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.

Dit project ontwikkelt een wetenschappelijke methode om klinisch relevante nieuwe informatie te extraheren uit patiëntenforum-websites die ervaringen van patiënten bespreken over bv. medicatie, voeding, co-morbiditeiten, genetische factoren enz.

Innovation plays an essential role in firms' competitiveness and long-term success. It varies from different types, ranging from run-of-the-mill innovation that brings incremental changes to existing technologies to radical innovation that breaks from existing trajectories.

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

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…

A common method to solve expensive function evaluation problem is using Bayesian Global Optimization, instead of Evolutionary Algorithms.

Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Elk jaar organiseert eLaw verschillende congressen, symposia, workshops, panels en andere evenementen.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

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…

Technologies that help to enhance our educational environments can be found everywhere.

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

De Faculteit der Wiskunde en Natuurwetenschappen is gevestigd op verschillende locaties in het Bio Science Park Leiden.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Human language is constantly evolving with its linguistic structure being shaped by language users at both individual and population levels. Focusing on the interplay between processes of language acquisition and communicative need in shaping human languages, this thesis introduces a novel computational…

This dissertation advances automated negotiation by developing agents that can learn and adapt across diverse negotiation settings through three increasingly sophisticated approaches: automated algorithm configuration, portfolio-based strategy selection, and end-to-end reinforcement learning with graph…

Het witwassen van de gelden die worden verkregen uit cybercrime vindt in toenemende mate plaats met digitale betalingsmiddelen. In dit onderzoek wordt nagegaan hoe deze gelden worden witgewassen, welke actoren een rol spelen en hoe digitale betalingsmiddelen daarbij worden gebruikt.

This thesis investigates Open-world Continual Learning (OWCL), a learning paradigm designed for intelligent systems operating in non-stationary environments with persistent exposure to unknown data.

This dissertation investigates how the efficiency of Computed Tomography (CT) can be improved for dynamic scientific and industrial applications.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

Traditional biochemical methods for studying organelles require cell disruption, preventing the real-time observation of dynamic intracellular processes.

Effective policy-making requires understanding what truly causes a problem. Only then can policymakers develop targeted interventions that achieve desired outcomes.

Elk jaar organiseert het LIBC in samenwerking met de gemeente Leiden een Publieksdag over hersenonderzoek.

De meest trillingvrije, cryogene ‘scanning tunneling’ microscoop ter wereld maken. Een gedurfde missie, die promovendus Irene Battisti met succes heeft uitgevoerd samen met de Fijn Mechanische Dienst. De nieuwe microscoop kan mogelijk nieuw licht werpen op hoe onconventionele supergeleiding precies…

Aangespoeld plastic onderzoeken of het verzorgen van gewonde wilde dieren: vrijwilligers zijn onmisbaar in het beschermen van de natuur. Toch blijft hun waardevolle kennis nog te vaak onbenut, concludeert promovendus Liselotte Rambonnet.

Een koffer beplakt met stickers van verschillende universiteiten, met hierin een quantumlichtbron. Sinds april 2024 bezoekt deze koffer in Europa wetenschappers die onderzoek doen naar losse fotonen: de kleinst mogelijke hoeveelheid van licht. De koffer, ook wel ‘Q-torch’ genoemd, reist van lab naar…
