Reduced-order modeling of soft robots. [PDF]

open access: yesPLoS ONE, 2018
We present a general strategy for the modeling and simulation-based control of soft robots. Although the presented methodology is completely general, we restrict ourselves to the analysis of a model robot made of hyperelastic materials and actuated by ...

Reduced order modeling and model order reduction for continuum manipulators: an overview [PDF]

open access: yesFrontiers in Robotics and AI, 2023
Soft robot’s natural dynamics calls for the development of tailored modeling techniques for control. However, the high-dimensional configuration space of the geometrically exact modeling approaches for soft robots, i.e., Cosserat rod and Finite Element ...

Reduced order modeling with shallow recurrent decoder networks [PDF]

open access: yesNature Communications
Reduced order modeling is of paramount importance for efficiently inferring high-dimensional spatio-temporal fields in parametric contexts. However, conventional dimensionality reduction techniques are typically limited to known and constant parameters ...

Lagrangian Reduced Order Modeling Using Finite Time Lyapunov Exponents

open access: yesFluids, 2020
There are two main strategies for improving the projection-based reduced order model (ROM) accuracy—(i) improving the ROM, that is, adding new terms to the standard ROM; and (ii) improving the ROM basis, that is, constructing ROM bases that yield more ...

Reduced order modeling and analysis of the human complement system. [PDF]

open access: yesPLoS ONE, 2017
Complement is an important pathway in innate immunity, inflammation, and many disease processes. However, despite its importance, there are few validated mathematical models of complement activation.

Geometry Reduced Order Modeling (GROM) with application to modeling of glymphatic function

open access: yesBrain Research Bulletin
Computational modeling of the brain has become a key part of understanding how the brain clears metabolic waste, but patient-specific modeling on a significant scale is still out of reach with current methods. We introduce a novel approach for leveraging

Progressive transfer learning for advancing machine learning-based reduced-order modeling [PDF]

open access: yesScientific Reports
To maximize knowledge transfer and improve the data requirement for data-driven machine learning (ML) modeling, a progressive transfer learning for reduced-order modeling (p-ROM) framework is proposed.

REDUCED-ORDER MODELLING OF PARAMETERIZED TRANSIENT FLOWS IN CLOSED-LOOP SYSTEMS [PDF]

open access: yesEPJ Web of Conferences, 2021
In this paper, two Galerkin projection based reduced basis approaches are investigated for the reduced-order modeling of parameterized incompressible Navier-Stokes equations for laminar transient flows. The first approach solves only the reduced momentum
