Flight test trajectory control analysis [PDF]

open access: yes
Recent extensions to optimal control theory applied to meaningful linear models with sufficiently flexible software tools provide powerful techniques for designing flight test trajectory controllers (FTTCs).

Evaluation of Iterative DBD Procedures for Bridges [PDF]

open access: yes, 2007
This report addresses the problem of the Displacement Based Evaluation/Design (DBE/D) of reinforced concrete bridges. Throughout the report, the aims and limitations of current seismic evaluation and design practice and the tendencies of the displacement-

Ultrasonographic diagnosis of caudoproximal humeral stress fracture in thoroughbred racehorses

open access: yesEquine Veterinary Journal, Volume 58, Issue 3, Page 788-796, May 2026.
Abstract Background Humeral stress fractures in racehorses can progress to catastrophic fracture if unrecognised. Scintigraphy is the gold standard diagnostic technique but is limited by accessibility and cost. It was hypothesised that ultrasonography could be used to visualise caudoproximal humeral stress fractures. Objectives To determine the utility

Kinship‐based deference among Jaru siblings: A collaborative, adaptive, and multimodal accomplishment

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract In the Jaru community of northern Western Australia, certain in‐laws and relatives are categorized as being in a highly respectful relationship in which they are expected to pay deference to one another. This conversation‐analytic study closely examines the deferential practices that are used among three Jaru siblings in an ordinary multi ...

Distinct Characteristics of Contiguous Heatwaves Across Terrestrial, Marine, and Coastal Environments

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Atmospheric extreme heat is intensifying across terrestrial, marine, and coastal environments, impacting ecosystems, society, and other extremes, such as drought and marine heatwaves. We quantify the characteristics of contiguous near‐surface heatwaves using ERA5 (December 1940–November 2024) and find significant differences across these ...

Preliminary flight-determined subsonic lift and drag characteristics of the X-29A forward-swept-wing airplane [PDF]

open access: yes
The X-29A subsonic lift and drag characteristics determined, met, or exceeded predictions, particularly with respect to the drag polar shapes. Induced drag levels were as great as 20 percent less than wind tunnel estimates, particularly at coefficients ...

Scour‐Conditioned Seismic Fragility Analysis of Monopile‐Supported Offshore Wind Turbines

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 947-967, 10 April 2026.
ABSTRACT Monopile‐supported offshore wind turbines (MS‐OWTs) are increasingly deployed in seismic coastal regions, where they face compound risks from earthquake loading and seabed scour. While past studies have addressed these hazards separately, seismic fragility under evolving scour conditions remains insufficiently understood. This study introduces

Pushover Analysis of Retrofitted Reinforced Concrete Buildings [PDF]

open access: yes, 2015
For the past decade or more, the structural engineering profession has been using the nonlinear static procedure (NSP) or pushover analysis. Modeling for such analysis requires the determination of nonlinear properties of each component in the structure,
