Polygon Mesh Generation of Branching Structures [PDF]

, 2005
We present a new method for producing locally non intersecting polygon meshes of naturally branching structures. The generated polygon mesh follows the object's underlying structure as close as possible, while still producing polygon meshes that can be visualized efficiently on commonly available graphic acceleration hardware.

Monte Carlo estimation of radiation dose in organs of female and male adult phantoms due to FDG-F18 absorbed in the lungs

EPJ Web of Conferences, 2014
The determination of dose conversion factors (S values) for the radionuclide fluorodeoxyglucose (18F-FDG) absorbed in the lungs during a positron emission tomography (PET) procedure was calculated using the Monte Carlo method (MCNPX version 2.7.0).

Differential reflectivity columns and hail: Linking C‐band radar‐based estimated column characteristics to crowdsourced hail observations in Switzerland

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Differential reflectivity columns (ZDRC$$ {Z}_{\mathrm{DR}}C $$) have been detected automatically on a composite of radar data derived from five operational C‐band dual‐polarization Doppler weather radars in Switzerland. The characteristics of the detected ZDRC$$ {Z}_{\mathrm{DR}}C $$ are linked to a large sample of 173,000 crowdsourced hail ...

WindPoly: Polygonal Mesh Reconstruction via Winding Numbers [PDF]

arXiv
Polygonal mesh reconstruction of a raw point cloud is a valuable topic in the field of computer graphics and 3D vision. Especially to 3D architectural models, polygonal mesh provides concise expressions for fundamental geometric structures while effectively reducing data volume. However, there are some limitations of traditional reconstruction methods:

A Framework to Enable Eco‐Cyber‐Physical Systems for Robotics‐Focused Digital Twins in Smart Farming

Journal of Field Robotics, EarlyView.
ABSTRACT This paper introduces the R‐ECPS (Robotics‐focused Eco‐Cyber‐Physical System) framework for the development of robotics‐enabled digital twins, integrating human knowledge into the decision‐making process. Our framework adapts ECPS and Digital Twin (DT) definitions to agricultural field robotics.
