Active Control for Vibration Damping,ust control design. The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) control design technique is a particular robust design technique selected for use in designing a damping control system. A summary of LQG/LTR is given and numerical example using a two bay truss is presented.

Adaptive Control of Large Space Structures: Uncertainity Estimation and Robust Control Calibration,stem identification to obtain a nominal estimate of the plant transfer function. Non-parametric spectral methods are then used to obtain a frequency domian expression for model uncertainty. If the model uncertainty exceeds a specified frequency bound, which has been predetermined from the nominal mo

Unified Optimization of Structures and Controllers,lly stabilizing (optimal in some sense) feedback control law, a fundamental question is the following: ...? Of course, there are many interesting and significant issues raised by this question. The modeling process is always imperfect, among the several important sources of error are the following:

An Integrated Approach to the Minimum Weight and Optimum Control Design of Space Structures,dify the structural stiffness by changing the cross-sectional areas of the members in order to achieve a minimum weight structure and the desired distribution of the closed-loop eigenvalues and structural frequencies. The application of both methods is illustrated on truss structures.

The history of hemoglobin can be divided into three periods: the Classical period, the Modern period, and the Post-Modern period. I am inclined to include as the four major member

Under optimal conditions and at 25 C each molecule of enzyme catalyses the hydration of about 10 molecules of CO. per second. This observation which is well established, (Kernohan, 1965; Khalifah, 19

This property may be strongly influenced by the presence of non-S hemoglobins or by a second amino acid sub-stitution on either the β chain (hb C-Harlem (α.β..) (Bookchin et. Al., 1967) or the α chain (hb Memphis (α..) (Kraus et al., 1966). Furthe
