nomogram

 [nom´o-gram]
a graph with several scales arranged so that a straightedge laid on the graph intersects the scales at related values of the variables; the values of any two variables can be used to find the values of the others.

nom·o·gram

(nōm'ō-gram),
1. A form of line chart showing scales for the variables involved in a particular formula such that corresponding values for each variable lie in a straight line intersecting all the scales.
2. A line chart in toxicology that relates time since toxic ingestion with blood levels of the offending agent to estimate levels of toxicity and to guide therapy.
Synonym(s): nomograph (2)
[G. nomos, law, + gramma, something written]

nomogram

An alignment chart in which there are ≥ 3 abscissas, each measuring a specific parameter and mathematically or empirically defined as having a relationship to the other two; the abscissas are placed parallel to each other on an open 2-D field; a straight line drawn when 2 parameters are known allows determination of the value of a 3rd–unknown parameter

nom·o·gram

(nōmō-gram)
A form of line chart showing scales for the variables involved in a particular formula in such a way that corresponding values for each variable lie in a straight line intersecting all the scales.

tonography 

Technique for measuring the facility of outflow of aqueous humour from the eye under the continuous pressure exerted by the weight of a tonometer over a given period of time. The instrument usually employed for tonography is an electronically recording Schiötz tonometer. In this technique, the pressure is continuously recorded over a four-minute period and the outflow is deduced by utilizing a specifically designed diagram, called a nomogram (which is a graphical representation of one, or more, mathematical relationships whereby the desired value may be found without calculation by placing a straight edge across the diagram). The results of tonography can indicate the presence of established glaucoma, although the technique is not very reliable for borderline cases.

Linear chart showing scales for the variables involved in a particular formula such that corresponding values for each variable lie in a straight line intersecting all the scales.

The developed lines (nomograph) explain the sensitivity of S and B for both S [less than] B and S [greater than] B.
Examination of the nomograph in Table II supports several ideas about the FSA designated amount.
At t = .1, the nomograph in Table II illustrates a 1.23 sensitivity, while at t = .4 the sensitivity is 2.76.
From this nomograph, it is obvious that FSA participants can easily be too conservative when establishing the designated amount.
in the nomograph, the largest heater temperature is 275 [degrees] C, so it is assumed that the maximum temperature of the polyethylene in the adapted butt fusion model is greater than this temperature.
It was found that the nomographs do work well for the mid-efficiency, noncondensing furnaces, such as Furnaces C and D, generally producing agreement within 1% of the detailed calculations.

This unusual nomograph allows the design engineer to predict the ratio of effective radiated power (ERP) of an on-board jammer to a decoy jammer.
As useful as this nomograph is, more precise solutions to ECM equations may be generated by use of a computer program entitled "[E.sup.3]: ECM Equations by E-Systems." Copies of this IBM compatable software, which solves eight frequently used radar jamming equations, may be obtained at no cost by contacting Ms.
