Abstract: An accurate frequency estimator of complex sinusoid in additive white noise is proposed. It is based on interpolation of Fast Fourier Transform (FFT) and Discrete-Time Fourier Transform ...

More than 20% of the workload on the world's 500 fastest supercomputers is spent simulating how atoms and molecules move—with applications ranging from material design to identifying drug interactions ...

Abstract: Multistatic millimeter-wave (MMW) imaging systems offer advantages in imaging objects with high contour complexity. Traditional reconstruction algorithms, such as the Back Projection (BP) ...

PFFFT does 1D Fast Fourier Transforms, of single precision real and complex vectors. It tries do it fast, it tries to be correct, and it tries to be small. Computations do take advantage of ...

An efficient FFT-based model for medical image segmentation. The algorithm is elaborated on our paper [FFTMed: Leveraging Fast-Fourier Transform for a Lightweight and Adversarial-Resilient Medical ...

Researchers from the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Northeastern University, Google ...

Conventional computers process and store information using separate components, known as a processor and memory unit. Because ...

The big-idea explorers at Aperture dive into the alarming reality of modern brain rot to reveal why this cultural phenomenon is far worse than you think. Coffee linked to significant new side effect, ...

For most of the industry’s history, the lever for semiconductor performance gains was process-node scaling. That is no longer the whole story. As one recent industry analysis put it, advanced ...

What about ChatGPT and related large AI Systems? How will they impact us all? As a longtime researcher in AI, I'm excited about the ways in which these new AI systems can improve our healthcare, ...
