Degenerate Diffusion Processes

, 2020
In this chapter, we show that the degenerate points may separate the state space into different regions for multiple classes, and we discuss the optimization of multi-class degenerate diffusion processes. We also show that under some conditions, the performance function of finite-horizon optimization problems, or the potential function of the long-run ...

Optimal filtering for degenerate nonlinear diffusions

Proceedings of the 38th IEEE Conference on Decision and Control (Cat. No.99CH36304), 2003
The optimal filtering problem for a nonlinear stochastic system with a non-elliptic diffusion term is studied. Under a more general geometric assumption involving the system reachability, (which includes the strong elliptic case), a Zakai-like equation is derived, and the existence and unicity of the solution is proved.

Non-local Degenerate Diffusion Coefficients Break Down the Components of Positive Solutions

Advanced Nonlinear Studies, 2019
This paper deals with nonlinear elliptic problems where the diffusion coefficient is a degenerate non-local term. We show that this degeneration implies the growth of the complexity of the structure of the set of positive solutions of the equation ...

Diffusion-weighted imaging in Wallerian degeneration

Journal of the Neurological Sciences, 2000
We report two patients displaying hyperintensities on diffusion-weighted imaging (DWI) in the area of Wallerian degeneration (WD) at 12 days after stroke. High signal intensities were more conspicuous on DWI than on T2-weighted images. Both patients showed decreased diffusion anisotropy resulting in elevated apparent diffusion coefficient in the area ...

Diffuse Aneurysmal Degeneration of the Femoropopliteal Artery

Archives of Surgery, 1970
Atherosclerotic aneurysm of the Lpopliteal artery is a well-recognized clinical entity, while aneurysm is uncommon in the femoral artery and rare in the superficial femoral artery. We have found only one report 1 of diffuse aneurysmal degeneration of the femoropopliteal artery, and for this reason the following case is being reported. Report of a Case

Boundedness of Solutions to a Degenerate Diffusion Equation

2017
The diffusion equation with a bounded saturation range under the time derivative and with Robin boundary conditions is shown to admit a regular bounded solution provided that the saturation function and the permeability coefficient have controlled decay at infinity.
