ESILV’s 5-year engineering students displayed their final-year projects at a showroom held at the Pole De Vinci’s campus, on January 31. The innovative industrial projects, called “PI²5”, enabled students to promote their work to companies, technical students associations and public institutions or to contribute to science through their research projects.
4 out of 43 projects showcased during the event were carried out as a part of the Research track and 3 projects were part of the Innovation track at the De Vinci Innovation Center.
5 Final-Year Projects in the spotlight
Microsoft’s HoloLens project on educational activities at hospitals

The project HoloLens, developed in collaboration with Microsoft, provides educational activities for hospitals, based on an application that allows the growth of a plant in mixed reality.
Aimed at children with special needs, the project presents itself as an innovative educational tool, by means of mixed reality technologies used by HoloLens.
Thanks to this application, children will be able to understand the evolution of the plant, from seed to adult plant. The goal is to take this technology to hospitals.” (Younes Chiboub)
Project for Paris City Hall: Analysing Airbnb’s market data via online users’ behaviours
Airbnb 1: data scraping tool to gather duplicate ads on short term rental sites
Quentin Alais , Ilyess Aggour, Youssef Ben Hammed, Bastian Mollard
The data scraping tool is the upstream project from which the Rental Fraud Prevention Project (Airbnb 2) is ultimately derived.
The Airbnb 1 project is focused on analyzing fraudsters’ data and it aims to answer the question, “How to have a more precise estimate of the number of days that a property can be “short let” on Airbnb and other similar short-let platforms?”
“Landlors using Airbnb are legally obliged to limit the number of rentals to 120 nights a year. Many landlors don’t respect the legislation in Paris and our tool now allows you to check duplicate adds posted on different sites such as Airbnb and Booking, in order to rent out all year round. In terms of technology, we use data scraping: we retrieve ads posted on short-term let sites like Airbnb and all the informations such as : titles, photos, adresses, texts. Next, we compare the ads based on their photos. A fingerprint is generated from these images and we create a fingerprint dictionary which allows us to make the links between all the adds posted on different sites”. (Youssef Ben Hammed)
Airbnb 2: how to precisely calculate the number of rental days for each ad
Rémi de Ferrières, Juliette Desormonts, Paul Fauvet, Thomas Vaquero
The project developed by the second team of student-engineers, who put their skills at the service of the City Hall’s figures, aims to identify owners who are using the rental platforms fraudulently.
” The City Hall’s dataset includes 20,000 or 30,000 ads from landlords who are in a situation of fraud. We have tried to refine this figures, by putting precise figures on the number of illegal ads. 2,5% of the 1000 adds we analyzed are definitely fraudulent.” (Thomas Vaquero)
“We realized that 50% of the ads are permanently displayed on these platforms. We were able to confirm the figures gathered by Paris City Hall”. (Juliette Desormonts)
Data Science Research Project: Matching of data-based food information in Open Food Facts
The Open Food Facts data science team-project
Sophie Botineau-Grébert, Hany Akoury
To carry out their final year research project, Sophie and Hany updated the database of Open Food Facts, the Wikipedia of Food.
“Today the database contains about a million lines, there was a lot of missing or inaccessible data. We did a data cleaning and standardization and removed useless categories. There were even several languages in the database, so we’ve put everything in French and now the database is more ready to be used by new teams for new projects. In the end, we reduced the data at 300-400 complete product lines”.(Hany Akoury)
Innovation track project: TDS Balloon, an ecological and silent alternative to sounding balloon
Zacharia’s TDS Balloon Project
Zacharie Guillaume developed this project as a part of his studies in the Innovation track, at the De Vinci Innovation Center. This weather balloon contains a “lung” that allows him to fly over many different areas, without helium.
“The method I use is to place a second balloon inside, which acts as a lung or ballast of varying size, which allows the balloon to increase its density, so the balloon can go down. This technique had not been developed before and the idea is to use it in much wider applications, for example, in interplanetary or planetary exploration. Thanks to this technology, in 5 minutes, we can have a network of satellites traveling trough Earth’s atmosphere. So, while UAV are noisy and little autonomous, the TDS balloon is of infinite autonomy and zero noise.” (Zacharie Guillaume)
Project included in the Perseus Programme: study of lattice structures for aerospace applications
The study of lattice structures project-team presents the features of the project during the final-year showroom
Thibault Herrera-Mione, Pierrick Boucaud
The 5th year project proposes a solution for the topological optimization of Perseus rocket ailerons and its implementation.
“Perseus programme (the Student Space Program developed by the CNES France) consists of many subjects that can be extended from year to year. This year’s topic is a lattice structure study: a research topic. The aim of the lattice structure is to lighten an element of the rocket structure. The principle is to substract matter around a full component, which would improve its mechanical caracteristics and mass.”(Pierrick Boucaud)
“This year, Leo Fly student association develops six technical projects, a scaleglider, a wind tunnel project. We also make rockets in partnership with CNES as a part of the C’Space campaign Nous faisons également des fusées en partenariat avec le CNES dans le cadre de la campagne C’Space (an yearly rocket launch campaign).” (Florian Chaumeuil, Léo Fly president ).
