Effect of Leading Edge Protuberance on Thrust Production of a Dynamically Pitching Aerofoil [PDF]
, 2017 The paper presents a computational analysis of the characteristics of a NACA 634-021 aerofoil modified by incorporating sinusoidal leading-edge protuberances at Re = 14,000.

Source levels of foraging humpback whale calls [PDF]
The Journal of the Acoustical Society of America, 2018 Humpback whales produce a wide range of low- to mid-frequency vocalizations throughout their migratory range. Non-song “calls” dominate this species' vocal repertoire while on high-latitude foraging grounds. The source levels of 426 humpback whale calls in four vocal classes were estimated using a four-element planar array deployed in Glacier Bay ...

Entropy, 2008 We assess the effectiveness of applying information theory to the characterization and quantification of the affects of anthropogenic vessel noise on humpback whale (Megaptera novaeangliae) vocal behavior in and around Glacier Bay, Alaska.

Perceptually Motivated Wavelet Packet Transform for Bioacoustic Signal Enhancement [PDF]
, 2008 A significant and often unavoidable problem in bioacoustic signal processing is the presence of background noise due to an adverse recording environment. This paper proposes a new bioacoustic signal enhancement technique which can be used on a wide range

Epigenetic estimation of age in humpback whales [PDF]
Molecular Ecology Resources, 2014 AbstractAge is a fundamental aspect of animal ecology, but is difficult to determine in many species. Humpback whales exemplify this as they have a lifespan comparable to humans, mature sexually as early as 4 years and have no reliable visual age indicators after their first year.

Numerical Investigation on Flow Separation Control of Low Reynolds Number Sinusoidal Aerofoils [PDF]
, 2016 The paper presents a computational analysis of the characteristics of a NACA 634- 021 aerofoil incorporated with sinusoidal leading-edge protuberances at Re = 14,000. The protuberances are characterized by an amplitude and wavelength of 12% and 50% of

Great Meteor Seamount Circulation Revisited: Insights Into Cold‐Water Coral Habitat Potential
Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.Abstract Seamounts play a crucial role in shaping deep‐sea ecosystem structure, influencing ocean circulation, enhancing biological productivity, and supporting diverse marine life. The Great Meteor Seamount (GMS), is the largest seamount in the North Atlantic and a key ecological feature in the regional network of the Protected Areas of the Azores ...
