Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

Goed werkgeverschap is net als goed werknemerschap een open norm. Daarmee is het onduidelijk en onzeker waar werkgevers zich op dienen te richten en welke rechten (en plichten) werknemers hebben in dat verband. De doelstelling van dit onderzoek is om invulling te geven aan de norm goed werkgeverschap…

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

How does governing work today, and how does society handle pressing challenges in ways that are democratic, effective, fair, peaceful, and sustainable?

Op 28 juni 2018 verdedigde Qiuyin Hu zijn proefschrift 'Regulating Working Conditions in Times of Globalization'. Het promotieonderzoek is begeleid door promotoren prof.dr. G.J.J. Heerma van Voss en prof. dr. B. Barentsen.

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

Investigating the contribution of interpreters, informants, hunters and guides in the making of colonial scientific knowledge.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

De onderzoeksgroep Organizational & Entrepreneurial Behavior onderzoekt het gedrag van individuen en groepen die in organisaties werken, organisaties starten, of organisaties leiden, met als doel om organisatorische praktijken te informeren. Door zich te concentreren op het gedrag van (groepen) werknemers,…

Patients share valuable advice and experiences with their peers in online patient discussion groups.

In this top-rated course, you will learn how the European Union prepares and decides on policy, and how policy is transferred to member states and implemented by various authorities. It discusses the challenges of the European multi-level governance structure and the main causes of policy failure or…

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

This dissertation presents new cryptographic protocols, which can be divided into two families.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

This initiative is intended to support generative research collaborations between and among scholars located in different geographical regions who wish to pursue focused, joint projects in any area of the study of religion.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

Developing robust algorithms and theory for establishing cause-effect relationships from observational data that scale up to large data sets

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.

Wat doe je als je iets te weten wilt komen? Tegenwoordig gebruikt men voornamelijk het internet om informatie te verkrijgen. Een lezer moet deze informatie vaak uit meerdere bronnen halen en die bronnen met elkaar in verband brengen, om zo een compleet plaatje te vormen van het onderwerp. Soms is de…

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.
