Biom.tric devices provide secure m.chanism.towards gaining access. One of the Biom.tric features is Face and the system.im.lem.nted is Face Recognition system. The Classical Face Recognition System.is im.lem.nted with Principal Com.onent Analysis and is successful. PCA is a linear m.thod of extracting the features in a lower dim.nsion space and is severely affected by the Pose and surrounding illum.nation variation. To im.lem.nt effective face recognition system. pose variation is to be considered and the problem.is well addressed with Kernel PCA (nonlinear PCA). KPCA extracts features in a higher dim.nsion space, there by the system.is rugged to pose variation. The illum.nation variation is accounted for capture range of the front end device and its surrounding and is not dealt in KPCA. In this work Singular Value Decom.osition is used to deal with surrounding illum.nation and wavelets are em.loyed to aid the KPCA in capturing the m.lti Scale Features there by m.king the System.robust to pose and illum.nation variation. To show the perform.nce, the proposed m.thod is tested on YaleB, ORL Databases. The results obtained show the im.act of the m.thod and is com.ared with PCA, KPCA.

Second order statistical m.m.nt of the ordinary and extraordinary waves scattered by turbulent m.gnetized plasm. slab with electron density and m.gnetic field fluctuations is analytically calculated applying the perturbation m.thod. Num.rical calculations are carried out for the anisotropic Gaussian fluctuation spectrum.at different anisotropy factor and the angle of inclination of prolate irregularities with respect to the external m.gnetic field. Phase portraits of correlation function of the phase and am.litude fluctuations of scattered radiation are constructed. It is shown that correlation between ordinary and extraordinary wave decreases in proportion to the anisotropic factor. © 2011 IEEE.

International Journal of computer science Issues 2011年第5 5-2期8卷 314-317页

作者： Santhanam. T. Radhika, S. PG and Research Department of Computer Science D. G. Vaishnav College Chennai India Department of Computer Applications R. M. K. Engineering College Tiruvallur Dt. TN India

Im.ge processing operations can be categorized into three m.jor categories: im.ge enhancem.nt, im.ge com.ression and im.ge restoration. The objective of im.ge enhancem.nt is to im.rove the insight of the inform.tion in im.ges for hum.n viewing or to be used as a preprocessing tool for other im.ge processing techniques. Filtering techniques play a crucial role in enhancing the quality of an im.ge. This article explores the possibility of using an Artificial Neural Network for im.ge noise classification followed by the suitable filter classification. Probabilistic Neural Network strikes a superior perform.nce in identifying the noise as well as the suitable filter for the rem.val of a specific type of noise.

This paper analyzes the effect of driver size and num.er of shells on propagation delay for m.lti-Walled Carbon Nanotubes (m.CNT) interconnect at 22nm.technology node. An equivalent circuit m.del of m.CNT is used for estim.tion and analysis of propagation delay. The delay through m.CNT and Cu interconnects are com.ared for various driver sizes and num.er of m.CNT shells. The SPICE sim.lation results show that the m.CNT interconnect has lower propagation delay than Cu interconnects. The delay ratio of m.CNT to Cu decreases with increase in length for different driver size and num.er of m.CNT shells. However, the delay ratio increases with reduction in num.er of m.CNT shells. m.CNT is considered to be potential alternative to copper interconnects in future. m.CNT provides significant im.rovem.nt in propagation delay perform.nce over Copper for long (global) interconnects.

m.rden Electronics devices and electronic com.erce applications characterized by high volum. of transactions can't survive without an online support of computer system.and database technology. It gave birth to distributed real-tim. database system., a new form.of distributed database system. in which, transactions have deadlines or tim.ng constraints. Again, the rapid growth in m.bile Com.uting technology has provided a new platform.for Distributed Real Tim. Database System. (DRTDBS). DRTDBS are becom.ng ubiquitous and critical com.onent in m.bile environm.nt today. m.re recently, it em.rges as m.bile real tim. database system. (m.RTDBS) in the world of lightweight intelligent devices like palm.ops, cellular phones, car computers, sm.rt cards etc. Processing of transaction with m.bility as well as tim. constraints has opened up a new area of research with a num.er of design issues such as network connectivity, storage capacity, scheduling, data consistency, data replication & distribution, concurrency control & com.it processing, reliability, security, econom.cal aspect etc. In fact, this paper first discusses the perform.nce issues that are im.ortant to m.RTDBS, and then surveys the research that has been done so far. In fact, this study provides a foundation for addressing perform.nce issues im.ortant for the m.nagem.nt of very large m.bile real tim. data and pointer to other publications in journals and conference proceedings for further investigation of unanswered research questions. ©2010 IEEE.

We discuss the optical properties of one-dim.nsional, ultrathin, sub-wavelength, m.tallic gratings under transverse-m.gnetic (Tm. excitation, with particular attention to the phenom.non of quenched transm.ssion, recently highlighted in several optical experim.nts. In particular, we consider a grating with thickness com.arable or less than the m.tal skin depth, showing how the geom.trical properties of the grating can dram.tically m.dify its transm.ssion properties, often in a counterintuitive way. We study the role played by short-range(SR)/long-range(LR) surface plasm.ns (SPs) and localized SP resonances, showing that quenched transm.ssion m.st be ascribed to localized resonance effects, while long-range and short-range SPs play only a m.rginal role in this anom.lous effect. As an exam.le, we show the transm.ssion (T) in the plane (λ, θ) for a silver grating of thickness d=10 nm. slit aperture a=200 nm. width of the m.tal in the elem.ntary cell b=120 nm.and period Λ=a+b=320 nm.

A different m.chanism.to achieve total transm.ssion through an otherwise opaque screen, based on an inherently ultra-broadband tunneling m.chanism.that can span from.DC to the visible range is introduced. In this talk, the physics of this anom.lous tunneling phenom.non which is in m.ny ways analogous to regular Brewster transm.ssion through a dielectric etalon, despite the m.tal opaqueness is discussed. In addition, the potential application of these effects to produce novel polarization filters, energy concentrators and absorbers is also discussed.

This research paper is about shortest path algorithm. of routing in transportation networks. Efficient m.nagem.nt of networks requires that the shortest route from.one node to another is known. This research project also focuses in finding the shortest reliable path algorithm. We need to find the path distance from.the source to destination which is reliable and found in an optim.zed way considering the network constraints. Different testing m.thods are done for getting the accurate results.
