Robust estimator framework in diffusion tensor imaging [PDF]
, 2013 Diffusion of water molecules in the human brain tissue has strong similarities with diffusion in porous media. It is affected by different factors such as restrictions and compartmentalization, interaction with membrane walls, strong anisotropy imposed ...

Algorithm for Vertical Diffusion
Coastal Engineering 1976, 1976 A mathematical method and a computer algorithm is developed for the case of one-dimensional vertical mixing for an estuary with rather small advection. In the case under consideration varies the diffusion coefficients both with time and depth, and the case is therefore closer to actual estuaries than earlier computing methods that applies constant ...

Algorithms for Computing Diffuse Reflection Paths in Polygons [PDF]
The Visual Computer, 2009 Let s be a point source of light inside a polygon P of n vertices. A polygonal path from s to some point t inside P is called a diffuse reflection path if the turning points of the path lie on polygonal edges of P . We present three different algorithms for computing diffuse reflection paths from s to t inside P .

Fast Algorithms for Hyperspectral Diffuse Optical Tomography [PDF]
SIAM Journal on Scientific Computing, 2015 The image reconstruction of chromophore concentrations using Diffuse Optical Tomography (DOT) data can be described mathematically as an ill-posed inverse problem. Recent work has shown that the use of hyperspectral DOT data, as opposed to data sets comprising of a single or, at most, a dozen wavelengths, has the potential for improving the quality of ...

On Reducing the Communication Cost of the Diffusion LMS Algorithm [PDF]
IEEE Transactions on Signal and Information Processing over Networks, 2019 The rise of digital and mobile communications has recently made the world more connected and networked, resulting in an unprecedented volume of data flowing between sources, data centers, or processes. While these data may be processed in a centralized manner, it is often more suitable to consider distributed strategies such as diffusion as they are ...
