Organization of silicon nanocrystals by localized electrochemical etching
(2009)
Abstract : An approach to form a monolayer of organized silicon nanocrystals on a monocrystalline Si wafer is reported. Ordered arrays of nanoholes in a silicon nitride layer were obtained by combining electron beam ...
Experimental study of dynamic bending stiffness of ACSR overhead conductors
(2015)
Abstract : Aeolian vibrations of transmission line conductors may cause fretting fatigue failure at or near the location of clamped devices. At these locations, the bending stiffness variation of the conductor has a large ...
Modeling multilayered wire strands, a strategy based on 3D finite element beam-to-beam contacts - Part II: Application to wind-induced vibration and fatigue analysis of overhead conductors
(2017)
Abstract: Wind-induced loads cause electrical transmission line fatigue. Evaluation procedures consider descriptors such as deflection amplitude (Yb) and far-field vibration (fymax), which cannot relate endurance limits ...
Fabrication of x-ray masks using evaporated electron sensitive layers for back patterning of membranes
(2002)
Abstract : A process aimed at fabricating proximity x-ray lithography masks is presented. In this technique, the Ta absorber layer is deposited and patterned on the back side of the membrane and nonspin-coated electron ...
Effect of geometric parameters on the behavior of bolted GFRP pultruded plates
(2016)
Abstract : This paper presents the effect of geometric parameters on the behavior of bolted GFRP pultruded plates for civil engineering applications. After a literature review, results of an experimental analysis investigating ...
Strengthening of the net section of steel elements under tensile loads with bonded CFRP strips
(2014)
Abstract : The use of CFRP is increasingly common as a solution for the strengthening of structures, but the majority of research and applications have focused on the retrofit of concrete structures. The application of ...
Experimental investigation of multi-material aluminum-to-steel and GFRP-to-steel bonded and bolted/bonded connections
(2016)
Abstract : Through an experimental study, this paper describes the behavior of single-lap bonded, bolted and bolted/bonded connections for configurations with minimum geometric parameters proposed in design references. Two ...
Direct-write electron beam lithography in silicon dioxide at low energy
(2010)
Abstract : Electron beam lithography in silicon dioxide has been investigated with energies ranging from 0.5 up to 6 keV. The etch ratio of SiO2SiO2 has been studied and interpreted with regard to the limited penetration ...
Summation of connectivity strengths in the visual cortex reveals stability of neuronal microcircuits after plasticity
(2015)
Abstract : Background: Within sensory systems, neurons are continuously affected by environmental stimulation. Recently, we showed that, on cell-pair basis, visual adaptation modulates the connectivity strength between ...
Objets sonores : une représentation bio-inspirée, hiérarchique, parcimonieuse à très grandes dimensions utilisable en reconnaissance
(2013)
L’accent est placé dans cet article sur la structure hiérarchique, l’aspect parcimonieux de la représentation
de l’information sonore, la très grande dimension des caractéristiques ainsi que sur l’indépendance des ...
