Fast Hybrid Solution of Algebraic Systems

We propose and analyze the error and timing of solvers consisting of both analog and digital circuitry for sparse linear systems of equations. We obtain high speed, but low precision from the analog circuits. We combine this with low speed, but high precision from the digital circuits. The hybrid circuit should be faster than digital circuits alone. As a preconditioner to standard iterative sol...

Finding Semi-Analytic Solutions of Power System Differential-Algebraic Equations for Fast Transient Stability Simulation

 Abstract— This paper studies the semi-analytic solution (SAS) of a power system’s differential-algebraic equation. A SAS is a closed-form function of symbolic variables including time, the initial state and the parameters on system operating conditions, and hence able to directly give trajectories on system state variables, which are accurate for at least a certain time window. A two-stage SA...

High Speed Transient Stability - A Multiprocessing Solution

This paper presents a method for solving power system transient stability problem by multiprocessing computing. A new algorithm based on system splitting, partitioning and Wmatrix techniques has been developed and implemented in the High Speed Transient Stability (HSTS) program. This program has embedded parallelism and can be executed on various platforms of parallel and distributed processing...

TWLT 21 Algebraic Methods in Language Processing

Issues of representation arise in natural language processing, user interface design, art, and indeed, communication with any medium. This paper addresses such issues using algebraic semiotics, which draws on algebraic specification to give (among other things) an algebraic theory of representation, and a generalization of blending in the sense of cognitive linguistics. New ideas in this paper ...
