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.

Velocity Field and Entrainment of a Pulsed Core Jet

Journal of Fluids Engineering, 1981
A pulsed core jet is one consisting of a steady annular flow with a core, the mass flow of which is unsteady. The combined jet exhausts into a still environment. The velocity field and entrainment characteristics for such a jet have been measured for various mass flow ratios of pulsed-to-steady flow and several frequencies of pulsation.

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 ...

Core Fields of the RLS Framework

2010
In this chapter, I review literature in CR and formal systems with regard to the corefields of the generic leadership systems framework (Reichwald, Siebert & Moslein, 2005). The four core fields of instruments are (shortcuts in brackets): Leadership as a day-to-day interactive process (“interactive process”); leadership metrics (“metrics”); leadership ...

A lunar core and the moon's magnetic field

The Moon, 1975
The suggestion that the moon's magnetic field is due to adiabatic magnetohydrodynamic convection of a molten core has been made by a number of recent authors. Considerations based on petrology, mass and rotational inertia limit the size of this hypothetical core to a few hundred kilometers at the most.

Geomagnetic Core Field Models in the Satellite Era

2010
After a brief review of the theoretical basis and difficulties that modelers are facing, we present three recent models of the geomagnetic field originating in the Earth’s core. All three modeling approaches are using recent observatory and near-Earth orbiting survey satellite data. In each case the specific aims and techniques used by the modelers are

Electromagnetic core-mantle coupling torques for different magnetic field models and core velocity fields

2007
The electromagnetic (EM) core-mantle coupling torque is commonly split into a poloidal and toroidal part for its determination. The main reason for this splitting is the related splitting of the magnetic field, where the poloidal part only is observable outside the Earth.
