Different users have different behavior and habits. When an ambient intelligence system is designed for a smart home environment, such difference in the user's activity patterns and preferences in environment settings has to be taken into account for the system to adapt to and satisfy the user. Automatic learning of the behavior and preferences of the user(More)

— Wireless Sensor Networks (WSNs) have inherent and unique characteristics. One of the most important issues is their energy constraint. Energy aware routing protocol is very important in WSN, but routing protocol which only considers energy has not efficient performance. Congestion management can affect routing protocol performance. Congestion occurrence(More)
The object of this study is evaluation of cadmium removal from industrial wastewater by electrocoagulation process. For this study a glass tank in 1.56 liter volume with four plate electrode was used to do experiments. The electrodes made of aluminum and connect to the positive and negative pole of DC power supply (bipolar mode). The tank was filled with(More)
In this paper, we considered solving approaches to flexible job shop problems. Makespan is not a good evaluation criterion with overlapping in operations assumption. Accordingly, in addition to makespan, we used total machine work loading time and critical machine work loading time as evaluation criteria. As overlapping in operations is a practical(More)
— Wireless Sensor Networks (WSN) have been noticed and researched nowadays. These new type of networks have unique characteristics. WSNs have different limitations such as computational power, storage capacity, energy source and etc. The main constraint of wireless sensor networks is energy. The energy source of sensor nodes is limited and not rechargeable.(More)
Biodiesel fuel, as fatty acid methyl ester is produced by esterification of plant oil or animal fat with methanol. This renewable fuel resource is an attractive alternative for the replacement of petroleum based fuels. Utilization of the whole cell as biocatalyst instead of free or immobilized enzyme is a new approach to reduce the catalysts costs in(More)

− In this paper, a new method based on Green's function theory and Fourier transform analysis has been proposed for calculating band structure with high accuracy and low processing time. This method utilizes sampling of potential energy in some points of crystal's unit cell with Dirac delta functions, then through lattice Fourier transform gives us a simple(More)
