Modelling hybrid demand (e-commerce " plus " traditional) evolution: A scenario planning approach

Rémy Glardon, Naoufel Cheikhrouhou, Luca Canetta

This work presents a "3 steps-2 aggregation levels" methodological approach for modelling the evolution of the hybrid demand order flow pattern over long time horizons. The hybrid demand is the result of the mutual interaction between the e-commerce and th ...

Soft control of swarms: Analytical approach

Max-Olivier Hongler, Guillaume Adrien Sartoretti

We analytically study the collective dynamics of mutually interacting heterogeneous agents evolving in a random environment. Our formal framework consists of a collection of JV scalar drifted Brownian motions (BM) diffusing on R. The mutual interactions ar ...

Assessing functional connectivity of neural ensembles using directed information

Michael Christoph Gastpar

Neurons in the brain form highly complex networks through synaptic connections. Traditionally, functional connectivity between neurons has been explored using methods such as correlations, which do not contain any notion of directionality. Recently, an inf ...

Using Markov switching models to infer dry and rainy periods from telecommunication microwave link signals

Alexis Berne, Marc Schleiss, Zheng Wang

A Markov switching algorithm is introduced to classify attenuation measurements from telecommunication microwave links into dry and rainy periods. It is based on a simple state-space model and has the advantage of not relying on empirically estimated thres ...

Audio-visual synchronization recovery in multimedia content

Touradj Ebrahimi, Jong Seok Lee

This paper proposes a method recovering audio-visual synchronization of multimedia content. It exploits the correlation between the acoustic and the visual signals in order to estimate the audio-visual drift existing in the content. By shifting the audio s ...

Assessing directed information as a method for inferring functional connectivity in neural ensembles

Michael Christoph Gastpar

Neurons in the brain form complicated networks through synaptic connections. Traditionally, functional connectivity between neurons has been analyzed using simple metrics such as correlation, which do not provide direction of influence. Recently, an inform ...

26Mg labeling of the sea urchin regenerating spine: Insights into echinoderm biomineralization process

Anders Meibom, Jaroslaw Hubert Stolarski, Christophe Kopp

This paper reports the results of the first dynamic labeling experiment with regenerating spines of sea urchins Paracentrotus lividus using the stable isotope Mg-26 and NanoSIMS high-resolution isotopic imaging, which provide a direct information about the ...

Hydrologic controls and anthropogenic drivers of the zebra mussel invasion of the Mississippi-Missouri river system

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Marino Gatto

We propose a novel ecohydrological model for the invasion of inland waters by the zebra mussel Dreissena polymorpha and test it against field data gathered within the Mississippi-Missouri river system in North America. This biological invasion poses major ...

Mutual information measures for subclass error-correcting output codes classification

Nikolaos Arvanitopoulos Darginis

Error-Correcting Output Codes (ECOCs) reveal a common way to model multi-class classification problems. According to this state of the art technique, a multi-class problem is decomposed into several binary ones. Additionally, on the ECOC framework we can a ...
