In mathematics and engineering , the S plane is the name for the complex plane on which Laplace transform s are graphed. It is a mathematical domain where, instead of viewing processes in the time domain modelled with time based functions, they are viewed as equations in the frequency domain . It is used as a graphical analysis tool in engineering and physics. A real time function is translated into the s plane by taking the integral of the function, multiplied by math e st math from math infty math to math infty math , where s is a complex number . math int infty infty f t e st ,dt math One way to understand what this equation is doing is to remember how Fourier analysis works. In Fourier analysis , harmonic sine and cosine waves are multiplied into the signal, and the resultant integration provides indication of a signal present at that frequency i.e. the signal s energy at a point in the frequency domain . The s transform does the same thing, but more generally. The e sup st sup not only catches frequencies, but also the real e sup t sup effects as well. s transforms therefore cater not only for frequency response, but decay effects as well. For instance, a damped sine wave can be modeled correctly using s transforms. s transforms are commonly known as Laplace transform s. In the s plane, multiplying by s has the effect of differentiating in the corresponding real time domain. Dividing by s integrates. Analysing the complex number complex roots of an s plane equation and plotting them on an Argand diagram , can reveal information about the frequency response and stability of a real time system.

For a vertically polarized antenna, the E plane usually coincides with the vertical elevation plane. For a horizontally polarized antenna, the E Plane usually coincides with the horizontal azimuth plane. E plane and H plane should be 90 deg apart.

Unreferenced stub auto yes date December 2009 In 3D computer graphics , the image plane is that Plane mathematics plane in the world which is identified with the plane of the monitor. If one makes the analogy of taking a photograph to rendering a 3D image, the surface of the film is the image plane. In this case, the viewing transformation is a 3D projection projection that maps the world onto the image plane. A rectangular region of this plane, called the viewing window or viewport , maps to the monitor. This establishes the mapping between pixels on the monitor and points or rather, rays in the 3D world.

In projective geometry a Desarguesian plane , named after G rard Desargues , is a plane in which Desargues theorem holds. The ordinary real projective plane is a Desarguesian plane. More generally any projective plane over a division ring is Desarguesian, and conversely Hilbert showed that any Desarguesan projective plane is the projective plane over some division ring. The division ring is commutative if and only if the projective plane satisfies Pappus s hexagon theorem . In particular all finite Desarguesian planes satisfy Pappus s theorem, but there are some infinite ones that do not. There are many examples of non Desarguesian plane s where Desargues s theorem does not hold, such as the Moulton plane . geometry stub References http www.ams.org notices 200710 tx071001294p.pdf Ch.

Image hoevl.jpg thumb Smoothing plane Image Garrett Wade Paragon No. 4 Smoothing Plane.jpg thumb A modern, iron bodied, No. 4 Smoothing Plane A smoothing plane or smooth plane is a type of bench plane tool plane used in woodworking . The smoothing plane is typically the last plane used on a wood surface when used properly, the finish it gives will be far superior to that made by sandpaper or scrapers. The smooth finish is the result of planing the wood off in strips, rather than by successive buffing and scratching. The smoothing plane is typically 8 to 10 inches long. The throat may be adjusted to a tight opening so as to allow only a very fine shaving and to reduce tearout of the grain to a minimum. The smooth plane is held with both hands. ref Hand Planes Reprint from Handwork In Wood by William Noyes ref The Plane tool Parts of a plane iron of the smoothing plane is generally sharpened straight across or with a slightly Wiktionary arch arch ed cutting Wiktionary edge edge or at least with rounded corners to prevent unsightly Groove engineering groove s from being gouged in the wood surface as it is planed.

Unreferenced date December 2009 Image Jack Plane No. 5.jpg thumb 200px A modern, Bailey type Jack Plane A jack plane is the general purpose bench plane tool plane , used for general smoothing of the edges, sizing of wood and edge joining jointing edges. Jack planes are about 12 15 inches long, and the blade can have either a slightly circled edge for smoothing stock, or a curved edge for jointing stock. In preparing stack, the jack plane is used after the scrub plane and before the jointer plane and smooth plane . The name is related to the saying jack of all trades . Jack planes perform both the work of smooth planes and Jointer plane trying planes . A jack plane came to be referred to as a No. 5 plane or a Bailey pattern No. 5, at the end of the 19th century. Prior to that, all but the blade was made of wood in bench planes. The No. nomenclature originally used by Stanley Tools to label its Bailey pattern plane products continues to identify planes made by various manufacturers. Not all manufacturers of the era had the same number scheme for their planes. Millers Fall and Sargent had different numbers to refer to the same planes.

Plane symmetry means a symmetry of a pattern in the Euclidean plane that is, a transformation of the plane that carries any directioned lines to lines and preserves many different distances. If one has a pattern in the plane, the set of plane symmetries that preserve the pattern forms a group mathematics group . The groups that arise in this way are plane symmetry groups and are of considerable mathematical interest. A symmetry plane is a three dimensional object s symmetry axe. There are several kinds of plane symmetry groups Reflection group s. These are plane symmetry groups that are generated by reflections, possibly limited to reflections in lines through the origin. Rotation group s. These groups consist of rotations around a point. Translation group s. Symmetries of geometrical figure s. Some of these are reflection groups, e.g., the group of symmetries of the square geometry square or the rectangle . The symmetry group of a swastika or any similar figure without an axis of symmetry is a rotation group. Category Euclidean geometry geometry stub ... more details
