Switching losses in power devices: From dynamic on resistance to output capacitance hysteresis

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Hongkeng Zhu, Armin Jafari, Palliyage Srilak Nirmana Perera

In this paper, we review some of the main methods to characterize on-state and off-state losses in wide-band-gap devices under switching conditions. In the off-state, we will discuss about losses related to charging and discharging the output capacitance i ...

Resistances to change in urban travel behaviors

Marc-Edouard Baptiste Grégoire Schultheiss

The social discourse surrounding the climate emergency progressively infuses the society, transforming into both micro- and macro-social injunctions to change. Yet, society - grounded in a territorial, social, and cultural contingency - appears to resist t ...

DEA Self-discharge Characterization for Low Duty Cycle Applications

Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Raphaël Johannes Charles Mottet

This publication presents the characterization of self discharging Dielectric Elastomer Actuators (DEAs) in order to give place to low duty cycle applications, during which a DEA must remain actuated for long periods of time. DEAs typically present a low c ...

Optimization of multi-directional fiber architecture for resistance and ductility of bolted FRP profile joints

Thomas Keller, Lulu Liu, Xin Wang

In view of the low structural efficiency of bolted joints in pultruded fiber-reinforced polymer (FRP) profiles with mainly unidirectional (UD) fiber architecture, off-axis plies were considered as an effective way to improve bolted joint performance. An ex ...

"Impossibile da calcolare!" Il cantiere della buvette di Évian-les-Bains, fra intuizione creativa e rigore intellettuale (M.Novarina, J.Prouvé, S.Ketoff, 1955-57)

Giulia Marino

Precision mechanics: the buvette (pump room) of Évian-les-Bains is not just an architecture of great formal elegance, but above all an extraordinary technological object, a machine carefully calibrated, in equilibrium. Architectural criticism has largely d ...

On the Soil-Structure Interaction of Surface Strip Footings at Ultimate Limit State

Lyesse Laloui, Cristiano Garbellini

Theoretical methods for estimating the bearing capacity of surface strip footings usually do not consider soil-structure interaction. A few publications deal with the subject, but all of these either do not apply rigorous methods or do not consider the gen ...

Twin-box ITER joints under electromagnetic transient loads

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Stephen Alfred March

The ITER Toroidal Field (TF) coil winding packs are designed to be wound in double-pancakes. The twin-box joint provides the electrical pancake-to-pancake connection between the two Nb3Sn 68 kA conductors and electrical coil-to-bus bar connection between t ...

Analytical modelling of R-UHPFRC - RC composite members subjected to combined bending and shear

Eugen Brühwiler, Maléna Bastien Masse, Tohru Makita

The addition of a thin overlay of reinforced UHPFRC (R-UHPFRC) to a reinforced concrete (RC) element creates a composite member which can be used for the strengthening of an existing structure and in the design of new structures. With its strain hardening ...

Spatially varied flow impact on resistance in corrugated pipes

Fereshteh Bagherimiyab Hunkeler

The roughness coefficient is a significant factor in hydraulic design process, but carries vast uncertainty in practice. This paper reports the resistance coefficients of corrugated PVC pipes under different flow regimes (i.e. pressurised, gradually varied ...

Fire protection systems for building floors made of pultruded GFRP profiles. Part 1: Experimental investigations

Thomas Keller, Yu Bai

This paper presents results of experimental investigations on the behaviour of GFRP pultruded profiles exposed to fire, in order to study the viability of their structural use in floors of buildings, taking into account the fulfilment of fire resistance re ...
