The Impact of the Network Topology on the Viral Prevalence: A Node-Based Approach. [PDF]
PLoS ONE, 2015 This paper addresses the impact of the structure of the viral propagation network on the viral prevalence. For that purpose, a new epidemic model of computer virus, known as the node-based SLBS model, is proposed.

An Approach of Eigenvalue Perturbation Theory [PDF]
Applied Numerical Analysis & Computational Mathematics, 2005 The eigenvalue problem of the form \((A+\varepsilon B)\phi(\varepsilon)= \lambda(\varepsilon) \phi(\varepsilon)\) is considered, where \(A, B\) are matrices, or more generally, differential operators. If \(A\) is selfadjoint and the eigenvalue \(\lambda(0)\) of \(A\) is simple, it is shown that \(\lambda(\varepsilon)\) has a power series expansion ...

Mixed methods for viscoelastodynamics and topology optimization [PDF]
Fracture and Structural Integrity, 2014 A truly-mixed approach for the analysis of viscoelastic structures and continua is presented. An additive decomposition of the stress state into a viscoelastic part and a purely elastic one is introduced along with an Hellinger-Reissner variational ...

Interactions due to Moving Heat Sources in Generalized Thermoelastic Half-Space using L-S Model
International Journal of Applied Mechanics and Engineering, 2013 A one-dimensional problem for a homogeneous, isotropic and thermoelastic half-space subjected to a moving plane of heat source on the boundary of the space, which is traction free, is considered in the context of Lord- Shulaman model (L-S model) of ...

A nonlocal eigenvalue problem and the stability of spikes for reaction-diffusion systems with fractional reaction rates [PDF]
, 2003 We consider a nonlocal eigenvalue problem which arises in the study of stability of spike solutions for reaction-diffusion systems with fractional reaction rates such as the Sel'kov model, the Gray-Scott system, the hypercycle Eigen and Schuster ...

Eigenvalues and poles of nonlinear systems: A geometric approach
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 The classical notions of eigenvalue and of pole of a linear system are revisited using a geometric approach and extended to nonlinear systems exploiting the notions of f — reducing manifold and of f-reducing distribution. The proposed definitions contribute to a deeper understanding of the model reduction problem at isolated singularities, recently ...
