Traffic and related selfdriven manyparticle systems
, 2000
"... Since the subject of traffic dynamics has captured the interest of physicists, many surprising effects have been revealed and explained. Some of the questions now understood are the following: Why are vehicles sometimes stopped by ‘‘phantom traffic jams’ ’ even though drivers all like to drive fast? ..."

Universal Dynamic Synchronous SelfStabilization
"... We prove the existence of a "universal" synchronous selfstabilizing protocol, that is, a protocol that allows a distributed system to stabilize to a desired nonreactive behaviour (as long as a protocol stabilizing to that behaviour exists). Previous proposals required drastic increases in ..."

Noise Tolerance of the Universal Dynamic Control Law

Both the Universal Dynamic Control Law (UDCL) advocated by this authorand the classical High Gain Integral Control Law (HGPICL) are robust controllers in the sense that they have the ability to approximately honor userspecified control goals without the need of detailed knowledge of the syste ..."

Quantitative universality for a class of nonlinear Transformations
 J. Statistical Physics
, 1978
"... A large class of recursion relations xn+l = Af(xn) exhibiting infinite bifurcation is shown to possess a rich quantitative structure essentially independent of the recursion function. The functions considered all have a unique differentiable maximum 2. With f(2) f(x) ~ Ix 21 " (for Ix 21 su ..."

Towards Developing Universal Dynamic Mapping Algorithms
 In Proceedings of the Seventh IEEE Symposium on Parallel and Distributed Processing
, 1995
"... We investigate the problem of mapping dynamically generated tasks onto the processors of an MIMDsystem. Our main concern is to construct an algorithm which can be integrated in distributed runtime systems like PVM or MPI. An algorithm which is suitable for this purpose has to be scalable for massiv ..."

Quantum groupoids associated to universal dynamical Rmatrices
, 1999
"... By using twist construction, we obtain a quantum groupoid D⊗qUqg for any simple Lie algebra g. The underlying Hopf algebroid structure encodes all the information of the corresponding elliptic quantum groupthe quasiHopf algebras as obtained by Fronsdal, Arnaudon et. al. and Jimbo et. al.. Groupoïd ..."

Version française abrégée Il y a, depuis peu, un intérêt grandissant pour l’équation de YangBaxter quantique universelle, aussi connue sous le nom d’équation de GeravaisNeveuFelder: R12(λ + �h (3))R13(λ)R23(λ + �h (1) ) = R23(λ)R13(λ + �h (2))R12(λ).

Flavor universal dynamical electroweak symmetry breaking,” Phys
 Rev. D59
, 1999
"... The top condensate seesaw mechanism of Dobrescu and Hill allows electroweak symmetry to be broken while deferring the problem of flavour to an electroweak singlet, massive sector. We provide an extended version of the singlet sector that naturally accommodates realistic masses for all the standard ..."

Inhomogeneous iterated function systems are natural generalisations of the classic iterated function systems, commonly used to generate examples of fractal sets. The key difference is, one begins with a fixed ”condensation ” set which is then dragged into the construction. Such systems have applications in image compression in situations where one wants to produce an image with lots of similar images at different scales, like a flock of seagulls or a forest. I will review some structural properties of these attractors and go on to discuss their dimension theory. Some of this talk will be joint work with Simon Baker (Reading) and Ándras Máthe ́ (Warwick).
