Comprehensive modeling of process-molten pool condition-property correlations for wire-feed laser additive manufacturing
Wire-feed laser additive manufacturing (WLAM) is gaining wide interest due to its high level of automation, high deposition rates, and good quality of printed parts. The complexity of modeling the directed energy deposition (DED) process, high characterization and printing cost, and the destructive …

In-situ prediction on sensor networks using distributed multiple linear regression models
Within sensor networks for environmental monitoring, a class of problems exists that requires in-situ control and modeling. In this thesis, we provide a solution to these problems, enabling model-driven computation where complex models are replaced by in-situ sensing and communication. These …
