In its simplest implementation for linear cases such as lines, the DDA algorithm interpolates values in interval by computing for each x i the equations x i = x i−1 + 1, y i = y i−1 + m, where m is the slope of the line. This slope can be expressed in DDA as follows:
One of the inspirations for ENIAC was the mechanical analog Bush differential analyzer. It influenced both the architecture and programming method chosen. However, although ENIAC as originally configured, could have been programmed as a DDA (the "numerical integrator" in Electronic Numerical Integrator And Computer), [2] there is no evidence that it ever actually was.
Discontinuous deformation analysis (DDA) is a type of discrete element method (DEM) originally proposed by Shi [1] in 1988. DDA is somewhat similar to the finite element method for solving stress-displacement problems, but accounts for the interaction of independent particles (blocks) along discontinuities in fractured and jointed rock masses.
In computer graphics, a line drawing algorithm is an algorithm for approximating a line segment on discrete graphical media, such as pixel-based displays and printers. On such media, line drawing requires an approximation (in nontrivial cases). Basic algorithms rasterize lines in one color.
Depending on the type of DDA you have, you may be able to use it to: Withdraw cash from an ATM or bank branch. Make purchases using a debit card. Pay bills. Write checks. Deposit checks.

From January 2008 to December 2012, if you bought shares in companies when Victor J. Dzau joined the board, and sold them when he left, you would have a -10.4 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
