  2. Fisher equation - Wikipedia

    en.wikipedia.org/wiki/Fisher_equation

    The Fisher equation can be used in the analysis of bonds.The real return on a bond is roughly equivalent to the nominal interest rate minus the expected inflation rate. But if actual inflation exceeds expected inflation during the life of the bond, the bondholder's real return will suffer.

  3. Doubling time - Wikipedia

    en.wikipedia.org/wiki/Doubling_time

    For example, with an annual growth rate of 4.8% the doubling time is 14.78 years, and a doubling time of 10 years corresponds to a growth rate between 7% and 7.5% (actually about 7.18%). When applied to the constant growth in consumption of a resource, the total amount consumed in one doubling period equals the total amount consumed in all ...

  4. Real interest rate - Wikipedia

    en.wikipedia.org/wiki/Real_interest_rate

    It can be described more formally by the Fisher equation, which states that the real interest rate is approximately the nominal interest rate minus the inflation rate. If, for example, an investor were able to lock in a 5% interest rate for the coming year and anticipated a 2% rise in prices, they would expect to earn a real interest rate of 3% ...

  5. Hemodynamics - Wikipedia

    en.wikipedia.org/wiki/Hemodynamics

    The heart is the driver of the circulatory system, pumping blood through rhythmic contraction and relaxation. The rate of blood flow out of the heart (often expressed in L/min) is known as the cardiac output (CO). Blood being pumped out of the heart first enters the aorta, the largest artery of the body.

  6. Exponential growth - Wikipedia

    en.wikipedia.org/wiki/Exponential_growth

    Many pairs (b, τ) of a dimensionless non-negative number b and an amount of time τ (a physical quantity which can be expressed as the product of a number of units and a unit of time) represent the same growth rate, with τ proportional to log b. For any fixed b not equal to 1 (e.g. e or 2), the growth rate is given by the non-zero time τ.

  7. Mean corpuscular volume - Wikipedia

    en.wikipedia.org/wiki/Mean_corpuscular_volume

    The mean corpuscular volume, or mean cell volume (MCV), is a measure of the average volume of a red blood corpuscle (or red blood cell). The measure is obtained by multiplying a volume of blood by the proportion of blood that is cellular (the hematocrit), and dividing that product by the number of erythrocytes (red

  8. Geometric mean - Wikipedia

    en.wikipedia.org/wiki/Geometric_mean

    For instance, if sales increases by 80% in one year and the next year by 25%, the end result is the same as that of a constant growth rate of 50%, since the geometric mean of 1.80 and 1.25 is 1.50. In order to determine the average growth rate, it is not necessary to take the product of the measured growth rates at every step.

  9. Black–Scholes model - Wikipedia

    en.wikipedia.org/wiki/Black–Scholes_model

    Denoting by S the FOR/DOM exchange rate (i.e., 1 unit of foreign currency is worth S units of domestic currency) one can observe that paying out 1 unit of the domestic currency if the spot at maturity is above or below the strike is exactly like a cash-or nothing call and put respectively. Similarly, paying out 1 unit of the foreign currency if ...
