In this paper we consider ABR traffic which shares an output port of a switch with delay sensitive CBR/VBR traffic. Congestion control of the ABR traflic is achieved by mean? of an Explicit Rate control scheme. Two important performance measurea are evaluated using an analytical model : the ABR-buffer occupancy distribution in the switch and the ABR traffic throughput. We consider two types of ...

We develop a simulation model for the ATM ABR service, and use it to engineer ABR congestion control behavior. Although significant work has been performed on ABR rate allocation algorithms at network switches, little work has focused on the end system behavior, which we examine in this paper. The effect of the speed of links on the path from the source to the destination, and the connection ro...

The bone-conduction (BC) tone ABR has been used clinically for over 20 years. The current study formally evaluated the test performance of the BC tone-evoked ABR in infants with hearing loss. Method. By comparing BC-ABR results to follow-up behavioural results, this study addressed two questions: (i) whether the BC tone ABR was successful in differentiating children with conductive versus senso...

Auditory brain-stem response (ABR) was measured in 40 patients (80 ears) with confirmed hydrocephalus. Eighty-eight percent of these patients showed some form of ABR abnormality. Responses indicative of brain-stem dysfunction consisted of prolonged I-V interwave latency (38%), reduced V/I amplitude ratio (33%), and abnormalities in wave-shape of components III (27%) and V (53%). In addition, 70...

The rate control mechanism for Available Bit Rate ABR tra c as de ned by the ATM Forum does not distinguish between di erent types of ABR connections However since ABR tra c may result from a heterogeneous set of applications there is an apparent need for a ow control scheme that can distinguish between and give di erential treatment to di erent classes of ABR connections In this study a multi ...

The Available Bit Rate (ABR) service has been shown to enable persistent, greedy data sources to e ciently utilize ATM network resources. However, the throughput for bursty TCP over ABR data tra c in the presence of interfering tra c may not be as good as for persistent ABR sources without interfering tra c. This paper shows that in a comparison of rate based ABR schemes (EPRCA and ERICA) and a...

BACKGROUND Recent studies have shown effective clinical results after arthroscopic Bankart repair (ABR) but have shown several risk factors for re-dislocation after surgery. We evaluated whether patients are at a risk for re-dislocation during the first year after ABR, examined the recurrence rate after ABR, and sought to identify new risk factors. METHODS We performed ABR using bioabsorbable...

In mice, the auditory brainstem response (ABR) is frequently used to assess hearing status in transgenic hearing models. The diagnostic value of the ABR depends on knowledge about the anatomical sources of its characteristic waves. Here, we studied the contribution of the inferior colliculus (IC) to the click-evoked scalp ABR in mice. We demonstrate a non-invasive correlate of the IC response t...

Previous studies have demonstrated an increase in the arterial baroreflex (ABR) control of muscle sympathetic nerve activity (MSNA) during isolated activation of the muscle metaboreflex with postexercise muscle ischemia (PEMI). However, the increased ABR-MSNA control does not appear to manifest in an enhancement in the ABR control of arterial blood pressure (BP), suggesting alterations in the t...

In this paper we evaluate various aspects of the ABR flow control schemes using three different evaluation techniques: analysis, simulation and experiments. A discrete-time Markov model alows the evaluation of the influence of different system parameters (distance between source and switch, burstiness of CBR/VBR traffic, time in between computation of Allowed Cell Rate and burstiness of ABR tra...
