Integrated Free Energy Model (IFEM) for microemulsions

Journal of Colloid and Interface Science, 2016
The Integrated Free Energy Model (IFEM) is a platform used to predict the solubilization of nonpolar oils in nonionic alkyl-polyethylene oxide (C(X)EO(Y)) micelles starting from a free energy balance of costs and gains when surfactants from empty micelles and oil from a continuous oil phase assemble to form an oil-swollen micelle.

iFEM benchmark problems for solid elements

Smart Materials and Structures, 2019
Structural health monitoring (SHM) is a growing field of research, as it has the potential to simultaneously improve the reliability of structures and reduce their maintenance cost. SHM requires accurate stress and strain information, preferably for the entire structure.

Geometrically Nonlinear Deformation Reconstruction Based on iQS4 Elements Using a Linearized Iterative iFEM Algorithm

Acta Mechanica Solida Sinica, 2022
Structural shape monitoring plays a vital role in the structural health monitoring systems. The inverse finite element method (iFEM) has been demonstrated to be a practical method of deformation reconstruction owing to its unique advantages. Current iFEM formulations have been applied to small deformation of structures based on the small-displacement ...

IFEMS: a new approach for monitoring wildfire evolution with NOAA-AVHRR imagery

International Journal of Remote Sensing, 2001
A new approach for monitoring wildfire evolution was developed. It was achieved by integrating both the burned area mapping system and the fire detection system. Multi-spectral multi-temporal images of the National Oceanic and Atmospheric Administration Advanced Very High Resolution Radiometer (NOAA-AVHRR) were employed. The new system has an excellent

iFEM Implementation on a Rotating Shaft for Imbalance Identification

Proceedings of the 15th International Workshop on Structural Health Monitoring
Structural Health Monitoring (SHM) is crucial for ensuring the safety and reliability of rotating machinery. In rotating shafts, structural damage can affect force distribution and alter dynamic behavior. This study conducts a preliminary numerical investigation into the application of the inverse Finite Element Method (iFEM) for rotor monitoring ...

Improving iFEM-based wing deformation reconstruction accuracy with IMU-assisted calibration

Measurement Science and Technology
Abstract To address the degradation in reconstruction accuracy of inverse finite element methods (iFEMs) for wing deformation—caused by discrepancies between the simulation model and the physical system, including model simplifications, mismatched loading conditions, and strain sensor installation errors—as well as the high cost and ...

On a staggered iFEM approach to account for friction in compression testing of soft materials

Journal of the Mechanical Behavior of Biomedical Materials, 2013
An inverse finite element method (iFEM) to estimate material parameters from compression tests of soft materials is presented, where alginate hydrogel was used as a phantom material. The method applies if the boundary conditions at the loaded surfaces are not ideal, i.e.

Inchrononym Fractal Emergence Model (IFEM)

The Inchrononym Fractal Emergence Model (IFEM) Version 4 presents a theoretical transition from geometric fractality to informational emergence as the foundational substrate of physical phenomena. This model reinterprets fractal structures not as mere geometric configurations but as compressed informational programs whose dynamics unfold through ...
