PURPOSE Accommodative amplitude in persons with diabetes was investigated using data collected as part of the Early Treatment Diabetic Retinopathy Study. METHODS Accommodative amplitude was measured at the baseline visit in 1,058 patients who had good visual acuity and who were less than 46 years old. Risk factors for low accommodative amplitude at(More)
The purpose of this study was to characterize the clinical course of myopia in a selected pediatric population. The computerized records of a health maintenance organization provided longitudinal data on 501 children aged 5 to 15 years. We examined the influence of age at diagnosis, gender, race, and initial refraction on progression of myopia. Mean(More)
When designing and configuring an ATM-based B-ISDN, it remains difficult to guarantee the Quality of Service (QoS) for different service classes, while still allowing enough statistical sharing of bandwidth so that the network is efficiently utilized. These two goals are often conflicting. Guaranteeing QoS requires traffic isolation, as well as allocation(More)
Most algorithms proposed for controlling traffic prior to entering ATM networks are based on static mechanisms. Such static control mechanisms do not account for the dynamics of the user traffic or the network state. Some dynamic control algorithms have been proposed, but most of these algorithms are extremely complex and may make it difficult to provide(More)
The effects of an automated system on team processes and performance were assessed in a laboratory simulation. Two-person crews were required to fly a complex emergency-response scenario under conditions of low and high workload. These flights were completed with or without the aid of an autopilot. The results indicated that the autopilot was effective in(More)
This paper describes a simulation study comparing delay and throughput performance of several access/backbone combinations of Frame Relay, Asynchronous Transfer Mode (ATM), and IEEE 802.6 broadband networking technologies. The comparisons are made using similar Metropolitan Area Network (MAN) configurations supporting integrated traffic from voice, video,(More)
