The Impact On The Gold Coast's Terrestrial Environments, Tor Hundloe
The Impact On The Gold Coast's Terrestrial Environments, Tor Hundloe
Tor Hundloe
Extract: We tend to think of the Gold Coast as a water environment. As tourists know, it sits on the shore of the vast Pacific Ocean. That is why most come. They have seen the magnificent photographs. If not perched on flattened dunes looking east to the ocean, a significant part of the urban Gold Coast environment is located around natural and human-made water environments. Of these we will say little here, other than to note their extent. The focus of this chapter is the city's terrestrial environments, reporting on and ultimately, after describing the environments, discussing what proportion of …
Measuring Good Architecture: Long Life, Loose Fit, Low Energy, Craig Langston
Measuring Good Architecture: Long Life, Loose Fit, Low Energy, Craig Langston
Craig Langston
Good architecture is something that we all seek, but which is difficult to define. Sir Alexander John Gordon, in his role as President of the Royal Institute of British Architects, defined ‘good architecture’ in 1972 as buildings that exhibit ‘long life, loose fit and low energy’. These characteristics, nicknamed by Gordon as the 3L Principle, are measurable. Furthermore, life cycle cost (LCC) provides a method for accessing the economic contribution or burden created by buildings to the society they aim to serve. Yet there is no research available to investigate the connection, if any, between 3L and LCC. It might …
Designing For Better Building Adaptability: A Comparison Of Adaptstar And Arp Models, Sheila Conejos, Craig Langston, Jim Smith
Designing For Better Building Adaptability: A Comparison Of Adaptstar And Arp Models, Sheila Conejos, Craig Langston, Jim Smith
Craig Langston
Can sustainability and adaptability be integrated in a single decision tool for designing future buildings? Indeed, it is not possible to know what lies ahead for future buildings but, using current research on sustainability and the impact on natural resources and climate, it is possible to forecast the connection between built environment activity and sustainability. This paper demonstrates that the assessment of future adaptation in newly designed building is achievable by using the adaptSTAR model. This new design-rating tool, based on detailed analysis of 12 award-winning adaptive reuse projects in Australia, will assist designers in making decisions to achieve optimum …

Soil Chemistry: Understanding Phosphorus In The Environment, Paul Milham, Warwick Dougherty, Robert Morrison, Robert Clark, Ronald Smernik, Ashlea Doolette, Lucy Burkitt, Damian Collins, Rebeca Alvarez, Andrew Thomas
Robert Clark
It is an essential ingredient in food production, but poor management means bad news downstream. Understanding the way phosphorus behaves in the environment calls for soil and plant biology, and some new soil chemistry.
Single-Grain Osl Chronologies For Middle Palaeolithic Deposits At El Mnasra And El Harhoura 2, Morocco: Implications For Late Pleistocene Human-Environment Interactions Along The Atlantic Coast Of Northwest Africa, Zenobia Jacobs, Richard Roberts, Roland Nespoulet, M El Hajraoui, Andre Debenath
Single-Grain Osl Chronologies For Middle Palaeolithic Deposits At El Mnasra And El Harhoura 2, Morocco: Implications For Late Pleistocene Human-Environment Interactions Along The Atlantic Coast Of Northwest Africa, Zenobia Jacobs, Richard Roberts, Roland Nespoulet, M El Hajraoui, Andre Debenath
Richard G Roberts
Optically stimulated luminescence (OSL) measurements were made on individual, sand-sized grains of quartz from Middle Palaeolithic deposits at two cave sites (El Harhoura 2 and El Mnasra) on the Atlantic coast of Morocco. We were able to calculate OSL ages for 32 of the 33 samples collected from the Middle Palaeolithic deposits, including the earliest and latest Aterian levels at both sites. These ages reveal periods of occupation between about 110 and 95 ka (thousands of years ago), and at ~75 ka. A late Middle Palaeolithic occupation of El Harhoura 2 is also recorded at ~55 ka. Our single-grain OSL …

Joint Modeling Of Additive And Non-Additive (Genetic Line) Effects In Multi-Environment Trials, H Oakey, A Verbyla, Brian Cullis, X. Wei, W. Pitchford
Joint Modeling Of Additive And Non-Additive (Genetic Line) Effects In Multi-Environment Trials, H Oakey, A Verbyla, Brian Cullis, X. Wei, W. Pitchford
Professor Brian Cullis
A statistical approach for the analysis of multienvironment trials (METs) is presented, in which selection of best performing lines, best parents, and best combination of parents can be determined. The genetic effect of a line is partitioned into additive, dominance and residual nonadditive effects. The dominance effects are estimated through the incorporation of the dominance relationship matrix, which is presented under varying levels of inbreeding. A computationally efficient way of fitting dominance effects is presented which partitions dominance effects into between family dominance and within family dominance line effects. The overall approach is applicable to inbred lines, hybrid lines and …
A Networked Virtual Environment Communications Model Using Priority Updating, Yang-Wai Chow, Ronald Pose, Matthew Regan
A Networked Virtual Environment Communications Model Using Priority Updating, Yang-Wai Chow, Ronald Pose, Matthew Regan
Dr Yang-Wai Chow
Networked virtual environments have been used in a variety of applications ranging from military training simulations to collaborative teleconferencing, and have recently become increasingly popular in the field of entertainment especially in online gaming. As the size, distribution and number of participants of these virtual world systems increases, so do the demands placed on the limited networking resources. This has presented networked virtual environment system developers with the problem of having to design efficient network communication models in order to reduce the amount of network traffic and bandwidth utilization, while at the same time not compromising on the real-time interactive …

Human-To-Robot Skill Transfer Through Haptic Rendered Environment, Yan Chen, Fazel Naghdy
Professor Fazel Naghdy
A new paradigm for programming of robotics manipulator is being studied. The teaching of the machine will begin with the necessary skills being demonstrated by the human operator in a virtual environment with tactile sensing (haptics). Position and contact force/torque data generated in the virtual environment combined with a priori knowledge about the task will be used to identify and learn the skills in the newly demonstrated tasks and then to reproduce them in the robotics system. The peg-in-hole insertion problem is used as a case study. The overall concept is described. The methodologies developed to build the virtual environment …
