Iterated Bernstein Polynomial Approximations
2018Kelisky and Rivlin [7] proved that each Bernstein operator \(B_n\) is a weaky Picard operator (WPO). Moreover, given \(n\in \mathbb {N}\) and \(\varphi \in C([0,1];\mathbb {R})\), $$ \lim _{j\rightarrow \infty }(B_n^j\varphi )(t) = \varphi (0) + (\varphi (1)- \varphi (0))t, \quad t \in [0, 1]. $$

Approximate 3D iterative reconstruction for SPECT
Medical Physics, 1997Compared with slice‐by‐slice approaches for SPECT reconstruction, three‐dimensional iterative methods provide a more accurate physical model and an improved SPECT image. Clinical application of these methods, however, is limited primarily by their computational demands.

Approximating Handwritten Curve by Using Progressive-Iterative Approximation
2013 10th International Conference Computer Graphics, Imaging and Visualization, 2013In this paper, a given handwritten curve will be approximately converted into a Bezier curve. First, a number of sampled points on the given curve are systematically chosen to guarantee that the Bezier curve can be adequately modeled without the loss of curve characteristics. These points are considered to be the Bezier control points.

Approximation by Neural Networks Iterates
2013Here we study the multivariate quantitative approximation of real valued continuous multivariate functions on a box or ℝ N , N∈ℕ, by the multivariate quasi-interpolation sigmoidal and hyperbolic tangent iterated neural network operators. This approximation is derived by establishing multidimensional Jackson type inequalities involving the multivariate ...

Iterative approximations for queueing networks
1986If networks of queues satisfy certain conditions, then the equilibrium distribution for the number of jobs in the various stations has the so-called product-form. In such cases there are relatively elegant and simple computational procedures for the relevant behavioral characteristics.
