The superresonance effect for a hollow dielectric sphere is numerically simulated with the Mie theory. It shown first time that weakly dissipative mesoscale spheres an air-filled cavity exhibit high-order Fano resonance related to internal modes. Superresonance in achieved by accurate choice of radius, while monolithic sphere, it ensured outer diameter particle under study. In this case, relati...

We study the response and cross sections for the absorption of GW energy generated in a Jordan-BransDicke theory by a resonant mass detector shaped as a hollow sphere. As a source of the GW we take a binary system in the Newtonian approximation. For masses of the stars of the order of the solar mass, the emitted GW sweeps a range of frequencies which include the first resonant mode of the detec...

The reaction of GeBr with LiGe(SiMe(3))(3) yields the largest metalloid cluster compound of germanium Ge(14)[Ge(SiMe(3))(3)](5)Li(3)(THF)(6), in which 14 germanium atoms are arranged as a hollow sphere in the cluster core, showing that in the case of germanium also fullerene-like compounds might be present in the borderland between the molecular and solid states.

This report discusses the energy balance results observed during the simulation of the impact of an aluminum sphere on an aluminum plate supported by a hollow aluminum cylinder. Due to the high impact velocity, there is considerable ringing of the cylinder which causes the sum of the mechanical energies to increase. An optimal set of input parameters is identified that minimizes ringing and red...

The first purpose of this work was to develop efficient upper bound limit analysis tools for axisymmetric limit analysis (LA) problems, together with avoiding the specific singularities of this case of symmetry. The second main purpose concerns assessments and predictions about the macroscopic criterion of a porous material on the basis of the hollow sphere or spheroid model with a frictional m...
