The parareal algorithm seeks to extract parallelism in the time-integration direction of time-dependent differential equations. While it has been applied with success to a wide range of problems, it suffers from some stability issues when applied to non-di ...

MATHICSE Technical Report: Fast recovery and approximation of hidden Cauchy structure

We derive an algorithm of optimal complexity which determines whether a given matrix is a Cauchy matrix, and which exactly recovers the Cauchy points defining a Cauchy matrix from the matrix entries. Moreover, we study how to approximate a given matrix by ...

Capillarity in pressure infiltration: influence of percolation and wetting angle

Andreas Mortensen, William Craig Carter, Ludger Weber, Alain Léger, Gionata Schneider

Composite materials are often produced by pressure-infiltration of a liquid matrix into a preform of packed solid fibers or particles. Capillary forces that intervene in this process are quantified by measuring saturation curves, which are plots of the fra ...

The computational structure of environmental life cycle costing

Vincent Moreau

Existing computational methods for life cycle costing (LCC) are few and appeared inconsistent with the very definition of LCC. This article improves the common matrix-based approach in life cycle assessment as applied to LCC, correcting previous errors. Re ...

Purkinje Images: Conveying Different Content for Different Luminance Adaptations in a Single Image

Mahmut Sami Arpa

Providing multiple meanings in a single piece of art has always been intriguing to both artists and observers. We present Purkinje images, which have different interpretations depending on the luminance adaptation of the observer. Finding such images is an ...

Inkjet Printed Nanohydrogel Coated Carbon Nanotubes Electrodes For Matrix Independent Sensing

Hubert Girault, Andreas Stephan Lesch, Fernando Cortes Salazar, Véronique Amstutz

Polyacrylamide (PA) based hydrogels are used in several applications including polyacrylamide gel electrophoresis and sensing devices. Homogeneous and compact PA films can be prepared based on chemical or photopolymerization processes. However, the accurat ...

Assessment of solvent capsule-based healing for woven fibre-reinforced epoxies

Erica Manfredi

Structural fibre-reinforced composites based on brittle matrices such as epoxy resins may be subject to short-term subcritical matrix damage that develops with time to the point where it may compromise the integrity of the structure. Currently, components ...

Magnetic islands and singular currents at rational surfaces in three-dimensional magnetohydrodynamic equilibria

Joaquim Loizu Cisquella

Using the recently developed multiregion, relaxed MHD (MRxMHD) theory, which bridges the gap between Taylor's relaxation theory and ideal MHD, we provide a thorough analytical and numerical proof of the formation of singular currents at rational surfaces i ...
