Empirical review of Java program repair tools: a large-scale experiment on 2,141 bugs and 23,551 repair attempts

Thomas Durieux, Fernanda Madeiral, Matias Martinez, Rui Abreu

In the past decade, research on test-suite-based automatic program repair has grown significantly. Each year, new approaches and implementations are featured in major software engineering venues. However, most of those approaches are evaluated on a single benchmark of bugs, which are also rarely…

Méthodes de prétraitement pour les systèmes de codage vidéo linéaire basé SoftCast

Anthony Trioux, François-Xavier Coudoux, Patrick Corlay, M Gharbi

Un nouveau schéma de codage vidéo linéaire dénommé SoftCast a démontré ces dernières années un potentiel élevé pour la diffusion de vidéo sur des canaux sans-fil variant dans le temps. Particulièrement utile en situation de broadcast, il permet d’éviter les problèmes rencontrés dans les systèmes de…, An original wireless video transmission scheme called SoftCast has been recently proposed to deal with the issues encounteredin conventional wireless video broadcasting systems such as cliff effect [1]. In [2], we analyzed and compared two simple pixel-preprocessing methods that help to increase…

Robust Observer-Based Tracking Control Design for Power-Assisted Wheelchairs

Guoxi Feng, Thierry-Marie Guerra, Tran Anh-Tu Nguyen, Lucian Busoniu, Sami Mohammad

Power-assisted wheelchairs (PAW) are efficient means of transportation for disabled persons. The resulting human-machine system includes several unknown parameters such as the mass of the user or ground adhesion. Moreover, the torque signals produced by the human are required to design a robust…

Numerical study of the reflected elastic waves using Rayleigh diffraction integral

Nadir Maghlaoui, Hakim Djelouah, Assia Oudina, Mohamed Ourak, Farouk Benmeddour

In this work, the transient ultrasonic waves radiated by a linear phased array transducer in a liquid then reflected at a liquid solid interface is studied. A model based on the Rayleigh integral is used where the reflection at the plane interface is considered by using the reflection coefficients…

Enhancing the settling time estimation of a class of fixed‐time stable systems

Rodrigo Aldana-Lopez, David Gomez-Gutierrez, Esteban Jiménez-Rodríguez, Juan Diego Sanchez-Torres, Michael Defoort

In this paper, we provide a new nonconservative upper bound for the settling time of a class of fixed-time stable systems. To expose the value and the applicability of this result, we present four main contributions. First, we revisit the well-known class of fixed-time stable systems, to show the…

Experimental characterization of the mechanical behaviour and the failure of multi-sheet and multi-material spot welded assembly

Rami Tounsi, Grégory Haugou, Fahmi Chaari, Nicolas Leconte, Eric Markiewicz

An experimental investigation of the mechanical behaviour of three-sheet multi-material spot welded assembly is performed. An experimental device based on the Arcan principle is developed to test the three-sheet spot welded specimen under pure opening mode, pure shear mode and mixed opening/shear…

Stability analysis of a class of switched nonlinear systems using the time scale theory

Fatima Zohra Taousser, Michael Defoort, Mohamed Djemai, Seddik Djouadi, Kevin Tomsovic

This paper investigates stability for a class of switched nonlinear systems evolving on a non-uniform time domain. The studied class of systems switch between a nonlinear continuous-time and a nonlinear discrete-time subsystem. This problem is formulated using time scale theory where the latter is…

The single-processor scheduling problem with time restrictions: complexity and related problems

Rachid Benmansour, Oliver Braun, Said Hanafi

We consider the single-processor scheduling problem with time restrictions (STR) in order to minimize the makespan, where a set of independent jobs has to be processed on a single processor, subject only to the following constraint: During any time period of length α, the number of jobs being…

Local oscillator frequency offset estimation for low cost sdr receiver

Reda Yagoub, M. Benaissa, Belkacem Benadda, Abdelmalik Taleb-Ahmed

There are currently many low cost software defined radio (SDR) receivers in the market such as RTL-SDR dongles. These devices can be used to receive the radio frequency (RF) signals in the range of their tuners (front-end). The stability and the accuracy of the local oscillator (LO) among the…
