This paper is in three parts. The first deals with the algebraic and topological structure of spaces of rational transfer function linear systems--ARMAX systems, as they have been called. This ...

We consider the solution of ill-conditioned linear systems using the singular value decomposition, and show how this can improve the accuracy of the computed solution for certain kinds of right-hand ...

Linear motors and ball-screw drives seem to hog the limelight when it comes to linear motion. Rack-and-pinion drives, another type of linear motion device, get no respect. But they are perfectly ...
