基于不确定非线性智能电网感知网络控制系统方法研究

针对传统的不确定时滞的鲁棒控制系统不能满足现代电力系统发展的需求,提出一种基于不确定非线性智能电网感知云网络化控制识别方法。使用传统的数据值和基于电力网络到网络系统模型作为电力感知网络到网络模型的电力云网络,控制数据优化使用电源感知网络,而不是利用控制节点的预测值,突破了鲁棒控制的不确定时滞系统的控制效果。运用感知模型中的正向云算法修正加权系数,仿真实验证明,该识别方法能够很好地优化传统的不确定时滞鲁棒控制电力系统,具有良好的适应性和鲁棒控制性,进一步提高了智能电网传感云网络控制的各项性能指标。     

高原地区不同品牌混合动力公交车适应性分析

针对昆明示范运营的混合动力公交客车,依托昆明市新能源汽车示范运行信息化管理与监控平台,采集同一公交线路上不同品牌混合动力公交客车运行数据,并对运行车辆的油耗数据和故障进行对比分析。结果表明:三种不同品牌混合动力公交客车节油效果比纯柴油公交客车明显;高原环境的差异性和技术条件的不成熟导致混合动力公交客车故障率明显高于纯柴油公交客车;不同品牌混合动力公交客车在该公交线路上的性能存在较大差异。     

Contingent Leadership and Effectiveness of Trauma Resuscitation Teams.

This research investigated leadership and effectiveness of teams operating in a high-velocity environment, specifically trauma resuscitation teams. On the basis of the literature and their own ethnographic work, the authors proposed and tested a contingency model in which the influence of leadership on team effectiveness during trauma resuscitation differs according to the situation. Results indicated that empowering leadership was more effective when trauma severity was low and when team experience was high. Directive leadership was more effective when trauma severity was high or when the team was inexperienced. Findings also suggested that an empowering leader provided more learning opportunities than did a directive leader. The major contribution of this article is the linkage of leadership to team effectiveness, as moderated by relatively specific situational contingencies.

To Empower or Not to Empower Your Sales Force? An Empirical Examination of the Influence of Leadership Empowerment Behavior on Customer Satisfaction and Performance.

This research focuses on the impact of leadership empowerment behavior (LEB) on customer service satisfaction and sales performance, as mediated by salespeople's self-efficacy and adaptability. Moreover, the authors propose an interactive relationship whereby LEB will be differentially effective as a function of employees' empowerment readiness. The authors' hypotheses are tested using survey data from a sample of 231 salespeople in the pharmaceutical field, along with external ratings of satisfaction from 864 customers and archival sales performance information. Results indicated that contrary to popular belief, employees with low levels of product/industry knowledge and low experience benefit the most from leadership behaviors that are empowering, whereas high-knowledge and experienced employees reap no clear benefit. The authors conclude with directions for future research and application. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Automatic EEG interpretation adaptable to individual electroencephalographer using artificial neural network

In view of the fact that the visual EEG interpretation could be a subjective task and may vary among the electroencephalographers, the main objective of this study was to develop an automatic EEG interpretation system which is adaptable to each electroencephalographer. The system adapted to each electroencephalographer would bring a close automatic EEG interpretation to that done by the electroencephalographer's visual interpretation. The adaptable automatic EEG interpretation was accomplished by using the constructive neural network with forgetting factor. The artificial neural network was constructed so as to give the integrative interpretation of the EEG based on the intermediate judgment of 13 items that characterized the visual interpretation. The developed method was evaluated based on the visually inspected EEG data of 37 patients by electroencephalographer‐A and the data of 20 patients by electroencephalographer‐B. The adapted ANN showed good agreement with each electroencephalographer's visual inspection. The proposed automatic EEG interpretation by use of the ANN can be a powerful assistant tool for individual electroencephalographers for their EEG interpretation.

一种适应性复制协议的研究与设计

传统的复制协议往往对如何适应遗留系统和引入复制技术对系统性能造成的影响方面考虑不够深入.本文在分析传统复制协议的基础上,提出了一种新协议.其设计采用复制实例数目可动态伸缩的逻辑令牌环结构,因而在满足可用性需求的前提下,可支持不同分布系统对适应性的需求,同时保证引入复制技术后系统的性能.文中详细论述了相应的系统模型和服务请求的处理,并通过与几种典型的传统复制协议的比较,证明了该协议的可行性.
