Human-level natural language understanding : false progress and real challenges
(Rensselaer Polytechnic Institute, Troy, NY, 2013-12)The field of Natural Language Processing (NLP) focuses on the study of how utterances composed of human-level languages can be understood and generated. Typically, there are considered to be three intertwined levels of ... -
HVDC converters impedance modeling and system stability analysis
(Rensselaer Polytechnic Institute, Troy, NY, 2017-08)Harmonic linearization is used as the fundamental tool to model the sequence impedances of MMC and LCC as well as the frequency cross-coupling terms. Different from two level-VSC, the steady-state operation of MMC and LCC ... -
Hybrid materials design for SOFC interconnect applications
(Rensselaer Polytechnic Institute, Troy, NY, 2012-08) -
Hydrodynamic interactions in active and passive matter
(Rensselaer Polytechnic Institute, Troy, NY, 2017-05)Active matter is present at all biological length scales, from molecular apparatuses interior to cells, to swimming microscopic organisms, to birds, fish, and people. Its properties are varied and its applications diverse, ... -
Hydromagnetic driven waves in dusty interstellar clouds
(Rensselaer Polytechnic Institute, Troy, NY, 2011-05) -
Hydrophobicity, heat transfer, and momentum transfer at hard and soft aqueous interfaces
(Rensselaer Polytechnic Institute, Troy, NY, 2013-08)Interfaces also lead to anomalous behavior in heat and momentum transport. Interfaces disrupt local structure and create boundary resistances that manifest in temperature discontinuities and interfacial slip. We explore ... -
Identifying expertise : data exploration in Tetris
(Rensselaer Polytechnic Institute, Troy, NY, 2013-12)The identification of expertise in a complex task is trivial when all data is in after the fact. To achieve a better understanding of the nature of expertise my first goal, in this work, is to identify the behaviors most ... -
Identifying humpback whale flukes by sequence matching of trailing edge curvature
(Rensselaer Polytechnic Institute, Troy, NY, 2016-05)To our knowledge, this is the first method that can achieve this level of accuracy on humpback fluke identification without extensive manual effort at inference time. -
Identifying individual animals using ranking, verification, and connectivity
(Rensselaer Polytechnic Institute, Troy, NY, 2017-08)In this thesis we address the problem of identifying individual animals using images in the context of assisting an ecologist in performing a population census. We are motivated by events like the "Great Zebra Count" where ... -
Identity centered design : the liberating of the post-discretionary user
(Rensselaer Polytechnic Institute, Troy, NY, 2022-08)The intersection of critical creative practices and HCI was explored in an effort to create a design framework for developing material speculations in the form of communication tools that evoke critical reflection. In an ... -
Ignition delay measurements for n-dodecane/N2/air mixtures at high pressures
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)Ignition delay time measurements have been made in reflected shock experiments for n-dodecane at conditions relevant to diesel engines and those specifically found in the Engine Combustion Network Spray A experiments. The ... -
Image correlation across multiple image modalities and local spatial distortions
(Rensselaer Polytechnic Institute, Troy, NY, 2008-08)This thesis presents two techniques for correlating the pixels in two images of the same or similar subjects under various change conditions. The first technique is a new modality invariant keypoint descriptor that attempts ... -
Imaging moving targets in a multipath environment with multiple sensors
(Rensselaer Polytechnic Institute, Troy, NY, 2010-12) -
Impedance modeling and analysis of type-III wind turbines
(Rensselaer Polytechnic Institute, Troy, NY, 2016-08)Small-signal interaction between the power grid and converter-based generators is an issue that will become ever more present with the introduction of additional renewable generation year after year. A proven tool to ... -
Implementation of the transactor model : fault tolerant distributed computing using asynchronous local checkpointing
(Rensselaer Polytechnic Institute, Troy, NY, 2014-08)The Transactor model, an extension to the Actor Model, is a well-formulated way to model distributed concurrent systems while maintaining a global distributed state. This model provides semantics to track dependencies among ... -
Implementing and verifying the safety of the transactor model
(Rensselaer Polytechnic Institute, Troy, NY, 2008-05)The transactor model is an extension of the actor model designed to tolerate failures in distributed systems. Transactors can provide guarantees about consistency of a distributed system’s state in the face of message loss ... -
Improve speed performance of mass data storage systems
(Rensselaer Polytechnic Institute, Troy, NY, 2021-08)The objective of this thesis is to develop system-level design techniques that can improve the speed performance of mass data storage fabric built on low-cost magnetic recording hard disk drives (HDDs). This thesis first ... -
Improved fermion actions for analysis of technicolor theories
(Rensselaer Polytechnic Institute, Troy, NY, 2012-08) -
Improved first-order power analysis attacks on low entropy masking schemes
(Rensselaer Polytechnic Institute, Troy, NY, 2015-05)We validate the efficiency of this attack using side-channel measurements publicly available from the DPA Contest V4. We demonstrate that an attack modeling leakage using leakage sets can recover an encryption key with ... -
Improvement of high-speed coaxial rotor performance using redundant controls and camber morphing
(Rensselaer Polytechnic Institute, Troy, NY, 2018-12)CFD simulations were then undertaken for a rotor with reflex camber on the inboard sections of the blades. Two modified blade geometries were derived from the geometry of the X2 blade, one with a larger chord, greater ...
