An artefact is an object that has been made by a person. Archaeologists use artefacts to learn about the past. go back
The appearance in the CT image of details not present in the scanned object. The main components of structured noise are due to a form of partial volume effect and to beam hardening. Both effects usually result in streaking artefacts, which are observed in regions of high contrast when there is a sharp discontinuity in object density, such as at air-tissue, air-bone and metal-tissue boundaries. Streaking will also arise from mechanical misalignment within the scanner and, in clinical practice, from patient motion and the use of high-density contrast media.
A humanly modified aspect of the environment. It usually refers to objects that are made by people but the concept also incorporates farmed land, fishing weirs, etc.
Any object which is physically modified by humans.
An item of human manufacture, normally applied only to the products of previous culture. Artefacts may or may not be buried by sediment. Examples bone or stone tools, engraving, painting.
a man-made object taken as a whole
a tool which enables the energies of the context to be competitively accessed
a unique product which implies that its development is not a mechanistic process but requires some degree of human creativity
Any product made by human hands or caused to be made through human actions.
Any portable object used, modified or made by humans. For example pottery, weapons and coins.
Any moveable object that has been used, modified or manufactured by humans.
An object or part of an object which has been used or created by a human and provides physical clues to the activity carried out by humans in the area of discovery (This can range from Pottery, Metalwork, Woodwork, Worked Stones through to mortar samples) (See Ecofact) assemblage: a group of artefacts found together in a single context such as a grave or pit.
any object made or modified by human kind. In the Australian context, stone tools especially.
An object created by an artistic or a design process; a work of art. The question of what constitutes a work of art is a fluid one. To give an example: a gravure print can be considered an original work, but the same print can also be included within the larger context of a portfolio, in which case the portfolio may well be regarded as the art object. The same print can also be a separate framed picture, in which case the picture with its frame is the artefact. Likewise, it is open to question whether individual prints of an edition are different works or versions of one and the same work of art.
