AbsnaciIn this paper, we analyzed the performance of dynamic resource allocation with channel de-allocation and buffering in cellular networks. Buffers are applied for data traffic to reduce the packet loss probability while channel de-allocation is exploited to reduce the voice blocking probability. The results show that while buffering data traffic can reduce the packet loss probability, it h...

FAST TCP has been shown to be promising in terms of system stability, throughput and fairness. However, it requires buffering which increases linearly with the number of flows bottlenecked at a link. This paper proposes a new TCP algorithm that extends FAST TCP to achieve (α, n)-proportional fairness in steady state, yielding buffer requirements which grow only as the nth power of the number of...

Epistatic interactions, manifested in the effects of mutations on the phenotypes caused by other mutations, may help uncover the functional organization of complex biological networks1–3. Here, we studied system-level epistatic interactions by computing growth phenotypes of all single and double knockouts of 890 metabolic genes in Saccharomyces cerevisiae, using the framework of flux balance an...

This study was to evaluate the acid-buffering capacity and antibacterial properties of orthodontic adhesives containing bioactive glasses (BAGs) (45S5, 45S5F, S53P4), Hydroxyapatite, beta-tricalcium phosphate, Canasite. Fillers comprising 15 wt% glasses, HAp, β-TCP, Canasite incorporated with 55 silanated glass were added a mixture UDMA/TEGDMA. Acid-buffering tested by exposing disc-shaped samp...

by GRAHAM W. ALLDREDGE The networked environment presents many new challenges for the design of feedback control systems. Though networked control systems (NCSs) are subject to the performance-degrading effects of both discretization and time-varying, random delay, traditional control algorithms may still suffice depending on the plant, network, and performance criteria. This thesis investigate...

This study was carried out to identify the suitable buffer for cryopreservation of buffalo semen. Semen was collected with artificial vagina (42 degrees C) from four buffalo bulls. Split pooled ejaculates (n=5), possessing more than 60% visual sperm motility, were extended at 37 degrees C either in tri-sodium citrate (CITRATE), Tris-citric acid (TCA), Tris-Tes (TEST) or Tris-Hepes (HEPEST). Sem...

Recently, P2P streaming techniques have been a promising solution to a large-scale live streaming system because of their high scalability and low installation cost. In P2P live streaming systems, however, it is difficult to manage peers’ buffers effectively, because they can buffer only a limited amount of data around a live broadcasting time in the main memory and suffer from long playback la...
