A Numerical Conformal Mapping Method and the Poisson Equation on Irregular Domains
In this thesis, we propose a numerical conformal mapping procedure for constructing the unique transformation that maps a unit disk onto a simply connected irregular region. All the systems of linear equations that arise in formulating the method, are solved using Rapid Elliptic Solvers. Therefore, …

Loosely coupled LiDAR-Visual/Thermal-Inertial Odometry and Mapping
… LiDAR-Visual/Thermal-Inertial odometry and mapping method that uses factor graphs. Our approach jointly optimizes relative pose constraints provided by a LiDAR scan-to-scan alignment method and a Visual/Thermal-Inertial method with preintegrated IMU constraints. An optimized relative pose …

Operations improvements through non=value-added step reduction
… how factories can use the Value Stream Mapping method to reduce both direct and indirect labor cost components through a non-value-added step reduction. The principal objective of this internship was to identify instances of non-value-added work in a product value stream and implement …

Persistent autonomous exploration, mapping and localization
In this thesis, we investigate methods for exploration, persistent autonomy, and simultaneous localization and mapping tasks for an autonomous mobile robot with battery constraints. First, we present modifications to baseline frontier exploration on an occupancy grid that makes the robot's frontier …

Allele-Specic QTL fine-mapping with PLASMA
We introduce PLASMA (PopuLation Allele-Specic MApping), a statistical ne- mapping method that leverages allele-specic (AS) genomic data to improve detection of quantitative trait loci (QTLs) with causal effects on molecular traits. In simulations, PLASMA accurately prioritizes causal QTL variants …

Hydrodynamic and morphodynamic responses to surfzone seafloor perturbations
… temporal resolution of bathymetric estimates, a mapping method was developed to combine infrequent, spatially dense watercraft surveys with continuous, spatially sparse in situ altimeter estimates of the seafloor location. In another set of seafloor perturbation experiments, channels were dredged …

Product perceptual mapping on fashion designs with Gaussian mixture variational autoencoder and triplet loss
… into a market. Conventional product perceptual mapping methods exhibit limitations, particularly in capturing the highly nonlinear structure in product perceptual categories. Therefore, given only a set of images and triplet data representing product co-occurence by consumers, we propose and use …

Deep Embedding Kernel
Kernel methods and deep learning are two major branches of machine learning that have achieved numerous successes in both analytics and artificial intelligence. While having their own unique characteristics, both branches work through mapping data to a feature space that is supposedly more …
