SHAPE DESIGN OF 3D-CONCRETE-PRINTED MASONRY STRUCTURES
(2023)The research aims to contribute to the ‘digitalisation’ of concrete – digital design of 3D concrete-printed (3DCP) structures and robotic manufacture of the concrete parts – and thus pave the way for its sustainable use. The motivation to achieve such a Sustainable Digital Concrete (SDC) stems from three insights: The importance of a common language of geometry to empower a collaborative approach between Architecture, Engineering and ...Doctoral Thesis -
In-situ laser powder bed fusion process monitoring and control
(2023)This dissertation addresses the issue of process monitoring and control in the additive manufacturing process of metal laser powder bed fusion (L-PBF). The acceptance of this branch of additive manufacturing as a serious manufacturing method suffers in high technology industries such as for example aerospace and medical, but conventional users are also tentative regarding widespread application of this novel process. Two major factors ...Doctoral Thesis -

Right message, right people, right time: The design and implementation of chatbot-led interventions for mass market settings.
(2023)Chatbots are prevalent in service encounters, yet to date, there exist few theory-led approaches to their successful design and implementation for mass market settings that move beyond simple ascriptions of anthropomorphism. In the current thesis, the author explores three perspectives elucidating chatbot design, recruitment, and implementation: In the right message section, qualities of the message and messenger are investigated, showing ...Doctoral Thesis -
Collectives to capital: Institutional, forest, and farm transitions in Georgia
(2023)The Caucasus is a mountainous region between Europe and Asia recognized for its biological and cultural diversity. Its ecosystems harbor high concentrations of endemic species and provide an abundance of ecosystem services, yet are significantly understudied compared to other ecosystems in Eurasia. The region has experienced dramatic changes over thirty years beginning with the collapse of the Soviet Union and followed by armed conflicts ...Doctoral Thesis -
Design for Additive Manufacturing of Compliant Mechanisms
(2023)Additive manufacturing (AM) has the potential to revolutionize the design and fabrication of compliant mechanisms (CMs). CMs are monolithic mechanisms that use compliant structures to achieve the desired functional behavior. Their single-part nature is beneficial for various applications as it does not experience friction, wear, stick-slip effects and does not require lubrication. The layer-by-layer nature of AM provides significant design ...Doctoral Thesis -
HEART AND BRAIN: THE PHYSIOLOGICAL AND NEURAL SIGNATURES OF LEARNING MATHEMATICS
(2023)This study makes three interrelated contributions pertinent to neurocognition and neurophysiology in learning. These contributions were carried out in the form of three projects that examined the neural and physiological basis of learning mathematics. The first project is a systematic investigation of neural and physiological measurements taken while learning. A systematic review was conducted of previous literature documenting heartbeats ...Doctoral Thesis -
Useable Fully Homomorphic Encryption
(2023)Fully Homomorphic Encryption (FHE) enables arbitrary computations to be performed over encrypted data, eliminating the need to decrypt the data and expose it to potential risk while in use. FHE promises to significantly broaden the range of applications that can be secured with End-to-End encryption. In the last decade, FHE has undergone several breakthroughs and advancements that led to a leap in performance improvements, enabling a ...Doctoral Thesis -
On Challenges of Image Features for Cloud-Based Localization and Mapping
(2023)Visual Localization and Mapping is a long-standing problem in Computer Vision with high relevance in Robotics and Augmented Reality (AR) applications. Most state-of-the-art approaches build upon image features due to their efficiency, versatility, and scalability. Despite tremendous progress by the community over the last decades, recent benchmarks show that current methods still struggle with robustness and accuracy on real-world data. ...Doctoral Thesis -
Improved Approximations for Connectivity Augmentation Problems
(2023)We consider the Connectivity Augmentation Problem (CAP), a classical problem in the area of Survivable Network Design. It is about increasing the edge-connectivity of a graph by one unit in the cheapest possible way. More precisely, given a k-edge-connected graph G = (V, E) and a set of extra edges, the task is to find a minimum cardinality subset of extra edges whose addition to G makes the graph (k + 1)-edge-connected. If k is odd, the ...Doctoral Thesis -
Closing the Gap: Understanding the Impact of Fragmented Land Surface Observations and Data-Driven Strategies for Consolidation
(2023)The current climate crisis on land is visible in rising land temperatures, drying trends in many regions, and increased likelihood of droughts and heatwaves now and in the future. The observational record of the feedback mechanisms at the land surface leading to these changes is however highly fragmented. Ground observations are unequally distributed and sparse. Remotely sensed observations suffer from retrieval limitations and contain ...Doctoral Thesis -
Interactive Language-Based Agents
(2023)Deep neural network architectures have led to remarkable achievements in the area of natural language processing (NLP) in recent years. Through scaling up the model size and self-supervised pre-training on the vast amount of textual data available on the internet, generalization and complex reasoning capabilities have been unlocked, even when provided with a small number of specific examples. However, most progress in NLP has been made ...Doctoral Thesis -

Equilibrium as the common ground: Embodied perception-informed structural design
(2023)When designing structures, the expressiveness of the structure should not be underestimated. Many pioneering architects and engineers in the 20th century had already emphasised the artistic aspect of structures and endeavoured to integrate it into architectural space. This thesis begins by exploring the often overlooked and at the same time ambiguous perspective on structural expression in architectural design, revealing that the expressive ...Doctoral Thesis -
