In this paper, we will use the method that shifts the positions of the exciters among the touchable nodes and measures as much as possible for each excitation. As the equations obtained by linearizing the question are underdetermined, the fast projected-Landweber algorithm is used. The first part of the scheme uses the preconditioning matrix to accelerate the iterative process, and the second part...
The steel grounding grid buried in earth will corrode and become hidden danger to the safety of power system. It is important to examine the state of grounding. Particle swarm optimization (PSO) is a population-based, self-adaptive search optimization technique. This paper used combination of rotating and encouraging each location and incentives, many measurement method, established a new non-linear...
