Low-cost autonomous 3-D monitoring systems for hydraulic engineering environments and applications with limited accuracy requirements

The details of developing autonomous 3-D motion monitoring systems based on commercial off-the-shelf (COTS) motion sensors for hydraulic environments are discussed. Possible areas of application, are river bed sediment transport monitoring and monitoring the agitation and other physical parameters inside milk vats with a mechanized agitator. Simplified calculations of inertial navigation systems (INSs) such as Euler angle method, MATLAB programs for further processing, power management systems for autonomous operation including the possibility of inductive power transfer (IPT) and use of microelectromechanical systems (MEMS) technology are discussed. Experimental results for proof of concept systems are highlighted

The Imperative Commands: the poetics of imperatives and assertions in everyday life

The Imperative Commands: the poetics of imperatives and assertions in everyday life. The Imperative Commands is an interdisciplinary creative writing PhD in two parts: (a) a poem-object of 365 pages, which is an original engagement with found everyday instructional language, reimagined in an experimental/visual format; (b) ‘Appropriate Language,’ a critical and theoretical afterword exploring the inspiration, themes and methods of the poem. The premise of The Imperative Commands is to investigate current institutional and corporate language and appropriate it as poetry. It is a collagistic arrangement of found imperatives and assertions, harvested from the language of state institutions and corporate bodies that hail people on a daily basis. To create this long poetic work I set myself the initial constraint of harvesting found language during the course of a calendar year (May 1st 2014 to 30th April 2015). During this time I collected found imperatives, assertions, naturalizations of contestable information as fact, and other forms of overt and tacit instruction. The material was then transcribed, organized and rearranged in a variety of forms, using both chance and editorial interventions to make deviant collocations, stochastic juxtapositions, concrete-visual constellations and lyrical expression. ‘Appropriate Language’ breaks into several forms of afterword. The introduction outlines the general architecture and aims behind The Imperative Commands, as well as key influences on my practice and what inspired the thesis. Its main purpose is to explore ideas around how society is manipulated by language and ideology by, and for, the various institutions that seek to influence us. To do this it focuses on the writing of two thinkers: (1) the so-called ‘father of public relations’ Edward Bernays (1891-1995), who was instrumental in developing PR in the 20th century; and (2) French philosopher Louis Althusser (1918-1990) and his theory of Ideological State Apparatuses—which form and inform the essential structure of society outside the state—and interpellation, whereby individuals become ‘subjects’ through the ways in which they are hailed by ISAs and ideology. The second purpose of ‘Appropriate Language’ is to consider the affinities and differences that The Imperative Commands has with Conceptual Writing, with a particular focus on the work and ideas of poet Kenneth Goldsmith (b. 1961). My research into Conceptual Writing, and its claims of unreadability, helped to remind me of the importance of readability that I feel about my own work. That the organization of the found texts should be a readable, though idiosyncratic, book is crucial to The Imperative Commands. The harvested material when reorganized to make the poem reveals aspects of the life of a subject during a specific period of time, with disparate facets of social control brought into focus through the various language forms that constitute everyday life. The poem-object, that is also a social document, explores ways of uniting the notion of ‘concept’ and experimental writing—particularly within some of the methodologies of Conceptual Writing—with ways of maintaining and supporting a ‘self’ that is both lyrical and political

A Genecological Study of the Widespread Australian Native Grass \u3ci\u3eAustrodanthonia Caespitosa\u3c/i\u3e (Gaudich.) H.P. Linder.

The lack of commercial quantities of seed is preventing the use of native grasses in large-scale revegetation programmes. Sourcing wild-land non-local provenance seed from distant locations brings with it risks associated with maladaptation and potential genetic pollution. Understanding of intra-specific ecotypic variation and its adaptive consequences is required to both increase seed supply and retain adaptive characteristics in native plant revegetation programmes. A recently commenced genecological study on the widespread Australian native grass, Austrodanthonia caespitose, aims to examine quantitative traits in a common garden study and genetic structure (using DNA analysis) of 35 populations collected from a large geographic range. Examination of the adaptive significance of these traits using reciprocal transplant experiments will aid in the development of provenance guidelines for Australian native grasses. In this paper we report the initial findings for one of many characteristics being measured in a common garden study, namely plant transpiration efficiency

Molecular phylogenetic evidence for ancient divergence of lizard taxa on either side of Wallace's Line

Wallace's Line, separating the terrestrial faunas of South East Asia from the Australia-New Guinea region, is the most prominent and well-studied biogeographical division in the world. Phylogenetically distinct subgroups of major animal and plant groups have been documented on either side of Wallace's Line since it was first proposed in 1859. Despite its importance, the temporal history of fragmentation across this line is virtually unknown and the geological foundation has rarely been discussed. Using molecular phylogenetics and dating techniques, we show that the split between taxa in the South East Asian and the Australian-New Guinean geological regions occurred during the Late Jurassic to Early Cretaceous in two independent lizard clades. This estimate is compatible with the hypothesis of rifting Gondwanan continental fragments during the Mesozoic and strongly rejects the hypothetical origin of various members of the Australian-New Guinean herpetofauna as relatively recent invasions from South East Asia. Our finding suggests an ancient fragmentation of lizard taxa on either side of Wallace's Line and provides further evidence that the composition of modern global communities has been significantly affected by rifting and accretion of Gondwanan continental plates during the Middle to Late Mesozoic

Lead exposure of mainland Australia\u27s top avian predator

Lead (Pb) toxicity, through ingestion of lead ammunition in carcasses, is a threat to scavenging birds worldwide, but has received little attention in Australia. We analyzed lead exposure in the wedge-tailed eagle (Aquila audax), the largest raptor species found in mainland Australia and a facultative scavenger. Eagle carcasses were collected opportunistically throughout south-eastern mainland Australia between 1996 and 2022. Lead concentrations were measured in bone samples from 62 animals via portable X-ray fluorescence (XRF). Lead was detected (concentration \u3e 1 ppm) in 84% (n = 52) of the bone samples. The mean lead concentration of birds in which lead was detected was 9.10 ppm (±SE 1.66). Bone lead concentrations were elevated (10–20 ppm) in 12.9% of samples, and severe ( \u3e 20 ppm) in 4.8% of samples. These proportions are moderately higher than equivalent data for the same species from the island of Tasmania, and are comparable to data from threatened eagle species from other continents. Lead exposure at these levels is likely to have negative impacts on wedge-tailed eagles at the level of the individual and perhaps at a population level. Our results suggest that studies of lead exposure in other Australian avian scavenger species are warranted
