This research employs a nondestructive, rapid, high accuracy and full-field material characterization platform which integrates quantitative laser ultrasound visualization system (QLUVS) with mechanical property mapping reconstruction algorithm. The QLUVS uses a pulsed laser generate acoustic waves with fast scanning mechanical to research two dimensional scanning goal and then detected with a ...

In order to achieve the integrated optimization in developing the big network system, this paper presented the concepts and principles of layered design method and collaborative development using of different tools firstly. Then we gave a recommended layered architecture for the distributed computing network system and also analyzed its pros and cons. At last, we extended the distributed comput...

In this work\ a new concept for a two!layered micro!channel heat sink with counter current ~ow arrangement for cooling of the electronic components is proposed[ The thermal performance and the temperature distribution for these types of micro channels were analyzed and a procedure for optimizing the geometrical design parameters is presented[ While the power supply system of the two!layered des...

Although layered coding solutions elegantly handle bandwidth heterogeneity among users in video conferencing, they also incur significant rate and complexity overheads. An alternative is partitioning the receiver sets and using non-layered coding for each group. In this paper, we investigate how to maximize the received video quality for both systems under uplink and downlink capacity constrain...

Multiparty video conferencing is getting increasingly popular on the Internet. However, bandwidth heterogeneity among users still presents an obstacle against delivering a high quality of experience. One natural solution to deal with this heterogeneity is through using layered coding. However, practical layered coders incur significant rate and complexity overheads compared to non-layered codin...
