Filtering Methods for Coupled Inverse Problems
SIAM Journal on Applied Dynamical Systems, 2023 We are interested in ensemble methods to solve multi-objective optimization problems. An ensemble Kalman method is proposed to solve a formulation of the nonlinear problem using a weighted function approach. An analysis of the mean field limit of the ensemble method yields an explicit update formula for the weights. Numerical examples show the improved

Well-Posedness Scheme for Coupled Fixed-Point Problems Using Generalized Contractions
Axioms, 2023 In this study, we present a more general class of rational-type contractions in the domain of Hilbert spaces, along with a novel coupled implicit relation.

Axisymmetric particle-element coupled method for deformation problems of geomaterial
Soils and Foundations, 2022 Although grid-based particle methods are widely used for engineering deformation problems, due to their robustness in large deformation analyses, the computational cost of these methods is quite high compared with mesh-based methods.

Three-Point Boundary Value Problems of Coupled Nonlocal Laplacian Equations
Mathematics, 2022 This paper discusses a kind of coupled nonlocal Laplacian evolution equation with Caputo time-fractional derivatives and proportional delays. Green function and mild solution are firstly established by employing the approach of eigenvalues’ expansions ...

Erectile dysfunction: a couple problem [PDF]
Journal of Family Planning and Reproductive Health Care, 2007 Background It used to be called ‘impotence’: a double-edged label, with its implication not only that the man is unable to persuade blood into his penis, but also that he’s powerless in sexual situations, in the relationship arena, and in life. The word was never just a medical description; it always held undertones of accusation – a word to be hurled ...

Adaptation in coupled problems [PDF]
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2010 PurposeThe purpose of this paper is to address the formulation, implementation, and adaptation of closely coupled multi‐physics problems withh‐ andp‐adaptive finite element methods. A general formulation is chosen allowing for coupled problems of various types.
