In the mid-1960s, to defeat the advantage of the recently introduced computers for the then popular rally racing in the Midwest, competition lag times in a few events were given in centids (1 ⁄ 100 day, 864 seconds, 14.4 minutes), millids (1 ⁄ 1,000 day, 86.4 seconds), and centims (1 ⁄ 100 minute, 0.6 seconds) the latter two looking and ...
[88] [90] [91] The low detection rate may be a result of low sensitivity of current detectors to long-duration events, rather than a reflection of their true frequency. [88] A 2013 study, [ 92 ] on the other hand, shows that the existing evidence for a separate ultra-long GRB population with a new type of progenitor is inconclusive, and further ...
It estimated that repairs would take at least two months, owing to the time needed to warm up the affected sectors and then cool them back down to operating temperature. [87] CERN released an interim technical report [ 86 ] and preliminary analysis of the incident on 15 and 16 October 2008 respectively, [ 88 ] and a more detailed report on 5 ...
However, when it is inconvenient to use base-60 for minutes and seconds, positions are frequently expressed as decimal fractional degrees to an equal amount of precision. Degrees given to three decimal places ( 1 / 1000 of a degree) have about 1 / 4 the precision of degrees-minutes-seconds ( 1 / 3600 of a degree) and ...
A study published in 2009 in the journal Aviation, Space and Environmental Medicine campared ascent rates of 30 feet per minute and 60 feet per minute in recreational divers. The group using the faster ascent rate had higher bubble grades after the dive measured ultrasonically, which supports the hypothesis that slower ascents reduce ...
Approval of CD-1 occurred in December 2012 [39] The approved design significantly scaled back the physicist's request, which cost $1.7B. The CD-1 approval was for a budget of $850M, the proposed near detector was not included and the far detectors were recommended to be located on the surface rather than underground.
This gave greater depth, but was a non-discriminate mode. It worked best at lower frequencies than those used before, and frequencies of 3 to 20 kHz were found to produce the best results. Many detectors in the 1970s had a switch which enabled the user to switch between the discriminate mode and the non-discriminate mode.
Angles in the hours ( h), minutes ( m), and seconds ( s) of time measure must be converted to decimal degrees or radians before calculations are performed. 1 h = 15°; 1 m = 15′; 1 s = 15″ Angles greater than 360° (2 π ) or less than 0° may need to be reduced to the range 0°−360° (0–2 π ) depending upon the particular calculating ...
