Impacts on a stationary tetrahedral array of spheres
نویسندگان
چکیده
We report the peculiar behavior of the oblique impacts of a single sphere on stationary like spheres arranged in a tetrahedral array. We compare the resulting kinematic coefficient of normal restitution to that in impacts on a single sphere attached to a thick plate and in binary impacts. The results provide detailed insight into the generation of ejecta in the saltation process.

Light Trapping above the Light Cone in One-Dimensional Arrays of Dielectric Spheres
We demonstrate bound states in the radiation continuum (BSC) in a linear periodic array of dielectric spheres in air above the light cone. We classify the BSCs by orbital angular momentum m = 0,±1,±2 according to the rotational symmetry of the array, Bloch wave vector β directed along the array according to the translational symmetry, and polarization. The most simple symmetry protected BSCs ha...

This paper deals with Direction of Arrival (DOA) Estimation using Uniform linear array (ULA) for the case of more sources than sensors in the array processing. Khatri-Rao subspace approach, introduced for DOA estimation for this, in non-stationary signal model. The technique will be shown to be capable to handle stationary signals, too. Identifiability conditions of this approach are addressed....
متن کاملP-30: Developmental Capacity and Blastocyst Formation of Thawed Tetrahedral Versus Non-Tetrahedral 4-cell Stage Mouse Embryos After Vitrification
Background: It was reported in a literature that approximately one third of the 4-cell stage embryos did not exhibit a tetrahedral shape. Non-tetrahedral embryos showed a lower in vitro developmental potential than tetrahedral embryos. Recently vitrification technology has been widely employed for embryo cryopreservation. The objective of this study was to prove our hypothesis that vitrified - ...
متن کاملTetrahedral Mesh Construction for Unit Tangent Bundle over Genus-Zero Surfaces
Unit tangent bundle of a surface carries various information of tangent vector fields on that surface. For 2-spheres (i.e. genus-zero closed surfaces), the unit tangent bundle is a closed 3-manifold that has non-trivial topology and cannot be embedded in R. Therefore it cannot be constructed by existing mesh generation algorithms directly. This work aims at the first discrete construction of un...
متن کاملThe route to fullernoid oxides.
Tetrahedral oxides, like silicates and aluminates, have attracted great interest due to their potential for numerous applications in various fields ranging from catalysis, ion exchange and molecular sieves, to thermo- and photoluminescence. In spite of their tetrahedral character, no effort has been made to date for establishing structural relationships between these tetrahedral oxides with dif...
