The counterpart of anomaly detection in intrusion detection is misuse detection. An MRI artifact is a visual artifact, that is, an anomaly during visual representation. Barker's equation relates the time of flight to the true anomaly of a parabolic trajectory. He assumes that the temporal anomaly was caused by Hiro. Three broad categories of anomaly detection techniques exist. The errors were due to what was described as an "electromagnetic anomaly". Fluorine is something of an anomaly in this circumstance. Maps produced have included free-air gravity anomaly, Bouguer gravity anomaly, and crustal thickness. Deposits are confined to the Kursk Magnetic Anomaly area. Traveling there they find a special space station ("space anomaly") where many strange aliens reside. Polyclonal hypergammaglobulinemia is also a fairly common immunologic anomaly seen in sarcoidosis. Bangui is located at the center of a large anomaly in the Earth's magnetic field. As a result, there is sustained interest in the nature of this so-called "Pioneer anomaly". Upon his return, he was part of a team that investigated a mysterious space anomaly. This happens when we have a chiral anomaly and a gauge instanton.
