Representing the Virtual: Using AAS to Expose Digital Assets

The Industry 4.0 Asset Administration Shell provides a standardized mechanism for collaboration between digital systems in the factory. Digital data within factories is typically stored in databases, we explore the requirements of providing an AAS as an interface to the data contained within the aforementioned databases. Based on these...

Talking Trucks: Decentralized Collaborative Multi-Agent Order Scheduling for Self-Organizing Logistics

Logistics planning is a complex optimization problem involving multiple decision makers. Automated scheduling systems offer support to human planners; however state-of-the-art approaches often employ a centralized control paradigm. While these approaches have shown great value, their application is hindered in dynamic settings with no central...

Letting digital twins run the show. Exploring possibilities of letting vehicles plan and organise transportation themselves

In this paper we present a way to organize logistics entirely by decentral decision-making. This is achieved by implementing a degree of intelligence in the digital twins of a fleet of trucks and subsequently fully yielding autonomy from planners to the fleet

CoCoA: A non-iterative approach to a local search (A)DCOP Solver

We propose a novel incomplete cooperative algorithm for distributed constraint optimization problems (DCOPs) denoted as Cooperative Constraint Approximation (CoCoA). The key strategy of the algorithm is to use a semi-greedy approach in which knowledge is distributed amongst neighboring agents, and assigning a value only once instead of an...

Self Adaptive Safe Provisioning of Wireless Power Using DCOPs

Wireless Power Transfer (WPT) technologies aim at getting rid of cables used by consumer devices for energy provision. As long distance WPT is becoming mature, the health impact of WPT becomes increasingly important to consider. In this paper we look at how to maximize the wireless power transfer to remote devices, while maintaining a safe level...

Large scale track analysis for wide area motion imagery surveillance

Wide Area Motion Imagery (WAMI) enables image based surveillance of areas that can cover multiple square kilometers. Interpreting and analyzing information from such sources, becomes increasingly time consuming as more data is added from newly developed methods for information extraction. Captured from a moving Unmanned Aerial Vehicle (UAV), the...

Model-based architecture optimization for self-adaptive networked signal processing systems

A reconfiguration framework for self-organizing distributed state estimators

A sensor network operating under changing operational conditions will have to adapt to its environment, topology and system performance. In order to obtain this flexible behavior, a reconfiguration framework is proposed for distributed signal processing solutions. The considered example in this article is distributed Kalman filtering, whereas...

A search engine for retrieval and inspection of events with 48 human actions in realistic videos

The contribution of this paper is a search engine that recognizes and describes 48 human actions in realistic videos. The core algorithms have been published recently, from the early visual processing (Bouma, 2012), discriminative recognition (Burghouts, 2012) and textual description (Hankmann, 2012) of 48 human actions. We summarize the key...

Improving moving jam detection performance with V2I communication

Dynamax is a road side based system using the SPECIALIST control algorithm and inductive loops. Dynamax field tests showed that moving jams can be effectively resolved by dynamic speed measures [1,5]. This paper focuses on Dynamax In Car, which extends the road side infrastructure with a V2I cooperative approach. V2I cooperation is used to...

DITCM roadside facilities for cooperative systems testing and evaluation

Cooperative systems are being developed for large scale deployment in the near future. Validation of the performance of cooperative systems, and evaluation of the impact of cooperative applications is crucial before large scale deployment can proceed. The DITCM test site facilitates testing, evaluation, and validation of cooperative systems in...

Recognition and localization of relevant human behavior in videos

Ground surveillance is normally performed by human assets, since it requires visual intelligence. However, especially for military operations, this can be dangerous and is very resource intensive. Therefore, unmanned autonomous visual-intelligence systems are desired. In this paper, we present an improved system that can recognize actions of a...

REACH, non-testing approaches and the urgent need for a change in mind set

The objectives of REACH cannot be achieved under the current risk assessment approach. A change in mind set among all the relevant stakeholders is needed: risk assessment should move away from a labor-intensive and animal-consuming approach to intelligent and pragmatic testing, by combining exposure and hazard data effectively and trying to...

Meeting thescientific needs ofecological RISK assessment ina regulatory context

Risk assessment and management of new and existing chemicals

An evaluation was made of the recently developed risk assessment methodologies for new and existing chemicals in the European Communities. The evaluation also included the methodologies to prioritize chemicals and procedures for risk management, i.e., the (draft) guidance document for the development of strategies for risk reduction. The way in...
