security in leakage positions and source node position, efficiency in cost, and reliability transmission. By contrast, subsea cables of offshore wind plans are High voltage current. Any damage of these cables can lead to a catastrophic disaster for ecological environment of living creatures. Moreover...
finding applications in system monitoring, anomaly/fault detection, control, and various other areas. With technological advancements, today such systems might include hundreds or thousands of sensors that generate large amounts of multivariate data streams. This inevitably results in increased ...
of resolving wavelengths as close as 10−3nanometre, while modern laser techniques can resolve optical wavelengths separated by less than 10−10nanometre. The frequency with which the electromagnetic wave oscillates is also used to characterize the radiation. The product of the frequency (ν) and...
threatening food production and security. Therefore, tackling its effects has never been so imperative to attain sustainable food access and nutrition worldwide. In the case of viticulture, besides jeopardizing grape production, climate change has severe impact in quality, which has becoming more challe...
which used an argon laser. A few years later, Hartog et al. used a semiconductor laser as a light generator to inject the sensing fiber-line, and consequently, developed the first sensor based on the principles of Raman scattering49. Subsequently, the Raman distributed optical fiber sensors hav...
Optical fibre networks are advancing rapidly to meet growing traffic demands. Security issues, including attack management, have become increasingly important for optical communication networks because of the vulnerabilities associated with tapping light

In 1997, The Air Force of the United States of America has approved an anti-ballistic Airborne Laser system. The 747-based system was built by TRW and Lockheed Martin. In 1998, Steven Chu won Nobel Prize for developing the method of cooling and trapping atoms with laser light. ...
Abstract Thermal cameras are passive sensors that capture the infrared radiation emitted by all objects with a temperature above absolute zero. This type of camera was originally developed as a surveillance and night vision tool for the military, but recently the price has dropped, significantly openi...
