No full textThe next government has a primary requirement to be well briefed on the challenges inherent in Australia’s strategic circumstances and the policy options available to it. ASPI is publishing this report to layout our strategic choices and to provide recommendations.
Contributors are Peter Jennings on strategic policy, Mark Thomson and Andrew Davies on defence, Anthony Bergin and Kristy Bryden on homeland security, Russell Trood on foreign policy and Ryan Stokes on economic security.
This body of ideas makes a compelling contribution to the discussions which ought always to characterise the Australian strategic and defence debate
An incomplete project: Graphic adaptations of Moby-Dick and the ethics of response
No full textThe chapter, "An incomplete project: Graphic adaptations of Moby-Dick and the ethics of response" was written by Peter Wilkins (Douglas College Faculty). A cross-disciplinary collection of essays in the fields of nineteenth-century history, adaptation, word/image and Victorianism. Featuring new writing by some of the most influential, respected and radical scholars in these fields, Transforming Anthony Trollope constitutes both a close companion to Simon Grennan’s 2015 graphic novel Dispossession – an adaptation of Anthony Trollope’s 1879 novel John Caldigate – and a forward-looking, stand-alone addition to current debates on the cultural uses of history and the theorisation of remediation, illustration and narrative drawing. -- Back cover.

On numerics and inverse problems
No full textThesis (Ph.D.)--University of Washington, 2015In this thesis, two projects in inverse problems are described. The first concerns a simple mathematical model of synthetic aperture radar with undirected beam, modeled as a 2D circular Radon transform with centers restricted to a plane curve \gamma. From the work of Stefanov and Uhlmann (2013), it is known that this operator is microlocally non-injective locally, but microlocally injective globally if \gamma is closed. The problem for non-closed \gamma is examined; it is shown that the Radon transform R_\gamma is microlocally non-injective to leading order if a certain geometric condition is satisfied. Known examples where this condition holds are given. Numerical simulations demonstrate R_\gamma's microlocal non-injectivity for a single curve, and for a four-curve setup satisfying the geometric condition. The second project involves the implementation of an algorithm by de Hoop, Uhlmann, Vasy, and Wendt (2013), with refinements, for computing generic Fourier integral operators (FIOs) associated with canonical graphs, possibly involving caustics. The algorithm can be divided into two parts: a local component that approximately evaluates an FIO A: C^\infty_0(X)\to \mathcal D'(Y) expressed in the oscillatory integral form Af(y)=\int e^{i\phi(y,\xi)} a(y,\xi)\,\hat f(\xi)\,d\xi, modulo an error operator of order 1/2 less than the order of A, and a global component that expresses an arbitrary FIO associated with a canonical graph as a finite sum of these local oscillatory integrals composed with appropriate coordinate changes. A numerical implementation of their algorithm is demonstrated and successfully applied to a variety of FIOs associated with canonical graphs. This algorithm is designed to be easy-to-use for future researchers and the code is freely available from the author

Young Anthony van Dyck revisited : a multidisciplinary approach to a portrait once attributed to Peter Paul Rubens
No full textAbstract: Part of the collection of the Rubens House in Antwerp is a portrait of young Anthony van Dyck, alternatively attributed to Peter Paul Rubens and his pupil Anthony van Dyck. In order to reconstruct the genesis of the portrait in a manner that improves upon past investigations, a number of high-end technological methods, such as X-radiography, X-ray computer tomography, mammographic tomosynthesis and macroscopic X-ray fluorescence, have been employed to render the overpainted layers visible again. The results of the interdisciplinary examinations of the portrait of the youthful Van Dyck are impressive. The combined results allow the later additions to be peeled away until the original composition can be reached. Several pentimenti are easily discernible and refer to a rather immature hand that makes the authorship of Peter Paul Rubens very unlikely. What emerges is a portrait of an ambitious young man with a luxuriant head of hair and a slightly turned-up collar. The hat and cape were added later. The facial features are more recognisable and the execution of the bold curls points irrefutably in the direction of Anthony van Dyck as the author of his own portrait
Music in words : the music of Anthony Burgess, and the role of music in his literature
No full textTheý principal focus of the thesis is Anthony Burgess, a prolific novelist whose first and
enduring creative passion was music in general and composition in particular. Burgess
criticism is limited and largely out-of-date, showing little recognition of the aural or musical
elements in his fiction, and virtually no specialist commentary on the music and its
relationships with the literature. The main aim of the thesis, therefore, is to demonstrate the
variety and strength of the widespread musical elements in Burgess's literature, including the
importance he attaches to the sonic basis of language, and to show that these are supported by
the musical sensibility and technical competence evident in his. compositions. It is suggested
that in the inevitable reassessmenot f his work following his death in 1993, the effects of his
musicianship on his literary work should play a greater part than hitherto, and the thesis makes
a contribution to this reassessmenbt oth through its original critical commentaries on his music
and through the music-orientated discussion of his literature.
After an introduction and literature review, the first chapter examines three examples of
Burgess's little-known music. All are associated with verbal texts, though the range is
otherwise wide, and through them it is possible to draw conclusions about the competence of
his handling of musical language and structure. The second and third chapters examine the
more familiar work of Burgess the acclaimed author, but from the unfamiliar viewpoint of its
musical content, including not only surface references but also hidden allusions and technical
puzzles aimed at the musician reader. Two instances of music serving as a structural template
for literature are analysed in detail, and attention is also drawn to Burgess's awareness of
musical elements in the content and language of the, work of some. of his predecessors. The
final core-chapter,e xamines the fusion of Burgess's literary and,m usical skills in the context of
his music and words for stage and radio.
What emerges is the clear intermeshing of his parallel careers;, and the production within his
distinctive literary output of work which, due to the radical extent of its musicalisation, has to
be viewed as musically-aware literature for specialised readers, at times evincing, it is
proposed, a logic which springs primarily from music
Wireless communication and localization systems under spatial and temporal channel variations
No full textThis electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Thesis: Ph. D., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2019Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 209-218).Wireless signals inevitably vary in time and space. The three chapters of this dissertation revolve around the exploitation of signal variations. This line of work has yielded new link-layer protocols for rateless codes on half-duplex additive white Gaussian noise channels; a new abstraction for short-range mobile-to-mobile and mobile-to-infrastructure "room-area" networks that adhere to the spatial boundaries of human conversation; a reduced-complexity tone reservation algorithm for optimizing signals to avoid amplifier non-linearities; and new tools for the study of physical-layer privacy and anonymity in wireless systems.by Peter Anthony Iannucci.Ph.

Vivaldi's Four Seasons and the Globalization of Musical Taste
No full text"Vivaldi's Four Seasons, or at least parts of it, can be recognised by enormous numbers of people on this planet, and its sounds seem to come from almost every elevator shaft, mobile phone, restaurant and television advert in the world. It stands as the very epitome of a globalized artwork, and therefore it would be reasonable to suppose that globalization theories would be a great help in explaining its success. That this may not be the case is one of the main points of this paper -�� but before we get to that, there are two matters that have to be set in place. The first is to define the characteristics of the Four Seasons as a global commodity (note that I refer to it in the singular, since the four individual pieces come as a package); the second is to describe the main tenets of globalization theories and some of their chief generating ideas. Trying to map the characteristics of the work onto the assertions of the theories will be the main business of this paper, and this process is designed not only to illuminate the work, but also to test the theories."

Integrating spinal codes into wireless systems
No full textThesis (S.M.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2013.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (p. 85-88).Rateless spinal codes [47] promise performance gains for future wireless systems. These gains can be realized in the form of higher data rates, longer operational ranges, reduced power consumption, and greater reliability. This is due in part to the manner in which rateless codes exploit the instantaneous characteristics of the wireless medium, including unpredictable fluctuations. By contrast, traditional rated codes can accommodate variability only by making overly conservative assumptions. Before spinal codes reach practical deployment, they must be integrated into the networking stacks of real devices, and they must be instantiated in compact, ecient silicon. This thesis addresses fundamental challenges in each of these two areas, covering a body of work reported in previous publications by this author and others [27, 26]. On the networking side, this thesis explores a rateless analogue of link-layer retransmission schemes, capturing the idea of rate adaptation and generalizing the approach of hybrid ARQ/incremental redundancy systems such as LTE [29]. On the silicon side, this thesis presents the development of a VLSI architecture that exploits the inherent parallelism of the spinal decoder.by Peter Anthony Iannucci.S.M
