    H¿ model matching problem (MMP) for single-input/single-output (SISO) two frequency scale (TFS) systems is considered.
  • An x-ray diffraction method for measuring thicknesses of epitaxial thin films 

    Chaudhuri, J.; Shah, S.; Harbison, J. P. (IEEE, 1989-12)
    An x-ray diffraction technique capable of measuring the thicknesses of epitaxial thin films with high precision is described. The advantages of this method are that it is nondestructive, straightforward, and rapidly ...
  • Constrained pole placement using projective controls technique 

    Fousan, N. S.; Sawan, M. Edwin (IEEE, 1990-05-23)
    Projective controls method is used to place the poles of a closed loop system within a circle in the left half plane. The design procedure is noniterative and the solution is obtained via linear quadratic (LQ) design for ...
  • Physiological capacities of individuals with cerebral palsy 

    Fernandez, Jeffrey E.; Pitetti, Kenneth H.; Betzen, M. T. (Sage Publications, 1990-08)
    The physical work capacity (PWC) and the physiological response to stimulated tasks of nine ambulatory individuals with cerebral palsy (CP) were studied. Energy demand for each work task was determined by percentage of PWC ...
