This article concerns the Riesz basis property and the stability of a damped Euler-Bernoulli beam with nonuniform thickness or density. that is clamped at one end and is free at the other. To stabilize the system. we apply a linear boundary control force in position and velocity at the free end of the beam. https://www.diegojavierfares.com/flash-offer-Finney-Two-Handle-High-Arc-Bathroom-Faucet-p8561-super-offer/
