Simulation of the Rotational Molding Process of Polyethylene Using the Smoothed Particle Hydrodynamics Method

Polymer Engineering &Science, EarlyView.
Numerical simulation of polyethylene rotational molding using the Smoothed Particle Hydrodynamics (SPH) method. ABSTRACT This work presents the development of a numerical model based on the smoothed particle hydrodynamics (SPH) method to simulate the rotational molding process of powder thermoplastic polymers, used in the manufacture of liners for high‐

Synthetic Aperture Imaging with ⊤-, $+$-, or $\times$-Shaped Arrays: Cartesian or Hexagonal Sampling?

Remote Sensing
The key performance of microwave imaging radiometers by aperture synthesis is governed by spatial resolution, radiometric sensitivity, and the extent of the synthesized field of view that is free from any aliasing artifact.

Translating Machine Learning Into Manufacturing Expertise—Actionable Interpretability and Stability for Precision Injection Molding

Polymer Engineering &Science, EarlyView.
This research aims to enhance confidence in using AI/ML models and address unpredicted defects occurred during injection molding (IM) through guided machine fine‐tuning. Integrated stability analysis and parallel coordinate visualization coupled with perturbation analysis are presented to augment domain‐specific XAI applications in the IM industry ...

Scaling turbulence drives the general circulation

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The NOAA Gulfstream SP4, which deployed the GPS dropsondes over the NE Pacific Ocean as part of the Winter Storms Project during the January–March periods of 2004, 2005 and 2006. Abstract Statistical multifractal analysis of airborne and dropsonde observations is used to show that persistence of velocity after molecular collisions breaks the continuous

New insights into convection‐permitting model simulations from a ZDR$$ {\boldsymbol{Z}}_{\mathbf{DR}} $$ diagnostic for raindrops

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A polarimetric radar forward operator to simulate differential reflectivity (ZDR$$ {Z}_{\mathrm{DR}} $$) from rain was developed to evaluate simulated storms in the Met Office Unified Model (MetUM) for two case days of the Wessex Convection Experiment (WesCon) field campaign. Vertical columns of ZDR$$ {Z}_{\mathrm{DR}} $$, indicative of strong updrafts,
