In the context of quantum physics, the term "duality" refers to transformations that link apparently distinct physical ...

The kind of thinking that built empires and assembly lines—that beautifully predictable, step-by-step, linear logic—is ...

Abstract: This letter investigates the problem of simultaneous state and unknown input estimation in a nonlinear system within multi-sensor networks. To avoid the linearization errors caused by ...

differential-algebraic equation (DAE) systems, and nonlinear algebraic systems: Warning to users who receive more than one of the individual packages at different times: Mixing old and new versions of ...

A basic Newton-Raphson type nonlinear equation solver for sparse or dense systems with m functions of n input variables. A work in progress. Is object-oriented. Works with square, under-determined, or ...

This equation plays a significant role in non-linear fiber optics. It also has many important applications in photonic crystal fibers. To this end, firstly, we obtain some novel optical solutions of ...
