In this paper, we propose to solve the linear multicommodity flow problem using a partial Lagrangian relaxation. The relaxation is restricted to the set of arcs that are likely to be saturated at the optimum. This set is itself approximated by an active set strategy. The partial Lagrangian dual is solved with Proximal-ACCPM, a variant of the analytic center cutting plane method. The new approac...

Motivated by emerging battery-operated applications that demand intensive computation in portable environments, techniques are investigated which reduce power consumption in CMOS digital circuits while maintaining computational throughput. Techniques for low-power operation are shown which use the lowest possible supply voltage coupled with architectural, logic style, circuit, and technology op...

A method for efficiently selecting the operating modes within a block-based multi-mode video compression system is described. For a given image region, the optimum combination of modes is selected so as to minimize the overall distortion for a given bit-rate budget. Necessary conditions for optimizing the encoder operation are derived within a rateconstrained product code framework [I]. When ra...

The advent of New Zealand’s world-leading Digital Strategy underpins the increasing importance of ICTs in community settings. It also marks a significant change in government policy and the first time a government has adopted a whole of government approach to ICTs. This article provides a personal view of the policy process for creating the Digital Strategy, presented by one of the participants...

This paper will discuss recent initiatives to encourage the development of broadband networks in New Zealand. It is widely believed that the availability of good quality broadband will lead to improved economic development at the regional level. This paper considers the role played by both national and regional government in improving access to broadband. At a national level the government has ...

Organizations are increasingly adopting digital strategies and investing heavily in digital technologies and initiatives. However, to date, there does not appear to be a clear understanding of digital strategies and their purpose, which forms the motivation for this research. This research-in-progress study aims to address this research gap by exploring 1) the various conceptions of digital str...

•Many parents use multiple monitoring strategies in different combinations over time to monitor their adolescents.•Adolescents of parents who use multiple strategies reported greater risk involvement.•Parents who solicited information only from adolescents had greater knowledge and adolescent disclosure.
