Finite Element Simulations for the Design of Therapeutic Approaches for Retinal Diseases
(2022)
The retinal disease age-related macular degeneration is the most common cause of vision loss in industrialized countries. In this thesis, motivated by the drug (antibody) treatment of this disease, we designed long-term three dimensional Finite Element simulations of the drug distribution in the healthy human eye. The underlying model consists of a time-dependent convection-diffusion equation coupled to a stationary Darcy equation describing the flow of the aqueous humor through the vitreous medium. We replaced the ...

Attribute Exploration with Multiple Experts
(2023)
Attribute exploration is a knowledge acquisition method from the realm of formal concept analysis that allows a domain expert to efficiently uncover the dependencies in a domain. It is based on a question-answering scheme where the exploration algorithm generates questions about dependencies in the domain that are then answered by a domain expert. Even though many variants and extension to this were developed, only few attempts to incorporate multiple experts were made. The overarching goal of this thesis is to extend ...

Application of Temporal Airy Pulses for investigating the origin of Laser Induced Periodic Surface Structures and for developing new tools in cell surgery and malignant tissue identification
(2023)
In this thesis, ultrashort Temporal Airy Pulses are used to study Laser Induced Periodic Surface Structures (LIPSS) in Part I and to enable the photoinjection of fluorescent markers into single living cells in Part II, Chapter 8. In both cases, the laser pulse excites a dielectric material (fused silica and water) and the special spatio-temporal dynamics of the interaction of a Temporal Airy Pulse with the dielectric is exploited to extend the shape of the excited region along the axis of laser propagation. For the ...

„Jetzt kommt da so ne fremde Frau.“ Eine qualitative Analyse zur Beziehungsgestaltung in der ehrenamtlichen Betreuung von Menschen mit Demenz
(2023-06)
Angesichts der steigenden Demenzprävalenz gilt die Sicherstellung einer angemessenen Versorgung von Menschen mit Demenz als besondere Herausforderung unserer Zeit. Um die häusliche Sorge zu stärken und pflegende Angehörig zu entlasten, bietet die Pflegeversicherung Betreuungsleistungen als niedrigschwellige Unterstützung an. Nach § 45a SGB XI können Ehrenamtliche diese Leistung erbringen und Menschen mit Demenz stundenweise betreuen.
Die Dissertation stellt die bislang kaum erforschte soziale Beziehung zwischen den ...

Market-driven harvesting of non-timber forest products and the governance of communal forests in the south-east lowveld of Zimbabwe.
(2023-07)
Despite forests providing a wide range of important products and services for much of Zimbabwe’s population, natural forests are threatened by deforestation. The highest rates of deforestation occur in communal forests. Communal forest resources in Zimbabwe show evidence of increased degradation and signs of a breakdown of local institutions for resources management. These signs of a breakdown of local institutions are coupled with evidence of a lack of any emerging alternative institutions for conservation of forest ...

Situative Teams in Cooperative Autonomous Systems
(2023)
Distributed systems have been established in many areas of IT and will play an even more significant role in the future. Such systems are no longer limited to specific fields of application but interconnect many different domains. They encompass, e. g. Cloud Computing, Internet of Things, service robotics, and autonomous vehicles. The integrated sub-systems communicate in order to exchange information and, if necessary, perform tasks together. Moreover, the number of interconnected sub-systems is constantly growing. ...

Control of Open Quantum Systems: Examples & Methods for Non-Markovian Dynamics
(2023)
Usually open quantum systems are considered to be under the influence of noise and therefore faulty. On the other hand, a controlled system is regarded as something stable and predictable. It is often neglected, that the two aspects are very closely related. A perfectly isolated quantum system will not be subject to environmental influences, but this makes it also impossible to interact with it in any manner. Controlling and measuring such a system is impossible and therefore of no technical relevance. Every system ...

Investigation of Multiphase Power Converter using Integrated Coupled Inductor Regarding Electric Vehicle Application
(2016-05-10)
The challenge of reducing carbon emission and achieving emission target until 2050, has become a key development strategy of energy distribution for each country. The automotive industries, as the important portion of implementing energy requirements, are making some related researches to meet energy requirements and customer requirements. For modern energy requirements, it should be clean, green and renewable. For customer requirements, it should be economic, reliable and long life time. Regarding increasing ...

Conputational Linguistic Approach to Implicit Sentiment Analysis: Politeness and Sentiment Interaction
(2022)
Sentiment analysis is a hot topic in many research fields such as linguistics, computer science and marketing. With the development of technology, machines can reach very high performance on explicit sentiment analysis both sentence-level and aspect-level. The role of computational linguists has also changed from handcrafting scoring rules to guide training data annotation as the algorithms are developed from rule-based scoring to deep learning models that can extract language features themselves. Moreover, research ...

Räumliche Wahlmöglichkeiten als Effizienzkriterium für Siedlung und Verkehr
(2006-11-01)
In der Arbeit wird eine Messgröße für die Mobilität im Personenverkehr formuliert und anhand dieser Messgröße eine vergleichende Bewertung von Szenarien der Siedlungs- und Verkehrsentwicklung vorgenommen.
Mobilität im Sinne räumlicher Wahlmöglichkeiten sind die Freiheitsgrade der Menschen in der Auswahl ihrer räumlichen Ziele und Beziehungen. Mehr als das tatsächliche Verhalten unterliegen Wahlmöglichkeiten starken Einflüssen der Siedlungsstruktur. Die relevanten Siedlungsstrukturmerkmale werden zu zwei Hauptmerkmalen ...
