This paper presents the optimized design process of intake systems by using dual duct intake system. The intake system is especially important system which creates the power and provides the air at the engine. And it has another role to reduce engine noise. So, many methods are used to reduce the intake noise. In this paper, we tried to improve engine power and reduce the noise by using dual duct intake system. This research shows that the result of practical test is remarkably consistent with CAE analysis.

This paper presents an efficient overlay multicast routing protocol (ROMP) and its architecture. ROMP using GPS and region map stands on the basis of scalable 2-tiered multicast architecture and maintains a global overlay multicast tree through reactive fashion. With this approach, the coarse-grain location-awareness for an efficient overlay multicasting and the determination of hot-spot area for efficient data delivery are feasible. The simulation results show that the localized control packets of ROMP prevent the overlay control packets from squandering the physical network resources.
