4998   Facile Synthesis of 2,6-Disubstituted Benzobisthiazoles: Functional Monomers for the Design of Organic Semiconductors Facile Synthesis of 2,6-Disubstituted Benzobisthiazoles: Functional Monomers for the Design of Organic Semiconductors
Jared F. Mike, Jeremy J. Inteman, Arkady Ellern and Malika Jeffries-EL    2009
The synthesis of several synthetically useful 2,6-disubstituted benzobisthiazoles is described. The method is based on the Lewis acid-catalyzed ring-closing reaction between substituted orthoesters and diamino benzene dithiol. The resulting benzobisthiazoles are obtained cleanly and in good yields. These materials are of interest for the development of new organic semiconductors.

5003   Personal authentication using palmprint with phase congruency feature extraction method Personal authentication using palmprint with phase congruency feature extraction method
   2011
Palmprint recognition is a biometric method to automatically identify a person's identity. In this paper, phase congruency method is proposed to extract features from a palm-print image for authentication. The phase congruency is one of the promising methods to analyse the image as it is invariant to image contrast and therefore can extract reliable features under varying illumination conditions. In this paper, the phase congruency features in 6 different orientations are arranged in such a mann...

5006   A fast and accurate face authentication method using hamming-trace transform. combination A fast and accurate face authentication method using hamming-trace transform. combination
   2010
Face authentication, also called face verification, is used to confirm the identity of a person by classifying the person as either the person he or she claims to be or not. For face authentication, the user generally provides a user name (and in some cases a password as well) to an authentication system that allows access to an area or system. Stored models associated with the provided username are used to verify the person′s identity and then allow or deny access. This paper proposes a f...

5009   Similarity laws for production of GeV ions from high-intensity laser-target interactions Similarity laws for production of GeV ions from high-intensity laser-target interactions
   2009
The formation of energetic (MeV-GeV) ions from the interaction of an intense ultrashort pulse laser with a "thin" (∼1 μm) lithium planar target is investigated theoretically with a two-dimensional relativistic electromagnetic particle-in-cell model. Extensive simulations for various combinations of peak laser intensities, pulse durations, and laser spot sizes indicate that just one parameter, the laser fluence (incident laser energy per unit area), is sufficient to describe the interactio...
