This paper examines the potential for e-petitions to enhance the political engagement function of petitioning and assesses the procedural and technical requirements that have to be taken into account in planning an e-petition system.

Just months after chief executive, Larry Marshall, shocked the global scientific community by changing the CSIRO's focus from climate change research to climate change mitigation, Federal Science Minister, Greg Hunt, has ordered the national science body to re-instate climate science as a core priority. He says the move represents the direction and priorities of the...

The increased penetration of residential air-conditioners (AC); specifically vapor compression types, is regarded as one of the foremost causes of a dramatic rise in critical peak electricity demands requiring corresponding upgrades of electricity infrastructures. These upgrades requires heavy investments, consequently, driving up electricity prices. Solar air-conditioning systems can reduce this trend, but current vapor-compression air-conditioners...

To combat increasing electricity prices due to the high operating costs of conventional reverse cycle air-airheat pumps (RC-AA-HP), they can be powered by standalone PV systems as a radical demand side energy management solution. However, the heavy power consumption of their compressors necessitates very large and expensive standalone hotovoltaic (PV) systems. Alternatively, reversible air-water heat...

In a society that’s now reliant on cyberspace for everyday life, and when everything from cars, electricity grids and dams to weapons systems is connected to a network, the potential effects of malicious or aggressive actions in cyberspace warrant some justified concern. This paper examines the application of deterrence concepts to cyberspace, discusses cybersecurity implications...
