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 ...
Hochgenaue und robuste odometriebasierte Lokalisierung in einem Parkvorgang
(2025)
As part of this work, a special vehicle movement model is being developed for future parking applications. It uses standard sensor technology and requires hardly any additional computing power. An adaptive localization ...
Facility Location Planning in Relief Logistics: Decision Support for German Authorities
(2022)
The delivery of essential goods to beneficiaries in the aftermath of a disaster is one of the main objectives of relief logistics. Thereby, the present work aims to improve relief logistics by improving the location selection ...
Entwicklung eines Messsystems zur modalbasierten Schädigungsanalyse von Brückenüberbauten
(2022)
Bridges are key components of infrastructure networks, which are the basic prerequisite for a prospering economy. Regarding maintenance scheduling, profound knowledge of the current bridge condition is of high interest. ...
Everlasting Energy
(2025)
In this volume, colleagues and friends of Prof. Dr.-Ing. Robert Stieglitz, who died suddenly and unexpectedly on 6 December 2023, pay tribute to his life and his extraordinary achievements as an internationally recognised ...
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 ...
Belief State Planning for Autonomous Driving
(2021)
This work presents a behavior planning algorithm for automated driving in urban environments with an uncertain and dynamic nature. The algorithm allows to consider the prediction uncertainty (e.g. different intentions), ...
Local Probing of a Superconductor’s Quasiparticles and Bosonic Excitations with a Scanning Tunnelling Microscope
(2023)
Complementary to scattering techniques, scanning tunnelling microscopy provides atomic-scale real space information about a material's electronic state of matter. State-of-the-art designs of a scanning tunnelling microscope ...
Herstellung dünner Folien aus Lithium-Lanthan-Titanat zur Anwendung als Festkörperelektrolyt
(2022)
In this work the production of a thin film of lithium lanthanum titanate by tape casting for use in a lithium ion solid state battery is described. The influence of the composition of the slip on its flow properties is ...
Thermodynamik von Kobaltoxid Anodenmaterialien für Lithium-Ionen-Batterien und ihr elektrochemisches Verhalten
(2020)
A thermodynamic approach is used to gain new insights into reaction mechanism and correlations between electrochemical and thermodynamic properties of conversion electrodes in the material system Li-Co-O. For this purpose, ...
Thermische Untersuchungen an Laser-aktivierten Leuchtstoff-Systemen mit dynamischer Leuchtdichteverteilung
(2023)
The simulation of ceramic phosphors by means of the diffusion approximation of the radiation transport equation is extended from rotationally symmetrical cases to general, three-dimensional problems. The phosphor is simulated ...
