Computed tomographic beam-hardening artefacts: mathematical characterization and analysis [PDF]
Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2015 This paper presents a mathematical characterization and analysis of beam-hardening artefacts in X-ray computed tomography (CT). In the field of dental and medical radiography, metal artefact reduction in CT is becoming increasingly important as artificial prostheses and metallic implants become more widespread in ageing populations. Metal artefacts are

LHC Computing – the First 3 Decades [PDF]
EPJ Web of Conferences, 2021 Computing for the Large Hadron Collider (LHC) at CERN arguably started shortly after the commencement of data taking at the previous machine – LEP – some would argue it was even before.

Computed Tomography Beam Hardening Correction Based on Non-linear Segmentation [PDF]
International Journal Bioautomation, 2019 This paper aims to eliminate the hardening artifacts in computed tomography (CT) images caused by the polychromatic X-ray spectrum. To this end, a polynomial fitting correction method using non-liner segmentation method was developed through projection ...

A four parameter hardening model for TWIP and TRIP steels
Materials & Design, 2020 The mechanical behavior of twinning- and transformation-induced plasticity steels, commonly referred to as TWIP and TRIP steels, are characterized by linear hardening followed by an abrupt decrease in the hardening rate.

Toward Workable and Cost-Efficient Monitoring of Unstable Rock Compartments with Ambient Noise
Geosciences, 2021 Ambient Vibration-Based Structural Health Monitoring (AVB–SHM) studies on prone-to-fall rock compartments have recently succeeded in detecting both pre-failure damaging processes and reinforcement provided by bolting.

Experimental and computational determination of hardened zones during laser hardening of steels
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Experiments in defocus of beam rectangular-shaped fiber laser in the range of 30-65 mm. using a full factorial experiment, we constructed the surface to depth and width of the zone of hardening through varying the speed of the beam in the range of 15-20 mm/s, power 3-4 kW.
