—Ad hoc networks are self-organizing multi-hop systems consisting wireless nodes which can communicate with each other without pre-existing infrastructure. Clustering has evolved as an important research topic in mobile ad hoc networks(MANETs) as it improves the system performance of MANET, in the presence of both mobility and a large number of mobile(More)

MAC layer design is critical for energy efficiency in wireless sensor networks. We present an approach to reduce the time spending on data moving. In our approach, a MAC layer needs to stripe off the network layer header and store a data frame received until receiving the next hop address from the network layer where a route look-up is executed. The amount(More)
The present study used the event-related potential technique to investigate the nature of linguistic effect on color perception. Four types of stimuli based on hue differences between a target color and a preceding color were used: zero hue step within-category color (0-WC); one hue step within-category color (1-WC); one hue step between-category color(More)
Energy efficiency is a critical issue for a MAC protocol in sensor networks. Thus much effort has been paid on research about the sleeping mode of MAC protocol. However, we found out that significant amount of energy is wasted when a data packet received by MAC is transferred to the network layer to get the next hop address by searching the routing table(More)
In this paper, the output feedback control problem for a genetic hypersonic vehicle is considered under the restriction that only the vehicle's velocity and altitude are measurable. High gain observers (HGO) are utilized to provide estimation signals for unmeasurable derivatives of the vehicle's velocity and altitude. A comprehensive stability analysis of(More)
The present study was carried out to investigate whether sign language structure plays a role in the processing of complex words (i.e., derivational and compound words), in particular, the delay of complex word reading in deaf adolescents. Chinese deaf adolescents were found to respond faster to derivational words than to compound words for(More)
