Ditzel, M. (author), Kester, L.J.H.M. (author), van den Broek, S.P. (author), van Rijn, M. (author)Multilevel fusion systems need provisions to optimally schedule scarce processing and communication resources. To this end, we explore the idea of using utility-based metrics to optimize the run-time operation of a computation and communication constrained multilevel system, including automatic decision support measures such as course of action...conference paper 2013

Knoop, V. (author), van Lint, J. (author), Vries, J. (author), Kester, L.J.H.M. (author), Passchier, I. (author)Congestion is a major problem in large, urbanized areas. Intelligent transport solutions aim to reduce this problem. In general, traffic is monitored with the use of sensors, the resulting data are processed, a traffic state is estimated, and a control measure is computed and implemented. The availability and the quality of the data and the...article 2013

van Foeken, E. (author), Kester, L.J.H.M. (author)To reach their goals in the most effective way a team of entities needs to have a high situation awareness. In addition, the awareness needs to be shared among the entities and preferably identical in order to coordinate their actions. Unfortunately, optimal identical shared awareness is often not possible due to limited communication...conference paper 2012

van Willigen, W.H. (author), Schut, M.C. (author), Kester, L.J.H.M. (author)In the development of Cooperative Adaptive Cruise Control (CACC) systems, spacing policies are primarily developed for optimisation of string stability and traffic stability. However, the safety issue is hardly taken into account. Uncertainty in the communication network and sensor information makes deciding upon a safe minimal headway a non...conference paper 2011

van Willigen, W.H. (author), Schut, M.C. (author), Kester, L.J.H.M. (author)This paper is concerned with safety in (cooperative) adaptive cruise control systems. In these systems, the speed of the cars is maintained automatically, based on the preferred speed of the driver and the speed of the preceding car. Technologies that are used in these systems, such as radar and radio communication, introduce many factors of...conference paper 2011

van Willigen, W.H. (author), Schut, M.C. (author), Eiben, A.E. (author), Kester, L.J.H.M. (author)In this paper, we propose a technique for optimisation and online adaptation of search paths of unmanned aerial vehicles (UAVs) in search-and-identify missions. In these missions, a UAV has the objective to search for targets and to identify those. We extend earlier work that was restricted to offline generation of search paths by enabling the...conference paper 2011

Ditzel, M. (author), Kester, L.J.H.M. (author), van den Broek, S.P. (author)Currently, there is no clear-cut approach or design methodology available for designing distributed adaptive observation systems, partly due to the necessity to combine elements and approaches from several technological and scientific communities. Recently, an effort was made addressing this issue in an integrated manner, resulting in the...conference paper 2011

Bakker, B. (author), Whiteson, S. (author), Kester, L.J.H.M. (author), Groen, F.C.A. (author), TNO Defensie en Veiligheid (author)Traffic light control is one of the main means of controlling road traffic. Improving traffic control is important because it can lead to higher traffic throughput and reduced traffic congestion. This chapter describes multiagent reinforcement learning techniques for automatic optimization of traffic light controllers. Such techniques are...bookPart 2010

van Foeken, E. (author), Kester, L.J.H.M. (author), Bergmans, J. (author), TNO Defensie en Veiligheid (author)Networked systems that gather sensor data in order to re act to phenomena in their surroundings are faced with a growing need for adaptive behavior to operate in dynamically changing environments. In designing such a networked system we decompose the data processing chain in distinct functions. These functional components interact by requesting...conference paper 2009

TNO Defensie en Veiligheid (author), van Foeken, E. (author), Kester, L.J.H.M. (author), van Iersel, M. (author)Sensor systems need to be more adaptive to perform well in dynamically changing environments. Common awareness in sensor systems enables distributed agents to perform coordinated actions and reason about other agents. In addition, physical distribution of the agents in the network prevent a single point of failure and provides distributed...conference paper 2009
