For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

This thesis manuscript explores the use of video games as tools for conceptual exploration and academic research.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

The following report discusses a survey on the topic of the Sustainable Development Goals that was distributed among researchers at Leiden University in the month of November 2021.

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

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

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

De onderzoeksgroep Governance of Crises bestudeert fenomenen, dynamieken en actoren die te maken hebben met crisisgovernance. Het Crisis Research Center (CRC) van de Universiteit Leiden maakt deel uit van deze onderzoeksgroep.

De programmagroep Onderzoeksmethoden en statistiek biedt ondersteuning aan onderzoekers uit veel verschillende onderzoeksprojecten binnen het instituut Pedagogische Wetenschappen.

De Faculteit der Sociale Wetenschappen combineert hooggekwalificeerd onderzoek en uitstekend onderwijs in de disciplines culturele antropologie, pedagogische wetenschappen, politieke wetenschap, psychologie, wetenschaps- en techniekstudies, evenals in multidisciplinaire benaderingen.

In this thesis we investigate cosmology and the large scale structure of the Universe using cosmological simulations.

Leiden My Way is een co-curriculair persoonlijk ontwikkelprogramma uitgevoerd aan de Faculteit der Sociale Wetenschappen.

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

Anticipatie op de uitdagingen en voordelen die AI-ondersteunde beoordelingen met zich meebrengen voor de relatie tussen studenten en docenten, de menselijke, evenals sociaal-economische kosten en kansen die zij voor universiteiten creëren.

Een van de kernthema’s in het aanbod van CPL is ‘’internationale betrekkingen’.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

Jaarlijks organiseert het Alumnibureau van de Universiteit Leiden een aantal masterclasses. Deze masterclasses zijn exclusief toegankelijk voor Leidse alumni.

Hoe stimuleer je dat de nieuwe uitgangspunten van het curriculum Geneeskunde verder vorm krijgen in het onderwijs?

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

The different kinds of cultural perspectives on health and disease of the participants are related to their knowledge, beliefs, values and practices manifested in various forms of lifestyle in Indonesia. The cultural diversity of the population is also related to differences in health behaviour.

Het kwantificeren van lichamelijke activiteit (met behulp van versnellingsmeters) en het combineren van de frequentie en intensiteit van activiteiten met gezondheidsgegevens (hersen-MRI, traditionele klinische parameters en metabolomics) is van het grootste belang om mobiliteit en gezondheid bij oudere…
