The syntheses of a cobalt(III) complex, 2, containing N-(2-pyridylmethyl)urea and of six complexes, 3, containing phenyl-substituted N-2-pyridylmethyl-N'-(X)phenylureas (where X = 4-H, 4-CH(3), 4-Br, 3-Cl, 4-CF(3), and 4-NO(2)), have been accomplishe

For a fixed tuple of square matrices X ={X_1,...,X_g} the set I(X) of all noncommutative polynomials p in X and Xâ such that p(X) = 0 is an ideal in the â-algebra of all polynomials. This article concerns such zeroes and their corresponding

The purpose of this paper is to present some preliminary results on the stability of the information state system. The information state system underlies the (infinite dimensional) dynamics of an H ∞ controller for a nonlinear system. Thus it is im

We present algorithms for solving general sup-norm minimization problems over spaces of analytic functions, such as those arising inH∞ control. We also give an analysis and some theory of these algorithms. Part of this is specific to analytic optim

We compared patients with small bowel obstruction (SBO) admitted through the emergency department to the surgical service (SS) with those admitted to the medical service (MS) with respect to outcomes and healthcare cost. We conducted a retrospective

In this paper, the practical existence of ideal MHD equilibria is investigated for various Tokamak designs. It is known from past experiment that, with increasing poloidal field-shaping coil distance, with increasing plasma elongation and with more s

We propose and analyse a method of estimating the poles near the unit circleT of a functionG whose values are given at a grid of points onT: we give an algorithm for performing this estimation and prove a convergence theorem. The method is to identif
