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 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.

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 new framework allows one to examine how likely a traditional power producer is to switch to more efficient fuel under various relevant price risk factors. The results show that the carbon emission price and natural gas price stand out as the two most important determinants for an economically justifiable fuel conversion strategy. The impact of coal and electricity prices is less significant. © 2016 Elsevier Inc.

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.

Laser speckle contrast imaging (LSCI) provides a noninvasive and cost effective solution for in vivo monitoring of blood flow. So far, most of the researches consider changes in speckle pattern (i.e. correlation time of speckle intensity fluctuation), account for relative change in blood flow during abnormal conditions. This paper introduces an application of LSCI for monitoring wound progression and characterization of cutaneous wound regions on mice model. Speckle images are captured on a tumor wound region at mice leg in periodic interval. Initially, raw speckle images are converted to their corresponding contrast images. Functional characterization begins with first segmenting the affected area using k-means clustering, taking wavelet energies in a local region as feature set. In the next stage, different regions in wound bed are clustered based on progressive and non-progressive nature of tissue properties. Changes in contrast due to heterogeneity in tissue structure and functionality are modeled using LSCI speckle statistics. Final characterization is achieved through supervised learning of these speckle statistics using support vector machine. On cross evaluation with mice model experiment, the proposed approach classifies the progressive and non-progressive wound regions with an average sensitivity of 96.18%, 97.62% and average specificity of 97.24%, 96.42% respectively. The clinical information yield with this approach is validated with the conventional immunohistochemistry result of wound to justify the ability of LSCI for in vivo, noninvasive and periodic assessment of wounds.
