Intervention trials such as studies on smoking cessation may observe multiple, discrete outcomes over time. When the outcome is binary, participant observations may alternate between two states over the course of the study. The generalized estimating equation (GEE) approach is commonly used to...

Previous studies have linked social participation and community levels of trust with improved health status. We examined the associations between levels of community participation, self-reported community ratings (trust), and health within a public health surveillance survey conducted in Kansas...

Purpose – The purpose of this paper is to focus on the accurate and steady control on trajectory tracking for wafer transfer robot, suppress the vibration and reduce the contour error. Design/methodology/approach – The wafer transfer robot dynamic model is modeled. Through analyzing the...

Purpose – Wafer transfer robots play a significant role in IC manufacturing industry and the end effector is an important component of the robots. The purpose of this paper is to improve transfer efficiency of a wafer transfer robot through study of its end effector, and at the same time to...
