title: Fostering energy awareness in residential homes using mobile devices

authors: Reinhart, Florian

subjects: Mobile technology

abstract: There is considerable global effort being made towards identifying ways of reducing energy consumption to cope with growing demands. Although there is potential for energy saving in many sectors, our focus is on reducing energy consumption in residential homes. We have developed a system which combines home automation and energy usage monitoring technologies. The system offers a range of tools designed for mobile devices to assist users with monitoring their energy usage and provides mechanisms for setting up and controlling home appliances to conserve energy. In this paper we describe our system and a user study we have conducted to evaluate its effectiveness. The findings of the study show the potential benefits of this type of mobile technology.

title: Numerical simulations of wave setup over barred beach profiles: Implications for predictability

authors: Sephens, Scott A.

subjects: wave transformation

abstract: Numerical simulations of cross‐shore wave transformation and associated wave setup were performed for 100,000 realistic combinations of wave height, period and beach profile. Results of numerical simulations were compared to a widely‐used empirical predictor of wave setup and the outcome was a large variability in setup relative to that calculated by the empirical predictor. The variability, comparable in magnitude to the scatter around the empirical predictor developed with field observations, arose from unaccounted‐for wave energy dissipation over the cross‐shore profile. The beachface slope commonly used in empirical predictors can be a poor descriptor of wave transformation across the beach profile where most of the wave energy dissipation and setup generation occurs. Shoreline setup appears to be far more dependent on accurate characterisation of the offshore profile (e.g. bar location and depth) than the beach face slope.

title: Te whakaihonga: He tikanga tapahi makawe i te ao Māori

authors: McDonald, Rangihurihia Ann

subjects: Tapahi makawe

abstract: E ai ki te Māori, mai anō i a Māui Pōtiki, kua tapahia e te pouaru, e te kirimate, ngō rātou makawe i te tangihanga. He reureu, he tiotio, he pakipaki taha ngētehi o ngā tohu weriweri nei, i tauawhi, i whakaū i te aroha ki te mate. I ngētehi wā, he whakamaumahara, he take whakariri i te ngākau, he utu i te tangi kino o te manawa. Mutu kau ana te tangihanga, ko te heuenga hoki i te whare tauā, ki te wai whakaika. Ko ngētehi take ngēnei o te tapahi makawe a te kirimate, otirā, ko te tino whāinga o tēnei tuhinga whakapae. He whakapono makawe anō i whakaemingia, nā te rangahau mātātuhi, ko ngā pūrākau, ngā mōteatea, ngā whakataukī anō hoki a ngā tūpuna. He tirohanga kaumātua i kohikohingia nā roto mai o te uiui. Waiho mai ana ko ngā tikanga tawhito mō te tapahi i te uru tapu o te tangata, ki te ao tūroa.
