Coping with Short-term Sustained Peak Demands ,several cost-effective strategies

For most open universities, in fact for most universities, there will arise occasions when some online activities will have to be completed by all students in a very short time interval. These occasions usually result in a great rush to get online as quickly as possible ; the rush is often made worst by the limited good choices on offer such that usually only the earliest can get the best. Choosing and confirming elective subjects, when only a limited number for each are offered, on a first-come-first-served basis is an example. At the Open University Malaysia the rush occurs when confirming offered subjects and choosing face-to-face meeting timetable. Most students rushed to be earliest to ensure choice slots in the timetable are obtained. Available I. T. resources such as Internet bandwidth and servers cannot cope with these short-term sustained peak demands. Unless these peak demands are met, however, online services will slow down drastically resulting in long queues of users waiting to be served. Providing excess capacity, if at all possible, to ensure these short duration peak demands can be met would not be cost-effective since most of the time these resources are not utilised. This paper will look at some cost-effective approaches to meeting these short-term peak demands.

武都力治疗盐敏感性高血压性价比的评定

目的:探寻治疗盐敏感性高血压最优性价比的治疗方案。方法:将急性盐水负荷试验筛选出的48例盐敏感性高血压患者随机分为实验组与对照组,实验组服用武都力治疗,对照组采用硝苯地平缓释片加依苏片治疗,治疗8周前后各行ABPM及实验室检查一次,并比较两组治疗方案每天平均药品费用。结果:ABPM显示两组8周末24 h、日间、夜间收缩压/舒张压(SPB/DBP)较治疗前分别下降:实验组(9.2±4.8/5.8±4.2)mmHg、(10.4±6.2/6.6±3.0)mmHg、(6.7±8.7/5.0±7.4)mmHg;对照组(9.4±5.4/6.2±4.1)mmHg、(10.6±6.2/6.7±4.1)mmHg、(6.8±9.1/5.0±7.7)mmHg。两组均无严重不良反应。实验组日均药费0.725元,对照组日均药费3.513元。结论:武都力是治疗盐敏感性高血压性价比较高的药物。
