With economical energy market strategies based on instantaneous pricings of electricity as function of the demand or the predictions, operators harness more hydroelectric facilities to off-design operating points to cover the variations of the electricity ...
The characterization of the temporal profile of plasmonic fields is important both from the fundamental point of view and for potential applications in ultrafast nanoplasmonics. It has been proposed by Stockman et al (2007 Nat. Photonics 1 539) that the pl ...

In the present work, a label-free, contactless and capacitive immunosensor is developed using impedance spectroscopy, in the aim to perform low-cost immunoassays. Chapter 1 puts this work in perspective with some existing techniques, while a presentation o ...
Small density variations due to low solute concentrations in the stream water commonly exist in streams and rivers. Using laboratory experiments and numerical modeling, we demonstrated that even such small density variations could influence the hyporheic f ...
A novel approach is proposed to obtain an extended depth of focus (DoF) in white light with constant transversal spot size within the DoF. It combines a phase-only pupil filter based on multiplexed radial zones with alternating quartic phase functions. The ...
We study a kinetic mean-field equation for a system of particles with different sizes, in which particles are allowed to coagulate only if their sizes sum up to a prescribed time-dependent value. We prove well-posedness of this model, study the existence o ...
A unified and comparative treatment of traditional potentiometric and amperometric enzyme electrodes and of enzyme reactors is presented. Exact theoretical descriptions are given for limiting cases, and relatively simple approaches for general cases. The l ...
This work addresses the multipactor problem for multi-carrier operation inside rectangular waveguide based devices, by means of numerical simulations of the electron trajectories and multiplication inside the structure. Accurate field calculation and takin ...
In deep geological repository involving a multi-barrier system, the engineered materials, generally made of bentonite, constitute an important mechanical, thermal and hydraulic barrier to prevent the interaction between wastes and biosphere. To better unde ...
In the selective laser melting process, the scanning strategies have a deep impact on the final microstructures. In this paper, we point out the benefits of using EBSD techniques to characterize the scanning strategies on 18-carat gold samples. For a given ...
