Three-dimensional joint inversion of traveltime and gravity data across the Chicxulub impact crater
, 2009 In 2005 an extensive new seismic refraction data set was acquired over the central part of the Chicxulub impact crater, allowing us to image its structure with much better resolution than before.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

The application of seismic surveys to the evaluation of shallow coal deposits [PDF]
, 1986 The viability of using surface seismic techniques in the exploration of shallow coal deposits in the UK is investigated. The geological factors that affect the economic viability of a prospective site are the overburden ratio and the presence of faulting,

Refraction Correction for Spectrally Derived Bathymetry Using UAS Imagery
Remote Sensing, 2023 Spectrally derived bathymetry (SDB) algorithms are rapidly gaining in acceptance and widespread use for nearshore bathymetric mapping. In the past, refraction correction could generally be ignored in SDB, due to the relatively small fields of view (FOVs)

Influence of age on peripheral refraction [PDF]
, 2005 To investigate how age affects peripheral refraction we measured objective peripheral refraction for 55 young subjects (24±4 years) and 41 older subjects (59±3 years) out to 35° eccentricity in temporal and nasal visual fields.

Accuracy and precision of automated subjective refraction in young hyperopes under cycloplegia [PDF]
, 2023 Purpose: To assess the agreement between the Eye Refract, an instrument to perform subjective automated refraction, and the traditional subjective refraction, as the gold standard, in young hyperopes under noncycloplegic and cycloplegic conditions ...

Additive Manufacturing of Alumina‐Reinforced Elastomers
Advanced Engineering Materials, EarlyView.Vat‐photopolymerized elastomers reinforced with platelet‐shaped alumina exhibited preferential orientation, reduced porosity, and significantly enhanced mechanical performance. A 3 wt% platelet loading increased tensile strength from 12.4 to 45.7 MPa, highlighting the critical role of filler morphology in elastomeric VPP composites.
