In computer science and numerical analysis, unit in the last place or unit of least precision (ulp) is the spacing between two consecutive floating-point numbers, i.e., the value the least significant digit (rightmost digit) represents if it is 1. It is used as a measure of accuracy in numeric calculations. [1]
MLWN – mean low water neaps; MLWS – mean low water springs; mm – millimetre (SI unit) MM – prefix designating a number in millions (thousand-thousand) MMbod – million barrels of oil per day; MMboe – million barrels of oil equivalent; MMboed – million barrels of oil equivalent per day; MMbpd – million barrels per day

Fuel impingement in an engine cylinder modeled with KIVA-3V. KIVA-3V is the most mature version of KIVA still maintained and distributed through LANL; it is an improved version of the earlier Federal Laboratory Consortium Excellence in Technology Transfer Award-winning KIVA3 (1993), extended to model vertical or canted valves in the cylinder ...
Typical airflow in a four-stroke engine: In stroke #1, the pistons suck in (aspirate) air to the combustion chamber through the opened inlet valve.. A naturally aspirated engine, also known as a normally aspirated engine, and abbreviated to N/A or NA, is an internal combustion engine in which air intake depends solely on atmospheric pressure and does not have forced induction through a ...
The language definition was updated twice, to FOCAL-69 and a very slightly modified FOCAL-71. A port to the Intel 8080 was also available. FOCAL is notable as the language in which the original versions of the early video games Hamurabi and Lunar Lander were written. Both were later ported to BASIC, where they became much better known.

Next the computer, relying on other instructions Haise typed into it, would fire four of Aquarius 's attitude jets for 7.5 seconds. This procedure, known as ullage , was intended to jolt the spacecraft slightly forward and force the descent engine fuel to the bottom of its tanks, eliminating bubbles and air pockets.
