Quantifying the degradation of automatic speech recognition for reverberant environments
(Rensselaer Polytechnic Institute, Troy, NY, 2008-08)In general, automatic speech recognition (ASR) algorithms are designed for use with pure, anechoic signals. Although ASR systems approach a human’s intelligibility for clean signals, it is well acknowledged that a downfall ... -
Quantitative optical elasticity imaging for biomechanics
(Rensselaer Polytechnic Institute, Troy, NY, 2019-08)The field of elasticity imaging, or elastography, has undergone rapid development over the last three decades, evolving from using ultrasound for simple qualitative measurements of tissue stiffness to characterizing a wide ... -
Quantitative understandings of human in vitro drug response relationships to in vivo model systems
(Rensselaer Polytechnic Institute, Troy, NY, 2019-12)Drug development is inefficient and expensive, with less than 10% of drug candidates entering clinical trials proceeding to market, and each costing an estimated $2.5 billion. This inefficiency is due to several reasons, ... -
Quasi-static rotor morphing applications in flight mechanics and active track-and-balance
(Rensselaer Polytechnic Institute, Troy, NY, 2018-08)Conventional rotorcraft generally operate with a fixed-geometry rotor and perform sub-optimally over the flight envelope. Rotor morphing, as a concept, allows planform variation that can overcome this limitation to improve ... -
Question answering and generation from structured and unstructured data
(Rensselaer Polytechnic Institute, Troy, NY, 2020-08)This dissertation focuses on two different but related natural language processing problems, namely, question answering and question generation. Automated question answering (QA) is the process of finding answers to natural ... -
Radical game design

Random projections for support vector machines
(Rensselaer Polytechnic Institute, Troy, NY, 2012-12)Let X ∈ R n×d be a data matrix of rank ρ, representing n points in R d . The linear support vector machine constructs a hyperplane separator that maximizes the 1-norm soft margin. We develop a new oblivious dimension ... -
Randomized algorithms for mining massive matrices: design & implementation at terascale and beyond
(Rensselaer Polytechnic Institute, Troy, NY, 2018-05)Modern technological advancements and innovation has led to an explosive growth of data in various domains, ranging from physics and biological sciences to economics and social sciences. Research on mathematical libraries ... -
Randomness mergers: combining the quantum and classical worlds
(Rensselaer Polytechnic Institute, Troy, NY, 2016-12)In an ever-evolving digital world, the onset of the Internet of Things leads to a new problem in secure communications. Embedded devices may lack the computational power to generate high entropy random numbers for cryptographic ... -
Range data analysis by free-space modeling and tensor voting

Rate dependence of CaF2 nanorod growth on amorphous substrates
(Rensselaer Polytechnic Institute, Troy, NY, 2011-05) -
Real-time address leak detection on the DynamoRIO platform using dynamic taint analysis
(Rensselaer Polytechnic Institute, Troy, NY, 2018-05)Address Space Layout Randomization, or ASLR, has long since served as one of the most effective deterrents to successful and, in particular, reliable exploits. However, a successful exploit may bypass ASLR by employing ... -
Real-time recognition of piano performance for controlling variable acoustic systems
(Rensselaer Polytechnic Institute, Troy, NY, 2018-08)With the increasing popularity of multi-use performance halls, variable acoustic systems are in high demand. User interfaces with presets are often used to switch between various acoustical settings in which users select ... -
Reason and rationality in nuclear deterrence : implementing an approach to nuclear crisis resolution using meta-game theory
(Rensselaer Polytechnic Institute, Troy, NY, 2014-08)Nuclear deterrence has been an important political goal for decades. It involves a strategy, cooperation and an understanding of the options and rationale of all parties involved. Simulations of these scenarios are very ... -

Reduced-order modeling of neutron transport by proper generalized decomposition
(Rensselaer Polytechnic Institute, Troy, NY, 2022-08)The numerical simulation of neutron transport within a nuclear reactor—for brevity, reactor physics—is the foundation on which analysts: design new reactors; license existing designs; prolong the licenses of operating ... -
Reducing image classification error and quantifying the contributions of components in a learning pipeline
(Rensselaer Polytechnic Institute, Troy, NY, 2018-08)In the second part of the Thesis, we try to understand the error contributions from different components of image classification pipelines. In the first work of this part, we are trying to quantify the quality of the ...
