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 ...
Daylight Saving Time will end on Sunday, Nov. 2, 2025, when clocks "fall back" one hour at 2 a.m. Despite past efforts like the Sunshine Protection Act, there is no permanent end to the time change ...
Abstract: Chaos correlation optical time domain reflectometry (OTDR), which has the advantage of no trade-off between resolution and dynamic range compared with conventional OTDR, can be used for ...
We covered the topic of taking over an old domain name from someone else and how that can sometimes be problematic in the Google SEO world. But here is a more recent comment from John Mueller of ...
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: Microwave detection of breast tumors has shown significant promise. This technology uses microwave transceivers such as vector network analyzers (VNA) or Ultrawideband (UWB) pulsed systems, ...
The Distributed Acoustic Sensing (DAS) system based on Phase-Sensitive Optical Time Domain Reflectometry (Φ-OTDR) uses narrow-linewidth lasers as high-coherence light sources, utilizing Rayleigh ...
A simple tweak to the usual setup is all that is needed to enhance a spectroscopy technique that uses terahertz wavelengths to probe samples, physicists at RIKEN University, Wakō, Japan, have ...
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 ...
