The attractivity properties of the set of equilibria of a special class of homogeneous dynamic economic systems are examined. The nonlinearity of the models and the presence of eigenvalues with zero real parts make the ...

Subdaily, annual maximum rainfall series from a number of locations about Australia are analysed to determine how extreme bursts at one duration coincide with those at another duration. Burst patterns for sites at Darwin ...

In this paper we consider the FunctioneBehavioureStructure model of designing in the version as developed by John Gero and collaborators. We identify two problems: the absence of a stable definition of function, and ...

Linear bilevel programming theory has been studied for many years by a number of researchers from different aspects, yet it still remains to some extent unsatisfactory and incomplete. The main challenge is how to solve ...

In this paper distributions are identified which suitably fit log-returns of the world stock index when these are expressed in units of different currencies. By searching for (I best fit in the class of symmetric generalized ...

Welded wire fabric (WWF) is commonly used in reinforced concrete slabs. In Australia, such steel is classified as Class L - low ductility (ASINZS467 1-2001). Typically, the strain at peak stress (termed the uniform ...

We consider families of linear, parabolic PDEs in n dimensions which possess Lie symmetry groups of dimension at least four. We identify the Lie symmetry groups of these equations with the (2n+1)-dimensional Heisenberg ...

This paper highlights the importance of timing specifications in empirical market microstructure studies. Small changes in the data matching process and the timing specification of economic variables can significantly alter ...
