    (3) Financial capital maintenance in units of CPP in terms of a Daily Consumer Price Index or daily rate at all levels of inflation and deflation (see the original Framework (1989), Par 104 (a)) [now Conceptual Framework (2010), Par. 4.59 (a)] under the Capital Maintenance in Units of Constant Purchasing Power paradigm.

  3. Algorithms for calculating variance - Wikipedia

    en.wikipedia.org/wiki/Algorithms_for_calculating...

    This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.

    en.wikipedia.org/wiki/Datasheet

    Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...

  5. Equalization payments in Canada - Wikipedia

    en.wikipedia.org/wiki/Equalization_payments_in...

    The equalization formula has been criticized for not factoring in a below market sale of hydro power to domestic users into the calculation of equalization payments. Between 2005 and 2010, Quebec was calculated to have received 51% more equalization ($42.4 B vs $28.1 B) than it would have if the formula was corrected the same for resource ...

    The gradient of a function is obtained by raising the index of the differential , whose components are given by: =; =; =, = = The divergence of a vector field with components is

  7. Coronary perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Coronary_perfusion_pressure

    Because CPP is measured by the difference in aortic and LVEDP pressures, an increase in LVEDP will decrease CPP. The heart may compensate for this reduction in CPP by increasing contractility and subsequent aortic pressure. However, this process requires greater oxygen consumption and will promote ventricular remodeling. While this process may ...

  8. Variable-pitch propeller (marine) - Wikipedia

    en.wikipedia.org/wiki/Variable-pitch_propeller...

    In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution.

  9. Cerebral perfusion pressure - Wikipedia

    en.wikipedia.org/wiki/Cerebral_perfusion_pressure

    An alternative definition of CPP is: [1] = where: MAP is mean arterial pressure ICP is intracranial pressure JVP is jugular venous pressure. This definition may be more appropriate if considering the circulatory system in the brain as a Starling resistor, where an external pressure (in this case, the intracranial pressure) causes decreased blood flow through the vessels.
