- Transport of motile plankton in synthetic turbulent flows (Surrey).
- Predictability of Uncertain Nonlinear Systems (Oxford)

The project covers aspects of the theoretical production of synthetic turbulent flows and the inclusion of stochastically swimming plankton, biased with a range of biological strategies. Recent research in this area (Bees, Sagues & Sancho, in prep.) will be built upon. The project will consist of theoretical fluid mechanics applied in a biological context. The student will be based in the BioMaths Group http://www.eim.surrey.ac.uk/maths/research/maths/BioMaths/ in the Department of Mathematics at the University of Surrey in Guildford and will interact with collaborators in the Physics and Physical Chemistry Departments at the University of Barcelona. There will be opportunities for the successful student to spend some time working in these institutions and there may also be the possibility of collaborating with experimentalists in France.

Prospective candidates should contact Dr. Martin Bees, without delay, at the address below (preferably by email).

The Oxford Centre for Applied and Industrial Mathematics (OCIAM) expects funding to support a D Phil Student in Mathematics. OCIAM has a strong research group in nonlinear dynamics and its applications in physical science and industry. The aim of this project is to study the dynamics of uncertainty under an ensemble of imperfect models and uncertain initial conditions in low-dimensional (< 400-D) systems. Questions of interest include issues of sampling in the space of all possible models, the optimal use of stochastic perturbations, and estimating fundamental limits of predictability in a given operational environment. Close links to both European and North American weather forecast centers will allow insights gained to be tested in practice (see the "Recent thesis" announcement of Isla Gilmour in this issue). Further information can be found at http://www.maths.ox.ac.uk/ociam. Students with a background in either nonlinear dynamics, statistics, or atmospheric science are encouraged to apply. Awards will be subject to the achievement of a first class honours degree. Applications should be received before 30 May 1999.

Application details can be obtained from

- NRC Fellowship in low speed gas turbine combustion (Propulsion Directorate).

An NRC fellowship to do research and develop code
for low speed gas turbine combustion is available at the
Propulsion Directorate. The work will focus on unsteady
combustion (including pulsed detonation wave combustion),
supercritical fuel modelling and combustion, combustion dynamic
instability, large eddy simulation for chemically reacting flows,
sub grid chemistry modelling and reduced chemistry modelling. The
duration is typically for two years, and research will be
performed at Wright Patt. It is expected that publications in
major conferences and journals will come out of this research.
More information is available at `http://www.nas.edu/rap/welcome.html`.
