Radiation-hardened 32-bit single board computer
16th DASC. AIAA/IEEE Digital Avionics Systems Conference. Reflections to the Future. Proceedings, 2002Most 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 ...

Computer Simulation of Single-Shot Induction Hardening Processes
Heat Treating Conference, 2017Abstract In single-shot hardening applications, heat treated components often feature a variety of geometric complexities including variable wall thicknesses, sharp diameter transitions, lightening holes, slots, etc. Due to the inherent 3D electromagnetic nature of single-shot coils and the complex geometry components which they must ...

Hardening OpenStack Cloud Platforms against Compute Node Compromises
Proceedings of the 11th ACM on Asia Conference on Computer and Communications Security, 2016Infrastructure-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, 2017Beam 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 simulation study of short-range order hardening
Metallurgical Transactions A, 1990Computer simulation is used to analyze the short-range order hardening (SROH) effect in Cu-25 at. pct Au. It is confirmed that the subsequent dislocations randomize the state of order of a system.

Computational mesomechanics of titanium surface-hardened by ultrasonic treatment
Physical Mesomechanics, 2017This paper studies plastic strain localization and stress-strain evolution in commercial titanium specimens with an ultrasonically treated surface. A dynamic plane strain boundary-value problem is numerically solved by the finite difference method. The microstructure and mechanical properties of the composition are specified in the calculations based ...

Modification of Hardening Parameter for Computational Plasticity
2017ABSTRACTHardening 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.

Enhancing the performance of radiation-hardened embedded computer systems
Russian Microelectronics, 2006Adaptive clock-rate switching is discussed in terms of enhancing the performance of radiation-hardened embedded computer systems. Clock rate is optimized by evaluating the closeness of the current failure rate to its maximum allowable level.
