SONAR (sound navigation and ranging) systems have many similarities to RADAR and electro-optical systems. Again, detection is based on the propagation of waves between the target and detector. There... More > are active sonar systems, where the wave propagates from the transmitter to the target and back to the receiver, analogous to pulse-echo radar. There are also passive sonar systems, where the target is the source of the energy which propagates to the receiver, analogous to passive infrared detection. Therefore, a great deal of what has been discussed about these systems will also apply to sonar.

More > data. Michael Mandberg wrote software that parses the entirety of the English-language Wikipedia database and programmatically lays out nearly 7500 volumes, complete with covers, and then uploads them to for print-on-demand. Print Wikipedia draws attention to the sheer size of the encyclopedia's content and the impossibility of rendering Wikipedia as a material object in fixed form: Once a volume is printed it is already out of date. It is also a work of found poetry built on what is likely the largest appropriation ever made. As we become increasingly more dependent on information and source material on the Internet today, Mandiberg explores the accessibility of its vastness.< Less
