A coupled rotor-fuselage aeroelastic analysis using complex rotor modes
A new modal method capable of analysing the aeroelastic response of rotorcraft in both steady and manoeuvring flight is developed. Particular emphasis is given to the correct modelling of the dynamic interactions between the rotor and the fuselage. This is achieved via the use of complex rotor …

Fast time domain simulation for large order hybrid systems
… subsystems, simulates them with state transition formula and superposes the responses by using the linearity property of LTI systems. A similarity transformation can first be employed to obtain the modal canonical form of the system. The modal form can then be divided into subsystems with …

Reduced-Order Reference Models for Adaptive Control of Space Structures
… modeling (in particular balanced-state and modal techniques) as applied to structural finite element models, this work produced tools for visualizing the relationship between the modes of a model and the states of its balanced representation.</p> <p>Specifically, error contour and mean error …

How infant massage enhances pedagogical attachment in families facing challenging circumstances
… through an innovative matrix of approaches to informed consent, and co-interpretation of the data with families. Infant massage was found to facilitate a unique multi-modal form of joint communication which I termed ‘visceral interaction’. This connectivity was set in a series of delicately …

Performance assessment and enhancement of precision controlled structures during conceptual design
… It is advantageous to assess the performance of initial concepts of these precision systems early in the design stage to aid in the requirements flowdown and resource allocation process. A complete end-to-end performance assessment methodology is developed which incorporates …
