Exact Nonlinear Spectral Analysis of Nonsmooth WENO-JS Solutions

open access: yesJournal of Applied Mathematics, 2023
The fifth-order accurate Weighted Essentially Nonoscillatory space discretization developed by Jiang and Shu (WENO-JS) is studied theoretically. An exact Nonlinear Spectral Method (NSM) is developed based on an innovative yet simple methodology.

A sufficient condition for metric subregularity of set-valued mappings between Asplund spaces based on an outer-coderivative-like variational tool

open access: yesHeliyon, 2023
In this study, we examine the Generalized Equations' subregularity in Asplund spaces utilizing a novel approach. We obtain sufficient conditions for a family of multifunctions to be metrically subregular which are stronger than the known sufficient ...

Primal-dual gap estimators for a posteriori error analysis of nonsmooth minimization problems [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 2019
The primal-dual gap is a natural upper bound for the energy error and, for uniformly convex minimization problems, also for the error in the energy norm.

Nonsmooth analysis on smooth manifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 2007
We study infinitesimal properties of nonsmooth (nondifferentiable) functions on smooth manifolds. The eigenvalue function of a matrix on the manifold of symmetric matrices gives a natural example of such a nonsmooth function. A subdifferential calculus for lower semicontinuous functions is developed here for studying constrained optimization problems ...

A Neurodynamic Approach to Nonsmooth Quaternion Distributed Convex Optimization With Inequality and Affine Equality Constraints

open access: yesIEEE Access, 2022
Quaternions have appeared in many practical fields, such as image processing and data mining, and so on. This paper focuses on designing an efficient quaternion-valued neurodynamic approach (QNA) based on multi-agent systems to solve nonsmooth convex ...

New Perspectives in Causal Relationships Between the Response of a Rocking Block and Intensity Measures via Ensemble Machine Learning Methodologies

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper investigates the ability of machine learning (ML) to characterise the response of rocking structures when subjected to recorded earthquakes. In particular, it uses the structural parameters of a rigid block and strong ground motion characteristics to train two random forest (RF) models.

Sensor based planning and nonsmooth analysis [PDF]

open access: yesProceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002
This paper describes some initial steps towards sensor based path planning in an unknown static environment. The method is a based on a sensor-based incremental construction of a one-dimensional retract of the free space. In this paper we introduce a retract termed the generalized Voronoi graph, and also analyze the roadmap of Canny and Lin's ...

Higher-order error bound for the difference of two functions

open access: yesJournal of Inequalities and Applications, 2018
Error bounds play an important role in the research of mathematical programming. Using some techniques of nonsmooth analysis, we establish some results on the existence of higher-order error bounds for difference functions with set constraints.

Generalized Newton's Method based on Graphical Derivatives [PDF]

open access: yes, 2010
This paper concerns developing a numerical method of the Newton type to solve systems of nonlinear equations described by nonsmooth continuous functions. We propose and justify a new generalized Newton algorithm based on graphical derivatives, which have
