Policy Challenges From The "White" Senate Inquiry Into Workplace-Related Health Impacts Of Toxic Dusts And Nanoparticles, Thomas A. Faunce, Haydn Walters, Trevor Williams, David Bryant, Martin Jennings, Bill Musk
Policy Challenges From The "White" Senate Inquiry Into Workplace-Related Health Impacts Of Toxic Dusts And Nanoparticles, Thomas A. Faunce, Haydn Walters, Trevor Williams, David Bryant, Martin Jennings, Bill Musk
Thomas A Faunce
On 22 June 2005 the Senate of the Commonwealth of Australia voted to establish an inquiry into workplace harm related to toxic dust and emerging technologies (including nanoparticles). The inquiry became known as the "White" Inquiry after Mr Richard White, a financially uncompensated sufferer of industrial sandblasting-induced lung disease who was instrumental in its establishment. The "White" Inquiry delivered its final report and recommendations on 31 May 2006. This paper examines whether these recommendations and their implementation may provide a unique opportunity not only to modernize relevant monitoring standards and processes, but related compensation systems for disease associated with workplace-related …

Crisp Solution Of A General Fuzzy Linear System, S. Abbasbandy, R. Ezzati
Saeid Abbasbandy
In this paper a method for solving a general fuzzy linear system with crisp solution is considered. We consider the method in special case when the elements of the coefficient matrix and the right hand side are trapezoidal fuzzy numbers. The method in detail is discussed and followed by theorem and illustrated by solving some examples.

Controlled Generation Of Hard And Easy Bayesian Networks: Impact On Maximal Clique Size In Tree Clustering, Ole J. Mengshoel, David C. Wilkins, Dan Roth
Controlled Generation Of Hard And Easy Bayesian Networks: Impact On Maximal Clique Size In Tree Clustering, Ole J. Mengshoel, David C. Wilkins, Dan Roth
Ole J Mengshoel
This article presents and analyzes algorithms that systematically generate random Bayesian networks of varying difficulty levels, with respect to inference using tree clustering. The results are relevant to research on efficient Bayesian network inference, such as computing a most probable explanation or belief updating, since they allow controlled experimentation to determine the impact of improvements to inference algorithms. The results are also relevant to research on machine learning of Bayesian networks, since they support controlled generation of a large number of data sets at a given difficulty level. Our generation algorithms, called BPART and MPART, support controlled but random construction …

Regression With Signals And Images As Predictors, Philip T. Reiss
Regression With Signals And Images As Predictors, Philip T. Reiss
Philip T. Reiss
Signal regression and image regression, in which the outcomes are scalars and the predictors are one-dimensional signals or multidimensional images, are of interest in many scientific fields. The principal statistical challenge is how to reduce the dimension of the predictors in what would otherwise be a severely ill-posed problem. A pair of novel methods, functional principal component regression (FPCR) and functional partial least squares (FPLS), combine two existing approaches to the dimension reduction problem: selection of most relevant components, as is done in ordinary principal component regression (PCR) and partial least squares (PLS), and restriction of the coefficient function to …

An Evaluation Of Decision Tree And Survival Analysis Techniques For Business Failure Prediction, Adrian Gepp
An Evaluation Of Decision Tree And Survival Analysis Techniques For Business Failure Prediction, Adrian Gepp
Adrian Gepp
Accurate business failure prediction models would be extremely valuable to many industry sectors, particularly in financial investment and lending. The potential value of such models has been recently emphasised by the extremely costly failure of high profile businesses in both Australia and overseas, such as HIH (Australia) and Enron (USA). Consequently, there has been a significant increase in interest in business failure prediction, from both industry and academia. Statistical models attempt to predict the failure or success of a business based on publicly available information about that business (or its industry and the overall economy), such as accounting ratios from …

Stressed Liquid-Crystal Optical Phased Array For Fast Tip-Tilt Wavefront Correction, Bin Wang, Guoqiang Zhang, Anatoliy Glushchenko, John L. West, Philip Bos, Paul F. Mcmanamon
Philip J. Bos
A liquid-crystal optical phased-array technology that uses stressed liquid crystals provides a new type of tip-tilt wavefront corrector. It demonstrates a very fast time response (10 kHz) and high beam-steering efficiency (similar to 91%). The new technology presented here will allow for a nonmechanical, high-speed correction with simple device construction.
Self Consistent Bathymetric Mapping Using Sub-Maps: Survey Results From The Tag Hydrothermal Structure, C. Roman, R. Reves-Sohn, H. Singh, S. Humphris
Self Consistent Bathymetric Mapping Using Sub-Maps: Survey Results From The Tag Hydrothermal Structure, C. Roman, R. Reves-Sohn, H. Singh, S. Humphris
Christopher N. Roman
The spatial resolution of microbathymetry maps created using robotic vehicles such as ROVs, AUVs and manned submersibles in the deep ocean is currently limited by the accuracy of the vehicle navigation data. Errors in the vehicle position estimate commonly exceed the ranging errors of the acoustic mapping sensor itself, which creates inconsistency in the map making process and produces artifacts that lower resolution and distort map integrity. We present a methodology for producing self-consistent maps and improving vehicle position estimation by exploiting accurate local navigation and utilizing terrain relative measurements. The complete map is broken down into individual "sub-maps'', which …
Optimization Of Electrode Alignment For Electrochemical Detection In Capillary Electrophoresis Using A Scanning Electrochemical Microscope, David Roach, Stephanie Hooper, Mark Anderson
Optimization Of Electrode Alignment For Electrochemical Detection In Capillary Electrophoresis Using A Scanning Electrochemical Microscope, David Roach, Stephanie Hooper, Mark Anderson
Mark R. Anderson
Electrochemical detection in capillary electrophoresis requires decoupling the voltage applied to the working electrode from the separation voltage applied across the capillary. End-capillary electrochemical detection achieves this by placing the electrode just outside the ground end of the separation capillary. Obtaining adequate signal-to-noise in this arrangement requires using small inner diameter capillaries. Decreasing the inner diameter of the separation capillary, however, increases the difficulty of aligning the microelectrode with the open end of the capillary. Using scanning electrochemical microscopy (SECM), the position of the capillary opening is determined while electroactive material is continuously emerging from the end of the capillary. …

The Centrality Of Awareness In The Formation Of User Behavioral Intention Toward Preventive Technologies In The Context Of Voluntary Use, Tamara Dinev, Qing Hu
Qing Hu
Little is known about user behavior toward what we call preventive computer technologies that have become increasingly important in the networked economy and society to secure data and systems from viruses, unauthorized access, disruptions, spyware, and similar harmful technologies. We present the results of a study of user behavior toward preventive technologies based on the frameworks of theory of planned behavior in the context of anti-spyware technologies. We find that the user awareness of the issues and threats from harmful technologies is a strong predictor of user behavioral intention toward the use of preventive technologies. In the presence of awareness, …

Scaling Laws For Rotating Rayleigh-Bénard Convection, Janet Scheel, M. Cross
Scaling Laws For Rotating Rayleigh-Bénard Convection, Janet Scheel, M. Cross
Janet D. Scheel
Numerical simulations of large aspect ratio, three-dimensional rotating Rayleigh-Bénard convection for no-slip boundary conditions have been performed in both cylinders and periodic boxes. We have focused near the threshold for the supercritical bifurcation from the conducting state to a convecting state exhibiting domain chaos. A detailed analysis of these simulations has been carried out and is compared with experimental results, as well as predictions from multiple scale perturbation theory. We find that the time scaling law agrees with the theoretical prediction, which is in contradiction to experimental results. We also have looked at the scaling of defect lengths and defect …

High-Efficiency, Liquid-Crystal-Based, Controllable Diffraction Grating, Yanli Zhang, Bin Wang, Philip J. Bos, Jennifer Colegrove, David B. Chung
Philip J. Bos
We propose a new reflective liquid-crystal diffraction grating design attained by combining the use of a polymer wall to reduce the detrimental effect of the fringing electric field in a high-resolution grating and a quarterwave plate to make the device polarization independent. This design could offer significant performance advantages in a projection display system. Results of calculations are compared with experimental data. (c) 2005 Optical Society of America.
