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 ... -
Numerical modeling and simulations on electro-active polymer flow control
(Rensselaer Polytechnic Institute, Troy, NY, 2012-05) -
Numerical simulation of a single confined microscale impinging jet with conjugate heat transfer effects
(Rensselaer Polytechnic Institute, Troy, NY, 2010-08) -
Numerical study of mechanics of phonation
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)Human phonation is a highly complex process that involves three-way interactions between fluid dynamics of the glottal flow, acoustic waves in the vocal tract, and structural mechanics of the vocal folds. Due to its complex ... -
Obfuscation through the observer-effect : thinking outside the virtual black-box
(Rensselaer Polytechnic Institute, Troy, NY, 2015-05)In this work, we initiate a theoretical study of obfuscation with regards to programs that interact with a user and an environment. We define the System-Interaction model to formally represent this additional dimension of ... -
On the design and implementation of a multi-camera multi-person human tracking system
(Rensselaer Polytechnic Institute, Troy, NY, 2010-05) -
Only everything lasts forever
(Rensselaer Polytechnic Institute, Troy, NY, 2010-05) -
Ontogen : a knowledge-based approach to natural language generation
(Rensselaer Polytechnic Institute, Troy, NY, 2020-08)A long-standing objective of artificial intelligence research has been to build collaborative agents that can communicate with humans via natural language. The fields of artificial intelligence and human-computer interaction ... -
Optical navigation using quadrics and indirect indexing & search methods
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)Autonomy plays a crucial role in navigation to other celestial bodies and around our own planet. With steadily increasing demand for radiometric data on an already strained network, autonomous decision-making is becoming ... -
Optimal scheduling and minimum resource characterization of biochemical analyses on digital microfluidic systems
(Rensselaer Polytechnic Institute, Troy, NY, 2008-08)Digital microfluidic systems (DMFS) are an emerging class of lab-on-a-chip systems that manipulate individual droplets of chemicals on a planar array of electrodes. The biochemical analyses are performed by repeatedly ... -
