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 ...
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, ...
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 ...
