A Geometric Characterisation of Resonance in Hopf Bifurcation from Relative Equilibria

We give a new characterisation of resonance in Hopf bifurcation from relative equilibria in systems with compact symmetry group. This characterisation provides a full geometric explanation of the resonance phenomenon. In addition, we develop techniques based on normal form theory to give a complete solution to the associated bifurcation problem.

An Adaptive System Framework for Surface Characterisation

Surface features have been recognised to be significant in many fields and the characterisation techniques are being constantly improved. The surface characterisation systems are developed by various instrument companies and institutions. However, the lack of good extensibility, reusability and maintainability is a serious obstacle to the system innovation. Component based software development ...

Uniform Procedures in Uncountable Structures

This paper contributes to the general program of extending techniques and ideas of effective algebra to computable metric space theory. It is well-known that relative computable categoricity (to be defined) of a computable algebraic structure is equivalent to having a c.e. Scott family with finitely many parameters (e.g., [1]). The first main result of the paper extends this characterisation to...

Phase Locked System Design and Measurement Tutorial Consisting of Physical Hardware and Co-simulation Environment

Phase locked loop based feedback techniques are used in a variety of system level timing, control and communication applications. Re-configurable hardware and associated simulation models have been developed with an emphasis towards teaching the fundamentals of Phase locked loop systems. The material is hardware focussed and reinforces, control system theory, characterisation, design, and model...
