Modelling Periodic Measurement Data Having a Piecewise Polynomial Trend Using the Method of Variable Projection
Johannes Handler, Dimitar Ninevski, Paul O'Leary
This paper presents a new method for modelling periodic signals having an aperiodic trend, using the method of variable projection. It is a major extension to the IEEE-standard 105…
Detection of Derivative Discontinuities in Observational Data
Dimitar Ninevski, Paul O'Leary
This paper presents a new approach to the detection of discontinuities in the n-th derivative of observational data. This is achieved by performing two polynomial approximations at…
Simultaneous Approximation of Measurement Values and Derivative Data using Discrete Orthogonal Polynomials
Roland Ritt, Matthew Harker, Paul O'Leary
This paper presents a novel method for polynomial approximation (Hermite approximation) using the fusion of value and derivative information. Therefore, the least-squares error in…
Real-Time-Data Analytics in Raw Materials Handling
Christopher Josef Rothschedl, Roland Ritt, Paul O'Leary +3
This paper proposes a system for the ingestion and analysis of real-time sensor and actor data of bulk materials handling plants and machinery. It references issues that concern mi…
Advanced Symbolic Time Series Analysis in Cyber Physical Systems
Roland Ritt, Paul O'Leary, Christopher Josef Rothschedl +1
This paper presents advanced symbolic time series analysis (ASTSA) for large data sets emanating from cyber physical systems (CPS). The definition of CPS most pertinent to this pap…
An Algebraic Framework for the Real-Time Solution of Inverse Problems on Embedded Systems
Christoph Gugg, Matthew Harker, Paul O'Leary +1
This article presents a new approach to the real-time solution of inverse problems on embedded systems. The class of problems addressed corresponds to ordinary differential equatio…
Regularized Reconstruction of a Surface from its Measured Gradient Field
Matthew Harker, Paul O'Leary
This paper presents several new algorithms for the regularized reconstruction of a surface from its measured gradient field. By taking a matrix-algebraic approach, we establish gen…
A Matrix Framework for the Solution of ODEs: Initial-, Boundary-, and Inner-Value Problems
Matthew Harker, Paul O'Leary
A matrix framework is presented for the solution of ODEs, including initial-, boundary and inner-value problems. The framework enables the solution of the ODEs for arbitrary nodes.…
