High-Field Iron Core Magnets

IEEE Transactions on Nuclear Science, 1971
Compact, highly saturated iron window frame dipoles and quadrupoles have been computed with computer programs. Systematic and random aberrations in relation with the saturation have been studied.

Field Consolidation of Fractured Core

Journal of Petroleum Technology, 1959
Abstract A recent investigation of fractured core from the Embar reservoir of the Gebo field, Hot Springs County, Wyo., utilized novel techniques that are believed to be worth reporting. The most successful procedure was to: - cut the interval with a rubber sleeve core barrel ...

Electromagnetic field diffusion in axisymmetric hysteretic cores

IEEE International Digest of Technical Papers on Magnetics Conference, 2002
Summary form only given. The analysis of electromagnetic field diffusion is essential in different engineering applications, such as the design of electrical machines and actuators, induction heating, etc. This problem is often made complex by the hysteretic behaviour of the ferromagnetic materials, by eddy currents arising in the core and by the ...

Modeling protein cores with Markov random fields

Mathematical Biosciences, 1994
A mathematical formalism is introduced that has general applicability to many protein structure models used in the various approaches to the "inverse protein folding problem." The inverse nature of the problem arises from the fact that one begins with a set of assumed tertiary structures and searches for those most compatible with a new sequence ...

Interpretation of Core Field Models

2010
In this chapter we review several recent research results on the observed geomagnetic secular variation and secular acceleration, the core flow models inferred from these observations, and their implications, in particular those of the torsional oscillations, on short period secular variation and on the dynamical properties inside the core.

The fluxgate ring-core internal field

Measurement Science and Technology, 2002
A large number of measured demagnetizing factors for fluxgate ring cores of a wide range of cross section shapes have been compiled from the literature and plotted against the core cross-sectional area over the squared mean core diameter. The points group close to a straight line through the origin.

Core and crustal geomagnetic fields

Journal of Geophysical Research: Solid Earth, 1983
The spherical harmonic content of fields from core sources and that from extended crustal sources overlap so much that very long wavelength anomalies obtained by subtracting a core field model up to only degree 10 from the observations will be distorted so badly that interpretation in terms of geological sources will be difficult.
