Deep learning approach for chemistry and processing history prediction from materials microstructure

Autor: Amir Abbas Kazemzadeh Farizhandi, Omar Betancourt, Mahmood Mamivand

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-14 (2022)

Abstract Finding the chemical composition and processing history from a microstructure morphology for heterogeneous materials is desired in many applications. While the simulation methods based on physical concepts such as the phase-field method can

Autor: Daylon Black, Jim Browning, Ryan Harper, Winston Chern, Tayo Akinwande, Omar Betancourt, Stephen Longmuir, Theo Moodley, Donald Plumlee, Andy Yue, Patrick Moore, Tiffany Berntsen, Marcus Pearlman, Steven Saldivar, Tanya Lu

Publikováno v: 2018 IEEE International Conference on Plasma Science (ICOPS).

Magnetrons can be phase-locked using external systems. PIC simulations1 have shown that phase-locking is possible using modulated electron in jection to control the spoke formation. An experimental setup using Gated Field Emission Arrays (GFEAs) for

Statistical Evaluation of the Area Estimation of an Oil Spill Dispersion Model

Autor: Ann Wellens, Arturo Palacio Pe´rez, Alejandro Rodríguez Valdés, Fabian Omar Betancourt Quiroga

Publikováno v: Volume 2: Safety and Reliability; Pipeline Technology.

Computer models have proved to be useful tools to assess complex processes in environmental sciences. One type of application are oil spills, where models are used to provide insight into the processes interfering with the dispersion of the spill and

Mass Loss Evaluation in Oil Spill

Autor: Fabian Omar Betancourt Quiroga, Arturo Palacio Pe´rez, Alejandro Rodríguez Valdés

Publikováno v: 21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 2.

A revision of the models used to study the behavior of the mass loss processes associated with petroleum spills on water and to compare those models with experimental data (3,23). The processes of mass transfer studied in this work are evaporation, d

A Numerical Method for the Calculation of an Oil Spill Spreading

Autor: Arturo Palacio Pérez, Alejandro Rodríguez Valdés, Fabian Omar Betancourt Quiroga

Publikováno v: 21st International Conference on Offshore Mechanics and Arctic Engineering, Volume 2.

A revision to mathematical and numerical to use in order to determine the trajectory and growth of a spill of petroleum in water was done. A numerical model was compared with some field data (11,12) and mathematical models. This comparison allowed us
