House, home and dwellings - in an Australian context

Theoretical evidence in the behavioural and social sciences has shown the home to be a phenomenon borne of the complex relationship between individuals and their environment. A qualitative assessment of the specific home experiences of 12 case studies is offered to establish an understanding of home within a particular socio-cultural context in Australia. The thesis contends that the affective home has primacy in the home experience.

Occupant interaction with interior environment in Greek dwellings during summer

User behaviour significantly affects energy consumption simulation estimates, which can consequently influence architectural design decisions at an early stage. Different regional behavioural patterns could, therefore, hinder the applicability of certain architectural and environmental strategies. Through questionnaires analysis and field studies, this study investigates the pattern use of manual control of windows, shading and air condition units, in residential buildings in Greece, during summer. Initial findings of the analysis indicate significant interaction of Greek residents with the building shell, in their effort to maintain comfort.

Revealing Australia’s Underground Economy

This study, using currency demand model, finds Australia’s underground economy to be around 2 to 3 per cent of gross domestic product. We extend the related literature (see, inter alia, Bajada, 1999 and Breusch, 2005) in three novel ways. First, we use Austrian levels of taxes and welfare payments as the minimum levels of taxes and welfare payments. Secondly, we employ the currency demand measurement as in Cagan (1958), i.e., cash and currencies as a proportion of total money supply. Third, we use Cagan’s original assumption regarding equalities of velocities of currencies in both the legal and illegal economies in order to estimate the underground economy.

Simultaneous pattern and size optimisation of rock bolts for underground excavations

Designing a rock bolt reinforcement system for underground excavation involves determining bolt pattern, spacing, and size. In this paper, a topology optimisation technique is presented and employed to simultaneously optimise these design variables. To improve rock bolt design, the proposed technique minimises a displacement based function around the opening after bolt installation. This optimisation technique is independent of the material model and can be easily applied to any material model for rock and bolts. It is also extremely flexible in that it can be applied to any mechanical analysis method. To illustrate the capabilities of this method, numerical examples with non-linear material models and discontinuities in the host rock are presented. It is shown that the complexity of systems optimised using this approach is only restricted by limitations of the method used to analyse mechanical system responses.

A study on truss bolt mechanism in controlling stability of underground excavation and cutter roof failure

The truss bolt reinforcement system has been used in controlling the stability of underground excavations in severe ground conditions and cutter roof failure in layered rocks especially in coal mines. In spite of good application reports, working mechanism of this system is largely unknown and truss bolts are predominantly designed based on past experience and engineering judgement. In this study, the reinforcing effect of the truss bolt system on an underground excavation in layered rock is studied using non-linear finite element analysis. Different indicators are defined to evaluate the reinforcing effects of the truss bolt system. Using these indicators one can evaluate the effects of a reinforcing system on the deformation, loosened area, failure prevention, horizontal movement of the immediate layer, shear crack propagation and cutter roof failure of underground excavations. Effects of truss bolt on these indicators reveal the working mechanism of the truss bolt system. To illustrate the application of these indicators, a comparative study is conducted between three different truss bolt designs. It is shown that the design parameters of truss bolt systems, including tie-rod span, length, and angle of the bolts can have significant effects on the reinforcing capability of the system.

Style wars: revolution in the suburbs?

Is there a revolution occurring in the Australian suburb? From a brief examination of demographic, economic, political and aesthetic changes, it appears that the suburbs of the new century are very different from those of the last. With the demise of key underpinnings of the older suburban form—the sexual division of labour, particular family forms, localised communities and bucolic private gardens—has gone an end to official support of the expansive suburb and a major shift in their politics, planning, economies and relationship to the CBD and other centres. With falling household sizes has gone a seemingly contradictory trend toward larger houses on smaller blocks of land. In the context of these many changes along with urban containment and consolidation, this paper argues that there is a convergence occurring between the design of inner, middle and outer suburban dwellings. The negativity long heaped upon the suburban bungalow by the custodians of taste is being revisited. The style wars are easing, as suburban homes increasingly resemble those appearing in densified cities across the nation.

A range of factors influencing Sydney dwelling sale prices

This paper presents findings from an evaluation of a range of factors considered to influence dwelling sale prices in Sydney. The aim is to determine whether factors such as dwelling type, location, population structure and sales transaction type. significantly influence dwelling sale prices in Sydney. A review of the local market literature reveals that this belief has not been validated in the recent times. Hence, some of these factors may be inadequately exploited by dwelling investors. A sample of 33 dwelling Units from eight randomly selected suburbs located within 20kms of the Sydney Central Business District (CBD) was studied, and data analysed using simple Pearson's correlation. Significant associations were only found between Australian-born population proportion and dwelling type, and the sale prices. Hence, within the scope and methodology limitations. This paper concludes that, while dwelling type and Australian-born population proportion of a suburb are significantly associated with dwelling sale prices, location. population density and sales transaction type, are virtually not, as earlier held. The implication is for the amount of effort expended on location models, sales transaction marketing and population size studies. to be reviewed, at least, in relation to dwellings. This message resonates to cities and locations of similar characteristics as Sydney.

In the realm of the hackers

In the late 1980s, Melbourne was the hub of the computer underground in Australia, if not the world. The hackers who formed the underground were not disgruntled computer professionals or gangs of organised criminals. They were disaffected teenagers who used their basic home computers to explore the embryonic Internet from inside their locked, suburban bedrooms. From this shadowy world emerged two elite hackers known as Electron and Phoenix, who formed part of an alliance called The Realm. In the Realm of the Hackers charts Electron's journey from his initial innocent explorations to his ultimate obsession. It vividly recreates the climate of the 1980s, before there was public access to the Internet. The program takes us headlong into the clandestine, risky but intoxicating world of the computer underground to uncover not only how the hackers did it but why.

A new paradigm for sustainable residential buildings

This paper explores a new paradigm in housing, where dwellings will be pre-fabricated, modular, energy efficient, transportable and use renewable and/or recyclable resources. The paper reviews previous attempts to produce housing, which meets some of the criteria for this new paradigm. Their advantages and disadvantages are discussed. An approach towards a new type of modular prefabricated unit is proposed. A preliminary energy analysis, comparing a present relocatable classroom construction with one upgraded, is provided as an example towards low energy building operation. Finally, conclusions are drawn about the requirements of future housing if we are to progress towards sustainability.
