(Wichita State University, 2009-12)
Inverse doping pro le 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 ...
• #### 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 ...
• #### Inverse parabolic problems ﻿

(Springer, 2017)
In this chapter, we consider the second-order parabolic equation (9.0.1) a0∂tu − div(a∇u) + b · ∇u + cu = f in Q = Ω × (0, T), where Ω is a bounded domain the space Rn with the C2-smooth boundary ∂Ω. In Section 9.6, we ...
• #### An inverse problem for a dynamical Lamé system with residual stress ﻿

(Society for Industrial and Applied Mathematics, 2007-12-19)
In this paper we prove a Hölder and Lipschitz stability estimates of determining all coefficients of a dynamical Lamé system with residual stress, including the density, Lam´e parameters, and the residual stress, by three ...
• #### Inverse problem for one-dimensional wave equation with matrix potential ﻿

(De Gruyter, 2019-01-20)
We prove a global uniqueness theorem of reconstruction of a matrix-potential a (x, t) {a(x,t)} of one-dimensional wave equation □ u + a u = 0 {\square u+au=0}, x > 0, t > 0 {x>0,t>0}, □ = t 2 - x 2 {\square=\partial-{t}^ ...
• #### Inverse problems ﻿

(Springer, 2017)
In this chapter, we formulate basic inverse problems and indicate their applications. The choice of these problems is not random. We think that it represents their interconnections and some hierarchy.
• #### Inverse source problems without (pseudo) convexity assumptions ﻿

(American Institute of Mathematical Sciences, 2018-08)
We study the inverse source problem for the Helmholtz equation from boundary Cauchy data with multiple wave numbers. The main goal of this paper is to study the uniqueness and increasing stability when the (pseudo)convexity ...
• #### An investigation of capillary surfaces at non-convex corners ﻿

(Wichita State University, 2009-12)
In this thesis we take a close look at the paper CMC Capillary Surfaces at Reentrant Corners  a central feature of which is the question of when does the "central fan" of radial limits exist for a capillary graph in a ...
• #### Investigations in single layer gravitational potential ﻿

(Wichita State University, 2010-05)
• #### Isochrones for old (> 5 GYR) stars and stellar populations. I. models for-2.4 <= [Fe/H] <=+0.6, 0.25 <= Y <= 0.33, and-0.4 <= [alpha/Fe] <=+0.4 ﻿

(IOP Publishing, 2014-10-10)
Canonical grids of stellar evolutionary sequences have been computed for the helium mass-fraction abundances Y = 0.25, 0.29, and 0.33, and for iron abundances that vary from 2.4 to +0.4 (in 0.2 dex increments) when [alpha/Fe] ...
• #### Isolated fixed point sets for holomorphic maps ﻿

(Elsevier SAS, 2006-07)
We study discrete fixed point sets of holomorphic self-maps of complex manifolds. The main attention is focused on the cardinality of this set and its configuration. As a consequence of one of our observations, a bounded ...
• #### Isotonic regression through the Merge and Chop Algorithm for application in statistical inference ﻿

(Wichita State University, 2016-05)
In this paper, the theory for the application of the Merge and Chop Algorithm are defined and proven. The algorithm is used to find isotonic regressions in more situations than comparable methods. A program is included ...
