The Formation of Migrant Networks This paper provides the first direct evidence on the determinants of link formation among immigrants in the host society. We use a purposely-designed survey on a representative sample of Sri Lankan immigrants living in Milan to study how migrants form social links among them and the extent to which this network provides them with material support along three di...

This paper gives a general overview of the challenges that arise in using narrow-band signals, such as GSM, for localisation based on the time properties of the signal. Specifically, synchronisation and retrieving of time information are addressed. We pursue two contributions, namely, analysis of achievable synchronisation precision and processing of narrowband signals that can enable localizat...

Recent research in queuing focuses more on the impacts of heavy-tailed service times, neglecting the fact that stochastic inter-arrival times are often heavy-tailed as well. We investigate the impacts of heavy-tailed gamma inter-arrival time distributions on the waiting-time distribution of a GI/G/2 queue, and simulate the tail properties of waiting-time distribution using real data.

We study a system of two queues in tandem with finite buffers, Poisson arrivals to the first station, and exponentially distributed service times at both stations. Losses are incurred either when a customer is rejected at the time of arrival to the first station or when the second station is full at the time of service completion at the first station. The objective is to determine the optimal a...
