Positive association of walking with the use of public transport in Switzerland

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet, Derek Pierre Christie, Jean Simos

Promoting physical activity and active transport strategies are among the “best buys” for tackling the risk factors of noncommunicable diseases (WHO Global status report on noncommunicable diseases, 2010). Operationalising such insights requires policies f ...

Estimation of pedestrian origin-destination demand in train stations

Michel Bierlaire, Flurin Silvan Hänseler, Nicholas Alan Molyneaux

We present a framework for estimating pedestrian demand within a train station. It takes into account ridership data, and various direct and indirect indicators of demand. Such indicators may include link flow counts, density measurements, survey data, his ...

MATHICSE Technical Report : Semi-implicit BDF time discretization of the Navier-Stokes equations with VMS-LES modeling in a High Performance Computing framework

Luca Dede', Davide Forti

In this paper, we propose a semi–implicit approach for the time discretization of the Navier–Stokes equations with Variational Multiscale–Large Eddy Simulation turbulence modeling (VMS–LES). For the spatial approximation of the problem, we use the Finite E ...

Attitudes to Distance, Time and Cost in Logit Transport Choice Models

Matthieu Marie Cochon de Lapparent

During the last 20 years, a distance variable has sometimes been added to specifications of Logit utility functions that already included travel time and cost variables long assumed in theory and practice to embody the impeding effect of distance on transp ...

Developing a 3D finite element model for reinforced concrete

Lucas Henri Galilée Frérot

The embedded model is used in finite elements to account for the influence of the reinforcement in concrete. This report describes the embedded model, its concept and equations. Details are also given as to the constitutive relations of concrete and steel. ...

Iterative Potts and Blake-Zisserman minimization for the recovery of functions with discontinuities from indirect measurements

Martin Kurt Storath

Signals with discontinuities appear in many problems in the applied sciences ranging from mechanics, electrical engineering to biology and medicine. The concrete data acquired are typically discrete, indirect and noisy measurements of some quantities descr ...

Fundamental Power Limits of SAR and ΔΣ Analog-to-Digital Converters

Andrea Bonetti, Luca Bettini

This work aims at estimating and comparing the power limits of ΔΣ and charge-redistribution successive-approximation register (CR-SAR) analog-to-digital converters (ADCs), in order to identify which topology is the most power-efficient for a target resolut ...

Interdiction Games on Markovian PERT Networks

Daniel Kuhn, Wolfram Wiesemann, Eli Gutin

In a stochastic interdiction game a proliferator aims to minimize the expected duration of a nuclear weapons development project, and an interdictor endeavors to maximize the project duration by delaying some of the project tasks. We formulate static and d ...
