EMI Worsening in a SMPS with Non-linear Inductor

2022

This paper is focused on the input current in a Switched Mode Power Supply (SMPS) in which the power inductor is exploited up to the saturation showing a non-linear behaviour. The input current exhibits a distortion due to the non-linearity. The electromagnetic interference (EMI) caused by the ripple at switching frequency, superimposed to the DC value of the input current, requires a suitable design of the input differential mode (DM) filter. The input current is analyzed both in the time and frequency domain for different operating conditions, and it is compared to a SMPS equipped with a traditional linear inductor.

Bayesian temporal and spatio-temporal Markov switching models for the detection of influenza outbreaks

2017

Influenza is a disease which affects millions of people every year and causes hundreds of thousends of deads every year. This disease causes substantial direct and indirect costs every year. The influenza epidemic have a particular behavior which shapes the statistical methods for their detection. Seasonal epidemics happen virtually every year in the temperate parts of the globe during the cold months and extend throughout whole regions, countries and even continents. Besides the seasonal epidemics, some nonseasonal epidemics can be observed at unexpected times, usually caused by strains which jump the barrier between animals and humans, as happened with the well known Swine Flu epidemic, w…

Auditory cortical and hippocampal-system mismatch responses to duration deviants in urethane-anesthetized rats

2013

Any change in the invariant aspects of the auditory environment is of potential importance. The human brain preattentively or automatically detects such changes. The mismatch negativity (MMN) of event-related potentials (ERPs) reflects this initial stage of auditory change detection. The origin of MMN is held to be cortical. The hippocampus is associated with a later generated P3a of ERPs reflecting involuntarily attention switches towards auditory changes that are high in magnitude. The evidence for this cortico-hippocampal dichotomy is scarce, however. To shed further light on this issue, auditory cortical and hippocampal-system (CA1, dentate gyrus, subiculum) local-field potentials were …

Stability of stochastic nonlinear systems with state-dependent switching

2013

In this paper, the problem of stability on stochastic systems with state-dependent switching is investigated. To analyze properties of the switched system by means of Itô’s formula and Dynkin’s formula, it is critical to show switching instants being stopping times. When the given active-region set can be replaced by its interior, the local solution of the switched system is constructed by defining a series of stopping times as switching instants, and the criteria on global existence and stability of solution are presented by Lyapunov approach. For the case where the active-region set can not be replaced by its interior, the switched systems do not necessarily have solutions, thereby quasi-…

Réponses du d13C au forçage astronomique dans divers contextes de production carbonatée : le cas du Valanginien du Sud-Est de la France

2018

International audience; Le d13C est un outil fréquemment utilisé pour établir des échelles de temps astronomiques en milieu (hémi-) pélagique. Pourtant le lien entre d13C et forçage astronomique n’est pas toujours clair, tant les sources de carbone sont multiples. Nous avons comparé le d13C à la susceptibilité magnétique (SM) et aux cortèges argileux dans les séries marno-calcaires du Valanginien du Bassin Vocontien (SE France). Ces deux signaux sont fréquemment utilisés pour détecter un forçage astronomique dans les alternances marno-calcaires. Deux intervalles de 400 ka (correspondant à un cycle de grande excentricité) ont été ciblés, l’un avant la crise des producteurs carbonatés associé…

A Research Agenda for Evaluating Strength of Internal Preferences and External Influences in Consumer Smartphone Switching

2015

This article proposes a research agenda to study what causes consumers to switch smartphone manufacturer and operating system brands. International consumer survey is planned for data collection and structural equation modeling method will be used to extrapolate whether internal preferences play a larger role than external influences in consumers’ switching behavior. The effects are expected to be moderated by behavioral control, subjective uncertainty and prior switching experience and controlled with a set of constraint variables. As a theoretical contribution, we propose a new theory to evaluate switching primarily through the latent construct of magnitude of switch. Potential practical …

[Optimization of systemic treatments for chronic plaque psoriasis. Recommendations for switching and transitioning.]

2014

The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching.A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion.In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the…

Why Do Users Switch Mobile Applications? : Trialing Behavior as a Predecessor of Switching Behavior

2018

Mobile application providers face high user losses because users can easily and often switch to an alternative application. Researchers have recently started to study information technology (IT) switching. However, no studies have concentrated on the unique context of mobile applications. Mobile application switching differs from the switching behavior related to many other IT products and services because of the highlighted role of alternatives, beta versions, updates, reviews, and users’ spontaneous behavior. To address this gap, we develop a mobile-specific model by using a qualitative research approach. As a theoretical contribution, we introduce trialing behavior as a predecessor of sw…
