Combining Frequency-Modulated Continuous-Wave Synthetic Aperture Radar (FMCW SAR) and Displaced Phase Center Multi-beam in Azimuth (DPC-MAB) technology together can realize high-resolution wide-swath SAR imaging and take the advantages of FMCW SAR in the same time. However, when the platform velocity deviates from the theoretical speed, the azimuth signal will be periodic non-uniformly sampled which...
Dynamical behavior of a high-dimension nonlinear SEIQR model with infection-age-dependence is studied. The existence and uniqueness of positive solution of differential-integral equations is proved. By analyzing the asymptotical behaviors of the model, the threshold is found and stabilities of disease-free and endemic equilibria are obtained.
In this paper, we study the problem of gateway selection for throughput optimization in multi-radio multi-channel wireless mesh networks. In contrast to the various methodologies in the literature, we explicitly model the delay overhead that is incurred during channel switching, and consider this delay issue in the design of our mechanisms. From our best knowledge, it is the first time to take account...
