  2. General radiotelephone operator license - Wikipedia

    en.wikipedia.org/wiki/General_radiotelephone...

    To test for the First Class license one had to have passed the exam for a Second Class license. Because it included the entire field of electronics transmission, the examination to earn the Second was generally thought of as more difficult than that of the First, which concentrated on broadcast radio and television.

  3. Color rendering index - Wikipedia

    en.wikipedia.org/wiki/Color_rendering_index

    If the test source has a CCT < 5000 K, use a black body for reference, otherwise use CIE standard illuminant D. Both sources should have the same CCT. Both sources should have the same CCT. Ensure that the chromaticity distance (DC) of the test source to the Planckian locus is under 5.4×10 −3 in the CIE 1960 UCS.

  4. Closed-circuit television - Wikipedia

    A more open question is whether most CCTV is cost-effective. While low-quality domestic kits are cheap, the professional installation and maintenance of high definition CCTV is expensive. [ 43 ] Gill and Spriggs did a cost-effectiveness analysis (CEA) of CCTV in crime prevention that showed little monetary saving with the installation of CCTV ...

  5. Closed-circuit television camera - Wikipedia

    en.wikipedia.org/wiki/Closed-circuit_television...

    These cameras do not require a video capture card because they work using a digital signal which can be saved directly to a computer. The signal is compressed 5:1, but DVD quality can be achieved with more compression (MPEG-2 is standard for DVD-video, and has a higher compression ratio than 5:1, with a slightly lower video quality than 5:1 at best, and is adjustable for the amount of space to ...

  6. Correlated color temperature - Wikipedia

    en.wikipedia.org/wiki/Correlated_color_temperature

    The CIE recommends that "The concept of correlated color temperature should not be used if the chromaticity of the test source differs more than Δ uv = 5×10 −2 from the Planckian radiator." [22] Beyond a certain value of Δ uv, a chromaticity co-ordinate may be equidistant to two points on the locus, causing ambiguity in the CCT.

  7. Multiple choice - Wikipedia

    en.wikipedia.org/wiki/Multiple_choice

    A multiple choice question, with days of the week as potential answers. Multiple choice (MC), [1] objective response or MCQ(for multiple choice question) is a form of an objective assessment in which respondents are asked to select only the correct answer from the choices offered as a list.

  8. Conditional cash transfer - Wikipedia

    en.wikipedia.org/wiki/Conditional_cash_transfer

    Few development initiatives have been evaluated as rigorously as CCT programs. [1] The implementation of conditional cash transfer programs has been accompanied by systematic efforts to measure their effectiveness and understand their broader impact on household behavior, [1] a marked departure from the limited attention that was paid to rigorous impact evaluations in the past.

  9. Computerized classification test - Wikipedia

    en.wikipedia.org/wiki/Computerized...

    A computerized classification test (CCT) refers to a Performance Appraisal System that is administered by computer for the purpose of classifying examinees. The most common CCT is a mastery test where the test classifies examinees as "Pass" or "Fail," but the term also includes tests that classify examinees into more than two categories.
