  2. Baldwin DR-12-8-1500/2 - Wikipedia

    en.wikipedia.org/wiki/Baldwin_DR-12-8-1500/2

    The Baldwin DR-12-8-1500/2 (known informally as the Centipede) was the Baldwin Locomotive Works' first serious attempt at a production road diesel locomotive. The Baldwin type designation was ' DR-12-8-1500/2 , ' meaning D iesel R oad locomotive, with 12 axles ( 8 of which were driven), and two engines of 1,500 horsepower (1,100 kW) each.

  3. Accurizing - Wikipedia

    en.wikipedia.org/wiki/Accurizing

    Comparison of milliradian (mil) and minute of arc (moa).. Since adjusting the point of impact to match the point of aim is relatively simple with any type of adjustable sights, the primary goal of accurizing is to increase the precision of the firearm, which is generally measured by looking at the dispersion of a number of shots fired at the same point of aim.

  4. Class of accuracy in electrical measurements - Wikipedia

    en.wikipedia.org/wiki/Class_of_accuracy_in...

    In electrical engineering, characteristics like current or voltage can be measured by an ammeter, a voltmeter, a multimeter, etc.The ammeter is used in series with the load, so the same current flows through the load and the ammeter.

  5. Accuracy and precision - Wikipedia

    en.wikipedia.org/wiki/Accuracy_and_precision

    Accuracy is also used as a statistical measure of how well a binary classification test correctly identifies or excludes a condition. That is, the accuracy is the proportion of correct predictions (both true positives and true negatives) among the total number of cases examined. [10]

  6. Precision tests of QED - Wikipedia

    en.wikipedia.org/wiki/Precision_tests_of_QED

    The current state-of-the-art theoretical calculation of the anomalous magnetic dipole moment of the electron includes QED diagrams with up to four loops. Combining this with the experimental measurement of g yields the most precise value of α: [4] α −1 = 137.035 999 166 (15), a precision of better than a part in a billion.

  7. Resistor ladder - Wikipedia

    en.wikipedia.org/wiki/Resistor_ladder

    The required accuracy doubles with each additional bit: for 8 bits, the accuracy required will be better than 1 ⁄ 256 (~0.4%). [ clarification needed ] However, variances for resistances when manufactured in a single component tend to be much lower than variances between components or between batches of manufacturing, and hence a resistor ...

  8. Evaluation of binary classifiers - Wikipedia

    en.wikipedia.org/wiki/Evaluation_of_binary...

    The basic marginal ratio statistics are obtained by dividing the 2×2=4 values in the table by the marginal totals (either rows or columns), yielding 2 auxiliary 2×2 tables, for a total of 8 ratios. These ratios come in 4 complementary pairs, each pair summing to 1, and so each of these derived 2×2 tables can be summarized as a pair of 2 ...

    It carried 15 rounds for the main gun. The hulls were left over from Henschel's submission for the canceled VK 30.01 heavy tank program - development of a 30-tonne tank which led to the Tiger - but the hull was stretched and an extra road wheel added to its overlapped and interleaved Schachtellaufwerk roadwheel-based suspension system, to ...
