Epilepsy is characterised by unpredictable seizures that significantly impact the quality of life. Although today’s wearable technology is able to continuously monitor physiological data such as heart rate, respiratory rate, motion, and sleep, these data alone often lack the contextual information required to understand triggers related to an individual’s epilepsy. There is an opportunity to record subjective experiences and accurately align these events with their corresponding physiological data to analyse epileptic triggers and generate preventive warnings related to an individual’s historical physiological conditions.

This graduation project addresses this opportunity by designing and evaluating a journal application as a method to integrate physiological data from a wearable with subjective contextual information through a mobile application and Apple Watch. The goal is to create a time-synchronized data set that can be used to train personalised machine learning models capable of predicting seizures and generating preventive warnings.

The proposed design enables epilepsy patients to remotely log scenarios in real time while a wearable continuously measures physiological data types. These two data streams are synchronized through precise timestamps. Once the data is labeled, it is suitable for future machine learning purposes.

The research study of this project focuses on the nudging strategy of the developed mobile application. A usability study was performed with 7 participants to evaluate which type of nudging strategy yields the best user engagement and journaling compliance through the mobile application.
In a within-subjects study (N=7, three conditions for a total of 9 days), no significant differences were found between nudging strategies for the total amount of logged labels, total time covered with labels, or latency. However, a small positive trend has been observed suggesting that a personalised approach yields the best journaling behaviour, indicating that in future research, with a larger sample size, the significant difference between nudge strategies could be proven.

In conclusion, this thesis describes the iterative development of a mobile application able to align subjective contextual information to continuously measured physiological wearable data. Classification of the physiological data with subjective contextual information enables future personalised machine learning applications that support the identification, detection, and forecasting of epileptic-related triggers and seizures. The design balances an epileptic safe interface, user engagement, data processing, and interpretable data visualisation.

Ensuring the long-term reliability of ageing concrete infrastructure has increased the demand for effective Structural Health Monitoring methods capable of detecting internal damage at early stages. One promising technique involves the use of Smart Aggregates (SA) to monitor changes within the structure non-destructively. This study focuses on their application in composite precast concrete beams made continuous, particularly at the concrete-to-concrete interface between the precast inverted T-beam and the cast-in-situ topping layer. This interface is vulnerable to degradation due to shear forces and stress concentrations, which can result in internal defects such as microcracking or interface separation—forms of damage that are important to monitor, yet difficult to assess in practical in-situ conditions.

The aim of this study is to evaluate how SA-based ultrasonic monitoring can be effectively utilised to detect, localise, and characterise interface delamination in composite precast concrete beams made continuous. Focus is placed on assessing the complementary capabilities of Ultrasonic Pulse Velocity (UPV), in terms of spatial localisation, and Coda Wave Interferometry (CWI)-derived indicators, in terms of sensitivity to early-stage damage. Additionally, the study evaluates how ray-path and tomographic visualisation approaches support the interpretation of these ultrasonic techniques.

UPV is applied by analysing changes in wave arrival time to determine variations in propagation velocity, enabling detection of discontinuities along defined transmission paths. In contrast, CWI utilises the sensitivity of microcracking and stress redistribution to detect incremental changes within the material. From these methods, three ultrasonic indicators are derived: relative velocity from UPV, and the correlation coefficient (CC) and relative velocity change (ε) from CWI. These indicators are analysed through ray-path representations, which preserve path-based physical meaning. Additionally, UPV results are reconstructed into a tomographic visualisation to provide a spatial representation of internal structural changes, from which the interface time interference indicator is derived to assess interface delamination.

The experimental program consists of large-scale precast girders made continuous, embedded with SA and subjected to staged loading. The experimental work was conducted as part of a broader research campaign at TU Delft, in which the physical experiments were carried out by M. Ibrahim. Ultrasonic measurements are collected and processed using the described methods, and the resulting indicators are compared with Digital Image Correlation measurements for validation. This approach enables assessment of the capability of ultrasonic indicators to detect, localise, and quantify damage progression at the interface.

The results show that the ultrasonic indicators provide distinct yet complementary insight into structural behaviour. CWI-based indicators demonstrate high sensitivity to early-stage changes: ε responds to early disturbances prior to visible damage, while CC provides a clearer and more consistent indication of crack initiation. In contrast, UPV-derived relative velocity correlates strongly with developed cracking and provides reliable localisation along transmission paths, particularly for sensor pairs oriented to capture flexural and shear cracks. However, sensor pairs crossing the interface show reduced capability in distinguishing specific crack types, indicating limitations in isolating interface delamination independently.

Ray-path results show strong agreement with DIC observations in terms of crack initiation, localisation, enabling direct interpretation along propagation paths. Tomographic results provide a spatial overview of damage distribution and indicate potential for identifying interface disturbances through the dt indicator at early load stages; however, reconstruction limitations and numerical sensitivities reduce reliability in consistently representing damage magnitude and progression.

This paper examines the architectural transformation of Koningin Emmakade 170, a Neo-classical building constructed in 1894 in the Duinoord neighbourhood of The Hague, Netherlands. Through close analysis of original construction drawings held in the Hague Municipal Archives, the research traces four distinct phases of the building's evolution, from a bourgeois townhouse to an informal care institution, a religious convent, and finally secular apartments. The central argument is that each transformation was driven not by isolated design decisions but by broader social and institutional forces operating across the city. The creation of Duinoord as a prestigious residential district for the colonial and professional elite, the rise of religiously organised welfare provision under Dutch pillarization, and the subsequent secularisation of Dutch society from the 1970s onwards are each legible in the building's evolving floor plans, facades, and spatial organisation. Drawing on the concept of the urban palimpsest, the paper argues that Koningin Emmakade 170 functions as a social document in which successive layers of occupation remain visible, even as each new function partially erased or repurposed what came before. The analysis engages critically with this metaphor, acknowledging that the layers are not always sequential or coherent but can be contradictory and overlapping. The paper situates itself at the intersection of micro-scale archival analysis and macro-scale urban history. Ultimately, Koningin Emmakade 170 demonstrates how a single structure can encapsulate the social transformations of a city.

This thesis investigates how energy transitions reshaped the spatial organization of typical Dutch workers' homes between 1900 and 1980. Focusing on the transitions from coal to gas and subsequently to central heating and electrification, the research examines how changes to energy infrastructure influenced the presence, function or disappearance of specific spaces within the home. While previous studies have addressed energy systems, housing policy, and architectural floor plans, the direct impact of energy transition on the Dutch floor plan remains under explored.
A comparative analysis of working-class housing in the Netherlands combined with archival materials from three specific time periods is done in the paper. The analysis is structured around three key categories: energy storage, heating source, and thermal zoning. The findings demonstrate that coal-based systems required significant spatial allocation for storage, usually meant a single heat source and had a strong thermal hierarchy. The introduction of gas reduced storage needs and enabled limited spatial heating flexibility, while central heating fundamentally transformed the floor plan layout by separating heat generation and distribution, eliminating thermal zoning.
This study concludes that energy transitions acted as a primary driver in the evolution of the typical Dutch workers' home floor plan layout, shifting from spatial centralization to open floor plans with uniform and flexible temperature regulation. These historical insights provide a valuable perspective for understanding how current energy transitions may continue to shape residential architecture in the future.

This study investigates whether a prescribed urban colour plan can foster a sense of belonging among residents, using the Regenboogbuurt (Rainbow Neighbourhood) in Almere, the Netherlands, as a case study. Designed with a comprehensive colour scheme to prevent urban monotony, the neighbourhood draws inspiration from German architect Bruno Taut’s colourful social housing projects in Berlin.

The research evaluates the transition from ‘plan’ to ‘place,’ focusing on the interaction between urban guidelines and architectural execution, specifically through Liesbeth van der Pol’s ‘Rooie Donders’. Furthermore, the study combines written documentation about the design with interviews with residents and site visits to reveal the daily lived experience.

Findings suggest that residents subconsciously identify with the neighbourhood’s character, often mirroring its external façade colours in their home interiors. However, the study also identifies a growing threat to the area’s cohesive identity, due to unauthorised individual modifications and a lack of municipal supervision. The thesis concludes that a colour strategy can foster a sense of belonging, when is supported by active community engagement and formal legal protections, such as a protected townscape status.
