Introducing new technologies poses a particular challenge to the players involved in a project. For a successful low energy building, a new design process is required and players must assume new and additional responsibilities. Hypocaust systems, where conditioned or non-conditioned air is passed through ducts within the concrete floor or ceiling of a building prior to its delivery to the rooms, are starting to appear in new buildings in Australia. This paper describes the lessons learned from the early experiences with a hypocaust system, installed in a new building in Melbourne. It concludes that a more cooperative process among all those involved in introducing and using a new 'technology' is essential if the problems described are to be avoided or at least minimized.

A planar polynomial differential system has a finite number of limit cycles. However, finding the upper bound of the number of limit cycles is an open problem for the general nonlinear dynamical systems. In this paper, we investigated a class of Liénard systems of the form x'=y, y'=f(x)+y g(x) with deg f=5 and deg g=4. We proved that the related elliptic integrals of the Liénard systems have at most three zeros including multiple zeros, which implies that the number of limit cycles bifurcated from the periodic orbits of the unperturbed system is less than or equal to 3.

In some Queensland universities, Information Systems academics have moved out of Business Faculties. This study uses a pilot SWOT analysis to examine the ramifications of Information Systems academics being located within or outside of the Business Faculty. The analysis provides a useful basis for decision makers in the School studied, to exploit opportunities and minimise external threats. For Information Systems academics contemplating administrative relocation of their group, the study also offers useful insights. The study presages a series of further SWOT analyses to provide a range of perspectives on the relative merits of having Information Systems academics administratively located inside versus outside Business faculties.
