    Some 15 TSS schemes can be found in this area: in the Red Sea is traffic using the Suez Channel while in the Persian Gulf much of the traffic comprises the (large) oil and gas tankers to Iran and Iraq. All TSS's here are governed by the IMO, except the Approaches to Yanbu which is the responsibility of the Kingdom of Saudi Arabia. Gulf of Suez

    Other TSSs are in place off Land's End and around Ouessant . Well-known TSS locations include the English Channel, German Bight, Singapore, and Cape Horn. The Dover Strait/Détroit du Pas de Calais was the first International Maritime Organisation (IMO) approved traffic separation scheme in the world in 1967. [2] [3]

    At the lower end, TSS relies on a cut-off established by properties of the filter being used. At the upper end, the cut-off should be the exclusion of all particulates too large to be "suspended" in water. However, this is not a fixed particle size but is dependent upon the energetics of the situation at the time of sampling: moving water ...

    An Ordnance Survey cut mark in the UK Occasionally a non-vertical face, and a slightly different mark, was used. The term benchmark, bench mark, or survey benchmark originates from the chiseled horizontal marks that surveyors made in stone structures, into which an angle iron could be placed to form a "bench" for a leveling rod, thus ensuring that a leveling rod could be accurately ...

    The general regression model with n observations and k explanators, the first of which is a constant unit vector whose coefficient is the regression intercept, is = + where y is an n × 1 vector of dependent variable observations, each column of the n × k matrix X is a vector of observations on one of the k explanators, is a k × 1 vector of true coefficients, and e is an n × 1 vector of the ...

    The first, 'arming', loop emits a frequency of 64.25 kHz. The second, 'trigger', loop has a frequency of 65.25 kHz. The other pair of loops is back to back at the signal, and is called a Train Stop System (TSS). The 'arming' and 'trigger' loops work at 66.25 kHz and 65.25 kHz respectively.

    Construction on the Nicholson Cutoff started in May 1912 and the first revenue train to run over the line was on November 6, 1915. While the new 39.6-mile (63.7 km) line resulted in only a modest savings in travel distance (3.6 miles or 5.8 km) the cutoff saved a significant amount of travel time between Scranton, Pennsylvania , and Binghamton ...
