Personality Organizations, Psychiatric Severity, and Self and Object Representations.

This study examined the hypothesis that psychotic, borderline, and neurotic personality organizations (POs) present a progressive differentiation between self and object representations and an increasing integration of their bad and good aspects. Fifty patients participated in the study. Measures included scales of self and object representations (S. J. Blatt, S. A. Bers, & C. E. Schaffer, 1993; S. J. Blatt, H. Wiseman, E. Prince-Gibson, & C. Gatt, 1991), as well as the Personality Organization Diagnostic Form (L. Diguer & L. Normandin, 1997) and estimations of psychiatric severity. Results showed that PO groups differed in terms of the integration of the object and its valence. It was also observed that although object and self representations were closely intertwined, the latter showed more discrimination between POs than the former. Psychiatric severity was shown to correlate more with object representations than self representations. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Capturing Attention When Attention "Blinks".

Four experiments addressed the question of whether attention may be captured when the visual system is in the midst of an attentional blink (AB). Participants identified 2 target letters embedded among distractor letters in a rapid serial visual presentation sequence. In some trials, a square frame was inserted between the targets; as the only geometric object in the sequence, it constituted a singleton. Capture effects obtained when the AB was most severe and when it was over were compared. There were 3 main results. First, capture occurred even when the AB was crippling, suggesting that a singleton exogenously engaged attention even when processing of a previous target was continuing apace. Second, when the singleton contained the key target feature, capture effects were clearly manifest. Third, even when the singleton did not possess the key target feature, it still succeeded in capturing attention, although the effects were both feeble and fleeting.

Defects tracking matrix for mass customization production based on house of quality

The vision of mass customization has driven a movement toward low volume, high variety mass customization production (MCP) at low price. However, defect identification and defect tracking in such systems are extremely difficult because of the frequent reconfiguration needed by the number of different part types and the interruption of the information flow about quality with each reconfiguration of the system. It is important to quickly rebuild quality information flow with MCP system’s reconfiguration synchronously. This paper introduces a defect tracking method based on Quality Function Deployment for every MCP system module. A defects tracking matrix (DTM) based on the House of Quality directly connects manufacturing technologies with quality defects inside a MCP module. Each MCP reconfiguration requires the DTMs’ rearrangement and DTM-chain is proposed. A dynamic reconstructing algorithm synchronizes the DTM-chain with each MCP reconfiguration. A case study demonstrates the usefulness of the DTM and DTM-chain.

基于相关性反馈的自适应热点话题追踪模型

针对在热点话题追踪过程中容易发生话题漂移的问题,提出了基于相关性反馈的自适应热点话题追踪模型。为准确把握话题的动态演变过程,首先,在词频-逆向文档频率(term frequency-inverse document frequency, TF-IDF)的基础上引入了相关度因子。其次,构造了报道与话题的相关度计算公式和新特征词能否反馈加入到话题词汇库的判别函数。同时,利用了话题词汇库本身的特性,构造了自适应更新阈值和自适应相关阈值的动态计算方法。最后,根据各个特征词对该话题贡献度的大小,对更新后的词汇库中的各特征词动态赋予新权重。实验结果显示,和其它3类追踪器相比,该追踪器模型的漏报率平均降低0.018、误报率平均降低0.063,这表明,该追踪模型更适合于解决话题漂移问题。

核燃料组件导向翼损伤回堆复用的分析

2011年1月,中核核电运行管理有限公司二厂（简称二厂）换料大修,外观检查发现燃料组件A导向翼脱落。经国家核安全局（NNSA）审评批准后,将燃料组件A装入堆芯规定位置。2012年3月再次换料大修,将燃料组件A御出堆芯。经检查确认燃料组件A完整,无异常变化。此次实践为此类型的导向翼损伤,燃料组件回堆复用提供参考,为同类型燃料组件导向翼损伤后回堆复用的标准制定提供案例支持。
