Line regulation. Line regulation is the ability of a power supply to maintain a constant output voltage despite changes to the input voltage, with the output current drawn from the power supply remaining constant. where ΔVi is the change in input voltage while ΔVo is the corresponding change in output voltage.
An example of experience curve effects: Swanson's law states that solar module prices have dropped about 20% for each doubling of installed capacity. In industry, models of the learning or experience curve effect express the relationship between experience producing a good and the efficiency of that production, specifically, efficiency gains that follow investment in the effort.
"The curve" is the permitted range of each letter grade that can be awarded, for example, 0–3% A+, 3–7% A, etc. Curves vary between different law schools, as do the rules for when the curve is mandatory versus suggestive. It is common for the curve to be mandatory for first-year ("1L") courses, and for classes above a certain size.
Oil depletion. Oil depletion is the decline in oil production of a well, oil field, or geographic area. [1] The Hubbert peak theory makes predictions of production rates based on prior discovery rates and anticipated production rates. Hubbert curves predict that the production curves of non-renewing resources approximate a bell curve.
Imagine that there are three tax brackets: 10%, 20%, and 30%. The 10% rate applies to income from $1 to $10,000; the 20% rate applies to income from $10,001 to $20,000; and the 30% rate applies to all income above $20,000. Under this system, someone earning $10,000 is taxed at 10%, paying a total of $1,000. Someone earning $5,000 pays $500, and ...
A truncated mean or trimmed mean is a statistical measure of central tendency, much like the mean and median. It involves the calculation of the mean after discarding given parts of a probability distribution or sample at the high and low end, and typically discarding an equal amount of both. This number of points to be discarded is usually ...
The mileage for dual-fuel vehicles, such as E85 capable models and plug-in hybrid electric vehicles, is computed as the average of its alternative fuel rating—divided by 0.15 (equal to multiplying by 6.666)—and its gasoline rating. Thus an E85-capable vehicle that gets 15 mpg on E-85 and 25 mpg on gasoline might logically be rated at 20 mpg.
The fixed rate for a 15-year mortgage is 6.17%, down 12 basis points from last week's average 6.29%. These figures are higher than a year ago, when rates averaged 6.69% for a 30-year term and 6.10 ...
