3DEX: a code for fast spherical Fourier-Bessel decomposition of 3D surveys

Context. High-precision cosmology requires the analysis of large-scale surveys in 3D spherical coordinates, i.e. spherical Fourier-Bessel decomposition. Current methods are insufficient for future data-sets from wide-field cosmology surveys. ...

Involving and training public school teachers in using robotics for education

Francesco Mondada, Michael Bonani, Fanny Riedo, Mariza Freire

The introduction of technology in the public school teaching process could help increasing the weak motivation we can observe toward engineering studies. To achieve this goal, one main obstacle is motivating public school teachers to use technological tool ...

Ubiquity of non-diffusive momentum transport in JET H-modes

Henri Weisen, Yann Camenen, Mikhail Maslov

A broad survey of the experimental database of neutral beam heated baseline H-modes and hybrid scenarios in the JET tokamak has established the ubiquity of non-diffusive momentum transport mechanisms in rotating plasmas. As a result of their presence, the ...

Benefits and Scepticism of Ecolabels as Accountability Mechanism

Ralf Seifert, Joana Maria Comas Marti

Environmental labelling is an accountability mechanism for firms to satisfy growing demands to prove that value chains are sustainably managed. Although the large variety of ecolabels available today can be interpreted as a sign of their success, it is ove ...

High-resolution 3D condition survey of a masonry arch bridge using Ground Penetrating Radar

Eugen Brühwiler, Alexis Kalogeropoulos

Condition surveying is essential before rehabilitation and modification of a structure. It implies information collection and analysis for structural performance evaluation. Common condition surveying often requires obstructive and invasive techniques that ...

Absorptive capacity, efficiency effect and competitors’ spillovers

Stéphane Lhuillery

Standard innovation surveys do not consider incoming spillovers for non-innovative firms. As a consequence, usual empirical works may overestimate the absorptive capacity effect, particularly among competitors. The Swiss innovation surveys presented here m ...

Models capturing latent constructs

Michel Bierlaire, Aurélie Glerum

In the context of the development of hybrid choice models (HCM), we are interested in understanding better how to design models which can account for the latent information contained in new data types (psychometrics, data from smartphones, etc.) for which ...

Hydrological Importance and Water Quality Treatment Potential of a Small Freshwater Wetland in the Humid Tropics of Costa Rica

Manon Bachelin

Rapid increases in population and growing food demand are causing widespread deterioration of tropical wetlands globally, and an increased focus on the role and function of these imperiled ecosystems is required. Objectives of this study were to investigat ...

Generalized Algorithms for Crew Planning: Survey and Future Directions for Railways

Michel Bierlaire, Olivier Gallay, Prem Kumar

This paper studies the crew planning problem as observed in the transportation industry. We first survey the existing literature on crew scheduling applications in railways and airlines. Next, we identify the synergies in the two domains and propose new di ...

Do firms know the scope of their R&D network? An empirical investigation of network awareness on French survey data

Stéphane Lhuillery

Although research and development (R&D) networks influence the innovation performance of their members, firms may not be fully aware of the scope of their network. In particular, due to cost reasons, they may not be fully informed of their “indirect ties”, ...
