introduction: a great percentage of aids infections occure in adolescence and youth. since that,studing and finding the most efficient teaching methods in order to improve their information ( knowledge) and attitude also to create o positive one and to creat preventive measures in the young and adolescent,is of great significance and priority. materials and methods: 7 school were picked randomy...

This study examined listener attitudes toward 7 speakers with dysarthria who implemented 3 speech supplementation strategies (topic cues, alphabet cues, and combined topic and alphabet cues) and a habitual speech control condition. Findings were similar, but not identical, to intelligibility results published in 2 earlier papers (K. C. Hustad, J. Auker, N. Natale, and R. Carlson, 2003; K. C. Hu...

In this report, a method for attitude control of statically-stable walking robots is developed such that slip is minimized when the body is leveled by using only the actuators which cause vertical link motions. If all legs of a walker have three independent nanslational degrees of freedom, then an attitude conhul method that uses all actuators may be used to level the body with no foot slippage...

The goal of the present study is to develop a decentralized coordinated attitude control algorithm for satellite formation flying. To handle the nonlinearity of the dynamic system, the problems of absolute and relative attitude dynamics are formulated for the State-Dependent Riccati Equation (SDRE) technique. The SDRE technique is for the first time utilized as a nonlinear controller of the rel...

A robust control allocation scheme is developed for rigid spacecraft attitude stabilization in the presence of actuator partial loss fault, actuator failure, and actuator misalignment. First, a neural network fault detection scheme is proposed, Second, an adaptive attitude tracking strategy is employed which can realize fault tolerance control under the actuator partial loss and actuator failur...

This paper presents results from the attitude control optimization for a small-scale helicopter by using an identified model of the vehicle dynamics that explicitly accounts for the coupled rotor/stabilizer/fuselage (r/s/f) dynamics. The accuracy of the model is verified by showing that it successfully predicts the performance of the control system currently used for Carnegie Mellon’s autonomou...
