Maximum-principle preserving space-time isogeometric analysis [PDF]

open access: yes, 2019
In this work we propose a nonlinear stabilization technique for convection-diffusion-reaction and pure transport problems discretized with space-time isogeometric analysis. The stabilization is based on a graph-theoretic artificial diffusion operator and

Objective Bayesianism and the Maximum Entropy Principle

open access: yesEntropy, 2013
Objective Bayesian epistemology invokes three norms: the strengths of our beliefs should be probabilities; they should be calibrated to our evidence of physical probabilities; and they should otherwise equivocate sufficiently between the basic ...

Maximum Entropy Principle in Image Restoration

open access: yesAdvances in Electrical and Computer Engineering, 2018
Many imaging systems are faced with the problem of estimating a true image from a degraded dataset. In such systems, the image degradation is translated into a convolution with a Point Spread Function (PSF) and addition of noise.

A Strong Maximum Principle for Nonlinear Nonlocal Diffusion Equations

open access: yesAxioms, 2023
We consider a class of nonlinear integro-differential equations that model degenerate nonlocal diffusion. We investigate whether the strong maximum principle is valid for this nonlocal equation. For degenerate parabolic PDEs, the strong maximum principle

Maximum principle for problem of circuit optimisation

open access: yesElectronics Letters, 2016
The solution of a problem of circuit optimisation for minimum possible CPU time is obtained on the basis of the maximum principle of Pontryagin. It is shown that the effect of acceleration of the optimisation process that was studied earlier coincides ...

Stochastic maximum principle for optimal control of SPDEs [PDF]

open access: yes, 2012
In this note, we give the stochastic maximum principle for optimal control of stochastic PDEs in the general case (when the control domain need not be convex and the diffusion coefficient can contain a control variable)

A parabolic analogue of Finn's maximum principle

open access: yesAbstract and Applied Analysis, 1998
We obtain a parabolic analogue of the well-known maximum principle established by R. Finn for solutions of the minimal surface equation.

On the strong maximum principle [PDF]

open access: yesProceedings of the American Mathematical Society, 2001
This paper is concerned with the variational problem: \[ \text{minimize }\int_\Omega f(|\nabla u|) \,dx \quad\text{on }u^0+ W_0^{1,1}(\Omega), \tag{1} \] where \(u^0\) is a given function in \(W^{1,1}(\Omega)\) and \(f\) is a nonnegative, extended valued, lower semicontinuous, and convex function on \(\mathbb R\) such that \(f(0)= 0\), and where ...

Belief Reliability Distribution Based on Maximum Entropy Principle

open access: yesIEEE Access, 2018
Belief reliability is a new reliability metric based on the uncertainty theory, which aims to measure system performance incorporating the influences from design margin, aleatory uncertainty, and epistemic uncertainty.

On the strong maximum principle for nonlocal operators [PDF]

open access: yesMathematische Zeitschrift, 2017
In this paper we derive a strong maximum principle for weak supersolutions of nonlocal equations of the form $$\begin{aligned} Iu=c(x) u \qquad \text { in }\,\Omega , \end{aligned}$$Iu=c(x)uinΩ,where $$\Omega \subset \mathbb {R}^N$$Ω⊂RN is a domain, $$c ...
