A Range Error Reduction Technique For Positioning Applications In Sports, Adnan Waqar, Iftekhar Ahmad, Daryoush Habibi, Quoc V. Phung

Research outputs 2014 to 2021

In recent times, ultra-wideband (UWB)-based positioning systems have become popular in sport performance monitoring. UWB positioning system uses time of arrival to calculate the range data between devices (i.e. anchors, tags), and then use trilateration algorithms to estimate position coordinates. In practical applications, non-line-of-sight transmissions and multipath propagations lead to inaccurate range data and lower positioning accuracy. This paper introduces a range error minimisation algorithm to address this limitation of error in range data in UWB-based positioning system. The proposed solution analyses the range error for each anchor and sequentially reduces this error based on the distance between each anchor …

Positive Drug Stories: Possibilities For Agency And Positive Subjectivity For Harm Reduction, Liam B. Engel, Stephen J. Bright, Monica J. Barratt, Matthew M. Allen

Research outputs 2014 to 2021

People who use drugs understand drugs and drug use in ways that are often different to the way knowledge of drug use is constructed within the dominant medico-legal discourse. Their experiences are, more often than not, represented in negative ways within dominant discourse, a disconnect that can create adverse consequences for people who use drugs, through the production of stigma and shame leading to poor health and social outcomes. A key difference in how drugs are understood by people who use drugs is the capacity of the former to recognize positive aspects of drug use and create more agentic subjectivities …

© 2021 The Authors. Journal of School Health published by Wiley Periodicals LLC. on behalf of American School Health Association. BACKGROUND: In this study, we examined nutrition-related topics among adolescent students attending schools with different Indices of Community Socio-Educational Advantage (ICSEA). METHOD: Participating students (N = 206) from 5 schools in Western Australia completed a paper-based questionnaire on nutrition-related topics. Frequencies and independent chi-square tests were used to identify differences between sexes and school ICSEA. RESULTS: Of the participating students, 75% were interested in learning about 8 of 16 topics. We found statistically significant differences by sex (p < .01) for “Eating the right foods for preventing illness and disease,” “Eating the right food for being active” among girls, and “Reducing food waste” among boys. We also noted differences by school ICSEA. CONCLUSION: Acknowledging sex and socioeducational differences in teaching and learning may help teachers to engage adolescent students in nutrition education.

Short Word-Length Entering Compressive Sensing Domain: Improved Energy Efficiency In Wireless Sensor Networks, Nuha A. S. Alwan, Zahir M. Hussain

Research outputs 2014 to 2021

This work combines compressive sensing and short word-length techniques to achieve localization and target tracking in wireless sensor networks with energy-efficient communication between the network anchors and the fusion center. Gradient descent localization is performed using time-of-arrival (TOA) data which are indicative of the distance between anchors and the target thereby achieving range-based localization. The short word-length techniques considered are delta modulation and sigma-delta modulation. The energy efficiency is due to the reduction of the data volume transmitted from anchors to the fusion center by employing any of the two delta modulation variants with compressive sensing techniques. Delta modulation allows …
