Reduced basis approximation and error bounds for potential flows in parametrized geometries

In this paper we consider (hierarchical, Lagrange) reduced basis approximation and a posteriori error estimation for potential flows in affinely parametrized geometries. We review the essential ingredients: i) a Galerkin projection onto a low dimensional s ...

Assessing directed information as a method for inferring functional connectivity in neural ensembles

Michael Christoph Gastpar

Neurons in the brain form complicated networks through synaptic connections. Traditionally, functional connectivity between neurons has been analyzed using simple metrics such as correlation, which do not provide direction of influence. Recently, an inform ...

Affine Processes On Positive Semidefinite Matrices

Damir Filipovic

This article provides the mathematical foundation for stochastically continuous affine processes on the cone of positive semidefinite symmetric matrices. This analysis has been motivated by a large and growing use of matrix-valued affine processes in finan ...

Experimental Determination of the Capacity of Wall-to-Base Connections in Storage Tanks

Alain Nussbaumer, Gustavo Cortes, Eric Lattion

Earthquakes around the world have affected many unanchored tanks used for storage of gasoline. When these unanchored tanks are subjected to strong motion, the moment generated at the base, by the mass of liquid contained in the tank, will cause partial upl ...

Acridone-Benzimidazole Ring-Fused Ligands: A New Class of Sensitizers of Lanthanide Luminescence via Low-Energy Excitation

Frédéric Gumy

Two monotopic tridentate ligands, namely HLAB1 and HLAB2 have been synthesized which feature an acridone chromophore fused on a benzimidazolepyridine framework. They differ from each other by their connection points between a N-methylacridone and a N-methy ...

Seismic Behavior of Shell-to-Base Connections in Large Storage Tanks

Alain Nussbaumer, Gustavo Cortes

A study of non-anchored tanks found in Switzerland (Koller, 2003) revealed that the plastic rotation of the shell-to-bottom connection in four of the six tanks studied did not satisfy the 0.2 radians limit established by the Eurocode (Eurocode-8, 2005). Th ...

Reduced basis approximation and a posteriori error estimation for parametrized parabolic PDEs; Application to real-time Bayesian parameter estimation

Gianluigi Rozza

In this paper we consider reduced basis approximation and a posteriori error estimation for linear functional outputs of affinely parametrized linear and non-linear parabolic partial differential equations. The essential ingredients are Galerkin projection ...

Local landmark-based registration for fMRI group studies of nonprimary auditory cortex

Jean-Philippe Thiran, Reto Meuli, Dragana Viceic, Ruth Campos Casillas

Interindividual functional and structural brain variability is a major problem in group studies, in which very focal activations are expected. Architectonic studies have shown that the human primary auditory area, which is located with a great constancy on ...

Identification of Maximal Affine Term Structure Models

Pierre Collin Dufresne

Building on Duffie and Kan (1996), we propose a new representation of affine models in which the state vector comprises infinitesimal maturity yields and their quadratic covariations. Because these variables possess unambiguous economic interpretations, th ...

Dry rock avalanche propagation

Irene Manzella

Rock avalanches are catastrophic phenomena which are not yet exhaustively understood. They consist of rock mass movements of more than one million cubic metres, involving a great amount of energy and travelling farther than expected with a normal sliding f ...
