Discovering the determinants of job change and predicting the individual job change occasion are essential approaches for understanding the professional careers of human. However, with the evolution of labor division and globalization, modern careers become more self-directed and dynamic, which makes job change occasion difficult to predict. Fortunately, the emerging online professional networks and...
Online social networks provide a promising content dissemination platform. The information diffusion in content centric online social networks has been involving more and more media types. This paper reports on a quantitative study exploring how cross media influence the content dissemination in Sina Weibo (a popular Twitter-like microblogging site in China). Implicit cross media related features...
Active sonar systems involve the transmission and reception of one or more sequences, which provide a basis for extraction of the information on targets in the region of interest. The probing sequences at the transmitter and signal processing at the receiver play crucial roles in the overall system performance. We consider herein using CAN (cyclic algorithm-new) to synthesize probing sequences with...
In the new generation of mobile communication systems, high data transmission rate and low bit error rate has been common requirements. However the issue of signal fading in a multi-path environment still stands as a major problem. Using antenna diversity techniques can overcome the problem. In this paper, we thoroughly study the antenna diversity performance on a mobile terminal through theoretical...
In this work, diversity performance of two PIFA antennas on a small ground plane is studied. In this case, when the second antenna is located on the left edge, better diversity gain can be obtained. Matching network can be used to reduce the correlation coefficient and consequently increase the diversity gain.
