• #### A SNP Calling And Genotyping Method For Single-cell Sequencing Data ﻿

(2015-04-23)
In this thesis, we propose a single nucleotide polymorphism (SNP) calling and genotyping algorithm for single-cell sequencing data generated by the recently developed single-cell sequencing (SCS) technologies. SCS methods ...
• #### 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 Spectral Decomposition Heuristic for Near Optimal Capture Sets In Consensus Models ﻿

(2016-08-31)
Given a network G=(V,E), consider the problem of selecting a subset of nodes, A, of a fixed size, k, such that the sum expected walk length from V to A, or hitting time, is minimized. This study is motivated by modeling ...
• #### A spectral encoding system based on planar waveguide integrated optics ﻿

(2001)
The need for bandwidth at the access level has driven the development of many new multiple access schemes. This paper explores a spectral encoding scheme for Optical CDMA, in which bipolar communication is accomplished by ...
• #### A SPECTROPHOTOMETRIC STUDY OF HYDROGEN II REGIONS IN CHEMICALLY YOUNG GALAXIES ﻿

(1981)
The results of an investigation of the optical spectra of thirty-four emission nebulae in thirteen irregular and late-type spiral galaxies are presented. The program galaxies, with the number of nebulae observed in each ...
• #### A Spectrum-based Regularization Approach to Linear Inverse Problems: Models, Learned Parameters and Algorithms ﻿

(2015-04-20)
In this thesis, we study the problem of recovering signals, in particular images, that approximately satisfy severely ill-conditioned or underdetermined linear systems. For example, such a linear system may represent a set ...
• #### A SPIN-POLARIZED LOW-ENERGY ELECTRON DIFFRACTION STUDY OF A MAGNETIZED NICKEL(111) SURFACE ﻿

(1987)
Spin-polarized low energy electrons from a GaAs source were used to probe magnetized nickel(111) surface. Intensity curves as well as spin-orbit and exchange induced polarization asymmetries were obtained for the ...
• #### A statistical investigation of ozone exposure assessment by direct and indirect measurement ﻿

(1998)
Recent studies have proposed the application of exposure-based criteria in developing alternative primary ambient ozone standards. Historically, epidemiological studies of ozone have approached exposure assessment in a ...
• #### A STATISTICAL INVESTIGATION OF THE PULMONARY EFFECTS OF EXPOSURE TO ASBESTOS ﻿

(1981)
In this study, data collected on a group of 1112 workers formerly employed in the production of insulation containing amosite asbestos at a plant in Tyler, Texas are examined and a subset of continuously employed workers ...
• #### A steady state flow/field model of solar wind interaction with Mars ﻿

(1989)
A steady state flow/field model is applied to the direct interaction of the solar wind with the Martian ionosphere. We have coupled observational data with the kinetic theory plasma equations within a single self-consistent ...
• #### A stereocontrolled total synthesis of (+,-)-renieramycin A ﻿

(1992)
A novel synthetic route via iterative condensations of piperazinedione and substituted benzaldehydes has resulted in the first total synthesis of the complex antibiotic, renieramycin A 1a. Salient features include an ...
• #### A stochastic approach for estimating fatigue life of equipment located at topside of FPSO offshore systems ﻿

(2002)
Floating Production, Storage and Offloading (FPSO) Systems are subjected to stochastic wave loads. In this context, an approach for stochastic fatigue analysis of FPSO topside equipment is developed. Proper FPSO transfer ...
• #### A stochastic approach to motorcycle dynamics ﻿

(2009)
A study on the applicability of the Monte Carlo method in the analysis of the dynamical behavior of motorcycles subject to road excitation is presented. To this end, a time-domain numerical simulation of the response of a ...
• #### A stochastic approach to prepayment modeling ﻿

(1996)
A new type of prepayment model for use in the valuation of mortgage-backed securities is presented. The model is based on a simple axiomatic characterization of the prepayment decision by the individual in terms of a ...
• #### A stochastic model for calculating collisional ionization rates in dense plasmas ﻿

(1993)
A formalism has been developed here in which the collisional ionization rate is determined directly, as a probability of transition due to changes in the plasma's local electric field. The calculations described here are ...
• #### 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 ...
• #### A strategy to apply quantitative epistasis analysis on developmental traits ﻿

(2017-05-15)
Abstract Background Genetic interactions are keys to understand complex traits and evolution. Epistasis analysis is an effective method to map genetic interactions. Large-scale ...
• #### A stratigraphic analysis of Paleogene deposition in northwest Europe and the role of graphic correlation in sequence stratigraphy ﻿

(1994)
A sequence stratigraphic analysis of Paleogene deposits, using subsurface data (well logs, seismic data, and biostratigraphy) from the Central North Sea and published outcrop information from northwest Europe, has documented ...
• #### A structural analysis of Al(3)Ti and Al(3)Ti-Nb titanium trialuminides by XRD and EXAFS ﻿

(1997)
In an effort to expand the composition range over which Al$\sb3$Ti is stable, various amounts of niobium were substituted for titanium and processed by melt-spinning. In order to characterize $\rm Al\sb3Ti\sb{x}Nb\sb{y},$ ...
• #### A structural analysis of Gellert's novel Leben der Schwedischen Graefin von G ﻿

(1970)
Structural elements of Gellert's novel, such as the choice of a narrator, the use of letters and dialog, contribute to a system of abstractions which pervades the work. As a predominantly didactic writer Gellert was ...
