1. (Mechanical Engineering) any one of a series of narrow keys (external splines) formed longitudinally around the circumference of a shaft that fit into corresponding grooves (internal splines) in a mating part: used to prevent movement between two parts, esp in transmitting torque
2. a long narrow strip of wood, metal, etc; slat
3. (Building) a thin narrow strip made of wood, metal, or plastic fitted into a groove in the edge of a board, tile, etc, to connect it to another
vb
(Building) (tr) to provide (a shaft, part, etc) with splines
[C18: East Anglian dialect; perhaps related to Old English splin spindle; see splint]
This latter fact means that in the approximation expression in (8) we should retain the left inhomogeneous cubic B-spline for the constant harmonic and eliminate it for other harmonics for both Dirichlet and Neumann problems.
For the above, the NURBS (nonuniform Rational B-Spline) surface fitting algorithm that guarantees the accuracy of positions and shapes of array elements and the local model reconstruction algorithm that ensures the accuracy of amplitudes and phases of feed connectors are proposed.
where x and [xi] are the points in the domain or its boundary, the integration is over the boundary, S, of the domain, and G and T are the associated B-spline fundamental solutions, as reported in [23].
