The Constant Multiplier FFT [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2021 In this paper, we present a new fast Fourier transform (FFT) hardware architecture called constant multiplier (CM) FFT. Whereas rotators in previous architectures must rotate among several different angles, the CM FFT exploits the use of constant ...

FFT-based Dynamic Token Mixer for Vision [PDF]
AAAI Conference on Artificial Intelligence, 2023 Multi-head-self-attention (MHSA)-equipped models have achieved notable performance in computer vision. Their computational complexity is proportional to quadratic numbers of pixels in input feature maps, resulting in slow processing, especially when ...

An FFT-based crystal plasticity phase-field model for micromechanical fatigue cracking based on the stored energy density [PDF]
International Journal of Fatigue, 2023 A novel FFT-based phase-field fracture framework for modelling fatigue crack initiation and propagation at the microscale is presented. A damage driving force is defined based on the stored energy and dislocation density, relating phase-field fracture ...

A simple extension of FFT-based methods to strain gradient loadings - Application to the homogenization of beams and plates with linear and non-linear behaviors [PDF]
Journal of Theoretical, Computational and Applied Mechanics, 2022 Because of their simplicity, efficiency and ability for parallelism, FFT-based methods are very attractive in the context of numerical periodic homogenization, especially when compared to standard FE codes used in the same context. They allow applying to

International Journal of Population Data Science, 2023 We examine the post age-16 educational pathways taken by the 44% of young people who do not gain “good” grades in English and Maths at age 16 years. We then assess the causal effects of attending General Further Education (GFE) colleges on education and
