On a BMAP / G /1 Retrial System with Two Types of Search of Customers from the Orbit60K25, 90B22A single server retrial queueing model, in which customers arrive according to a batch Markovian arrival process (BMAP), is considered. An arriving batch, finding server busy, enters an orbit....
根据下文“To stay in the earth’s orbit, the speed of a satellite must adjust to the tiniest changes in the pull of gravity. The satellite’s speed works against earth’s gravity just enough so that it doesn’t go speeding into space or falling back to the earth.(为了保持在地球轨道上...
We show that two types of spin-orbit coupling in the 2 dimensional hole gas, with and without inversion symmetry breaking, contribute to the intrinsic spin-Hall effect. Furthermore, the vertex correction due to impurity scattering vanishes in both cases, in sharp contrast to the case of usual...

Rockets carry satellites to different types and heights of orbits, based on the tasks they need to perform. Satellites closer to the earth are in low-earth orbit, which can be 200-500 miles high. The closer to the earth, the stronger the gravity is. Therefore, these satellites must travel...

Electrons and chorus waves exchange energy primarily via two types of resonant interactions: cyclotron resonance, which occurs when the Doppler-shifted wave frequency in the particle’s moving frame matches its gyro-frequency,\(\omega - k_\parallel v_c = \omega _{ce}\), and Landau resonance,...
To improve the precision of satellite tracking is an importantproblem,and people hope to research and resolve it for a long time.Thispaper,based on the developing of tracking system,presents a way whichcan be used for precise tracking and orbit determination of a satellite.supports all the CNKI...
