Performance and Stall Margin Evaluation of Axial Slot Casing Treatment in a Transonic Multistage Compressor

Aerospace
Adverse pressure gradients are intrinsic to compressor flow behavior and are further intensified by secondary effects associated with rotor tip clearance flow interactions. Tip clearance generates leakage flow, which leads to the formation of tip leakage

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

Using Fine Sediment Monitoring to Quantify Sand Loading Over Time

River Research and Applications, EarlyView.
ABSTRACT Riverine sand loading can lead to geomorphic change, impacting river processes like lateral migration and vertical aggradation or degradation. Yet many sediment monitoring programs track only fine sediment measurable as total suspended solids (TSS). Here, we assess the ability for TSS data to be used to determine sand loading.

Breaking down seagrass fragmentation in a marine heatwave impacted World Heritage Area

Remote Sensing in Ecology and Conservation, EarlyView.
Habitat fragmentation can exacerbate the impacts of habitat loss but is rarely quantified in marine environments. Using satellite‐derived habitat maps, we identify widespread seagrass fragmentation following a marine heatwave that contributed to a dramatic shift in seascape structure in the Shark Bay World Heritage Area.

Integrated LEO Constellation and In‐Cabin Distribution System for Continuous Aircraft 5G Connectivity

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT The integration of low Earth orbit (LEO) satellite constellations with commercial aircraft communication systems presents critical challenges in maintaining continuous connectivity during dynamic flight conditions. Current geostationary satellite systems suffer from high round‐trip latency (>$$ > $$ 500 ms) and inadequate coverage at high ...

The Epistemic Generativity of Using a Model of a Big Idea

Science Education, EarlyView.
ABSTRACT Science instruction should involve learners in generating and warranting ideas, what we call epistemic generation. In modeling instruction, epistemic generation should be achieved by coordinating a model structure with the experienced world in reciprocal directions denoted as developing models and using models. In the former, a model structure

A Method for Assessing the Risks to Sustainability Posed by Process Operations

Sustainable Development, EarlyView.
ABSTRACT We present a framework for assessing the risks to sustainability posed by any given set of processes. The objective is to improve sustainability by enabling better decision‐making in policy and business contexts. The framework can be applied to any system of processes where available information supports discovery and quantification of ...

Connecting Health Promotion and Sustainable Development Goals to Enhance the Health of Agrifood Temporary Migrant Workers—a Scoping Review

Sustainable Development, EarlyView.
ABSTRACT Temporary migrant workers (TMW) in the agrifood system face social determinants of health (SDoH) that contribute to health inequities. Despite their dual residency, the potential of the Sustainable Development Goals (SDG) to support the health of TMW remains underexamined.

Overcoming Barriers and Solutions for Catalysing Private Capital in Climate Adaptation: A Stakeholder‐Informed Agenda for Hong Kong's Intermediary Role in Southeast Asia

Sustainable Development, EarlyView.
ABSTRACT This study investigates stakeholder perspectives on mobilising private‐sector finance for climate adaptation in Southeast Asia, emphasising Hong Kong's role as a financial intermediary. Through semi‐structured interviews with diverse stakeholders, including practitioners, policymakers, insurers, and project developers, we employed a grounded ...
