Absolute cylinder pressure is used to calculate the dynamic compression ratio, using the following formula: = where is a polytropic value for the ratio of specific heats for the combustion gases at the temperatures present (this compensates for the temperature rise caused by compression, as well as heat lost to the cylinder)
Solution of a travelling salesperson problem: the black line shows the shortest possible loop that connects every red dot. The travelling salesman problem, also known as the travelling salesperson problem (TSP), asks the following question: "Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns ...
The point D is the harmonic conjugate of C with respect to A and B precisely if the cross-ratio of the quadruple is −1, called the harmonic ratio. The cross-ratio can therefore be regarded as measuring the quadruple's deviation from this ratio; hence the name anharmonic ratio. The cross-ratio is preserved by linear fractional transformations.
In this case, the branching ratio is just the ratio of the branching fractions between two states. To use our example from before, if the branching fraction to state |g is p {\displaystyle p} , then the branching ratio comparing the transition rates to |g and |d would be p 1 − p {\displaystyle {\frac {p}{1-p}}} .
Contribution margin-based pricing is a pricing strategy which works without any mention of gross margin percentages. (German:Deckungsbeitrag) It maximizes the profit derived from a company's assortment, based on the difference between a product's price and variable costs (the product's contribution margin per unit), and on one's assumptions regarding the relationship between the product's ...
In the United Kingdom and Hong Kong both plot ratio and site ratio are used. [7] [8] In Singapore the terms plot ratio and gross plot ratio (GPR) are more commonly used. In the United States and Canada, floor space ratio (FSR) and floor area ratio (FAR) are both used. [9] Use ratios are used as a measure of the density of the site being developed.
Even though this term would seem to be a straightforward ratio, when price performance is improved, better, or increased, it actually refers to the performance divided by the price, in other words exactly the opposite ratio (i.e. an inverse ratio) to rank a product as having an increased price/performance.
The price/cash flow ratio (also called price-to-cash flow ratio or P/CF), is a ratio used to compare a company's market value to its cash flow.It is calculated by dividing the company's market cap by the company's operating cash flow in the most recent fiscal year (or the most recent four fiscal quarters); or, equivalently, divide the per-share stock price by the per-share operating cash flow.
