Constrained trajectory synthesis via quasi-interpolation
IEEE Conference on Decision and Control, 2022In this article we introduce QuITO — Quasi-Interpolation based Trajectory Optimization, a direct multiple shooting algorithm to solve a class of constrained nonlinear minimum energy optimal control problems.

The quasi-interpolation operators introduced in Chapter 22 are \(L^1\)-stable, are projections and have optimal (local) approximation properties. However, they do not commute with the usual differential operators (gradient, curl, and divergence), which makes them difficult to use to approximate simultaneously a vector-valued function and its curl or ...

Quasi Interpolation With Voronoi Splines
IEEE Transactions on Visualization and Computer Graphics, 2011We present a quasi interpolation framework that attains the optimal approximation-order of Voronoi splines for reconstruction of volumetric data sampled on general lattices. The quasi interpolation framework of Voronoi splines provides an unbiased reconstruction method across various lattices.

Purpose The purpose of this study is to extend the cubic B-spline quasi-interpolation (CBSQI) method via Kronecker product for solving 2D unsteady advection-diffusion equation. The CBSQI method has been used for solving 1D problems in literature so far.

Quasi-interpolation for high-dimensional function approximation
Numerische MathematikThe paper proposes a general quasi-interpolation scheme for high-dimensional function approximation. To facilitate error analysis, we view our quasi-interpolation as a two-step procedure.
