The Catalan vault (Catalan: "volta catalana" ), also called tile vault, Catalan turn, Catalan arch or timbrel vault, is a type of low arch made of plain bricks often used to make a structural floor surface.
 It is traditionally constructed by laying bricks lengthwise over a wood form or "centering", making it a much gentler curve than has generally been produced by other methods of construction.
The Catalan manual alphabet is used in Catalan Sign Language.
 It is one of the oldest manual alphabets still in use.
 However, it wasn't officially recognized as one of Catalunya's official languages until 2010, when Law 17/2010, 3 of June, of the Catalan sign language (LSC) was approved by the government.
 The Catalan manual alphabet is single-handed and is extremely similar to the Spanish manual alphabet.
 As a result, people who use Spanish sign language can understand approximately up to 80% of the Catalan sign language.
Cobi was the official mascot of the 1992 Summer Olympics in Barcelona, Spain.
 He is a Catalan Sheepdog in Cubist style inspired by the interpretations of Picasso of a masterpiece from Velázquez, "Las Meninas".
 Cobi was designed by Javier Mariscal.
 The mascot was unveiled to the public in 1987.
 His name was derived from the Barcelona Olympic Organising Committee (COOB).
Catalan Countries (Catalan: "Països Catalans" , ] , ] ) refers to those territories where the Catalan language is natively spoken.
 They include the Spanish regions of Catalonia, Valencia, the Balearic Islands and parts of Aragon, as well as Roussillon in France, the Principality of Andorra, and the city of Alghero in Sardinia (Italy).
 In the context of Catalan nationalism, the term is sometimes used in a more restricted way to refer to just Catalonia, Valencia and the Balearic Islands.
 The Catalan Countries do not correspond to any present or past political or administrative unit, though most of the area belonged to the Crown of Aragon in the Middle Ages, in which Catalan was an official and predominant language.
 Smaller parts of Valencia (Spanish) and Catalonia (Occitan) are not Catalan-speaking.
The Catalan sheepdog (Catalan: "Gos d'atura català" , Spanish: "Pastor catalán" ) is a breed of Catalan pyrenean dog used as a sheepdog.
 This dog is bred in Europe, especially in Spain, Finland, Germany, and Sweden.
The Catalan Talgo was an international express train introduced in 1969 that linked Geneva, Switzerland, with Barcelona, Spain.
 It was named after the Spanish region Catalonia and the Talgo equipment it used.
 It was an extension and upgrading of a predecessor train, "Le Catalan", a first-class-only French (SNCF) "Rapide" train that had been in operation since 1955 but running only between Geneva and the stations nearest the Spanish-French border, connecting with a second-class-only "autorail" trainset to and from Barcelona.
 The national railway network of Spain, "Red Nacional de los Ferrocarriles Españoles" (RENFE), was using Iberian gauge for all of its main lines, while those of France and Switzerland use standard gauge.
 As a result of this break-of-gauge, train journeys between Geneva and Barcelona consisted of two separate parts, with travelers having to change from a French to a Spanish train or vice versa at the border—at Portbou (alternatively written as Port Bou) on southbound trains and at Cerbère on northbound trains.
 In 1968, this was resolved with the introduction of the Talgo III RD trainsets, which featured variable gauge wheelsets.
 At Portbou station, the wheel spacing of each passenger carriage was adjusted by a gauge changer for the difference in gauge, and passengers no longer had to change trains.
 After successful test runs, the "Catalan" was extended from Port Bou to Barcelona as a through train on 1 June 1969, becoming the "Catalan Talgo" and upgraded to a Trans Europ Express (TEE).
 Most other rail journeys through this border crossing continued to require a change of train at Cerbère station or at Port Bou, as most trains did not use Talgo III RD trainsets.
A delegate is a form of type-safe function pointer used by the Common Language Infrastructure (CLI).
 Delegates specify a method to call and optionally an object to call the method on.
 Delegates are used, among other things, to implement callbacks and event listeners.
 A delegate object encapsulates a reference to a method.
 The delegate object can then be passed to code that can call the referenced method, without having to know at compile time which method will be invoked.
The Braque de l’Ariège, translated into English as the Ariege Pointing Dog or Ariege Pointer, is a breed of dog, a French hunting dog of pointing gun dog type.
 The breed is kept primarily as a hunting dog, not as a pet or showdog.
In the C programming language, as of the C99 standard, codice_1 is a keyword that can be used in pointer declarations.
 The codice_1 keyword is a declaration of intent given by the programmer to the compiler.
 It says that for the lifetime of the pointer, only the pointer itself or a value directly derived from it (such as ) will be used to access the object to which it points.
 This limits the effects of pointer aliasing, aiding optimizations.
 If the declaration of intent is not followed and the object is accessed by an independent pointer, this will result in undefined behavior.
 The use of the codice_1 keyword in C, in principle, allows non-obtuse C to achieve the same performance as the same program written in Fortran.
The Himalayan Sheepdog, also referred to as the Bhote Kukur or Bhotia, is a livestock guardian dog that originated from Nepal.
 This mountain dog breed is closely similar to Indian Mastiff and the Tibetan Mastiff and may be related to the long-haired Kinnaur Sheepdog of Tibet.
 Naturally, Himalayan Sheepdogs enjoy outdoor lifestyles and are rarely seen beyond the regions of India and Nepal.
 As a powerful and robust breed, the Himalayan Sheepdog is mainly used for herding purposes.
 The Himalayan Sheepdog is regionally popular as both a loyal companion as well as a working dog.

Question: Are the Catalan Sheepdog and Ariege Pointer used for the same purpose?
Answer: no
