Control Point (mathematics)
In computer-aided geometric design a control point is a member of a set of Point (geometry), points used to determine the shape of a spline curve or, more generally, a computer representation of surfaces, surface or higher-dimensional object. For Bézier curves, it has become customary to refer to the -vectors in a parametric representation \sum_i \mathbf p_i \phi_i of a curve or surface in -space as control points, while the Scalar field, scalar-valued functions , defined over the relevant parameter domain, are the corresponding weight function, ''weight'' or ''blending functions''. Some would reasonably insist, in order to give intuitive geometric meaning to the word "control", that the blending functions form a partition of unity, i.e., that the are nonnegative and sum to one. This property implies that the curve lies within the convex hull of its control points.. This is the case for Bézier's representation of a polynomial curve as well as for the B-spline representation ...

Control Point (orienteering)
A control point (CP, also control and checkpoint) is a marked waypoint used in orienteering and related sports such as rogaining and adventure racing. It is located in the competition area; marked both on an orienteering map and in the terrain, and described on a control description sheet. The control point must be identifiable on the map and on the ground. A control point has three components: a high visibility item, known as a flag or kite; an identifier, known as a control code; and a recording mechanism for contestants to record proof that they visited the control point. The control point is usually temporary, except on a permanent orienteering course. For events held under International Orienteering Federation (IOF) rules the kite has a triangular form with each face being about 30  cm x 30  cm and coloured white and orange. Most national governing bodies, and related sports use the same design. The earlier specification used white and red. The location of co ...

Control Point (rail)
Rail terminology is a form of technical terminology. The difference between the American term ''railroad'' and the international term ''railway'' (used by the International Union of Railways and English-speaking countries outside the United States) is the most significant difference in rail terminology. These and other terms have often originated from the parallel development of rail transport systems in different parts of the world. In English-speaking countries outside the United Kingdom, a mixture of US and UK terms may exist. Various global terms are presented here. Where a term has multiple names, this is indicated. The abbreviation "UIC" refers to standard terms adopted by the International Union of Railways in its official publications and thesaurus. 0–9 A B ...

Counting Point
In logistics, a counting point (CP; also known as a status point, data acquisition point, check point, or control point) is a certain spot designated for planning, controlling, and monitoring material flow items (e.g. single parts, assembly groups, final products, bins, racks, containers, and freight carriers). Installation If the production and material flow gets more and more complex then more counting points must be installed in the process of transport, shipping, and manufacturing. Especially check points for quality control and quality assurance can be used outstandingly as counting points but also data acquisition points in material handling processes. For better planning and monitoring of material flow items it is helpful to order all counting points in such a way that the requirements of an ideal Boolean Interval (mathematics) Algebra can be fulfilled. Boolean intervals are half-opened and a counting point lays always inside at the beginning and the ending lays outside and ...

Geodetic Control Point
A geodetic control network (also geodetic network, reference network, control point network, or control network) is a network, often of triangles, which are measured precisely by techniques of terrestrial surveying or by satellite geodesy. A geodetic control network consists of stable, identifiable points with published datum values derived from observations that tie the points together. Classically, a control is divided into horizontal (X-Y) and vertical (Z) controls (components of the control), however with the advent of satellite navigation systems, GPS in particular, this division is becoming obsolete. Many organizations contribute information to the geodetic control network. The higher-order (high precision, usually millimeter-to-decimeter on a scale of continents) control points are normally defined in both space and time using global or space techniques, and are used for "lower-order" points to be tied into. The lower-order control points are normally used for engine ...

Port Of Entry
In general, a port of entry (POE) is a place where one may lawfully enter a country. It typically has border security staff and facilities to check passports and visas and to inspect luggage to assure that contraband is not imported. International airports are usually ports of entry, as are road and rail crossings on a land border. Seaports can be used as ports of entry only if a dedicated customs presence is posted there. The choice of whether to become a port of entry is up to the civil authority controlling the port. Airport of entry An airport of entry (AOE) is an airport that provides customs and immigration services for incoming flights. These services allow the airport to serve as an initial port of entry for foreign visitors arriving in a country. Terminology The word "international" in an airport's name usually means that it is an airport of entry, but many airports of entry do not use it. Airports of entry can range from large urban airports with heavy scheduled pas ...

Border Checkpoint
A border checkpoint is a location on an international border where travelers or goods are inspected and allowed (or denied) passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings (e.g. the Schengen Agreement). Land border checkpoints (land ports of entry) can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry. Checkpoints generally serve two purposes: * To prevent entrance of individuals who are either undesirable (e.g. criminals or others who pose threats) or simply unauthorized to enter. * To prevent entrance of goods that are illegal or subject to restriction, or to collect tariffs. Checkpoints are usually staffed by a uniformed service (sometimes referred to as customs ...

Kilometre Zero
In many countries, kilometre zero (also written ''km 0'') or similar terms in other languages (also known as zero mile marker, zero milepost, control stations or control points) denote a particular location (usually in the nation's capital city) from which distances are traditionally measured, this is also used for measuring distances between different countries around the world. Historically, they were markers where drivers could set their odometers to follow the directions in early guide books. One such marker is the Milliarium Aureum ("Golden Milestone") of the Roman Empire, believed to be the literal origin for the maxim that " all roads lead to Rome". Countries Argentina Argentina marks kilometre zero with a monolith in Plaza Congreso in Buenos Aires. The work of the brothers Máximo and José Fioravanti, the structure was placed on the north side of Plaza Lorea on October 2, 1935; it was moved to its present location on May 18, 1944. An image of Our Lady of Luján (hon ...
