Angles-Only Initial Orbit Determination via Multivariate Gaussian Process Regression Open

David J. Schwab, Puneet Singla, Sean M. O’Rourke · 2022

Vital for Space Situational Awareness, Initial Orbit Determination (IOD) may be used to initialize object tracking and associate observations with a tracked satellite. Classical IOD algorithms provide only a point solution and are sensitiv…

Covariance-Generalized Matching Component Analysis for Data Fusion and Transfer Learning Open

Nick Lorenzo, Sean M. O’Rourke, Theresa Scarnati · 2021

In order to encode additional statistical information in data fusion and transfer learning applications, we introduce a generalized covariance constraint for the matching component analysis (MCA) transfer learning technique. We provide a c…

In order to encode additional statistical information in data fusion and\ntransfer learning applications, we introduce a generalized covariance\nconstraint for the matching component analysis (MCA) transfer learning\ntechnique. We provide …

SIAM-REID: confuser-aware Siamese tracker with re-identification feature Open

Abu Md Niamul Taufique, Andreas Savakis, Michael Braun, Daniel Kubacki, Ethan Dell , et al. · 2021

Siamese deep-network trackers have received significant attention in recent years due to their real-time speed and state-of-the-art performance. However, Siamese trackers suffer from similar looking confusers, that are prevalent in aerial …

Random perturbation and matrix sparsification and completion. Open

Sean M. O’Rourke, Van Vu, Ke Wang · 2018

We discuss general perturbation inequalities when the perturbation is random. As applications, we obtain several new results concerning two important problems: matrix sparsification and matrix completion.

Constrained Least Squares, SDP, and QCQP Perspectives on Joint Biconvex\n Radar Receiver and Waveform design Open

Pawan Setlur, Sean M. O’Rourke, Muralidhar Rangaswamy · 2018

Joint radar receive filter and waveform design is non-convex, but is\nindividually convex for a fixed receiver filter while optimizing the waveform,\nand vice versa. Such classes of problems are fre- quently encountered in\noptimization, a…

On Convex Relaxations for Joint Transmit-Receive Design in Radar Systems Open

Sean M. O’Rourke · 2018

This dissertation investigates joint design of transmit and receive resources in radar systems, given prior knowledge of a signal-dependent clutter environment, based on simultaneous convex relaxation. Motivated by waveform-adaptive space-…

Genomics clarifies taxonomic boundaries in a difficult species complex Open

Jason Baumsteiger, Peter B. Moyle, Andres Aguilar, Sean M. O’Rourke, Michael R. Miller · 2017

Efforts to taxonomically delineate species are often confounded with conflicting information and subjective interpretation. Advances in genomic methods have resulted in a new approach to taxonomic identification that stands to greatly redu…

Relaxed Biquadratic Optimization for Joint Filter-Signal Design in Signal-Dependent STAP Open

Sean M. O’Rourke, Pawan Setlur, Muralidhar Rangaswamy, A. Lee Swindlehurst · 2017

We investigate an alternative solution method to the joint signal-beamformer\noptimization problem considered by Setlur and Rangaswamy[1]. First, we directly\ndemonstrate that the problem, which minimizes the received noise, interference,\…

Whole-Genome Sequencing and Concordance Between Antimicrobial Susceptibility Genotypes and Phenotypes of Bacterial Isolates Associated with Bovine Respiratory Disease Open

Joseph R. Owen, Noelle Noyes, Amy Young, Daniel J. Prince, Patricia C. Blanchard , et al. · 2017

Extended laboratory culture and antimicrobial susceptibility testing timelines hinder rapid species identification and susceptibility profiling of bacterial pathogens associated with bovine respiratory disease, the most prevalent cause of …

Constrained Least Squares, SDP, and QCQP Perspectives on Joint Biconvex Radar Receiver and Waveform design Open

Pawan Setlur, Sean M. O’Rourke, Muralidhar Rangaswamy · 2017

Joint radar receive filter and waveform design is non-convex, but is individually convex for a fixed receiver filter while optimizing the waveform, and vice versa. Such classes of problems are fre- quently encountered in optimization, and …

RAD Capture (Rapture): Flexible and Efficient Sequence-Based Genotyping Open

Omar A. Ali, Sean M. O’Rourke, Stephen J. Amish, Mariah H. Meek, Gordon Luikart , et al. · 2015

Massively parallel sequencing has revolutionized many areas of biology, but sequencing large amounts of DNA in many individuals is cost-prohibitive and unnecessary for many studies. Genomic complexity reduction techniques such as sequence …
