Numerical Investigation Of The Influence Of Fiber Content On The Shear Performance Of Uhpc Deep Beams Reinforced With Hybrid Steel And Synthetic Fibers, Hossein Mirzaaghabeik, Sanjay Kumar Shukla, Nuha S. Mashaan

Research outputs 2022 to 2026

This study investigates the shear performance of ultra-high-performance concrete deep beams (UHPC-DBs) reinforced with hybrid fibers comprising 5D steel fibers and Forta-Ferro (FF) synthetic fibers. UHPC-DBs are widely used in bridges, piles, and transfer girders because of their high load-bearing capacity. Although fiber content strongly influences shear behavior, the contribution of synthetic fibers in hybrid systems remains insufficiently understood. To address this gap, finite element analysis based on the concrete damage plasticity (CDP) model was developed in ABAQUS and validated using experimental results from five previously tested UHPC-DBs with different fiber contents. Load–deflection response, crack patterns, shear capacity, mid-span deflection, …

Research outputs 2022 to 2026

This paper presents the Multi-Objective Reptile Search algorithm for identifying ideal rating and location of distributed generation in unbalanced grids, focusing on minimizing power losses, total costs, and carbon emissions. The proposed methodology integrates DIgSILENT PowerFactory and Python platforms to evaluate unbalanced IEEE distribution feeders under varying power factor conditions. The results demonstrate that optimal DG configurations involve strategically positioning multiple units to enable both active and reactive power injection, significantly improving overall system performance across multiple objectives and voltage deviation index. The analysis identifies an optimal PF range between 0.75 and 0.89, with unity power factor operations yielding suboptimal …

Precarity On The Move: The Relative Economic Precarity Of Mobile Youth Moving To Australia, Lara Mckenzie, Anita Harris, Loretta Baldassar

Research outputs 2022 to 2026

Analyses of precarity often focus on how insecure employment, careers, finances, and geographies influence people’s lives for the worse, with young people understood as especially precarious in their economic stability and transitions to adulthood. This article analyses accounts of precarity amongst middling transnationally mobile youth, drawing from 24 semi-structured interviews incoming to Australia, and longitudinal survey data. We show that experiences of economic precarity are impacted by their access to work, government support, ability to access or sustain visas, and access to support from family and partners. By drawing on migration scholars’ observations that transnational mobility can be privileged and …

A qualitative multi-method design examined eight university students (aged 18–24) at an Australian university through pre-post focus groups, observational field notes, and artefact analysis. Participants voluntarily engaged in workshops co-designing peer-focused social media prevention messaging. Inductive thematic analysis identified patterns …

Combined Effect Of Porosity And Pore-Size Heterogeneity On Young’S Modulus Of Chemically Corroded Rocks, Hao Li, Zhenjiang You, Leo Pel, David Smeulders

Research outputs 2022 to 2026

Young’s modulus is a critical parameter for evaluating the stability of rock reservoirs, such as CO₂ geological storage. These reservoirs are exposed to chemically corrosions, which alter the pore structure, particularly porosity and pore size heterogeneity, thereby affecting Young’s modulus. This study conducted multiscale experiments to investigate how acid-driven chemical corrosion affects pore structure and its relationship with the Young’s modulus of rocks. Nuclear Magnetic Resonance (NMR) was used to characterize pore structure evolution, while corrosion mechanisms were examined via mass loss, XRD, pH monitoring, and ion chromatography. Based on the experimental results, a Kinetic Weibull Modulus (KWM) model was …

Decoupling Sustainability And Performance: How Government Infrastructure Projects In Australia Fare On Strategic Environmental Commitments, Richard Hughes, Kerry Brown

Research outputs 2022 to 2026

Australian government organisations are pivotal in helping to meet the United Nations sustainable development goals. Yet while these organisations promote sustainability in their strategic plans, they struggle to embed these same commitments into their own infrastructure and construction projects. This study examines this persistent disconnect using the lens of strategic decoupling, which explains how organisations symbolically align with external expectations while internal practices remain unchanged. Using a two-stage qualitative design, we conducted a positivist discourse analysis of strategic artefacts from six government organisations and a theoretically informed interpretivist analysis of 30 interviews with project professionals, framed by strong structuration theory. …

From Flexibility To Friction: Intended And Unintended Consequences Of Hot-Desking In Workplaces, Cheuk Hang Au, Lin Yue, Siqi Gao, Guanglei Cheng

Research outputs 2022 to 2026

Purpose: This study aims to theorize the tensions of hot-desking. Moving beyond its surface-level effects, we explain its complex impact on employee well-being and organizational conflict.

Design/methodology/approach: Using a multi-platform netnographic approach, we analyzed unsolicited discussions from online communities to capture diverse, authentic experiences across Eastern and Western contexts.

Findings: Grounded in technology affordance and constraints theory (TACT), our central finding is that hot-desking's affordances and constraints are dynamically co-produced. The organizational affordance of space efficiency is directly experienced by employees as a constraint of spatial insecurity and resource deprivation. This core tension fuels emergent social conflicts, such as senior …

Multi-Scale Sensor-Aware Variational Autoencoders For Adaptive Iot Security: Integrating Drift Calibration And Cyberattack Detection, Md Kamal Hossain, Iftekhar Ahmad, Daryoush Habibi

Research outputs 2022 to 2026

Existing approaches to Industrial Internet of Things (IoT) anomaly detection treat sensor drift calibration and cyberattack detection as separate problems, overlooking their strong interdependence and the compound failure modes that arise when drift dynamics are exploited by stealthy adversaries. Industrial Internet of IoT sensor networks therefore require a unified framework that jointly models both phenomena. This paper proposes the first unified multi-scale sensor-aware variational autoencoder (MS-VAE) framework that jointly models sensor drift and malicious activity within shared latent representations, enabling integrated calibration and security monitoring. The framework introduces three key components: (i) a multi-scale latent architecture that captures short-term anomalies …

When Does The Peak Countermovement Jump Performance Occur? Mapping Peak-Trial Timing Across Six Clustered Repetitions, Karol Kruczek, Szymon Karpęcki, Tim Gabbett, Jason Lake, Michał Nowak

Research outputs 2022 to 2026

Force-plate countermovement jump (CMJ) testing is widely used to assess neuromuscular status, yet monitoring interpretation often relies on best-trial values from abbreviated protocols, potentially biasing conclusions when the session maximum occurs beyond the sampled attempts. We mapped peak-trial timing across a six-trial clustered (3 + 3) CMJ protocol for seven outcome and strategy force–time metrics, and tested whether this peak-trial pattern was preserved between personal best (PB) and typical state (TS) monitoring sessions, both defined using modified reactive strength index (mRSI) as the primary selection variable. Retrospective dual-force-plate data (1000 Hz; August 2020–December 2025) were analysed from 314 athletes who …

Enhancing Physical Performance With Ischemic Preconditioning: A Systematic Review And Meta-Analysis Of Moderators And Performance Outcomes, Yilin Zhang, Kai Xu, Hao Kong, Mingyue Yin, Chenghao Liu, Yun Xie, Liam Kilduff, Gustavo R. Mota, Olivier Girard

Research outputs 2022 to 2026

This study examined the effects of ischemic preconditioning (IPC) on physical performance, considering the influence of timing, warm-up (WU), participant characteristics, and IPC protocols structure. A total of 90 trials (1,439 participants) were retrieved from three databases and assessed using PICOS criteria. Multilevel meta-analyses with cluster-robust variance adjustments were conducted to calculate pooled effect sizes (Hedge’s g). Risk of bias and certainty of evidence were assessed using the RoB 2 tool and GRADE framework. IPC produced a trivial but significant improvement in physical performance (g = 0.13, P < 0.01), which persisted after excluding SHAM effects (g = 0.10; P < 0.01). Significant improvements were observed for maximum repetitions, time to failure, and power output, but not for jump ability, strength, or oxygen uptake. Comparable benefits were found for anaerobic (g = 0.15) and aerobic (g = 0.10) exercise, with greater effects in males and less-trained participants. Performance was further enhanced when IPC was followed by WU (g = 0.16), with the optimal IPC-to-WU interval being ~42 minutes. Without WU, the effective IPC window narrowed to 6–7 minutes. In practice, IPC can enhance physical performance, independently of sham effects, moderated by sex, training level, and WU. For competition or testing, the most effective strategy appears to be 3 or 4 × 5-min IPC protocol, followed by a 42-min interval, standardized warm-up, and endurance testing. For mechanistic studies, WU should be excluded, and testing conducted 6-7 minutes post-IPC. Future research should target women, middle-aged individuals, and elite athletes.

Super-Resolution Learning Inspired Spectral-Spatial Correlation Network For Hyperspectral Target Detection, Jiaping Zhong, Yunsong Li, Jianxin Li, Yanzi Shi, Weiying Xie, Paolo Gamba

Research outputs 2022 to 2026

Hyperspectral target detection (HTD) aims at extracting targets from complex backgrounds while overcoming noise interference. Existing deep learning models for HTD usually suffer from low spatial resolution and unitary representation, especially in space-borne platforms. Super-resolution, as a critical technology to enhance the spatial details, could effectively address the aforementioned issue. To make super-resolution absolutely pose positive effects on target detection, this paper proposes an end-to-end novel super-resolution learning inspired spectral-spatial correlation network for hyperspectral target detection (SR-HTD) from the perspective of spatial and spectral regularization to achieve high-precision detection. Specifically, we designed a Spatial Correlation Aggregation (SCA) module inspired by …

Refuelling Behaviour And Electric Vehicle Uptake: Evidence From A Behavioural Transition Framework In Western Australia, Navid Hashemi Taba, Khatavakhotan

Research outputs 2022 to 2026

This study examined how refuelling routines, price responsiveness and discount expectations relate to readiness to replace a conventional petrol vehicle with an electric vehicle in Western Australia. A structured survey of nonelectric vehicle owners was administered in Perth (n = 442; conventional petrol n = 408; hybrid n = 34). Protocol-based cleaning and distributional diagnostics guided nonparametric inference and segmentation. Refuelling frequency comparisons between conventional and hybrid vehicle owners indicated higher visit frequency and monthly consumption among the former (monthly consumption: median 150 L vs. 92 L; U = 6963.5, z = 4.48, p < 0.001), whereas within conventional vehicle owners, no significant association was observed between monthly consumption and stated willingness to adopt an electric vehicle (U = 6633.0, p = 0.671). Expected petrol price discounts were tightly centred (median 10%; interquartile range 5%–15%), yet cluster analysis revealed a distinct segment combining high discount expectations (≈22%) and higher monthly consumption (∼211 L). Correlation between consumption and discount expectations was negligible (r ≈ 0.03, p > 0.05). These findings suggest that adoption-related …
