Analysis was based on data from 275 high school students aged 14 to 18. The hypothesized multidimensionality of the construct was confirmed for both boys and girls using a second-order(More)
Introduction As track density in tape recording systems increases, the need for high performance control becomes crucial due to significant high frequency disturbances such as lateral tape motion, inner track variability, servo track variability, noise and input saturation of the servo actuator. An essential step in designing high performance model based(More)
