title: Ranapia Mokena: son of Mokena Hou

authors: Hart, Philip

abstract: Little is known of the early life of Ranapia Mokena. He owned land close to Thames and acquired interests in other blocks, which provided him with some income, but he was never wealthy, as indicated by his being sued for a series of small debts. He invested in a small way in mining at both Thames and Te Aroha, and even worked in one claim. His life was most notable for being a deacon in the Church of England.
Ranapia was another example of a rangatira who supported the Crown, as was illustrated by his becoming a member of the Thames Native Rifle Volunteers. Childless, in his old age he brought up a niece’s daughter.

title: Te hau mihi ata mātauranga Māori and science - Cross cultural dialogue

authors: Joseph, Robert

abstract: The Te Hau Mihi Ata Mātauranga Māori and Science research project (the research project) will explore ways to link mātauranga Māori and western science. The purpose of the research project is to open a new creative knowledge space to unleash innovative thinking and cross-cultural connection that is unique to New Zealand which can be a source of untapped economic, social, environmental and cultural potential. The historic marginalisation of alternative value and knowledge systems has prevented quality engagement and dialogue between these two knowledge systems in New Zealand. The research project will develop, inter alia, a new inter-cultural dialogue process between Māori educated in western-based science and experts in mātauranga Māori.

title: Passive, fractional, battery equivalent-circuit model in time and frequency domains part 1: Linear model

authors: Farrow, Vance

abstract: Existing time-domain fractional model simulations of batteries are either limited to short time sequences, frequently less than 100 s, if truly fractional or use low order RC-ladder fractional approximations to reduce computational burden. Here we present an entirely-passive, truly fractional, equivalent-circuit model of a battery. We rely on a Reimann-Louiville fractional order differintegral to account for long time-scales out to 12 days. An analytical solution is provided for the differintegral, subject to the constraint of piecewise constant current. We validate our model fitting against a multi-day sequence of measured time domain data and EIS measured to 10 μ Hz. The spectral content of the current waveform is identified as a crucial factor. The full evaluation of fractional elements leads to residual error of voltage waveforms that is amongst the best in the literature despite the model having only five parameters. In the time-domain, a root-mean-square error (RMSE) as low as 2.8 mV is achieved while maintaining a frequency-domain RMSE of 14 % from measured impedance values over a span of 6 decades. The use of time-weighted regression is shown to be important to the time-domain fit.
