The need to suppress vibration in large space structures is a continuing problem during design. Active control of structural vibration is one method that can be used to achieve lightweight structures with desirable damping characteristics. In this pa

A chromosomal protein antigen specific for human granulocytes is described. The antigen is present in large amounts in granulocytes and in granulocytic leukaemia. It is absent from HeLa cells, human fibrosarcoma cells and human lymphocytes. It is, ho

Additional insight is provided into the use of the Doyle-Stein (1979, 1981) technique in aeroelastic control problems by examining the application of the method to a flutter control problem. The system to be controlled consists of a full-size wind tu

The DNA-binding site of a previously characterized non-histone chromosomal protein antigen(s) from HeLa cells was investigated for its species specificity. Treatment with large amounts of micrococcal nuclease abolishes immunoactivity, which can then

Nominal roll control laws were designed, implemented, and tested on an aeroelastically-scaled free-to-roll wind-tunnel model of an advanced fighter configuration. The tests were performed in the NASA Langley Transonic Dynamics Tunnel. A parametric st

This paper describes the application of Linear Quadratic Gaussian (LQG) methodology to the design of active control systems for suppression of aerodynamic flutter. A full-size wind tunnel model of a supercritical wing with associated sensors and actu
