TIS in brief
This field covers what is usually referred to as sciences and technologies of information and communication, the main components of which are automatic control, signal and image processing, robotics, digital simulation, system and process design and optimization, computer systems engineering, knowledge engineering and cognitive processes.
Much of the research is aimed at the design of aeronautical and aerospace systems, defense and surveillance systems and security systems, as well as the deployment of these systems in complex missions, the processing of massive data from on-board sensors and the development of knowledge about large-scale phenomena. The generic nature of this work means that it has considerable diversification potential, particularly in transport and production systems.
Through innovative digital methods and techniques, and the convergence of modeling, simulation and data, this work aims to make advances that will enable new intrinsic performances to be achieved for the systems in question. It also addresses issues relating to their integration into information and communication systems, and to the need for interactivity with users, as well as safety, security, autonomy and system coordination.
Many of these projects give rise to experimental developments (mini-UAVs and UAVs, land and submarine robots, piloting aid interfaces, intelligent sensor networks, etc.). Others involve the development of software platforms (air traffic, battle lab, MDO design, etc.) to create digital models and evaluate operational performance through physical simulation.
The TIS domain comprises 8 scientific themes, mainly spread across the DTIS Information Processing and Systems department (and, for one theme, the DAAA Aerodynamics, Aeroelasticity, Acoustics department).

DELTA A software environment designed to facilitate the use of deep learning (CNN, RNN, GAN) in ONERA's business activities. DELTA has been used for point cloud semantization, weather prediction (lightning risk and electronic content of the ionosphere), propellant combustion studies, crack counting in composite materials, and fluid mechanics. DELTA is mainly based on Pytorch (although a Caffe version still exists), and relies on an ONERA cluster of new-generation Nvidia GPUs.
InCell is a Constraint Programming tool for managing several types of renewable resources. It considers disjunctive resources, cumulative resources and resources with an appropriation period. Conflicts over resource use are resolved by prioritizing activities for scheduling. In addition, the tool includes an invariant for constraint-based differentiable local search, which transforms a priority order into a complete schedule and incrementally manages this schedule in the event of a change in the order. On this basis, several neighborhoods and search strategies can be used, and new best upper bounds have been obtained for several scheduling benchmarks. The spatial domain is a key application of InCELL.
