Australia And The New Technologies: Towards Evidence Based Policy In Public Administration, K. Michael, M. G. Michael

Professor Katina Michael

This workshop addresses the application of evidence based policy in public administration. It specifically focuses on the issue of new technologies in the form of product and process innovations rolled out in Australia since major international events (e.g. Sept 11, Boxing Day Tsunami, Avian Flu outbreak). These product and process innovations introduced for the ‘common good’ are usually mandated by government agencies, designed and implemented by private business, and obligatorily adopted by citizens in the name of national security. The workshop investigates how information is gathered, processed and disseminated to provide evidence toward policy making. What qualitative and quantitative methods …

Investigation Of Stun Guns As Intentional Electromagnetic Interference (Emi) Sources, George H. Baker, Ryan C. Tuttle

George H Baker

Determined malefactors have demonstrated the use of common systems as effective weapons against civilian infrastructures, e.g. commercial jetliners used as kinetic weapons and cell phones used to trigger explosive devices. This undergraduate research project investigated the possibility of using readily available stun gun devices for electro-magnetic interference with or disruption of personal computers. At present, the system effects of high power electromagnetic sources are well recognized by world scientific and military communities. Former CIA Director John Deutch has said that, "the electron is the ultimate precision-guided weapon."1 There has been much research on the deleterious effects of pulsed voltages and …

Chiral Perturbation Theory: An Effective Field Theory, Br Holstein

Barry R Holstein

The concept of an effective field theory (EFT), i.e. a theory which is valid only in a limited range of parameter space, is one which has become highly developed recently. After presenting familiar examples from the realms of classical and quantum mechanics together with condensed matter physics, we show that QCD has an intriguing parallel with superconductivity in that, by using quark–antiquark (mesonic) degrees of freedom and exploiting the symmetries of the theory, a useful and powerful theory–chiral perturbation theory–results, which offers a complete and rigorous description of low energy particle and nuclear physics.

Bayesian Identification, Selection And Estimation Of Functions In High-Dimensional Additive Models, Anastasios Panagiotelis, Michael Smith

Michael Stanley Smith

In this paper we propose an approach to both estimate and select unknown smooth functions in an additive model with potentially many functions. Each function is written as a linear combination of basis terms, with coefficients regularized by a proper linearly constrained Gaussian prior. Given any potentially rank deficient prior precision matrix, we show how to derive linear constraints so that the corresponding effect is identified in the additive model. This allows for the use of a wide range of bases and precision matrices in priors for regularization. By introducing indicator variables, each constrained Gaussian prior is augmented with a …

On A = Mp Heronian Triangles And V = Ma Cones, John Hawkins, David Stone

John B. Hawkins

A determining all such triangles with area = m (perimeter). We also consider the analogous problem of finding cones with integer radius and height satisfying volume = m (total surface area). Recent activity and results on both problems have appeared recently in the School Science and Mathematics Problem Section and in the Mathematics Magazine, where our conjecture that the largest A = mP triangle is m2 +2, (4m2 +1)2,(16m4 +12m2) +1 was settled affirmatively.

Beam Dynamics In Pt Symmetric Optical Lattices, Konstantinos Makris, Ramy El-Ganainy, Demetrios Christodoulides, Z. Musslimani

Ramy El-Ganainy

The possibility of parity-time (PT) symmetric periodic potentials is investigated within the context of optics. Beam dynamics in this new type of optical structures is examined in detail for both one- and two- dimensional lattice geometries. It is shown that PT periodic structures can exhibit unique characteristics stemming from the nonorthogonality of the associated Floquet-Bloch modes. Some of these features include double refraction, power oscillations, and eigenfunction unfolding as well as nonreciprocal diffraction patterns.

Modeling Plasma Induced Dispersion In A Nonlinear Schrödinger Equation, Jeremy Gulley, William Dennis

Jeremy R. Gulley

Ultrafast laser pulse propagation in dielectrics is often modeled by a modified nonlinear Schrödinger equation (NLSE). At laser intensities sufficient to cause ionization, a plasma term can be included in the modified NLSE to account for free-carrier optical effects. This term is linear in the field and may be calculated from the classical Drude theory. We explore the consequences of a newly developed method for including dispersion relations of the plasma term as predicted by the Drude theory into the framework of the modified NLSE. The plasma induced dispersion terms can be shown to strongly effect ultrashort pulse evolution through …

Mobile Instructional Laboratory Environments And Their Use In Computing Sciences, Stefan Robila, Bert Wachsmuth, Christelle Scharff, Jeffrey Popyack

Bert Wachsmuth

The term 'mobile instructional laboratory' refers to using mobile computing devices such as notebooks for transforming a classroom into a lab setting with the goal of enhancing the practical experience, interaction and understanding. A major goal in all the computing disciplines is to provide students with hands on activities that will enhance their learning of concepts and their professional experience. As such, CS and IT programs require investments in dedicated laboratories that will support applied activities for most of the courses. Unfortunately, space and other resource limitations usually do not allow for permanent creation of such labs. In parallel, current …
