Fast parallel multidimensional FFT using advanced MPI [PDF]
J. Parallel Distributed Comput., 2018 We present a new method for performing global redistributions of multidimensional arrays essential to parallel fast Fourier (or similar) transforms. Traditional methods use standard all-to-all collective communication of contiguous memory buffers, thus ...

Design and Implementation of Three-phase Precision Program-controlled Standard Source
Zhejiang dianli, 2022 The traditional program-controlled standard source cannot meet the requirements of the OIML R46 standard on small current and harmonic output accuracy. For the sake of improving the steady-state output accuracy and dynamic response speed of the standard ...

A 64-point Fourier transform chip for high-speed wireless LAN application using OFDM
, 2004 In this article, we present a novel fixed-point 16-bit word-width 64-point FFT/IFFT processor developed primarily for the application in the OFDM based IEEE 802.11a Wireless LAN (WLAN) baseband processor.

, 2007 The split-radix FFT computes a size-n complex DFT, when n is a large power of 2, using just arithmetic operations on real numbers. This operation count was first announced in 1968, stood unchallenged for more than thirty years, and was widely believed to be best possible. Recently James Van Buskirk posted software demonstrating that the split-radix FFT

A machine sound monitoring for predictive maintenance focusing on very low frequency band
SICE Journal of Control, Measurement, and System Integration, 2021 The monitoring of machines is one of key issues in the Industry 4.0 era. Particularly, the monitoring realized by non-contact sensors is drawing attention since it is easy to install and to avoid any problems caused by sensors accidentally dropping down ...

TBK1‐Associated Primary Lateral Sclerosis Followed by Right Temporal Variant Frontotemporal Dementia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT We report a 58‐year‐old woman with a novel splice‐site variant in the TANK‐binding kinase 1 (TBK1:c.993–2A>C p.Ala332TyrfsTer39) who sequentially developed primary lateral sclerosis (PLS) followed by right temporal variant frontotemporal dementia (rtvFTD). Neuroimaging demonstrated right anterior temporal atrophy before cognitive symptoms, and
