Human Protein Reference Database (HPRD) (http://www.hprd.org) was developed to serve as a comprehensive collection of protein features, post-translational modifications (PTMs) and protein-protein interactions. Since the original report, this database has increased to >20 000 proteins entries and has become the largest database for literature-derived(More)
Recent developments in fracture mechanics analyses of the interfacial crack problem are reviewed. The intent of the review is to renew the awareness of the oscillatory singularity at the crack tip of a bimaterial interface and the problems that occur when calculating mode mixity using numerical methods such as the finite element method in conjunction with(More)
Demand for new and robust techniques for digital data security and privacy are increasing with advancement of digital communication, Internet and cloud based storage. Cryptography combined with steganography is considered as a good measure of privacy protection scheme. However conventionally, steganography deals with the hiding of text or audio or image(More)
During Recent days, huge importance is given to Reversible Data Hiding(RDH) techniques in images, since it assures the excellent feature of retrieving the original cover image information in a lossless manner after embedded secret information is extracted, while protecting the image contents confidentiality. This paper proposes a lossless data hiding scheme(More)
Offline signature verification system finds several applications in monitory transaction systems like banks. However one of the major challenges in this direction is the capability of the system to detect skilled and unskilled forgery. Many cases of bank check forgeries have been reported. Most of the offline signature verification system adopts recognition(More)
In this paper, a low-power structure for shift-and-add multipliers is proposed. The architecture considerably lowers the switching activity of conventional multipliers. The modification to the multiplier which multiplies A by B include the removal of the shifting register, direct feeding of A to the adder, bypassing the adder whenever possible, using a ring(More)
