Influence of sound reflection on aircraft directivity and lateral attenuation on the ground (2019)
Presentation / Conference
lateral attenuation on the ground. Presented at Internoise 2019, Noise Control for a Better Environment, Madrid, Spain

The calculation of the lateral attenuation correction for computing aircraft noise
footprints on the ground, as proposed by Doc29 and AIR5662, is based on
semiempirical methods not suitable for accounting for the particular
characteristics of some... Read More about Influence of sound reflection on aircraft directivity and lateral attenuation on the ground.

Psychoacoustic Characterisation of a Small Fixed-pitch Quadcopter (2019)
Presentation / Conference
Torija Martinez, A., Self, R., & Lawrence, J. (2019, June). Psychoacoustic Characterisation of a Small Fixed-pitch Quadcopter. Presented at Internoise 2019, Noise Control for a Better Environment, Madrid, Spain

In this study, a series of acoustic measurements were taken on a small fixed-pitch quadcopter, both in a controlled indoor acoustic environment and while flying outdoors. At controlled indoor conditions, audio signatures were recorded with the quadco... Read More about Psychoacoustic Characterisation of a Small Fixed-pitch Quadcopter.

Measuring the radiation exposure of Norwegian reindeer under field conditions (2019)
Journal Article

Models and approaches have been developed to predict radiation exposure of wildlife under field conditions. However, there have been few attempts to directly measure radiation exposure of wildlife in the field and confirm the doses predicted by model...

Reconstructing reef fish communities using fish otoliths in coral reef sediments (2019)
Journal Article
Lin, C.-H., De Gracia, B., Pierotti, M. E., Andrews, A. H., Griswold, K., & O'Dea, A. (2019). Reconstructing reef fish communities using fish otoliths in coral reef sediments. PloS one, https://doi.org/10.1371/journal.pone.0218413

Little is known about long-term changes in coral reef fish communities. Here we present a new technique that leverages fish otoliths in reef sediments to reconstruct coral reef fish communities. We found over 5,400 otoliths in 169 modern and mid-Holo... Read More about Reconstructing reef fish communities using fish otoliths in coral reef sediments.

Refining the late-Holocene coastline and delta development of the northern Yangtze River delta : combining historical archives and OSL dating (2019)
Journal Article

Historical documents provide a general chronological overview of the environmental evolution of the Yangtze River delta (YRD) during the last ca. 2000 years; however, absolute dating of the region’s late Holocene sediment is relatively rare. Opticall... Read More about Refining the late-Holocene coastline and delta development of the northern Yangtze River delta : combining historical archives and OSL dating.

Experimental investigation of temperature distribution in non - heated and pre - heated hot mix asphalt patch repair (2019)
Presentation / Conference
Byzyka, J., Rahman, M., & Chamberlain, D. (2019, June). Experimental investigation of temperature distribution in non - heated and pre - heated hot mix asphalt patch repair. Presented at 7th International Conference on Bituminous Mixtures and Pavements (7th ICONFBMP), Thessaloniki, Greece

The study focuses on the issue of hot mix asphalt patch repairs, the performance of which is greatly reduced by repair edge disintegration. This is caused by low interface temperatures during the repair operation which result in poor bonding between...

Acoustic characterization of additive manufactured perforated panel backed by honeycomb structure with circular and non-circular perforations (2019)
Journal Article

This paper studies the acoustic properties of an additive manufactured micro-perforated panel backed by a periodic honeycomb structure. Extrusion-based Fused Filament Fabrication (FFF) technique of Additive Manufacturing (AM) is used to fabricate the...

Assessing equilibria of organo-arsenic complexes and predicting uptake of arsenic by wheat grain from organic matter amended soils (2019)
Journal Article

In view of limited information, a laboratory experiment was conducted to study the stability of organo-arsenic complexes as affected by competing anions i.e. phosphate, nitrate and sulphate. For this purpose, humic acid (HA) and fulvic acid (FA) were...
