Redesigning the Scajaquada Expressway

The Scajaquada Expressway was constructed in the early 1960’s and is now at the end of its functional life. The redesign and rebuilding of the roadway offers the opportunity to make it less dangerous and more compatible with the natural, historic, and cultural fabric of the parks, parkways, neighborhoods, schools, colleges, and museums it serves and impacts

Mangroves, garbage, fishing: Bringing everyday ecology to Sydney's industrial Georges River

Post war problems of rising urban, industrial pollution and intractable waste disposal are usually considered as technical and economic problems only, solutions to which were led by experts at State level, and filtered into Australia from the ferments occurring in the United States and Britain in the 1960s and 70s. This paper investigates the change which arose from the localities in which the impact of those effects of modern city development were occurring. In particular, this study looks at a working class, industrial area, the Georges River near Bankstown Municipality, which was severely affected by Sydneys post-war expansion. Here, action to address urgent environmental problems was initiated first at the local level, and only later were professional engineers and public health officials involved in seeking remedies. It was even later that these local experts turned from engineering strategies to environmental science, embracing the newly developed ecological analyses to craft changing approaches to local problems. This paper centres on the perspective of one local public health surveyor, employed by a local municipal council to oversee waste disposal, to identify the motives for his decisions to intervene dramatically in river health and waste disposal programs. Rather than being prompted to act by influences from higher political levels or overseas, this officer drew his motivation from careful local data collection, from local political agitation and from his own recreational knowledge of the river. It was his involvement with the living environments of the area the ways in which he knew the river - through personal and recreational experiences, which prompted him to seek out the new science and investigate emerging waste disposal technologies

Waterborne: Vietnamese Australians and river environments in Vietnam and Sydney

Vietnamese Australians who arrived in Australia as refugees since the 1970s and later as migrants, have developed complex relationships of remembering, knowing and belonging to environments in Vietnam and Sydney. Water was a frequent point of reference in our interviews with Vietnamese people in Sydney, and their relationships with water are used in this article to explore interviewees associations with places. The article focuses on cultural knowledge of environments, which people bring with them, such as their connections with rivers and oceans, central to both memories of place and the histories of Vietnam. These memories also change with return visits and experiences between these places. Vietnamese refugees experiences of escape and trauma coming across oceans from Vietnam also influence subsequent relationships with place. Finally, relationships with Sydney parks and urban waterways are explored by examining popular places for family and community get-togethers along Georges River, located near where many Sydney Vietnamese people live. These have become key places in making Sydney home for Vietnamese people. The article considers how Vietnamese Australian cultural knowledge of place could be shared and acknowledged by park managers and used in park interpretati

Principles of Discrete Time Mechanics: IV. The Dirac Equation, Particles and Oscillons

We apply the principles of discrete time mechanics discussed in earlier papers to the first and second quantised Dirac equation. We use the Schwinger action principle to find the anticommutation relations of the Dirac field and of the particle creation operators in the theory. We find new solutions to the discrete time Dirac equation, referred to as oscillons on account of their extraordinary behaviour. Their principal characteristic is that they oscillate with a period twice that of the fundamental time interval T of our theory. Although these solutions can be associated with definite charge, linear momentum and spin, such objects should not be observable as particles in the continuous time limit. We find that for non-zero T they correspond to states with negative squared norm in Hilbert space. However they are an integral part of the discrete time Dirac field and should play a role in particle interactions analogous to the role of longitudinal photons in conventional quantum electrodynamics.Comment: 27 pages LateX; published versio

Robust direction of arrival estimation in non-Gaussian noise

Cataloged from PDF version of article.In this correspondence, a nonlinearly weighted least-squares method is developed for robust modeling of sensor array data. Weighting functions for various observation noise scenarios are determined using maximum likelihood estimation theory. Computational complexity of the new method is comparable with the standard least-squares estimation procedures. Simulation examples of direction-of-arrival estimation are presented

Waterborne: Vietnamese Australians and Sydney's Georges River parks and green spaces

Waterborne: Vietnamese Australians and Sydney's Georges River parks and green spaces, has been created by talking with the Vietnamese Australians who live around the Georges River and who often visit its parklands. They explain here their memories of their early homelands, which are given a context with information about the histories of rivers and parks in Vietnam. Then these Vietnamese Australians talk about their hopes about parks in Australia and their actual experiences in the parks and rivers around their new homes near the Georges River
