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.

This dissertation focuses on developing new mathematical and statistical methods to properly represent time-varying covariates and model them within the context of time-to-event analysis.

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

In this dissertation, we study partition-based models that can be used both for interpretable predictive modeling and for understanding data via interpretable patterns.

Op 31 maart 2017 organiseren de Université de Liège (Liège Competition and Innovation Institute) en de KU Leuven, in samenwerking met de Vlaamse overheid, een conferentie over staatssteun.

Op 9 maart vond de allereerste editie van de PhD day plaats aan de KU Leuven, een initiatief van de VSR en ELS Academy. De PhD day ging vooraf aan het VSR jaarcongres van 10 en 11 maart.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

The main subject of this thesis is the design and synthesis of paramagnetic molecules for protein studies with NMR and EPR spectroscopy.

The global agri-food system plays a critical role in food security and environmental issues.

Big Science, commonly defined as conventional science made big in three dimensions, namely organizations, machines, and politics, brings a plethora of different stakeholders together, often for a long period of time. This includes policymakers, scientists, (scientific) managers as well as local “host”…

In dit artikel bestuderen de auteurs hoe individuele variabelen en variabelen op landelijk niveau op elkaar inwerken bij het beïnvloeden van politieke genderattitudes in Europa.

Wat is het effect op het milieu van het 2016-verbod op gratis plastic tasjes? Industrieel ecoloog Stefano Cucurachi heeft een subsidie ontvangen van €75.000 van het LUF-SVM Projectsubsidie Fonds* om deze vraag te beantwoorden.

To conclude, this thesis provides valuable methodological insights to address data gaps and improve environmental impact assessments within the circular economy, with a particular focus on product reuse and sharing practices. Through empirical analysis and innovative approaches, it aims to support informed…

Calamus javensis is polymorphic. Morphometry and molecular approach resulted in all names used in the complex are regarded as synonyms of C. javensis except C. tenompokensis, which is retained as a distinct species. One variety is here recognized, C. javensis var. polyphyllus (including C. acuminatu…

This thesis involves three topics: benchmarking discrete optimization algorithms, empirical analyses of evolutionary computation, and automatic algorithm configuration.

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

Wij richten ons op natuurlijke producten van onderzoek, de traditionele geneeskunde, etnobotanie en fytochemie.

Hoe kunnen we onze maatschappij zo inrichten dat de wereld leefbaar blijft voor onszelf en al het andere leven om ons heen? Aan dat vraagstuk werken Leidse wetenschappers samen vanuit allerlei disciplines, van biologie tot datawetenschap en van milieueconomie tot archeologie.

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…

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

Politicologen Rebekah Tromble en Michael Meffert (Universiteit Leiden) analyseren waarom sommige media frames aanhouden, terwijl andere frames snel in de vergetelheid geraken. Zij ontwikkelen een methode die is ontleend aan event-history. De casus die Tromble en Meffert bekijken, is de verslaglegging…

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Op 5 september 2019 verdedigde Jennifer Doekhie haar proefschrift 'Dimensions of desistance: A qualitative longitudinal analysis of different dimensions of the desistance process among long-term prisoners in the Netherlands'. Het promotieonderzoek is begeleid door promotor prof.dr. P. Nieuwbeerta.
