The Thunder River Rapids Ride was a river rapid water ride located in the Town of Gold Rush section of Dreamworld on the Gold Coast, Australia.
 It was recently Australia's only river rapids ride; however, a previous Rapids ride, The Snowy River Rampage operated at Wonderland Sydney.
Rumba Rapids is a rapids ride at Thorpe Park, Chertsey, Surrey.
 It opened in 1987 under the name of Thunder River, and is the oldest ride currently still in service at Thorpe Park.
 In 2002, it was refurbished and along with other improvements, its name was changed to Ribena Rumba Rapids because of its sponsor, Ribena.
 In 2006 Ribena's sponsorship contract ended and the ride was named simply Rumba Rapids for the 2007 season.
 Since the refurbishment in 2002 the ride has become significantly slower.
The Dell Rapids Water Tower is a stone water tower located at 10th and Orleans Streets in Dell Rapids, South Dakota.
 The tower was built in 1894 to provide Dell Rapids with a civic water supply.
 The city decided to build the tower after an 1888 fire burned the south side of Main Street.
 The 45 ft water tower is built with Sioux quartzite, a type of red-pink rock found in southern South Dakota, southwest Minnesota, and northwest Iowa.
 The tower provided water to Dell Rapids until 1960, when the city constructed a new tower.
 It is the only stone water tower remaining in South Dakota.
Shoot the Rapids was a log flume water ride located at Cedar Point in Sandusky, Ohio.
 The ride was built and designed by IntaRide (a subsidiary of Intamin) and opened to the public on June 26, 2010.
 Based on a western theme, Shoot the Rapids featured two drops with the second one crossing under the first.
 In February 2016, reports surfaced that the ride would be permanently dismantled.
 On February 20, 2016, Cedar Point officially announced the ride's permanent closure.
Rocky's Rapids is a Log Flume ride at Indiana Beach, in Monticello, Indiana.
 The ride is located next to the Cornball Express, and boats occasionally duel with trains from the roller coaster.
 The park does not have a Rapids ride, so this is one of the park's only water rides.
 The ride is located near Cornball Express and is also not far from Indiana Beach's two othe coasters, Hoosier Hurricane and the steel coaster, Steel Hawg.
A leapfrog filter is a type of active circuit electronic filter that simulates a passive electronic ladder filter.
 Other names for this type of filter are active-ladder or multiple feedback filter.
 The arrangement of feedback loops in the signal flow-graph of the simulated ladder filter inspired the name "leapfrog filter".
 The leapfrog filter maintains the low component sensitivity of the passive ladder filter that it simulates.
A river rapids ride (or river rafting ride) is an amusement ride that simulates whitewater rafting.
The Ayla-Axum amphorae are narrow conical amphoras that were named after the widest range of finds in the Red Sea.
 Subsequent findings since the mid- 1990s indicate, however, that the amphoras originate in Byzantine, or even early Islamic, Aqaba.
 Hence, the preferred nomenclature is now "Aqaba Amphora."
 The Ayla-Axum/Aqaba amphora type has parallels from at least three terrestrial sites in Eritrea and Ethiopia: Aksum, where amphora sherds with gray fabric were found by the Deutsche Aksum Expedition (Zahn 1913: 208); Matara dating to the 4th through 7th centuries (Anfray 1990: 118); and Adulis (Paribeni 1907: 551) examples of which are on display in the National Museum in Asmara.
 Other examples have been found at Berenike in Egypt, where the amphoras date firmly to an early 5th century context in what may be the best stratified examples (Hayes 1996: 159-61); from Aqaba in Jordan where many examples have been found, including their kilns; on The Shipwreck at Black Assarca Island, Eritrea (Pedersen 2008; Pedersen 2000); and in the Mediterranean such as on the late 6th-century shipwreck at Iskandil Burnu, Turkey, as well as in Spain and Carthage in strata datable from the mid-fourth to the sixth centuries (Keay 1986: 356, 358, 471).
 The largest number (c. 500) came to light during excavations at Zafar/Yemen.
Radeau "Land Tortoise" (Shipwreck) is the Lake George site of a shipwreck from the French and Indian Wars era.
 The vessel is a radeau.
 Simple in construction, it was built by Capt. Samuel Cobb of Falmouth, now Portland, Province of Maine for the British and Colonial forces in 1758 to help combat the French in North America.
 She was built in just over a month, launched, tested ("rowed well with 26 oars") and then two days later intentionally sunk by adding ballast with plans to re-float her in the spring of 1759.
 This plan was never fulfilled, however, leaving the Land Tortoise at the bottom of Lake George for more than two centuries.
 It is believed to be the oldest intact warship in North America, and is the only surviving ship of its type.
 It was declared a National Historic Landmark in 1998.
 The site is accessible to the general diving public.
Shipwreck Rapids is a River rapids ride currently operating at SeaWorld San Diego in San Diego, California.
 This attraction is located in the "Shipwreck Island" themed area of the park, themed to a South Pacific island where many ships and their crews have been marooned.
 The four stranded ships are the Implausible, RMS Royal Star, Wholly Mackerel, and Dream Boat II.
