Validity, reliability, and responsiveness of daily monitoring visual analog scales in MASK-air®
2021
International audience; Background: MASK-air® is an app that supports allergic rhinitis patients in disease control. Users register daily allergy symptoms and their impact on activities using visual analog scales (VASs). We aimed to assess the concurrent validity, reliability, and responsiveness of these daily VASs. Methods: Daily monitoring VAS data were assessed in MASK-air® users with allergic rhinitis. Concurrent validity was assessed by correlating daily VAS values with those of the EuroQol-5 Dimensions (EQ-5D) VAS, the Control of Allergic Rhinitis and Asthma Test (CARAT) score, and the Work Productivity and Activity Impairment Allergic Specific (WPAI-AS) Questionnaire (work and activi…
Définir la fiabilité de l'opérateur humain pour concevoir les futurs systèmes autonomes : un regard des Facteurs Organisationnels et Humains
2022
L'intégration de systèmes autonomes dans les transports continuent de progresser afin d'atteindre, à terme, des systèmes entièrement autonomes. Le domaine du transport ferroviaire ne fait pas exception et de nombreux projets, nationaux ou internationaux, sont en cours ou voient le jour. Le transport ferroviaire est réputé sûr. Cela passe notamment par des processus de certification des systèmes ferroviaires déployés. Un principe fondamental de l'assurance de sécurité ferroviaire est : l'intégration d'une nouvelle fonction ou la modification d'une fonction ne doit pas péjorer le niveau de sécurité. Pour vérifier ce principe, le projet TA-SV a fait le choix de réaliser une comparaison par rap…
A study on The Factors Affecting Merger and Acquisition Decision In Nepalese Banking Sector
2016
Master's thesis Business Administration BE501 - University of Agder 2016 The main purpose of this study is to find out the factors that would lead to making decision regarding going for merger and acquisition among the banks in Nepalese banking sector. This thesis finds out various factors that would affect merger and acquisition decision in banking sector based upon previous studies, and tries to check whether these are significant in case of Nepalese banking sector or not. Four theories: neo-classical, agency, behavioral and resource dependency; have been taken into consideration for purpose of finding out factors affecting decision to go for merger and acquisition. Based upon the previou…
Alternaria Mycotoxins in Food and Feed: An Overview
2017
Alternariais one of the major mycotoxigenic fungal genera with more than 70 reported metabolites.Alternariamycotoxins showed notably toxicity, such as mutagenicity, carcinogenicity, induction of DNA strand break, sphingolipid metabolism disruption, or inhibition of enzymes activity and photophosphorylation. This review reports on the toxicity, stability, metabolism, current analytical methods, and prevalence ofAlternariamycotoxins in food and feed through the most recent published research. Half of the publications were focused on fruits, vegetables, and derived products—mainly tomato and apples—while cereals and cereal by-products represented 38%. The most studied compounds were alternario…
Test-Retest Reliability of Task Performance for Golf Swings of Medium- to High-Handicap Players
2022
Background: Golf swing performance in medium- to high-handicap players must be reliably measured to use this variable in both research studies and in applied settings. Nevertheless, there are no studies published on this topic and test–retest evidence is only available for low-handicap players. The aim of this study was to determine the number of attempts necessary to obtain a reliable measurement protocol for swing performance variables in medium- to high-handicap players. Methods: Ten amateur players (55.67 (13.64) years, 78.4 (11.4) kg, 1.75 (7.95) m) took part in a test–retest study in two experimental sessions one week apart. In each one, fifteen swings with a six iron and a driver wer…
The spanish body image state scale: factor structure, reliability and validity in a colombian population
2019
ObjectiveBody image is a construct highly dependent on culture and ethnicity. Furthermore, recent studies reveal that body image is not only a trait, but also a momentary state subject to change in diverse situational contexts. However, cultural influences on momentary body image have not been sufficiently investigated. To assess the influence of Latin American culture on momentary body image and to enable its comparison to Western countries, the Spanish translation of an existing state body image scale such as the Body Image States Scale (BISS) is needed. In addition, the factor structure, reliability and general validity of the Spanish BISS (S-BISS) should be evaluated prior to its applic…
Novel voltage-controlled conditioning circuit applied to the ISFETs temporary drift and thermal dependency
2003
This paper describes a novel conditioning circuit applied to ion-sensitive field-effect transistors/membrane-ion-sensitive field-effect transistors (ISFETs/MEMFETs) sensors. The novel conditioning circuit allows the sensor polarization with the needed either voltage or current required in each application, thanks to two completely independent voltage-controlled blocks (current and voltage blocks). The control of the voltage block is the most critical point in our design because the voltage block maintains the sensor feedback stable, avoiding the thermal and temporary drifts of the sensor feedback.
Maximizing energy transfer and RES integration using dynamic thermal rating
2019
Abstract The production of electricity from wind and other renewable sources is rapidly increasing all over the world, causing significant changes in the management of electrical systems. The current structural asset is not adequate to manage this growing generation of energy. The hypothesis of construction of new power lines would mean taking into consideration economic, political and social problems. The following paper reports the experience gained by the Italian TSO, Terna S.p.A, on the use of the DTR (Dynamic Thermal Rating), which is able to dynamically calculate the real transport capacity of an overhead power line. The results obtained are encouraging as they show how it is possible…
Masonry structures subjected to tsunami loads: Modeling issues and application to a case study
2020
Abstract Tsunamis are among the most dangerous natural disasters for coastal areas experiencing tsunami hazard. One of the major concerns in the assessment of strategies for the risk mitigation is to estimate vulnerability of structures and infrastructures. However, reliable approaches for the evaluation of the structural capacity under tsunami loads are nowadays not always available for all the types of structures, especially masonry. On this aim, the paper deals with the modeling issues of 3D masonry structures subjected to tsunami loads and the effect on the structural behavior of different modeling approaches. First, a brief state of the art on the available studies is presented regardi…
A Pattern Recognition Approach for Peak Prediction of Electrical Consumption
2014
Predicting and mitigating demand peaks in electrical networks has become a prevalent research topic. Demand peaks pose a particular challenge to energy companies because these are difficult to foresee and require the net to support abnormally high consumption levels. In smart energy grids, time-differentiated pricing policies that increase the energy cost for the consumers during peak periods, and load balancing are examples of simple techniques for peak regulation. In this paper, we tackle the task of predicting power peaks prior to their actual occurrence in the context of a pilot Norwegian smart grid network.
