Koopman Explicit Model Following Control Framework for a Robotic Manipulator

IEEE Access
Robotic manipulators have nonlinear and coupled dynamics, and this situation makes accurate modeling and control difficult under parameter uncertainties and external effects.

Data‐driven sensor fault detection and isolation of nonlinear systems: Deep neural‐network Koopman operator

IET Control Theory & Applications, 2023
This paper proposes a data‐driven sensor fault detection and isolation approach for the general class of nonlinear systems. The proposed method uses deep neural network architecture to obtain an invariant set of basis functions for the Koopman operator ...

Measuring Teamwork Competencies Cross‐Culturally Through Computerized Adaptive Testing: Implications for Human Resource Management

Human Resource Management Journal, EarlyView.
ABSTRACT This article examines the psychometric properties of a Computerized Adaptive Test for Measuring Teamwork Competencies (CAT‐TWC). Using item response theory and a multicultural team framework, we examine the dimensionality, precision, and measurement invariance of the measures obtained with the CAT‐TWC in a first study with participants from ...

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Volunteering While Researching Conflict and Violence: Reflections on Listening, Solidarity, and Decoloniality in Myanmar's Borderlands

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Scholars working on conflict and violence often engage with local organisations, yet the methodological and ethical implications of volunteering‐while‐researching are rarely discussed in writing. This article contributes to debates on decolonizing research by conceptualising volunteering‐while‐researching as a practice that—while imbued with ...

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.

From Block-Oriented Models to the Koopman Operator: A Comprehensive Review on Data-Driven Chemical Reactor Modeling

Mathematics
Some chemical reactors exhibit coupled dynamics with multiple equilibrium points and strong nonlinearities. The accurate modeling of these dynamics is crucial to optimal control and increasing the reactor’s economic performance. While neural networks can

Koopman Operators in Robot Learning

Koopman operator theory offers a rigorous treatment of dynamics and has been emerging as an alternative modeling and learning-based control method across various robotics sub-domains. Due to its ability to represent nonlinear dynamics as a linear (but higher-dimensional) operator, Koopman theory offers a fresh lens through which to understand and ...

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.
