A brief history of topical invention in 20th century United States rhetorical studies
(Rensselaer Polytechnic Institute, Troy, NY, 2015-08)Although work on topical invention in the last century has neither a single coherent concept nor consistent terminology, it maintains a deep structure in which topics identify the sources for linkages that connect claims ... -
A contact model for geometrically accurate treatment of polytopes in simulation
(Rensselaer Polytechnic Institute, Troy, NY, 2014-12)I herein present a formulation of non-penetration constraints between pairs of bodies which accounts for all possible combinations of active contact. This is the first formulation that accurately models the body geometries ... -
A context-sensitive security type system for Java
(Rensselaer Polytechnic Institute, Troy, NY, 2015-05)This thesis presents the theoretical framework for A context-sensitive security type system for Java programs. The primary contribution is JSec, a two-stage protocol that prepares a program containing sensitive data to ... -
A discrete-continuous approximation model for optimal facility location in disaster response logistics
(Rensselaer Polytechnic Institute, Troy, NY, 2020-12)Disaster preparedness efforts regarding the location and prepositioning of relief supplies are becoming much more crucial than ever before. After major disasters and catastrophic events, local distribution is challenging ... -
A discrete-event simulation tool for resource constrained networks
(Rensselaer Polytechnic Institute, Troy, NY, 2015-12)Resource Constrained Networks (RCN) have become a hot topic in recent years, they includes Wireless Sensor Networks (WSN), Mobile Ad-Hoc Networks (MANET) and Delay-Tolerant Networks (DTN). Security is one of the major ... -
A framework for comparison of methods for solving complemetarity problems that arise in multibody dynamics
(Rensselaer Polytechnic Institute, Troy, NY, 2016-08)Among the simulation software packages in popular use today, there is no entirely satisfactory algorithm to compute the contact impacts with friction, and unbiased comparison and physical validation remain rare. Users with ... -
A framework for joint analysis of electrical impedance tomography and tomosynthesis data in breast cancer detection
(Rensselaer Polytechnic Institute, Troy, NY, 2008-05) -
A framework for representing and jointly reasoning over linguistic and non-linguistic knowledge
(Rensselaer Polytechnic Institute, Troy, NY, 2009-12) -
A genome-wide approach to aptamer discovery
(Rensselaer Polytechnic Institute, Troy, NY, 2020-05)Aptamers are short, single-stranded DNA or RNA oligonucleotides that bind with high specificity and affinity to a target molecule due to their unique, sequence-dependent secondary structure. They have found applications ... -
A high performance system for wireless transmission of power and data through solid metal enclosures
(Rensselaer Polytechnic Institute, Troy, NY, 2011-08) -
A highly parallel automated SFQ circuit design and margin optimization tool applied to a dual rail logic single flux quanta cell library
(Rensselaer Polytechnic Institute, Troy, NY, 2020-12)In this work circuits will be presented from an initial state where operating margins were optimized to the best of the ability of a more traditional, 1-Dimentional optimization algorithm. Issues with these designs will ... -
A hybrid approach to developing ontology-driven applications : a case study in describing radio spectrum usage policies
(Rensselaer Polytechnic Institute, Troy, NY, 2021-05)As such, applications need a simple and stable API that abstracts much of the structure, but keeps the strengths of OWL in reasoning or clarity. To meet this need, we utilize a hybrid approach to integrating an ontology ... -
A low-frequency investigation of acoustically coupled spaces using the finite-difference time-domain method
(Rensselaer Polytechnic Institute, Troy, NY, 2009-08) -
A method for (n,alpha) and (n,p) cross section measurements using a lead slowing-down spectrometer
(Rensselaer Polytechnic Institute, Troy, NY, 2012-08) -
A methodology to evaluate equity in resource accessibility
(Rensselaer Polytechnic Institute, Troy, NY, 2022-08)Inequalities present in society have been of increased interest in recent years, particularly in the United States. One source of inequality is unequal access to important resources, such as shopping. Recent developments ... -
A modified method for measurement in reverberation rooms
(Rensselaer Polytechnic Institute, Troy, NY, 2021-08)Unwanted noise within the built environment present a growing number of concerns for building users. Sound absorbers are frequently utilized to address these concerns. However, the characterization of their absorption ... -
A multi-material 3D printing system and model-based layer-to-layer control algorithm for ink-jet printing process
(Rensselaer Polytechnic Institute, Troy, NY, 2014-05)To address this issue, we propose a model-based feedback control law for ink-jet 3D printing that uses a height sensor for measuring profile height after each layer for determining the appropriate layer patterns for ... -
A multiscale study revealing the interplay between tumor growth and the three-dimensional extracellular matrix
(Rensselaer Polytechnic Institute, Troy, NY, 2019-12)To study biological processes of cancer progression is not an easy task – effort has been made to develop novel in vitro platforms that recapitulate physical features of the tumor microenvironment (TME) for cancer research. ... -
A network and agent basedmodel of political polarization
(Rensselaer Polytechnic Institute, Troy, NY, 2021-05)In this thesis we discuss the model from the paper “Polarization and Tipping Points” which the author of this thesis coauthored. We go into depth about the decisioning and reasoning behind multiple features of the model ... -
A network intrusion detection system (NIDS) based on information centrality to identify systemic cyber attacks in large systems
(Rensselaer Polytechnic Institute, Troy, NY, 2018-08)This thesis proposes a new approach to intrusion detection in networks. This approach is based on Information Centrality (IC) using which systemic attacks can perform the same level of intrusion detection using approximately ...
