title: A Breathing Stabilization System

authors: Ling, Heping

subjects: Breathing Stabilization System

abstract: Breathing Stabilization System is a new idea and method. The purpose of this system is to produce a device to control a patient’s breathing for gated radiotherapy.

This thesis focuses on building a simple Breathing Stabilization System that includes five solenoids, a power supply and five force sensors to build up the whole system.

Significantly, this thesis will introduce the modeling of solenoids in detail that include how to build a mathematical model of the solenoids. The simulation of the electromagnetic in professional multi-physics software COMSOL will also be explained.

To drive the solenoid system, a voltage-to-current converter is used. This part will be introduced as well as the operational amplifier circuit used by the force sensors.

title: The distributional impact of KiwiSaver incentives

authors: Gibson, John

subjects: distributive impact

abstract: New Zealand’s approach to retirement incomes profoundly changed with the recent introduction of KiwiSaver and its associated tax incentives. Previous policy reduced lifetime inequality but KiwiSaver and its tax incentives will increase future inequality and lead to diverging living standards for the elderly. In this paper we evaluate the distributional effects of these tax incentives. Using data from a nationwide survey conducted by the authors, we estimate the value of the equivalent income transfer provided to individuals by the tax incentives for KiwiSaver participation. Concentration curves and inequality decompositions are used to compare the distributive impact of these tax incentives with those for New Zealand Superannuation. Estimates are reported for both initial and lifetime impacts, with the greatest effect on inequality apparent in the lifetime impacts.

title: Te Ahi Kā

authors: Temara, Pou

subjects: Ahi kā

abstract: Ko te urutaumatua o tēnei tuhinga, ko te matapaki i te ahi kā. He aha tēnei tikanga? I pēhea i ara ake ai? He aha ōna mātāpono, ōna taipitopito? Koia te tūāpapa mō te tuhinga nei. Tuarua, ko te wānanga i te tikanga Māori me ōna rerenga pērā i te whakapapa. Ko te pātai ka puta i tēnei wāhanga o te wānanga ko tēnei nā, he aha te wāhi o te whakapapa ki te ahi kā? Ko te ngako o tēnei tuhinga ko te wetewete i te tikanga ahi kā kia whai tikanga ai te whakataukī nei, ‘ko te ahi kā te mana o te hapū ki te whenua’.
