Future manufacturing will be characterized by the complementarity between humans and automation, especially regarding the production of highly customizable products. This requires new methods and tools for the design and operation of optimized manufacturing workplaces in terms of ergonomics, safety, efficiency, complexity management and work satisfaction. MANUWORK aims to focus on the development of an integrated platform for the management of manufacturing workplaces of the future. This will be done through development, implementation and testing of the following technological components: 1. A tool for determining optimal human-automation levels for load balancing, based on methods for the assessment of physical, sensorial and cognitive capabilities of humans, the prediction of evolution of human skills/capabilities using Petri Nets and the modeling of automation skills. 2. A framework for the evaluation of worker satisfaction, safety and health, based on methods for evaluating psychometrics and socio-organizational parameters and the safe human-automation symbiosis. 3. A framework for the adaptive shop-floor support and industrial social networking based on an Augmented Reality tool for the Human-Automation Interface, an industrial social networking platform and methods for knowledge capturing and social analytics. A critical target will be the active and passive use of information from workers, without storing any personal data, in order to maintain the confidentiality of the person involved. This will be done through the direct use of data for the calculation of factors of workplace models for the dynamic assignment of workers based on the groups they belong to (e.g. age group). Finally, MANUWORK will test and validate the research and technological developments in three industrial pilot demonstrators (aerospace, automotive and people with disabilities), following an industrial pre-pilot validation (machine tool sector).

For decades, most of the aviation research activities have been focused on the reduction of noise and NOx and CO2 emissions. However, emissions from aircraft gas turbine engines of non-volatile PM, consisting primarily of soot particles, are of international concern today. Despite the lack of knowledge toward soot formation processes and characterization in terms of mass and size, engine manufacturers have now to deal with both gas and particles emissions. Furthermore, heat transfer understanding, that is also influenced by soot radiation, is an important matter for the improvement of the combustors durability, as the key point when dealing with low-emissions combustor architectures is to adjust the air flow split between the injection system and the combustors walls. The SOPRANO initiative consequently aims at providing new elements of knowledge, analysis and improved design tools, opening the way to: Alternative designs of combustion systems for future aircrafts that will enter into service after 2025 capable of simultaneously reducing gaseous pollutants and particles, Improved liner lifetime assessment methods. Therefore, the SOPRANO project will deliver more accurate experimental and numerical methodologies for predicting the soot emissions in academic or semi-technical combustion systems. This will contribute to enhance the comprehension of soot particles formation and their impact on heat transfer through radiation. In parallel, the durability of cooling liner materials, related to the walls air flow rate, will be addressed by heat transfer measurements and predictions. Finally, the expected contribution of SOPRANO is to apply these developments in order to determine the main promising concepts, in the framework of current low-NOx technologies, able to control the emitted soot particles in terms of mass and size over a large range of operating conditions without compromising combustors liner durability and performance toward NOx emissions.

From government to consumer applications, personal identification is an ever increasing concern and demand. Fingerprints are the oldest and the most reliable features to be used because of their singularity and inalterability. The main goal of the PYCSEL project is to develop a low cost thin and large area fingerprint sensing surface enabling the personal identification via the development of a TOLAE technology, combining an organic sensor with a TFT matrix on a plastic foil. Based on the fact that personal recognition requires high resolution (500 dpi) and large (1 up to 4 fingers) sensors, the project focuses on the design, development and integration of a printed pyroelectric PVDF-based sensor layer on a IGZO TFT active matrix on foil and connected to an electronic driver and readout board, resulting in a thin fingerprint conformable sensor with no need for any optical bulky and/or costly extra components integration. Multiple fingerprints capture will be possible with the resulting large area hybrid system whose conformability allow easy further integration and ergonomic use especially for high growth and high value portable security uses. Therefore, it will offer differentiating properties for the portable governmental market as it will exhibit breakthrough in terms of mechanical robustness and conformability. Those advantages will also increase fingerprint sensors penetration into high volume automotive (personalized HMIs), machine tool (user-restricted HMI), buildings (access control) and consumer markets (PCs). The PYCSEL project will also entitle a transfer from LAB proof of concept to Technological validation in relevant environment. The final large area fingerprint sensor prototype will be able to acquire 4 fingers at a time, with an objective resolution of 500 dpi, and will allow the running of biometric acquisition campaigns as well as demonstration of safety control in automotive application by end-users.

MINOTORs strategic objective is to demonstrate the feasibility of the ECRA technology as a disruptive game-changer in electric propulsion, and to prepare roadmaps paving the way for the 2nd EPIC call, in close alignment with the overall SRC-EPIC strategy. Based on electron cyclotron resonance (ECR) as the sole ionization and acceleration process, ECRA is a cathodeless thruster with magnetic nozzle, allowing thrust vectoring. It has a considerable advantage in terms of global system cost, where a reduction of at least a factor of 2 is expected, and reliability compared to mature technologies. It is also scalable and can potentially be considered for all electric propulsion applications, from microsatellites to space tugs. Although the first results obtained with ECRA have been encouraging, the complexity of the physics at play has been an obstacle for the understanding and development of the technology. Thus an in-depth numerical and experimental investigation plan has been devised for the project, in order to bring the technology from TRL3 to TRL5. The strong consortium is composed of academic experts to perform the research activities on ECRA, including alternative propellants, along with experienced industrial partners to quantify its disruptive advantages on the propulsion subsystem and its market positioning. ECRAs advantages as an electric thruster technology can be a disruptive force in a mostly cost-driven satellite market. It would increase European competitiveness, help develop low-cost satellite missions such as constellations, provide end-of-life propulsion, and pave the way for future emerging electric propulsion technologies. The 36 months MINOTOR project requests a total EC grant of 1 485 809 M for an experienced consortium of 7 partners from 4 countries: ONERA (FR, Coordinator), industries Thales Alenia Space (BE), Thales Microelectronics (FR), SNECMA (FR), Universities Carlos III (ES) and Giessen (GE), and SME L-up (FR).

Implementing cryptography on embedded devices is an ongoing challenge: every year new implementation flaws are discovered and new attack paths are being used by real life adversaries. Whilst cryptography can guarantee many security properties, it crucially depends on the ability to keep the used keys secret even in face of determined adversaries. Over the last two decades a new type of adversary has emerged, able to obtain, from the cryptographic implementation, side channel leakage such as recording of response times, power or EM signals, etc. To account for such adversaries, sophisticated security certification and evaluation methods (Common Criteria, EMVCo, FIPS) have been established to give users assurance that security claims have withstood independent evaluation and testing. Recently the reliability of these evaluations has come into the spotlight: the Taiwanese citizen card proved to be insecure, and Snowdens revelations about NSAs tampering with FIPS standards eroded public confidence. REASSURE will (1) improve the efficiency and quality of all aspects of certification using a novel, structured detect-map-exploit approach that will also improve the comparability of independently conducted evaluations, (2) cater for emerging areas such as the IoT by automating leakage assessment practices in order to allow resistance assessment without immediate access to a testing lab, (3) deliver tools to stakeholders, such as reference data sets and an open-source leakage simulator based on instruction-level profiles for a processor relevant for the IoT, (4) improve existing standards by actively pushing the novel results to standardization bodies. REASSUREs consortium is ideal to tackle such ambitious tasks. It features two major circuits manufacturers (NXP, MORPHO), a highly respected side channel testing lab (Riscure), an engaged governmental representative (ANSSI), and two of the most prominent research institutions in this field (UCL, University of Bristol).
