Cell-average WENO with progressive order of accuracy close to discontinuities with applications to signal processing
2020
In this paper we translate to the cell-average setting the algorithm for the point-value discretization presented in S. Amat, J. Ruiz, C.-W. Shu, D. F. Y\'a\~nez, A new WENO-2r algorithm with progressive order of accuracy close to discontinuities, submitted to SIAM J. Numer. Anal.. This new strategy tries to improve the results of WENO-($2r-1$) algorithm close to the singularities, resulting in an optimal order of accuracy at these zones. The main idea is to modify the optimal weights so that they have a nonlinear expression that depends on the position of the discontinuities. In this paper we study the application of the new algorithm to signal processing using Harten's multiresolution. Se…
Consensus among preference rankings: a new weighted correlation coefficient for linear and weak orderings
2021
AbstractPreference data are a particular type of ranking data where some subjects (voters, judges,...) express their preferences over a set of alternatives (items). In most real life cases, some items receive the same preference by a judge, thus giving rise to a ranking with ties. An important issue involving rankings concerns the aggregation of the preferences into a “consensus”. The purpose of this paper is to investigate the consensus between rankings with ties, taking into account the importance of swapping elements belonging to the top (or to the bottom) of the ordering (position weights). By combining the structure of $$\tau _x$$ τ x proposed by Emond and Mason (J Multi-Criteria Decis…
A new position weight correlation coefficient for consensus ranking process without ties
2019
Preference data represent a particular type of ranking data where a group of people gives their preferences over a set of alternatives. The traditional metrics between rankings do not take into account the importance of swapping elements similar among them (element weights) or elements belonging to the top (or to the bottom) of an ordering (position weights). Following the structure of the τx proposed by Emond and Mason and the class of weighted Kemeny–Snell distances, a proper rank correlation coefficient is defined for measuring the correlation among weighted position rankings without ties. The one‐to‐one correspondence between the weighted distance and the rank correlation coefficient ho…

Consensus measures for preference rankings with ties: an approach based on position weighted Kemeny distance
2018
Preference data are a particular type of ranking data where some subjects (voters, judges, ...) give their preferences over a set of alternatives (items). It happens, in most of the real cases, that some items receive the same preference by a judge, giving raise to a ranking with ties. The purpose of our paper is to investigate on the consensus between rankings with ties taking into account the importance of swapping elements belonging to the top (or to the bottom) of the ordering (position weights). Combining the structure of the Taux proposed by Emond and Mason and the class of weighted Kemeny-Snell distances, we propose a position weighted rank correlation coefficient to compare rankings…
Das Bleigewicht aus dem Hofareal der Fürstin von Vix
2021
International audience; The Lead Weight from the Courtyard of the Lady of VixThe Mont Lassois near Vix, Dép. Côte d’Or, as well as the Heuneburg, counts as one of the best researched princelyseats in the early Celtic western Hallstatt zone. In 1953 the late Hallstatt grave of Vix was discovered. The old excavations(1930-1974) have been reactivated by the German-French research project »Celtic Princely Seats West of theRhine« (1991-1997) and the French PCR-project (Projet collectif de recherche) »Vix and its Environment« (since 2002)with the participation of the universities of Dijon, Kiel, Vienna and Zurich. During the investigation of the late Hallstattcourtyard of the Lady of Vix on the h…

Das Bleigewicht aus dem Hofareal der Fürstin von VixDer Mont Lassois bei Vix, Dép. Côte d’Or, zählt neben der Heuneburg zu den am besten erforschten Fürstensitzen imfrühkeltischen Westhallstattkreis. 1953 wurde das späthallstattzeitliche Fürstinnengrab von Vix entdeckt. Im Rahmendes deutsch-französischen Forschungsprojektes »Keltische Fürstensitze westlich des Rheins« (1991-1997) und desfranzösischen PCR-Projektes (Projet collectif de recherche) »Vix et son environnement« (seit 2002) mit Beteiligungder Universitäten Dijon, Kiel, Wien und Zürich wurden die Altgrabungen (1930-1974) wieder aufgenommen.

Temporal loudness weights are frequency specific
2021
Previous work showed that the beginning of a sound is more important for the perception of loudness than later parts. When a short silent gap of sufficient duration is inserted into a sound, this primacy effect reoccurs in the second sound part after the gap. The present study investigates whether this temporal weighting occurs independently for different frequency bands. Sounds consisting of two bandpass noises were presented in four different conditions: (1) a simultaneous gap in both bands, (2) a gap in only the lower frequency band, (3) a gap in only the higher frequency band, or (4) no gap. In all conditions, the temporal loudness weights showed a primacy effect at sound onset. For the…
Gender, Identities, and Material Culture in the Italic Peninsula: Burial Practices and Loom Weights in Perspective
2021
AbstractThis paper discusses the complex relationship between material culture and gender studies from a methodological point of view, with the aim of contributing to discussions in the field of Classical archaeology. First, we provide a few historiographical benchmarks for key epistemological developments, while evidencing the methodological difficulties inherent in the variability of our interpretations of burial practices and data. Then, in a second section, a case study focuses on simple objects of daily life. Discussing approaches inspired by gender studies, and considering the place of loom weights, we wish to tackle the presumption of textile work as an eminently female activity. The…
