Introduction

Abstract: Photochemistry and photophysics of coordination compounds is developing at a very fast face. It deals with electron transition/transfer from ground state to exicted state and the change in various properties of the coordination compounds due to this charge transfer of different types (MLCT, LMCT, LLCT, and ILCT) have been discussed along with photophysical and photochemical deactivation processes and effect of solvent polarity on change transfer bands with variety of application of this emerging fields. Various photochemical reactions of complexes have been classified with examples as photoisomerization, ligand exchange, photoaquation, photoanation, photosubstitution, photoredox, photorecemination, etc.

Microgrid Energy Management Strategy for Low Dynamics Load Applications Using Simulink

Abstract: This paper presents an energy management strategy for microgrid consisting of photovoltaic, wind energy conversion system, battery, fuel cell, and electrolyzer system. Rule-based energy management strategy is designed to meet efficiently the slow varying residential load demand of rural households within the individual source limits. Simulation is carried out using MATLAB. Simulation results show that the developed energy management strategy is able to meet the instantaneous load demand in varying irradiance, wind speed, and load conditions keeping the battery state of charge and electrolyzer hydrogen pressure in allowable limits.

Effect of Temperature on Gate Leakage Current in P4 and P3 SRAM Cells at Deep Sub-micron CMOS Technology

Abstract: The explosive growth of battery operated semiconductor devices has made low-power design a priority in recent years. The effect of temperature on the leakage currents is coming as a future challenge in the high density CMOS based portable mobile multimedia rich applications. In this paper the standby leakage power analysis at different operating temperature for the Conventional 6T SRAM, P3 SRAM and P4 SRAM cell has been carried out. It has been observed that for 6T SRAM there is an increase in standby leakage power with increase in temperature and the gate leakage current is found to be reduced with temperature variations, but this effect of temperature variation is found to be significantly lowered in P3 and P4 SRAM cells due to p-MOS stacking. The design simulation has been performed on CMOS deep sub-micron technology node, 45nm, at VDD=0.7V and 0.8V, for n-MOS and p-MOS threshold voltages as 0.24V and 0.224V, respectively on temperature range from -250C to +1250C.

A Comparative Study of Attacks, Security Mechanisms, Preventive Measures, and Challenges in Wireless Sensor Networks

Abstract: Research on Wireless Sensor Networks (WSNs) initiated during the Distributed Sensor Networks (DSN) program at the Defense Advanced Research Projects Agency (DARPA) at around 1980. During this tenure the ARPANET (Advanced Research Projects Agency Network) had been functional with more than 200 Universities and Research Institutes (Chong & Kumar, 2003). DSNs were assumed to have many spatially distributed low-cost sensing nodes that collaborated with each other but operated autonomously, with information being routed to whichever node was best able to use the information. The processing was mainly performed on minicomputers and the Ethernet was used for DSNs. The Potential of Sensor Network was identified in a Distributed Sensor Nets workshop in 1978 organized by DARPA (Wang & Balasingham, 2010). DARPA launched research program called SensIT (Kumar & Shepherd, 2001) which provided the present sensor networks with new capabilities such as ad hoc networking, dynamic querying and tasking, reprogramming and multitasking. The IEEE defined ZigBee (IEEE 802.15.4) standard for low expense and high capabilities sensor network with having low data rates. The ZigBee standard specifies a suite of high level communication protocols for WSNs.
