Mauro Zammarano, Carola Esposito Corcione, Francesca Ferrari, Raffaella Striani, Laura J. Dubrulle, Paolo Visconti, Antonio Greco
In our previous study, an innovative method for sterilization, inertization, and valorization of organic fraction of the municipal solid waste (OFMSW), to be recycled in the production of composite panels, had been developed. In this follow-up work, the

Simulations of Flow Over an Axisymmetric Hill

February 26, 2021
Author(s)
Rikhi Bose, DongHun Yeo
In this report, high-Reynolds number turbulent flow around an axisymmetric hill is studied using large eddy and unsteady Reynolds averaged Navier-Stokes simulations and the results are extensively validated against experiment. The boundary-layer thickness

Towards Deep Transfer Learning in Industrial Internet of Things

February 26, 2021
Author(s)
Xing Liu, Wei Yu, Fan Liang, David Griffith, Nada T. Golmie
In this paper, we propose a general framework to adopt transfer learning in IIoT systems. Transfer learning is a machine learning technique that fully uses the knowledge from pre- trained models to reduce the computing requirements for the training process
