Comparative analysis of various techniques to improve the performance of novel wheat germ oil – an experimental study

Edwin Geo Varuvel, C. Prabhu, Shanmugam Thiyagarajan, T. Maiyalagan, Fethi Aloui

The current study aims to explore the opportunities of using the high viscous biofuel namely Wheat Germ oil (WGO) in a twin cylinder CI engine. High viscous fuels suffer from improper atomization leading to poor combustion and higher smoke emission. To address this problem, various techniques…

Numerical simulation of water spray transport along a plate of a heat exchanger

Nihel Grich, Walid Foudhil, Souad Harmand, Sadok Ben Jabrallah

Water spraying is widely being used in many industrial applications because of the benefits it has shown over cooling. This paper presents a numerical investigation to simulate evaporating water spray along a plate of an exchanger. Indeed, we were interested in a horizontal channel whose lower wall…

Industry 4.0: contributions of holonic manufacturing control architectures and future challenges

William Derigent, Olivier Cardin, Damien Trentesaux

The flexibility claimed by the next generation production systems induces a deep modification of the behaviour and the core itself of the control systems. Over-connectivity and data management abilities targeted by Industry 4.0 paradigm enable the emergence of more flexible and reactive control…

Continuous Monitoring of Whey Protein Fouling Using a Nonintrusive Sensor

Laurent Bouvier, Guillaume Delaplace, Sylvain Lalot

In this work, a nonintrusive device to monitor fouling of a plate heat exchanger is presented. This device is composed of a flat electrical resistance covering a thermocouple located on the external face of a tubular holding section. The tubular holding section is placed immediately after the…

A Lyapunov-Like Characterization of Predefined-Time Stability

Esteban Jiménez-Rodríguez, Aldo-Jonathan Muñoz-Vázquez, Juan Diego Sanchez-Torres, Michael Defoort, Alexander Loukianov

This article studies Lyapunov-like conditions to ensure a class of dynamical systems to exhibit predefined-time stability. The origin of a dynamical system is predefined-time stable if it is fixed-time stable, and an upper bound of the settling-time function can be arbitrarily chosen a priori…

On the improvement of calibration accuracy of parallel robots – modeling and optimization

Toufik Bentaleb, Jamshed Iqbal

This paper proposes kinematic based calibration methods for Delta parallel robots. The boundary of the robot workspace is computed using a forward kinematic model. Influence of errors in kinematic parameters on the workspace boundaries is investigated. The novelty of the proposed approach lies in…

Surface Texturization of Breast Implants Impacts Extracellular Matrix and Inflammatory Gene Expression in Asymptomatic Capsules

Isabelle I. Brigaud, Charles Garabedian, Nathalie Bricout, Laurent Pieuchot, Arnaud Ponche, Raphaël Deltombe, Rémi Delille, Michael Atlan, Maxence Bigerelle, Karine Anselme

Background: Texturing processes have been designed to improve biocompatibility and mechanical anchoring of breast implants. However, a high degree of texturing has been associated with severe abnormalities. In this study, the authors aimed to determine whether implant surface topography could also…

Valuing free-form text data from maintenance logs through transfer learning with CamemBERT

Juan Pablo Usuga Cadavid, Bernard Grabot, Samir Lamouri, Robert Pellerin

Coupling a production scheduling process with maintenance logs can provide important advantages. For instance, this enables the adaptation of planning to the reality of the shop floor. Nevertheless, maintenance logs are often highly unstructured, as they mainly rely on free-form text comments from…

Particulate emissions measurements by laser-based techniques in a boiler fueled by wood pellets

Salma Bejaoui, Marie Creyx, Eric Delacourt, Céline Morin, Eric Therssen

This paper describes mainly laser-based techniques applied to a boiler fueled by wood pellets which is a real complicated combustion system. To our knowledge, laser-induced incandescence (LII) and extinction are used to characterize particulate emission at the exhaust for the first time because…

Enhance sentiment analysis on social networks with social influence analytics

Nadia Chouchani, Mourad Abed

Sentiment analysis on social networks has attracted increasing research attention. Most previous works rely on text mining and the phenomenon of Homophily reflected by explicit friendship relations, which are a weak assumption for modeling sentiment and opinion similarities. In this paper we show…
