The narrow-gauge railroad, which has a two-foot-wide track instead of the standard gauge of four feet eight and a half inches, originated in the Maine hinterlands in the late 19th century and was used to transport lumber from otherwise impassable areas.
The tide gauge consisted of three pressure sensors (see Section 2).
Construction began on May 13 , 1822 using both malleable iron rails (for two-thirds the distance) and cast iron and set at a track gauge of 1,422 mm (4 feet 8 inches).
A truer gauge of the two sides' real power may come Wednesday, the fifth anniversary of the day United States troops captured the Iraqi capital, when Mr. Sadr has called for a million of his followers to march through the streets of Baghdad to protest the continuing presence of American forces in Iraq.
In 1957 a government study concluded that the existing line between Tokyo and Ōsaka, built to the historic Japanese track gauge of 1,067 mm (3 feet 6 inches), was incapable of upgrading to the needs of the densely populated and industrialized Tōkaidō coastal belt between the two cities.
It was the deliberate policy of Spain, and thereby of Portugal, to adopt a nominal gauge of 1,676 mm (5 feet 6 inches) so as to be distinct from France, a neighbour who on several occasions during the preceding century had interfered in Spanish affairs.
The vertical black dashed line indicates a tide gauge error of zero.
A double ball gauge consists of two precision metal spheres and a telescoping bar installed on a grating ruler that can detect the displacement (shown in Figure 13).
Results are shown in Table 2. Postural performance during quiet standing was investigated through the center of pressure (CoP) displacements recorded using a force platform (principle of strain gauge) consisting of two dynamometric clogs (Standards by Association Française de Posturologie; produced by TechnoConcept, Céreste, France).
Furthermore, we wanted to gauge the opinions of three groups that received a heavy focus throughout the course of the 2016 election: America's working class, Republicans, and women.
