Broadband reflected wavefronts manipulation using structured phase gradient metasurfaces

AIP Advances, 2016
Acoustic metasurface (AMS) is a good candidate to manipulate acoustic waves due to special acoustic performs that cannot be realized by traditional materials. In this paper, we design the AMS by using circular-holed cubic arrays.

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Automated Feature Extraction and Classification of Submerged Cultural Heritage Assets in the Puck Lagoon via Multisensor Remote Sensing

Archaeological Prospection, EarlyView.
ABSTRACT This study presents a strong framework for the detection and classification of Submerged Cultural Heritage Assets (SCHA) in shallow marine environments using the integration of multibeam echosounder and airborne LiDAR bathymetry with object‐based image analysis and fuzzy logic–based classification.

The Building That Teaches: Exploring Augmented Reality Affordances in Academic Incubators

Journal of Interior Design, EarlyView., 2022
ABSTRACT Efforts to enhance the experience of interior environments have led to experimentation with augmented reality (AR) technology to encourage users to participate in the built space using their mobile devices. To investigate the role of AR technologies in interior design experiences, we highlight the interdisciplinary design of a mobile AR ...

Real-Time Acoustic Holography for Target Pattern Acoustic Field Reconstruction With Iterative Unsupervised Learning

IEEE Access
The ability to reconstruct acoustic field is essential for applications such as particle manipulation, medical therapy, and ultrasonic imaging. Conventional acoustic field reconstruction algorithms are limited in both speed and accuracy when generating ...

Mesoscale Acoustical Cylindrical Superlens

MATEC Web of Conferences, 2018
We demonstrate experimentally for the first time the acoustojet (acoustic jets) formed from acoustic plane wave scattering by a penetrable cylindrical particle with dimensions of several wavelengths. It acts as a superlens with subwavelength localization

Publicly funded private schools and academic achievement: A comparative analysis of PISA data in European countries

British Educational Research Journal, EarlyView.
Abstract This paper analyses differences in academic achievement associated with attendance at publicly funded private schools and public schools across 11 European countries. Using eight waves of PISA data (2000–2022), we apply OLS, IPW and IPWRA estimators to account for observed heterogeneity and mitigate selection bias.

Three-dimensional acoustic lens

, 2010
[ES] Se describe una lente acústica tridimensional con simetría de revolución para focalizar, colimar o dispersar haces sonoros. Las lentes están fonnadas por anillos concéntricos de un material con propiedades acústicas diferentes del las del medio en que se hallan inmersos y por tanto actuando como dispersores del sonido.
