This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

It’s starting to become a real Dies Natalis tradition: on 8 February professors from Leiden University teach a class at primary schools in the region. This introduces children to academia and teaches them more about conducting research. ‘Had you expected me to be a woman?’

Covid year 2021 might have felt somewhat less strange than the year before, but the virus still left its mark on University life and our students and staff. Fortunately there was also room for research, visiting dignitaries and in-person classes. And our social media accounts weren’t only about covid…

Universiteit Leiden en Unicef werken al 10 jaar samen om kennis over kinderrechten uit te breiden en te verspreiden. Ze verlengen deze samenwerking.

Leiden University is awarding an honorary doctorate to virologist Marc van Ranst. Van Ranst has been one of the main advisers of the Belgian government during the Covid pandemic. German Arabist Beatrice Gründler will also receive an honorary doctorate for her work in the field of Oriental Manuscript…

Leiden University consists of seven faculties, each managed by a dean.

Over the centuries painters and photographers have depicted students at study in Leiden. An exhibition at the Hortus botanicus reveals the similarities and differences in 450 years of student life.

Video conferencing from your sitting room and algorithms on social media that know your interests: new technology is an increasingly integral part of our lives. At the same time there is a growing call to protect our privacy, and this is causing friction, at the University too. In part because of the…

The energy transition ranks high on the European policy agenda, but what does it take to get there? René Kleijn researches how we can extract, use and reuse raw materials in a responsible way. Since 1 March, he has been appointed professor of Resilient resource supply.

The Municipality of The Hague called on researchers to come up with a proposal for an innovative research project on problems big cities face such as energy transition. Four of the five projects that have been granted funding come from researchers from Leiden University.

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

What is the size and composition of the Dutch urban mine? How will the urban mine develop over time, and how can it be used as a source of materials as part of a circular economy?

The Faculty of Science is located at the Leiden Bio Science Park. It was founded more than two centuries ago and currently, more than 8000 people are working and studying at the eight institutes.

With the advent of multicore processors and data centers, computer hardware has become increasingly parallel, allowing one to run multiple pieces of software at the same time on different machines. Coordination of these pieces is best expressed in a coordination language as an explicit interaction protocol…

This thesis addresses the problem of designing performance and energy efficient embedded streaming systems, that is, systems which process a stream of input data coming from the environment and generate a stream of output data going into the environment.

We strive to address the challenge of constructing a modeling language to write software which can take advantage of recent hardware developments (multicore, cloud) without compromising in its abstraction levels.
