Mental health problems are highly prevalent and appear to be increasing in frequency and severity among the college student population. The upsurge in mobile and wearable wireless technologies capable of intense, longitudinal tracking of individuals, provide valuable opportunities to examine temporal patterns and dynamic interactions of key variables in(More)
Timeliness is the key requirement when AMR codec is realized in DSP. In this paper, the code optimization is implemented for the AMR codec when realizing on the TI<sup>&#x00AE;</sup> TMS320VC5509 DSP hardware platform. In order to improve the code efficiency, comprehensive assembly instructions are rewritten firstly after the comprehensive analysis on the(More)
This paper investigates the problem of guaranteed cost control for a class of uncertain distributed delay systems with neutral type. A sufficient condition for the solvability of this problem is obtained. A novel Lyapunov-Krasovskii functional is constructed to reduce conservatism of the criterion in form of LMIs. Some mathematical techniques are utilized(More)
—Traditional solutions handle security at the application layer, which causes huge signaling overhead and long delay if authentication is implemented for every signal to enhance the security of wireless communication systems. In this paper, a real-time and two-way authentication method is proposed, which is based on the characteristics of radio channel(More)
Most P2P applications require to elect some supernodes(SN) from the peers to improve the performance, so the supernode election has become an important issue in such systems. To our best knowledge, most applications assume that nodes with enough bandwidth and powerful computation, having a public IP address can become SNs, but this strategy may have some(More)
