title: Displaying 3D images: algorithms for single-image random-dot

authors: Thimbleby, Harold W.

subjects: Machine learning

abstract: A new, simple, and symmetric algorithm can be implemented that results in higher levels of detail in solid objects than previously possible with autostereograms. In a stereoscope, an optical instrument similar to binoculars, each eye views a different picture and thereby receives the specific image that would have arisen naturally. An early suggestion for a color stereo computer display involved a rotating filter wheel held in front of the eyes. In contrast, this article describes a method for viewing on paper or on an ordinary computer screen without special equipment, although it is limited to the display of 3D monochromatic objects. (The image can be colored, say, for artistic reasons, but the method we describe does not allow colors to be allocated in a way that corresponds to an arbitrary coloring of the solid object depicted.) The image can easily be constructed by computer from any 3D scene or solid object description.

title: A Meta-Service for Event Notification

authors: Jung, Doris

subjects: computer science

abstract: The integration of event information from diverse event notification sources is, as with meta-searching over heterogeneous search engines, a challenging task. Due to the complexity of event filter languages, known solutions for heterogeneous searching cannot be applied for event notification 
In this paper, we propose the concept and design of a Meta Service for Event Notification. We define transformation rules for exchanging event filter definitions and event notifications between various event services and sources. We transform each filter defined at a meta-service into a filter expressed in the language of each event notification source. Due to unavoidable asymmetry in the semantics of different langues, some superfluous information may be delivered to the meta-service. These notifications are then post-processed to reduce the number of spurious messages. We present a survey and classification of filter languages for event notification, which serves as basis for the transformation rules. The proposed rules are implemented in a prototype transformation module for a Meta Service for Event Notification.

title: RE-AUTHORISING BICULTURAL EXPERIENCES: Listening to previously silenced voices

authors: Stubbings, Mary Ann

subjects: Education

abstract: "Nothing strengthens authority so much as silence."
Leonardo de Vinci

The principles of the Doctrine of Discovery, conceived 500 years ago, advocated absolute power and authority for European invaders to conquer and claim indigenous land. This shaped the converging of Māori/Settler relationships and validated the colonisation of Aotearoa New Zealand. 

This thesis contends that the historic and taken for granted power and privilege that has benefitted Pākehā, transpired through a reimagined, fabricated version of our separate and combined past. The study unearths ingrained Pākehā perspectives and stereotypes about Māori, and a rejection of their disparate culture and identity. It highlights the role of schooling in Aotearoa New Zealand as a tool of colonisation to erase the culture and identity of Māori and to maintain a world view that authorised power and privilege for the Settlers. 

The study challenges Pākehā to 'step up' by shattering the sphere of silence around our combined historical narratives. It urges us [Pākehā] to develop critical consciousness so we may reflect on the world, and our position within it.

Inherent in this research is the premise that for Aotearoa, New Zealand to devise a future based on respectful and equitable sharing of social, financial, cultural, spiritual, and physical resources and opportunities, our silenced history, authorised by the State through the procedures of colonisation, must be acknowledged.
