Missile Guidance
Missile guidance refers to a variety of methods of guiding a missile or a guided bomb to its intended target. The missile's target accuracy is a critical factor for its effectiveness. Guidance systems improve missile accuracy by improving its Probability of Guidance (Pg). These guidance technologies can generally be divided up into a number of categories, with the broadest categories being "active", "passive", and "preset" guidance. Missiles and guided bombs generally use similar types of guidance system, the difference between the two being that missiles are powered by an onboard engine, whereas guided bombs rely on the speed and height of the launch aircraft for propulsion. History The concept of unmanned guidance originated at least as early as World War I, with the idea of remotely guiding an airplane bomb onto a target, such as the systems developed for the first powered drones by Archibald Low (The Father of Radio Guidance). In World War II, guided missiles were first d ...

Clos Network
In the field of telecommunications, a Clos network is a kind of multistage circuit-switching network which represents a theoretical idealization of practical, multistage switching systems. It was invented by Edson Erwin in 1938 and first formalized by Charles Clos () in 1952. By adding stages, a Clos network reduces the number of crosspoints required to compose a large crossbar switch. A Clos network topology (diagrammed below) is parameterized by three integers ''n'', ''m'', and ''r'': ''n'' represents the number of sources which feed into each of ''r'' ingress stage crossbar switches; each ingress stage crossbar switch has ''m'' outlets; and there are ''m'' middle stage crossbar switches. Circuit switching arranges a dedicated communications path for a connection between endpoints for the duration of the connection. This sacrifices total bandwidth available if the dedicated connections are poorly utilized, but makes the connection and bandwidth more predictable, and only intr ...

Clos (vineyard)
A clos (French 'enclosure') is a walled vineyard. Walled vineyards protected the grapes from theft and may improve the mesoclimate. They were often the vineyards of Cistercian monasteries. The word is often used in the name of famous wines even when the wall no longer exists. By country France * Bordeaux: Château Léoville-Las Cases, Clos Haut-Peyraguey, Clos Fourtet, Clos des Jacobins, Clos de l'Oratoire, Clos de Plince, Clos Saint-Martin * Burgundy: Clos Napoléon ( Fixin), Chambertin-Clos de Bèze, Clos de Tart, Clos des Lambrays, Clos de la Roche, Clos Saint-Denis, La Romanée together with La Romanée-Conti, Clos de Vougeot, Clos des Réas (Vougeot), Corton-Clos du Roi, Clos des Ursules, Clos des Mouches (Beaune), Clos des Épeneaux ( Pommard), Clos du Val ( Auxey-Duresses), Clos des Chênes ( Volnay), Montrachet * Champagne: Clos des Goisses ( Mareuil-sur-Aÿ), Clos du Mesnil (Le Mesnil-sur-Oger; see Champagne Krug), Clos Saint Hilaire ( Mareuil-sur-Aÿ; see Billeca ...

Cul-de-sac
A dead end, also known as a cul-de-sac (, from French for 'bag-bottom'), no through road or no exit road, is a street with only one inlet or outlet. The term "dead end" is understood in all varieties of English, but the official terminology and traffic signs include many different alternatives. Some of these are used only regionally. In the United States and other countries, ''cul-de-sac'' is often not an exact synonym for ''dead end'' and refers to dead ends with a circular end, allowing for easy turning at the end of the road. In Australia and Canada, they are usually referred to as a ''court'' when they have a bulbous end. Dead ends are added to road layouts in urban planning to limit through-traffic in residential areas. While some dead ends provide no possible passage except in and out of their road entry, others allow cyclists, pedestrians or other non-automotive traffic to pass through connecting easements or paths, an example of filtered permeability.
