geometric

It is presumed that this negative head was associated with some geometric factor of the assembly, since different readings were obtained with the same fluid and the only apparent difference was the assembly and disassembly of the apparatus.

The term " arithmetic mean " is preferred in mathematics and statistics because it helps distinguish it from other means such as the geometric and harmonic mean.

The Latin word came from Greek ἄβαξ abax " board strewn with sand or dust used for drawing geometric figures or calculating "( the exact shape of the Latin perhaps reflects the genitive form of the Greek word, ἄβακoς abakos ).

* Spatial analysis – the study of entities using geometric or geographic properties

Particles cannot be restricted to a geometric point in space, since this would require an infinite particle momentum.

In the field of computer graphics, an anisotropic surface will change in appearance as it is rotated about its geometric normal, as is the case with velvet.

In his youth he went to the continent and taught mathematics in Paris, where he published or edited, between the years 1612 and 1619, various geometric and algebraic tracts.

In Aristotle this is categorized as the difference between ' arithmetic ' and ' geometric ' ( i. e. proportional ) equality.

The fundamental objects of study in algebraic geometry are algebraic varieties, geometric manifestations of solutions of systems of polynomial equations.

Algebraic geometry now finds application in statistics, control theory, robotics, error-correcting codes, phylogenetics and geometric modelling.

The Miesian formal language of geometric grids employed in the buildings was also used by Aalto for other sites in Helsinki, including the Enso-Gutzeit building ( 1962 ), the Academic Bookstore ( 1962 ) and the SYP Bank building ( 1969 ).

Porter and Duff gave a geometric interpretation of the alpha compositing formula by studying orthogonal coverages.

This contrasts with the synthetic approach of Euclidean geometry, which treats certain geometric notions as primitive, and uses deductive reasoning based on axioms and theorems to derive truth.

Coordinates, variables, and equations were subsidiary notions applied to a specific geometric situation.

The eleventh century Persian mathematician Omar Khayyám saw a strong relationship between geometry and algebra, and was moving in the right direction when he helped to close the gap between numerical and geometric algebra with his geometric solution of the general cubic equations, but the decisive step came later with Descartes.

Fermat always started with an algebraic equation and then described the geometric curve which satisfied it, while Descartes starts with geometric curves and produces their equations as one of several properties of the curves.

In analytic geometry, geometric notions such as distance and angle measure are defined using formulas.

Transformations can be applied to any geometric equation whether or not the equation represents a function.

For two geometric objects P and Q represented by the relations P ( x, y ) and Q ( x, y ) the intersection is the collection of all points ( x, y ) which are in both relations.

Dürer's geometric constructions include helices, conchoids and epicycloids.

In typography, Dürer depicts the geometric construction of the Latin alphabet, relying on Italian precedent.

* Wen-Tsun Wu Work in geometric theorem proving: Wu's method, Herbrand Award 1997

The true position ( or geometric position ) is the direction of the straight line between the observer and star at the instant of observation.
