Séminaire DEVI – Cherie Lu (Chang Jung Christian University, Tainan, Taiwan)

21/11/2019 @ 10h30 – 11h30 – When will biofuels be economically feasible for commercial flights? Abstract This paper evaluates the financial outlays and environmental costs of using biofuel and traditional aviation fuel for selected flight routes. Cost-benefit analysis and the dose-response method were applied for evaluating the financial and environmental costs of both biofuels and traditional fuel. Selected flight routes originating […]

Séminaire DEVI – Agnès Lagnoux (IMT Toulouse)

24/10/2019 @ 10h30 – 11h30 – Sur l’estimation de paramètres de covariance de processus gaussiens Résumé : En raison de leur simplicité et de leur flexibilité permettant ainsi de modéliser une large classe de modèles, les processus gaussiens sont devenus très populaires depuis quelques années et largement utilisés en statistique spatiale afin d’interpoler les observations et proposer un métamodèle (de krigeage […]

Séminaire DEVI – Willy Rodríguez (ENAC)

10/10/2019 @ 10h30 – 11h30 – Mathematical models for the evolution of species in the era of genetic data Abstract: One of the aims of population genetics is to date and quantify major events that arrived during the evolution of species. The DNA sequencing techniques and the increasing amount of genomic data currently available are expanding the horizons of the field. Over the last decade, a […]

Séminaire DEVI – Claudio Piga (Huddersfield University Business School)

26/09/2019 @ 10h30 – 11h30 – Linking Algorithms to Static and Dynamic pricing: theory and evidence Abstract: We show how the main features of a pricing algorithm  are shaped by organizational frictions, which impede continuous  price adjustments. In our theoretical multi-unit capacity, multi-period pricing model, frictions lead the algorithm to set prices for each unit, which remain constant during a « static pricing […]

Séminaire DEVI – Tat-Dat Tô

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 […]

Séminaire DEVI – Michel Boyom (université Montpellier II)

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. […]

Séminaire DEVI – Jean-Pierre Florens (TSE)

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 […]

Séminaire DEVI – Xavier Fageda (Université de Barcelone)

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 […]

Worshop Agency Research Team (ART) : « Aviation Economics and Business Models »

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
