In this contribution, we present an analysis of the effect of changing RM cell intervals on ABR performance. We describe our newly developed ABR model in OPNET. This OPNET ATM model contains enhanced features to support the QoS capabalities of ATM, and a comprehensive ABR feedback model. We describe the various features of the ATM model, and use it for our simulation and analysis.

The auditory-brainstem response (ABR) to short and simple acoustical signals is an important clinical tool used to diagnose the integrity of the brainstem. The ABR is also employed to investigate the auditory brainstem in a multitude of tasks related to hearing, such as processing speech or selectively focusing on one speaker in a noisy environment. Such research measures the response of the br...

The auditory brainstem response (ABR) is a test widely used to assess the integrity of the brain stem. Although it is considered to be an auditory-evoked potential that is influenced by the physical characteristics of the stimulus, such as rate, polarity and type of stimulus, it may also be influenced by the change in several parameters. The use of anesthetics may adversely influence the value ...

The volume of video traffic is continuing to grow rapidly over cable networks. While a majority of IP video on DOCSIS networks today is over-the-top video from third parties, operators are increasing the amount of programming their subscribers can access on IP video-capable devices. Additionally many operators are pursuing IP video deployments that are at various stages from planning, testing, ...

The cost eeective ABR service is suitable for transmitting bursty compressed video over ATM network. Here, we propose a Fast Buuer Fillup (FBF) scheme to run VoD over ATM network with ABR service. We develop models to determine buuer size at the client and the server for our scheme. We also develop relationships between the startup delay, the ABR service parameters, and the network congestion s...

OBJECTIVE To use the over-complete discrete wavelet transform (OCDWT) to further examine the dual structure of auditory brainstem response (ABR) in the dog. METHODS ABR waveforms recorded from 20 adult dogs at supra-threshold (90 and 70dBnHL) and threshold (0-15dBSL) levels were decomposed using a six level OCDWT and reconstructed at individual scales (frequency ranges) A6 (0-391Hz), D6 (391-...

Due to its structure, hexamethylenetetramine (HMT) is a slowly biodegradable substance, hydrolysing in acid environment to ammonium and formaldehyde. Formaldehyde is toxic under normal conditions for biological treatment processes. Following an adaptation, a formaldehyde concentration of 1000 mg·l may become biodegradable both in aerobic and anaerobic conditions. Acidic conditions for hydrolysi...

In this study, the problem of multiplexing VBR and ABR traac is considered. VBR is uncontrollable, while ABR is provided the remaining service capacity in a controllable fashion. While in a given state, the VBR source is supposed to transmit at a xed rate; the VBR time scale is then deened in terms of the time constant associated with the rate of change of the rate of the VBR source. ABR source...

| EEcient support for scalable multipoint-to-multipoint (mpt-mpt) communication in ATM has recently become a hot topic of discussion at the ATM Forum. In our previous study 11], we presented a new class of eecient switch algorithms for point-to-multipoint (pt-mpt) ABR service that deliver high performance in terms of fairness and link utilization and are signiicantly simpler to implement than o...

The auditory brainstem response (ABR) to clicks is widely used for early detection of hearing loss in the child at risk for hearing dysfunction, but there is a lack of direct, large-sample estimates of test accuracy. In this report, results and preliminary analyses are presented that relate click ABR thresholds obtained at 3 to 12 months corrected age to detailed follow-up behavioral puretone a...
