Méthodologie de la synthèse des systèmes énergétiques industriels

Raffaele Bolliger

This work presents a synthesis method that leads to the preliminary design of industrial energy systems. Such systems are composed of several technologies that transform, through a set of physical unit operations, raw materials and energy into products and ...

LHC interaction region upgrade

Riccardo De Maria

The thesis analyzes the interaction region of the Large Hadron Collider (LHC). It proposes, studies and compares several upgrade options. The interaction region is the part of the LHC that hosts the particle detectors which analyze the collisions. An upgra ...

Real-time optimization of continuous processes via constraints adaptation

Dominique Bonvin, Benoît Chachuat, Alejandro Gabriel Marchetti

In the framework of process optimization, measurements can be used to compensate for the effect of uncertainty. The method studied in this paper combines a process model and measurements to iteratively improve the operation of continuous processes. Unlike ...

Analytical design and optimization of ultrasonic vibrational transducers for spinal surgery

John Murphy

Just about every other technical publication you pick up these days makes sweeping statements concerning the pressures on scientists, engineers, and industries as a whole to get to market in less time, with an improved, less expensive product. I am reminde ...

Solving issues in the estimation of econometric models

Michel Bierlaire, Michaël Clément Louis Ghislain Thémans

Econometric models play an important role in transportation analysis. Estimating more and more complex models becomes problematic. The associated log-likelihood function is highly nonlinear and non concave and the comlexity of the model requires constraint ...

A Scalable Method for Multiagent Constraint Optimization

Boi Faltings, Adrian Petcu

We present in this paper a new complete method for distributed constraint optimization. This is a utility-propagation method, inspired by the sum-product algorithm (Kschischang et al 2001). The original algorithm requires fixed message sizes, linear memory ...

A Distributed, Complete Method for Multi-Agent Constraint Optimization

Boi Faltings, Adrian Petcu

We present in this paper a new complete method for distributed constraint optimization. This is a utility-propagation method, inspired by the sum-product algorithm. The original algorithm requires fixed message sizes, linear memory, and is time-linear in t ...
