  2. Glomerular filtration rate - Wikipedia

    en.wikipedia.org/wiki/Glomerular_filtration_rate

    The filtration fraction is the amount of plasma that is actually filtered through the kidney. This can be defined using the equation: FF= ⁠ GFR / RPF ⁠ FF is the filtration fraction; GFR is the glomerular filtration rate; RPF is the renal plasma flow; Normal human FF is 20%.

  3. Image sensor format - Wikipedia

    en.wikipedia.org/wiki/Image_sensor_format

    Sizes are often expressed as a fraction of an inch, with a one in the numerator, and a decimal number in the denominator. For example, 1/2.5 converts to 2/5 as a simple fraction, or 0.4 as a decimal number. This "inch" system gives a result approximately 1.5 times the length of the diagonal of the sensor.

  4. Hexadecimal - Wikipedia

    en.wikipedia.org/wiki/Hexadecimal

    Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.

  5. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Water can generate electricity with a conversion efficiency of about 90%, which is the highest rate in renewable energy. [88] There are many forms of water energy: Historically, hydroelectric power came from constructing large hydroelectric dams and reservoirs, which are still popular in developing countries. [89]

  6. Homomorphic encryption - Wikipedia

    en.wikipedia.org/wiki/Homomorphic_encryption

    Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without first having to decrypt it. The resulting computations are left in an encrypted form which, when decrypted, result in an output that is identical to that of the operations performed on the unencrypted data.

  7. Light-emitting diode - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode

    A fraction of the blue light undergoes the Stokes shift, which transforms it from shorter wavelengths to longer. Depending on the original LED's color, various color phosphors are used. Using several phosphor layers of distinct colors broadens the emitted spectrum, effectively raising the color rendering index (CRI).

    The module is then crushed in a mill and the different fractions are separated – glass, plastics and metals. [76] It is possible to recover more than 80% of the incoming weight. [ 77 ] This process can be performed by flat glass recyclers, since the shape and composition of a PV module is similar to flat glass used in the building and ...
