Wireless Sensor Network Operating System Design Rules Based on Real-World Deployment Survey
2013
Wireless sensor networks (WSNs) have been a widely researched field since the beginning of the 21st century. The field is already maturing, and TinyOS has established itself as the de facto standard WSN Operating System (OS). However, the WSN researcher community is still active in building more flexible, efficient and user-friendly WSN operating systems. Often, WSN OS design is based either on practical requirements of a particular research project or research group's needs or on theoretical assumptions spread in the WSN community. The goal of this paper is to propose WSN OS design rules that are based on a thorough survey of 40 WSN deployments. The survey unveils trends of WSN applic…

Somatosensory Deviance Detection ERPs and Their Relationship to Analogous Auditory ERPs and Interoceptive Accuracy
2022
Abstract. Automatic deviance detection has been widely explored in terms of mismatch responses (mismatch negativity or mismatch response) and P3a components of event-related potentials (ERPs) under a predictive coding framework; however, the somatosensory mismatch response has been investigated less often regarding the different types of changes than its auditory counterpart. It is not known whether the deviance detection responses from different modalities correlate, reflecting a general prediction error mechanism of the central nervous system. Furthermore, interoceptive functions have been associated with predictive coding theory, but whether interoceptive accuracy correlates with devian…
Balance Sheet of Screening for Diabetic Retinopathy With a Mobile Non-Mydriatic Digital Camera in Burgundy, France
2009
Purpose: To assess the economic balance-sheet of screening for diabetic retinopathy (DR) with a mobile non-mydriatic digital camera in Burgundy, France, in a public health and economic perspective.Methods: The 72 lowest medicalised areas of Burgundy were visited. Retinal images were obtained with a non-mydriatic camera. To construct an economic model, we used available data on the prevalence of diabetes in Burgundy, the efficiency of the screening, the number of screened DR, blindness probability according to DR grading, the efficiency of laser therapy, the diabetic characteristics (gender, age, income, professional status and life expectancy) and medical costs induced by our campaign.Resul…
Retidiab®: Assessment of a continuing medical education website for the improvement of diabetic retinopathy management
2009
International audience; Aim: The aim of this study was to evaluate the ability of a continuing medical education (CME) website to improve the knowledge of ophthalmologists for the management of diabetic retinopathy (DR). Methods: A World Wide Web site called RETIDIAB® was created. At their first connexion, users had to answer a first test in order to evaluate their baseline level. Then they could have free access to the entire website, any time they wanted, with no obligation of duration. The website was composed of a course and different kind of trainings which were multiple choice questionnaires (MCQ) focused on the course, interpretation of diabetics’ fundus photographs, and case reports…

Polytetrafluoroethylene Films in Rigid Polyurethane Foams' Dielectric Permittivity Measurements with a One-Side Access Capacitive Sensor.
2021
As a non-metallic composite material, widely applied in industry, rigid polyurethane (PUR) foams require knowledge of their dielectric properties. In experimental determination of PUR foams’ dielectric properties protection of one-side capacitive sensor’s active area from adverse effects caused by the PUR foams’ test objects has to be ensured. In the given study, the impact of polytetrafluoroethylene (PTFE) films, thickness 0.20 mm and 0.04 mm, in covering or simulated coating the active area of one-side access capacitive sensor’ electrodes on the experimentally determined true dielectric permittivity spectra of rigid PUR foams is estimated. Penetration depth of the low frequency excitation…
Simultaneous Noise and Impedance Fitting to Transition-Edge Sensor Data Using Differential Evolution
2020
We discuss a robust method to simultaneously fit a complex multi-body model both to the complex impedance and the noise data for transition-edge sensors. It is based on a differential evolution (DE) algorithm, providing accurate and repeatable results with only a small increase in computational cost compared to the Levenberg–Marquardt (LM) algorithm. Test fits are made using both DE and LM methods, and the results compared with previously determined best fits, with varying initial value deviations and limit ranges for the parameters. The robustness of DE is demonstrated with successful fits even when parameter limits up to a factor of 10 from the known values were used. It is shown that the…

Influencia de la percepción multisensorial en la experiencia, satisfacción y felicidad del consumidor de música en vivo. Efecto moderador de la disca…
2023
La presente tesis doctoral se centra, a lo largo de cinco capítulos, en analizar la relación de la percepción multisensorial y la experiencia del consumidor en el contexto de la música en vivo. Además, estudia el efecto de esta última en la satisfacción, la felicidad subjetiva y la intención de compra, para personas con y sin discapacidad. El primer capítulo describe, por una parte, el contexto de la música y, por otra, aborda cuestiones relativas a la discapacidad de los consumidores. En el segundo capítulo se afronta la revisión de la literatura sobre: percepción multisensorial y experiencia de consumo. El tercer capítulo presenta en primera instancia el objetivo general y los objetivos e…
