Biologically motivated quantum neural networks
(IEEE, 2017)This paper presents one step toward creating the building blocks for machine intelligence that is inspired by its biological equivalent. The authors' quantum learning methods (deep quantum learning) are applied to quantum ... -
The Carleman formula and recovering the refractive index of the two-dimensional Helmholtz equation
(2008)We consider the Cauchy problem for the Helmholtz equation with given bounded refrac- tive index in an arbitrary planar domain with Cauchy data only on part of the boundary of the domain. We derive a Carleman-type formula ... -
Combinatorial input recognition algorithm Internet applications to HTTP web servers
(Wichita State University. Graduate School., 2007-04-27)We introduce an algorithm for the classical recognition problem of identifying elements s within a class of strings S = {s1, s2, ..., sn}. Here it is assumed that struct s = { char *a; int z; }; and that for two strings ... -
Constrained pole placement by linear quadratic modification
(IEEE, 1991-06-26)A noniterative method is introduced that will enable the designer to find an optmal one step state feedback controller. The controller will place the eigenvalues of the closed loop system in a specified disk. -
Extending the piecewise exponential estimator of the survival function
(Wichita State University. Graduate School., 2008-04-25)We propose a new way of extending the piecewise exponential estimator (PEXE) beyond the last observation, where the original PEXE and the Kaplan-Meier estimator (KME) of the true survival function (SF) are undefined. ... -
A Fornberg-like method for the numerical conformal mapping of bounded multiply connected domains
(Wichita State University. Graduate School, 2010-04-23)A new Fornberg-like method is presented for computing conformal maps from the interior of the unit disk with m>1 circular holes to the interior of a smooth closed curve with m holes bounded by smooth curves. The method is ... -
Forty-fold speedup of NV- center magnetometry with sequential Bayesian experiment design
(Optica Publishing Group, 2021-05-01)In magnetometry using quantum defects in diamond (NV - centers), we demonstrate forty-fold speedup with sequential Bayesian experiment design as compared with conventional NV-magnetometry using frequency-swept measurements -
Forty-fold speedup of NV- center magnetometry with sequential Bayesian experiment design
(IEEE, 2021-05-01)In magnetometry using quantum defects in diamond (NV - centers), we demonstrate forty-fold speedup with sequential Bayesian experiment design as compared with conventional NV-magnetometry using frequency-swept measurements. -
Horizontal bundles and connections
(Wichita State University. Graduate School, 2014-04-25)A manifold is a mathematical space that locally resembles standard Euclidean space. In order to study the geometry of such a space, it is necessary to prescribe a connection on the manifold. A connection describes how ... -

Inverse doping profile analysis for semiconductor quality control
(Wichita State University. Graduate School, 2010-04-23)Inverse doping profile problems are linked to inverse conductivity problems under the assumptions of zero space charge and low injection. Unipolar inverse conductivity problems are analyzed theoretically via three uniqueness ... -
Machine learning applied to programming quantum computers
(American Institute of Aeronautics and Astronautics, 2019-01-06)We apply machine learning to “program” quantum computers, both in simulation and in experimental hardware. A major difficulty in quantum computing is developing effective algorithms that can be programmed on a quantum ... -
Models of parenting and its effect on academic productivity: Preliminary results from an international survey
(International Conference on Scientometrics and Informetrics, 2019-09)This preliminary paper investigates the cost of parenting engagement on academic productivity and impact. Instead of investigating the relationship between gender and academia, this study focuses on time invested in parenting ... -
Multivariate isotonic regression and its algorithms
(Wichita State University. Graduate School, 2009-05-01)We use regression functions, which are the means of random variables, to interpret statistical inference. Often an order is imposed on the values of the regression function. Thus, we refer to the regression as an order ... -
Numerical comparison of negative damping bounds in a specified domain when the wave speed varies
(IEEE, 1992-06-24)The energy decay of a self-excited wave equation utt - c2 ¿ u - P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) ¿ 0, and P(x) L¿(¿), ¿ ¿ ¿ Rn. Moreover, the relationship between two bounds for ... -
Numerical methods for Riemann-Hilbert problems in multiply connected circle domains
(Elsevier Science Inc., 2016-12-01)Riemann-Hilbert problems in multiply connected domains arise in a number of applications, such as the computation of conformal maps. As an example here, we consider a linear problem for computing the conformal map from the ... -
On the inverse source problem with boundary data at many wave numbers
(Springer, 2020-02-04)We review recent results on inverse source problems for the Helmholtz type equations from boundary measurements at multiple wave numbers combined with new results including uniqueness of obstacles. We consider general ... -
Pellet ablation in tokamak reactors
(Wichita State University. Graduate School., 2012-04-18)Injecting frozen hydrogen pellets has been proposed as a method of efficiently refueling Tokamak fusion reactors. The intense heat of the reactor causes the pellet to lose mass in a process called ablation. This process ... -
Pole placement by linear quadratic modification for continuous time systems
(IEEE, 1991-06-26)This paper bridges the gap between linear quadratic solution and pole placement providing a simple criterion sucht that the resulting optimal gain places the closed loop eigenvalues at desired locations. The method has the ...
