Elastic-plastic properties of mesoscale electrodeposited LIGA nickel alloy films: microscopy and mechanics

November 22, 2020
Author(s)
Li-Anne Liew, David T. Read, May Martin, Frank W. DelRio, Peter E. Bradley, Nicholas Barbosa, Todd R. Christenson, John T. Geaney
The elastic-plastic properties of mesoscale electrodeposited LIGA Ni alloy specimens are investigated as a function of specimen size, strain rate, and material composition. Two material compositions are studied: a high-strength fine-grained Ni-Fe alloy and

An Analysis of the IOF Architecture – a Systems Integration Perspective

November 20, 2020
Author(s)
Boonserm Kulvatunyou, Minchul Lee, Megan Katsumi
The Industrial Ontology Foundry (IOF) describes its ontology architecture in the its charter wherein different types of ontologies are identified. These types ontologies are described at high-level in the charter. Their relationships and purposes are not

Chapter 4: Oxidatively induced DNA damage: Mechanisms and measurement

November 20, 2020
Author(s)
Miral M. Dizdar, Erdem Coskun, Gamze Tuna, Melis Kant, Pawel Jaruga
Oxidatively induced damage to DNA occurs in living organisms by endogenously or exogenously generated reactive species including free radicals. Mounting evidence suggests that this type of DNA damage plays an important role in the etiology of numerous

Evolution of the Magnetic Properties in the Antiferromagnet Ce 2 RhIn 8 Simultaneously Doped with Cd and Ir

We report the evolution of the magnetic properties of Ce 2Rh 1−xIr xIn 8−yCd y single crystals. In particular, for Ce 2Rh 0.5Ir 0.5In 8 (T N = 2.0 K) and Ce 2Rh 0.5Ir 0.5In 7.79Cd 0.21 (T N = 4.2 K), we have solved the magnetic structure of these compounds

Formalizing Performance Evaluation of Mobile Manipulator Robots using CTML

November 20, 2020
Author(s)
Omar Aboul-Enein, Yaping Jing, Roger V. Bostelman
Computation Tree Measurement Language (CTML) is a newly developed formal language that offers simultaneous model verification and performance evaluation measures. While the theory behind CTML has been established, the language has yet to be tested on a
