This paper studies the energy efficiency problem with a roadside relay point (RP) deployment for road-condition information dissemination in a vehicular ad hoc network (VANET). In the RP deployment, a certain number of low-cost devices with simple relaying functionality are uniformly deployed between two neighbor RSUs on a highway, which can be used as a relay to help deliver road-condition information...
In applications, the signals used for order tracking of rotating machinery are often distorted by non-order components, such as the fixed frequencies arising from power-frequency interferences, and local structure resonances, which may render the results from the analysis meaningless or inaccurate. Independent component analysis (ICA), as a statistical method, has the ability to segregate multiple-sources...
