Seismic activities can be seen as the composition of background and clustering earthquakes.It is important to identify seismicity clusters from background events.Based on the Nearest Neighbour Distance algorithm proposed by Zaliapin, we use the Gaussian mixture model (GMM) to fit its spatiotemporal distribution and use the probability corresponding
When approaching and removing a disabled satellite, the accuracy of the controller is imperative to the success of the mission because if the Supplements mission fails, more space debris can be produced due to satellite collision.To address this issue, a controller directly driven by discrete sample data points is proposed in this paper.First, the
With the development of urbanization, the building structures are more and more complex, and various moving objects, such as human beings, robots and unmanned aerial vehicles, often travel through indoor and outdoor 3D big girls woven tee space, which puts forward higher requirements for the accurate search and location in indoor and outdoor space.
Mobile Global Navigation Satellite System (GNSS) measurements carried out on the railway consist of using satellite Western Saddle Pad navigation systems to determine the track geometry of a moving railway vehicle on a given route.Their purposes include diagnostics, stocktaking, and design work in railways.The greatest advantage of this method is t
