Physica Scripta, 1975
The spectrum of Fe V has been observed by using a vacuum sliding-spark discharge and the 10.7-m grazing-incidence spectrograph as well as the 10.7-m normal-incidence spectrograph at the National Bureau of Standards, Washington. Almost 1 000 lines have been identified in the region 302-1 715 Å, and all levels of 3d4and all but one level in each of the ...

COMPEL: The International Journal for Computation and Mathematics in Electrical and Electronic Engineering, 2015
Purpose– The consideration of uncertainties in the numerical computation of electromagnetic fields has recently gained a lot of attention. Most publications focus on the creation of models for the uncertainty quantification, however, neglect the inaccuracy of the applied finite element model itself.

NMR analysis of ferromagnets: Fe oxides
Solid State Nuclear Magnetic Resonance, 2009A short historical review is given on internal field NMR of ferromagnets, illustrated with recent pulsed NMR spectra of the elemental ferromagnets Fe, Co and Ni and the Fe-oxides magnetite, maghemite and hematite, which, with the exception of maghemite, have resonance frequencies first reported over 45 years ago.

Structural and magnetic analysis of MBE-grown Fe/Si/Fe and Fe/Ge/Fe sandwiches
Journal of Magnetism and Magnetic Materials, 1997Abstract The structure and the interlayer exchange coupling in MBE-grown nominal Fe/Ge1−xFex/Fe(x=0.0, 0.25, 0.33, 0.5) and Fe/Si/Fe sandwiches with wedge-shaped spacer layers were investigated. In the case of Fe/Si a sample with a wedge-shaped magnetic layer was also studied. From a structural analysis with LEED and from a magnetic analysis with the

FE analysis of continuous shear connector
IABSE Congress Reports, 2021<p>Composite bridges with encased steel beams, or nowadays, rather encased steel continuous shear connectors are a welcome option for short span railway or road bridges. With lower construction height and easy construction of prefabricated composite beams it brings a new, complex, solution for replacement of older, overserved bridges, as well as ...

PIXE analysis of Fe content in Fe-implanted GaN film
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006The diluted magnetic semiconductors (DMSs) were achieved by the ion implantation. Fe+ ions (250 keV) were implanted into n-type GaN at room temperature with doses ranging from 8 X 10(15) cm(-2) to 8 X 10(16) cm(-2) and subsequently rapidly annealed at 800 degrees C for 5 m in N-2 ambient. PIXE was employed to determine the Fe-implanted content.

An analysis of the phase equilibria in the Fe−FeS system
Metallurgical Transactions B, 1975Applying a previously developed thermodynamic model to available experimental data from different phase equilibria in the Fe−FeS system, an attempt has been made to reconcile the results from different investigations. Analytical expressions for the free energy of the individual phases are recommended.

Quantitative AES analysis of Fe-Cr and Fe-Ni-Cr alloys
Applications of Surface Science, 1983Abstract Conventional, derivative mode AES, in combination with Ar + sputtering, was applied to a wide range of commercial Fe-Cr and Fe-Ni-Cr alloys. The roles played by matrix effects, sputtering phenomena, peak interference, peak height variation and poor vacuum backpressure in obtaining quantitative analyses were studied.

Automated FE analysis of flange assemblies
Sealing Technology, 1996Abstract An automated finite element computer program to analyse bolted circular weld neck flange and gasket assemblies has been developed. The program is based on an extensive database of British, European and American flange and gasket standards. The program is ideal for identifying problem areas and conducting sensitivity studies.
