Mechanics of corrosion of two TRIP-assisted steels designated as A (having no Cr and Cu content) and B (having higher Ni, Cr and Cu content) heat treated at different condition to alter micro-structure phases. After two TRIP-assisted steels have been studied under the simulated condition of sea atmosphere in the laboratory scale in different level of salinity under the influence of neutral pH as well as exposing them in real sea water condition by using electrochemical test. Micro-structural characterization of Pre & post corrosive samples and quantitative phase analysis were carried out to arrive at heat treatment-structure-properties co-relation to get knowledge about mechanics of TRIP-assisted steels in different NaCl solutions.

Wireless Sensors Network consists of irreplaceable nodes after being deployed with limited energy resources. The data gathering protocol needs more realistic power consumptions model to estimate the network performance for various pervasive and ubiquitous applications. In this paper we have implemented the chain based and shortest hop data gathering and routing protocols that demonstrate how realistic power model assumptions can affect the system performance in comparison with the results obtained by considering the first order radio model. We formulated a data sheet which gives details of the energy required to transmit data packets on distance basis incorporating Log Normal Shadowing Model for obtaining the received signal strength. We also justified the reason to eradicate the power levels which are unnecessary and gives rise to complications. Moreover we have observed a comparative study of the proposed method in TinyOS platform while running the simulation in TOSSIM for realistic comparison of our model. Copyright © 2011 ACM. Source

Wireless Sensor Network (WSN) is constrained by limited available energy for data communication. Utilization of energy and enhancing network lifetime is a challenging task for the next generation wireless sensor network. In this paper we have designed an algorithm that performs the routing with low energy consumption. We have experimentally optimized the number of clusters that should be formed for escalating the lifetime of the network with provisions made to include equal number of nodes in each cluster. Our analysis and simulation results show that with realistic radio model we have achieved better load balance than several existing protocols, like LBEERA, HDS, SHORT, PEGASIS, LEACH and BINARY. A suitable node deployment strategy was adopted for ensuring wireless connectivity between each node. Moreover we have made simulations in NS-2 which supports our propositions to a greater extend. © 2011 Springer-Verlag. Source

This paper presents studies on the influence of Distributed Generation (DG) on congestion management with a proposed 'Line loading Index'. Specific grid locations are examined to study the influence of DG penetration on congestion. From competitive electricity market standpoint, DGs have great value when they reduce line congestion and improves bus voltage profile of most congested buses in particular locations and at particular times when feeders are heavily loaded. A case study on modified IEEE 14 bus test system indicates that the penetration of distributed generators can be an effective solution to reduce of power losses. The influence of DG on bus voltage profile and line losses has also been demonstrated in a modified IEEE 14 bus test system. © 2012 IEEE. Source

In this paper the analysis of circular slot and triangular slot loaded equilateral triangular microstrip antenna (ETMSA) is shown. It is observed that two shorted pin nearer to the two vertexes of ETMSA produces dual resonance frequencies with circular polarization (CP). Circular slot loading in between probe position and one shorted vertex widened the gap between two resonance frequencies. The variation of frequency gap between two resonance frequencies becomes nonlinear in character when the radius of circular slot is increases beyond 2.5mm.This nonlinearity is also demonstrated using a triangular slot of varied arm length. A comparative study is shown for different substrate permittivity. © 2013 IAMOT. Source
