    Additionally, some manufacturers further cut LVL into sizes for use as chord-members on I-joists. In 2012, North American LVL manufacturers produced more than 1.2 million cubic metres (43.4 million cubic feet) of LVL in 18 different facilities, and in 2013 the production increased by more than 14%.

  3. Orders of magnitude (length) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(length)

    To help compare different orders of magnitude this section lists lengths between 10 −12 and 1011 m (1 pm and 10 pm). 1 pm – distance between atomic nuclei in a white dwarf [citation needed] 1 pm – reference value of particle displacement in acoustics [63] 2.4 pm – the Compton wavelength of an electron; 5 pm – shorter X-ray ...

  4. Feature levels in Direct3D - Wikipedia

    en.wikipedia.org/wiki/Feature_levels_in_Direct3D

    In Direct3D 11, the concept of feature levels has been further expanded to run on most downlevel hardware including Direct3D 9 cards with WDDM drivers.. There are seven feature levels provided by D3D_FEATURE_LEVEL structure; levels 9_1, 9_2 and 9_3 (collectively known as Direct3D 10 Level 9) re-encapsulate various features of popular Direct3D 9 cards conforming to Shader Model 2.0, while ...

  5. Harshad number - Wikipedia

    en.wikipedia.org/wiki/Harshad_number

    The number 18 is a harshad number in base 10, because the sum of the digits 1 and 8 is 9, and 18 is divisible by 9.; The Hardy–Ramanujan number (1729) is a harshad number in base 10, since it is divisible by 19, the sum of its digits (1729 = 19 × 91).

  6. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    In mathematics, a power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power ) of ten.

  7. Educational stage - Wikipedia

    en.wikipedia.org/wiki/Educational_stage

    Dismantling the age-old 10+2 concept, the policy pitches for a "5+3+3+4" design corresponding to the age groups 3–8 years (foundational stage), 811 (preparatory), 11–14 (middle), and 14–18 (secondary). This brings early childhood education (also known as pre-school education for children of ages 3 to 5) under the umbrella of formal ...

  8. Logic level - Wikipedia

    en.wikipedia.org/wiki/Logic_level

    The RS-232 electric signaling uses active low (negative logic). The digital data representing "K" (0x4b) as 7-bit ASCII is framed as "7E1" with 1 start bit, 7 data bits, even parity, 1 stop bit. The use of either the higher or the lower voltage level to represent either logic state is arbitrary.

    en.wikipedia.org/wiki/Evaluation_measures...

    Indexing and classification methods to assist with information retrieval have a long history dating back to the earliest libraries and collections however systematic evaluation of their effectiveness began in earnest in the 1950s with the rapid expansion in research production across military, government and education and the introduction of computerised catalogues.
