Modelling of plunge pool scour evolution in non-cohesive sediments

Giovanni De Cesare, Sebastian Schwindt, Gaël Epely Chauvin

Turbulences in liquids caused by jets can be of interest for numerous applications. For one, it concerns flood spillway structures within civil engineering but also is key in any area where turbulent mixing is present. The numerical simulations of jets tha ...

Controlled reattachment in separated flows: a variational approach to recirculation length reduction

François Gallaire, Edouard Boujo

A variational technique is used to derive analytical expressions for the sensitivity of recirculation length to steady forcing in separated flows. Linear sensitivity analysis is applied to the two-dimensional steady flow past a circular cylinder for Reynol ...

On the MAC for Power-Line Communications: Modeling Assumptions and Performance Tradeoffs

Patrick Thiran, Julien Pierre Sacha Herzen, Christina Vlachou

Power-line communications are becoming a key component in home networking. The dominant MAC protocol for high data-rate power-line communications, IEEE 1901, employs a CSMA/CA mechanism similar to the backoff process of 802.11. Existing performance evaluat ...

Instrument intercomparison in the pulsed neutron fieldsat the CERN HiRadMat facility

Nikolaos Charitonidis, Daniel Perrin

An intercomparison of the performances of active neutron detectors was carried out in pulsed neutron fields in the new HiRadMat facility at CERN. Five detectors were employed: four of them (two ionization chambers and two rem counters) are routinely employ ...

Effect of antecedent conditions and fixed rock fragment coverage on soil erosion dynamics through multiple rainfall events

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The effect of antecedent conditions and specific rock fragment coverage on precipitation-driven soil erosion dynamics through multiple rainfall events was investigated using a pair of 6-m × 1-m flumes with 2.2% slope. Four sequential experiments – denoted ...

Porous media pressure distribution in centrifugal fields

David Andrew Barry

The simplest use of centrifuges to measure soil properties relies on steady state conditions. Analytical solutions, especially if they are simple, make interpretation of data more direct and transparent. Previous approximations are simplified and have a gr ...

Use of Transient Measurements for Real-Time Optimization via Modifier Adaptation

Dominique Bonvin, Grégory François

Real-time optimization (RTO) methods use measurements to offset the effect of uncertainty and drive the plant to optimality. Explicit RTO schemes, which are characterized by solving a static optimization problem repeatedly, typically require multiple itera ...

Data, Parameters & Nonlinearities: Development and Applications of Large-scale Dynamic Models of Metabolism

Vassily Hatzimanikatis, Ljubisa Miskovic, Keng Cher Soh, Anirikh Chakrabarti

Dynamic nonlinear models of metabolism offer a significant advantage as compared to constraint-based stoichiometric descriptions. However, progress in the development of large-scale nonlinear models has been hindered by both structural and quantitative unc ...
