  2. Lookup table - Wikipedia

    en.wikipedia.org/wiki/Lookup_table

    LUTs differ from hash tables in a way that, to retrieve a value with key , a hash table would store the value in the slot () where is a hash function i.e. is used to compute the slot, while in the case of LUT, the value is stored in slot , thus directly addressable.

  3. ISO week date - Wikipedia

    en.wikipedia.org/wiki/ISO_week_date

    When using serial numbers for dates (e.g. in spreadsheets), doy is the serial number for a date minus the serial number for 31st December of the previous year, or alternatively minus the serial number for 1st January the same year plus one. Algorithm. Subtract the weekday number from the ordinal day of the year. Add 10. Divide by 7, discard the ...

    A value can be entered from the computer keyboard by directly typing into the cell itself. Alternatively, a value can be based on a formula (see below), which might perform a calculation, display the current date or time, or retrieve external data such as a stock quote or a database value. The Spreadsheet Value Rule

  5. Six Sigma - Wikipedia

    en.wikipedia.org/wiki/Six_Sigma

    The 3.4 dpmo is based on a "shift" of ± 1.5 sigma explained by Mikel Harry. This figure is based on the tolerance in the height of a stack of discs. [9] [10] Specifically, say that there are six standard deviations—represented by the Greek letter σ —between the mean—represented by μ —and the nearest specification limit. As process ...

  6. Dual dating - Wikipedia

    en.wikipedia.org/wiki/Dual_dating

    Dating based on the year beginning on 25 March became known as "Annunciation Style" dates, while dates of the year commencing on 1 January were described as "Circumcision Style" dates, [2] because this was the date of the Feast of the Circumcision, commemorating the eighth day of Jesus Christ's life after his birth, counted from its observation ...

  7. WI-38 - Wikipedia

    en.wikipedia.org/wiki/WI-38

    The WI-38 cell line stemmed from earlier work by Hayflick growing human cell cultures. [2]In the early 1960s, Hayflick and his colleague Paul Moorhead at the Wistar Institute in Philadelphia, Pennsylvania discovered that when normal human cells were stored in a freezer, the cells remembered the doubling level at which they were stored and, when reconstituted, began to divide from that level to ...

  8. Line–line intersection - Wikipedia

    en.wikipedia.org/wiki/Lineline_intersection

    Assume that we want to find intersection of two infinite lines in 2-dimensional space, defined as a 1 x + b 1 y + c 1 = 0 and a 2 x + b 2 y + c 2 = 0. We can represent these two lines in line coordinates as U 1 = (a 1, b 1, c 1) and U 2 = (a 2, b 2, c 2). The intersection P′ of two lines is then simply given by [4]

  9. Relative dating - Wikipedia

    en.wikipedia.org/wiki/Relative_dating

    Craters are very useful in relative dating; as a general rule, the younger a planetary surface is, the fewer craters it has. If long-term cratering rates are known to enough precision, crude absolute dates can be applied based on craters alone; however, cratering rates outside the Earth-Moon system are poorly known. [8]
