Affinification: A Fine Approximation of Deformations

Computer Graphics Forum, EarlyView.
Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

Disintegration and Skipping Dynamics of Bilobate‐Shaped Meteoroids for Generating Ultra‐Long Strewn Fields

Earth and Space Science
The longest known Aletai meteorite belt presents a unique phenomenon in meteoroid dynamics. To investigate its formation mechanism, this study introduces a bilobate‐shaped meteoroid model, emphasizing aerodynamic interactions and structure evolution. The

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

Geostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Multidimensional Militarisation, Evidence From Mexico's War on Drugs

International Social Science Journal, EarlyView.
ABSTRACT This article documents different dimensions of militarisation observed in Mexico since the start of the war on drugs. It argues that militarisation is a multidirectional phenomenon that is characterised by rationales that justify the use of illegal means to address complex issues, promising expediency and efficiency but rarely delivering on it.

Autonomous spectrographic system to analyse the main elements of fireballs and meteors

Earth, Planets and Space, 2018
We present a meteor observation system based on imaging CCD cameras, wide-field optics and a diffraction grating. This system is composed of two independent spectrographs with different configurations, which allows us to capture images of fireballs and ...

Exploring Complex Historical Figures through a Modified Critical Making Framework

International Journal of Art &Design Education, EarlyView.
Abstract This paper examines ‘critical making’ as a framework for exploring complex problems and topics. Critical making combines an iterative process of making with research, reflection and analysis. The authors present a modified critical making process that builds on the reflexive material engagement introduced by the originator of critical making ...
