Validity of three smartwatches in estimating energy expenditure during outdoor walking and running.

2022

Commercially wrist-worn devices often present inaccurate estimations of energy expenditure (EE), with large between-device differences. We aimed to assess the validity of the Apple Watch Series 6 (AW), Garmin FENIX 6 (GF) and Huawei Watch GT 2e (HW) in estimating EE during outdoor walking and running. Twenty young normal-weight Chinese adults concurrently wore three index devices randomly positioned at both wrists during walking at 6 km/h and running at 10 km/h for 2 km on a 400- meter track. As a criterion, EE was assessed by indirect calorimetry (COSMED K5). For walking, EE from AW and GF was significantly higher than that obtained by the K5 (p < 0.001 and 0.002, respectively), but…

Evaluation of alveolar cortical bone thickness and density for orthodontic mini-implant placement.

2013

Objective: Mini-implant stability is primarily related to bone quality and quantity. This study evaluated alveolar cortical bone thickness and density differences between interradicular sites at different levels from the alveolar crest, and assessed the differences between adolescents (12-18 years of age) and adults (19-50 years of age), males and females, upper and lower arch, anterior and posterior region of jaws and buccal and oral side. Study Design: In this retrospective study, 48 Computed Tomography scans, performed for oral surgery purposes were selected from dental records of 3,223 Caucasian orthodontic patients. The SimPlant software (Materialise, Leuven, Belgium) was used to measu…

Feasibility of conductive embroidered threads for I 2 C sensors in microcontroller-based wearable electronics

2023

Abstract In recent years, the importance of flexible and textile electronics in the field of wearable devices has continuously increased, as they are expected to replace conventional wires that exhibit limited resistance to the mechanical stress occurring in on-body applications. Wearable health devices (WHDs) can provide physiological information about various body parts and employ distributed sensor networks. Among the sensors typically integrated within WHDs, those based on the I2C communication protocol are very common and exploit signals transmitted at frequencies up to hundreds of kilohertz. Therefore, robust communication is required to guarantee a proper transmission of the signal a…

« Présentation d'un outil d'évaluation de l'évolution des processus psychiques au sein d'un dispositif thérapeutique en clinique du traumatisme »

2022

Objectives: Our project consists in the implementation and the evaluation of a care system for children in a child protection NGO in Cambodia. In view of the cultural differences and specificities of the field, taking into account only the symptoms does not seem to sufficiently account for the processes involved within the system. Based on the observation that there is a lack of tools that would allow us to apprehend these processes, our study focused on the creation of a scoring grid for psychological processes that could be used in the humanitarian field and could support clinical practice. Method: During one year, we met ten children confronted with traumatogenic events, within a device …

Overview of Power Electronic Switches: A Summary of the Past, State-of-the-Art and Illumination of the Future.

2020

As the need for green and effective utilization of energy continues to grow, the advancements in the energy and power electronics industry are constantly driven by this need, as both industries are intertwined for obvious reasons. The developments in the power electronics industry has over the years hinged on the progress of the semiconductor device industry. The semiconductor device industry could be said to be on the edge of a turn into a new era, a paradigm shift from the conventional silicon devices to the wide band gap semiconductor technologies. While a lot of work is being done in research and manufacturing sectors, it is important to look back at the past, evaluate the current progr…

Näkövammaisten apuvälineiden käytettävyys

2015

Näkövammaisille apuvälineet ovat elämää helpottavia, hyödyllisiä, pakollisia, kiusallisiakin mutta välttämättömiä. Ne tarjoavat mahdollisuuden itsenäiseen elämään, harrastamiseen ja työskentelyyn ihmisille, joille se ei ilman olisi mah-dollista. Tutkimuksessa halusin selvittää, millä tasolla näkövammaisten apuvälineiden käytettävyys on tällä hetkellä ja mitä parannettavaa siinä olisi tulevaisuudessa. Tarkoitus oli myös selvittää, mitä apuvälineitä näkövammaiset oikeasti käyttävät. Erityishuomiota tutkimuksessa saivat liikkumisen apuvälineet. Selvittääkseni näitä asioita suoritin käyttäjäkyselyn varsinaiselle käyttäjäryh-mälle. Tämä tehtiin näkövammaisten keskustelufoorumin kautta sähköisest…

Welded section defence by LRPD devices

2023

The present paper concerns a special application of some recently proposed structural devices, called LRPD, able to protect the welded sections of frame steel structures from undesired brittle collapse ensuring the good expected ductile behaviour. Standard I-shaped cross-sections are treated, and the proposed devices are suitably considered as moment resisting connections between beams and columns. At first the domain representing the brittle safe conditions is defined in the N,V,M space; then a sample plane frame subjected to seismic load conditions is studied and it is proved that, equipping the structure with the proposed devices suitably designed, the generalized stresses at the welded …

Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era

2018

The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…
