Minimal wave speed in a dispersal predator–prey system with delays

Boundary Value Problems, 2018
This paper is concerned with the minimal wave speed in a nonlocal dispersal predator–prey system with delays. We define a threshold. By presenting the existence and nonexistence of traveling wave solutions, we confirm that the threshold is the minimal ...

Static Security Risk Assessment for Islanded Hybrid AC/DC Microgrid

IEEE Access, 2019
Due to the lack of the support from the main grid, the islanded hybrid ac/dc microgrid will more likely cause the power flow severe fluctuation and even the microgrid to be split once a serious contingency occurs.

A System for Nonmonotonic Rules on the Web

, 2004
Defeasible reasoning is a rule-based approach for efficient reasoning with incomplete and inconsistent information. Such reasoning is, among others, useful for ontology integration, where conflicting information arises naturally; and for the modeling of business rules and policies, where rules with exceptions are often used.

Convergence of nonmonotone line search method [PDF]

, 2006
In this paper, we develop a new nonmonotone line search for general line search method and establish some global convergence theorems. The new nonmonotone line search is a novel form of the nonmonotone Armijo line search and allows one to choose a larger

Attractors for Nonautonomous Multivalued Evolution Systems Generated by Time-Dependent Subdifferentials

Abstract and Applied Analysis, 2002
In a real separable Hilbert space, we consider nonautonomous evolution equations including time-dependent subdifferentials and their nonmonotone multivalued perturbations.

Decomposition of Distributed Nonmonotonic Multi-Context Systems [PDF]

, 2010
Multi-Context Systems (MCS) are formalisms that enable the inter-linkage of single knowledge bases, called contexts, via bridge rules. Recently, a fully distributed algorithm for evaluating heterogeneous, nonmonotonic MCS was described in [7]. In this paper, we continue this line of work and present a decomposition technique for MCS which analyzes the ...

On weak solution of a hyperbolic differential inclusion with nonmonotone discontinuous nonlinear term

International Journal of Mathematics and Mathematical Sciences, 1999
In this paper, a hyperbolic differential inclusion with nonmonotone discontinuous and nonlinear term, which the generalized velocity acts as its variable, is studied and the existence and decay of its weak solution are obtained.

Fractional elliptic obstacle systems with multivalued terms and nonlocal operators

Nonlinear Analysis
In this paper, we introduce and study a fractional elliptic obstacle system, which is composed of two elliptic inclusions with fractional (pi, qi)-Laplace operators, nonlocal functions, and multivalued terms.

Nonmonotone spectral projected gradient methods on convex sets [PDF]

, 2015
Nonmonotone projected gradient techniques are considered for the minimization of differentiable functions on closed convex sets. The classical projected gradient schemes are extended to include a nonmonotone steplength strategy that is based on the ...
