By the use of fossil based fuels in power generation units requires the consideration of the environmental pollution. A multiobjective particle swarm optimization technique for the solution of environmental economic power dispatch problem is proposed in this paper. Here EED problem is formulated a nonlinear multiobjective function as objective function by considering both equality and inequality constraints. The multi-objective optimization in power systems treats economic and emission as conflicting objectives, to get an optimal solution some reasonable trade off among these objectives are required. So in this paper, the power dispatch is formulated into a two-objective optimization problem, which is to minimize the fuel cost as well as emission simultaneously.
Keywords : Environmental/Economic (EED) dispatch, multiobjective optimization, particle swarm optimization, Pareto optimal solution, compromise factor.

Todays the need of home security alarm systems is on higher demand. As the numbers of crimes are increasing every day, there has to be something that will keep us safe. We are all aware of the high-end security systems are presented in the market but they are not easily available to alone. We therefore inferred to provide a solution by constructing a cost eligible electronic system that has the capability of sensing the motion of the unasked person and setting off the alarm. The basic idea behind this project is that Security is the main concern for everyone. Everyone wants to live securely in his/her house. Everyone wants themselves to keep innocuous or secure from various incidents for example theft in their home or accidents caused due to LPG gas leakage or due to fire in their home. Now days many times we heard news about house robbery or theft in some houses, bungalows, flats. These robberies or thefts take place when no one is in home or in other case we find that robbery is happen even if people are in their homes. Other bad news we heard is about accidents are happened or blast cause, because of LPG gas cylinder Smart Home can be also called as leakage. The second method sends SMS which uses GSM Module (sim 900c) and lpc2148 Arm processor, sensors, limit switch and buzzers.
