Inferences from catchment-scale tracer circulation experiments

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

In this paper the mechanisms determining the mobilization and transport of solutes driven by rainfall through runoff pathways at catchment scales are investigated through the analysis of tracer experiments. The hydro-chemical response of a small catchment ...

Real-time Optimization with Estimation of Experimental Gradient

Dominique Bonvin, Benoît Chachuat, Alejandro Gabriel Marchetti

For good performance in practice, real-time optimization schemes need to be able to deal with the inevitable model-mismatch problem. Unlike the two-step schemes combining parameter estimation and optimization, the modifier-adaptation approach uses experime ...

Development of Micromorph Cells in Large-Area Industrial Reactor

Christophe Ballif, Matthieu Despeisse, Grégory Bugnon, Andrea Feltrin, Gaetano Parascandolo, Adrian Billet

The influences of the deposition pressure and silane depletion on the efficiency of single-junction microcrystalline silicon solar cells has been investigated. The efficiency is found to correlate with the ion energy which affects the density of states in ...

Novel design of a microstructured reactor allowing fast temperature oscillations

Albert Renken, Lioubov Kiwi, Martin Luther

Two types of stainless steel microstructured reactors for catalytic gas-phase reactions have been developed and characterized with respect to their thermal behaviour under non-stationary temperature conditions. One of the reactors used (FTC-I) allowed peri ...

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 ...

Robust Predictive Control Based on Neighboring Extremals

Dominique Bonvin, Sébastien Gros

The performance of a predictive controller is typically poor when the true plant evolution deviates significantly from that predicted by the model. A robust control approach that considers model uncertainty explicitly is then needed. However, it is often d ...

TiO2-photocatalyzed As(III) oxidation in a fixed-bed, flow-through reactor

Janet Gordon Hering

Compliance with the U.S. drinking water standard for arsenic (As) of 10 μg L-1 is required in January 2006. This will necessitate implementation of treatment technologies for As removal by thousands of water suppliers. Although a variety of such technologi ...

A thermodynamic model for the precipitation of nanostructured copper oxalates

Heinrich Hofmann, Paul Bowen, Jacques Lemaître, Lucica Soare

A thermodynamic model is developed for the precipitation of copper oxalate from aqueous solutions of copper nitrate and sodium oxalate in a small well-mixed batch reactor. This model is then used to explain the discrepancy between experimental pH evolution ...

Liquid-core capsules as a tool in biotransformations

The aim of this thesis was to develop a new type of liquid-core capsules obtained by co-extrusion using the laminar jet break-up technique. These capsules, composed of an organic phase as the core and a hydrogel membrane, were meant to be applied as an in- ...
