AbstractThis note is an attempt to trace the change and continuity of leftist political policies, and to analyse why the Left generally, especially the Malay Left, has not been successful in Malaysian politics. It questions why the Malaysian Left was stafter the Second World War but slowly dissipated until it is almost crippled now. Other than examining the formation and the roles of the Malaysian Left and their struggles for independence, this note also sorts out the factors of the unsuccessful struggles to get wide Malay support for the Malay-dominated Malay Nationalist Party of Malaya (PKMM) and the Chinese-dominated Communist Party of Malaya (CPM). 相似文献

本文在衰落信道下将级联网格编码调制（ＴＣＭ）和连续相位调制（ＣＰＭ）应用于直接序列扩频多址（ＤＳ／ＳＳＭＡ）系统中．作者分别采用了理论分析和数值模拟两种方法研究了级联ＴＣＭ／ＣＰＭＤＳ／ＳＳＭＡ系统的性能，结果表明在相同的条件下采用级联ＴＣＭ／ＣＰＭ编码调制方式的ＤＳ／ＳＳＭＡ系统的错误概率远小于采用单一ＴＣＭ或ＣＰＭ的ＤＳ／ＳＳＭＡ系统的错误概率． 相似文献

Using Communication Privacy Management (CPM), this study analyzed Emergency Healthcare Providers (EHP; i.e., Emergency Room Nurses, Paramedics, Emergency Medical Technicians, etc.) frequent experience of witnessing death, the dying processes, and regular involvement at the end-of-life. Twenty interviews from across the United States offered accounts of witnessing the death of a patient, communicating with the patient’s families, coworkers, and personal networks. The first research question explored the population’s normalization of death and changed outlook of dying. This population sees death and dying in real-time and must disconnect at the moment from their emotions to do their jobs. The second research question focused on preparing patient families for death, coping with coworkers, and protecting personal networks. In communicating with patient families, EHP educates/answers questions, advocate for families to be present during life-saving procedures and offer verbal and nonverbal comfort. In talking with coworkers, EHP copes with reassuring skill competency and offering emotional social support. Lastly, in communicating with their networks, EHP struggle with discussing emotions and event details in a protective function. From these results, the benefits, and challenges of communicating about death regularly are offered through a CPM lens, and recommendations to help the general population deal with death are given. 相似文献

The critical path method/program evaluation and review technique method of project scheduling is based on the importance of managing a project's critical path(s). Although a critical path is the longest path through a network, its location in large projects is facilitated by the computation of activity slack. However, logical fallacies in oft‐repeated statements of the relationship between slack and the critical path make it easy to overlook the phenomenon of zero‐slack, noncritical paths. This article points out the fallacies and then describes and illustrates the phenomenon. We conclude with teaching recommendations to avoid suboptimal decisions in reducing project duration. 相似文献

目的:探讨全膝关节置换术后早期规范的运用渐进式肌力康复训练配合持续被动训练机(CPM)的康复护理效果。方法:将78例患者随机分为治疗组(A组)、对照组(B组)各39例,术前、术后两组患者给予相同康复护理,并采用膝关节HSS各项评分,A组行渐进式肌力康复训练配合CMP锻炼;B组行渐进式肌力康复训练,观察两组术后康复效果。结果:A、B两组患者术前膝关节HSS各项评分均无明显差异(P0.05);术后膝关节HSS各项评分较术前明显差异(P0.05),但术后膝关节肌肉组织肌力、膝关节稳定性与B组的患者比较差异无统计学意义(P0.05)。结论:术后早期规范的渐进式肌力康复训练配合CPM可改善膝关节疼痛、功能、活动度、屈曲程度,有利于减少早期全膝关节置换术后的并发症,可进一步临床推广应用。 相似文献

This paper presents an equalization algorithm for continuous phase modulation (CPM) over frequency-selective channels. A specific training sequence is first embedded in each data packet. By recursive least-squares (RLS) estimation, the channel information parameters can be acquired, and a fractionally spaced equalizer performs joint decoding and equalization. Simulation results show that the proposed algorithm can acquire the channel information parameters rapidly and accurately, and that the fractionally spaced equalizer can eliminate the intersymbol interference (ISI) effectively, and is not sensitive to timing inaccuracy, so this algorithm can be exploited for demodulation system in burst mode. 相似文献
