Magnetic flux leakage (MFL) detection methods are widely used to detect pipeline defects. However, it is limited by the orientation and magnetization. Besides, bulky excitation systems incapable of adapting complex environments. This article proposes a new electromagnetic structured coupling sensing merging alternating current field measurement MFL within multiparameter system for different typ...

In this article we study the smoothness properties of solutions to a two-dimensional coupled Zakharov-Kuznetsov system. We show that equations dispersive nature leads gain in regularity for solution. particular, if initial data (u0,v0) possesses certain and sufficient decay as x → ∞, then solution (u(t),v(t)) will be smoother than (u0, v0) 0 < t ≤ T where is existence time

Cortex is an automatic generic document summarization system. To select the most relevant sentences of a document, it uses an optimal decision algorithm that combines several metrics. The metrics processes, weighting and extract pertinence sentences by statistical and informational algorithms. This technique might improve a QuestionAnswering system, whose function is to provide an exact answer ...
