High nighttime temperatures and humidity put strains on the electrical power grid, which resulted in power outages in some areas that rendered fans, water pumps, and air conditioners useless.
The numerical scheme is based on finite-difference approximations with staggered grids which results in implicit formulations for the momentum equations and a semi-explicit formulation for the continuity equation.
One major advantage of the present work over those reported in the literature is that the characteristic lines follow the FE grid pattern which results in fast convergence and reduction of the computational time.
The computational domain (mathcal{C}=[0,1] times[-1,1]) is therefore discretized by a uniform Cartesian grid, which automatically results in a quasi-uniform grid for ([0,+infty] times [-infty,+infty]) (see, for example, Figure 2).
Sampling on the other hand was performed using a static grid which may result in loss of information in the case when there are many small details on the image.
However, the wide-area deployments of the renewable energy sources and the high voltage direct current (HVDC) transmission bring a large number of inter-harmonics to the power grid, which may result in further power system security problems.
The invariable columns were removed after computing the force field grid descriptors which resulted in 3163 descriptors from 3268 descriptors, thus removing 105 invariable descriptors.
The second strategy deploys "absorb-upon-arrival" policy, which describes such scenario: when the energy in rechargeable battery cannot meet the need of the transmitter, the transmitter immediately draws energy from the power grid for sending data, which results in the least data delay time, but possibly more energy consumption from the power grid.
However, in the case of the quintic, the sextic and septic splines a higher number of grid points are required, which results in pentadiagonal or septadiagonal matrices.
