Preserving the positivity of the deformation gradient determinant in intergrid interpolation by combining RBFs and SVD: Application to cardiac electromechanics

The accurate, robust and efficient transfer of the deformation gradient tensor between meshes of different resolution is crucial in cardiac electromechanics simulations. This paper presents a novel method that combines rescaled localized Radial Basis Funct ...

Notes on Los Angeles

Alfredo Thiermann

Jean-Louis Cohen was a historian and curator of architecture who inspired and impacted the work of many. His unexpected passing this summer was a loss to the entire expanded field of architecture. A pioneer of transnational and transmedial histories of arc ...

Reflections on the use of natural light in buildings

Marilyne Andersen

The use of natural light in buildings can affect our physiological and psychological health and has comfort, behavioral, economic, and environmental consequences. ...

Coordinate Difference Matrices

Martin Vetterli, Gilles Baechler, Miranda Krekovic, Golnooshsadat Elhami

In many problems such as phase retrieval, molecular biology, source localization, and sensor array calibration, one can measure vector differences between pairs of points and attempt to recover the position of these points; this class of problems is called ...

A transmurally heterogeneous orthotropic activation model for ventricular contraction and its numerical validation

Alfio Quarteroni, Simone Rossi, Luca Barbarotta

Models for cardiac mechanics require an activation mechanism properly representing the stress-strain relations in the contracting myocardium. In this paper, we propose a new activation model that accounts for the transmural heterogeneities observed in myoc ...

Guest dynamics in methane hydrates and hydrogen hydrates under high pressure

Umbertoluca Ranieri

Hydrates of gas are non-stoichiometric inclusion compounds constituted of water and gas. Therein, the water molecules are hydrogen-bonded and form three-dimensional crystalline networks incorporating different kinds of polar or nonpolar guest gas molecules ...

Jetting from cavitation bubbles due to multiple shockwaves

Mohamed Farhat, Outi Supponen

We present experimental observations of microjets formed by cavitation microbubbles. An underwater electric discharge, applied beneath a flat free surface, produces a primary compression wave, which undergoes several phase inversions upon reflections from ...

Shear Resistance and Failure Modes of Edgewise Multiple Tab-and-Slot Joint (MTSJ) Connection with Dovetail Design for Thin LVL spruce plywood Kerto-Q Panels

Yves Weinand, Stéphane Nicolas Roche, Mira Dedijer

The objective of this study is to experimentally analyse effects of geometry variations of Multiple Tab and Slot Joint (MTSJ) connection with dovetail design on shear mechanical behaviour. Direct shear test was performed on angular (phi=90°) MTSJ connectio ...

Vestibular Processing and its Cortical Signature in Humans

Steven Gale

The vestibular system encodes rotations and translations of the head in space. While much is known about cortical processing of the classical Aristotelian sensory modalities, such as vision and touch, knowledge of how vestibular stimulation is encoded in t ...

Accurate angle estimation in smart knee prostheses via magnetic implantable and skin-mounted sensors

Kamiar Aminian, Arash Arami, Arnaud Barré

In this work we investigated how to measure concurrently flexion-extension and internal-external rotations in a smart knee prosthesis. A configuration of magnetic sensors and magnets were designed and embedded in knee prostheses in which each sensor measur ...
