Optimization-based multibody dynamics modeling method for team lifting simulation
(2019-12)
A novel optimization-based multibody dynamics modeling method is proposed for two-dimensional (2D) team lifting prediction. The box itself is modeled as a floating-base rigid body in Denavit-Hartenberg representation. The ...
Characterization of the impulsive jet produced from a dolphin's blowhole
(2020-12)
The health of bottlenose dolphins can be monitored by marine biologists through the analysis of their exhaled breath. Unique concepts to capture this breath in the wild include flying an Unmanned Aerial System (UAS) through ...
Explicit finite element analysis of web-roller interaction in web process machinery
(2013-05)
A web can be defined as thin material manufactured and processed in continuous flexible strip form. A web is usually supported, guided and propelled by rollers. In order to make it travel through the process machine line, ...
Measurements of viscoelastic properties by nanoindentation
(2007-05)
Scope and Method of Study: Nanoindentation technique was used to characterize the viscoelastic behavior of polymers. Methods were developed to measure linearly viscoelastic properties of polymers using nanoindentation. For ...
Augmented Invariant-EKF designs for simultaneous state and disturbance estimation
(2020-07)
In this thesis, we study Invariant-EKF designs for invariant systems with disturbances. We identify two sets of sufficient conditions that preserve the invariance of systems when additive dynamic disturbances are applied. ...
Galerkin CFD solvers for use in a multi-disciplinary suite for modeling advanced flight vehicles
(2013-05)
This work extends existing Galerkin CFD solvers for use in a multi-disciplinary suite. The suite is proposed as a means of modeling advanced flight vehicles, which exhibit strong coupling between aerodynamics, structural ...
Nonuniqueness and equivalence in online inverse reinforcement learning with applications to pilot performance modeling
(2023-05)
The focus of this thesis is behavior modeling for pilots of unmanned aerial vehicles.The pilot is assumed to make decisions that optimize an unknown cost functional, which is estimated from observed trajectories using a ...
Enhanced Vertical Ground Heat Exchanger Model for Whole Building Energy Simulation
(2019-07)
The U.S. Energy Information Agency estimates that buildings consume more than 40% of all energy used in the United States. This includes considering energy used for transportation and heavy industry. As a result, many ...
Effect of pregnancy-induced mass gain and footwear on postural stability
(2021-05)
Pregnancy induces tremendous changes in the body, which increases the risk of falling. Falls are rarely as costly as when they happen during pregnancy, leading to tremendous healthcare, emotional, and societal costs. More ...
