Prophecy

Prophecy involves a process in which one or more messages allegedly communicated to a prophet are then communicated to other people. Such messages typically involve divine inspiration, interpretation, or revelation of events to come (compare divine knowledge). Historically, clairvoyance has been used as an adjunct to prophecy.

Etymology

The English word "prophecy" (noun) in the sense of "function of a prophet" appeared in Europe from about 1225, from Old French profecie (12th century), and from Late Latin prophetia, Greek prophetia "gift of interpreting the will of God", from Greek prophetes (see prophet). The related meaning "thing spoken or written by a prophet" is from c. 1300, while the verb "to prophesy" is recorded by 1377.

The word prophecy comes from the Greek verb, προφημι (prophemi), which means “to say beforehand, foretell”; it is a combination of the Greek words, προ and φημι. The Greek prefix προ also means "before," "in front of," so etymologically προφημι means to speak in front of, as a spokesperson.

Implode (album)

Implode is an album by industrial group Front Line Assembly. The album was released through Metropolis on April 26, 1999.

Release

Implode was released on digipak CD and via Zoth Ommog on gatefold cover sleeve double vinyl with limited circulation of 2,000. The track "Torched" is featured in the 2002 horror film Resident Evil but not on the accompanying soundtrack.

Singles

Implode was followed by the release of two singles. The single Prophecy includes the original version, a radio edit and a remix of the title track. "Unknown Dreams" is also featured as radio edit. "Paralysis" is a non-album track. The second single, Fatalist, was released in different versions in Europe and North America. German label Zoth Ommog issued a four-track single that contains remixes of "Fatalist" (Rhys Fulber), "Retribution" (Front 242) and "Prophecy" (Haujobb) as well as non-album track "Deception". The six track version was released for the Scandinavian countries through Energy and in the United States through Metropolis. Additional tracks on this version are two remixes of "Fatalist" by Aqualite and Tribal Techno.

Hogwarts staff

The following fictional characters are staff members and denizens of Hogwarts in the Harry Potter books written by J. K. Rowling.

The staff and their positions

Notable teachers and staff members

The following are notable teachers and staff members who do not have their own articles or who are not listed in other articles.

Argus Filch

Argus Filch is the caretaker of Hogwarts. While he is not an evil character, he is ill-tempered, which makes him unpopular with the student body, and occasionally with other staff. His knowledge of the secrets and short-cuts of the castle is almost unparalleled, except perhaps by the Weasley twins, Voldemort himself, Harry, Ron and Hermione, and other users of the Marauder's Map. He tends to favour almost sadistically harsh punishments, leading to his alliance with Dolores Umbridge. He has an obsessive dislike of mud, animate toys, and all other things that might interfere with his creation of an immaculately clean and orderly Hogwarts. He is also portrayed as having a constant antagonism towards Peeves the poltergeist and often tells Dumbledore that Peeves should be thrown out of Hogwarts. He also likes to wander Hogwarts corridors at night, presumably in the hope of catching a student out of bed.

Precision

Significant figures

The significant figures of a number are digits that carry meaning contributing to its measurement resolution. This includes all digits except:

Significance arithmetic are approximate rules for roughly maintaining significance throughout a computation. The more sophisticated scientific rules are known as propagation of uncertainty.

Numbers are often rounded to avoid reporting insignificant figures. For example, it would create false precision to express a measurement as 12,345.00 kg (which has seven significant figures) if the scales only measured to the nearest gram and gave a reading of 12,345 kg (which has five significant figures) . Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement, for example to make them faster to pronounce in news broadcasts.

Precision and recall

In pattern recognition and information retrieval with binary classification, precision (also called positive predictive value) is the fraction of retrieved instances that are relevant, while recall (also known as sensitivity) is the fraction of relevant instances that are retrieved. Both precision and recall are therefore based on an understanding and measure of relevance. Suppose a computer program for recognizing dogs in scenes from a video identifies 7 dogs in a scene containing 9 dogs and some cats. If 4 of the identifications are correct, but 3 are actually cats, the program's precision is 4/7 while its recall is 4/9. When a search engine returns 30 pages only 20 of which were relevant while failing to return 40 additional relevant pages, its precision is 20/30 = 2/3 while its recall is 20/60 = 1/3.

So, in this case, precision is 'how useful the search results are', and recall is 'how complete the results are'.

In statistics, if the null hypothesis is that all and only the relevant items are retrieved, absence of type I and type II errors corresponds respectively to maximum precision (no false positive) and maximum recall (no false negative). The above pattern recognition example contained 7 − 4 = 3 type I errors and 9 − 4 = 5 type II errors. Precision can be seen as a measure of exactness or quality, whereas recall is a measure of completeness or quantity.
