On metrics and models for multiplex networks
In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

Complex Patterns in Streams
The goal of the project is the development of stream mining techniques for complex patterns such as graphs. We will try to extend the existing state-of-the-art techniques into two, orthogonal directions: on the one hand, the mining of more complex patterns in streams, such as sequential patterns and…

Social network and radical innovation: evidence from the U.S. pharmaceutical and biotechnology industry
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.

Network analysis methods for smart inspection in the transport domain
Transport inspectorates are looking for novel methods to identify dangerous behavior, ultimately to reduce risks associated to the movements of people and goods. We explore a data-driven approach to arrive at smart inspections of vehicles.

Complex multiplication constructions of abelian extensions of quartic fields
In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

information and variational Bayes in high dimensional statistical network inference
This thesis develops statistical methods for the analysis of high dimensional data: high dimensional networks reconstruction (Chapters 1-4), incorporation of prior information in networks reconstruction (Chapters 2-4), incorporation of prior knowledge in genetic association studies (Chapter 3).

How Jihadist Networks Operate
De recente terroristische aanslagen in Europa zijn vermoedelijk niet alleen acties van individuen, maar acties gefaciliteerd door grotere jihadistische netwerken. Maar hoe opereren dit soort netwerken? Door inzicht te krijgen in hun modus operandi kunnen terroristische dreigingen worden voorkomen.

Wireless Random-Access Networks and Spectra of Random Graph
This thesis is divided into two parts. In Part I we study metastability properties of queue-based random-access protocols for wireless networks. The network is modeledas a bipartite graph whose edges represent interference constraints. In Part II we study spectra of inhomogeneous Erdős-Rényi random…

Systematics and biogeography of the rattan Calamus javensis complex (Arecaceae, Calamoideae) in Malesia
Calamus javensis is polymorphic. Morphometry and molecular approach resulted in all names used in the complex are regarded as synonyms of C. javensis except C. tenompokensis, which is retained as a distinct species. One variety is here recognized, C. javensis var. polyphyllus (including C. acuminatu…
