A study of the 'appropriateness' of 267 consecutive emergency admissions to a district paediatric department showed that admission was at a peak in the evening and night time. Breathing difficulty, head injury, and fever were the commonest presenting problems. Sixty three per cent of admissions occurred between 6 pm and 8 am and these were more likely to be after self referral to the accident a...

Many audio and video \play-back" applications require that all of their packets arrive within their play-back time. Furthermore, the applications with the hard real-time requirements also require guaranteed service from the network. These applications are covered under the \Guaranteed Quality of Service" speciications by the IETF. It guarantees that the packets will arrive within the guaranteed...

Provisioning multiple service classes with different performance characteristics (e.g., throughput and delay) is an important challenge for future packet networks. However, in large-scale networks, individually managing each traffic flow on each of its traversed routers has fundamental scalability limitations, in both the control plane’s requirements for signaling, state management, and admissi...

Network admission control (NAC) limits the traffic in a network to avoid overload and to assure thereby the quality of service (QoS) for admitted flows. Overload may occur due to exceptional traffic demand, but it is mostly caused by redirected traffic due to link failures. Conventional NAC methods cannot cope with network outages and fail when they are needed most. This paper categorizes exist...

We present algorithms and hardness results for three resource allocation problems. The first is an abstract admission control problem where the system receives a series of requests and wants to satisfy as many as possible, but has bounded resources. This occurs, for example, when allocating network bandwidth to incoming calls so the calls receive guaranteed quality of service. Algorithms can ha...

This study describes criteria used by graduate nurse anesthesia educational programs (GNAEPs) in selecting students for admission. The investigators prepared and distributed a 15-item questionnaire to 71 GNAEPs as listed by the Council on Accreditation of Nurse Anesthesia Eduational Programs for December 1992. Thirty-eight of 71 (54%) of GNAEPs participated in this study. Upon examination of st...

Admission control (call control) is a well-studied online problem. We are given a xed graph with edge capacities, and must process a sequence of calls that arrive over time, accepting some and rejecting others in order to stay within capacity limitations of the network. In the standard theoretical formulation, this problem is analyzed as a beneet problem: the goal is to devise an online algorit...

abstract background: risk for anxiety and depression is increased in women with high‑risk pregnancy. the aim of this study was to evaluate anxiety and depression in women with mild and severe preeclampsia at admission and 6 weeks postpartum. materials and methods: in this cohort study, 122 preeclamptic women who were admitted to the public hospital and tamin ejtemaee hospital of mashhad were in...
