Rational approximation of discrete data with asymptomatic behaviour [PDF]
This thesis is concerned with the least-squares approximation of discrete data that appear to exhibit asymptotic behaviour. In particular, we consider using rational functions as they are able to display a number of types of asymptotic behaviour.

Data‐Driven High‐Throughput Volume Fraction Estimation From X‐Ray Diffraction Patterns
Advanced Intelligent Discovery, EarlyView.Long exposure times and the need for manual evaluation limit the use of X‐ray diffraction in high‐throughput applications. This study presents a data‐driven approach addressing both issues. HiVE (a method for High‐throughput Volume fraction Estimation) performs composition estimation for high‐noise XRD patterns produced using polychromatic emission ...

Weighted simultaneous Chebyshev approximation [PDF]
, 1981 In this paper we discuss the problem of weighted simultaneous Chebyshev approximation to functions f1,…fm ϵ C(X) (1 ⩽ m ⩽ ∞), i.e., we wish to minimize the expression ∥{∑mj = 1 λj¦fj − q¦p}1p∥∞, where λj > 0, ∑mj = 1 λj = 1, p ⩾ 1.

Nonlinear permuted Granger causality
Canadian Journal of Statistics, EarlyView.Abstract Granger causality is an established, contentious method that seeks causal temporal connections via association and precedence. While not true causal inference, it assists in mapping networks of information flow that may warrant further study.
