discovered that the enzyme tyrosine hydroxylase undergoes a form of hierarchical phosphorylation not
previously reported. Here we examine hierarchical phosphorylation in rat and human tyrosine
hydroxylase and its functional consequence in intact cells. The approaches and methods developed will
also be applicable to investigation of hierarchical phosphorylation in other proteins.

Administering Institution: The University of Newcastle
Summary:
A fundamental discovery of the first decades of computer science is that completely efficient (polynomial
time) algorithms probably do not exist for thousands of natural computational problems. The project will
result in new methods for designing and analyzing algorithms for hard problems with natural parameters,
and in improved algorithms for these problems.

Title: Nano-Particle Suspension Behaviour in Salt Solutions: Effect of Ion Hydration and
Attractive Forces
2003 : $66,000

Category: 2914 - MATERIALS ENGINEERING
Administering Institution: The University of Newcastle
Summary:
Understanding and controlling the flow behaviour of nano-particle suspensions is crucial to the
processing of ceramics with nano-scale features. Interparticle forces influence the flow behaviour and
depend upon the the adsorption of ions to the particle's surface. The proposed research investigates the
effect of ion hydration and surface type on ion adsorption, the resulting attractive forces and suspension
flow behaviour. The outcomes of the project have potential for significant increase in fundamental
understanding of the relationship between ions, surfaces and forces. The benefits of this knowledge
include producing nano-ceramics with improved properties and better understanding biopolymer
behaviour.

Title: Towards a unified theory of constrained control and estimation

Category: 2301 - MATHEMATICS
Administering Institution: The University of Newcastle
Summary:
The project will investigate the implications of duality and other connections between constrained control
and estimation. We believe that the research will result in a richer understanding of these problems. In
particular, we envisage an impact in at least four areas: (i) Computational issues, i.e., development of
more efficient algorithms for constrained problems. (ii) Geometry of constrained problems, by extending
recent results pertaining to constrained control to estimation problems. (iii) Problems with mixed
constraints, for example, interval and finite set constraints. (iv) Fundamental limitations imposed by
constraints to filtering and control problems.
