Multi‐scale flow analysis for scale‐aware urban canopy models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We found that scale‐aware models are necessary when numerical weather prediction models approach hectometric resolution, which is associated with a characteristic length‐scale of morphological heterogeneity. This morphology‐dependent length‐scale indicates that resolved and unresolved heterogeneity are equally important.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Effect of Different Surface Treatments on Resistance to Abrasive Wear of AISI 4140 Steel

steel research international, EarlyView.
This study investigates how different surface treatments affect resistance to abrasive wear of AISI 4140 Steel. The wear rate was significantly higher in samples subjected to conventional treatments than in samples coated using the HVOF process, demonstrating the superior efficiency of coatings applied by thermal spraying in mitigating abrasive wear ...

Transient CFD Study of Aerodynamic Interaction Between Heavy-Duty Trucks During Highway Merging and Platoon Formation Under Crosswind

Fluids
Highway merging and platoon formation are critical scenarios in heavy-duty vehicle aerodynamics. This study presents a transient computational fluid dynamics (CFD) analysis of two trucks undergoing a merging maneuver and subsequent platoon formation.

Ed Davey's Tory Removals: The Liberal Democrats and the 2024 General Election

The Political Quarterly, Volume 96, Issue 1, Page 83-90, January/March 2025.
Abstract The 2024 general election represented a remarkable comeback for the Liberal Democrats. Less than a decade on from the coalition and the 2015 election debacle, Sir Ed Davey's party reclaimed third‐party status in the House of Commons with seventy‐two MPs—the largest total for the Liberal Democrats or their Liberal Party predecessors since the ...

Staging friendship: towards an anthropology of everyday geopolitics in South Asia L'amitié mise en scène : vers une anthropologie de la géopolitique du quotidien en Asie du Sud

Journal of the Royal Anthropological Institute, EarlyView.
This article studies Indian‐Bangladeshi friendship ethnographically, as a contested political imaginary, claim, and relation, from the vantage of its shared borderlands. Staging friendship, I show, is a geopolitical project that engages equally the highest echelons of the Indian and Bangladeshi states and ordinary residents of its marginalized ...

The Political Ecology of the ‘New’ Feminism in Late‐1990s Britain

Gender &History, EarlyView.
ABSTRACT The 1990s were a vexed time for feminists in Britain. Cultural commentators declared that feminism's key battles had been won, and that given women's ascendency across various political and cultural barometers of success, the country was entering a newly ‘postfeminist’ era.

Analysis of a Low-Angle Annular Expander Nozzle

Shock and Vibration, 2015
An experimental and numerical analysis of a low-angle annular expander nozzle is presented to observe the variance in shock structure within the flow field. A RANS-based axisymmetric numerical model was used to evaluate flow characteristics and the model

Patient Safety and Organisational Accountability: Reassessing Criminal Liability Frameworks in Healthcare

The Modern Law Review, EarlyView.
Serious harm in healthcare often results from systemic failures, yet criminal accountability remains largely addressed through homicide law, gross negligence manslaughter and health‐and‐safety offences, frameworks that emphasise individual culpability and are ill‐suited to addressing organisational failings.
