A Low Cost Highly Responsive Motion Sensing Surveillance System with Active Alerts using GSM Technology
Abstract
The aim of this work was to develop a smart sensor based monitoring system for indoor environments. This paper shows the implementation of a low-cost surveillance system using a Passive Infrared Motion Sensor. A low cost highly responsive motion sensing surveillance system with active alerts using GSM technology was designed around an eight bit microcontroller and covers an area (upto 6m) for detection. It senses the signal generated by PIR sensor detecting the presence of an unauthorized person at any time interval. Detecting the presence of an intruder, the system triggers an alarm followed by SMS and calls to some predefined numbers through a GSM modem. The system is well tested and found highly responsive.

Grid connected photovoltaic using multi level inverter
Abstract
This paper presents Photovoltaic (PV) connected to single phase grid based on maximum power point tracking .paper related with how to solve problems caused by unconformity phenomena as like partial shading condition (PSC) which the photovoltaic always be in most time .In order to enhancing the efficiency of tracking global maximum power point under partial shading condition (PSC) particle swarm optimization MPPT technique is approached.The
paper studys photovoltaic (PV) cell which is modeled as two diodes under the variation of irradiation and temperature (partial shading conditions) by using two different MPPT methods called particle swarm optimization (PSO) and incremental conductance method (IC) .The particle swarm optimization is one of the artificial intelligence method used to detect MPPT. The efficiency of PSO is higher than any traditional method such as IC. The efficiency of each method are shown in matlab simulation to show the advantage of detecting the optimal power point in all cases. The particle swarm optimization represent lower energy losses and reach max power point more quicker than incremental conductance method specially in the partially shading conditions. Both of two MPPT methods feed the input of the grid tied inverter with the determined DC bus voltage.

Simulation of FACTS Reactive Power via Static VAR Compensator
Abstract
This work presents a review of comparison of different FACTS controllers in the power system for stability enhancement. VAR compensation is defined as the management of reactive power to improve the performance of ac power systems. The focus of this research is simulation of single phase TCR/TSC Static Var Compensator to solve voltage regulation and system dynamic performance deficiencies. SVC is thyristor based controller that provides rapid voltage control to support electric power transmission voltages during immediately after major disturbances. Voltage stability, voltage regulation and power system stability, damping can be improved by using these devices and their proper control. Static Var Compensator (SVC) and capacitor bank improves the overall response of the system. The simulation results confirm the competitive dynamic response of the system using capacitor bank and SVC.

Physiochemical Characterization of B20 Bio-diesel from Arachis Hypogaea Oil as Alternative Fuel for Marine Diesel Engines
Abstract
Abstract:
For decades, research has scaled up in the production of an eco-friendly and efficient alternative fuel, that can be used in place of regular fossil fuel in marine diesel engines. This research work deals with the production of biodiesel B20 from Arachis Hypogaea oil, through trans-esterification process; a mixture of 20% Biodiesel and 80% Petroleum Diesel, for use in marine diesel engines. The results indicated a better performance characteristics, when the physical and chemical properties of the produced B100 and B20 blend was compared with B100 standard and Petroleum Diesel. From the research, it was concluded that B20 biodiesel blend can be used as an alternative fuel for marine diesel engines without any form of engine modification.
