The aim of this paper is to test and analyse a novel technique for image reconstruction in positron emission tomography, which is based on (total variation) regularisation on both the image space and the projection space. We formulate our variational problem considering both total variation penalty terms on the image and on an idealised sinogram to be(More)
The problem of path following and formation control for underactuated 3-degrees-of-freedom surface vessels in the presence of unknown ocean currents is considered. The proposed controllers make the vessels asymptotically constitute a desired formation that follows a given straight-line path with a desired speed profile. This control goal is achieved in the(More)
We present the results of the application of model predictive control (MPC) to a micro-simulation model with a scenario where shock waves are present, and a microsimulation model functions as a substitute for the real-world traffic system. Shock waves emerge in most cases from traffic jams at bottlenecks, propagate upstream on the freeway, and can remain(More)
Micro aerial vehicles may build a collective of smart sensor objects cooperating in civilian missions such as search and rescue, farmland monitoring, or surveillance. Wireless connectivity is a prerequisite for transferring images and other sensor data to the ground. Though aerial vehicles may set up a multi-hop wireless network on their own, vehicle(More)
Traffic jams are an economic and environmental problem in many countries. When traffic demand exceeds the freeway capacity, shock waves can be caused by small disturbances in the traffic flow. Since it is not always desirable or feasible to add more lanes on freeways to overcome capacity problems, alternative methods have been developed to reduce and to(More)
The aim of this paper is to track transmigrating leukocytes via TGV flow estimation. Recent results have shown the advantages of the nonlinear and higher order terms of TGV regularizers, especially in static models for denoising and medical reconstruction. We present TGV-based models for flow estimation with the goal to get an exact recovery of simple(More)
Hundreds of tons of depleted uranium (DU) ammunition were used in previous armed conflicts in Iraq, Bosnia and Herzegovina, and Serbia/Kosovo. The majority (>90%) of DU penetrators miss their target and, if left in the environment, corrode in these postconflict zones. Thus, the best way to understand the fate of bulk DU material in the environment is to(More)
