Abstract: A classical result in linear system theory is that a causal linear time-varying (LTV) system has a smooth finite dimensional realization if and only if its impulse response exhibits a ...

Abstract: Absolute efficiency measurements in power drive systems (PDSs) require low-uncertainty instrumentation, making them costly and impractical for properly characterizing small incremental ...

A Russian mathematician has developed a new method for analyzing a class of equations that underpin models in physics and economics and are considered "eternal" as they have challenged researchers for ...
