In video games using procedural world generation, the map seed is a (relatively) short number or text string which is used to procedurally create the game world ("map"). "). This means that while the seed-unique generated map may be many megabytes in size (often generated incrementally and virtually unlimited in potential size), it is possible to reset to the unmodified map, or the unmodified ...
Acoustic location is a method of determining the position of an object or sound source by using sound waves. Location can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the earth).
A database shard, or simply a shard, is a horizontal partition of data in a database or search engine. Each shard may be held on a separate database server instance, to spread load. Some data within a database remains present in all shards, [a] but some appear only in a single shard. Each shard (or server) acts as the single source for this ...
Animal echolocation, non-human animals emitting sound waves and listening to the echo in order to locate objects or navigate. Human echolocation , the use of sound by people to navigate. Sonar ( so und n avigation a nd r anging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.
Project Echo was the first passive communications satellite experiment. Each of the two American spacecraft, launched in 1960 and 1964, were metalized balloon satellites acting as passive reflectors of microwave signals. Communication signals were transmitted from one location on Earth and bounced off the surface of the satellite to another ...
Another form of jamming occurs when an echolocating animal produces many sounds in succession and assigns an echo to the wrong emission. To avoid this type of jamming, bats typically wait enough time for echoes to return from all possible targets before making the next sound. This can be seen clearly when a bat attacks an insect.

Echo Lake has played an important role in Shoreline's history. During the 1800s, logging was a significant industry in the region. In the early 1900s, Mowatt's Sawmill operated at the north end of Echo Lake. [1] From 1916 to 1996, the lake had a bathing beach that cost a nickel for admission.
