A Stochastic Hybrid Model for Air Traffic Control Simulation

Abstract: A method for modelling the evolution of multiple flights from the point of view of an air traffic controller is developed The model is multi-agent, hybrid and stochastic It consists of many instances of flights, each with different aircraft dynamics, flight plan and flight management system The motions of different flights are coupled through the effect of the wind, which is modelled as a random field Estimates of the statistical properties of the wind field (variance and spatio-temporal correlation structure) are extracted from publicly available weather data The model is coded in Java, so that it can be simulated to generate realistic data for validating conflict detection and resolution algorithms

Removal of ammonium, iron and manganese from potable water in biofiltration units: a review

Abstract: Ammonium, and trace metals such as iron and manganese are common inorganic pollutants present in waters. Several surface and groundwaters contain natural or increased concentrations of these pollutants that are observed either isolated or in pairs, or all three together. Although several processes have been established for the biological removal of one of the above-mentioned pollutants, only recently have important studies been performed on the efficient and cost-effective simultaneous biological removal of two or more substances. This paper reviews the variety of full- and pilot-scale biological filters that have been used for combined or simultaneous biological removal, as well as factors and conditions that were found to affect the process. The main results regarding research progress on combined or simultaneous biological removal are evaluated. Finally, the kinetic models and simulation approaches used are discussed. © 2013 Society of Chemical Industry

MINERVA: collaborative P2P search

Abstract: This paper proposes the live demonstration of a prototype of MINERVA, a novel P2P Web search engine. The search engine is layered on top of a DHT-based overlay network that connects an a-priori unlimited number of peers, each of which maintains a personal local database and a local search facility. Each peer posts a small amount of metadata to a physically distributed directory that is used to efficiently select promising peers from across the peer population that can best locally execute a query. The proposed demonstration serves as a proof of concept for P2P Web search by deploying the project on standard notebook PCs and also invites everybody to join the network by instantly installing a small piece of software from a USB memory stick.
