Testing the Universal Soil Loss Equation-MB equation in plots in Central and South Italy

2019

Planning soil conservation strategies requires predictive techniques at event scale because a large percentage of soil loss over a long-time period is due to relatively few large storms. Considering runoff is expected to improve soil loss predictions and allows relation of the process-oriented approach with the empirical one, furthermore, the effects of detachment and transport on soil erosion processes can be distinguished by a runoff component. In this paper, the empirical model USLE-MB (USLE-M based), including a rainfall-runoff erosivity factor in which the event rainfall erosivity index EI30 of the Universal Soil Loss Equation (USLE) multiplies the runoff coefficient QR raised to an ex…

Laudun-l'Ardoise (30), Excoutellier

2021

Le diagnostic de l’Excoutellier a permis de confirmer la présence d’un site protohistorique pointé dans les années 1990 par les prospections menées par le groupe archéologique de la vallée de La Tave et coordonnées par Hervé Petitot. Installée sur le flanc sud-ouest du plateau de Lacau, cette occupation de bas de pente se caractérise par quelques aménagements fossoyés associés à des structures de combustion. Un mobilier relativement riche (plus de 1600 fr. de céramique) permet d’envisager une mise en place de l’occupation à la toute fin de l’âge du Bronze, occupation qui dure probablement jusqu’aux premiers temps de l’âge du Fer. Malgré la mise en terrasses du secteur à la période moderne, …

Occupations protohistoriques et médiévales en marge du village actuel de Ruvigny : Ruvigny, Aube "Proche l'Eglise". Document final de synthèse

2018

L’occupation se caractérise tout d’abord par une batterie au moins une soixantaine de silos de la transition entre le premier et le second Âge du Fer avec un bruit de fond Néolithique (mobilier résiduel) et Bronze final (quelques fosses et silos). Certains de ces silos ont livré un important mobilier céramique qui, couplé à des rejets de forges et des objets attestant d’un travail de tissage, pourrait indiquer la présence d’un habitat associé à proximité immédiate. L’activité métallurgique est attestée dès le Hallstatt D3.Si aucune inhumation n’a été retrouvé dans les silos, quelques ossements humains épars ont été prélevé dans quatre d’entre eux. Il faut également noter la présence du dépô…

Évolution urbaine d'un secteur de l'agglomération antique d'Intaranum : Entrains-sur-Nohain, 16 route d'Etais : rapport de fouille

2014

Cette opération a permis de comprendre l’organisation et l’évolution d’un quartier urbain de l’agglomération d’Intaranum sur les cinq premiers siècles de notre ère.Située immédiatement à l’est d’une voie reliant Entrains à Auxerre, la parcelle fouillée semble n’être investie que vers le début du Ier s. Les premiers indices d’occupation livrent l’image d’un paysage rural, peu anthropisé, centré chronologiquement sur la période augustéenne. La zone va bénéficier très rapidement de la mise en place d’une voie est-ouest, implantée de manière non perpendiculaire à l’axe principal, et qui semble polariser l’organisation générale du quartier. De part et d’autre, elle est équipée de portiques derri…

Measuring the Task Induced Oscillatory Brain Activity Using Tensor Decomposition

2019

The characterization of dynamic electrophysiological brain activity, which form and dissolve in order to support ongoing cognitive function, is one of the most important goals in neuroscience. Here, we introduce a method with tensor decomposition for measuring the task-induced oscillations in the human brain using electroencephalography (EEG). The time frequency representation of source-reconstructed singletrail EEG data constructed a third-order tensor with three factors of time ∗ trails, frequency and source points. We then used a non-negative Canonical Polyadic decomposition (NCPD) to identify the temporal, spectral and spatial changes in electrophysiological brain activity. We validate …

SparseHC: A Memory-efficient Online Hierarchical Clustering Algorithm

2014

Computing a hierarchical clustering of objects from a pairwise distance matrix is an important algorithmic kernel in computational science. Since the storage of this matrix requires quadratic space with respect to the number of objects, the design of memory-efficient approaches is of high importance to this research area. In this paper, we address this problem by presenting a memory-efficient online hierarchical clustering algorithm called SparseHC. SparseHC scans a sorted and possibly sparse distance matrix chunk-by-chunk. Meanwhile, a dendrogram is built by merging cluster pairs as and when the distance between them is determined to be the smallest among all remaining cluster pairs. The k…

Continuum: A spatiotemporal data model to represent and qualify filiation relationships

2013

International audience; This work introduces an ontology-based spatio-temporal data model to represent entities evolving in space and time. A dynamic phenomenon generates a complex relationship network between the entities involved in the process. At the abstract level, the relationships can be identity or topological filiations. The existence of an identity filiation depends on whether the object changes its identity or not. On the other hand, topological filiations are based exclusively on the spatial component, like in the case of growth, reduction, merging or splitting. When combining identity and topological filiations, six filiation relationships are obtained, forming a second abstrac…
