Continuous approximation of collective system behaviour: A tutorial

L Bortolussi, J Hillston, D Latella, M Massink - Performance Evaluation, 2013 - Elsevier
In this paper we present an overview of the field of deterministic approximation of Markov
processes, both in discrete and continuous times. We will discuss mean field approximation …

Incentives and redistribution in homogeneous bike-sharing systems with stations of finite capacity

C Fricker, N Gast - Euro journal on transportation and logistics, 2016 - Springer
Bike-sharing systems are becoming important for urban transportation. In these systems,
users arrive at a station, pick up a bike, use it for a while, and then return it to another station …

MPTCP is not Pareto-optimal: Performance issues and a possible solution

R Khalili, N Gast, M Popovic… - IEEE/ACM Transactions …, 2013 - ieeexplore.ieee.org

Optimal generation and storage scheduling in the presence of renewable forecast uncertainties

N Gast, DC Tomozei… - IEEE Transactions on …, 2014 - ieeexplore.ieee.org
Renewable energy sources, such as wind, are characterized by non-dispatchability, high
volatility, and non-perfect forecasts. These undesirable features can lead to energy loss …
