Monomial resolutions for efficient computation of simplicial homology

, 2019
We propose algorithms based on monomial resolution theory for simplicial homology computation. We explore some alternatives that can either be used as a preprocessing step for homology computation or as alternatives to the usual linear algebra approach ...

Symbolic Computation in System Simulation and Design

, 1995
This paper examines some of the roles that symbolic computation plays in assisting system-level simulation and design. By symbolic computation, we mean programs like Mathematica that perform symbolic algebra and apply transformation rules based on ...

On the Use of Resultant-Based Frequency-Sweeping Approaches to Construct Stability Charts for Systems With Two Delays

IEEE Access
The resultant-based frequency-sweeping approach is appealing for creating a stability map to study stability robustness against delay uncertainties. It relies on converting the system’s transcendental characteristic function into a polynomial form
