Dynamic Amplification Factor (DAF) or Dynamic Increase Factor (DIF), is a dimensionless number which describes how many times the deflections or stresses should be multiplied to the deflections or stresses caused by the static loads when a dynamic load is applied on to a structure. [1]
Graphs of dynamic amplification factors vs non-dimensional rise time (t r /T) exist for standard loading functions (for an explanation of rise time, see time history analysis below). Hence the DAF for a given loading can be read from the graph, the static deflection can be easily calculated for simple structures and the dynamic deflection found.
An economic impact analysis only covers specific types of economic activity. Some social impacts that affect a region's quality of life, such as safety and pollution, may be analyzed as part of a social impact assessment, but not an economic impact analysis, even if the economic value of those factors could be quantified.

The specimen showing stable crack growth shows an increasing trend in fracture toughness as the crack length increases (ductile crack extension). This plot of fracture toughness vs crack length is called the resistance (R)-curve. ASTM E561 outlines a procedure for determining toughness vs crack growth curves in materials. [18]
In econometrics, a dynamic factor (also known as a diffusion index) is a series which measures the co-movement of many time series. It is used in certain macroeconomic models. A diffusion index is intended to indicate the changes of the fraction of economic data time series which increase or decrease over the selected time interval,
Growth stocks: A growth stock is one that is expected to increase in value and beat the market, delivering higher-than-average returns over the long term. Growth stocks are typically from ...
In dynamic efficiency, [2] it is impossible to make one generation better off without making any other generation worse off. It is closely related to the notion of "golden rule of saving". In relation to markets, in industrial economics, a common argument is that business concentrations or monopolies may be able to promote dynamic efficiency. [3]
It is the sum of the pure rate of time preference and the growth rate of per capita consumption (), adjusted by the factor (), which represents the impact of economic growth on the discount rate. The next big finding on the climate discount rate was the Stern Review. [41]
