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 ...

Figure 1. Illustration of the TDR in situ measurement. Note that the compaction of the soil samples with high water contents is unrealistic to achieve the predefined dry densities mentioned above. To ...

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 ...

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 ...

Objective: This study aims to develop a multimodal deep learning-based stress detection method (MMFD-SD) using intermittently collected physiological signals from wearable devices, including ...

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 ...

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 ...
