Atmospheric Characterization For Optical Paths In Lunar Proximity, Patrick D. Carattini

Theses and Dissertations

This paper presents a novel technique for estimating the Fried seeing parameter (r0) for optical paths around the Moon, where traditional methods fail due to the Moon's intensity. Using image processing, it derives the atmospheric optical transfer function (OTF) by using the Moon's edge as a step-input. A simulation chain validates the approach, achieving r0 estimation within 0.0012 m. Real-world tests confirm accuracy through visual and statistical analysis, offering an effective alternative for atmospheric characterization of optical paths close to the moon.

Economic Coercion And Grey Zone Competition: Reassessing The China-Australia Case, Naoise Mcdonagh, Sascha Dominik Dov Bachmann

Research outputs 2022 to 2026

Economic coercion is recognized as a major policy challenge for global leaders. The case of Beijing’s use of economic coercion against Australia (2020–2024) in response to bilateral tensions holds important insights. Research shows that China’s coercion efforts failed in two ways: the total costs to Australia’s economy were smaller than expected, and Canberra did not change pre-existing policies that triggered the coercion. Failure in this case is attributed to the ability of markets to adjust. Building on this research, we argue that while markets adapted relatively well in the Australia-China case, coercion still produced significant and concentrated subnational costs that …
