title: A new structural model of effective thermal conductivity for heterogeneous materials with co-continuous phases

authors: Wang, Jianfeng

subjects: co-continuous

abstract: A new structural model for a heterogeneous material with multiple continuous phases is proposed. The corresponding equation for effective thermal conductivity was derived using three methods. The new model is substantially different from the conventional five fundamental structural models (Series, Parallel, two forms of Maxwell–Eucken, Effective Medium Theory). The model has two applications. First, as a new fundamental structural model to produce composite models using the combinatory rules previously proposed by J.F. Wang, J.K. Carson, M.F. North, D. J. Cleland, A new approach to modelling the effective thermal conductivity of heterogeneous materials, International Journal of Heat and Mass Transfer, 49 (17–18) (2006) 3075–3083. Second, to narrow the bounds of the effective thermal conductivity for heterogeneous materials where the physical structure can be characterised into general classes.

title: Document level interoperability for Collection Creators

authors: Bainbridge, David

subjects: computer science

abstract: Digital library interoperability for both documents and metadata is a critical and complex issue. Although many relevant standards have been developed, and continue to evolve, in practice things are not quite so easy as they seem. We have built a software environment called the Exchange Center that helps digital librarians manage the process of sourcing documents and metadata from various repositories, adding local content where necessary, and exporting the resulting collection into formats that are suitable for digital library repositories. This paper describes the software, which is built on Greenstone but does not require its use as the final digital library server.

title: Ki te kapu o takau ringa - In the Hollow of my Hand: Wānanga based Photographic Approaches to Place Representation

authors: Hill, Rodrigo

abstract: Ka matakitaki iho au ki te riu o Waikato
 Ano nei hei kapo kau ake maaku; 
Ki te kapu o taku ringa, 
“I look down on the valley of Waikato, 
As though to hold it  
In the hollow of my hand.
 The words above are from Māori King Tawhiao’s maioha (song poem), a representation of his love for his homelands of the Waikato and the region known today as the King Country. Now imagine a large-scale photograph: a close-up of cupped hands, holding an object carefully. The phrase above informs Professor Tom Roa and Dr. Rodrigo Hill’s current research project titled ‘Te Nehenehenui - The Ancient Enduring Beauty in the Great Forest of the King Country’. With this project still in its early stages the research team will present early and ongoing creative practice developments, discussions and ideas about photography practice, wānanga, and place representation. The project promotes the use of wānanga (forums and meetings of focus groups through which knowledge - mātauranga - is discussed and passed on) and other reflective practices, engaging with and led by mana whenua (guardians of the land) providing a thread which will guide the construction of the photographic images. The research fuses wānanga, that is Mātauranga Māori (Māori Knowledge), and photography practice in novel ways, aiming to move away and challenge core photographic conventions and Eurocentric modes of place representation. Roa and Hill understand wānanga as a fluid practice of engagement which can be with mana whenua or with the taiao - the environment - either by itself or with the mana whenua. This is the essence of Kaupapa Māori Research.
