By construction, hypothesis testing limits the rate

By 2000, most large-scale ( Mach-like ) efforts had ended, although OpenStep used an adapted Mach kernel called XNU, which is now used in the OS known as Darwin, which is the open source part of Mac OS X .. As of 2012, the Mach-based GNU Hurd is also functional and its inclusion in testing versions of Arch Linux and Debian in progress.

By 1987 the list included the Encore Multimax and Sequent Balance machines, testing Mach's ability to run on multiprocessor systems.

By 1961, several test articles were ready for testing from USAF B-52 bombers, with drop-tests starting in January.

By the spring of 1956 they had a near-final design, which was awarded a preproduction contract for 1, 000 M18A1 claymores designated T-48E1 during testing.

By the end of World War Two, the US had built eight new wind tunnels, including the largest one in the world at Moffett Field near Sunnyvale, California, which was designed to test full size aircraft at speeds of less than 250 mph and a vertical wind tunnel at Wright Field, Ohio, where the wind stream is upwards for the testing of models in spin situations and the concepts and engineering designs for the first primitive helicopters flown in the US.

By the end of 2012 cargo supply to the International Space Station will be flown by privately owned commercial craft under NASA's Commercial Resupply Services by SpaceX's successfully tested the partially reusable Dragon spacecraft, and Orbital Sciences ' Cygnus spacecraft ( also slated for testing in 2012 ).

By focussing on just a few of these highly variable minisatellites, DNA profiling made the system more sensitive, more reproducible, and amenable to computer databasing, and soon became the standard forensic DNA system used in criminal case work and paternity testing worldwide.

By testing the samples from the spring water, the team was at least able to identify the substance's current presence at the site, giving them insight that a presumably larger quantity existed in the waters thousands of years earlier.

By testing various hypotheses, these researchers hope to discover the unique mechanism that causes the spontaneous pain of CRPS and that discovery may lead to new ways of blocking pain.

By May 1998 Acorn started to offer their ' Registered Developer ' scheme members the chance to pre-order a pre-launch prototype for testing and development, these were offered at a £ 950 ( ex VAT ) a significant discount on the public price of £ 1500 ( ex VAT ) revealed in June ..

By the time the prototype was ready for testing, it weighed over 12, 550 lb., over the Army's limit for the new fighter design, and far more than any single-engine fighter ever developed.
