Accurate Chebyshev collocation solutions for the biharmonic eigenproblem on a rectangle5 years agoAbstractWe are concerned with accurate Chebyshev collocation (ChC) solutions to fourth order eigenvalue problems. We consider the 1D case as…
Breast cancer diagnosis by surface-enhanced Raman scattering (SERS) of urine5 years agoAbstractBackground: There is an ongoing research for breast cancer diagnostic tools that are cheaper, more accurate and more convenient than…
Invariant sets and attractors for Hanusse-type chemical systems with diffusions5 years agoAbstractWe are concerned with Hanusse-type chemical models with diffusions. We show that some bounded invariant sets ⊂R^{N} found for the…
An extension of the second order dynamical system that models Nesterov’s convex gradient method5 years agoAbstract In this paper we deal with a general second order continuous dynamical system associated to a convex minimization problem…
