Observability and Observer Design of Partially Observed Petri Nets

Fayssal Arichi, Petreczky Mihaly, Mohamed Djemai, Brahim Cherki

This paper investigates observability and observer design of partially observed Petri nets (POPN). By using methods for descriptor systems, two major contributions are presented. First, a novel algebraic condition for POPN observability is presented. Second, an asymptotic observer is constructed…

Different surface sensing of the cell body and nucleus in healthy primary cells and in a cancerous cell line on nanogrooves

Patricia Davidson, Maxence Bigerelle, Gunter Reiter, Karine Anselme

Cancer cells are known to have alterations compared to healthy cells, but can these differences extend to the way cells interact with their environment? Here, the authors focused on the alignment on an array of grooves of nanometer depth using two cell types: healthy osteoprogenitor primary cells (…

On the study of human reliability in transportation systems of systems

Subeer Rangra, Walter Schön, Mohamed Sallak, Frédéric Vanderhaegen

Humans are and will remain one of the critical constituents of a technological system. The study of Human Factors is a broad domain with equally varying applications. Quantification thereof, with a Human Reliability Analysis (HRA) poses considerable challenges and advantages. In increasingly…

Design of a device to induce swirling flow in pipes: A rational approach

François Beaubert, Halldor Pálsson, Sylvain Lalot, Isabelle Choquet, Hadrien Bauduin

In this study, a rational approach is proposed to design a device for inducing swirling flow in heat exchanger pipes, for improved efficiency in the laminar regime. First, 2D computational fluid dynamics results lead to select, among four profiles, the blade profile with the most favorable lift to…

Low Velocity Impact Behavior of Glass Fibre-Reinforced Polyamide

Jamel Mars, Mondher Wali, Rémi Delille, Fakhreddine Dammak

The low velocity impact behavior of composites made of polyamide (PA) as matrix and glass fibre as reinforcement has been investigated. The assessment of the impact behavior has driven the need to perform tensile tests to determine the elasto-plastic behavior of the composites. The specimens were…
