软件质量保证中不符合问题的探讨与系统实现

软件质量保证过程主要有审计、评审和处理不符合问题等三项主要活动,其中处理不符合问题是软件质量保证的核心.本文明确了多角色参与处理不符合问题的流程,通过对流程的系统分析,在J2EE的B/S应用架构下,以Struts作为表现层框架、Hibernate作为数据持久层框架,设计实现了一个软件质量审计系统的不符合问题处理部分,并利用了XML和JavaMail等技术.该系统职责明确、通过邮件操作提高工作效率,具有良好的可扩展性、实用性和可维护性.     

开放网络中基于担保的主观信任模型

针对目前存在的主观信任模型不能很好地解决信任初始值的设定和实体匿名问题,利用主观逻辑理论对实体的信任关系进行建模,提出了一种开放网络中的新型主观信任模型,定义了担保信任和全局信誉,依靠实体之间的担保关系设定信任初始值,给出了推荐信任和担保信任的搜索算法。模型有效地描述了实体间主观信任关系,保证了实体的匿名性和信任消息的完整性,从而防止了针对欺骗和联合欺骗。通过仿真实验证明了模型的有效性。

A qualification procedure to manufacture and repair aerospace parts with electron beam melting

This paper is focused on qualification procedures for metal parts manufactured using new additive manufacturing (AM) techniques in the aerospace industry. The main aim is to understand the interaction between these technologies and the stringent regulatory framework of this industry in order to develop correct quality assurance and quality control procedures in accordance with the certification process for the technology and spare parts. These include all the testing and validation necessary to implement them, as well as to maintain their capability throughout their life-cycle, specific procedures to manufacture or repair parts, work-flows and records, amongst others. An entire qualification procedure for electron beam melting (EBM) to reproduce and repair an aerospace part has been developed and it is presented in this paper. These will be part of the future quality assurance and quality management systems of those aerospace companies that implement AM in their supply chain.     

Utility accrual real-time scheduling for multiprocessor embedded systems

We present the first Utility Accrual (or UA) real-time scheduling algorithm for multiprocessors, called the global Multiprocessor Utility Accrual scheduling algorithm (or gMUA). The algorithm considers an application model where real-time activities are subject to time/utility function time constraints, variable execution time demands, and resource overloads where the total activity utilization demand exceeds the total capacity of all processors. We consider the scheduling objective of (1) probabilistically satisfying lower bounds on each activity’s maximum utility, and (2) maximizing the system-wide, total accrued utility. We establish several properties of gMUA including optimal total utility (for a special case), conditions under which individual activity utility lower bounds are satisfied, a lower bound on system-wide total accrued utility, and bounded sensitivity for assurances to variations in execution time demand estimates. Finally, our simulation experiments validate our analytical results and confirm the algorithm’s effectiveness.

Partitioning for selective assembly

Selective assembly is a means by which high-precision assemblies may be fabricated from relatively low precision components. This is accomplished by partitioning the component populations into groups prior to random assembly. This paper details an enhanced BASIC program that will generate group partitions given component distributions and the desired number of groups.     

Fiber Optic Bend Sensor for In-Process Monitoring of Polymeric Composites

Wrinkles, porosity, delaminations and other defects introduced during the manufacturing processing can compromise mechanical performance of advanced composites. This paper describes a method of using fiber optic sensors for monitoring the formation of graphite fiber bending in real time during manufacturing process. Theoretical formulation of the sensor behavior and experimental results are presented. The response of the sensor to composite fiber bending is characterized. The application to analyzing the formation of wrinkles in compression molding of graphite/epoxy composites is demonstrated.
