Query: Box-counting dimension of solution curves for a class of two-dimensional
  nonautonomous linear differential systems   A class of two-dimensional linear differential systems is considered. The
box-counting dimension of the graphs of solution curves is calculated. Criteria
to obtain the box-counting dimension of spirals are also established.
