A Unified Derivation of Operational Matrices for Integration in Systems Analysis
Using the operational matrix of an orthogonal function to perform integration for solving, identifying and optimizing a linear dynamic system has several advantages: (1) the metho...

Hyperexponential solutions of finite-rank ideals in orthogonal ore rings
An orthogonal Ore ring is an abstraction of common properties of linear partial differential, shift and q-shift operators. Using orthogonal Ore rings, we present an algorithm for...

Efficient solution of systems of orientation constraints
One subtask in constraint-driven placement is enforcing a set of orientation constraints on the devices being placed. Such constraints are created in order to, for example, implem...
