The metal detector can determine approximately how deep the object is buried based on the strength of the magnetic field it generates. The closer to the surface an object is, the stronger the magnetic field picked up by the receiver coil and the stronger the electric current generated. The farther below the surface, the weaker the field.

cient magnitude, these induced electric fields and currents can interact with electrically excitable nerve and muscle tissue. Generally, however, the surface charge effects of exposure to low frequency electric fields become prohibitive long before the internal electric fields become large enough to elicit a response in the tissue.

Jul 09, 2015· This paper focuses on the detection and classification of the faults on electrical power transmission line using artificial neural networks. The three phase currents and voltages of one end are taken as inputs in the proposed scheme. The feed forward neural network along with back propagation ...

A coalseam fire is a natural burning of an outcrop or underground coal coalseam fires exhibit smoldering combustion, particularly underground coalseam fires, because of limited atmospheric oxygen availability. Coalseam fire instances on Earth date back several million years. Due to fine thermal insulation and the avoidance of rain/snow extinguishment by the crust, underground ...

Jul 27, 2005· The binary classifier is used to decide between two key cases, namely whether an interface is within, for example, 5Â cm of the surface or not. This go/nogo detection capability is highly valuable for underground coal mining operations, such as longwall mining, where the need to leave a remnant coal section is essential for geological stability.
