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: Cross-Needle Analog Meter to Monitor Charge
Time for Lithium-Ion Single Cell

authors: Scott, Jonathan B.

abstract: This manuscript describes a novel cross-needle analogmeter whose scale reads out voltage, current, and time remaining to reach full charge. The design is inspired by cross-needle Standing Wave Ratio(SWR) meters that read forward and reverse power. Voltage is displayed on an offset-zero linear scale, and current on a logarithmic scale from 1 mA to 10 A. Thisleads to a wide range of perceptible charge times and pleasantcharge-time contour lines. The prototype is implemented on a single PCB using a cheap PIC micro controller. It is scaled formonitoring a single 18650 lithium cell charged by a small solarpanel. The Novel contribution of this paper is the use of a crossneedleanalog meter with a third scale to measure time remaining to fully charge a Lithium-Ion single cell battery.

title: A socio-demographic profile of Māori living in Australia

authors: Kukutai, Tahu

subjects: demography

abstract: This report provides a comprehensive demographic and socio-economic profile of the Māori population in Australia using data from the 2011 Australia Census of Population and Housing. The purpose is to provide an evidence base with which to inform future policy approaches with respect to Māori in Australia. It focuses on five key areas: 

Population size and composition; 
Identity and culture; 
Year of arrival and citizenship; 
Education and work; 
Lone parenting and unpaid childcare. 

Comparisons are undertaken with Māori in the 2006 Australia Census, as well as with two reference groups: the total Australia population and migrant non-Māori New Zealanders. Where appropriate, we also distinguish Māori migrants born in New Zealand and Māori born in Australia. This captures important differences within the Māori population in Australia that have been under-examined in previous studies.
