this paper aims to assess the application of support vector machine (svm) regression in order to analysis flexible pavements. to this end, 10000 four-layer flexible pavement sections consisted of asphalt concrete layer, granular base layer, granular subbase layer, and subgrade soil were analyzed under the effect of standard axle loading using multi-layered elastic theory and pavement critical r...

Opportunistic data forwarding significantly increases the throughput in multi-hop wireless mesh networks by utilizing the broadcast nature of wireless transmissions and the fluctuation of link qualities. Network coding strengthens the robustness of data transmissions over unreliable wireless links. However, opportunistic data forwarding and network coding are rarely incorporated with TCP becaus...

| In wireless networks, the provision of QoS guarantees needs to address the limited capacity of the physical medium. Such an objective calls for the joint design and integration of the network layer, medium access control, and physical layer. Supporting Integrated Services at the network layer demands a multi-rate transmission scheme at the physical layer, whereas achieving high data throughpu...

This paper proposes an efficient scalable coding scheme with fine-grain scalability, where the base layer is encoded with H.26L, and the enhancement layer is encoded with PFGS coding. Motion compensation with adaptive block size has greatly contributed to the coding efficiency improvement in H.26L. In order to improve efficiency of the enhancement layer coding, an improved motion estimation sch...

Ensuring security at the physical layer in wireless communications is important and effective because it can omit upper-layer secure protocols in ad hoc or multi-hop relay transmissions, or it can enhance security together with upper-layer protocols. To realize this system, we have proposed a chaos-based multiple-input multiple-output (MIMO) transmission scheme that enables both physical-layer ...
