STATE ESTIMATION IN POWER SYSTEMS UNDER RANDOM DATA ATTACK USING CORRELATION MATCHING, SEMIDEFINITE RELAXATION, AND TRUNCATED EIGENVALUE DECOMPOSITION

This work considers a state estimation problem in modern power systems from the perspective of smart grids.Due to the use of digital technology, smart grids often encounter malicious data that is deliberately injected to attack their grid operations.Such kind of perturbation could be targeted at any domain of a smart grid from household customers t

Regarding the high corrosion resistance of brass in sulfuric acid, its leaching process is the most important step in hydrometallurgical recovery of brass scraps.In this study, the electrochemical dissolution of brass chips in sulfuric acid has been investigated.The electrochemical cell voltage depends on various parameters.Regarding the complexity

Sensorineural hearing loss (SNHL), sometimes accompanied with tinnitus, is associated with dysfunctions within and outside the classical auditory pathway.The salience network, which is anchored in bilateral anterior insula and dorsal anterior cingulate cortex, has been implicated in sensory integration.Partial auditory deprivation could alter the c

To suppress the adverse effect of the gear windage phenomenon in the high-speed aeronautic industry, a shroud as an effective alternative strategy is usually to enclose gears to reduce the windage behaviors of high-speed gears.To deeply understand these no-load power losses, this paper proposes a new simulation Pewter Flask methodology based on the

The detection, characterization, and monitoring of SARS-CoV-2 recombinant variants constitute a challenge for public health authorities worldwide.Recombinant variants, composed of two or more SARS-CoV-2 lineages, often have unknown impacts on transmission, immune escape, and virulence in the early stages of emergence.We examined 4213 SARS-CoV-2 Bik
