Modeling Route Choice Behavior From Smart-phone GPS data

Michel Bierlaire, Jingmin Chen, Jeffrey Newman

Abstract GPS capable smart phones are emerging survey tools in transportation research field, especially in modeling individuals' mobility patterns. In route choice modeling, path observations need to be generated explicitly for the estimation. It is a cha ...

Constraint-Specific Recovery Networks for Solving Airline Recovery Problems

Michel Bierlaire, Matteo Salani, Niklaus Eggenberg

In this paper, we consider the recovery of an airline schedule after an unforeseen event called disruption, making the planned schedule infeasible. We present a modeling framework that allows the consideration of operational constraints within a Column Gen ...

Parametric Sensitivity of Path-Constrained Optimal Control: Towards Selective Input Adaptation

Dominique Bonvin, Benoît Chachuat, Saurabh Anand Deshpande

In the context of dynamic optimization, plant variations necessitate adaptation of the input profiles in order to guarantee both feasible and optimal operation. For those problems having path constraints, two sets of directions can be distinguished in the ...

Software Transactional Memory on Relaxed Memory Models

Rachid Guerraoui, Vasu Singh

Pseudo-code descriptions of STMs assume sequentially consistent program execution and atomicity of high-level STM operations like read, write, and commit. These assumptions are often violated in realistic settings, as STM implementations run on relaxed mem ...

Identifying Dominant People in Meetings from Audio-Visual Sensors

Daniel Gatica-Perez

This paper provides an overview of the area of automated dominance estimation in group meetings. We describe research in social psychology and use this to explain the motivations behind suggested automated systems. With the growth in availability of conver ...
