Computer process planning of induction hardening

2001
Phases in setting up the induction hardening procedure have been discussed. For the exact definition of working parameters, computer simulation is recommended. For the axially symmetric work-pieces a special simulation program has been developed.

Demonstration of Beam Hardening Correction in Computed Tomography of the Head

Journal of Computer Assisted Tomography, 1979
The efficacy of a method of removing artifacts due to beam hardening in computed tomography of the human head is demonstrated on a realistic, mathematically described phantom. An efficient implementation is discussed.

A beam-hardening correction using dual-energy computed tomography

Physics in Medicine and Biology, 1985
The problems associated with beam hardening in X-ray transmission computed tomography (CT) have been described by Brooks and DiChiro (1976). These include the introduction of non-linear artefacts in CT images with corresponding errors of as high as 10% in CT measurements of the linear attenuation coefficient, thus severely limiting the use of CT in ...

Hardening OpenStack Cloud Platforms against Compute Node Compromises

Proceedings of the 11th ACM on Asia Conference on Computer and Communications Security, 2016
Infrastructure-as-a-Service (IaaS) clouds such as OpenStack consist of two kinds of nodes in their infrastructure: control nodes and compute nodes. While control nodes run all critical services, compute nodes host virtual machines of customers. Given the large number of compute nodes, and the fact that they are hosting VMs of (possibly malicious ...

Multi-material linearization beam hardening correction for computed tomography

Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 2017
Beam hardening causes cupping and streaking artifacts in computed tomographic images, the presence of such artifacts can impair both qualitative and quantitative analysis of the reconstructed data. When the scanned object is composed of a single material, it is possible to correct beam hardening artifacts using the linearization method.

Computer predictions of progressive induction hardening of cylindrical components

Materials Science and Technology, 1985
Abstract In this paper progressive induction hardening is treated mainly on a theoretical basis. In contrast to stationary induction hardening, the progressive treatment makes it necessary to include a heat flow in the axial direction of the work piece; a single coil also leads to a magnetic field which changes in the axial direction.

Modification of Hardening Parameter for Computational Plasticity

2017
ABSTRACTHardening can be defined as increase in the strengthof a material due to plastic deformation. A type of hardening, which is workhardening, is performed under the cold working conditions. In metallic solidspermanent change of shape is generally carried out on a microscopic scale bydefects called dislocations which are created by stress.

Radiation-hardened 32-bit single board computer

16th DASC. AIAA/IEEE Digital Avionics Systems Conference. Reflections to the Future. Proceedings, 2002
Most of the cost for developing a computing solution for space and launch vehicles is in the development of the software. Thus, space-qualified computing hardware, supported by mature software development tools, is very desirable. Honeywell, under contract with the Air Force Rome Laboratory, has developed a radiation-hardened processor based on the ...

Electron beam surface hardening utilizing computer control

Journal of Heat Treating, 1983
Computer Controlled Electron Beam Machines, which are capable of precise beam placement and heat input, provide a means for localized surface hardening of steel. Minimal heat input to parts, which are selfquenched, reduces part distortion and eliminates post processing.
