This document describes Media-independent Pre-Authentication (MPA), a new handover optimization mechanism that addresses the issues on existing mobility management protocols and mobility optimization mechanisms to support inter-domain handover. MPA is a mobileassisted, secure handover optimization scheme that works over any link layer and with any mobility management protocol, and is most appli...

background:the dynamic binding capacity (dbc) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. optimization of the process criteria for maximum dbc avoids extra process scale-up and reduces the processing time, costs and protein loss. taguchi method is a simple usef...

In this paper, we consider the optimal design of photonic crystal band structures for twodimensional square lattices. The mathematical formulation of the band gap optimization problem leads to an infinite-dimensional Hermitian eigenvalue optimization problem parametrized by the dielectric material and the wave vector. To make the problem tractable, the original eigenvalue problem is discretized...

We introduce a wave front shaping protocol for focusing inside disordered media based on a generalization of the established Wigner-Smith time-delay operator. The key ingredient for our approach is the scattering (or transmission) matrix of the medium and its derivative with respect to the position of the target one aims to focus on. A specific experimental realization in the microwave regime i...

Growth of Spirulina platensis LN1 was observed using eight different media consisting of different combinations of Lonar lake water, N, P and K and Zarrouk medium composition under different incubation periods. Medium II was suitable on 9th day of incubation and medium III was suitable on 15th day of incubation for its growth whereas, 12th day of incubation was shown to be suitable for its grow...

Time-reversal (TR) methods provide a simple and robust solution to source imaging problems. However, for recovering a well resolved image of the source, TR requires a balanced illumination of the target from all angles. When acquisition is incomplete and a balanced illumination is not possible, the TR solution may not be adequate. In a previous paper, by formulating source imaging as an optimiz...

Systematic studies of mouse embryo culture beginning in 1949 led to an understanding of essential medium components for early mammalian embryos, and embryo culture from the zygote to the blastocyst stage was achieved in 1968. Since then, medium components that are either beneficial or detrimental for embryo culture have been identified. A variety of culture media that mimic the female reproduct...

Information overload has been studied extensively by decision science researchers, particularly in the context of task-based optimization decisions. Media selection research has similarly investigated the extent to which task characteristics influence media choice and use. This paper outlines a proposed study, which would compare the effectiveness of web-based online product review systems in f...
