Modeling and Simulation of Nonlinear Dynamics Using Physics-Informed Deep Neural Networks

Seid Hosein Pourtakdoust; A. H. Khodabakhsh

Volume 6, Issue 4 , February 2023, , Pages 25-36

https://doi.org/10.22034/jtae.2023.6.4.3

Abstract
  Development of Physics-Informed Neural Networks (PINNs) as nonlinear dynamics surrogates is investigated. PINNs are unsupervised neural networks in which the input-output relationship is established via a specific dynamic relationship (differential equation). In this regard, the derivatives are determined ...  Read More

Optimization of an Unmanned Aerial Vehicle Using Fuzzy Logic and Multidisciplinary Design Optimization

Mohammad reza Setayandeh; Alireza Babaei

Volume 5, Issue 2 , August 2021, , Pages 29-41

https://doi.org/10.22034/jtae.2021.129738

Abstract
  This research tries to propose a method to solve problems related to constrained multi-objective optimizations (implementation, computation time, and simplicity). This method, based on fuzzy logic, converts constrained multi-objective optimization problem into unconstrained single-objective optimization ...  Read More
