Acoustic Tags transmit a signal made up of acoustic pulses or "pings" that sends location information about the tagged organism to the hydrophone receiver. By tying the received acoustic signature to the known type of programmed signal code, the specific tagged individual is identified.
The 9000 was one of the first analog video recorders utilized for electronic film production using analog high-resolution wideband video standards (such as the 655/48 standard mentioned previously), predating DI (digital intermediate) film production systems in use today. The 9000-W-M was, for all intents and purposes, a custom pre-HDTV video ...
Dr. Kenichi Sawazaki developed a prototype helical scan recorder in 1954. [29] Helical scan machines were demonstrated by Toshiba in 1959 and since they recorded one field of video per track, they were the first to allow video to be paused and played back at speeds other than real time. Helical scan type B and type C videotape began to be used ...
Amateur television (ATV) is the transmission of broadcast quality video and audio over the wide range of frequencies of radio waves allocated for radio amateur (Ham) use. [1] ATV is used for non-commercial experimentation, pleasure, and public service events.
Marine shrimp farming is an aquaculture business for the cultivation of marine shrimp or prawns [Note 1] for human consumption. Although traditional shrimp farming has been carried out in Asia for centuries, large-scale commercial shrimp farming began in the 1970s, and production grew steeply, particularly to match the market demands of the United States, Japan and Western Europe.
For a fixed bandwidth, interlace provides a video signal with twice the display refresh rate for a given line count (versus progressive scan video at a similar frame rate—for instance 1080i at 60 half-frames per second, vs. 1080p at 30 full frames per second). The higher refresh rate improves the appearance of an object in motion, because it ...
In Indonesia, snakehead fish, called ikan gabus, are served as the main parts of traditional dishes such as the Betawi people's pucung gabus, and considered to be a delicacy due to their rarity in the wild and in aquaculture, as they are harder to raise than other popular freshwater fish such as catfish and carp.
The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed. More generally, "slit-scan photography" refers to cameras that use a slit, which is particularly used in scanning cameras in panoramic ...
