Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

In this thesis, mathematical modeling and simulation was applied as a tool to inform quantitative decision making in oncology drug discovery and development.

Wat is quantum nou eigenlijk? Tja, probeer dat maar eens in begrijpelijke taal uit te leggen. In diverse regionale kranten doet wiskundige Peter Bruin een poging. ‘Om quantum te begrijpen, moet je tegen je intuïtie in denken. Daar is ons brein niet voor gemaakt.’

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

This thesis covers various applications of topology in condensed matter physics and quantum information.

A convolutional neural network (CNN) is a biologically inspired algorithm, highly capable at processing images and videos.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

Welke rol speelt de vindbaarheid van verantwoordingsinformatie in het gebruik hiervan door Kamerleden? Dr. Valérie Pattyn, Prof. Dr. Caelesta Braun en Menno de Groot van het Instituut Bestuurskunde onderzochten samen met KWINK groep en de Nederlandse School voor Openbaar Bestuur of het meesturen van…

Het Quantum Delta NL-programma, waaraan de Universiteit Leiden deelneemt, krijgt 615 miljoen euro uit het Nationaal Groeifonds om Nederland te ontwikkelen tot een koploper in quantumtechnologie. Dit werd vandaag bekend gemaakt bij de presentatie van de winnende voorstellen in Den Haag.

Dimiter Toshkov, UHD, Brendan Carroll, UD, en Kutsal Yesilkagit, Professor International Governance, van de Universiteit Leiden schreven een artikel voor de Washington Post over de Europese overheden die snel handelden in tijden van pandemie. En dit zijn niet de overheden die je zou verwachten.

LIACS is a partner in the EU Erasmus+ Curriculum Development for the Asian education system. The knowledge available in the field of Data Science and Artificial Intelligence education will be shared and adapted for the Asian market.

Via een 6 tal publicaties, met bijdragen van Joanne van der Leun, Jelmer Brouwer, Tim Dekkers en Maartje van der Woude, wordt er tussen 7 – 18 maart op het Border Criminologies Blog reeds een kijkje in de resultaten van het onderzoeksproject'“Decision-making in Dutch Borderlands” gegeven.

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

Het Instituut Politieke Wetenschap heeft een zeer divers onderzoeksprogramma. Dit programma dient twee doelen: het bevorderen van de eenheid van het Instituut als een intellectuele gemeenschap van sociale wetenschappers en politicologen en om collega’s met overlappende interessegebieden in staat te…

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

Uncertainty and noise are frequently-encountered obstacles in real-world applications of numerical optimization. The practice of optimization that deals with uncertainties and noise is commonly referred to as robust optimization.

This thesis is is made of three parts. The first part describes a generalization of the Chabauty's method, that can be used to determine the rational points of a curve such that s+g>r+1, where g is the genusof the curve, r is the rank of the Mordell-Weil group of the jacobian of the curve and s is…

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

The unit residue group, to which the present thesis is devoted, is defined using the norm-residue symbol, which Hilbert introduced into algebraic number theory in 1897.
