Rational quadratic spline interpolation to monotonic data. [PDF]
, 1982 In an earlier paper by Gregory & Delbourgo (1982), a piecewise rational quadratic function is developed which produces a monotonic interpolant to monotonic data. This interpolant gives visually pleasing curves and is of continuity class C1 .

Backward transfer influences from quadratic functions instruction on students’ prior ways of covariational reasoning about linear functions [PDF]
The Journal of Mathematical Behavior, 2021 Abstract The study reported in this article examined the ways in which new mathematics learning influences students’ prior ways of reasoning. We conceptualize this kind of influence as a form of transfer of learning called backward transfer. The focus of our study was on students’ covariational reasoning about linear functions before and after they ...

Characterization of solutions of the discrete-time algebraic Riccati equation based on quadratic difference forms [PDF]
, 2006 This paper is concerned with a characterization of all symmetric solutions to the discrete-time algebraic Riccati equation (DARE). Dissipation theory and quadratic difference forms from the behavioral approach play a central role in this paper. Along the

Powering Analysis of Oscillating Foil Moving in Propagating Wave Flow Field [PDF]
한국해양공학회지, 2019 In this study, a two-dimensional oscillating foil with forward speed in a propagating wave flow field was considered. The time-mean power to maintain the heaving and pitching motions of the foil was analyzed using the perturbation theory in an ideal ...
