Random walks: als een groep dronken studenten door de straten
Wiskundige Oliver Nagy kan zich nog levendig herinneren dat hij voor het eerst leerde over ‘random walks’. ‘De docent liet ons denken aan een groep dronken studenten die door de straten dwaalden. Bij elk kruispunt draaien ze één van hen in de rondte en gaan ze in de richting waar diegene tot stilstand…

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…

The integration of meta-analysis and classification & regression trees: meta-CART
In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).
