title: Design and construction of a configurable full-field range imaging system for mobile robotic applications

authors: Carnegie, Dale A.

subjects: mobile robotic devices

abstract: Mobile robotic devices rely critically on extrospection sensors to determine the range to objects in the robot’s operating environment. This provides the robot with the ability both to navigate safely around obstacles and to map its environment and hence facilitate path planning and navigation. There is a requirement for a full-field range imaging system that can determine the range to any obstacle in a camera lens’ field of view accurately and in real-time. This paper details the development of a portable full-field ranging system whose bench-top version has demonstrated sub-millimetre precision. However, this precision required non-real-time acquisition rates and expensive hardware. By iterative replacement of components, a portable, modular and inexpensive version of this full-field ranger has been constructed, capable of real-time operation with some (user-defined) trade-off with precision.

title: Historicising Gerd Koch's Ethnographic Films on Tuvalu

authors: Goldsmith, Michael

subjects: Gerd Koch

abstract: Gerd Koch is probably best known for his studies of Tuvalu in the early 1960s, when it was still part of the Gilbert and Ellice Islands Colony. In the process of recording aspects of material and expressive culture on Niutao, one of the northernmost islands, he shot a series of black-and-white silent films. Fifteen of these films were archived at IWF Wissen und Medien in G ttingen, Germany, formerly the Institut f r den Wissenschaftlichen Film, as part of an encyclopaedic project reflecting mid-20th-century scientific and philosophical assumptions. What do these films tell us about Tuvalu and the histories of anthropology and ethnographic film-making in the Pacific? This paper proposes some answers by focusing on two films featuring styles of combat that are both called 'failima' yet are clearly different from each other.

title: Ka ora | Ka mate

authors: Apiata, Hāwea

abstract: Ekphrasis in response to the artwork 'Matariki' by Hariata Ropata-Tangahoe (Ngāti Toa, Ngāti Raukawa, Te Āti Awa). Written for the One Hundred Years exhibition held at RAMP Gallery, in celebration of the establishment of the first iteration of the technical college a century earlier in 1924. Alumni of the art program were invited to contribute works to the show and local writers were asked to respond to the art, with their works being published in the exhibition catalogue.
