Abstract: Distributed acoustic sensing systems based on phase-sensitive optical time-domain reflectometry have been used in several applications, especially in oil and gas fields and seismic ...

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest ...

In the north of the Wild Island region, you'll find the Waste Processing Station. As you approach, you'll hear a distress call coming from Jumper. Enter the small one-story building across from the ...

Abstract: Utilizing periodic phase modulation (PPM) can shift the echo spectrum, affecting matched filtering (MF) processing, leading to time delay shift or amplitude attenuation. The prior works on ...
