An attempt has been made in this paper to reveal the trends and challenges in optimization techniques for operating and controlling the Microgrid, a controllable part of the smart grid. The Operation and control of Microgrid clearly fits into the broad area of multi-objective optimization problem. A critical analysis of the through literature review indicates that the alternative intelligent methods as compared to the slower conventional methods are showing better promise in the area of optimization. The latest trend shows the shift towards computational alternatives from the traditional iterative techniques (gradient based methods) due to the need of deriving near-optimum results in short periods of time. The computational alternatives include evolutionary, heuristic, and nonclassical algorithms. © 2012 IEEE.

We have studied nuclear structure and reaction properties of Ne, Mg and Si isotopes, using relativistic mean field (RMF) densities, in the framework of Glauber model. Total reaction cross-section σR for Ne isotopes on 12C target have been calculated at incident energy 240 MeV. The results are compared with the experimental data and with the recent theoretical study [W. Horiuchi et al., Phys. Rev. C 86, 024614 (2012)]. Study of σR using deformed densities have shown a good agreement with the data. We have also predicted total reaction cross-section σR for Ne, Mg and Si isotopes as projectiles and 12C as target at different incident energies. © 2014 World Scientific Publishing Company.

A standard algorithm for LMS-filter simulation, tested with several convergence criteria is presented in this paper. We analyze the steady-state mean square error (MSE) convergence of the LMS algorithm when random functions are used as reference inputs. In this paper, we make a more precise analysis using the deterministic nature of the reference inputs and their time-variant correlation matrix. Simulations performed under MATLAB show remarkable differences between convergence criteria with various value of the step size. © 2010 American Institute of Physics.

The utilization of solid waste is the challenge for the civil and environmental engineers to utilize the waste from different industry to excel the sustainable development, and in the same time, it is matching with the cost concern of the present materials. Copper slag is a by-product obtained during smelting and refining of copper. The waste copper slag can be used as abrasive tools, road construction, and ballast. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. One of the greatest potential applications for reusing copper slag is in cement and concrete production. Many researchers have investigated the use of copper slag in the production of cement, mortar, and concrete as mixed with lime stone powder, dust, cement replacement, use as partial replacement of coarse, and fine aggregates. The use of copper slag in cement and concrete provides potential environmental as well as economic benefits for all related industries, particularly in areas where a considerable amount of copper slag is produced. This paper reviews the application area of copper slag and its allowable use in different activities. © 2014, Springer Japan.

Cr-doped CdSe nanoparticles have been synthesized by solvothermal technique. The effect of doping on structural, morphological, optical and magnetic properties has been investigated. According to the X-ray diffraction (XRD) study, with the increases in Crdoping concentration in CdSe, the lattice contraction takes place and the structure gets strained whereas the morphological study shows that with increase in Cr-doping particle size decreases. UV-Vis spectroscopy clearly shows blue-shift in the optical band-gap. Pure CdSe nanoparticles are diamagnetic in nature, but, however, with increases in Cr-content (0 - 5 %) in CdSe, they exhibit ferromagnetic behaviour. These synthesised nanoparticles are dilute magnetic semiconductors and are very promising candidates for 'Spintronic' device applications.
