"A novel bath lily-like graphene sheet-wrapped nano-Si composite synthesized via a simple spray drying process exhibits a high reversible capacity of 1525 mAh g(-1) and superior cycling stability, which could be attributed to a synergistic effect between highly conductive graphene sheets and active nanoparticles in the open nano/micro-structure."


Evaluating Mediated Perception Of Narrative Health Messages: The Perception Of Narrative Performance Scale, Jeong Kyu Lee, Michael L. Hecht, Michelle Miller-Day, Elvira Elek Jan 2011

Narrative media health messages have proven effective in preventing adolescents' substance use but as yet few measures exist to assess perceptions of them. Without such a measure it is difficult to evaluate the role these messages play in health promotion or to differentiate them from other message forms. In response to this need, a study was conducted to evaluate the Perception of Narrative Performance Scale that assesses perceptions of narrative health messages. A sample of 1185 fifth graders in public schools at Phoenix, Arizona completed a questionnaire rating of two videos presenting narrative substance use prevention messages. Confirmatory factor analyses …


Robust And Intelligent Control Methods To Improve The Performance Of A Unified Power Flow Controller, C Benachaiba, Ahmed M. Haidar, M L. Doumbia Jan 2011

Robust And Intelligent Control Methods To Improve The Performance Of A Unified Power Flow Controller, C Benachaiba, Ahmed M. Haidar, M L. Doumbia

Faculty of Engineering and Information Sciences - Papers: Part A

The important factor disturbing the modern power systems today is load flow control. The Unified Power Flow Controller (UPFC) is an effective way for controlling the power flow and can provide damping capability during transient conditions. The UPFC is controlled conventionally using PI controller. This paper presents two robust controllers to improve the performance of the UPFC. The first is a RST controller based on the principle of pole placement and the second is an intelligent controller based on the principle of fuzzy logic optimized by Genetic Algorithm (GA).

Performance Analysis Of Numerical Integration Methods In The Trajectory Tracking Application Of Redundant Robot Manipulators, Emre Sariyildiz, Hakan Temeltas Jan 2011

Performance Analysis Of Numerical Integration Methods In The Trajectory Tracking Application Of Redundant Robot Manipulators, Emre Sariyildiz, Hakan Temeltas

Faculty of Engineering and Information Sciences - Papers: Part A

Differential kinematic is one of the most important solution methods in robot kinematics. The main advantage of the differential kinematic method is that it can be easily implemented any kind of mechanisms. Also, an accurate and efficient kinematic based trajectory tracking application can be easily implemented by using this method. In differential kinematic method, we use Jacobian as a mapping operator in the velocity space. Inversion of Jacobian matrix transforms the desired trajectory velocities, which are the linear and angular velocities of the end effector, into the joint velocities. The joint velocities are required to be integrated to obtain the …


Race Matters: Whether We Know It, Or Like It, Or Not: Implicit Racial Attitudes And Their Effect On Accounting-Based, Balanced Scorecard Performance Evaluations, David R. Upton, Cecil E. Arrington Jan 2011

Race Matters: Whether We Know It, Or Like It, Or Not: Implicit Racial Attitudes And Their Effect On Accounting-Based, Balanced Scorecard Performance Evaluations, David R. Upton, Cecil E. Arrington

One of the dominant themes in critical accounting theory over the past two decades has to do with the relation between the construction of human identities and accounting discourse and practices. Though with strong antecedents in Marxist –inspired critique of ideology, genealogical studies (e.g., Miller & O’Leary, 19XX), deconstructive studies (e.g., Shearer & Arrington, 19XX), and critical-rational studies (e.g., Power & Laughlin, 19XX) are examples of different theoretical and methodological ways to probe the constructive force of accounting over human identity and subjectivity. This paper offers a fourth approach grounded in social-cognitive concerns with ways in which implicit attitudes, or …


Disproportional Ownership Structure And Pay–Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary Tian Jan 2011

Disproportional Ownership Structure And Pay–Performance Relationship: Evidence From China's Listed Firms, Jerry Cao, Xiaofei Pan, Gary Tian

This paper examines the impact of ownership structure on executive compensation in China's listed firms. We find that the cash flow rights of ultimate controlling shareholders have a positive effect on the pay–performance relationship, while a divergence between control rights and cash flow rights has a significantly negative effect on the pay–performance relationship. We divide our sample based on ultimate controlling shareholders' type into state owned enterprises (SOE), state assets management bureaus (SAMB), and privately controlled firms. We find that in SOE controlled firms cash flow rights have a significant impact on accounting based pay–performance relationship. In privately controlled firms, …
