Target detection by means of space-based passive radar sensors generally requires the adoption of long integration time strategies to reinforce sufficiently the signal strength.These are usually based on the recovery of the target Doppler-rate to cope with the range and Doppler migration experienced over the long dwell considered.In this work, we p
To address this problem, one has CONSOLE TABLES to look at (i) societal changes and future developments, (ii) changes in health care as such and (iii) the linkage between these two.In this respect we must realize that we are living in an era where economic, technological, demographic, social and political changes are accelerating.The interface betw
Automatic text classification is a research focus and core technology in information retrieval and natural language processing.Different from the traditional text classification methods (SVM, Bayesian, KNN), the class-center vector method is an important text classification method, which has the advantages of less calculation and high efficiency.Ho
