Video has been an important media for communications, education and entertainment for many decades. Streaming video over the distributed environment is extremely popular, because of its higher availability, efficiently in playback delay and scalable load management. Many applications like e-learning, Skype, YouTube and games, are require simultaneous streaming of video from several sources to a...
Many cells exhibit large-scale active circulation of their entire fluid contents, a process termed cytoplasmic streaming. This phenomenon is particularly prevalent in plant cells, often presenting strikingly regimented flow patterns. The driving mechanism in such cells is known: myosin-coated organelles entrain cytoplasm as they process along actin filament bundles fixed at the periphery. Still...
3D-video systems allow a user to perceive depth in the viewed scene and to display the scene from arbitrary viewpoints interactively and on-demand. This paper presents a prototype implementation of a 3D-video streaming system using an IP network. The architecture of our streaming system is layered, where each information layer conveys a single coded video signal or coded scene-description data....
In this paper, we propose a centralised Peer-to-Peer (P2P) streaming over hybrid wireless networks to mitigate the congestion at the Access Point (AP) in Wireless Local Area Networks (WLANs). In our proposed architecture, an adaptive receiver-driven mechanism is used to coordinate the streaming from multiple senders. We also propose a peer handoff scheme and an AP handoff scheme for video strea...
The mobile phone plays an entertainment role in human life with the help of heterogeneous network by accessing multimedia content. But users faces a certain problems while access multimedia like long buffering time and intermittent disruption due to gap between demand traffic and link capacity, along with time varying link condition. The proposed technique focus on providing adaptive video stre...
This paper deals with the measurement of acoustic particle velocity and acoustic streaming velocity in a closed-loop waveguide in which a resonant traveling acoustic wave is sustained by two loudspeakers appropriately controlled in phase and amplitude. An analytical model of the acoustic field and a theoretical estimate of the acoustic streaming are presented. The measurement of acoustic and ac...
Streaming music services have exploded in popularity in the past few years, variously raising optimism and concern about their impacts on recorded music revenue. Even if streaming displace sales, it may still raise overall revenue if the streaming payment is large enough in relation to the extent of sales displacement. We make use of the growth streaming during the years 2013-2015 to measure th...
Multiple Description (MD) and Layered Coding (LC) are two source-coding approaches proposed for adaptive and robust video streaming over lossy networks. Both streaming methods aim to improve the streaming quality by transmitting the generated multiple sub-bitstreams over partially link-disjoint paths. However, the achieved qualities heavily depend on the media characteristics, path conditions a...
The growth of wireless LANs has brought the expectation for high-bitrate streaming video to wireless PCs. However, it remains unknown how to best adapt video to wireless channel characteristics as they degrade. This paper presents results from experiments that stream commercial video over a wireless campus network and analyze performance across application, network and wireless link layers. Som...
Cytochalasin B reversibly inhibits cytoplasmic streaming in both Nitella and Avena cells. Colchicine, on the other hand, has no effect on streaming in either plant; nor does colchicine prevent the recovery of streaming after cytochalasin is withdrawn. The inhibition of protein synthesis by cycloheximide has no effect on either streaming itself or on the recovery of streaming after cytochalasin ...
