Customization of the angular spectrum method for calculating the acoustic piston field transmitted through a solid plate using MATLAB

open access: yesMethodsX, 2023
The angular spectrum (AS) model is customized to calculate the spatial acoustic pressure field generated by a piston source and transmitted through a steel plate immersed in water, for normal beam incidence.

PySimulator – A Simulation and Analysis Environment in Python with Plugin Infrastructure

open access: yes, 2012
A new simulation and analysis environment in Python is introduced. The environment provides a graphical user interface for simulating different model types (currently Functional Mockup Units and Modelica Models), plotting result variables and applying ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...

Fourier-based contour descriptors to relax positional standardization of the otolith images in AFORO queries

open access: yesScientia Marina, 2020
The otolith digital catalogue AFORO allows unknown otoliths to be classified automatically by using a comparison with its classified records. To do this, the otolith’s contour, which is extracted from an image, is used.

An Application to Transient Current Signal based Induction Motor Fault Diagnosis of Fourier-Bessel Expansion and Simplified Fuzzy ARTMAP [PDF]

open access: yes, 2013
The start-up transient signals have been widely used for fault diagnosis of induction motor because they can reveal early defects in the development process, which are not easily detected with the signals in the steady state operation. However, transient

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

open access: yesAdvanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Mix-Spectrum for Generalization in Visual Reinforcement Learning

open access: yesIEEE Access
Visual Reinforcement Learning (RL) trains agents on policies using images showing the potential for real-world applications. However, the limited diversity in the training environment often results in overfitting with agents underperforming in unseen ...

Fast generalized Fourier transforms

open access: yesTheoretical Computer Science, 1989
Computational complexity of the fast generalized Fourier transforms is discussed on the basis of the Wedderburn's structure theorem. In the sequel, the upper bound of the linear complexity is confidently estimated.
