Running towards: Labour market incentives for runaway slaves in the British Cape Colony, 1830–1838

Asia‐Pacific Economic History Review, EarlyView.
Abstract Recent scholarship on slave escapes has increasingly emphasised economic motivation, but few studies have empirically investigated how market incentives influenced the decision‐making of enslaved individuals during transitions from coerced to wage labour.

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.

Data-Driven Identification of Gas Turbine Engine Dynamics via Koopman Operator Genetic Algorithm

IEEE Access
Gas turbine engines (GTEs) are highly nonlinear control-nonaffine systems. Deriving their physics-based models can be challenging, particularly when some critical parameters can be difficult to measure or determine otherwise.

Two Roads to Koopman Operator Theory for Control: Infinite Input Sequences and Operator Families

CoRR
The Koopman operator, originally defined for dynamical systems without input, has inspired many applications in control. Yet, the theoretical foundations underpinning this progress in control remain underdeveloped. This paper investigates the theoretical structure and connections between two extensions of Koopman theory to control: (i) Koopman operator

From the ICU Bedside: Applying the Transnational Clinical Academic Doctorate Lens to a Clinically Embedded PhD Journey

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim To critically reflect on a transnational, clinically embedded doctoral journey undertaken during and after the COVID‐19 pandemic, and to draw conceptual and systemic lessons for doctoral education and clinical academic nursing pathways. Background Reflective accounts of doctoral study exist, yet few examine practice‐based PhDs conducted ...

Introduction to the Koopman operator in Systems and Control

, 2018
The Koopman operator is a linear, infinite-dimensional operator defined for a nonlinear dynamical system. Through this linear operator, we can exploit established linear techniques (e.g.

Data-Driven Nonlinear Stabilization Using Koopman Operator

, 2019
We propose the application of Koopman operator theory for the design of stabilizing feedback controller for a nonlinear control system. The proposed approach is data-driven and relies on the use of time-series data generated from the control dynamical ...

Deep Bilinear Koopman Model for Real-Time Vehicle Control in Frenet Frame

IEEE Access
Accurate modeling and control of autonomous vehicles remain a fundamental challenge due to the nonlinear and coupled nature of vehicle dynamics. While Koopman operator theory offers a framework for deploying powerful linear control techniques, learning a

Demographic Dynamics and International Trade: Stylized Facts and Theoretical Insights

Journal of Economic Surveys, EarlyView.
ABSTRACT Demographic change within a country has economic repercussions for other countries through international transactions. Ongoing shifts in population size and age structure across countries have important implications for international trade, operating through changes in market size, consumption preferences, and labor supply.
