Weierstrass and Approximation Theory
Journal of Approximation Theory, 2000 This is a lovely article on Weierstrass and the early development of approximation theory. It begins with a short biography of Weierstrass. Two main themes stand out in his work: To set a new standard of rigor in analysis, and his love for power series or more generally for function series.

Accuracy Assessment of LiDAR-Derived Digital Elevation Models Based on Approximation Theory
Remote Sensing, 2015 The cumulative error at a point in a LiDAR-derived DEM consists of three components: propagated LiDAR-sensor error, propagated ground error, and interpolation error.

Recent theories and applications in approximation theory. [PDF]
ScientificWorldJournal, 2015 Approximation theory is a deep theoretical study of methods that use numerical approximation for the problems of mathematical analysis. In practical use, it is typically the application of computer simulation and other forms of computation to problems in various scientific disciplines.

Algorithms and error bounds for multivariate piecewise constant approximation [PDF]
, 2011 We review the surprisingly rich theory of approximation of functions of many vari- ables by piecewise constants. This covers for example the Sobolev-Poincar´e inequalities, parts of the theory of nonlinear approximation, Haar wavelets and tree ...

Generalised discretisation of continuous-time distributions
The Journal of Engineering, 2020 In this study, the definition of discretisation that was proposed recently for continuous-time distributions is made applicable not only to ordinary functions but to a variety of distributions including weak derivatives such that they could be viewed ...

On boundedness inequalities in the variation of certain Schurer-type operators; pp. 1–9 [PDF]
Proceedings of the Estonian Academy of Sciences, 2016 This paper is concerned with boundedness inequalities in the variation for the higher order derivatives of general Schurertype operators. In particular, the boundedness inequalities in the variation for the higher order derivatives of the Bernsteinâ ...
