haemophilus influenzae, a major cause of meningitis in young children leading to death and other neurological sequelae. the disease leaves 15 to 35% of the survivors with permanent disabilities, such as, mental retardation or deafness. despite the availability of new and more powerful antibiotics children with hib meningitis still suffer from high mortality or morbidity. the emergence of multir...

The method of conjugate gradients provides a very effective way to optimize large, deterministic systems by gradient descent. In its standard form, however, it is not amenable to stochastic approximation of the gradient. Here we explore a number of ways to adopt ideas from conjugate gradient in the stochastic setting, using fast Hessian-vector products to obtain curvature information cheaply. I...

Abstract: The conjugate gradient method is an algorithm for the numerical solution of systems of linear equations whose matrices are positive-definite and symmetric. It is an iterative method that can even be applied to solve a sparse system of equations. In this paper, we applied the conjugate gradient method of higher order to wave propagation control problems. The algorithm of this method wa...

The method of conjugate directions provides a very effective way to optimize large, deterministic systems by gradient descent. In its standard form, however, it is not amenable to stochastic approximation of the gradient. Here we explore ideas from conjugate gradient in the stochastic (online) setting, using fast Hessian-gradient products to set up low-dimensional Krylov subspaces within indivi...

Introduction: The determination of patient’s absorbed dose is the first step of radiation protection which depends on the quantification of organ activity in nuclear medicine. The aim of the present study was to determine the absorbed dose by patient’s uterus following myocardial perfusion scan with 99mTC-sestamibi using Theroluminescnce dosimetry (TLD) and conjugate-view metho...

A Computational Approach to Measuring Homeomorphic Defect by Scott M. LaLonde Master of Science in Mathematics Clarkson University An important concept in the field of dynamical systems is the notion of conjugacy. Two dynamical systems are said to be conjugate if their dynamics are topologically equivalent. In other words, there is a homeomorphism between the underlying spaces which preserves t...
