The current best-effort Internet does not guarantee the bandwidth availability between a receiver and a sender, and so renders any quality-of-service (QoS) control difficult, if not impossible. This paper proposes a novel predictive buffering algorithm for streaming video not from one, but from multiple senders to a receiver over the best-effort Internet. In particular, the predictive buffering...

In this paper, we propose an approach to provide a significantly scalable video-on-demand service mainly designed for multicast environments where users are geographically close to each other and may have access to the same video feature at nearly the same time. Distance learning is a suitable candidate for this approach. The basic idea behind our proposed approach is to advantage of appropriat...

Increased calcium buffering in basal forebrain neurons during aging. J. Neurophysiol. 80: 350-364, 1998. Alterations of neuronal calcium (Ca2+) homeostasis are thought to underlie many age-related changes in the nervous system. Basal forebrain neurons are susceptible to changes associated with aging and to related dysfunctions such as Alzheimer's disease. It recently was shown that neurons from...

Modern switches and routers often use dynamic RAM (DRAM) in order to provide large buffer storage space. However, the effective bandwidth of DRAM is frequently a limiting factor in the design of high-speed switches and routers. The focus of this paper is to introduce a packet-buffering architecture called the parallel packet buffering (PPB), which increases the effective memory bandwidth signif...

one of the most important items for better file system performance is efficient buffering of disk blocks in main memory. efficient buffering helps to reduce the widespeed gap between main memory and hard disks. in this buffering system, the block replacement policy is one of the most important design decisions that determines which disk block should be replaced when the buffer is full. to overc...

Differences in synaptic transmission between rod and cone photoreceptors contribute to different response kinetics in rod- versus cone-dominated visual pathways. We examined Ca(2+) dynamics in synaptic terminals of tiger salamander photoreceptors under conditions that mimicked endogenous buffering to determine the influence on kinetically and mechanistically distinct components of synaptic tran...
