12/09/2019 @ 10h30 – 11h30 – A deep learning approach for the shortest path search problem and some perspective applications. We propose a deep learning approach for shortest path search problem in which the shortest length can be learned via a deep Neuron Network. We also propose an algorithm which permit to run the A-star algorithm in real time for the […]
27/06/2019 @ 10h30 – 11h30 – Structuration des systèmes complexes A ce jour, les systèmes complexes sont le plus souvent considérés selon l’angle des espaces mesurables. Néanmoins, les informations susceptibles d’en être tirées peuvent être des invariants issus de structures mathématiques différentes, topologiques ou différentielles. L’objet de cette conférence est de présenter quelques perspectives de structuration des données: Au niveau conceptuel. […]
27/06/2019 @ 10h30 – 11h30 – Structure of complex systems Complex systems are most often considered from the viewpoint of measurable spaces. Nevertheless, this approach can give rise to invariants from different mathematical structures: topological or differential. The purpose of this talk is to present some perspectives on the structuring of data: At the conceptual level. Equipping a *complex system* with […]
13/06/2019 @ 10h30 – 11h30 – Convolution on networks This work analyses the estimation of a linear model Y=Z*b + U where Y,U, Z and b are functions defined on a network and where the convolution operator * is defined through a Fourier transform defined on the network. Networks may be usual networks, homogenous spaces or more generally spaces provided with […]

16/05/2019 @ 15h00 – 16h00 – GLOBALIZATION, LONG-HAUL FLIGHTS AND INTER-CITY CONNECTIONS We estimate a model that identifies the impact of long-haul non-stop flights on traffic flows in inter-city markets, using data that account for the true origin and destination of passengers. In particular, we analyze whether long-haul non-stop flights may have a positive and significant effect on traffic flows in […]

16/04/2019 – 17/04/2019 @ Toute la journée – The workshop focusses on the business models of various aviation stakeholders and how they are likely to evolve in the future, e.g. as a function of new traffic participants as well as the impact of regulation and incentives schemes, including environmental regulation. The workshop is open to additional topics and presentations. Agenda

07/03/2019 @ 10h30 – 11h30 – Causes and Effects of Air Traffic Delays: Evidence from Aggregated Data This study uses aggregated data on concentration, delays, and airfares from the US airports to shed light on two issues. First, we examine the concentration-delays relationship to contribute to the airport- congestion self-internalization debate. Our study is the first investigation of this issue that […]
