The current research work is focussed to prepare the nano composite surface layer by reinforcing TiB2 particles on 6061-T6 Aluminum Alloy via Friction Stir Processing (FSP). And also study the influence of nano sized reinforcement particles such as TiB2 (average size is 35 nm) on microstructure and mechanical properties of 6061-T6 Aluminum alloy based surface nano composite fabricated via FSP. The fabricated surface composites have been examined by optical microscope (OM) and scanning electron microscope (SEM) for dispersion of reinforcement particles, thickness of nano composite layer formed on the Aluminum alloy substrate and fracture features. The friction stirred zones were characteristically about the size of the rotating pin, namely width and depth of 8 mm and 4 mm respectively.The depth of surface nano composite layer is measured as 3683.82 μm along the cross section of stir zone of surface nano composite normal to the FSP direction. Microstructures of all the surface composites are revealed that the distribution of reinforcement particles in the nugget zone (NZ). It is observed that increase in the volume percentage of TiB2 reinforcement particle, the microhardness was increased up to 132 Hv and this value is higher than the as received Aluminum alloy's microhardness (104 Hv). It is also observed that at 4 volume percentage higher tensile properties exhibited as compared with the 2 and 8 vol.%. The observed mechanical properties were correlated with microstructure and fracture features. © 2017 Elsevier Ltd. All rights reserved.

In this current research work, the effect of tool rotational speed on micro structural and mechanical properties of Friction stir welded 5083 Aluminium alloy was studied. The welding parameters, especially tool rotational speed plays a major role in deciding the weld quality. It is observed that higher mechanical properties are obtained at a rotation speed of 710 rpm. It is also observed that the fine microstructure obtained at the above mentioned condition. The mechanical properties were observed & correlated with the microstructureand fracture features. © 2017 Elsevier Ltd. All rights reserved.

In this present research work, the effect of fine Post-weld Rapid cooling on Grain size and Mechanical properties of Friction Stir Welded AA 2014 was studied. The welding parameters and tool pin profile play major roles in deciding the weld quality. It is observed that the grain size is decreased to 2-4 μm (average size) bypost-weld rapid cooling with the mixture of dry ice and ethanol. It is also observed that mechanical properties are enormously improved. The observed grain size and mechanical properties have been correlated with microstructures and fracture features. © 2017 Elsevier Ltd. All rights reserved.

Power system state estimation is the important module in monitoring the power system network. The state estimator provides states of the power system by processing the measurements placed optimally across the power system network. However, temporary un-observability may occur due to unexpected loss of measurement devices or communication links. In the present paper, the reliability of the static state estimation has been tested under three different scenarios, viz. over-determined, critically determined, and under-determined systems. The state estimation problem has been solved using JADE-adaptive differential evolution algorithm utilizing both the conventional and the synchronized phasor measurements. From the test results it has been determined that the proposed technique determines the solution even when the power system is partially observable and also detects the un-observable buses present in the network. The results thus obtained using JADE have been compared with conventional weighted least square and improved self-adaptive particle swarm optimization-based SE techniques. On the bases of various performance indices, the results show the effectiveness, reliability, and accuracy of the proposed algorithm when compared to other state estimation techniques. © 2017 Springer-Verlag GmbH Germany

In the modern world, the most used material for construction buildings and to build infrastructure the most used material is concrete. and concrete is normally manufactured by mixing with ingredients such as cement, cores aggregates,fine aggregates,water,and mineral admixtures for latent concrete nowadays such as, fly ash,GGBS and also usage of super plasterers for improving strength of concrete.The materials used for concrete manufactures such as fine aggregates are found in nature and used by trimming them into required shape & size. Water is also available in nature and clan water is used,but cement is manufactured for raw materials available in nature.Normally the process of manufacturing of cement is very much energy consuming process.As some of the surveys said one tone manufacturing of cement produces nearly one tone of carbon dioxide.And which in turn produces green house gases which cause global warming. So if mainly cement could be replaces there may be some reduction in consumption of cement & which in turn reduces carbon dioxide production.So this will reduce global warming Instead of cement some cementations material can be used to replace cement, Some of the materials which can be replaces is that fly ash and GGBS.So using fly ash and GGBS potential replacement can be done with cement, But it is not possible to do replacement without cement. So some study is been made by replacing cement completely with fly ash and GGBS. © IAEME Publication.

Thyroid tissue samples, pathologically characterized as normal and malignant type, containing both the epithelial and stromal regions are prepared on two different glass slides. Polarized light scattering from these individual slides is used to record the intensity images by Polarimetric Imaging technique. These images are processed further to obtain Mueller intensity images respectively for normal and malignant tissue types. Polar decomposition of these Mueller intensity images results in obtaining Depolarization, Diattenuation, and Retardance images; their potentiality to understand the structural and morphological changes in the samples is reported for comparison. © 2017 IETE

In this paper a generalized approach is proposed for clustering a set of given documents or text files or software components for reuse based on the new similarity function called hybrid XOR function defined for the purpose of finding degree of similarity among two document sets or any two software components. We construct a matrix called similarity matrix of order n-1 by n for n document sets or software components by applying hybrid XOR function for each pair of document sets. We define and design the clustering algorithm which has its input as similarity matrix and output as a set of clusters formed dynamically as compared to other clustering algorithms that predefine the count of clusters and documents being fit to one of those clusters or classes finally. The approach carried out uses simple computations. © 2013 The Authors. Published by Elsevier B.V.

Reforms in undergraduate engineering curriculum to produce engineers with entrepreneurial skills should address real-world problems relevant to industry and society with active industry support. Technology-assisted, hands-on projects involving experimentation, design simulation and prototyping will transform graduates into professionals with necessary skills to create and advance knowledge that meets global standards. To achieve this goal, this paper proposes establishing a central facility, ‘Centre for Engineering Experimentation and Design Simulation’ (CEEDS) in autonomous engineering colleges in India. The centre will be equipped with the most recent technology resources and computational facilities where students execute novel interdisciplinary product-oriented projects benefiting both industry and society. Students undertake two projects: a short-term project aimed at an engineering solution to a problem in energy, health and environment and the other a major industry-supported project devoted to a product that enhances innovation and creativity. The paper presents the current status, the theoretical and pedagogical foundation for the centre's relevance, an activity plan and its implementation in the centre for product-based learning with illustrative examples. © 2016 SEFI

Mixed convection heat and mass transfer along a vertical plate embedded in a power-law fluid saturated Darcy porous medium with Soret and Dufour effects is studied. The governing partial differential equations are transformed into ordinary differential equations using similarity transformations and then solved numerically using shooting method. A parametric study of the physical parameters involved in the problem is conducted and a representative set of numerical results is illustrated graphically. © 2015 The Authors.
