1]→ R, subject to the constraint that it is decreasing (or increasing). We provide a unified approach for studying the Lp-loss of an estimator defined as the slope of a concave (or convex) approximation of an estimator of a primitive of λ, based on n observations. Our main task is to prove that the Lp-loss is asymptotically Gaussian with explicit (though u...

There is a vast literature on robust regression estimators, the bulk of which assumes that the dependent (outcome) variable is continuous. Evidently, there are no published results on the impact of tied values in terms of the Type I error probability. A minor goal in this paper to comment generally on problems created by tied values when testing the hypothesis of a zero slope. Simulations indic...

Preevent and event landslide deformations have been detected and measured for the landslide that occurred on 3 December 2013 on the south-western slope of the Montescaglioso village (Basilicata Region, southern Italy). In this paper, ground displacements have been mapped through an integrated analysis based on a series of high resolution SAR (Synthetic Aperture Radar) images acquired by the Ita...

We consider a spatial functional linear regression, where scalar response is related to square-integrable process. use smoothing spline estimator for the slope parameter and establish finite sample bound variance of this estimator. Then we give optimal prediction error under mixing dependence. Finally, illustrate our results by simulations an application ozone pollution forecasting at nonvisite...

cet article s’intéresse aux titres littéraires et aux problèmes de leur traduction.  les stratégies de traduction sont plus nombreuses que ce que l’on croit; mais l’objectif de toute traduction est la restitution du sens. or à travers cette recherche, nous avons tenté de démontrer que la restitution du sens du titre original ne suffit absolument pas. en effet, le travail sur les mots d’un titre...
