title: Clean lakes - What value? What cost?

authors: Mueller, Hannah

abstract: Kia ora everyone and thank you so much for making it back to the last session of this wonderful symposium. Thank you so much to the LakesWater Quality Society for inviting me here to speak today. I am excited by the opportunity to share with you some of the findings of my PhD research that I finished earlier this year.

title: Impact of circadian tuning on the illuminance and color uniformity of a multichannel luminaire with spatially optimized LED placement

authors: Abeysekera, Sanush K.

subjects: Science & Technology

abstract: Potential advantages offered by multichannel luminaires with regards to spectral tuning are frequently overshadowed by its design challenges, a major one being the non-uniformity in illuminance and color distribution. In this paper, we present a formulation using genetic algorithm (GA) to optimize the Light Emitting Diode (LED) placement, yielding 40% superior uniformity in illuminance and color distributions compared to existing analytical formulations, substantially reducing the reliance on optical design for this purpose. It is specifically shown that our approach is employable for circadian tuning applications, even when heavily constrained by industry specifications on panel size and minimum LED separation.

title: Tāwharautia Aotearoa

authors: Maxwell, Te Kahautu

abstract: Tāwharautia Aotearoa was composed in opposition to the National Governments attempt to remove Section 9 of the Principles of the Treaty of Waitangi which would give the Government power to sell State assets. Performed by Ōpōtiki Mai Tawhiti at the Te Matatini World Championship Kapa Haa Competition 2013.
