title: Stability analysis and experimental validation of the supercapacitor-assisted low-dropout regulator

authors: Subasinghage, Kasun

abstract: The supercapacitor-assisted low-dropout (SCALDO) regulator is a unique new design approach to develop high efficiency, high current and low noise DC–DC converters, where a supercapacitor (SC) is used in the series path of a low dropout (LDO) regulator to act as a lossless voltage dropper. In the published literature, there has been much discussion about the stability of an LDO regulator, where different approaches are applied to frequency compensate depending on the LDO architecture. Given the case that the SCALDO technique is a combination of an LDO regulator and an SC, this study presents an analysis and experimental validation of the stability, based on a 12–5 V SCALDO prototype, proving that the effect of the SC energy recovery method does not make the overall regulator carry a stability issue in general.

title: Sale of Goods Contracts and the Requirement of Fitness for Purpose in the Sale of Goods Act 1908

authors: Manyam, Joel

abstract: In general terms, the law of Contract is a set of rules designed to give legal effect to private bargains. Parties are free to contract on any matter they choose and on any terms they prefer, subject only to any limitations imposed by statute or by common law rules of public policy. The law recognises the paramountcy of this freedom of choice as to promises made in that, once parties have exercised their choice of reaching an agreement, the law may be used to enforce the agreement so reached, subject to the limitations mentioned.

title: Re-designing the national imaginary: The development of Matariki as a contemporary festival

authors: Hardy, Ann

subjects: Aotearoa/New Zealand

abstract: This article considers the factors shaping the contemporary redevelopment in Aotearoa/ New Zealand of the indigenous commemoration of the rising of the constellation Matariki as a marker of seasonal change.  Through interviews with producers of media materials celebrating Matariki, it examines the ideological, cultural, and economic factors determining the encoding of the materials, investigating in particular the ways in which Matariki can resource a marketplace for spiritual commodities.
