Many engineering metals are polycrystalline, as such the elasticity, crystalline orientation and grain distribution cardinal factors in determining physical properties of material. The can be measured using a number different techniques by subset these (electron back scatter diffraction, spatially resolved acoustic spectroscopy). These measurements routinely deployed materials development. Howe...

In this paper, a digital watermarking technique using new signal processing theory called compressive sensing have been implement and analysis for different embedding monochromic watermark images into color cover images. In order to implement of technique, first convert watermark image into its sparse domain and then convert into linear measurement vector using basis matrix and measurement matr...

AbstractAn EMI Camera LSI (EMcam) with a 12 x 4 on-chip 250μm x 50μm loop antenna matrix in 65nm CMOS is developed. EMcam achieves both the 2D electric scanning and 60μm-level spatial precision for the first time. The down-conversion architecture increases the bandwidth of EMcam and enables the measurement of EMI spectrum. Shared IF block scheme is proposed to alleviate the increasing power and...

A noisy underdetermined system of linear equations is considered in which a sparse vector (a vector with a few nonzero elements) is subject to measurement. The measurement matrix elements are drawn from a Gaussian distribution. We study the information-theoretic constraints on exact support recovery of a sparse vector from the measurement vector and matrix. We compute a tight, sufficient condit...

Zinc oxide nanoparticles have been synthesized by chemical reaction method.  Polyvinyl alcohol (PVA) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by PVA solution and nanozinc oxide. Polymer blend with ZnO nanoparticle composite film has prepared by casting technique.  The property of nano composites depends greatly on the chemistry of polymer matrices....

A technique is described for recovering entire 3-D shape of an object without performing registration among partially recovered 3-D shapes. The technique employs a single measurement matrix in the factorization method. A pair of cameras at a fixed position face with each other beyond an object on a turn table and take its images from opposite sides. Three pairs of the opposite views obtained fr...
