A method based on the singular perturbation theory and the averaging method is developed for the dynamic analysis of hydraulic valves. Periodic solutions are calculated and stability is analyzed under the influence of ...
Deep Learning based Vehicle Detection in Aerial Imagery
(2022)
This book proposes a novel deep learning based detection method, focusing on vehicle detection in aerial imagery recorded in top view. The base detection framework is extended by two novel components to improve the detection ...
Trajectory optimization based on recursive B-spline approximation for automated longitudinal control of a battery electric vehicle
(2024)
This work describes a method for weighted least squares approximation of an unbounded number of data points using a B-spline function. The method can shift the bounded B-spline function definition range during run-time. ...
Optical coherence tomography for characterization of nanocomposite materials
(2021)
Major challenges in nanoparticle and nanocomposite development are the control of particle size and shape, and to achieve uniform particle dispersion. In this book, the application of optical coherence tomography (OCT) for ...
In Search of Meaning
(2009)
The essays collected in this volume explore some of the themes that have been at the centre of recent debates within Wittgensteinian scholarship. In opposition to what we are tentatively inclined to think, the articles of ...
Manchester Ship Canal
(2021)
This book investigates how urban/rural patterns provide differing conditions for living and working. The project is to read and analyse these urban/rural settlement structures and provide insight into the patterns of living ...
Integrierte Projektabwicklung mit Mehrparteienverträgen
(2024)
In the context of IPA projects, project participants generally try to create a system that aligns the individual interests of the participants in such a way that opportunistic behavior of the participants does not have ...
