International audience; Manual three-dimensional segmentation of medical images results in noisy data sets representing three-dimensional objects. Based on this data, we look at how to perform a smooth object reconstruction. In particular, we are int

The thoracic diaphragm is the muscle that drives the respiratory cycle of a human being. Using a system of partial differential equations (PDEs) that models linear elasticity we compute displacements and stresses in a two-dimensional cross section of

A least squares radial basis function finite difference method with improved stability properties

Autor: Alfa Heryudono, Elisabeth Larsson, Igor Tominec

Localized collocation methods based on radial basis functions (RBFs) for elliptic problems appear to be non-robust in the presence of Neumann boundary conditions. In this paper we overcome this issue by formulating the RBF-generated finite difference

The diaphragm is the main muscle that regulates the human respiration. When a patient is put under controlled mechanical ventilation, the diaphragm is exposed to forces that damage the muscle function. The long-term aim of this work is to study this

Local meshless methods for second order elliptic interface problems with sharp corners

Autor: Elisabeth Larsson, Siraj-ul-Islam, Masood Ahmad

In the present paper, we develop a local meshless procedure for solving a steady state two-dimensional interface problem having discontinuous coefficients and curved interfaces with sharp corners. The proposed local meshless methods are based on thre

International audience; The main objective of our research is to understand the functionality of a human diaphragm, the main muscle of the respiratory system. Its action affects the volume of the thorax cavity such that the lungs can inflate and defl

High-Performance Modelling and Simulation for Big Data Applications

Estimation of tail distributions and extreme quantiles is important in areas such as risk management in finance and insurance in relation to extreme or catastrophic events. The main difficulty from the statistical perspective is that the available da
