Objective To assess the prognostic significance of serum cardiac troponin I ( cTnI) concentration at the point of admission in patients with acute myocardial infarction. 目的探讨入院时血清心肌肌钙蛋白I(cTnI)水平对急性心肌梗死(AMI)预后的影响。
In this paper, the performance of integrating real-time and non real-time traffic in the PCF ( point coordination function) mode of IEEE 802.11 is studied, and a novel real-time traffic admission control algorithm is proposed. 研究了IEEE802.11PCF(pointcoordinationfunction)机制下集成实时业务和非实时业务的性能,提出了一种新的实时业务准入控制算法。
This dissertation, from a system design point of view, is devoted to the essential problems of RRM in CDMA systems based on SIC, such as power control, rate allocation, call admission control ( CAC) and system capacity analysis under multi-path diversity fading channels. 本文从系统设计出发,研究基于SIC的CDMA系统中的无线资源管理关键问题,包括功率控制、速率分配、呼叫接纳控制以及多径衰落分集信道下的容量分析等几个方面。
