The 140-foot (43 m), 500-ton, $27 million fast response boat is the country's largest fireboat, with a maximum speed of 18 knots (33 km/h; 21 mph). The Three Forty Three incorporates the latest technology available for marine vessels, including the capability of pumping 50,000 US gallons (190,000 L; 42,000 imp gal) of water per minute, nearly ...
For much of the late 19th and early 20th century, New York City maintained a fleet of ten fireboats. In recent decades technology has improved to where smaller boats can provide the pumping capacity that required a large boat in the past. [1] These smaller boats require smaller crews, and the crews themselves require less training.
A 10-Mbit/s Ethernet link is often transported over a VC-12-5v which allows the full bandwidth to be carried for all packet sizes. A 100-Mbit/s Ethernet link is often transported over a VC-3-2v which allows the full bandwidth to be carried when smaller packets are used (< 250 bytes) and Ethernet flow control restricts the rate of traffic for ...
Ethernet over PDH over SONET/SDH (EoPoS) is one of many techniques that provided Ethernet connectivity over non-Ethernet networks. EoPoS is a standardized method for transporting native Ethernet frames over the existing telecommunications optical infrastructure use both the established Plesiochronous Digital Hierarchy (PDH) and Synchronous Digital Hierarchy (SONET/SDH) transport technologies.
SONET/SDH is not a complete communications protocol in itself, but a transport protocol (not a "transport" in the OSI Model sense). Due to SONET/SDH's essential protocol neutrality and transport-oriented features, SONET/SDH was the choice for transporting the fixed length Asynchronous Transfer Mode (ATM) frames also known as cells. It quickly ...
In conjunction with LCAS and GFP, Virtual Concatenation gives the advantage of splitting the required bandwidth equally among a set number of sub paths called Virtual Tributaries (VT). The Virtual Concatenation is specified in ITU-T Recommendations G.707 (2007) [ 1 ] and G.783 (2006).
We are just days from the Indianapolis 500 and the starting grid is set. After two days of qualifying, Scott McLaughlin earned the pole position at 234.220 mph for his 4-lap run around the 2.5 ...
For the 1964 New York World's Fair, the latest version of the gas turbine engine, designated GT-309, was fitted to a New Look bus (TDH-5303, serial #0001) and named "Turbo-Cruiser II"; [9] the GT-309 was also fitted to the Chevrolet Tilt-Cab truck chassis and called "Turbo Titan III". The GT-309 developed power and torque comparable to the 8V ...
