Abrupt Climate Change and Cultural Transformation

Using formal methods, we rigorously validate and verify functionality and security properties of essential Internet protocols. In this project, we unambiguously specify Internet protocols (i.e. IP, TCP, UDP, BGP, DNS) using Reowolf's Protocol Description Language (PDL).

How citizens and professionals are the key to successful collaboration in the delivery of public services. How do individual characteristics of citizens and professionals influence citizen-professional collaboration in the co-production of public services?

In this research we have studied how teaching graphing formulas by hand (i.e. sketching a graph of a formula) could promote grade 11- and 12-students’ symbol sense.

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

The Europa Institute of Leiden University is one of the oldest academic institutes specialised in the law of the European Union and the European Convention on Human Rights; it was established in 1957, the same year as the European Economic Community itself.

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

Empirical and experimental research focusing on literary, legal, medical and audiovisual translation.

The reintegration of high profile ex-offenders frequently receives great political and public attention. While this attention, more often than not in the form of negative sentiments, may be understandable from a moral perspective, it raises several important questions: how do such offenders reintegrate…

The starting hypothesis of the project is that secrecy is not always inimical to democratic governance as conventional wisdom has it.

In our culture, vocal harmonics function as independent musical elements since only a few decades. Thresholds of the audible explores the changing relationship between singers, listeners and harmonics.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.
