论行政法规之审查基准

审查基准是行政法规审查制度的重要组成部分,它不仅规定了行政法规合法性审查之宽严程度,也限定了审查机关之权限范围。根据我国宪法与立法法之规定,全国人民代表大会常务委员会对行政法规之审查以"合法性"为基准。这种"合法性"审查基准在行政法规制定权限审查、行政法规内容审查以及审查程序等方面遭遇现实难题,并因此净化了行政法规审查制度的现实效果,为此,有必要引借"合理性"审查基准,并借此推动我国行政法规审查制度的完善。     

一种适用于ARQ系统的码率兼容IRA码

提出用不规则重复累积(IRA)码构造码率兼容码。该码由删除法和扩展法两种方法构造。扩展法由高码率IRA码为母码,以RA码为扩展子码,克服了删除法在删除率较高时性能下降的缺点。仿真结果表明,RC-IRA码在HARQ系统中的吞吐率接近码率兼容turbo码,但译码复杂度远远低于Turbo码。     

同轴波导FEL放大器的非线性分析

以同轴波导、同轴混合磁铁摇摆器为模型,导出了自洽的注波三维非线性方程组,在考虑了电子初始速度零散效应、空间电荷波效应的影响及电子注在互作用区入口处的绝热压缩过程的基础上,编制了相应的计算软件。同时,通过数值分析的方法研究了自由电子激光器的饱和效率、频带宽度等高频特性和变参数摇摆器结构对延缓饱和、提高效率的作用。     

对虚假广告行为的规制

在我国,虚假广告已成公害,造成这种状况的原因之一是我国有关广告的现行立法存在缺陷。为有效遏止虚假广告行为,切实保护消费者的合法权益,维护市场主体的公平竞争,借鉴国外立法例,我国应明确界定虚假广告的法律概念,改革广告审查制度,加大对虚假广告行为的处罚力度,并注意立法的协调性和统一性。

Application of hybrid framework to facilitate lean six sigma implementation: a manufacturing company case experience

This study aims to propose a hybrid framework for lean six sigma (LSS) based on the prioritisation of barriers and solution approaches, to facilitate hassles free applications for handling the challenges of wastes reduction and quality improvement. The study identifies 27 LSS barriers and 22 solution approaches through literature review and utilises feedback from industry experts. For framework, study uses fuzzy AHP-PROMETHEE to prioritise LSS barriers and solution approaches. Incorporating fuzzy sets in analytical hierarchy process (AHP) ensures the optimality of barrier weights. Whereas, preference ranking organisation method for enrichment of evaluations (PROMETHEE) helps in pairwise comparisons of solution approaches with respect to each LSS barrier, facilitating fair judgements. This research guides regarding the development of framework and checks its suitability and robustness through case application of an Indian manufacturing organisation. Authors expect that researchers and practitioners will find study useful for LSS and multi criteria decision making(MCDM) domains.     

Analysis of quality-of-life adjusted failure time data in the presence of competing, possibly informative, censoring mechanisms

We derive estimators of the mean of a function of a quality-of-life adjusted failure time, in the presence of competing right censoring mechanisms. Our approach allows for the possibility that some or all of the competing censoring mechanisms are associated with the endpoint, even after adjustment for recorded prognostic factors, with the degree of residual association possibly different for distinct censoring processes. Our methods generalize from a single to many censoring processes and from ignorable to non-ignorable censoring processes.     

Reliability acceptance sampling plans for the Weibull distribution under accelerated Type-I censoring

Type-I censored reliability acceptance sampling plans (RASPs) are developed for the Weibull lifetime distribution with unknown shape and scale parameters such that the producer and consumer risks are satisfied. It is assumed that the life test is conducted at an accelerated condition for which the acceleration factor (AF) is known, and each item is continuously monitored for failure. Sensitivity analyses are also conducted to assess the effect of the uncertainty in the assumed AF on the actual producer and consumer risks, and a method is developed for constructing RASPs that can accommodate the uncertainty in AF.

水质预报系统的MPI+OpenMP并行优化研究

OpenMP(Open Multi-Processing)能够在共享存储环境中获得理想的并行性能,MPI＋OpenMP混合并行编程模型更贴近于多核心集群的体系结构。在多核心集群上进行实验,混合模型相对串行程序可缩短95%的运算时间,加速比超过20。实验结果表明,该混合模型比纯MPI并行的系统具有更优的加速比和扩展性,是对纯MPI并行系统的一种改进。
