Performance Comparison of PCA,DWT-PCA And LWT-PCA for Face Image Retrieval
Computer Science & Engineering: An International Journal, 2012 This paper compares the performance of face image retrieval system based on discrete wavelet transforms and Lifting wavelet transforms with principal component analysis (PCA). These techniques are implemented and their performances are investigated using f rontal facial images from the ORL database.

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers
Advanced Functional Materials, EarlyView.Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).
