 Initialized Fractional Calculus 
  The fractional calculus (which admits of integrals and derivatives of noninteger order) dates back almost to the origin of the betterknown ordinary (integerorder) calculus, but thus far has been treated more as a mathematical curiosity than as a scientific and engineering tool. 
  The application of the fractional calculus to scientific and engineering problems has been inhibited by difficulties that arise from the basic definitions given heretofore for integrals and derivatives of arbitrary order. 
  Going beyond viscoelasticity, the initialized fractional calculus can be applied to problems that arise in a variety of scientific, engineering, and purely mathematical disciplines, including creep, percolation, material science, viscous fluid behavior, heat transfer, batteries, electromagnetics, control, communications, filtering, and chaotic systems.
