Correction for beam hardening in computed tomography

Medical Physics, 1978
Corrections for beam-hardening artifacts in computed tomography can be made by using a model which assumes that water and bone mineral are the only constituents of tissue. With this model, a correction factor for the measured transmission values can be calculated such that the reconstructed attenuation coefficients have values corresponding to a ...

Computer simulation of induction hardening

Journal of Materials Processing Technology, 2004
The computer simulation of electromagnetic, thermodynamic and microstructural transformations in treated work-piece is usually recommended for the exact definition of working parameters in process planning of the induction hardening processes. A special simulation program has been developed for the axially symmetric work-pieces.

Computer thermal model for hardening grinding

Journal of Engineering Physics and Thermophysics, 2000
A mathematical model of heat transfer in steel parts under force grinding is considered that allows one to determine the grinding parameters at which a steel layer of prescribed thickness is heated up to hardening temperatures. Results of numerical simulation of the process of hardening grinding are compared with experimental data.

System Level Hardening by Computing with Matrices

2010 13th Euromicro Conference on Digital System Design: Architectures, Methods and Tools, 2010
Continuous advances in transistor manufacturing have enabled technology scaling along the years, sustaining Moore's law. As transistors sizes rapidly shrink, and voltage scales, the amount of charge in a node also rapidly decreases. A particle hitting the core will probably cause a transient fault to spam over several clock cycles.

Correction for beam hardening in computed tomography

Physics in Medicine & Biology, 1979
We investigate how one can estimate from the total attenuation, p, of a polyenergetic X-ray beam what the total attenuation, m, of a monoenergetic beam would have been along the same ray. We find that for beams with typical diagnostic X-ray spectra passing through the human body one can find a simple function f such that f(p) is a sufficiently close ...
