Research outputs 2022 to 2026

It is well known that the mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si are closely related to its microstructure and texture. In this work, a novel treatment of electroshocking treatment (EST) was adopted to optimize the microstructure and improve the mechanical properties of this titanium alloy. The grain orientation, texture, and mechanical properties of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si alloy under EST were characterized and analyzed. With the increase of EST time to 0.04 s, the resultant acicular secondary αs shows a tendency of spheroidization and the increase in grain diameter, which leads to a little decrease in hardness and yield strength. The increase in EST time …

Modulation Recognition Of Low-Snr Uav Radar Signals Based On Bispectral Slices And Ga-Bp Neural Network, Xuemin Liu, Yaoliang Song, Kuiyu Chen, Shihao Yan, Si Chen, Baihua Shi

Research outputs 2022 to 2026

In this paper, we address the challenge of low recognition rates in existing methods for radar signals from unmanned aerial vehicles (UAV) with low signal-to-noise ratios (SNRs). To overcome this challenge, we propose the utilization of the bispectral slice approach for accurate recognition of complex UAV radar signals. Our approach involves extracting the bispectral diagonal slice and the maximum bispectral amplitude horizontal slice from the bispectrum amplitude spectrum of the received UAV radar signal. These slices serve as the basis for subsequent identification by calculating characteristic parameters such as convexity, box dimension, and sparseness. To accomplish the recognition task, we …

On The Stability Of Rubble Mound Structures Under Oblique Wave Attack, Meysam Bali, Amir Etemad-Shahidi, Marcel R. A. Van Gent

Research outputs 2022 to 2026

Slope stability formulae for rubble mound structures are usually developed for head-on conditions. Often, the effects of oblique waves are neglected, mainly because it is assumed that for oblique wave attack, the reduction in damage compared to perpendicular wave attack is insignificant. When the incident waves are oblique, the required armour size can be reduced compared to the perpendicular wave attack case. Therefore, it is important to consider the wave obliquity influence on slope stability formulae as a reduction factor. One of the most recent formulae for estimating the stability of rock-armoured slopes, referred to as Etemad-Shahidi et al. (2020), …

Digital Media, Ageing And Faith: Older Sri Lankan Migrants In Australia And Their Digital Articulations Of Transnational Religion, Shashini Gamage, Raelene Wilding, Loretta Baldassar

Research outputs 2022 to 2026

To date, older adults have received little attention in the newly emerging technological narratives of transnational religion. This is surprising, given the strong association of later life with spiritual and religious engagement, but it likely reflects the ongoing assumption that older adults are technophobic or technologically incompetent. Drawing on ethnographic interviews with older Sinhalese Buddhist migrants from Sri Lanka, living in Melbourne, this paper explores the digital articulations of transnational religion that arise from older migrants’ uses of digital media. We focus on how engagements with digital media enable older Sinhalese to respond to an urgent need to accumulate merit …

Mechanisms Of Theta Burst Transcranial Ultrasound Induced Plasticity In The Human Motor Cortex, Yazan Shamli Oghli, Talyta Grippe, Tarun Arora, Tasnuva Hoque, Ghazaleh Darmani, Robert Chen

Department of Medicine Faculty Papers

BACKGROUND: Transcranial ultrasound stimulation (TUS) is a novel non-invasive brain stimulation technique with high depth penetrance and spatial resolution. Theta-burst TUS (tbTUS) is a plasticity-inducing protocol which increases motor cortical excitability for up to 30 min following 80s of sonication. While this protocol may have therapeutic potential for the treatment of psychiatric and neurological disorders, the mechanisms of action of TUS remain unclear.

OBJECTIVE: We conducted the first pharmacological study to examine the mechanisms of TUS in human primary motor cortex. By administering brain-active drugs with known mechanisms of action, we aimed to elucidate the mechanisms of tbTUS.

METHODS: Fourteen …
