• #### A large-scale trust-region approach to the regularization of discrete ill-posed problems ﻿

(1999)
We consider the problem of computing the solution of large-scale discrete ill-posed problems when there is noise in the data. These problems arise in important areas such as seismic inversion, medical imaging and signal ...
• #### A minimum-cost-neighbor multicast routing protocol for mobile wireless ad hoc networks ﻿

(2010)
MiCoN (Minimum-Cost Neighbor) is a new on-demand multicast routing protocol for mobile wireless ad hoc networks. Multicast routing in MiCoN is based on a new multi-route unicast routing protocol for maintaining routes ...
• #### A modified augmented Lagrangian merit function, and Q-superlinear characterization results for primal-dual Quasi-Newton interior-point method for nonlinear programming ﻿

(1997)
Two classes of primal-dual interior-point methods for nonlinear programming are studied. The first class corresponds to a path-following Newton method formulated in terms of the nonnegative variables rather than all primal ...

(1977)
• #### A multi-faceted model of the consequences of sample size choice in usability testing ﻿

(2008)
A multi-faceted model is developed to demonstrate the consequences of sample size choice in usability testing. This model takes into account the severity levels of user performance, the distribution of severity levels, the ...
• #### A new approach to slant stack processing: An X-window (OSF/motif) project ﻿

(1992)
A new definition for slant stack and inversion has been formulated. The different p ranges with different frequencies in the forward slant stack provide accurate reconstruction of the original data. The computing time is ...
• #### A pedagogic programming environment for Java that scales to production programming ﻿

(2003)
This thesis describes extensions to the DrJava development environment that make it suitable for production programming. DrJava is an effective tool for teaching introductory programming skills in Java, and its simplicity ...
• #### A practical application of a force feedback control system for a mechanical, 3-fingered, dextrous hand ﻿

(1992)
The trajectory planning and control system for a mechanical, 3-fingered, dextrous hand are analyzed and implemented. The forward and inverse kinematics of the fingers are derived and used to analyze the capabilities of the ...
• #### A qualitative theory of gas dynamics ﻿

(1992)
Within the realm of research toward the emulation of human intelligence, the problem of how to perform qualitative reasoning with computer programs has received considerable attention. The research field of qualitative ...
• #### A Scalable Locality-aware Adaptive Work-stealing Scheduler for Multi-core Task Parallelism ﻿

(2011)
Recent trend has made it clear that the processor makers are committed to the multicore chip designs. The number of cores per chip is increasing, while there is little or no increase in the clock speed. This parallelism ...
• #### A scattered data approximation tool to map carbon nanotube dispersion to the processing parameters in polymer nanocomposites ﻿

(2009)
The relationship of nanocomposite dispersion was studied with the variation of dispersion techniques and other processing parameters. Examining all permutations of the various factors in the laboratory is a challenging ...
• #### A Sequence-Based, Population Genetic Model of Regulatory Pathway Evolution ﻿

(2011)
Complex phenotypes with genetic cause are understood through many processes, including regulatory pathways, but our evolutionary understanding of these critical structures is undermined by poor models which fail to preserve ...
• #### A SINGLE INTERMEDIATE LANGUAGE FOR PROGRAMMING ENVIRONMENTS ﻿

(1985)
Programming by the traditional methods of text editing and batch compilation is no longer necessary. The advent of the personal workstation and bitmap graphics allows us to construct integrated programming environments, ...
• #### A software simulation testbed for CDMA wireless communication systems ﻿

(1999)
This thesis develops a software wireless communication testbed which simulates a Code Division Multiple Access (CDMA) link. CDMA is a popular technology in cellular systems due to its superior capacity and performance. The ...
• #### A storage architecture for data-intensive computing ﻿

(2010)
The assimilation of computing into our daily lives is enabling the generation of data at unprecedented rates. In 2008, IDC estimated that the "digital universe" contained 486 exabytes of data [9]. The computing industry ...

(1973)
• #### A study of viscous effects in seismic modeling, imaging, and inversion: Methodology, computational aspects, and sensitivity ﻿

(1996)
Real Earth media are anelastic, which affects both the kinematics and dynamics of propagating waves: Waves are attenuated and dispersed. If anelastic effects are neglected, inversion and migration can yield erroneous ...
• #### A subgradient algorithm for nonlinear integer programming and its parallel implementation ﻿

(1991)
This work concerns efficiently solving a class of nonlinear integer programming problems: min $\{f(x)$: $x \in \{0,1\}\sp{n}\}$ where $f(x)$ is a general nonlinear function. The notion of subgradient for the objective ...
• #### A symmetry preserving singular value decomposition ﻿

(2007)
This thesis concentrates on the development, analysis, implementation, and application of a symmetry preserving singular value decomposition (SPSVD). This new factorization enhances the singular value decomposition (SVD)---a ...
• #### A systolic VLSI architecture for complex SVD ﻿

(1991)
This thesis presents a systolic algorithm for the SVD of arbitrary complex matrices, based on the cyclic Jacobi method with "parallel ordering". As a basic step in the algorithm, a two-step, two-sided unitary transformation ...
