Geomagnetic Core Field Secular Variation Models

Space Science Reviews, 2009
We analyse models describing time changes of the Earth’s core magnetic field (secular variation) covering the historical period (several centuries) and the more recent satellite era (previous decade), and we illustrate how both the information contained in the data and the a priori information (regularisation) affect the result of the ill-posed ...

Field Server Engine as Hardware core of Field Servers

Computers in Agriculture and Natural Resources, 23-25 July 2006, Orlando Florida, 2013
Field Server is composed of durable casing, Web-server, multiple sensors, network-camera, wireless LAN card, high intensity LED lighting etc. The most important part in Field Server is a core card, Field Server Engine (FSE). The FSE functions as Web server, advanced data acquisition system (16ch), signal generator, remote controller for external ...

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 ...

Field-Deployed Multi-Core Fiber Testbed

2019 24th OptoElectronics and Communications Conference (OECC) and 2019 International Conference on Photonics in Switching and Computing (PSC), 2019
We installed a multi-core fiber (MCF) cable in underground tunnels in a city in Italy, without significant crosstalk degradation in uncoupled MCFs, and with the lowest-ever spatial mode dispersion in randomly-coupled MCFs.

The Temperature Field of the Body Core

2001
For many aspects of temperature regulation, it is sufficient to treat the temperature of the body core as a uniform entity. However, it is a simplification. The temperature of an organ, and, in fact, of any site within it, depends on the temperature of the arterial blood flowing into the organ, local heat production and local rate of blood flow.

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.

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 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.

Coring in the Oklahoma City Field

Transactions of the AIME, 1933
Abstract The author has made a statistical analysis of the relations between recoveryand length of cores, diameters of cores and of drill pipe, and cost of coringunder different contractual conditions. The data are presented in tabularform.
