In vivo nuclear magnetic resonance (NMR) spectroscopy is a particularly powerful technique, since it allows samples to be analyzed in their natural, unaltered state, criteria paramount for living ...

A branch flow model (BFM) is used to formulate the AC power flow in general networks. For each branch/line, the BFM contains a nonconvex quadratic equality. A mathematical formulation of its convex ...

Extended Smith chart concept is proposed to enable advanced graphical interpretation of devices containing complex properties. This methodology is based on the Smith chart concept, and makes it easy ...
