Molendijk, Thomas (author)The k-truncated metric dimension of a graph is the minimum number of sensors (a subset of the vertex set) needed to uniquely identify every vertex in the graph based on its distance to the sensors, where the sensors have a measuring range of k. We give an algorithm with the goal that given any tree and any value for the measuring range of the...bachelor thesis 2023

Tong, Mathew (author)According to the Oxford Learner’s Dictionaries, the notion of “space” can be read in several ways, of what is the five general understandings of it would be: outside earth’s atmosphere, empty area, period, freedom, and lastly, where things exist/move. With the speed, amount of information, and technology we are currently facing in the 21st...master thesis 2023

Moradi, M. (author), Chiachío, Juan (author), Zarouchas, D. (author)Composite structures are highly valued for their strength-to-weight ratio, durability, and versatility, making them ideal for a variety of applications, including aerospace, automotive, and infrastructure. However, potential damage scenarios like impact, fatigue, and corrosion can lead to premature failure and pose a threat to safety. This...conference paper 2023

(author)Sand and dust storms (SDS) are a major disruptor in both the source areas where they occur and at distant locations. This critical review aims to address the question of whether mitigation and adaptation measures have been or can be implemented and what is the optimal scale of their implementation to negate the impacts of SDS in Eastern...review 2023

Sterken, Sven (author), Pohl, D. (author)International organisations and global governance studies typically refer to “architecture” as the structures of decision-making, power distribution, or financial flows. This position paper challenges this conventional understanding by delving into its primary meaning—the built environment. It charts ways in which architectural design,...journal article 2023

Bartha, Zsolt (author), Komjáthy, J. (author), Raes, Järvi (author)A k-truncated resolving set of a graph is a subset S⊆V of its vertex set such that the vector (d<sub>k</sub>(s,v))<sub>s∈S</sub> is distinct for each vertex v∈V where d<sub>k</sub>(x,y)=min{d(x,y),k+1} is the graph distance truncated at k+1. We think of elements of a k-truncated resolving set as sensors that can measure up to distance k. The...journal article 2023

Toshniwal, D. (author), Villamizar, Nelly (author)Multivariate piecewise polynomial functions (or splines) on polyhedral complexes have been extensively studied over the past decades and find applications in diverse areas of applied mathematics including numerical analysis, approximation theory, and computer aided geometric design. In this paper we address various challenges arising in the...journal article 2023

Kodak, B.L. (author), Vardar, Y. (author)The ever-emerging mobile market induced a blooming interest in stylus-based interactions. Most state-of-the-art styluses either provide no haptic feedback or only deliver one type of sensation, such as vibration or skin stretch. Improving these devices with display abilities of a palette of tactile feels can pave the way for rendering...journal article 2023

CHENG, ZHIMIN (author)A wide range of practical problems involve computing multi-dimensional integrations. However, in most cases, it is hard to find analytical solutions to these multi-dimensional integrations. Their numerical solutions always suffer from the `curse of dimension', which means the computational complexity grows exponentially with respect to the...master thesis 2022

Datema, Tobias (author)In this thesis, we consider the threshold metric dimension problem of graphs, related to and motivated by source detection.<br/>We construct a graph G = (V,E) for a given set of sensors of size m: {s1, s2, ..., sm} and a range k > 0. We want that each node v ∈ V has a unique combination of distances (dk (s1, v),dk (s2, v), ...,dk (sm, v)),...bachelor thesis 2022

Tahur, Nishad (author)Color information has been shown to provide useful information during image classification. Yet current popular deep convolutional neural networks use 2-dimensional convolutional layers. The first 2-dimensional convolutional layer in the network combines the color channels of the input images, which produces feature maps per channel with only...master thesis 2022

Klazinga, Rembrandt (author)Autoencoders seek to encode their input into a bottleneck of latent neurons, and then decode it to reconstruct the input. However, if the input data has an intrinsic dimension (ID) smaller than the number of latent neurons in the bottleneck, this encoding becomes redundant. <br/>In this paper, we study using the Early-Bird (EB) technique, a...master thesis 2022

Lantsoght, E.O.L. (author)The doctoral defense is an important step towards obtaining the doctoral degree, and preparation is necessary. In this work, I explore the relation between the way in which a doctoral candidate prepares for the defense and two important aspects of the defense: the outcome of the defense, and the student perception during and after the defense. I...journal article 2022

(author)Natural sediment flocs are fragile and highly heterogeneous aggregates of biogenic and minerogenic material typically with high porosity and low density. In aquatic environments dominated by fine, cohesive or mixed sediments they can dominate suspended sediment flux. Consequently, monitoring and modelling the behaviour, transport and...journal article 2022

A Two-Step Feature Extraction Algorithm: Application to deep learning for point cloud classificationNurunnabi, A. (author), Teferle, F. N. (author), Laefer, D. F. (author), Lindenbergh, R.C. (author), Hunegnaw, A. (author)Most deep learning (DL) methods that are not end-to-end use several multi-scale and multi-type hand-crafted features that make the network challenging, more computationally intensive and vulnerable to overfitting. Furthermore, reliance on empirically-based feature dimensionality reduction may lead to misclassification. In contrast, efficient...journal article 2022
