With the rapid development of modern communication technology, communication networks become increasingly complex environment. In order to monitor if the wireless signal with the same frequency is illegal, this paper proposes a method of intelligent recognition to CDMA2000 based on spectral correlation. First, the power spectrum is used for initial comparison, then, we use spectral correlation to...
With the rapid development of modern communication technology, the communication network environment becomes more and more complex. Aiming to meet the requirement of identifying the wireless signal, which is located in the same frequency band of WCDMA defining as an intelligent monitoring method based on spectral correlation has been identified effectively. Firstly, the power spectrum of the frequency...
This paper presents a piezoelectric energy harvester (PEH) which can convert fluid kinetic energy into electricity with vortex induced vibration (VIV). The PEH is composed by a piezoelectric cantilever beam and a cylinder extension. Dynamic response and energy harvesting of the PEH are studied numerically. It is found that maximum output power can be obtained with optimal resistance and the more power...
A mathematical model describing the antiretroviral therapy of Enfuvirtide on HIV-1 patients is developed. The effect of Enfuvirtide (formerly called T-20) by impulsive differential equations is modeled by two different drug elimination kinetics, the first-order elimination kinetics and the Michaelis-Menten elimination kinetics. The model is a non-autonomous system of differential equations. For a...
