Neural network architectures for short text
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)This thesis presents a comparison of four commonly used neural network models for learning to classify and encode short text sequences. We first evaluate the performance of the models for a supervised classification task ... -
Neutronic modeling and analysis of the Transient Reactor Test Facility
(Rensselaer Polytechnic Institute, Troy, NY, 2015-12)The Transient Reactor Test Facility is a nuclear research reactor operated by the Idaho National Laboratory. It was used for the testing of nuclear reactor fuels and materials from 1959 until 1994. It has remained inactive ... -
New approaches to efficient structural analysis of social and biological networks
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)Network science is a discipline within the larger area of computer science that studies complex networks using the methodologies of graph theory, statistical analysis, and data visualization. As more and more data are made ... -
New methods for forecasting the Cox process
(Rensselaer Polytechnic Institute, Troy, NY, 2012-05) -
NMR structural studies of FAD mutations in APPTM and amyloid-β peptide
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)Aβ protein is the main aggregate component found in senile plaque in the AD brain. Familial Alzheimer’s disease (FAD) point mutations found within the Aβ sequence are known to cause early onset AD that occurs prior to the ... -
Noise reduction in user generated datasets
(Rensselaer Polytechnic Institute, Troy, NY, 2014-08)The effect of modeling data noise using the Inverse Gaussian Distribution is twofold: first, Normally distributed and Gaussian predicated statistical methods for mining, measuring and analyzing data become less effective, ... -
Non-canonical cell stress in osteogenesis imperfecta
(Rensselaer Polytechnic Institute, Troy, NY, 2021-05)We used this model to demonstrate noncanonical quality control of PC1 folding. Like other secretory proteins, PC1 misfolds and accumulates in the lumen of endoplasmic reticulum (ER), disrupting the function of this crucial ... -
Non-destructive platform for morphologic and cell density characterization of developing and drugged multicellular tumor spheroids
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)In vitro tumor models are important tools for exploring cancer progression and novel therapeutic strategies. These models are often oversimplified and lack many features of the 3D tumor environment, limiting their ability ... -
Non-discriminative algorithmic pricing: decentralized resource allocation in markets
(Rensselaer Polytechnic Institute, Troy, NY, 2017-05)2) Pricing under uncertainty: Even when the seller only has access to a distribution over (submodular) buyer valuations, and items have a non-linear production cost, we show that it is possible to efficiently compute prices ... -
Non-equilibrium molecular simulations of simple fluid transport at fluid-solid interfaces and fluidic behaviors at nanoscale
(Rensselaer Polytechnic Institute, Troy, NY, 2012-05) -
Non-stationarity dynamics of asset comovement
(Rensselaer Polytechnic Institute, Troy, NY, 2016-12)In this dissertation, we contribute to the risk and asset pricing literature by investigating causes and effects of non-stationarity of financial time series. We propose a network-based framework to analyze structural and ... -
Nonconvex regularizers for sparse optimization and rank minimization
(Rensselaer Polytechnic Institute, Troy, NY, 2021-05)This dissertation addresses the problem of minimizing a nonconvex relaxation to the rank of a matrix. In the first of three works presented in this dissertation, we present the problem of rank minimization as a semidefinite ... -
Novel high refractive index, thermally conductive additives for high brightness white LEDs
(Rensselaer Polytechnic Institute, Troy, NY, 2015-08)These experiments were originally conducted on the commercially available methylated Sylgard 184 silicone and then again on a higher refractive index methyl-phenyl silicone from Momentive. While some of the results from ... -
Novel residual-based large eddy simulation turbulence models for incompressible magnetohydrodynamics
(Rensselaer Polytechnic Institute, Troy, NY, 2013-08)The goal of this work was to develop, introduce, and test a promising computational paradigm for the development of turbulence models for incompressible magnetohydrodynamics (MHD). MHD governs the behavior of an electrically ... -
Nucleolin-G-quadruplex interactions, with an emphasis on genome derived sequences
(Rensselaer Polytechnic Institute, Troy, NY, 2017-05)The discovery of new DNA aptamers is an arduous process. The primary approach is the Systematic Evolution of Ligands by Exponential Enrichment (SELEX), where many different DNA sequences are screened against a specific ... -
Numerical methods for fluid-structure interaction and free surface flows
(Rensselaer Polytechnic Institute, Troy, NY, 2019-05)In the final part of this thesis, an algorithm is developed for free surface flows driven by gravity and surface tension. Deforming composite grids are used to handle the motion of the free surface and the governing equations ... -
Numerical methods for the simulation of reactive and non-reactive compressible flow for materials with general equations of state
(Rensselaer Polytechnic Institute, Troy, NY, 2020-08)In the second part of this thesis a model for multi-material flow is described, again assuming general equations of state of Mie-Gr\"uneisen form for the constituents. A corresponding high-resolution quasi-conservative ... -
