This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

Wiskundige Oliver Nagy kan zich nog levendig herinneren dat hij voor het eerst leerde over ‘random walks’. ‘De docent liet ons denken aan een groep dronken studenten die door de straten dwaalden. Bij elk kruispunt draaien ze één van hen in de rondte en gaan ze in de richting waar diegene tot stilstand…

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

This dissertation presents four separate chapters, all striving towards the same goal: to understand dynamic phenomena occurring in dynamic networks and to explore the emergence of equilibrium in a broad sense.

This dissertation consists of two parts, with the common theme

Volwassenen en kinderen kijken op totaal verschillende manieren naar kunst, ontdekte cognitief psycholoog Francesco Walker in het Van Gogh Museum in Amsterdam. 'In recent onderzoek in het Rijksmuseum in Amsterdam heb ik eye-tracking technologie gebruikt.' Walker vertelt over zijn onderzoek op mediaplatform…

Principles of Environmental Sciences provides a comprehensive picture of the principles, concepts and methods that are applicable to problems originating from the interaction between the living and non-living environment and mankind. Both the analysis of such problems and the way solutions to environmental…

This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

De afdeling richt zich op het verbeteren van het wetenschappelijk begrip in de relatie tussen mens en natuur. Hoe beïnvloedt menselijk handelen (via bijvoorbeeld klimaatverandering, landgebruiksverandering en de emissie van mogelijk toxische verbindingen) de natuur in het algemeen en de biodiversiteit…

Van 2 t/m 6 juni 2014 heeft Prof. dr. Frank den Hollander 2 voordrachten verzorgd tijdens de workshop ‘Recent Models in Random Media’ op het Centre International de Rencontres Mathematiques in Marseille (CIRM), een instituut dat gedurende het hele jaar workshops voor wiskundigen organiseert.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

Metal production is not only energy-intensive and a major source of greenhouse gas (GHG) emissions, but is also associated with other impacts affecting human health and ecosystems.

Hoe bestudeer je de groei van micro-organismen, de verspreiding van epidemieën of de genezing van wonden, zonder daadwerkelijk experimenten uit te voeren? Daoyi Wang, promovendus aan het Mathematisch Instituut, werkte aan een specifiek wiskundig model dat de groei van micro-organismen en vele andere…

IoT technology poses serval opportunities to supply chains. This thesis employs grey correlation and forecasting models, system dynamics, agent-based modeling, and ex-ante LCA to investigate and quantify the opportunities and risks of IoT-enabled sustainable supply chain operations from both industrial…

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).
