Receiver-driven Layered Multicast

by Steven McCanne, Van Jacobson, Martin Vetterli , 1996
"... State of the art, real-time, rate-adaptive, multimedia applications adjust their transmission rate to match the available network capacity. Unfortunately, this source-based rate-adaptation performs poorly in a heterogeneous multicast environment because there is no single target rate — the conflicti ..."

in good throughput with transient short-term loss rates on the order of a few percent and long-term loss rates on the order of one percent. Finally, we discuss our implementation of a software-based Internet video codec and its integration with RLM.

Robust rate adaptation for 802.11 wireless networks

by Starsky H. Y. Wong, Hao Yang, Songwu Lu, Vaduvur Bharghavan - in ACM Mobicom , 2006
"... Rate adaptation is a mechanism unspecified by the 802.11 standards, yet critical to the system performance by exploiting the multi-rate capability at the physical layer. In this paper, we conduct a systematic and experimental study on rate adaptation over 802.11 wireless networks. Our main contribut ..."

must accurately estimate the channel condition despite the presence of various dynamics caused by fading, mobility and hidden terminals. Second, we design and implement a new Robust Rate Adaptation Algorithm (RRAA) that addresses the above challenge. RRAA uses short-term loss ratio to opportunistically

Analysis of Short-Term Energy Storage for Midsize Hydrostatic

by Rahul Dutta, Feng Wang, Bradley F. Bohlmann, Kim A. Stelson, Wind Turbine
"... This paper presents a novel method of capturing more energy from the wind using short-term energy storage in a hydrostatic wind turbine. A hydrostatic transmission (HST) not only provides reliable operation but also enables energy management features like energy regeneration using hydraulic accumula ..."

accumulators. In this study, turbulence-induced wind transients occurring near the rated power are exploited to extract more energy from the wind. Wind characteristics are analyzed to develop models to quantify the energy losses due to the wind turbulence and the potential energy gains from the short-term

Remembering over the short-term: The case against the standard model.

by James S Nairne - Annual Review of Psychology, , 2002
"... s Abstract Psychologists often assume that short-term storage is synonymous with activation, a mnemonic property that keeps information in an immediately accessible form. Permanent knowledge is activated, as a result of on-line cognitive processing, and an activity trace is established "in&quo ..."

Predicting Short-Term Currency Trends

by Frbny
"... Abstract Currency economists are puzzled by the relatively high frequency of massive, abrupt exchange-rate changes, such as dollar-yen's 11 percent decline on October 7, 1998. This paper provides evidence that such moves may be partly caused by stop-loss orders, which create rapid, self-reinfo ..."

Transient Behaviors of TCP-friendly Congestion Control Protocols

by Yang Richard Yang, et al. , 2001
"... We investigate the fairness, smoothness, responsiveness, and aggressiveness of TCP and three representative TCP-friendly congestion control protocols: GAIMD, TFRC, and TEAR. The properties are evaluated both analytically and via simulation by studying protocol responses to three network environment ..."

Under this scenario, we consider three types of sending rate variations: smoothness, short-term fairness, and long-term fairness. For a stationary environment, we observe that smoothness and fairness

High short-term bit-rates from TCP flows ∗

by Khushboo Shah, Stephan Bohacek
"... Micro-bursts from TCP flows are investigated. The chiprate is introduced and used to quantify the short-term bitrate of TCP flows. This paper examines packets with chiprates above the 90th percentile. The examination is performed over time scales ranging from 244 µs to 125 ms. Two issues are address ..."

SHORT-TERM CELL VOLUME REGULATION IN MYTILUS

by Californianus Gill, Arnold L. Silva, Stephen, H. Wright , 1994
"... Long-term acclimation of Mytilus californianus to 60 % artificial sea water (585 mosmol l21; ASW) led to a 30–40 % decrease in the taurine (53.5–36.9 mmol g21 wet mass) and betaine (44.8–26.2 mmol g21 wet mass) content of gill tissue, compared with that of control animals held in 100 % ASW (980 mosm ..."

, addition of valinomycin did not accelerate the rate of RVD observed in the absence of quinidine. These results indicate that long-term acclimation of Mytilus californianus gill in dilute sea water involves primarily losses of taurine and betaine, whereas short-term regulation of cell volume may involve

Short-Term Word-Learning Rate in Children With Normal Hearing and Children With Hearing Loss in Limited and Extended

These conditions represent typical listening environments for children with hearing loss (HL) and children with normal hearing (NH), respectively. Method: Thirty-six children with NH an ..."
