Hardening functions for large scale distributed computations
Proceedings 19th International Conference on Data Engineering (Cat. No.03CH37405), 2004The past few years have seen the development of distributed computing platforms designed to utilize the spare processor cycles of a large number of personal computers attached to the Internet in an effort to generate levels of computing power normally achieved only with expensive supercomputers.

Computer thermal model for hardening grinding
Journal of Engineering Physics and Thermophysics, 2000A 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.

Correction for beam hardening in computed tomography
Physics in Medicine & Biology, 1979We 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 ...

A computational model for the prediction of steel hardenability
Metallurgical and Materials Transactions B, 1998A computational model is presented in this article for the prediction of microstructural development during heat treating of steels and resultant room-temperature hardness. This model was applied in this study to predict the hardness distribution in end-quench bars (Jominy hardness) of heat treatable steels.

Capturing Returned Computable Values in AspectJ for Security Hardening
Information Security Journal: A Global Perspective, 2009The main contribution of this paper is to present an extension to AspectJ compiler ajc-1.5.0 for security hardening. The extension consists of two pointcuts that can capture the returned computable values of methods in both the execution scope and following a method invocation.

Development of a Computer Model for Induction Hardening of Steel
Materials, 2003Induction hardening is an important manufacturing process to control the mechanical properties of metal parts where surface hardness is enhanced while the core retains the toughness. This paper presents the modeling and simulation of the induction hardening processes with the finite element analysis.

Computer simulaton of induction hardening
2001The 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.

Computation of the Thickness of the Hardened Layer of Cemented Parts
Metal Science and Heat Treatment, 2004Mathematical dependences are suggested for determination of modes of thermochemical treatment (TCT) and choice of the grade of steel that would provide the required thickness of the hardened layer and the minimum deformations on cemented parts. The effective thickness of the layer is evaluated in terms of the criterion of full hardening for martensite ...

Beam Hardening Corrections in Quantitative Computed Tomography
AIP Conference Proceedings, 2007Volumetric computed tomography (VCT) is the emerging 3D NDE inspection technique that gives highest throughput and better image quality. Industrial components in general demands higher x‐ray energy for inspection for which polychromatic x‐ray sources are used in common.
