  • double refraction — the separation of a ray of light into two unequally refracted, plane-polarized rays of orthogonal polarizations, occurring in crystals in which the velocity of light rays is not the same in all directions.
  • double track line — a railway line with double track
  • droplet infection — infection spread by airborne droplets of secretions from the nose, throat, or lungs.
  • dynamic execution — (processor)   A combination of techniques - multiple branch prediction, data flow analysis and speculative execution. Intel implemented Dynamic Execution in the P6 after analysing the execution of billions of lines of code.
  • education contact — (job)   The person at a company who should receive educational material.
  • electrodeposition — The deposition of a metal on a cathode during electrolysis; used as a method of purification.

  • enforcement order — an order by a court to force a person or organization to comply with a regulation or law
  • exception handler — Special code which is called when an exception occurs during the execution of a program. If the programmer does not provide a handler for a given exception, a built-in system exception handler will usually be called resulting in abortion of the program run and some kind of error indication being returned to the user. Examples of exception handler mechanisms are Unix's signal calls and Lisp's catch and throw.

  • foundation course — A foundation course is a course that you do at some colleges and universities in order to prepare yourself for a longer or more advanced course.
  • fractal dimension — (mathematics)   A common type of fractal dimension is the Hausdorff-Besicovich Dimension, but there are several different ways of computing fractal dimension. Fractal dimension can be calculated by taking the limit of the quotient of the log change in object size and the log change in measurement scale, as the measurement scale approaches zero. The differences come in what is exactly meant by "object size" and what is meant by "measurement scale" and how to get an average number out of many different parts of a geometrical object. Fractal dimensions quantify the static *geometry* of an object. For example, consider a straight line. Now blow up the line by a factor of two. The line is now twice as long as before. Log 2 / Log 2 = 1, corresponding to dimension 1. Consider a square. Now blow up the square by a factor of two. The square is now 4 times as large as before (i.e. 4 original squares can be placed on the original square). Log 4 / log 2 = 2, corresponding to dimension 2 for the square. Consider a snowflake curve formed by repeatedly replacing ___ with _/\_, where each of the 4 new lines is 1/3 the length of the old line. Blowing up the snowflake curve by a factor of 3 results in a snowflake curve 4 times as large (one of the old snowflake curves can be placed on each of the 4 segments _/\_). Log 4 / log 3 = 1.261... Since the dimension 1.261 is larger than the dimension 1 of the lines making up the curve, the snowflake curve is a fractal. [sci.fractals FAQ].
