Uncanny tourism : rhetorical placemaking in Sleepy Hollow, NY
(Rensselaer Polytechnic Institute, Troy, NY, 2021-05)In the village of Sleepy Hollow, NY, local author Washington Irving’s 1819 short story “The Legend of Sleepy Hollow” is the basis for a Halloween season tourism industry. Combining a rhetorical analysis enriched by ... -
Understanding and improvement of eVTOL UAV performance through high-fidelity analysis of interactional aerodynamics
(Rensselaer Polytechnic Institute, Troy, NY, 2019-08)The reduced cost and complexity of these designs has lead to research endeavors attempting to model the flight dynamics of the vehicle with low-order, computationally efficient models. The lowest of these models simply ... -
Understanding cell wall lytic enzyme behavior in microbial consortium and bacterial growth supporting environments
(Rensselaer Polytechnic Institute, Troy, NY, 2020-08)However, there was a reduction in the antimicrobial efficacy of both Lst and PlyPH in the actively growing consortium compared to non-growing conditions. Lst and PlyPH were found to be inhibited by proteases secreted during ... -
Understanding prominence on massive and anonymous social news sites
(Rensselaer Polytechnic Institute, Troy, NY, 2013-05)Many algorithms have been proposed to measure prominence of individuals in social networks. However, these algorithms are highly dependent on the underlying mechanisms for judging how individuals gain prominence in a given ... -
Understanding the mechanism of polyphenolic inhibition on human vascular NADPH oxidase
(Rensselaer Polytechnic Institute, Troy, NY, 2007-12) -
Understanding the structure and deformation of titanium-containing silicate glasses from their elastic responses to external stimuli
(Rensselaer Polytechnic Institute, Troy, NY, 2016-08)For Na2O-TiO2-SiO2 glasses, the response to mechanical damage and plastic deformation has been examined through Vickers indentation experiments at loads from 10 mN to 49 N. Fracture toughness was measured through the ... -
Universal control techniques for fault-tolerant multi-phase permanent magnet motor drives
(Rensselaer Polytechnic Institute, Troy, NY, 2014-08)In this work, universal approaches are developed for high performance of multi-phase permanent magnet motor drives under fault conditions. Ideally high performance operation under fault conditions is considered as maximum ... -
Unsupervised graph-based relation extraction and validation for knowledge base population
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)To populate KBs, researchers have made significant progress in relation extraction from unstructured text corpora. However, it remains very challenging since a relation can be expressed in numerous ways through a sophisticated ... -
Unsupervised learning : evaluation, distributed setting, and privacy
(Rensselaer Polytechnic Institute, Troy, NY, 2018-05)Chapter 1 is an overview of topic modeling as a set of unsupervised learning tasks. We present the Latent Dirichlet Allocation (LDA) model, and show how k-means as well as non- negative matrix factorization (NMF) can also ... -
Unweaving the tangled web : using BHB stars to trace tidal streams in the Galactic halo
(Rensselaer Polytechnic Institute, Troy, NY, 2019-08)Mapping and analyzing substructure in the halo of the Milky Way is our primary way of investigating the morphology and composition of the Milky Way's dark matter halo, the Galaxy's accretion history, and ultimately, models ... -
Updates : technologies of media change
(Rensselaer Polytechnic Institute, Troy, NY, 2015-12)Whether as status notifications in news feeds or interactive prompts in online video services, updates punctuate the background routines of media by bringing a variety of changes to the attention of users. In this dissertation ... -
Upwind methods for second-order wave equations on overlapping grids
(Rensselaer Polytechnic Institute, Troy, NY, 2018-08)A normal mode analysis from the theory of Gustafsson, Kreiss, and Sundstrm (GKS) shows that these schemes are robustly stable against numerical instabilities that are known to arise from overlapping grid interpolation. A ... -
Urban ecosystem justice : the field guide to a socio-ecological systems science of cities for the people
(Rensselaer Polytechnic Institute, Troy, NY, 2018-05)This dissertation analyzes efforts to understand and build urban ecosystem health and justice, extending scholarly literatures on urban ecology, political ecology and environmental justice. Through examination of cases ... -
Urban expansion approached through materialism

User-centric design and validation of a haptic interface for endotracheal intubation
(Rensselaer Polytechnic Institute, Troy, NY, 2020-05)We propose a user-centric approach to developing high-fidelity haptic environments and demonstrate this process with training endotracheal intubation (ETI). We began by understanding the medical procedure and simulator ... -
Using diffusion equation model to analyze advanced sound energy decay in reverberation chamber
(Rensselaer Polytechnic Institute, Troy, NY, 2022-08)In the room acoustics measurement process, a non-diffused sound field is neglected in conventional chamber-based studies of absorbing materials, which reduces accuracy and can even produce inconsistent results. An additional ... -
