Model reduction and closed-loop control of oscillator and noise-amplifier flows
This work deals with the closed-loop control of disturbances which develop linearly in laminar and incompressible flows. The control of both oscillator and amplifier... -
Design of Feedback Controls Supporting TCP based on Modern Control Theory
This paper investigates how to design feedback controls supporting TCP (Transmission Control Protocol) based on modern control theories. The present paper studies a... -
TCP Throughput Analysis under Transmission Error and Congestion Losses
This paper analyzes the performance of a large population of long lived TCP flows experiencing random packet losses due to both random transmission errors and... -
A Markovian Model for the Stationary Behavior of TCP
This paper presents a discrete-time Markov chain model for the Reno version of TCP, the transmission control protocol for reliable transport on the Internet. The... -
Etude numérique et expérimentale d'un compresseur aspiré
In order to reduce the mass of aircraft jet engines as well as their fuel consumption, manufacturers tend to make the compression system of their engines more compact,... -

Active control of a separated turbulent boundary layer in adverse pressure gr...
Flow control allows to suppress boundary layers separation, which largely deteriorates the performances of machineries which interact with fluid (aircraft, cars,... -
Passive flow control around a 2D semi-circular cylinder using porous media
The passive control of flow past a semi-circular cylinder is carried out. This control is achieved by adding a porous layer between the solid obstacle and the... -

he control of boundary layer separation on the suction side of an airfoil at high angle of attack has been renewed by the possibilities of active control.... -
Equilibria of a Class of Transport Equations Arising in Congestion Control
This paper studies a class of transport equations arising from stochastic models in congestion control. This class contains two cases of loss point process models: the... -
Analysis of the Competition between Wired, DSL and Wireless TCP Flows in an A...
This paper analyzes the performance of a large population composed of several classes of long lived TCP flows experiencing packet losses due to random transmission... -
A Square Root Formula for the Rate of Non-Persistent TCP Flows
In this paper, we derive a closed form formula for the average rate attained by a non persistent TCP source which alternates between idle periods and download periods... -
Flow Control as Stochastic Optimal Control Problem with Incomplete Information
The nonlinear stochastic control problem related with flow control is considered. The state of the link is described by controlled hidden Markov process while the loss... -
HTTP Turbulence
In this paper, we consider a set of HTTP flows using TCP over a common drop-tail link to download files. After each download, a flow waits for a random think time... -
