Conformational dynamics control catalysis in disparate systems : structural insights from DNA repair and antibiotic biosynthetic enzymes
Chemical reactions allow biological systems to function. The majority of these biochemical reactions occur due to the work of protein catalysts known as enzymes. These biocatalysts are often thought of as pre-formed, static 'locks' that bind, and subsequently transform, their substrate molecule …

Control of the motion of nonholonomic systems
This dissertation deals with the control, guidance and stabilisation of nonlinear, non¬holonomic systems. It is shown that the kinematics of the system can be separated from the dynamics of the system by using successively two inverse dynamics type of transformations. This leads to a linear …

A neural network-based controller for a single-link flexible manipulator using the inverse dynamics approach
This thesis presents an intelligent strategy for controlling the tip position of a flexible-link manipulator. Motivated by the well-known inverse dynamics control approach for rigid-link manipulators, two multi-layer feedforward neural networks are developed to learn the nonlinearities of the …
