Correction for External Mass-Transfer Resistance in Diffusive Sampling

Diffusive Mass Transfer in an Eccentric Annular Flow

The dispersion in an eccentric annulus region by taking blood as a Newtonian fluid with the investigation of oxygen transfer to the tissue cells in an eccentric catheterized artery is studied. The region bounded by eccentric circles in x-y plane is conformal mapping to concentric circles in   plane using a conformal mapping 1 . z c    The resulting governing equations are analytically solv...

Sampling diffusive transition paths.

The authors address the problem of sampling double-ended diffusive paths. The ensemble of paths is expressed using a symmetric version of the Onsager-Machlup formula, which only requires evaluation of the force field and which, upon direct time discretization, gives rise to a symmetric integrator that is accurate to second order. Efficiently sampling this ensemble requires avoiding the well-kno...

Direct Sampling Method for Diffusive Optical Tomography

In this work, we are concerned with the di↵usive optical tomography (DOT) problem in the case when only one or two pairs of Cauchy data is available. We propose a simple and e cient direct sampling method (DSM) to locate inhomogeneities inside a homogeneous background and solve the DOT problem in both full and limited aperture cases. This new method is easy to implement and less expensive compu...

Quality Control in Diffusive Sampling Networks

The urban centres are growing extremely quickly throughout Latin America and, as a consequence air pollution is also growing due to increasing traffic. The Clean Air Programme, financed by the Swiss Agency for Development and Cooperation (SDC), was carried out by the Swiss Foundation for Technical Cooperation (Swisscontact) was carried out in 6 Central American cities [1]. The project's goal wa...
