Decauville Railway At Diégo Suarez
The Diégo Suarez Decauville railway was a long gauge military railway from Antsiranana, Antsirane to Sakaramy in Madagascar. Construction and route The gauge Decauville railway was built in 1900 from Antsirane (now Antsiranana) to the Tunisian Fountain (''Fontaine Tunisienne'') at today's STAR factory. It started at the port and ran on the ''Rue Gouraud'' and the ''Boulevard Bazeilles'' up to the ''Cercle Français'' (now ''Suarez Art'') and up the ''Boulevard Militaire''. It turned into the ''Boulevard de Sakaramy'' at the height of ''Camp Lubert'', from where it led past the present town hall to ''l'Octroi'' and the Tunisian Fountain. At the end of 1900, it was extended from the Tunisian Fountain via Antanamitara and Andranomanitra to the junction of today's road to Joffreville. The route was designed by Captain Brunet to generally follow the terrain and thus to avoid large earthworks. At the Gorge of Antanamitara, a curve with a radius of only was needed. A deep cut ...

Antsiranana
Antsiranana ( mg, Antsiran̈ana ), named Diego-Suárez prior to 1975, is a city in the far north of Madagascar. Antsiranana is the capital of Diana Region. It had an estimated population of 115,015 in 2013. History The bay and city originally used the name ''Diego-Suárez'', named after Diogo Soares, a Portuguese navigator who visited the bay in 1543–44. In the 1880s, the bay was coveted by France, which desired it as a coaling station for steamships. After the first Franco-Hova War, Queen Ranavalona III signed a treaty on December 17, 1885, granting France a protectorate over the bay and surrounding territory, as well as the islands of Nosy-Be and Ste. Marie de Madagascar. The colony's administration was subsumed into that of Madagascar in 1896. The Second Pacific Squadron of Imperial Russia anchored and was resupplied at Diego-Suárez on its way to the Battle of Tsushima in 1905. In 1942, Diego-Suárez was the primary objective of Operation Ironclad, the starting point ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decauville Railway Diego Suarez – Le Camp D’Ambre At Camp Lubert And Boulevard Sakaramy
Decauville () was a manufacturing company which was founded by Paul Decauville (1846–1922), a French pioneer in industrial railways. Decauville's major innovation was the use of ready-made sections of light, narrow gauge track fastened to steel sleepers; this track was portable and could be disassembled and transported very easily. The first Decauville railway used gauge; Decauville later refined his invention and switched to and gauge. History Origins In 1853 Paul Decauville's father, Amand, created a boilermaking workshop on the family farm in order to set up distilleries on the farms to the east of Paris. In 1864, Amand asked his eldest son, Paul, to come and help him following health problems. Very quickly, the latter seeks to improve the functioning of the estate. Very developed under the Second Empire in the northern half of France, the production of sugar beet and its refining into sugar, is linked to that of alcoholic products such as fuel. Amand will therefor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Former Buildings And Structures In Madagascar
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ad ...

600 Mm Gauge Railways
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tram Transport
A tram (called a streetcar or trolley in North America) is a rail vehicle that travels on tramway tracks on public urban streets; some include segments on segregated right-of-way. The tramlines or networks operated as public transport are called tramways or simply trams/streetcars. Many recently built tramways use the contemporary term light rail. The vehicles are called streetcars or trolleys (not to be confused with trolleybus) in North America and trams or tramcars elsewhere. The first two terms are often used interchangeably in the United States, with ''trolley'' being the preferred term in the eastern US and ''streetcar'' in the western US. ''Streetcar'' or ''tramway'' are preferred in Canada. In parts of the United States, internally powered buses made to resemble a streetcar are often referred to as "trolleys". To avoid further confusion with trolley buses, the American Public Transportation Association (APTA) refers to them as "trolley-replica buses". In the United ...

Exposition Universelle (1889)
The Exposition Universelle of 1889 () was a world's fair held in Paris, France, from 5 May to 31 October 1889. It was the fourth of eight expositions held in the city between 1855 and 1937. It attracted more than thirty-two million visitors. The most famous structure created for the Exposition, and still remaining, is the Eiffel Tower. Organization The Exposition was held to celebrate the 100th anniversary of the Storming of the Bastille, which marked the beginning of French Revolution, and was also seen as a way to stimulate the economy and pull France out of an economic recession. The Exposition attracted 61,722 official exhibitors, of whom twenty-five thousand were from outside of France. Admission price Admission to the Exposition cost forty centimes, at a time when the price of an "economy" plate of meat and vegetables in a Paris cafe was ten centimes. Visitors paid an additional price for several of the Exposition's most popular attractions. Climbing the Eiffel Towe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diego Suarez - Chemin De Fer D'Antsirane Au Cap D'Ambre (cropped)
Diego is a Spanish masculine given name. The Portuguese equivalent is Diogo. The name also has several patronymic derivations, listed below. The etymology of Diego is disputed, with two major origin hypotheses: ''Tiago'' and ''Didacus''. Etymology ''Tiago'' hypothesis Diego has long been interpreted as variant of ''Tiago'' (Brazilian Portuguese: '' Thiago''), an abbreviation of ''Santiago'', from the older ''Sant Yago'' "Saint Jacob", in English known as Saint James or as ''San-Tiago''. This has been the standard interpretation of the name since at least the 19th century, as it was reported by Robert Southey in 1808 and by Apolinar Rato y Hevia (1891). The suggestion that this identification may be a folk etymology, i.e. that ''Diego'' (and ''Didacus''; see below) may be of another origin and only later identified with ''Jacobo'', is made by Buchholtz (1894), though this possibility is judged as improbable by the author himself. ''Didacus'' hypothesis In the later 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shuttle Radar Topography Mission
The Shuttle Radar Topography Mission (SRTM) is an international research effort that obtained digital elevation models on a near-global scale from 56°S to 60°N, to generate the most complete high-resolution digital topographic database of Earth prior to the release of the ASTER GDEM in 2009. SRTM consisted of a specially modified radar system that flew on board the Space Shuttle Endeavour during the 11-day STS-99 mission in February 2000. The radar system was based on the older '' Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar'' (SIR-C/X-SAR), previously used on the Shuttle in 1994. To acquire topographic data, the SRTM payload was outfitted with two radar antennas. One antenna was located in the Shuttle's payload bay, the other – a critical change from the SIR-C/X-SAR, allowing single-pass interferometry – on the end of a 60-meter (200-foot) mast that extended from the payload bay once the Shuttle was in space. The technique employed is known as interferomet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Digital Elevation Model
A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid. A "global DEM" refers to a discrete global grid. DEMs are used often in geographic information systems (GIS), and are the most common basis for digitally produced relief maps. A digital terrain model (DTM) represents specifically the ground surface while DEM and DSM may represent tree top canopy or building roofs. While a DSM may be useful for landscape modeling, city modeling and visualization applications, a DTM is often required for flood or drainage modeling, land-use studies, geological applications, and other applications, and in planetary science. Terminology There is no universal usage of the terms ''digital elevation model'' (DEM), ''digital terrain model'' (DTM) and ''digital surface model'' (DSM) in scientific literature. In most cases the term ''digital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
