β¦ Synopsis
Bongiorno and Lu have presented a condition for the stabilizability using stable controllers of an unstable plant. We show this condition may be reformulated in terms of Cauchy indices, allowing its checking in a finite number of rational operations, should the plant not be given in factored form, i.e. should its poles and zeros be unknown. The results applies to discrete and continuous-time, and scalar and multivariable plants.

The condition numbers described by Stewart, Todd, and others for a matrix A are given by the suprema of the norms of all the oblique projection operators respectively on the image space of AT and the null space of A. This paper shows that these two numbers coincide.
The boundary condition, zero solids pressure at the top of a particle bed of maximum spoutable height, H m , is shown to eliminate any resort to empiricism in the derivation of the fluid velocity in the annulus of a spouted bed for which both viscous and inertial effects are taken into account. The
