Deepsea Challenge
''Deepsea Challenger'' (DCV 1) is a deep-diving submersible designed to reach the bottom of Challenger Deep, the deepest-known point on Earth. On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second crewed dive reaching the Challenger Deep. Built in Sydney, Australia, by the research and design company Acheron Project Pty Ltd, ''Deepsea Challenger'' includes scientific sampling equipment and high-definition 3-D cameras; it reached the ocean's deepest point after two hours and 36 minutes of descent from the surface. Development ''Deepsea Challenger'' was built in Australia, in partnership with the National Geographic Society and with support from Rolex, in the Deepsea Challenge program. The construction of the submersible was headed by Australian engineer Ron Allum. Many of the submersible developer team members hail from Sydney's cave-diving fraternity including Allum himself with many years' cave-diving experience. ...

Titanic
RMS ''Titanic'' was a British passenger liner, operated by the White Star Line, which sank in the North Atlantic Ocean on 15 April 1912 after striking an iceberg during her maiden voyage from Southampton, England, to New York City, United States. Of the estimated 2,224 passengers and crew aboard, more than 1,500 died, making it the deadliest sinking of a single ship up to that time. It remains the deadliest peacetime sinking of a superliner or cruise ship. The disaster drew public attention, provided foundational material for the disaster film genre, and has inspired many artistic works. RMS ''Titanic'' was the largest ship afloat at the time she entered service and the second of three s operated by the White Star Line. She was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, the chief naval architect of the shipyard, died in the disaster. ''Titanic'' was under the command of Captain Edward Smith, who went down with the ship. The ocean liner carrie ...

Life Support System
A life-support system is the combination of equipment that allows survival in an environment or situation that would not support that life in its absence. It is generally applied to systems supporting human life in situations where the outside environment is hostile, such as outer space or underwater, or medical situations where the health of the person is compromised to the extent that the risk of death would be high without the function of the equipment. In human spaceflight, a life-support system is a group of devices that allow a human being to survive in outer space. US government space agency NASA, and private spaceflight companies use the term environmental control and life-support system or the acronym ECLSS when describing these systems. The life-support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanic Corrosion
Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte. A similar galvanic reaction is exploited in primary cells to generate a useful electrical voltage to power portable devices. This phenomenon is named after Italian physician Luigi Galvani (1737-1798). Overview Dissimilar metals and alloys have different electrode potentials, and when two or more come into contact in an electrolyte, one metal (that's more reactive) acts as anode and the other (that's less reactive) as cathode. The electropotential difference between the reactions at the two electrodes is the driving force for an accelerated attack on the anode metal, which dissolves into the electrolyte. This leads to the metal at the anode corroding more quickly than it otherwise would and corrosion at the cathode being inhibited. The presenc ...

Underwater Acoustic Communication
Underwater acoustic communication is a technique of sending and receiving messages below water. There are several ways of employing such communication but the most common is by using hydrophones. Underwater communication is difficult due to factors such as multi-path radio propagation, propagation, time variations of the channel, small available bandwidth and strong attenuation, signal attenuation, especially over long ranges. Compared to terrestrial communication, underwater communication has low data rates because it uses acoustic waves instead of electromagnetic waves. At the beginning of the 20th century some ships communicated by underwater bells as well as using the system for navigation. Submarine signals were at the time competitive with the primitive maritime radionavigation. The later Fessenden oscillator allowed communication with submarines. Types of modulation used for underwater acoustic communications In general the modulation methods developed for radio communic ...
