2matching — The process of making a study group and a comparison group in an epidemiological study comparable with respect to extraneous or confounding factors such as age, sex, weight. impedance m. the force delivered through the mechanical advantag …
3Matching — F/A/V Arranging for the impedances presented by a load to be equal to the internal impedance of the generator. This is essential to avoid loss of power. In microphones, the loss results in poorer signal to noise ratio. Matching is done by means… …
4Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
5Standing wave ratio — In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. The SWR is usually defined as a …
6Financial ratio — Corporate finance …
7Ventilation/perfusion ratio — In respiratory physiology, the ventilation/perfusion ratio (or V/Q ratio) is a measurement used to assess the efficiency and adequacy of the matching of two variables: [LoyolaMedEd|Medicine/pulmonar/physio/pf9.htm#q1] * V ventilation the air… …
8hedge ratio — The relationship between the number of contracts required for a direct hedge and the number of contracts required to hedge in a specific situation. The concept of hedging is to match the size of a positive cash flow from a gaining futures… …
9Prediction by Partial Matching — (PPM) is an adaptive statistical data compression technique based on context modeling and prediction. PPM models use a set of previous symbols in the uncompressed symbol stream to predict the next symbol in the stream.Predictions are usually… …
10Extended matching items — Extended matching items/questions (EMI or EMQ) are a written examination format similar multiple choice questions but with one key difference, that they test knowledge in a far more applied, in depth, sense.It is often used in medical education… …
