AI-driven process monitoring enhances the qualification of additively manufactured stainless-steel parts. By analysing high-frequency welding current and voltage signals in both the time and frequency ...

Abstract: In this article, we propose a general discontinuous Galerkin time-domain (DGTD) method for analyzing electromagnetic scattering from full-tensor anisotropic materials, both lossy and ...

A time domain reflectometer (TDR) measures reflections along a cable. It is similar in principle to radar. To measure those reflections, the TDR transmits an incident signal into the cable and watches ...

Abstract: We present a comprehensive tutorial on the finite-difference time-domain (FDTD) modeling of space, time, and space-time-varying media, building upon our previous review by offering a ...

In this look at transmission line theory, we will assume an RG-58 type of coaxial cable which has a characteristic impedance of 50 Ω. Where we let C stand for the capacitance per unit length, 30 pF ...

Generating time series data is important for many applications, including data augmentation, synthetic datasets, and scenarios. However, when there is more than one, this process becomes too complex ...

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 ...

A new year means a new start, and for some pieces of media, it means entering the public domain. In 2024, one of the most famous additions to the public domain was the first iteration of Mickey Mouse, ...

Time Machine, the built-in backup tool in macOS, provides a straightforward and reliable way to protect your valuable data. Whether you’re safeguarding critical work files, cherished family photos, or ...

This series, Space in Focus, explores key space trends, challenges, and policy issues that will confront the next administration as well as offers recommendations for how to navigate them. The rapid ...
