A 3-D zero-thickness shell model was developed to simulate the non-spherical response of therapeutic encapsulated microbubbles subjected to ultrasound excitation. The 3-D model was compared with previous developed models for validation. This model was then utilized to study the bubble break-up during non-spherical deformations resulting from the presence of a nearby solid wall. The effect of sh...

In this work, we present a novel method to reveal azimuthal whispering gallery modes (WGMs) in a spherical microcavity coated with a nano-meter thick polyelectrolyte shell and one monolayer of CdTe semiconductor quantum dots. The new approach in this experiment is based on the deformation of the spherical shape in a non-contact way using the radiation pressure from a laser beam, which causes th...

The paper illustrates the application of a combined adaptive particle swarm optimization (A-PSO) algorithm and the finite strip method (FSM) to the lay-up optimization of symmetrically fiber-metal laminated (FML) composite shallow shell panels for maximizing the fundamental frequency. To improve the speed of the optimization process, adaptive inertia weight was used in the particle swarm optimiz...

Abstract Exact flows of an incompressible fluid satisfying the Beltrami equation inside a spherical shell are constructed in Cartesian coordinates terms elementary functions. Two scale-invariant equations defining two infinite series eigenvalues λ n and λ <m:m...
