In recent years,several random key pre-distribution schemes have been proposed to bootstrap keys for encryption,but the problem of key and node revocation has r
Two probabilistic methods are extended to research multi-class motor imagery of brain-computer interface(BCI):support vector machine(SVM) with posteriori probab
We propose a two-stage method for detecting circular objects in this paper. In the first stage, curves are divided as linear segments or nonlinear segments. A least square estimator is used to find th
An operation system (OS), named TaraxOS for wireless sensor networks is proposed. The functions of the TaraxOS such as interrupt, memory management and scheduli
We theoretically present the intrinsic limits to electron mobility in the modulation-doped Al Ga N/Ga N two-dimensional electron gas(2DEG) due to effects includ
