title: Computer graphic art of clothing

authors: Soo, Chin-En Keith

abstract: We are living in an ever-changing world, where new methods are being introduced to carry out the most staightforward task, where new inventions are being proposed to ease our daily operations, where new ideas are popping out at every corner. Since the dawn of time, mankind has been using innovation and creativity to survive and enhance life. With the use of technology, it has enabled more possibility and more significant endeavour. Now and forever, we are dependant on technology, that has played a substantial role in our design solutions, which inescapably affect every one of us.

title: In-kernel passive measurement of the performance impact of hidden terminals in 802.11 wireless networks

authors: Raynel, Scott McKenzie

subjects: computer science

abstract: The negative performance impact of the presence of hidden terminals in wireless networks has been well know for decades. Despite much research in the area, many deployed networks continue to suffer a performance penalty because of hidden terminals. Ad hoc wireless networks are particularly susceptible to hidden terminal collisions because there are fewer opportunities to plan the network in a way that avoids or reduces the number of hidden terminals. Measuring the presence of hidden terminals and the impact they are having on performance is difficult, especially in a network of many nodes. Without such measurements, the users and operators of wireless networks can not tell if performance problems are caused by hidden terminals or some other problem. We introduce new methodology that can detect the presence of hidden terminals and estimate the performance impact they are causing. The methodology requires no additional hardware and is suitable for wide scale deployment and long term operation. The approach is based on in-kernel instrumentation of the wireless network stack. The design, implementation, and testing of the approach are covered. Results from in-lab testing and the measurement of a live commercial 802.11 network are also presented, including a case study where performance was significantly improved.

title: Differential trends in the compression of mortality: Assessing the antecedents to current gaps in health expectancy in New Zealand

authors: Pool, Ian

subjects: New Zealand

abstract: Health Expectancies (HEs) for New Zealand show significant differentials between Maori and non-Maori, but also by gender and period. These differentials correlate with findings from both generation and synthetic life-tables relating to New Zealand’s epidemiologic transition. At the beginning of that transition quartile 1 (Q(1)), and Median (Med) d(x) values were close and centred at young ages; during the transition the gap became very wide; at the transition’s end the gap again narrowed. Cohort and synthetic trends in d(x), l(x), M, Qs and Meds are reviewed and linked to recent HEs. Data point to epidemic polarisation. Cohort analysis allows the evaluation of the role of past experiences on the recent HEs, and thus point to possible strategies for reducing gaps in both d(x), and HEs.
