Model-data fusion in digital twins of large scale dynamical systems
(2022-07)
Digital twins (DTs) are virtual entities that serve as the real-time digital counterparts of actual physical systems across their life-cycle. In a typical application of DTs, the physical system provides sensor measurements ...
Cooperative aerial manipulation with force control and attitude stabilization
(2018-12)
Ranging from autonomous flying cars, fixed wing and rotorcraft UAVs, there has been a tremendous interest in aerial robotics over the last decade. This thesis presents contributions to the state-of-art in cooperative payload ...
Coolant passage segmentation influence on regenerative-cooling effectiveness for small spacecraft thrusters
(2020-05)
The purpose of this thesis is to examine the effect of varying the number of cooling passages in a regeneratively-cooled rocket combustion chamber and nozzle analog for a small spacecraft thruster producing 22N (5lbf) ...
Environmental Applications for Photogrammetry with Unmanned Aerial Systems
(2019-05-01)
To explore current applications for the combination of Structure from Motion and Unmanned Aerial System technology in varying environments and with project specific goals, quantitative and qualitative datasets were gathered ...
Viscoelastic phenomena in roll-to-roll manufacturing - Two case studies of industrial relevance
(2020-12)
In the current manufacturing industry, Roll-to-Roll (R2R) manufacturing is in high demand because of its high productivity and low cost. Many materials used for R2R manufacturing are considered viscoelastic on some time ...
Automatic digital holographic analysis of near-field aerated liquid jets in crossflow
(2012-05)
Scope and Method of Study:
Modeling and control of transport behavior of moving webs through heat transfer processes
(2015-07)
Heat transfer processes are widely employed in Roll-to-Roll (R2R) process machines to heat/cool moving webs. The general goal is to efficiently transport webs over heating/cooling rollers and ovens while achieving the ...
Mechanics of Winding Laminate Webs and the Prediction of Machine Direction Curl
(2019-05-01)
Winding models that describe the residual stresses due to winding single layer webs at the end of roll-to-roll manufacturing machines began development over 50 years ago. These models have been used to reduce or avoid ...
Phase evolution, microstructure and wear behavior of al₀.₅cocrfeni₂ high entropy superalloy and al/al₀.₅cocrfeni₂ composites processed using spark plasma sintering
(2023-05)
High Entropy Superalloys (HESA), an extension of high entropy alloys, exhibit excellent high temperature properties with low density, making them a potential replacement for expensive and heavy superalloys and to be used ...
Modeling web handling systems and a method for determining feedback controller gains
(2020-07)
Modeling the longitudinal dynamics and control of web handling systems requires accurate models of the primitive elements involved, and an understanding of the processes used for speed and tension control. Primitive elements ...
