## Conceptual system

A conceptual system is a system that is composed of non-physical objects, i.e. ideas or concepts. In this context a system is taken to mean "an interrelated, interworking set of objects".

## AeroVironment Global Observer

The AeroVironment Global Observer is a concept for a high-altitude, long endurance unmanned aerial vehicle, designed by AeroVironment to operate as a stratospheric geosynchronous satellite system with regional coverage. Two Global Observer aircraft, each flying for up to a week at an altitude of 55.000 to 65.000 feet 17.000 to 20.000 m, could alternate coverage over any area on the earth, providing a platform for communications relays, remote sensing, or long-term surveillance. In addition to flying above weather and above other conventional aircraft, operation at this altitude permits com ...

## Systems art

Systems art is art influenced by cybernetics, and systems theory, that reflects on natural systems, social systems and social signs of the art world itself. Systems art emerged as part of the first wave of the conceptual art movement extended in the 1960s and 1970s. Closely related and overlapping terms are Anti-form movement, Cybernetic art, Generative Systems, Process art, Systems aesthetic, Systemic art, Systemic painting and Systems sculptures.

## Axiomatic system

In mathematics, an axiomatic system is any set of axioms from which some or all axioms can be used in conjunction to logically derive theorems. A theory is a consistent, relatively-self-contained body of knowledge which usually contains an axiomatic system and all its derived theorems. An axiomatic system that is completely described is a special kind of formal system. A formal theory is an axiomatic system that describes a set of sentences that is closed under logical implication. A formal proof is a complete rendition of a mathematical proof within a formal system.

## Boehm system

Prior to the development of the Boehm system, flutes were most commonly made of wood, with an inverse conical bore, eight keys, and tone holes the openings where the fingers are placed to produce specific notes that were small in size, and thus easily covered by the fingertips. Boehms work was inspired by an 1831 concert in London, given by soloist Charles Nicholson who, with his father in the 1820s, had introduced a flute constructed with larger tone holes than were used in previous designs. This large-holed instrument could produce greater volume of sound than other flutes, and Boehm set ...

## Comstock–Needham system

The Comstock–Needham system is a naming system for insect wing veins, devised by John Comstock and George Needham in 1898. It was an important step in showing the homology of all insect wings. This system was based on Needhams pretracheation theory that was later discredited by Frederic Charles Fraser in 1938.
