Compensation of Nonlinearity of Voltage and Current Instrument Transformers

2019

This paper aims at characterizing and improving the metrological performances of current and voltage instrument transformers (CTs and VTs) in harmonic measurements in the power system. A theoretical analysis is carried out to demonstrate that, due to the iron core nonlinearity, CT and VT output signal is distorted even when the input signal is a pure sine wave. Starting from this analysis, a new method for CT and VT characterization and compensation is proposed. In a first step, they are characterized in sinusoidal conditions and the harmonic phasors of the distorted output are measured; in the second step, these phasors are used to compensate the harmonic phasors measured in normal operati…

Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.

2014

Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…

: Un dialogue interculturel ?

2008

National audience; L'artisan nous intéresse ici comme un acteur des savoirs. Notre position universitaire n'est pas neutre, il existe une tension entre ces deux mondes dont le chercheur doit tenir compte : comment se présente l'artisan comme acteur des savoirs dans le regard des chercheurs ? Quel est le regard des artisans sur eux-mêmes et par contraste sur les chercheurs en sciences humaines et sociales comme acteurs des savoirs ? Nous proposons un jeu de miroir sur ces représentations sociales, avant d'examiner deux formes de médiation possibles. Ces expériences nous invitent à envisager un rapport aux savoirs repéré dans la figure hybride de "l'artisan-chercheur".

Application of the Information Bottleneck method to discover user profiles in a Web store

2018

The paper deals with the problem of discovering groups of Web users with similar behavioral patterns on an e-commerce site. We introduce a novel approach to the unsupervised classification of user sessions, based on session attributes related to the user click-stream behavior, to gain insight into characteristics of various user profiles. The approach uses the agglomerative Information Bottleneck (IB) algorithm. Based on log data for a real online store, efficiency of the approach in terms of its ability to differentiate between buying and non-buying sessions was validated, indicating some possible practical applications of the our method. Experiments performed for a number of session sampl…

Water and Energy Saving in Urban Water Systems: The ALADIN Project

2016

The ALADIN project was aimed at contributing to environmental and energy sustainability of the urban water system by means of a decision support tool able to allow an evaluation of the energy impact related to each different macro-sectors of urban water cycle highlighting the main energy flows and to assess the system energy balance and identify the possible energy-efficient solutions. Moreover the tool suggests the most efficient actions in reducing water losses. In the present paper the main features of the developed tool are presented. (C) 2016 The Authors.

Abitare i paesaggi inattesi: DOM – e la pratica del cammino

2022

Urbanized territories have expanded invading the space and modifying the dynamics defined over the centuries of slow development, often making the city indistinguishable from the non-city. In this condition, an unforeseen form of landscape takes place and determines itself, unexpectedly interposing between the planned meshes. By appropriating spaces transitorily rejected by hyper-functionalization, wild environments nomadically occupy empty sites until a new order to come. The practice of walking to cross spaces is an experience of comprehension that allows human beings a renewed way of dwelling in the world. The article assumes that the design process over wild areas continue to occur thro…
