Hierarchical Differentiable Fluid Simulation

Computer Graphics Forum, EarlyView.
We introduce a two‐step algorithm that significantly reduces memory usage for solving control problems using differentiable fluid simulation techniques: our method first optimizes for bulk forces at reduced resolution, then refines local details over sub‐domains while maintaining differentiability. In trading runtime for memory, it enables optimization

A Survey of Methods for Constructing 3D Urban Models From Point Clouds

Computer Graphics Forum, EarlyView.
The survey outlines a general process for constructing 3D models from point clouds and categorizes the methods based on their use of templates, basic surface primitives, hybrid approaches, or linear primitives. Additionally, the survey reviews the datasets and benchmarks that are essential for testing and training the developed methods.

Numerical Modeling of Hydrogen‐Assisted Cracking With Phase Field Regularized Cohesive Zone Model and Penalty‐Based Moving Hydrogen Boundary Condition

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

Specification Tests for Jump‐Diffusion Models Based on the Characteristic Function

International Statistical Review, EarlyView.
Summary Goodness‐of‐fit tests are suggested for several popular jump‐diffusion processes. The suggested test statistics utilise the marginal characteristic function of the model and its L2‐type discrepancy from an empirical counterpart. Model parameters are estimated either by minimising the aforementioned L2‐type discrepancy or by maximum likelihood ...

A spectral analysis extension to DEMATEL for strategic leverage points identification

International Transactions in Operational Research, EarlyView.
Abstract Efforts to intervene in complex systems often emphasize influential factors, yet system behavior is equally shaped by the relationships among them. Methods such as Decision‐Making Trial and Evaluation Laboratory (DEMATEL) map causal structures but remain descriptive and do not identify which relationships provide the greatest leverage for ...

On the conflict between science and ethics: the case of the moggel, Labeo umbratus (Teleostei: Cyprinidae) from South Africa

Journal of Fish Biology, EarlyView.
Abstract Recent molecular evidence showed that Labeo umbratus comprises two allopatrically distributed genetic lineages, a northern lineage confined to the Orange‐Vaal River system where this species was originally described and a southern lineage with three geographically separated haplogroups (western, central and eastern) distributed across multiple
