Euclidean geometry has two fundamental types of measurements: angle and distance.

The fundamental types of measurements in Euclidean geometry are distances and angles, and both of these quantities can be measured directly by a surveyor.

In the parameterized post-Newtonian formalism ( PPN ), measurements of both the deflection of light and the gravitational time delay determine a parameter called γ, which encodes the influence of gravity on the geometry of space.

With the advent of exchange of goods, trades, and agricultures there arose a need for such measurements, and science ( arithmetic, geometry, mechanics, etc.

Composed of three books, it deals with the geometry of the sphere and its application in astronomical measurements and calculations.

The obvious disadvantage is relatively long analysis time, particularly when many elements are being analysed, not only because the elements are measured in sequence, but also because a certain amount of time is taken in readjusting the monochromator geometry between measurements.

Since projective geometry excludes compass constructions, there are no circles, no angles, no measurements, no parallels, and no concept of intermediacy.

Cherenkov counting in this experimental context is normally used for quick, rough measurements, since the geometry of the sample can create variations in the output.

To detect a fault, at least 5 measurements are required, and to isolate and exclude a fault, at least six measurements are required, however often more measurements are needed depending on the satellite geometry.

The HPL is calculated as a function of the RAIM threshold and the satellite geometry at the time of the measurements.

Taylor and his followers, who included the Astronomer Royal of Scotland Charles Piazzi Smyth ( 1819 – 1900 ), also found numerous apparent coincidences between the measurements of the pyramids and the geometry of the earth and the solar system.

In mathematics, the classes focus on geometry, substitutions and formulas, measurements and equations.

When the two curved cylinders have the same radius of curvature, R, this so-called ' crossed cylinders ' geometry is mathematically equivalent to the interaction between a flat surface and a sphere of radius R. Using the crossed cylinder geometry makes alignment much easier, enables testing of many different surface regions for better statistics, and also enables angle-dependent measurements to be taken.

It relies on the mathematical methods of spherical geometry and the measurements of astrometry.

Hand geometry readers measure a user's hand along many dimensions and compare those measurements to measurements stored in a file.

Photogrammetry is a digitization process that is able to generate highly accurate 3D geometry from measurements made in two or more photographs of the same object taken from different angles.

From there, the author rebuilds a great part of Euclidean geometry on top of his new proposed measurements, using only rational equivalences, which allow him to avoid any assumptions about the underlying scalar field.

Translated into the language of spacetime: the straight time-like lines that define a gravity-free inertial frame are deformed to lines that are curved relative to each other, suggesting that the inclusion of gravity necessitates a change in spacetime geometry.

The riding position is similar to the road racing position, but is ultimately dependent on the frame geometry of the bicycle and the handlebars used.

Comoving coordinates form a single frame of reference according to which the universe has a static geometry of three spatial dimensions.

The RDP is capable of rendering shaded, textured and depth buffered geometry to an arbitrary frame buffer in main memory.

:* projective geometry was emphasized as the unifying frame for all other geometries considered by him.

* Moving frame, in differential geometry

* Orthonormal frame, in Riemannian geometry

* Projective frame, in projective geometry

In Riemannian geometry and relativity theory, an orthonormal frame is a tool for studying the structure of a differentiable manifold equipped with a metric.

Road touring bicycles have a frame geometry designed to provide a comfortable ride and stable, predictable handling when laden with baggage, provisions for the attachment of fenders and mounting points for carrier racks and panniers.

Some touring bicycles, such as the Rivendell Atlantis and Surly Long Haul Trucker, offer frames designed for 26-inch ( ISO 559 ) wheels or for 700C wheels, with the frame geometry optimal for the selected wheel size.

It may also be described as a road racing bike fitted with heavier tires and slightly more relaxed frame geometry ( though still quicker than the average road touring bike ).

* Pantograph: a hinged frame that holds the collecting shoes against the wire in a fixed geometry.

He used the moving frame method with success only matched by its inventor ; he preferred in complex manifold theory to stay with the geometry, rather than follow the potential theory.

The suspension attachment must match the frame design in geometry, strength and rigidity.

In mathematics, a moving frame is a flexible generalization of the notion of an ordered basis of a vector space often used to study the extrinsic differential geometry of smooth manifolds embedded in a homogeneous space.

The Frenet-Serret frame plays a key role in the differential geometry of curves, ultimately leading to a more or less complete classification of smooth curves in Euclidean space up to congruence.

In that year the 500 cc model was deleted from the lineup and an even bigger 900 cc model was introduced, along with improvements to the electrical system and frame geometry.

The differential geometric properties of a curve ( length, Frenet frame and generalized curvature ) are invariant under reparametrization and therefore properties of the equivalence class. The equivalence classes are called C < sup > r </ sup > curves and are central objects studied in the differential geometry of curves.

The suspension is a lightweight aluminium front sub frame with hollow castings with independent double wishbone incorporating anti-dive geometry, coil springs, anti-roll bar and monotube adaptive dampers in the front and independent double wishbones with anti-squat and anti-lift geometry, coil springs, anti-roll bar and monotube adaptive dampers in the rear.

In the mathematical field of projective geometry, a projective frame is an ordered collection of points in projective space which can be used as reference points to describe any other point in that space.

Some racing bicycles, however, have a top tube that slopes down towards the rear of the bicycle ; the " compact " frame geometry was popularized by Giant.

These have much in common with a competitive racing bicycle, but the frame geometry is relaxed to make the bicycle more comfortable over long distances, though less effective for short bursts of speed ; as such, they usually have more gear combinations and fewer hi-tech racing features.
