At Mines Saint-Étienne, Yann Gavet uses image simulation to study the characteristics of an object. This method is more economical in terms of time and cost, and eliminates the need for experimental measurements. This field, at the intersection of mathematics, computer science and algorithms, is used for a variety of applications ranging from the medical sector to the study of …

Thierry Garaix and Raksmey Phan are systems engineering researchers at Mines Saint-Étienne[1]. In response to the current health crisis, they are making digital simulation and digital twins available to health services to inform their decision-making. This assistance is crucial to handling the influx of patients in hospitals and managing the post-peak period of the epidemic.   The organization of the …

How can we improve emergency room wait times, the way scheduled hospitalizations are managed and cope with unexpected surges of patients? Vincent Augusto, a researcher in healthcare systems engineering at Mines Saint-Étienne is working to find solutions to these problems. He is developing programs based on digital simulation, aimed at optimizing influxes of patients and waiting times at the hospital, …

Digital simulation has become an almost mandatory step in developing new products. But what does “simulating behavior” or “modeling an event” really mean? Marius Preda, a computer science researcher at Télécom SudParis, explains what’s hiding behind these common industry expressions.   What is digital simulation used for? Marius Preda: Its main goal is to reduce prototyping costs for manufacturers. Instead …

Simulate. Prototype. Measure. Repeat. Developing an industrial part inevitably involves these steps. First comes the digital model. Then, its characteristics are assessed through simulation, after which, the first version of the part is built. The part must then be subject to mechanical stress to assess its resistance and be closely observed from every angle. The test results will be used …

To effectively roll out circular economy policies within a territory, companies and decision-makers require access to evaluation and simulation tools. The design of these tools, still in the research phase, necessarily requires a more detailed consideration of the impact of human activities, both locally and globally. “The circular economy enables optimization of the available resources in order to preserve them …

Improving access to large facilities for research on climate and air quality and optimizing use are the objectives of the European ATMO-ACCESS project. Véronique Riffault and Stéphane Sauvage, researchers at IMT Nord Europe, one of the project’s 38 partner institutions, explain the issues involved. What was the context for developing the ATMO-ACCESS project? Stéphane Sauvage – The ATMO-ACCESS project responds to a H2020-INFRAIA …

Designing projects implies that individuals or groups must pool their values to collaborate effectively. But the various parties involved may be guided by diverging value systems, making it difficult to find compromises and common solutions. Françoise Détienne and Michael Baker, researchers at Télécom Paris, explain how the role of values in collective design can be understood. How is a value defined …

How can traffic and public transport be managed more effectively in a city, while controlling pollution, ensuring the safety of users and at the same time, taking into account ethical issues related to the use of data and mechanisms to ensure its protection? This is the challenge facing IMPETUS, a €9.3 million project receiving funding of €7.9 million from the …

The European MANIFESTS project, launched in January, is a two-year project bringing together a consortium of nine research institutions and public administrations with complementary expertise in managing maritime accidents. Funded by the European Commission, this project aims to improve responses to emergencies related to these accidents. An interview with Laurent Aprin, a researcher at IMT Mines Alès, a project partner. Could …
