Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...

Analysis of the Internal Anatomy of Distal Root Canals of Mandibular Molars: A Micro‐Computed Tomography Study

X-Ray Spectrometry, EarlyView.
ABSTRACT Detailed knowledge of the internal anatomy of the root canal system and its variations is essential for selecting appropriate endodontic treatment protocols. Micro‐computed tomography (micro‐CT) allows for nondestructive, high‐resolution three‐dimensional (3D) analysis of extracted teeth, enabling precise evaluation of root canal morphology ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions

X-Ray Spectrometry, EarlyView.
ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Lightweight Convolutional Neural Networks Model and Data Augmentation‐Based Background Regression for Rail Surface Defect Detection

Artificial Intelligence for Engineering, EarlyView.
An ultra‐lightweight semantic segmentation network RailNet with only 0.905 M parameters is proposed for rail surface defect detection. Combined with a CDBM image enhancement and GAN‐based data augmentation, RailNet achieves superior segmentation accuracy and real‐time speed on edge devices.

About the Ageing‐Induced Modifications of Physical‐Chemical and Electrical Properties of Polyimide (PMDA‐ODA) Under Gamma Radiation and High Temperatures

High Voltage, EarlyView.
ABSTRACT This study investigates the effects of radiation‐induced ageing on the physical, chemical, mechanical and electrical properties of Poly[4,4′‐oxydiphenylene‐ pyromellitimide] (PMDA‐ODA) polyimide, a high‐performance insulation material widely used in aerospace applications.
