"the overall performance improvement gained by optimizing a single part of a system is limited by the fraction of time that the improved part is actually used". [ 2 ] It is named after computer scientist Gene Amdahl , and was presented at the American Federation of Information Processing Societies (AFIPS) Spring Joint Computer Conference in 1967.
68% of the used energy is lost in conversion into d-glucose; 35–45% of the glucose is consumed by the leaf in the processes of dark and photo respiration; Stated another way: 100% sunlight → non-bioavailable photons waste is 47%, leaving; 53% (in the 400–700 nm range) → 30% of photons are lost due to incomplete absorption, leaving
The theoretical molar yield is 2.0 mol (the molar amount of the limiting compound, acetic acid). The molar yield of the product is calculated from its weight (132 g ÷ 88 g/mol = 1.5 mol). The % yield is calculated from the actual molar yield and the theoretical molar yield (1.5 mol ÷ 2.0 mol × 100% = 75%). [citation needed]
The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...
Modified duration is measured as the percent change in price per one unit (percentage point) change in yield per year (for example yield going from 8% per year (y = 0.08) to 9% per year (y = 0.09)). This will give modified duration a numerical value close to the Macaulay duration (and equal when rates are continuously compounded).
To calculate first time yield (FTY) you would: Calculate the yield (number out of step/number into step) of each step. Multiply these together. For example: (# units leaving the process as good parts) / (# units put into the process) = FTY 100 units enter A and 90 leave as good parts. The FTY for process A is 90/100 = 0.9000
The "on time" for a 60% duty cycle could be a fraction of a second, a day, or even a week, depending on the length of the period. Duty cycles can be used to describe the percent time of an active signal in an electrical device such as the power switch in a switching power supply or the firing of action potentials by a living system such as a ...
Yield is usually stated as percentage per fission, so that the total yield percentages sum to 200%. Less often, it is stated as percentage of all fission products, so that the percentages sum to 100%. Ternary fission, about 0.2–0.4% of fissions, also produces a third light nucleus such as helium-4 (90%) or tritium (7%).
