Multiscale interactions between surface shear stress and velocity in turbulent boundary layers

Understanding and quantifying the multiscale interactions between surface shear stress and velocity in the boundary layer is essential to improving boundary condition parameterizations used in numerical models of turbulent boundary layers. In this study, h ...

A generalized correlation for equilibrium of forces in liquid-solid fluidized beds

Albert Renken

A review of publication on the expansion of fluidized bed with the fluid velocity. The well-known Richardson-Zaki equation is applied to develop a more accurate relation linking the apparent drag force Fd, the effective gravitational force Fg, and the void ...

A Dynamic Analysis of Takeover Deals with Competition and Imperfect Information

Erwan Morellec

This article develops an equilibrium framework for the joint determination of the timing and the terms of takeovers in the presence of competition and imperfect information. The model analyzes takeovers as exchange options and derives equilibrium restructu ...

Iterative Correlation-Based Controller Tuning: Application to a Magnetic Suspension System

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

Iterative tuning of the parameters of a restricted-order controller using the data acquired in closed-loop operation seems to be a promising idea, especially for tuning PID controllers in industrial applications. In this paper, a new tuning approach based ...

Solution versus vapor growth of dipolar layers on activated oxide substrates

Frank Nüesch, Libero Zuppiroli, Michel Carrara

Monolayer adsorption of benzoic acid derivatives on activated oxide surfaces from solution and from the vapor phase are investigated with the view of modifying the work function of a conductive substrate. Para-substituted benzoic acids with a wide range of ...

The role of clustering effects in interpreting nondiffusive transport measurements in tokamaks

Jonathan Graves

Recent measurements in tokamak plasmas provide clear evidence for rapid nondiffusive transport and non-Gaussian fluctuations, and have been widely interpreted in terms of the sandpile and self-organized criticality (SOC) paradigms. Many of the statistical ...

Text Segmentation and Recognition in Complex Background Based on Markov Random Field

Hervé Bourlard, Jean-Marc Odobez, Datong Chen

In this paper we propose a method to segment and recognize text embedded in video and images. We modelize the gray level distribution in the text images as mixture of gaussians, and then assign each pixel to one of the gaussian layer. The assignment is bas ...

Exploring Unstsable Periodic Orbits Using Super Stable Ones

This paper deals with Super Stable Orbits (SSOs) of the logistic map, and how they can be used to describe Unstable Periodic Orbits (UPOs).~We will show that Unstable Periodic Orbits have almost the same correlation properties as Super Stable ones from whi ...

Relationships between physicochemical properties and the photoreactivity of four biorecalcitrant phenyl-urea herbicides in aqueous TiO2 suspension

César Pulgarin

The degradation of metobromuron (MB), isoproturon (IP), chlortoluron (CT), and chlorbromuron (CB) in heterogeneous photocatalytic solution via TiO2 was studied in detail. The influence of parameters such as TiO2 and herbicide concentration has been investi ...
