  2. Compound interest - Wikipedia

    en.wikipedia.org/wiki/Compound_interest

    Compound interest is interest accumulated from a principal sum and previously accumulated interest. It is the result of reinvesting or retaining interest that would ...

  3. Numerical solution of the convection–diffusion equation

    en.wikipedia.org/wiki/Numerical_solution_of_the...

    This article describes how to use a computer to calculate an approximate numerical solution of the discretized equation, in a time-dependent situation. In order to be concrete, this article focuses on heat flow, an important example where the convection–diffusion equation applies. However, the same mathematical analysis works equally well to ...

    en.wikipedia.org/wiki/Terahertz_time-domain...

    Typical pulse as measured with THz-TDS. In physics, terahertz time-domain spectroscopy (THz-TDS) is a spectroscopic technique in which the properties of matter are probed with short pulses of terahertz radiation. The generation and detection scheme is sensitive to the sample's effect on both the amplitude and the phase of the terahertz radiation.

  7. Day count convention - Wikipedia

    en.wikipedia.org/wiki/Day_count_convention

    Interest Amount of interest accrued on an investment. CouponFactor The Factor to be used when determining the amount of interest paid by the issuer on coupon payment dates. The periods may be regular or irregular. CouponRate The interest rate on the security or loan-type agreement, e.g., 5.25%. In the formulas this would be expressed as 0.0525.

  8. Alkalinity - Wikipedia

    en.wikipedia.org/wiki/Alkalinity

    Alkalinity can be measured by titrating a sample with a strong acid until all the buffering capacity of the aforementioned ions above the pH of bicarbonate or carbonate is consumed. This point is functionally set to pH 4.5. At this point, all the bases of interest have been protonated to the zero level species, hence they no longer cause ...

  9. Black–Derman–Toy model - Wikipedia

    en.wikipedia.org/wiki/Black–Derman–Toy_model

    Using the calibrated lattice one can then value a variety of more complex interest-rate sensitive securities and interest rate derivatives. Although initially developed for a lattice-based environment, the model has been shown to imply the following continuous stochastic differential equation : [ 1 ] [ 5 ]
