In this paper, we propose a novel feature extraction method called sparse local Fisher discriminant analysis (SLFDA), which is an extension of the local Fisher discriminant analysis (LFDA) algorithm. The proposed method projects the training samples into the range space of local total scatter matrix. Then, it gives the explicit characterization for all solutions of the LFDA. To obtain the sparse projection...
A piezoelectric plasma micro-thruster (PPMT) is being developed as a thruster for attitude adjustment of nano-satellites. The PPMT consists of a RF driven PZT film operating as a step-up voltage transformer, which can ionize neutrals and accelerate ions and electrons in plasma. The PPMT was driven with a low voltage through the thickness at the resonance frequency in the radial direction. To simulate...
