Singular and Analytic Perturbations, Slow and Fast Time Scales in Control Theory and Viability Theory and their Applications. We propose an innovative approach to several important classes of mathematical problems, whose data depend analytically on small perturbation parameters. Time scale problems, and, in particular, the interaction of two types of evolution, slow and fast, arise in many scientific domains (biotechnology, physics, engineering, etc).We expect to develop new techniques for analy ....Singular and Analytic Perturbations, Slow and Fast Time Scales in Control Theory and Viability Theory and their Applications. We propose an innovative approach to several important classes of mathematical problems, whose data depend analytically on small perturbation parameters. Time scale problems, and, in particular, the interaction of two types of evolution, slow and fast, arise in many scientific domains (biotechnology, physics, engineering, etc).We expect to develop new techniques for analysis and asymptotic optimisation of singularly perturbed control systems and Markov decision processes. In particular, we plan to establish links between general nonlinear optimal control problems with time average criteria and linear programming problems in the space of limit occupational measures generated by the underlying control system.Read moreRead less
Evolution of host relationships among the parasitic wasps inferred from morphology, DNA sequences and mitochondrial genome organisation. The parasitic Hymenoptera (wasps) are extensively used as biological control agents of agricultural and horticultural pests worldwide, but detailed information on their evolutionary relationships, how they have coevolved with major host groups, and the patterns of host relationships across various wasp families are lacking. This project will employ DNA sequence ....Evolution of host relationships among the parasitic wasps inferred from morphology, DNA sequences and mitochondrial genome organisation. The parasitic Hymenoptera (wasps) are extensively used as biological control agents of agricultural and horticultural pests worldwide, but detailed information on their evolutionary relationships, how they have coevolved with major host groups, and the patterns of host relationships across various wasp families are lacking. This project will employ DNA sequence data from 'new' genes, information on mitochondrial genome organisation, as well as morphology, to generate robust phylogenies for braconid and scelionid wasps that can be used to determine patterns of host utilisation and predict hosts for wasp groups where this information is currently unknown.Read moreRead less
A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli an ....A unified theory of performance in absolute identification tasks. The ability to identify stimuli is fundamentally important in human cognition and is studied in absolute identification tasks, where people must identify one out of a number of stimuli, varying on a single dimension, with an appropriate label. A remarkable finding is that people cannot reliably identify more than about seven different stimuli. This limit imposes severe practical restrictions on our ability to categorise stimuli and constitutes a perplexing problem for cognitive theory. This project involves an international collaborative effort by five leading researchers in mathematical psychology to develop a comprehensive, integrative model of human performance in absolute identification tasks.

Collision data for lighting industry and plasma modeling. The project's primary aim is to progress the design of more efficient
and environmentally friendly light sources. Given the number of light
sources in use worldwide even a small improvement in the efficiency
could lead to enormous benefits to society via reduction of energy
consumption. Design of new mercury-free light sources will eliminate a
major neuro-toxin pollution source. Collaboration with research groups
