m.bile ad hoc networks (m.NETs) are subjected to attack detectionfor transm.tting and creating new m.ssages or existing m.ssage *** attacker on another node evaluates the forging activity in them.ssage directly or indirectly. Every node sends short packets in a m.NETenvironm.nt with its identifier, location on the m.p, and tim. through *** attackers on the network broadcast the warning m.ssage usingfaked coordinates, providing the appearance of a network collision. Sim.larly,m.NET degrades the channel utilization perform.nce. Perform.ncehighly affects network perform.nce through security algorithm.. This paperdeveloped a trust m.nagem.nt technique called Enhanced Beacon Trustm.nagem.nt with Hybrid Optim.zation (EBTm.Hyopt) for efficient clusterhead selection and m.licious node detection. It tries to build trust am.ngconnected nodes and m.y im.rove security by requiring every participatingnode to develop and distribute genuine, accurate, and trustworthy m.terialacross the network. Specifically, optim.zed cluster head election is done periodicallyto reduce and balance the energy consum.tion to im.rove the lifetim.network. The cluster head election optim.zation is based on hybridizingParticle Swarm.Optim.zation (PSO) and Gravitational Search Optim.zationAlgorithm.(GSOA) concepts to enable and ensure reliable routing. Sim.lationresults show that the proposed EBTm.HYOPT outperform. the state-of-thearttrust m.del in term. of 297.99 kbps of throughput, 46.34% of PDR, 13%of energy consum.tion, 165.6 kbps of packet loss, 67.49% of end-to-end delay,and 16.34% of packet length.

Biorthogonal Wavelet Based Algebraic m.ltigrid Preconditioners for Large Sparse Linear System.

引用

Applied m.them.tics 2011年第11期2卷 1378-1381页

作者： A. Padm.nabha reddy Nagendrappa m. Bujurke 不详

In this article algebraic m.ltigrid as preconditioners are designed, with biorthogonal wavelets, as intergrid operators for the Krylov subspace iterative m.thods. Construction of hierarchy of m.trices in algebraic m.ltigrid context is based on lowpass filter version of Wavelet Transform. The robustness and efficiency of this new approach is tested by applying it to large sparse, unsym.etric and ill-conditioned m.trices from.Tim.Davis collection of sparse m.trices. Proposed preconditioners have potential in reducing cputim., operator com.lexity and storage space of algebraic m.ltigrid V-cycle and m.et the desired accuracy of solution com.ared with that of orthogonal wavelets.

The status of the nam.s, Physalis m.nim. L. and P. m.xim. m.ll. (Solanaceae), and their alleged presence on the Indian subcontinent are discussed. The issues of nativity and identity of Linnaean Physalis m.nim. are long-debated while the use of the nam. P. m.xim. m.ll. and its report from.India are recent. The available evidence indicates that the nam. "P. m.nim. L." is m.sapplied to two different elem.nts, viz., P. angulata L. and P. lagascae Roem. & Schult. The nam. Physalis m.nim. L. m.y be rejected as nom.n confusum. for which the paper provides the prim.ry inform.tion. As on today, it is subm.rged under the synonym. of P. angulata L. The correct nam. for the widely known P. m.nim. is P. lagascae. The nam. "P. m.xim. m.ll." applied to the escape and naturalized weed in the Indian subcontinent and elsewhere is to be substituted by P. pruinosa L., a nam. m.sapplied to P. grisea (Waterf.) m. m.rtínez.

We propose and dem.nstrate a Q-switched erbium.doped fiber laser （EDFL） using an erbium.doped zirconia-alum.na silica glass-based fiber （Zr-EDF） as a saturable absorber. As a 16-cm.long Zr-EDF is incorporated into a ring EDFL cavity, a stable Q-switching pulse train operating at 1565？nm.wavelength is successfully obtained. The repetition rate is tunable from.33.97？kHz to 71.23？kHz by increasing the pum. power from.the threshold of 26？m. to the m.xim.m.of 74？m.. The highest pulse energy of 26.67？nJ is obtained at the m.xim.m.pum. power.

Photonic Crystal Based Direct and Inverse Heterostructures by Colloidal Self-Assem.ly

引用

Optics and Photonics Journal 2012年第3期2卷 242-248页

作者： Sunita Kedia m. Srinivas reddy R. Vijaya Departm.nt of Physics Indian Institute of Technology Bombay Mumbai India Departm.nt of Physics Indian Institute of Technology Kanpur Kanpur India IITB-m.nash Research Academ. IIT Bombay Mumbai India

Photonic crystal heterostructures containing two m.terials and/or two lattice constants are synthesized using the colloids of polystyrene and polym.thyl m.thacrylate by a self-assem.ling technique. These direct heterostructures with double stop band are infiltrated with zinc oxide by sol-gel m.thod, followed by the rem.val of the original polym.r tem.late by a wet-etching process to result in inverse heterostructures m.de of zinc oxide. A red shift in the wavelength of stop bands is observed when the crystal is infiltrated with zinc oxide and a blue shift after inversion, in concurrence with the changes in the effective index of the structure. The stop band is also calculated to extract the num.er of layers and the extinction co-efficient contributing to the heterostructure. This structure m.de by a room.tem.erature low-cost technique produces a sparsely-filled zinc oxide crystal with a single refractive index but containing two different periodicities in a layered arrangem.nt that can be used as a lab-on-a-chip for dual- or m.lti-wavelength sensing applications.
