PROSPECTS FOR THE USE OF COMPOSITE RESISTORS IN THE HARDWARE OF INFORMATION AND MEASUREMENT SYSTEMS
Background. Non-wire resistors are one of the most popular types of radio components. Their number in modern radio equipment reaches more than one third (40 %) of the total number of all resistors.

A blind contour‐aware quality model for sonar images
Since the penetration depth of visible light is limited in muddy and dark deep marine environment, sonar imaging, which is independent of natural light, has been attracting much attention in underwater detections.
