基于HoR的可靠性配置方法研究

运用HoR(House of Reliability)思想,将故障树分析(FTA)、失效模式影响及危害性分析(FMECA)整合于质量功能配置(QFD)中,建立可靠性配置流程:对系统可靠性指标进行分配,解决了传统方法过度依赖于主观打分的问题;在此基础上,建立以顾客可靠性满意度最大和配置成本最低为目标的模型,将可靠性指标配置到具体的工程技术特征上。并以数控车床电主轴为例,对模型的有效性进行了验证。     

Type D personality and the development of PTSD symptoms: A prospective study.

Psychological trauma and prolonged stress may cause mental disorders such as posttraumatic stress disorder (PTSD). Pretrauma personality is an important determinant of posttraumatic adjustment. Specifically, trait neuroticism has been identified as a risk factor for PTSD. Additionally, the combination of high negative affectivity or neuroticism with marked social inhibition or introversion, also called Type D personality (Denollet, 2000), may compose a risk factor for PTSD. There is no research available that examined pretrauma Type D personality in relation to PTSD. The present study examined the predictive validity of the Type D personality construct in a sample of Dutch soldiers. Data were collected prior to and 6 months after military deployment to Afghanistan. Separate multiple regression analyses were performed to examine the predictive validity of Type D personality. First, Type D personality was defined as the interaction between negative affect and social inhibition (Na × Si). In a second analysis, Type D was defined following cutoff criteria recommended by Denollet (2000). Results showed that negative affectivity was a significant predictor of PTSD symptoms. Social inhibition and the interaction Na × Si did not add to the amount of explained variance in postdeployment PTSD scores over the effects of childhood abuse, negative affectivity, and prior psychological symptoms. A second analysis showed that Type D personality (dichotomous) did not add to the amount of explained variance in postdeployment PTSD scores over the effects of childhood abuse, and prior psychological symptoms. Therefore, Type D personality appears to be of limited value to explain development of combat-related PTSD symptoms. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Circumventing mental health stigma by embracing the warrior culture: Lessons learned from the Defender's Edge program.

Despite considerable efforts on the part of the Department of Defense, Department of Veterans Affairs, and the wider mental health community, mental health stigma continues to be a significant barrier to seeking help by service members, highlighting the need for newer modes of thought. A significant factor contributing to this stigma is the fundamental difference between traditional mental health approaches and the warrior culture. As a mental health prevention initiative, the Defender's Edge (DEFED) program was specifically developed to fit within the United States Air Force Security Forces (SF) charged with ground combat operations while deployed to Iraq. DEFED adopted a strengths-based philosophy and integrated a psychologist into the SF culture. Evaluative feedback from 192 program participants is presented, demonstrating high programmatic acceptability and feasibility suggestive of success in circumventing mental health stigma.

不均匀布置传感器网络定位优化算法

目前许多针对传感器网络的定位算法仅适用于节点分布比较均匀的网络,在不均匀网 络中应用时定位精度较低。而在实际应用中,由于监测区域地形或应用需求等因素的限制,网络中 节点的分布往往是不均匀的。引入虚拟空洞以实现节点间的距离优化,并结合多维定标技术,提出 一种可应用于不均匀布置网络的定位算法(MDS-DO). 在半C 型节点布置区域内,对该算法的节 点定位效果进行了仿真分析。结果表明,在不同节点数量及连通度的情况下,MDS-DO 算法都能取 得较好的定位效果。而且在连通度较高的条件下,MDS-DO 算法的平均定位误差比经典的MDS- MAP 算法降低了约90%.
