基于变权物元可拓模型的二次设备状态综合评价

针对二次设备状态评价的特点,提出了基于变权物元可拓的二次设备状态综合评价模型。结合物元可拓理论,确立二次设备的状态信息经典域,建立状态参量物元矩阵。同时,充分考虑权重确定过程的主观性,运用变权理论对各评价指标的权重进行修正,并比较了三种权重确定方法。结果表明,变权法对异常指标具有放大作用,更加符合设备管理要求。最后引入贴近度函数对二次设备的状态进行综合评判。以某220 kV变电站某二次装置为例,评价结果显示设备处于注意状态,偏向异常状态的程度较大,结果基本符合设备实际运行情况,从而验证了该方法的正确性。     

A probabilistic self-validating soft-sensor with application to wastewater treatment

In the wastewater treatment plants (WWTPs), soft sensors are viewed as a simple signal estimator for hard-to-measure quantities. However, the presence of unreliable data, coupled with increasing demands for measurement quality assurance, has rendered inadequate such a simplistic view. In this paper, a probabilistic self-validating soft-sensor is proposed with the capability of performing self-diagnostics, self-reconstruction and online uncertainty measurement. In this framework, data collecting for soft-sensor modeling (easy-to-measure data) is validated by a Variational Bayesian Principal Component Analysis (VBPCA) model before performing a soft-sensor model construction. By integrating Relevant Vector Machine (RVM) as a predictive model, not only prediction values are obtained, but also the credibility of information for easy-to-measure and hard-to-measure quantities can be generated. The performance of the proposed soft-sensor is validated through two simulation studies of WWTPs with different process characteristics. The results suggest that the proposed strategy significantly improves the prediction performance.     

Dude,where’s my avacar? A mixed-method examination of communication in the driving context

Drivers who feel social closeness with other drivers tend to drive more safely, according to previous research. Given this, we examine how communication in the driving context influences social closeness, drawing from theories of computer-mediated communication, a context with notable similarities to the road. A survey study found that social closeness with others is associated with greater communication comfort and identity expression through the car, but less treatment of the car as a social entity. An interview study provides context and caveats for these generalizations. Together, these studies present implications for near-future social-mobility services relating to safety on the road.     

Adaptive synchronization of fractional‐order complex networks via pinning control

Adaptive synchronization of a class of fractional‐order complex networks is investigated in this paper. On the basis of the fractional‐order system stability theory, adaptive synchronization criteria of fractional‐order complex networks with 0 < q < 1 is achieved. Furthermore, pinning control method is then suggested to control the networks, and adaptive strategy is employed to tune the control gains and coupling strength. Because the nodes with high degree may not be the center of the networks, a new attempt to choose the pinned nodes on the basis of the closeness centrality scheme is proposed. Finally, numerical simulations are given to verify the effectiveness of the proposed approach based on the closeness centrality scheme. Copyright © 2012 John Wiley & Sons, Ltd.

Marital closeness, functional disability, and adjustment in late life.

Socioemotional selectivity theory (SST) posits that emotionally close relationships are increasingly valued as people perceive constraints on time. Based on SST, this study of 1,532 older married persons hypothesized that emotional dimensions of marriage would more strongly predict adjustment at higher levels of functional disability. High levels of marital closeness were negatively associated with depression and anxiety and positively associated with self-esteem. Consistent with predictions derived from SST, marital closeness moderated the negative psychological effects of high levels of functional disability on depression, anxiety, and self-esteem. Results are discussed in the context of SST and traditional stress-buffering models of social support. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Effects of mindset on the predictive validity of relationship constructs.

The authors investigated the effects of deliberative versus implemental mindsets on the predictive validity of relationship constructs. Dating students anticipating the transition from university to work deliberated about increasing their commitment or thought about how to maintain their relationships after graduation. As hypothesized, this mindset manipulation interacted with subsequent ratings of relationship closeness and perceived partner commitment to predict relationship status six months later. Ratings made by those in a deliberative mindset were more strongly associated with relationship survival than were similar ratings made by those in an implemental mindset. Deliberatives' relationship appraisals were only positive if their relationships were on a successful trajectory whereas implementals' relationship appraisals were positive whether their relationships were on course for success or dissolution.
