[9] [failed verification] Each degree was subdivided into 60 minutes and each minute into 60 seconds. [10] [11] Thus, one Babylonian degree was equal to four minutes in modern terminology, one Babylonian minute to four modern seconds, and one Babylonian second to 1 / 15 (approximately 0.067) of a modern second.
Experts historically used a reaction time of 0.75 seconds, but now incorporate perception resulting in an average perception-reaction time of: 1 second for population as an average; occasionally a two-second rule to simulate the elderly or neophyte; [Note 4] or even a 2.5 second reaction time—to specifically accommodate very elderly ...
= 10.5 seconds ; = 7,200 passengers per hour if 4 people per car and 2 seconds headway is assumed, or 342 passengers per hour if 1 person per car and 10,5 seconds headway is assumed. The headway used in reality is much less than 10.5 seconds, since the brick-wall principle is not used on freeways.
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.
A basic installation of IBM 7030 Stretch had a cost at the time of US$7.78 million each. The IBM 7030 Stretch performs one floating-point multiply every 2.4 microseconds. [78] Second-generation (discrete transistor-based) computer. 1964 $2.3B: $23.318B Base model CDC 6600 price: $6,891,300.
Hexadecimal time is the representation of the time of day as a hexadecimal number in the interval [0, 1). The day is divided into 10 16 (16 10 ) hexadecimal hours, each hour into 100 16 (256 10 ) hexadecimal minutes, and each minute into 10 16 (16 10 ) hexadecimal seconds.
Time of useful consciousness (TUC), ... 30 to 60 seconds FL350 (35,000 ft; 10,650 m) 30 to 60 seconds 15 to 30 seconds FL400 (40,000 ft; 12,200 m)
Total Time: 8-hour shift or 28,800 seconds, producing 14,400 parts, or one part every 2 seconds. Fastest possible cycle time is 1.5 seconds, hence only 21,600 seconds would have been needed to produce the 14,400 parts. The remaining 7,200 seconds or 2 hours were lost. The OEE is now the 21,600 seconds divided by 28,800 seconds (same as minimal ...
