  New algorithms for fast wavelet transforms with biorthogonal spline wavelets
on nonuniform grids are presented. In contrary to classical wavelet transforms,
the algorithms are not based on filter coefficients, but on algorithms for
B-spline expansions (differentiation, Oslo algorithm, etc.). Due to inherent
properties of the spline wavelets, the algorithm can be modified for spline
grid refinement or coarsening. The performance of the algorithms is
demonstrated by numerical tests of the adaptive spline methods in circuit
simulation.
