This paper explores new methods to visualize and fuse multi-2D bioluminescence imaging (BLI) data with structural imaging modalities such as micro CT and MR. A geometric, back-projection-based 3D reconstruction for superficial lesions from multi-2D BLI data is presented, enabling a coarse estimate of the 3D source envelopes from the multi-2D BLI...

Seagrasses are a valuable but threatened part of coastal systems. To aid restoration attempts, a model has been made to study the effect of such flexible aquatic vegetation on flow and sediment transport. Because this model needs to be tested against field results, a field experiment was undertaken around an eelgrass meadow in Dinard, France....

Worldwide, aquatic vegetation is important for the physical and ecological condition of coastal areas. Unfortunately, this vegetation (e.g. seagrasses) is also under pressure due to human activities. Protection and restoration are cumbersome, particularly because the complex relations between vegetation and its environment are not yet well...

In many areas around the world, there is a large interest in the protection and restoration of aquatic vegetation, like eelgrass (Zostera marina), but little is known about the interaction of such vegetation with its environment. To improve this knowledge, a model has been developed that simulates this interaction between highly flexible...

Electro-osmosis consolidation is an innovative and effective ground improvement method for soft clays. But electro-osmosis is also a very complicated process, as the mechanical behaviour, and hydraulic and electrical properties of the soil are changing rapidly during the treatment process; this makes electroosmosis hard to describe and simulate....

By changing flow patterns and sediment transport, aquatic vegetation can affect the development of estuarine bed topography. Besides, since the sediment transport also determines the amount of light available for photosynthetic growth, the presence of vegetation can also affect its own development. This selfsupporting interaction should be taken...

In this paper, we propose open machine learning models that can provide airport delay predictions in a network with an error of around or less than five minutes. Due to the complexity of different components of air traffic networks, traditional flight performance model-based predictions fall short when dealing with numerous flights and often are...

All first-year students at Delft University of Technology (TU Delft) are required to take mathematics courses, but their motivation to participate in these courses is generally lower than their motivation for courses that belong to their main field of study. These lower levels of commitment often lead to lower results and weaker understanding of...

Railway systems occasionally get into a state of out-of-control, meaning that there is barely any train is running, even though the required resources (infrastructure, rolling stock and crew) are available. These situations can either be caused by large disruptions or unexpected propagation and accumulation of delays. Because of the large number...

An instrumented model pile has been realized to study the displacement pile installation effects in sand in physical model tests. The system includes a model pile, instrumented with axial and horizontal contact stress sensors, and a corresponding calibration apparatus. The development of the instrumented model pile, including numerical analysis...

1.1 Background To educate future competent engineers, it is crucial to adopt teaching and learning approaches that support students in dealing with highly complex problems [1]. One strategy is to enhance service mathematics in higher engineering education by shifting from outcome-centered to competence-centered approaches [2]. This strategy...

The Sustainable Development Goals (SDGs), comprising of 17 Global Goals, serve as a global framework for addressing various facets of sustainable development. Several of these goals emphasize the crucial role of land management and equitable land distribution in achieving sustainable development objectives. ISO 19152, known as the Land...

The importance of physico-chemical processes at the particle scale for the engineering scale behaviour of fine-grained geomaterials is undisputed. Yet, despite great advances in the discipline, experimental evidence that fully resolves the clay micromechanics i.e. linking the evolving microstructure and interparticle actions under loading, is...

The use of Living Labs is a promising approach to develop and test sustainable system innovations. A Living Lab approach that is yet to be discussed in literature, is that of a Festival Living Lab (FLL). Festivals can be considered as temporary mini societies with systemic sustainability challenges regarding water, energy, housing, logistics,...

A number of computer vision deep regression approaches report improved results when adding a classification loss to the regression loss. Here, we explore why this is useful in practice and when it is beneficial. To do so, we start from precisely controlled dataset variations and data samplings and find that the effect of adding a classification...

Activity progress prediction aims to estimate what percentage of an activity has been completed. Currently this is done with machine learning approaches, trained and evaluated on complicated and realistic video datasets. The videos in these datasets vary drastically in length and appearance. And some of the activities have unanticipated...

Intravascular optical coherence tomography (IVOCT) is an intravascular imaging modality which enables the visualization arterial structures at the micro-structural level. The interpretations of these structures is mainly on the basis of relative image intensities. However, even for homogeneous tissue light intensities can differ. In this study...
