This paper proposes a novel method of structure-borne sound analysis and active force control, which combines interval mathematics and robust optimization theorems, to achieve vibration damping and noise reduction for enclosed cavity systems with bounded uncertainty. By introducing the interference principle of sound wave, responses under control can be obtained by solving finite element equations...
The hidden terminal problem is particularly common in wireless local networks (WLANs). It is the dominant factor to reduce throughput. In this paper, we develop a new method to improve throughput in WLANs with hidden terminals under the non-saturated condition. The hidden terminal problem may result in very large contention window size, so that much channel resource is wasted. Our method efficiently...
