We show that in the limit that the bulk physics decouples, these theories become equivalent to theories with a flat and non-compact transverse space. We present a matrix model description of the type IIA theory on $\IR^9\times S^1$ with NS five-branes located at points on the circle. Consequently, we obtain a description of the dual configuration of Kaluza-Klein monopoles in the type IIB theory.14 pagesHigh Energy Physics - Theorytext
