With the widespread application of GNSS, delicate handling biases among different systems and frequencies is critical importance, wherein inter-frequency clock (IFCBs) observable-specific signal (OSBs) should be carefully corrected. Usually, a serial approach used to calculate these products. To accelerate computation speed reduce time delay, multicore parallel estimation strategy for IFCBs, co...

We study the inverse boundary value problem for the wave equation and recovery of the wavespeed upon taking a time-Fourier transform of the data. We design a hierarchical compressed reconstruction in a multilevel scheme for the inverse boundary value problem associated with the Helmholtz equation using the Dirichletto-Neumann map, or the single-layer potential operator, at selected frequencies ...

A new Multi-Stage Fuzzy (MSF) controller based on Multi-objective Harmony Search Algorithm (MOHSA) is proposed in this paper to solve the Load Frequency Control (LFC) problem of power systems in deregulated environment. LFC problem are caused by load perturbations, which continuously disturb the normal operation of power system. The objectives of LFC are to mini small size the transient deviati...
