Abstract This paper presents a model of cascading failures in cyber-physical power systems (CPPSs) based on an improved percolation theory, and then proposes failure mitigation strategies.In this model, the dynamic development of cascading failures is divided into several iteration stages.The power flow in the power grid, along with the data transm
In this paper, GNSS interferometric reflectometry (GNSS-IR) is firstly proposed to estimate ground surface subsidence caused by underground coal mining.Ground subsidence on the main direction of a coal seam is described by using the probability integral model (PIM) with unknown parameters.Based on the laws of reflection in geometric optics, model o
Abstract Anopheles triannulatus bachmanni biting man were collected at Aripuana, Mato Grosso.In paired catches less than 5% of the insects were collected biting inside houses, most insects were 7gm pravana collected at the edge of the rain forest at sunset.Physiological age determination indicated an even hyfrodol age distribution in the females bu
This is an account of a process, the working together of cross-disciplinary insights between an artist and a historian, to create a means by which members of the public might encounter the past on their own terms.In the summer of 2009, the historian [MB] and the conceptual artist [PB] decided to collaborate on a project click here based around even
