BL-Viz4D: A Digital Twin viewer for Maintenance
BL-VIZ4D is a research project led by Berger-Levrault, dedicated to the visualization, synchronization, and interaction with digital twins applied to maintenance. Stemming from thesis work conducted in partnership with the LIRIS laboratory (Laboratory of Image Informatics and Information Systems), BL-VIZ4D explores the scientific and technological foundations of a multi-scale 3D viewer capable of aggregating heterogeneous geospatial data—attribute, 2D, and 3D—and linking it to CMMS business processes. The viewer allows for

BL.Optim, a better visualization for a better organization
Scheduling staff interventions can easily become a hard work with all the constraints to consider (working time, required skills, localization…). So our team worked on an optimized engine which generates a relevant schedule according to the constraints and standards added by the user (see the corresponding articles for CARL Source or BL.Domicile). But we wondered:

Meet Tiago : The future elderly’s best friend
Since August and this article explaining the context and the methodology, our team has used to co-design a social mobile robot with healthcare professional; Tiago has grown up.He has been designed to help and entertain elderly people but also to support caregivers in health services and institutions (EHPAD, day care, rehabilitation center, SSIAD, SSAD).Studying the

Semantic Mediation for Data Exchange
In the current socioeconomic context, companies must work together. Interoperability, which is the action to work together through systems is an unconditional factor to do so. To work, the information shared needs to be compatible. Information can be incompatible when they’re built differently by people or systems.Mediation goal is to manage syntactic and semantic information

Using an interactive information visualization to improve administrative management workflows
The time spent processing administrative requests has an impact on citizen satisfaction. Improving administrative workflows is therefore an important objective for town halls. A workflow is made of a starting point, several parallel or sequential process steps (containing one to several actions, and a theoretical completion time) and decision points (Figure 1) to be processed

Augmented Reality to help remote assistance
We’ve all been in this situation, doing a manual job while following instructions (to realise a recipe or building your new furniture for instance). How pleasant would it be to have your hands free while processing the actions list?Augmented Reality allows integrating 2D or 3D virtual elements (visuals, acoustic…) to the user world perception. This

Software testing hyper automatization with Artificial Intelligence
Nowadays, societies evolve at a fast pace. These evolution involve changes in our tools. It’s the case with software, they must evolve and stay updated to answer our needs. But, how to make sure software answer our needs despite evolution? A popular and effective way is testing. A test will check a software behavior to

Migrating internationalization files
During my Ph.D. migration project, I consider the migration of several GUI aspects: Visual, Behavioral and Business. These elements are the main ones. When perfectly considered, you can migrate the front-end of any application. But, we are missing some other stuff 😄 For example, how do you migrate i18N files? In this post, I’ll present how to build a simple migration tool to migrate I18N files from .properties (used by Java)

How to apply Christoffel-Darboux kernel on online anomaly detection with few parameterization
Incremental properties Kevin Ducharlet is Ph.D. Candidate in the DRIT team. Since a year and a half, he started his thesis entitled: “Certification and confidence in sensor data: detection of outliers and abnormal values in time series.” Sensor data are generated using devices which measure a physical asset’s behaviour. These informations can be used to
