A Chebyshev--Ritz Spectral Framework for Nonlinear Vibration of CNT-Reinforced Composite Beams

Maryam Jalili, Samad Noeiaghdam

This study develops a spectral Ritz formulation for the nonlinear free vibration analysis of carbon nanotube-reinforced composite (CNTRC) beams. Boundary-adapted Chebyshev basis fu…

Tightening Bounds on the Numerical Radius for Hilbert Space Operators

Maryam Jalili, Hamid Reza Moradi

Let $S$ be a bounded linear operator on a Hilbert space. We show that if $S$ is accretive (resp. dissipative the sense that $\frac{S - S ^{*}}{2 i}$ is positive) in the sense that…
