- Interactive Simulation Systems for Industrial Equipment - Supporting System Verification Through Interactive Information Visualization(2026) Persson, Jakob; Tan Quach, KevinIndustrial process systems rely on precise level measurements to run safely and profitably. To verify that these measuring instruments work correctly under realistic conditions, engineers use simulation setups like the Interactive Plant Environment (IPE). However, exploring the massive amounts of live data generated during these tests is difficult without specialized tools. The primary purpose of this project is to answer how interactive simulation systems should be designed to support system verification. To investigate this, a prototype interface was developed to allow test engineers to easily run automated scripts, control the system manually, and analyze real-time data. Using a Research through Design (RtD) approach and the Double Diamond process, the project started with semi-structured interviews to understand the daily work flows and frustrations of expert test engineers. Insights from this pre-study indicated that standard usability checklists are insufficient for live industrial environments. By combining these empirical findings with foundational Human-Computer Interaction (HCI) principles and Information Visualization (InfoVis) theory, the project introduces a set of custom design guidelines: spatial fidelity and dynamic state mapping, flexible test control, stable views for live data, clear error handling, proactive input validation and defensive safety nets, and data filtering. Based on these guidelines, a functional web application prototype was built featuring visual tank models, live data plotting, and seamless switching between automated and manual execution. A heuristic evaluation of the prototype suggested that the interface supports expert test engineers by reducing cognitive load through visual metaphors and maintaining stable views during live data inspection. While the prototype managed complex testing scenarios, it also exposed vulnerabilities regarding conflicting commands and unguided error recovery, which directly resulted in refining and expanding the guidelines. Ultimately, this project proposes a set of domain-specific guidelines that can assist designers and developers in building interactive simulation and verification systems for similar industrial contexts.
- Bridging Infrastructure; A Broad Study, Applied On Älvängen(2025) Berntsson, HelgeAs society has developed and expanded, the transport network has grown. The small, simple path has turned into a street, and today that street is a motorway that runs straight through the community. This is a common sight in towns that have grown with the car, and it’s a structure that creates infrastructure barriers. An obstacle along someone’s path, creating barrier effects. This structure exists today in Älvängen. The motorway and railway separate large areas next to the town centre, but the barrier effects can be considered minor as there is currently no attraction to the separated areas. This may change if the municipality’s visions for the future are realised. How can barrier effects then be prevented when the need to cross the motorway and railway is created? The foundation of the thesis is based on two theoretial oriented parts, one of which has been to test whether the conceptual model of barrier effects developed by Job van Eldijk as part of his research on infrastructure barriers can be used to develop a needs specification for a specific location, in this case Älvängen. The second part is a study of reference projects, using research for design as a methodology. How have infrastructure barriers been dealt with in different places around the world, and what can we learn from this? The lessons learned from the reference projects have then been used to create a number of design principles that should be taken into account and used when designing new pedestrian and cycle bridges with the aim of reducing barriers. These design principles have then been applied, together with the needs identified for Älvängen, to create a proposal for a new pedestrian and cycle bridge over the motorway and railway in Älvängen. A new pedestrian and cycle bridge that will help the residents of Älvängen to travel between the town centre and the green areas along the Göta Älv river, while minimising any future barrier effects that may arise. Finally, the lessons learned from the project as a whole are summarised, with a strong focus on footbridges, which have become the core of the project.
- Combining Fluorescence and Nanofluidic Scattering Microscopy For Biomolecule Characterization(2026) Sofra, ChristinaCharacterization of single biomolecules is fundamental for understanding biological processes at the molecular level. Although fluorescence microscopy using nanofluidic devices has been a longstanding workhorse for the study of single biomolecules, crucial limitations exist, with the main being alterations in structural conformation due to fluorophore binding. Techniques based on detection of scattering light, such as iSCAT (Interferometric scattering microscopy) microscopy, have emerged and evolved to label-free biolomecular probing techniques. Nanofluidic scattering microscopy (NSM), a technique relying on freely diffusing biomolecules inside nanofluidic structures, has also been developed the last years with impressive results as a reliable label-free characterization method. This thesis investigates the applicability of NSM as a label-free technique for the characterization of single DNA molecules confined inside nanochannels, using fluorescence microscopy as a reference method. Both measurements were performed under comparable experimental conditions to evaluate the capability of both techniques in determining DNA extension. In parallel, a dedicated analysis algorithm was developed for the fluorescence measurement technique, including automated molecular detection, trajectory extraction, and DNA length estimation using errorfunction fitting. Measurements were performed on DNA samples prepared in 0.5×TBE and 0.05×TBE. Fluorescence microscopy showed larger and more variable molecular extensions in 0.05×TBE, while NSM yielded similar median extensions under both conditions, with a broader distribution in 0.05×TBE. Correlated measurements showed a positive relationship between the two methods, although individual discrepancies and potential selection bias require further investigation before quantitative agreement can be established. The fluorescence analysis also requires further optimization for reliable measurements of DNA extension fluctuations. This work establishes an experimental and analytical framework for simultaneous fluorescence microscopy and NSM measurements of confined single DNA molecules.
- SCARS OF SETTLEMENTS; Destruction of mobility, identity, and urban space in Al-Khalil(2025) Barham, IsraThis thesis examines the fragmented urban landscape of Al-Khalil (Hebron), where the Zionist settler-colonial state («Israel») imposes severe restrictions on Palestinian mobility. Through architecture, urban planning, and physical barriers such as checkpoints, settlements, and militazy zones, the occupation reshapes daily life and transforms the relationship between people, space, and identity. My research focuses on how these spatial practices operate as tools of control, and how they affect the social fabric, sense of belonging, and lived realities of Palestinians. Because of the ongoing genocide in Ghaza (Gaza) (Amnesty International, 2024; Office of the United Nations High Commissioner for Human Rights, 2024) and the vulnerability of conducting on field research as a Palestinian myself, the study utilizes remote research methods. Conversations with Palestinian people, both who were and who are still in Al-Khalil, combined with mapping tools, provide critical insights into the social, psychological, and spatial effects of these restrictions and the highly oppressive spatial interventions. In addition to that, this research aims to raise awareness of how architecture functions as a tool of power and domination, emphasizing the need for a more conscious engagement with the built environment in contexts of occupation and segregation. Methodologically, the thesis is grounded in narrative and decolonial approaches, drawing on indigenous Storywork (Archibald, 2008), narrative analysis (Czarniawska, 2004), and decolonizing methodologies (Smith, 2022). These frameworks guide me to treat testimonies not as data but as living knowledge. Storytelling becomes central in my thesis. Tatreez (Palestinian embroidery) is woven into this process as both symbol and method. Through the slow, repetitive act of stitching in response to each testimony, I engaged with the stories in a way that allowed me to listen through the hands as well as the mind. The resulting visual works combined with Tatreez serve as another layer of interpretation, translating lived experiences into material form. By documenting the realities of daily life under occupation,and by centering Palestinian storytelling and embodied forms of making, I aim to contribute to a broader discussion on spatial justice, highlighting how architecture is used as a mechanism of domination, while also foregrounding the resilience, memory, and lived knowledge of Palestinians navigating an environment structured to control them.
