In this paper, the author introduces the method of separation of magnetic field step by step, which supposes the field arises from an equivalent unit-thickness layer, whose equivalent magnetization is variable, then the equivalent magnetization of the equivalent unit-thickness layer is inversed by separating the field, finally, the magnetic geologic interface is determined by inversing ...

Method. The DANTE and T 2-preparation modules were combined into a single ASL sequence. T 2 values under the application of DANTE were determined to evaluate changes in T 2, along with the post-labeling delay (PLD) and the relationship between transit time without DANTE (TT noVS) and T 2. The reference tissue T 2 (T 2_ref) was also obtained ...

The invention relates to means of generating electrical energy. A method for generating electrical energy is based on converting energy during the magnetization and demagnetization of a core, and drawing off additional energy using an additional detachable secondary winding. The additional energy in the invention can be obtained during demagnetization of a core which has been premagnetized ...

The proposed method therefore provides a procedure to test the hypotheses about target source and magnetic field, by verifying these models based on available information or a priori information from geology. We test our methods using synthetic and real data acquired over the Zhangfushan iron-ore deposit and the Yeshan polymetallic deposit in ...

Separation is the main step of ore concentration. Metal recovery and productivity largely depend on the separation process and methods. Based on the physical and chemical properties of ore like its grain size, shape, color, density, friction coefficient, magnetism, moisture and electric property, several process and methods are available.
