Inspired by the fast digitalization during the Covid-19 crisis, we investigate a key aspect of digital transformation of higher education – the emergence of a digital learning space. In developing our analysis, we focus on two streams of digitaliza

In this paper we present a method for simultaneous simplification of a collection of piecewise linear curves in the plane. The method is based on triangulations, and the main purpose is to remove line segments from the piecewise linear curves without

An adaptive method for approximating huge scattered data sets is presented. The approximation scheme generates multilevel triangulations obtained using a subdivision scheme known as longest edge bisection. Nested function spaces are defined over the

We present a three-stage scheme for constructing smooth grid functions approximating data defined over scattered point sets in Rs. The scheme is useful for approximating large scattered data sets and is particularly successful when the data points ar

In this paper, we present a class of decomposition techniques for data represented as matrices. The main idea is to transform a matrix into a sequence of components in order to represent and analyze the matrix in a multi-resolution setting. Data redu

In this paper we look at some iterative interpolation schemes and investigate how they may be used in data compression. In particular, we use the pointwise polynomial interpolation method to decompose discrete data into a sequence of difference vecto

We present a computational study of box spline interpolation in two space dimensions. We are in particular concerned with the problem of computing the box spline coefficients in the presence of large data sets. The issues of convergence and regularit

Multivariate grid point interpolation on finite regions is considered by translates of $C^1 $ box splines defined on a $(s + 1)$-direction mesh in $\mathbb{R}^s $. In general, this problem will give more degrees of freedom than the number of interpol

Funding is one of the very few problems that every researcher on the planet has in common. Most will have to confront this burden repeatedly during their careers, and a dream of a grand solution is common amongst researchers. We have lived that dream
