Optimal control of a parabolic PDE system arising in plasma transport via diffusivity-interior-boundary actuation
— In this paper, we study an optimal control problem arising in plasma transport which is governed by a singularly perturbed system. Time-scale separation allows us to focus on a...

Nonmaterialized Motion Information in Transport Networks
The traditional way of representing motion in 3D space-time uses a trajectory, i.e. a sequence of (x,y,t) points. Such a trajectory may be produced by periodic sampling of a Global...

HxH: a hop-by-hop transport protocol for multi-hop wireless networks
TCP can perform poorly in multi-hop wireless networks due to problems that arise with contention and mobility. Endto-end protocols are at an inherent disadvantage in trying to sol...

IMproved results for route planning in stochastic transportation
In the bus network problem, the goal is to generate a plan for getting from point X to point Y within a city using buses in the smallest expected time. Because bus arrival times a...

Scheduling Locomotives and Car Transfers in Freight Transport
Abstract. We present a new model for a strategic locomotive scheduling problem arising at the Deutsche Bahn AG. The model is based on a multi-commodity min-cost flow formulation th...
