Abstract

VCS is one of the recent emerging areas in image secret sharing, where one can easily encrypt and share the image in secure way and which can be decrypted through the human visual system without computation. In this project, this scheme is implemented for hiding image in a video stream using two in one image secret sharing scheme (TiOISSS) with two decoding options. It is based on Visual Cryptography Scheme (VCS) and Polynomial based image secret sharing scheme (PISSS) known as Newton‟s raphson method and comparing the same with already existing Lagrange‟s interpolation method. This comparison is made to show the reduction in file size of shadow image for faster transmission within a distributed multimedia system.

Abstract

Albizia lebbeck (L.) Benth belongs to the family Fabaceae (formerly Leguminaceae) and a member of subfamily Mimosaceae native to India. The various parts of this plant possess a wide range of pharmacological activities such as antimicrobial, analgesic, anti-inflammatory, immunomodulatory, anti-arthritic, antiasthmatic, antioxidant, antidiarrhoeal, anticonvulsant, mast cell stabilization, anti-anaphylactic, steroidogenic, nootropic, antifertility, antihistaminic, antitumor, antiulcer etc. The purpose of this review is to provide an overview of the diverse pharmacological activities of Albizia lebbeck (L.) Benth and collate the reported work by the researchers on this plant. The outcome claims that Albizia lebbeck (L.) Benth is a highly important medicinally active plant.

Abstract

A gel is colloid that is typically 99% by weight liquid. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. A major limitation is in the delivery of hydrophobic drugs. To overcome the limitation a novel approach i.e. an emulsion based approach is being used so that even a hydrophobic moiety can enjoy the unique properties of gels. When gel and emulsion are used in combined form the dosage form are referred as emulgel. Emulgels have emerged as one of the most interesting topical delivery system as it has dual release control system i.e. gel and emulsion. The presence of a gelling agent in the water phase converts a classical emulsion into an emulgel. Emulgels for dermatological use have several favorable properties such as being thixotropic, greaseless, easily spreadable, easily removable, emollient, non staining, water-soluble, longer shelf life, bio-friendly, transparent and pleasing appearance. The use of emulgel can be extended in analgesics and antifungal drugs.

Abstract

Even in well managed Large ISP networks, failures of links and routers are common. Due to these failures the routers update their routing tables. Transient loops can occur in the networks when the routers adapt their forwarding tables. In this paper, a new approach is proposed that lets the network converge to its optimal state without loops and the related packet lossless. The mechanism (OUTFC-Ordered Updating Technique with Fast Convergence) is based on an ordering of the updates of the forwarding tables of the routers and fast convergence. Typically we have chosen a Network consisting of routers and Link costs for simulation. Link failures are simulated. Avoiding transient loops in each case is demonstrated, by constructing a Reverse Shortest Path Tree (RSPT).
