半环式传感型骨外固定器的力学特性实验

通过对尸胫骨 -传感器骨外固定器系统的动、静刚度及应力遮挡率进行了实验研究 ,表明半环四针传感型骨外固定器较两针型的刚度大 ,因此在骨愈合初期、粉碎性骨折宜采用四针结构 ,以避免错位、成角 ;愈合中后期用两针结构 ,以减小应力遮挡

Modeling and Control of Active Suspensions for MDOF Vehicle

The conventional method for analyzing active suspension control for a vehicle is only to analyze a quarter or half car with a lower order degree-of-freedom (DOF) model, but such models do not actually model practical applications. Accurate models of a suspension control system require a multi-degree-of-freedom (MDOF) vehicle model with a detailed model of the controller. An MDOF model was developed including the influence of factors such as the engine, the seats, and the passengers to describe vehicle motion using a reduced order model of the controller designed by using the H∞ control method. The control system performance has been investigated by comparing the H∞controller with a linear quadratic (LQ) controller.     

Nonsynchronous Trading Model and Return Analysis

Nonsynchronous trading is one of the hot issues in financial high-frequency data processing. This paper extends the nonsynchronous trading model studied in [1] and [2] for the financial security, and considers the moment functions of the observable return series for the extended model. At last. the estimators of parameters are obtained.
