The National Underwater and Marine Agency (NUMA) is a private non-profit organization in the United States founded in 1979. Originally it was a fictional US government organization in the novels of author Clive Cussler .
The Experimental Test Pool is a 50,000-US-gallon (190,000 L) capacity freshwater tank measuring 15 ft (4.6 m) by 30 ft (9.1 m) by 15 ft (4.6 m) deep, capable of sustaining temperatures from 34 to 105 °F (1 to 41 °C). It is designed and constructed for manned, shallow water testing and for supporting workup dives for the Ocean Simulation Facility.
Turtle was designed to dive to 6500 feet. When DSV-2 Alvin installed a new titanium hull, the Alvin steel hull was installed in the Turtle. The original steel hull was acquired by the Mariners' Museum and Park in 2000 and became a part of the exhibition. [2] The Turtle depth rating was then increased to 10,000 feet.
23 January 1960: the Bathyscaphe Trieste just before the record dive. Behind her is the USS Lewis Don Walsh and Jacques Piccard inside the Bathyscaphe Trieste. Project Nekton was the codename for a series of very shallow test dives (three of them in Apra Harbor) and also deep-submergence operations in the Pacific Ocean near Guam that ended with the United States Navy-owned research bathyscaphe ...
The Flyaway Deep Ocean Salvage System (FADOSS) is a modular system used by the United States Navy to raise sunken objects, such as aircraft or small vessels. It has a maximum lifting capacity of 60,000 lb (27,000 kg), and can recover objects from depths of 20,000 ft (6,100 m).
In all cases the computer monitors the depth and elapsed time of the dive, and many allow user input specifying the gas mixture. [32] Most computers require the diver to specify the mixture before the dive, but some allow the choice of mixture to be changed during the dive, which allows for the use of gas switching for accelerated decompression.
The use of non-uniform memory access (NUMA) allowed a processor to access its own local memory faster than other memory locations, while cache-only memory architectures (COMA) allowed for the local memory of each processor to be used as cache, thus requiring coordination as memory values changed.
Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to the processor. Under NUMA, a processor can access its own local memory faster than non-local memory (memory local to another processor or memory shared between processors). [ 1 ]
