Shader sign function is broken when values of 0 are present.

Sign function is supposed to return 1 or -1 depending if the given value is positive or negative. Seems like the sign function does not contain logic to handle values that are exactly 0, so the result ...

Avoid applying the sign() function to event indicator functions

I am working with some colleagues on an innovative application of FMU, namely analyzing the stability of periodic orbits of switching electronic circuits. The analysis requires the formuation of the ...

Anti-Windup Digital Control Design for Time-Delayed Analog Nonlinear Systems Using Approximated Scalar Sign Function

This paper describes an approximated-scalar-sign-function-based anti-windup digital control design for analog nonlinear systems subject to input constraints. As input saturation occurs, the non-smooth ...
