Burr, Lomax, Pareto, and Logistic Distributions from Ultrasound Speckle [article]

Kevin J. Parker, Sedigheh S. Poul
2020 arXiv   pre-print
Examples are given from simulations and animal studies, and the theoretical fit to these preliminary data support the overall framework as a plausible model for characterizing ultrasound speckle statistics  ...  In that case an analysis of cylindrical scattering structures arranged across a power law distribution of sizes is warranted.  ...  (a) 3D orientation of the transducer and random cylindrical scatterers in the simulation domain.  ...

Meshless techniques for anisotropic diffusion

Annamaria Mazzia, Giorgio Pini, Flavio Sartoretto
2014 Applied Mathematics and Computation  
A good numerical method would be locally mass conservative, produce no or minimal over/under-shoots, produce minimal numerical diffusion, and require no CFL time-step limit for stability.  ...  The latter would allow better use of parallel computers, since time-stepping is essentially a serial process. Moreover, it would be good for the methods to be of high order accuracy.  ...  We show how to solve the equations using a global implicit approach in an efficient way, and we present the derived computational results.  ...
