This memo describes extensions for the RTP payload format defined in RFC 3640 for the transport of MPEG Surround multi-channel audio. Additional Media Type parameters are defined to signal backwardscompatible transmission inside an MPEG-4 Audio elementary stream. In addition, a layered transmission scheme that doesn’t use the MPEG-4 systems framework is presented to transport an MPEG Surround e...

Fluvial geomorphic processes structure habitats important to stream fishes. We determined relationships between densities of smallmouth bass (Micropterus dolomieu) and ecoregions, watershed and reach morphology, and stream habitat in eastern Oklahoma, USA. Watershed and reach morphology were measured at 128 stream sites, and stream habitat and smallmouth bass abundance were measured in 1800 cha...

Cameras that can acquire a continuous stream of depth images are now commonly available, for instance the Microsoft Kinect. It may seem that one should be able to stream these depth videos using standard video codecs, such as VP8 or H.264. However, the quality degrades considerably as the compression algorithms are geared towards standard three-channel (8-bit) colour video, whereas depth videos...

mmWave communication typically resorts to beamforming in order to overcome the unfavorable propagation conditions in the high frequency bands. The directional transmission established using beamforming is beneficial also in terms of reducing the effective channel impulse response (CIR) and, correspondingly, the required guard periods in a block transmission scheme. While this effect has been in...

A new error-resilient JPEG2000 wireless transmission scheme is proposed. The proposed scheme exploits the ‘progressive by quality’ structure of the JPEG2000 code-stream and takes into account the effect of channel errors at different quality layers in order to protect the coded bit-stream according to channel conditions using multi-rate low-density parity-check (LDPC) codes, leading to a flexib...

Absrract.-Log length exerted a critical influence in stabilizing large woody debris (LWD) pieces added as an experimental stream restoration technique. Logs longer than the average bank-full channel width (5.5 m) were significantly less likely to be displaced than logs shorter than this width. The longest log in stable log groups was significantly longer than the longest log in unstable groups....

In the 1930s, after only three years of scientific investigation at the University of Michigan Institute for Fisheries Research, cheap labor and government-sponsored conservation projects spearheaded by the Civilian Conservation Corps allowed the widespread adoption of in-stream structures throughout the United States. From the 1940s through the 1970s, designs of in-stream structures remained e...
