In this paper, the sustainability of public debt is interpreted as the result of the interaction of fiscal policy with the economic environment, and not as a statistical concept as in most of the recent literature. If debt must not explode over time, policy makers have to respond to the changing conditions in the macroeconomic environment. This paper defines the conditions which will ensure com...

This bulletin is based on research conducted by Professor Gavin Wood and Dr Melek Cigdem at the AHURI Research Centre—RMIT University, and Ms Deb Batterham and Professor Shelley Mallett at Hanover Welfare Services. The research examined, for the first time, the geography of homelessness in Australia and its relationship to potential structural drivers of homelessness (specifically housing and l...

This report addresses the problem of jointly scheduling tasks with both hard and soft time constraints. We present new analysis which builds upon previous research into slack stealing algorithms. Our analysis determines the maximum processing time which may be stolen from hard deadline periodic or sporadic tasks, without jeopardising their timing constraints. It extends to tasks with characteri...

In this paper, we present Slack Stealing Job Admission Control (SSJAC)|a methodology for scheduling periodic rm-deadline tasks with variable resource requirements, subject to controllable Quality of Service (QoS) constraints. In a system that uses Rate Monotonic Scheduling, SSJAC augments the slack stealing algorithm of Thuel et al with an admission control policy to manage the variability in t...

Slow and accurate finger and limb movements are essential to daily activities, but the underlying mechanics is relatively unexplored. Here, we develop a mathematical framework to examine slow movements of tendon-driven limbs that are produced by modulating the tendons’ stiffness parameters. Slow limb movements are driftless in the sense that movement stops when actuations stop. We demonstrate, ...

Innovations are important for the development of firms and whole economies. Several theoretic approaches are therefore dealing with innovation and the motivation of firms to motivate. The Resource-based View of the Firm views innovations to be motivated by the use of slack resources while the Behavioral Theory of the Firm predicts problemistic search as an important motivation for innovative ma...
