Modelling non‐linear psychological processes: Reviewing and evaluating non‐parametric approaches and their applicability to intensive longitudinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Psychological concepts are increasingly understood as complex dynamic systems that change over time. To study these complex systems, researchers are increasingly gathering intensive longitudinal data (ILD), revealing non‐linear phenomena such as asymptotic growth, mean‐level switching, and regulatory oscillations.

Data-Driven Fault Detection and Isolation for Multirotor System Using Koopman Operator

Journal of Intelligent and Robotic Systems
This paper presents a data-driven fault detection and isolation (FDI) for a multirotor system using Koopman operator and Luenberger observer. Koopman operator is an infinite-dimensional linear operator that can transform nonlinear dynamical systems into ...

Heterogeneous Mixtures of Dictionary Functions to Approximate Subspace Invariance in Koopman Operators: Why Deep Koopman Operators Work

Journal of Nonlinear Science
Abstract Koopman operators model nonlinear dynamics as a linear dynamic system acting on a nonlinear function as the state. This nonstandard state is often called a Koopman observable and is usually approximated numerically by a superposition of functions drawn from a dictionary. In a widely used algorithm, extended dynamic mode decomposition

Public Theology as Mediation: Navigating the Dutch Protestant Church's Public Calling in a Hypermediated World☆

International Journal of Systematic Theology, EarlyView.
Abstract The article explores Christianity's role in society through public theology, particularly in relation to the public calling of the Protestant Church in the Netherlands (PCN). It advocates for reflecting on the dichotomy of church/world through the lens of divine mediation, challenging traditional dualisms and emphasizing a ‘soft difference ...

Good Public Theology is Twilight Theology. A Constructive Deconstruction of Public Theology

International Journal of Systematic Theology, EarlyView.
Abstract The article outlines the basic features of a good public theology that is inspired by Paul’s description of the situation of the church and Christians: ‘The night has passed, the day is not far distant’ (Rom 13:12). In his analysis of the present, the author identifies eight specific challenges of contemporary culture – challenges that have so

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.
