Failure mechanisms of metallic glasses via atomic scale simulations
(Rensselaer Polytechnic Institute, Troy, NY, 2014-12)Metallic glasses (MGs) are an emerging class of structural materials that can achieve a combination of striking mechanical properties, such as high strength, large elastic limit, high fracture toughness, plastic-like ... -
Fatigue and fracture in polymer networks and their composites
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)Fatigue is encountered in wide spectrum applications varying from biomaterials to energy storage devices. As we explore novel materials to meet stringent performance demands of new applications, strategies to tackle fatigue ... -
Feasibility of using dynamically oscillating surfaces to control Tollmien-Schlichting waves
(Rensselaer Polytechnic Institute, Troy, NY, 2016-08)This work characterizes and controls Tollmien-Schlichting (T-S) waves by means of Piezoelectrically-Driven Oscillating Surface (PDOS) actuators, using Particle Image Velocimetry (PIV). A parametric study of PDOS actuator ... -
Fetilda : a framework for fin-tuned embeddings of long financial text documents
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)Increasingly, unstructured data are being utilized in different domains. In particular, textual data, in recent years, is becoming more important. When it comes to financial applications, unstructured data, such as text ... -
Field cuts : Encounter 6
(Rensselaer Polytechnic Institute, Troy, NY, 2016-05)This thesis provides documentation of the creation and development of Field Cuts: Encounter 6, an electrically/electronically mediated movement performance for three dancers that explores the ability of performers to ... -
Finding the 'I' in team: development of a snapshot individual performance metric
(Rensselaer Polytechnic Institute, Troy, NY, 2017-05)Though both individual and team performance are widely studied, evaluating individual performance within the context of the team usually relies on relative measures of performance. However, in order to apply much of the ... -
First principles investigations of electronic structure and transport properties of graphitic structures and single molecular junctions
(Rensselaer Polytechnic Institute, Troy, NY, 2014-12)The first two projects pertain to nitrogen doping in graphene nanoribbons (GNRs). We study nitrogen doping in two different schema: concentration-based (Nx$-doped) and structural based (N2AA-doped). -
First principles study of intein reaction mechanisms
(Rensselaer Polytechnic Institute, Troy, NY, 2008-05) -
First-principles studies of defect dynamics in crystalline solids
(Rensselaer Polytechnic Institute, Troy, NY, 2020-05)To this end, two classes of defect dynamics are considered. The first is passive dynamics, in which the evolution of defects is probabilistic, and its rate is dictated only by the environmental conditions in which the ... -
Flow control actuator in microchannel
(Rensselaer Polytechnic Institute, Troy, NY, 2010-05) -
Flow control in a transonic diffuser through mass and vorticity injection to mitigate massive separation
(Rensselaer Polytechnic Institute, Troy, NY, 2017-05)An experimental flow control investigation was conducted in two test articles: an S-duct and a diffuser, both at high-subsonic conditions. -
Flow physics and sensitivity study of synthetic jets-based flow control of 3-D configurations
(Rensselaer Polytechnic Institute, Troy, NY, 2018-05)Bridging the gap between sub-scale, fundamental studies of synthetic jet actuators on aerodynamic models and full-scale applications on actual vehicles requires a thorough understanding of how the synthetic jets interact ... -
Forecasting collective behavior using social media
(Rensselaer Polytechnic Institute, Troy, NY, 2018-12)This thesis constructs hypotheses and measurements based on theoretical explanations of collective behaviors using a modeling framework informed by Emergent Norm Theory. Developed long before the Internet, the theory ... -
Formal verification of decentralized coordination in autonomous multi-agent aerospace systems
(Rensselaer Polytechnic Institute, Troy, NY, 2022-05)As autonomous vehicular technologies such as self-driving cars and uncrewed aircraft systems (UAS) evolve to become more accessible and cost-efficient, autonomous multi-agentsystems, that comprise of such entities, will ... -
Formation and shearing of drops with applications in biophysics and bioprocessing
(Rensselaer Polytechnic Institute, Troy, NY, 2017-12)Drops are self-contained systems which do not need solid walls as surface tension provides containment. Solid walls can have associated issues such as sorption, chemical and electrostatic effects which can complicate the ... -
Four essays analyzing the impacts of policy and system changes on power sector emissions
(Rensselaer Polytechnic Institute, Troy, NY, 2015-05)The Regional Greenhouse Gas Initiative (RGGI) is a regionally based carbon dioxide (CO2) cap and trade policy. A potential weakness of regional emissions trading policies is that they can incur "leakage" if emission ... -
