Experimental reintroduction of woody debris on the Williams River, NSW: geomorphic and ecological responses
No full textA total of 436 logs were used to create 20 engineered log jams (ELJs) in a 1.1 km reach of the Williams River, NSW, Australia, a gravel-bed river that has been desnagged and had most of its riparian vegetation removed over the last 200 years. The experiment was designed to test the effectiveness of reintroducing woody debris (WD) as a means of improving channel stability and recreating habitat diversity. The study assessed geomorphic and ecological responses to introducing woody habitat by comparing paired test and control reaches. Channel characteristics (e.g. bedforms, bars, texture) within test and control reaches were assessed before and after wood placement to quantify the morphological variability induced by the ELJs in the test reach. Since construction in September 2000, the ELJs have been subjected to five overtopping flows, three of which were larger than the mean annual flood. A high-resolution three-dimensional survey of both reaches was completed after major bed-mobilizing flows. Cumulative changes induced by consecutive floods were also assessed. After 12 months, the major geomorphologic changes in the test reach included an increase in pool and riffle area and pool depth; the addition of a pool-riffle sequence; an increase by 0.5-1 m in pool-riffle amplitude; a net gain of 40 m3 of sediment storage per 1000 m2 of channel area (while the control reach experienced a net loss of 15 m3/1000 m2 over the same period); and a substantial increase in the spatial complexity of bed-material distribution. Fish assemblages in the test reach showed an increase in species richness and abundance, and reduced temporal variability compared to the reference reach, suggesting that the changes in physical habitat were beneficial to fish at the reach scale
Putting the wood back into our rivers: an experiment in river rehabilitation
No full textThis paper presents an overview of a project established to assess the effectiveness of woody debris (WD) reintroduction as a river rehabilitation tool. An outline of an experiment is presented that aims to develop and assess the effectiveness of engineered log jams (ELJs) under Australian conditions, and to demonstrate the potential for using a range of ELJs to stabilise a previously de-snagged, high energy gravel-bed channel. Furthermore, the experiment will test the effectiveness of a reach based rehabilitation strategy to increase geomorphic variability and hence habitat diversity. While primarily focusing on the geomorphic and engineering aspects of the rehabilitation strategy, fish and freshwater mussel populations are also being monitored. The project is located within an 1100m reach of the Williams River, NSW. Twenty separate ELJ structures were constructed, incorporating a total of 430 logs placed without any artificial anchoring (e.g., no cabling or imported ballast). A geomorphic control reach was established 3.1 km upstream of the project reach. In the 6 months since the structures were built the study site has experienced 6 flows that have overtopped most structures, 3 of the flows were in excess of the mean annual flood, inundating 19 of the ELJs by 2 - 3 m, and one by 0.5 m. Early results indicate that with the exception of LS4 and LS5, all structures are performing as intended and that the geomorphic variability of the reach has substantially increased
JAB42: The 5-Alive Issue
No full textThis research output (JAB 41 & 43) builds on Mosely’s research portfolio “abbe 2017”. Mosely co-selected papers from abbe 2017 with Brad Freeman (founder and editor of the Journal of Artists’ Books /JAB) for volumes 41 & 43 of JAB. This outcome continues to address the call from scholars in the field to advance the critical nature of the field with a developing critical terminology and corresponding discourse.
Leading up to abbe 2017 Mosely published a short article/note in JAB 40 describing the research focus on artists books emerging at Queensland College of Art, “Inflections & ABBE 2017: Texturing GCCAR's Artists' Book Research Focus”. Abbe 2017 coalesced around Gilles Deleuze’s zweifalt, a fold that both identifies difference and at the same time holds those differences within a relationship. Following abbe 2017 Mosely co-ordinated the selection, peer reviewing and editing of academic papers from the event. In total 5 articles addressing the fold and studio practice, critical discourse and philosophical concerns were accepted by peer review for publication across two volumes of JAB. With an international readership and subscription base to hundreds of libraries and artists books collections around the globe these papers extend Australian artist’s & scholar’s contribution to artists book research in the emerging critical discourse.No Full Tex
JAB 39 The Australian JAB
No full textThis research output (JAB 39) builds on Mosely’s research portfolio “abbe 2015”, He co-edited this volume of The Journal of Artists Books drawing from academic papers delivered at abbe 2015. This outcome addresses the continuing call from scholars in the field to advance the critical nature of the field with a developing critical terminology and corresponding discourse.
A Keynote presenter at abbe 2015 was Brad Freeman, the founder and editor of the Journal of Artists’ Books (JAB) published in the USA. Leading up to abbe Mosely negotiated with Freeman to publish in JAB papers from abbe that represented an original contribution to the field. Following abbe 2015 Mosely co-ordinated the selection, peer reviewing and editing of academic papers from the event. In total 11 articles from the 14 academic papers presented were accepted by peer review for publication in the 39th volume of JAB, now termed “the Australian JAB”. Mosely was also invited by Freeman to produced a small artists book for the Australian JAB). The book he produced was a 48 page offset printed book that positions a range of terms taken from haptic aesthetics into artists book discourse. The book was printed by Brad Freeman, in full CMYK colour, at the Centre for Paper Book and Print, Columbia College Chicago, Chicago, USA. This centre is a leading contributor to the field of artists book discourse. As convenor for abbe Mosely wrote the introduction to the Australian JAB, “Notes on Artists Books from the Antipodes”, In this introduction he provided a basic description of the theoretical framework for the published papers, and the “research question” that shaped the proceeding of abbe 2015.
With an international readership and subscription base to hundreds of libraries and artists books collections around the globe this contribution to artists book research positions the haptic and post literacy as critical elements in the emerging artists book critical discourse.No Full Tex

Technological roadmap on AI planning and scheduling
No full textAt the beginning of the new century, Information Technologies had become basic and indispensable
constituents of the production and preparation processes for all kinds of goods and services and
with that are largely influencing both the working and private life of nearly every citizen. This
development will continue and even further grow with the continually increasing use of the Internet
in production, business, science, education, and everyday societal and private undertaking.
Recent years have shown, however, that a dramatic enhancement of software capabilities is required,
when aiming to continuously provide advanced and competitive products and services in all these
fast developing sectors. It includes the development of intelligent systems – systems that are more
autonomous, flexible, and robust than today’s conventional software.
Intelligent Planning and Scheduling is a key enabling technology for intelligent systems. It has
been developed and matured over the last three decades and has successfully been employed for a
variety of applications in commerce, industry, education, medicine, public transport, defense, and
government.
This document reviews the state-of-the-art in key application and technical areas of Intelligent Planning
and Scheduling. It identifies the most important research, development, and technology transfer
efforts required in the coming 3 to 10 years and shows the way forward to meet these challenges in
the short-, medium- and longer-term future.
The roadmap has been developed under the regime of PLANET – the European Network of Excellence
in AI Planning. This network, established by the European Commission in 1998, is the co-ordinating
framework for research, development, and technology transfer in the field of Intelligent Planning and
Scheduling in Europe.
A large number of people have contributed to this document including the members of PLANET non-
European international experts, and a number of independent expert peer reviewers. All of them are
acknowledged in a separate section of this document.
Intelligent Planning and Scheduling is a far-reaching technology. Accepting the challenges and progressing
along the directions pointed out in this roadmap will enable a new generation of intelligent
application systems in a wide variety of industrial, commercial, public, and private sectors
Active microstructured x-ray optical arrays
No full textThe UK Smart X-Ray Optics consortium is developing novel reflective adaptive/active x-ray optics for small-scale laboratory applications, including studies of radiation-induced damage to biological material. The optics work on the same principle as polycapillaries, using configured arrays of channels etched into thin silicon, such that each x-ray photon reflects at most once off a channel wall. Using two arrays in succession provides tow reflections and thus the Abbe sine condition can be approximately satisfied, reducing aberrations. Adaptivity is achieved by flexing one or both arrays using piezo actuation, which can provide further reduction of aberrations as well as controllable focal lengths. Modelling of such arrays for used on an x-ray microprobe, based on a microfocus source with an emitting region approximately 1 mu m in diameter, shows that a focused flux approximately two orders of magnitude greater than possible with a zone plate of comparable focal length is possible, assuming that the channel wall roughness is less than about 2nm
