in order to study of genetic diversity in 35 lentil genotypes in some morphophenological   traits, yield and yield components, and determine the relationships between different traits by multivariate statistical methods, an experiment was conducted as augmented design in 4 blocks in 2012. the results of descriptive statistics showed that many of traits had considerable variability. the results ...

Efficiency of Forward Error Correction (FEC) in packet switched networks strongly depends on the buffer size. Use of FEC in off-line streaming, offering large buffers, gives spectacular results; but real-time streaming puts hard restrictions on the buffer size leaving FEC helpless for combating long link failures on a single path route. Apart the buffering ax, there exists however another ortho...

Abstract This paper presents the use of a multi-objective diversity control oriented genetic algorithm (MODCGA) for solving a closed-loop time-optimal path planning problem. The MODCGA is a result of the integration...

Path Diversity Media Streaming over Best Effort Packet Switched Networks by Thinh P.Q. Nguyen Doctor of Philosophy in Engineering-Electrical Engineering and Computer Sciences University of California at Berkeley Professor Avideh Zakhor, Chair Recent years has witnessed phenomenal growth of the Internet. According to Internet Software Consortium, number of hosts has reached 171 millions in Janua...

Streaming media over best-effort networks is still an area rich in challenging problems, and many issues remain to be resolved in order to allow the deployment of large scale continuous media content delivery over the Internet. Recent works have addressed methods to cope with the poor quality of service of the Internet due to its best effort service. One promising technique is the use of distin...

Multiple Description Coding is a forward error correction scheme where two or more descriptions of the source are sent to the receiver over different channels. If only one channel is received the signal can be reconstructed with distortion D1 or D2. On the other hand, if both channels are received the combined information is used to achieve a lower distortion D0. Our approach is based on the Mu...

Network Losses due to congestion and node failures severely impair the performance of multimedia streaming on the Internet. In previous work [14], we proposed a content distribution mechanism based on k-DAGs, a special Directed Acyclic Graph (DAG) with k parents per receiver, exploiting path-diversity and rate-adaptation to improve the performance of multicast multimedia streaming. In this pape...

The recent advent of widely available broadband Internet access has resulted in an explosive growth of new video streaming applications and research into methods to efficiently support such applications over today’s Internet. Many approaches, including source and channel coding techniques, have been proposed to deal with the delay, loss, and timevarying characteristics of best-effort packet-swi...

Overlay routing has emerged as a promising approach to improve reliability and efficiency of the Internet. For one-hop overlay source routing, when a given primary path suffers from the link failure or performance degradation, the source can reroute the traffic to the destination via a strategically placed relay node. However, the over-heavy traffic passing through the same relay node may cause...
