Geomagnetic Jerks: Rapid Core Field Variations and Core Dynamics

Space Science Reviews, 2010
The secular variation of the core field is generally characterized by smooth variations, sometimes interrupted by abrupt changes, named geomagnetic jerks. The origin of these events, observed and investigated for over three decades, is still not fully understood.

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 ...

Magnetic field of a core barrel

Geological Society, London, Special Publications, 1995
Abstract The magnetic field associated with a core barrel is almost entirely restricted to a small volume near to its tip and is insignificant within the barrel, except immediately adjacent to the wall. At the tip of the barrel the field is lowest along its axis and directed almost entirely parallel to it.

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 ...
