Law enforcement in NYC and DC coordinate with federal partners to enhance security at sensitive locations following Iranian airstrikes, implementing patrols and cyber monitoring ...

The unconditionally stable associated Hermite (AH) finite-difference time domain (FDTD) with Mur's absorbing boundary condition is extended into the cylindrical coordinates system. With AH expansion ...

This paper presents a three dimensional finite-difference time-domain (FDTD) scheme in cylindrical coordinates with an improved algorithm for accommodating the numerical singularity associated with ...

Abstract In this paper, a model of the heterogeneous anelastic seismic wave problem is proposed in three-dimensional (3D) cylindrical coordinates. We use the velocity-stress formula to describe the ...

The experimental results obtained with the conventional spouted bed (Dc= 0.21 m and Dc/Di=6) were compared with the simulations. In the sequence of this works, simulations conditions (E3, E4 and E5) ...
