16. Demand responsive resource management for cellular networks : link asymmetry, pricing and multihopping
Abstract : Economic affordability of services and infrastructures has rapidly become one of the key issues in the evaluation and design of wireless access systems. The provisioning of high data rates, at an ``affordable'' price, constitutes a serious challenge to the structure and management of current and future wireless networks. READ MORE

17. On Risk Prediction
Abstract : This thesis comprises four papers concerning risk prediction. Paper [I] suggests a nonlinear and multivariate time series model framework that enables the study of simultaneity in returns and in volatilities, as well as asymmetric effects arising from shocks. READ MORE

18. The Human Right to Leave: But Whereto?
Abstract : While all persons — with a few exceptions — are allowed to leave any country regardless of nationality, not all persons are allowed to enter any country of their choosing; and only citizens enjoy, in principle, the right to enter their country of nationality, which most often, and by necessity, is a restricted number of countries, since some of them prohibit multiple nationality. One claim that is frequently made in contemporary migration-related literature, and that much migration-related philosophical debate presupposes in one way or another, yet remains unexplored, is the claim that the right to leave a state – enshrined in the Universal Declaration of Human Rights of 1948 – does not entail a right to enter another state.

20. Noise Convolution Models: Fluids in Stochastic Motion, Non-Gaussian Tempo-Spatial Fields, and a Notion of Tilting
Abstract : The primary topic of this thesis is a class of tempo-spatial models which are rather flexible in a distributional sense. They prove quite successful in modeling (temporal) dependence structures and go beyond the limitation of Gaussian models, thus allowing for heavy tails and skewness. READ MORE
