The capability of various metals used in optical fibre-based surface plasmon resonance (SPR) sensing is studied theoretically. Four metals, gold (Au), silver (Ag), copper (Cu) and aluminium (Al) are considered for the present study. The performance of the optical fibre-based SPR sensor with four different metals is obtained numerically and compared in detail. The performance of optical fibre-based SPR sensor has been analysed in terms of sensitivity, signal-to-noise (SNR) ratio and quality parameter. It is found that the performance of optical fibre-based SPR sensor with Au metal is better than that of the other three metals. The sensitivity of the optical fibre-based SPR sensor with 50 nm thick and 10 mm long Au metal film of exposed sensing region is 2.373 μm/RIU with good linearity, SNR is 0.724 and quality parameter is 48.281 RIU -1. The thickness of the metal film and the length of the exposed sensing region of the optical fibre-based SPR sensor for each metal are also optimized. © Indian Academy of Sciences.

Demand side management (DSM) is a growing concept around the world, particularly in urban India, recently due to presence of time of day (TOD) tariffs for the large commercial and industrial customers. Residential customers are not exposed to TOD tariff structure so far in India. This encourages commercial and industrial customers to schedule their flexible loads as per TOD tariff to extract maximum benefit of it and helps utilities to reduce their peak load demand and reshape the load curve. For efficient DSM implementation, this paper presents a multiobjective DSM solutions based on integer genetic algorithm to benefit both utilities and consumers. The proposed algorithm provides new directions on effective implementation of DSM techniques for Indian utilities. Simulations were carried out on Indian practical distribution system with large commercial and industrial loads. The simulation results of the proposed algorithm shows that the presented DSM technique comprehends reasonable savings to both utility and consumers simultaneously, while reducing the system peak. © 2013 Elsevier Ltd.

There are quantum states of light that can be expressed as finite superpositions of Fock states (FSFS). We demonstrate the nonclassicality of an arbitrary FSFS by means of its phase space distributions such as the Wigner function and the Q-function. The decoherence of the FSFS is studied by considering the time evolution of its Wigner function in amplitude decay and phase damping channels. As examples, we determine the nonclassicality and decoherence of generalized and reciprocal binomial states. © 2013 Elsevier B.V. All rights reserved.

Amalgamation of nanotechnology and biology has opened new horizons for controlled synthesis of nanomaterials of nano and micro-lengthscales for diverse sensing, catalytic and electromechanical applications. Inspired from nature and driven by the need to have nanostructures of desired morphology, microbial architecture has been exploited as a template in the present work. Biocompatible 1-D gold microwires, generated by assembly of amino acid functionalized AuNPs over the proliferating fungal hyphae, served as potential microelectrodes for electron transfer between enzyme and electrode surface. Delocalization of electrons over longer length scales, large surface area provided by assembled AuNPs and high biocompatibility yielded excellent analytical performance characteristics with high sensitivity of 43.2 μA/mM/cm(2) with standard deviation of 0.88% and wide linear range from 5 μM to 20 mM of glucose. The gold microwires thus generated demonstrate appreciable repeatability over 20 cycles in a cyclic voltammogram, and reproducibility with root mean square deviation as low as 1.3%. High stability and biocompatibility attribute these microwires with myriad potential biosensing and catalytic applications in varied domains. © 2013 Elsevier B.V. All rights reserved.

Since the late 1980s the world is working towards connectivity and convergence. In the last three decades, the convergence of information resources has happened. However to achieve a true convergence the information assets have to be shared, used and executed fruitfully by the various gadgets which we use in our daily lives. Internet of Things is a concept which leverages on the power of networks to create ubiquitous sensor-actuator networks. With the advent of the cloud technologies, the concept of IOTs can be integrated with even the basic elements having limited computing power. This paper aims to evaluate the possibilities offered by integrating the two concepts of IOTs and Cloud Computing. © 2011 IEEE.
