Data Assimilation in Chaotic Systems Using Deep Reinforcement Learning
Mohamad Abed El Rahman Hammoud, Naila Raboudi, Edriss S. Titi +2
Data assimilation (DA) plays a pivotal role in diverse applications, ranging from climate predictions and weather forecasts to trajectory planning for autonomous vehicles. A prime…
Oil Spill Risk Analysis For The NEOM Shoreline
HVR Mittal, Mohamad Abed El Rahman Hammoud, Ana K. Carrasco +2
A risk analysis is conducted considering several release sources located around the NEOM shoreline. The sources are selected close to the coast and in neighboring regions of high m…
Finite element discretizations for variable-order fractional diffusion problems
Wenyu Lei, George Turkiyyah, Omar Knio
We present a finite element scheme for fractional diffusion problems with varying diffusivity and fractional order. We consider a symmetric integral form of these nonlocal equation…
Continuous and Discrete Data Assimilation with Noisy Observations for the Rayleigh-Benard Convection: A Computational Study
Mohamad Abed El Rahman Hammoud, Olivier LeMaitre, Edriss S. Titi +2
Obtaining accurate high-resolution representations of model outputs is essential to describe the system dynamics. In general, however, only spatially- and temporally-coarse observa…
Enhanced Simulation of the Indian Summer Monsoon Rainfall Using Regional Climate Modeling and Continuous Data Assimilation
Srinivas Desamsetti, Hari Prasad Dasari, Sabique Langodan +6
This study assesses a Continuous Data Assimilation (CDA) dynamical-downscaling algorithm for enhancing the simulation of the Indian summer monsoon (ISM) system. CDA is a mathematic…
H2Opus: A distributed-memory multi-GPU software package for non-local operators
Stefano Zampini, Wajih Boukaram, George Turkiyyah +2
Hierarchical -matrices are asymptotically optimal representations for the discretizations of non-local operators such as those arising in integral equations or from…
