Abstract: Hybrid Renewable Energy Resource System (HRES) is made up of PV, Wind and Battery. PV and Wind inputs are irradiance and Wind in which energy is generated. The battery is used as an energy storage unit to store most of the energy produced and can be used to meet the need for load under critical and environmental conditions. Unified Power Quality Controller to reduce power quality related issues such as sag, swell, harmonics etc. in the HRES system connected mainly owing to the non-linear load condition. So this paper proposes a Lightning Search Algorithm (LSA) with Unified Power Quality controller (UPQC) to solve PQ problems in the HRES system. The results obtained specify that the proposed LSA algorithm has several advantages in various.......

Abstract: Metal Oxide Semiconductor Field Effect Transistor (MOSFET) has been of crucial importance for the progress of nanoelectronics technology. Silicon on insulator (SOI), a new technology of MOSFET transistors, helps in miniaturization and decrease of short channel effects. A two dimension device simulation is performed to investigate the kink effect of partially depleted SOI MOSFET using Silvaco TCAD tools.This paper demonstrates a method for reducing the kink effect present in the current-voltage output characteristics of
partially depleted SOI MOSFET. In this method, the thickness of gate oxide for the device is reduced. Results obtained through simulations indicate that the proposed method, while still maintaining major advantages obtained by conventional SOI structure, can eliminate the kink effect.

Abstract: Offshore equipment and facilities, with the platform in focus, are some of the most capital intensive asset costing millions and/or billions of dollars to setup. The use of Ineffective security measures on offshore platforms can result in vulnerability of huge assets, internal and external threat oil production theft as regards to pipe line vandalism, gas leakage, rise in temperature, fire outbreak, etc. Since other traditional means of security such as watch by a human-being' have been found to be ineffective as the performance of the personnel on guard depends on his motivation, fatigue and concentration and skill level. This work aims at developing an automated electronic system tailored to effectively provide security and surveillance for equipment and facilities on offshore platforms against.....
