Penn Engineers have developed a new way to use AI to solve inverse partial differential equations (PDEs), a particularly challenging class of mathematical problems with broad implications for ...

Abstract: Spectral Photon Counting Computed Tomography (SPCCT) is a novel imaging technique that uses photon counting detectors to acquire images across multiple X-ray energy windows. This energy ...

Customers can accelerate the reduction of their legacy tech debt and shift valuable resources toward innovation. We are introducing new agentic capabilities in AWS Transform to accelerate organization ...

Here’s a draft of my next column for the Notices of the American Mathematical Society. It’s about the inverse cube force law in classical mechanics. Newton’s Principia is famous for his investigations ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

A few months ago, I completed a FOC project and wrote an article to share the learning process. However, due to the laziness, the plan paused at that point. Now I will start this series again with ...

A demonstration of the effects of downsampling (with and without anti-aliasing) on an audio signal, using the built-in handel sample in MATLAB. This project visualizes both time-domain and ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...

The inverse Fourier transform (inverse FFT or iFFT) reverses the operation of the Fourier transform and derives a time-domain representation from a frequency-domain dataset. Figure 1. The inverse ...
