Military Diving
Underwater divers may be employed in any branch of an armed force, including the navy, army, marines, air force and coast guard. Scope of operations includes: search and recovery, search and rescue, hydrographic survey, explosive ordnance disposal, demolition , underwater engineering, salvage, ships husbandry, reconnaissance, infiltration, sabotage, counterifiltration, underwater combat and security. History of military diving Military divers are essential to many missions and campaigns. Combat and demolition work, underwater and coastal reconnaissance, ordnance disposal, search and rescue, salvage operations, construction, ship maintenance and underwater engineering. Every branch of the U.S. military employs divers, and more than 40 nations have military diving units. Military diving is an occupation that has risks and responsibilities beyond those of other professional diving.

Siebe Gorman CDBA
The Clearance Divers Breathing Apparatus (CDBA) is a type of rebreather made by Siebe Gorman in England. The British Royal Navy used it for many years. It was for underwater work rather than for combat diving. The main oxygen cylinders are on the diver's back. The oxygen cylinders at the front of the diver are for bailout. In its basic mode it was an oxygen rebreather; but some of the cylinders could be replaced by diluent cylinders for nitrox mode (which the Navy called "mixture"), and then the set was sometimes called CDMBA. The Royal Navy was using nitrox from 1944, but did not reveal its nitrox techniques, and in the 1960s and afterwards civilian divers had to retread the same ground and develop nitrox diving independently. In later years it was called DSSCCD from "Diving Set, Self-Contained, Clearance Diver". Design The CDBA was very popular with the clearance divers. It is comfortable since there is no cylinder on the middle of the back, no bulky buoyancy compensator, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carleton CDBA
Cobham Limited is a British aerospace manufacturing company based in Bournemouth, England. Cobham was originally founded by Sir Alan Cobham as Flight Refuelling Limited (FRL) in 1934. During 1939, British airline Imperial Airways performed several non-stop crossings of the Atlantic using equipment provided by FRL. During the late 1940s, the company's aerial refuelling equipment broke new ground, including a round-the-world flight by specially-equipped Boeing B-50 Superfortresses in 1948 and the demonstration of the now-widely used Aerial refueling#Probe-and-drogue, 'probe and drogue' method of air-to-air refuelling for the first time in 1949. A wide range of aircraft have since been equipped with Cobham's refuelling equipment. The company has grown and diversified into various markets, often through acquisitions. Michael Cobham, Alan's son, took over its leadership during 1969. During 1994, the firm was formally renamed Cobham plc; by this point, the company had in excess of 1 ...

Computer
A computer is a machine that can be programmed to Execution (computing), carry out sequences of arithmetic or logical operations (computation) automatically. Modern digital electronic computers can perform generic sets of operations known as Computer program, programs. These programs enable computers to perform a wide range of tasks. A computer system is a nominally complete computer that includes the Computer hardware, hardware, operating system (main software), and peripheral equipment needed and used for full operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of Programmable logic controller, industrial and Consumer electronics, consumer products use computers as control systems. Simple special-purpose devices like microwave ovens and remote controls are included, as are factory devices like industrial robots and computer-aided design, as well as general-purpose devi ...

Current Differencing Buffered Amplifier
A current differencing buffered amplifier (CDBA) is a multi-terminal active component with two inputs and two outputs and developed by Cevdet Acar and Serdar Özoğuz. Its block diagram can be seen from the figure. It is derived from the current feedback amplifier (CFA). Basic operation The characteristic equation of this element can be given as: #Vp=Vn=0, #Iz=Ip-In, #Vw=Vz. Here, the current through the z-terminal follows the difference between the currents through p-terminal and n-terminal. Input terminals p and n are internally grounded. The difference of the input currents is converted into the output voltage Vw, therefore CDBA element can be considered as a special type of current feedback amplifier with differential current input and grounded y input. The CDBA is simplifies the implementation, is free from parasitic capacitances, able to operate in the frequency range of more than hundreds of MHz (even GHz!), and suitable for current mode operation while, it also p ...

Electronics
The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow. Electronics has hugely influenced the development of modern society. The central driving force behind the entire electronics industry is the semiconductor industry sector, which has annual sales of over $481 billion as of 2018. The largest industry sector is e-commerce, which generated over $29 trillion in 2017. History and development Electronics has hugely influenced the development of modern society. The identification of the electron in 1897, along with the subsequent invention of the vacuum tube which could amplify and rectify small ele ...

Dragon Boat
A dragon boat is a human-powered watercraft originating from the Pearl River Delta region of China's southern Guangdong Province. These were made of teak, but in other parts of China, different kinds of wood are used. It is one of a family of traditional paddled long boats found throughout Asia, Africa, the Pacific islands, and Puerto Rico. The sport of dragon boat racing has its roots in an ancient folk ritual of contending villagers, which dates back 2000 years throughout southern China, and even further to the original games of Olympia in ancient Greece. Both dragon boat racing and the ancient Olympiad included aspects of religious observances and community celebrations, along with competitions. Dragon boat racing has been a traditional Chinese paddled watercraft activity for over 2000 years and began as a modern international sport in Hong Kong in 1976. These boats are typically made of carbon fiber, fiberglass, and other lightweight materials. For competition event ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canberra Dragon Boat Association
Canberra ( ) is the capital city of Australia. Founded following the federation of the colonies of Australia as the seat of government for the new nation, it is Australia's largest inland city and the eighth-largest city overall. The city is located at the northern end of the Australian Capital Territory at the northern tip of the Australian Alps, the country's highest mountain range. As of June 2021, Canberra's estimated population was 453,558. The area chosen for the capital had been inhabited by Indigenous Australians for up to 21,000 years, with the principal group being the Ngunnawal people. European settlement commenced in the first half of the 19th century, as evidenced by surviving landmarks such as St John's Anglican Church and Blundells Cottage. On 1 January 1901, federation of the colonies of Australia was achieved. Following a long dispute over whether Sydney or Melbourne should be the national capital, a compromise was reached: the new capital would be bu ...
