Cloud computing is an emerging new technology that can be integrated with healthcare monitoring system. The current survey of all healthcare organizations shows that it needs the assist of cloud computing to store the patients PHI and to get help in emergency condition using cloud-based virtual server. For an effective monitoring system cloud uses BSN to monitor the patient health conditions. Here the cloud acts as a virtual server and stores the patient information in third party server which causes serious threats to security and privacy. The healthcare center contains various approaches which have been used to monitor the healthcare information based on cloud environment. The objective of this study is to discuss about various techniques and taxonomy about the current methods of cloud computing used in hospital healthcare monitoring system. Moreover the strengths and weaknesses of the healthcare monitoring system approaches are also discussed. © Springer Science+Business Media Singapore 2017.

We examine terahertz guided mode properties of a plasmonic waveguide comprising periodic corrugations along the direction of propagation as well as within the structures. We also analyse the slow light properties of the guided modes. © OSA 2016.

We discuss near-field coupling between the pair of split ring resonators (SRRs) in broadside coupled terahertz (THz) metamaterials and examine resonance split and tuning of resonances in such metamaterials system. The metamolecule design is comprised of two orthogonally twisted broadside coupled SRRs separated by a thin microscale polyimide layer. We analyze the interaction between the metalayers numerically and analytically by displacing the top resonator w.r.t. the bottom resonator both in the horizontal and vertical directions. The THz transmission through proposed configuration results in the split of fundamental resonances due to the resonance mode hybridization effect. In the case of successive horizontal displacements between the resonators, we observe a complete shift from the coupled to uncoupled state, however, in vertical displacements, we notice the transition from coupled to uncoupled state at much larger displacement. We employed a semianalytical transmission line model to understand and describe the coupling aspect between the bilayer resonators and found that it corroborates the numerical findings. The ability to tune resonance behavior that we have examined through this work, could be significant in the development of frequency tunable THz devices and build other promising applications such as THz modulators and antennas in the near future. © 1995-2012 IEEE.

We analyze plasmon induced transparency (PIT) in a planar terahertz metamaterial comprising of two C-shaped resonators and a cut-wire. The two C-shaped resonators are placed alternately on both sides of the cut-wire such that it exhibits a PIT effect when coupled with the cut wire. We have further shown that the PIT window is modulated by displacing the Cshaped resonators w.r.t. The cut-wire. A lumped element equivalent circuit model is reported to explain the numerical observations for different coupling configurations. The PIT effect is further explored in a metamaterial comprising of a cross like structure and four C-shaped resonators. For this configuration, the PIT effect is studied for the incident light polarized in both x and y directions. It is observed that such a structure exhibits equally strong PIT effects for both the incident polarizations, indicating a polarization independent response to the incident terahertz radiation. Our study could be significant in the development of slow light devices and polarization independent sensing applications. © 2017 Optical Society of America.

Interfacial wave solutions for a planar interface between two finite layers have been obtained within the framework of antiplane elasticity. Solutions are found to exist both for slipping contact and for bonded contact at the interface. Both the slip and bonded contact waves are found to be dispersive and multivalued. One family of slip and bonded contact waves is found with phase velocity in between the shear wave speeds of the two solids. It is also found that two families of slip and bonded contact waves exist with phase velocity greater than the shear wave speed of both solids. © 2017 by ASME.

This article examines the dynamics of the income-distribution pattern in India during the post-1991 economic reforms. It considers district-level per-capita income data across agriculture, manufacturing, services, and various constituent sub-sectors, and finds evidence in favour of a uniform process of growth across sectors and regions, which has helped to reduce poverty. In particular, the article finds that growth in agricultural income and access to finance are important for this. © 2015 Overseas Development Institute.

A right amount of disorder in the form of refractive index variation has been introduced to achieve transverse localization of light in 1D semi-infinite photonic lattices. Presence of longitudinally-invariant transverse disorder opens-up a new waveguiding mechanism. © OSA 2014.

Electromagnetic metamaterials (MMs) consisting of highly conducting sub-wavelength metallic resonators enable many unusual electromagnetic properties at user defined frequencies which are not permissible with the naturally occurring materials [1, 2]. Generally the electromagnetic properties of metamaterials are controlled by the design variation of the MM unit cell, often termed as meta-molecule, consisting of single or multiple metallic split ring resonators (SRRs). These metallic resonators are quite often termed as meta-atoms too. The near field electromagnetic coupling between these meta-atoms exhibits an important role in modulating the fundamental resonances of the metamaterials [3-5]. © 2016 IEEE.
