Metabolism of sulphonated anthraquinones in rhubarb, maize and celery: the role of cytochromes P450 and peroxidases

Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation, and thus contaminating many industrial effluents and rivers. In the development of a phytotreatment to remove sulphonated aromatic compounds, rhu ...

DMCMN: In Depth Characterization and Control of AFM Cantilevers With Integrated Sensing and Actuation

Georg Fantner

New developments in MEMS (microelectromechanical systems) fabrication allowed the development of new types of atomic force microscopy (AFM) sensor with integrated readout circuit and actuator built in on the cantilever. Such a fully instrumented cantilever ...

Modifier-adaptation methodology for real-time optimization

Alejandro Gabriel Marchetti

The process industries are characterized by a large number of continuously operating plants, for which optimal operation is of economic importance. However, optimal operation is particularly difficult to achieve when the process model used in the optimizat ...

Stability of enhanced yield and metal uptake by sunflower mutants for improved phytoremediation

Jean-Paul Schwitzguebel, Erika Nehnevajova, Cécile Bourigault

Plant biomass and metal shoot accumulation are key factors for efficient phytoextraction. In a previous study, chemical mutagenesis has been used to improve the phytoextraction potential of sunflowers. The main goal of the present study was to assess the s ...

Site-Controlled InGaAs Quantum Dots with Tunable Emission Energy

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Marco Felici, Arun Mohan

Semiconductor quantum-dot (QD) systems offering perfect site control and tunable emission energy are essential for numerous nanophotonic device applications involving spatial and spectral matching of dots with optical cavities. Herein, the properties of or ...

Swarm-bots to the Rescue

Francesco Mondada, Michael Bonani, Roderich Gross

We explore the problem of resource allocation in a system made up of autonomous agents that can either carry out tasks individually or, when necessary, cooperate by forming physical connections with each other. We consider a group transport scenario that i ...

Quality embedded intelligent remanufacturing

Young Seok Kim

This thesis is motivated from the four keywords: remanufacturing, quality, multi-agent and intelligence. Recent years' environmental problems caused tightening the regulations and legislations for used products. Therefore remanufacturing is getting more at ...

Reverse-engineering of Artificially Evolved Controllers for Swarms of Robots

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert

It is generally challenging to design decentralized controllers for swarms of robots because there is often no obvious relation between the individual robot behaviors and the final behavior of the swarm. As a solution, we use artificial evolution to automa ...

Transient Behavior of variable speed pump-turbine units

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Basile Kawkabani, Yves Pannatier, Alexander Schwery

This paper presents the modeling, simulation and analysis of the dynamic behavior of a fictitious 2x320 MW variable speed pump-turbine power plant including hydraulic system, electrical installations, rotating inertias and control systems. First, the model ...

Modeling and Transient Simulation of FACTS in Multi-Machine Power Systems

Jean-Jacques Simond, Basile Kawkabani, Yves Pannatier

The present paper describes the modeling of 3-level Unified Power Flow Controllers (UPFC) with their control systems for studying the steady-state and transient behavior of electrical networks equipped with FACTS devices. The control features of these devi ...
