Nouvelles technologies et aide à la compréhension de documents techniques : Construction et expérimentation d'un simulateur de fonctionnement de grue…
2001
Reading skills are more and more required to succeed professional examination. French crane drivers are concerned with this problem. In order to help them, we have conducted a study with three main steps. First, we carried out a cognitive work analysis. Second, we test several analogical modalities of written presentations focusing on the construction of a specific simulator. Finally, two experiments are presented showing a significative effect of this simulator on the comprehension of cranes technical documentation.
Adoption and Adoption Interests of Self-Tracking Technologies : Single and Multiple Technology Perspectives
2016
During the past few decades, different forms of technology based self-tracking have become increasingly common but received little attention in academic research. In this study, we aim to address this gap by examining the adoption and adoption interests of four different self-tracking technologies: exercise, activity, sleep, and nutrition tracking. The examination is conducted from both single and multiple technology perspectives and by concentrating particularly on the potential gender and age dependencies in the adoption rates and adoption patterns of the technologies. By analysing the responses collected from 824 consumers through an online survey, the results of the study are able to re…
P-on-N and N-on-P silicon photomultipliers: responsivity comparison in the continuous wave regime
2013
We report the electrical and optical comparison, in continuous wave regime, of two novel classes of silicon photomultipliers (SiPMs) fabricated on silicon P-type and N-type substrate respectively. Responsivity measurements have been performed with an incident optical power from tenths of picowatts to hundreds of nanowatts and on a broad spectrum, ranging from ultraviolet to near infrared (340-820 nm). For both classes of investigated SiPMs, responsivity shows flat response versus the optical incident power, when a preset overvoltage and wavelength is applied . More in detail, this linear behavior extends up to about 10 nW for lower overvoltages, while a shrink is observed when the reverse b…
Generación de un modelo de análisis jurídico: una aproximación sistémica a la legislación política del periodo gracano
2017
1. Introducción y metodología Con la presente investigación pretendemos aumentar el espectro de metodologías empleables para el estudio de los objetos jurídicos. Esto es, buscamos un mejor y más potente caudal metodológico para el análisis de las ciencias jurídicas y más concretamente del Derecho Romano. En el siglo pasado se vivió en el paradigma científico una auténtica revolución atómica y subatómica, y con esta revolución se prendió la llama del estudio de los sistemas: desde los sistemas fractales (como el helecho bajo el esquema de la curva de Koch) a los estudios económico-sociales (teoría de juegos, por ejemplo). La teoría general de sistemas evidencia y saca a la luz procesos que p…
"I felt like a lonely person in the desert" : a case study on factors moderating interunit communication in multinational headquarters-subsidiary rel…
2017
One of the biggest challenges for internationalizing businesses is to develop and maintain efficient internal communication processes across national and cultural borders. This thesis aims to examine what are the most important organizational structures and communicational practices for a successful multinational headquarters-subsidiary relationship, and what do the communicational practices, such as the mechanics of language use and interunit knowledge-transfer, imply about the efficiency of global co-operation. This study considers the experiences of one case company’s Finnish headquarters and Dutch subsidiary on internal communication in a crucial phase of internationalization. The data …
H1-antihistamines suppress wheal-and-flare reaction and skin blood perfusion measured by Laser Dopppler flowmetry: randomized, double-blind, placebo-…
2010
H1-antihistamines suppress wheal-and-flare reaction and skin blood perfusion measured by Laser Dopppler flowmetry: randomized, double-blind, placebo-controlled, crossover design study The aim of our study was to compare the influence of pre-treatment with H1-antihistamines (levocetirizine, desloratadine, clemastine, quifenadine, and sequifenadine) and a placebo on the histamine-induced weal and flare reaction, increase of skin blood perfusion and sedation. Thirty healthy volunteers were enrolled in the study. The study design was a prospective, randomised, double-blind, placebo-controlled, crossover, balanced clinical trial. Volunteers in randomised and double-blind order were treated with …
Disentangling directional and fluctuating asymmetry in a genome-wide association study.
2018
8 pages; International audience; Although directional and fluctuating asymmetry have been frequently assessed independently, they are indeed associated concepts both in theory and in practice. However, they can be difficult to disentangle in genome-wide association studies, where the appropriate shape statistics are not fully developed. Although the usage of Procrustes distances to overcome this problem may be tempting, this does not reliably help to identify the underlying genetic components of directional and fluctuating asymmetries. Here, similarities and differences among different approaches have revealed that the genetic component of the skull asymmetry in this population of mice is m…
Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games
2016
Small-sided and conditioned games (SSCGs) in sport have been modelled as complex adaptive systems. Research has shown that the relative space per player (RSP) formulated in SSCGs can impact on emergent tactical behaviours. In this study we adopted a systems orientation to analyse how different RSP values, obtained through manipulations of player numbers, influenced four measures of interpersonal coordination observed during performance in SSCGs. For this purpose we calculated positional data (GPS 15 Hz) from ten U-15 football players performing in three SSCGs varying in player numbers (3v3, 4v4 and 5v5). Key measures of SSCG system behaviours included values of (1) players’ dispersion, (2) …
Variable kinematics models for multilòayered smart plates
2015
Families of layer-wise and equivalent single layer advanced finite elements for the geometrically nonlinear analysis of smart multilayered plates are formulated in a unified framework. The proposed modeling strategy reduces the multifield problems to an effective mechanical plate by the condensation of the electromechanical state into the plate kinematics, which is assumed as a variable order expansion along the plate thickness. Numerical results are presented to validate the proposed modeling approach and finite elements and to investigate their features.
Multispectral filter arrays: Recent advances and practical implementation
2014
Thanks to some technical progress in interferencefilter design based on different technologies, we can finally successfully implement the concept of multispectral filter array-based sensors. This article provides the relevant state-of-the-art for multispectral imaging systems and presents the characteristics of the elements of our multispectral sensor as a case study. The spectral characteristics are based on two different spatial arrangements that distribute eight different bandpass filters in the visible and near-infrared area of the spectrum. We demonstrate that the system is viable and evaluate its performance through sensor spectral simulation. Multispectral filter arrays: Recent advan…
