The SAPPHIRE project will develop an integrated prognostics and health management system (PHM) including a health-adaptive controller to extend the lifetime and increase the reliability of heat and power-producing systems based on low-temperature proton-exchange membrane fuel cells (LT-PEMFC). The PHM system can actively track the current health and degradation state of the fuel-cell system, and through the health-adaptive control counteract the degradation of cells and balance of plant, and thereby boost the lifetime of the controlled system beyond the current lifetime expectancy. An important part of project is to develop novel prognostics approaches implemented in the PHM for estimation of the remaining useful life (RUL) of the PEMFC. An efficient sensor configuration for control will be chosen using controllability analysis methods, also including indirect sensing/estimation techniques to replace expensive measurement principles. Based on sensor inputs and input from the control system, the PHM algorithms identify the probable failure modes trajectories and estimate the remaining useful life. The consortiums competence ranges from first principles estimation, to signal processing, regression and data-driven techniques, such as neural networks. This ensures an efficient choice of methods. The project covers a full cycle of research activities, from requirement specification and laboratory experiments, through study of degradation phenomena and selection of prognostic methods, to synthesis of the control system and its testing on the target PEMFC system. A technical-economical analysis will be performed in order to assess the impact of the developed tool in terms of lifetime improvement. The project is expected to produce hardware and software solutions and have a significant scientific output. The implemented solutions resulting from the project will be tested and validated by the research and industrial partners.

The thermal properties of nanostructured materials are of fundamental importance to modern technology, but at present reproducible metrological definitions, tools and methods do not exist. This is because the mechanisms of heat transport at the nanoscale are entirely different to those at the macro scale. The project will place nanothermal metrology on a solid basis by an integrated physics-based experimental and modelling effort to: Define a common terminology for nanothermal measurement Realise standard materials and devices for measurement and calibration of nanothermal measurements Develop new instruments and methods for traceable nanothermal measurement Develop calibrated and validated thermal models covering the range from atomic to macro-scale Apply these tools to selected representative industrial problems Assess the tools for suitability for adoption as potential standards of measurement including their traceability and reproducibility The objectives will be achieved by a team comprising physicists, materials scientists, modellers, instrumentalists, microscopists, industrial partners (including SMEs and OEMs) and National Measurement Institutes. The outputs of QUANTIHEAT will be embodied in highly characterised reference samples, calibration systems, measurement tools, numerical modelling tools, reference measurements and documented procedures. The availability of calibrated numerical modelling tools will facilitate the rapid digital thermal design of new nanosystems without the need for extensive prototyping. Their validation against experiment over all length scales will provide a solid basis for the deployment of new nanostructured materials, devices and structures having optimised performance without the need for excessively conservative design. Standardization is a key driver of industrial and scientific progress: QUANTIHEAT is expected to constitute a de-facto standard for a key area of physical measurement at the nanoscale worldwide.

Lasers form an increasingly common tool for precision treatment of pathological conditions on delicate and vital human organs. Laser phonomicrosurgery, which is a suite of complex otolaryngological surgical techniques for the treatment of minute abnormalities in the larynx, is one such example. However, laser aiming control for this procedure relies completely on the dexterity of surgeons, who must operate through a microscope and deal with its associated poor ergonomics, and this can have a strong impact on the quality of the procedures. In addition, the laser beam is directed from a comparatively large range (400mm), resulting in accuracy and consistency problems, and requiring extensive surgeon training. In this multidisciplinary project a redesign of this surgical setup is proposed to create an advanced augmented micro-surgical system through research and development of real-time cancer tissue imaging, surgeon-machine interfaces, assistive teleoperation, intelligent (cognitive) safety systems, and augmented-reality. Furthermore, research and development of new endoscopic tools and precision micro-robotic end effectors will allow relocating the laser actuator closer to the surgical site. This will allow unprecedented levels of accessibility and precision, while the surgeon will operate in a more ergonomic, information-rich, and assistive environment. The outcomes of the project will be improved quality, safety, and effectiveness in laser phonomicrosurgery, enabling total tumour removal with minimal damage to healthy tissue. The research efforts herein will generate new knowledge in the design and control of medical micro-mechatronic devices; cancer tissue imaging; assistive teleoperation in medicine; physician-robot interfaces; and cognitive computer vision. These technological advances will pave the way towards new and safer minimally invasive laser microsurgeries, leading to a significantly enhanced capacity for cancer treatment in general.

Atomic clocks provide enhanced accuracy, stability, and timing precision compared to quartz-based technologies. However, the size and power consumption of existing atomic clocks far exceeds that those of quartz-based clocks, not preventing their deployment in portable applications.\nThe goal of the MAC-TFC proposal is to develop and demonstrate all the necessary technology to achieve an ultra-miniaturised, low-power an ultra-miniaturised caesium atomic clock, presenting a short-term stability of 5x10-11 over 1 hour while operating on the power of an AA battery, with less than 200 mW power consumption.\nPhased technology development approaches are planned. The first phase focuses on establishing theoretical limits of MEMS atomic clocks and demonstrating practical design and fabrication feasibilities, optimizing the performances of atomic resonator. Then, the second phase of proposal aims at demonstrating and developing the technologies of the building blocks for the miniaturized clock including a fully customised semiconductor laser, an innovative approach of filing the clock cell with alkali vapour and a low-power ASIC for the analog Radio Frequency (RF) electronics. The third phase is concentrated on the final chip-level integration and package of two alternative prototypes of MEMS atomic clock using LTCC technology. The physics package includes a micromachined cell with well controlled alkali vapour, a semiconductor laser , collimatting/polarizing microoptical elements and a photodetector. Finally, a fourth phase is devoted to the testing the final assembly of the physics package together with the developed electronics, as well as setting the basis for technology transfer and pre-industrialisation for potential applications.\nTo this aim, MAC-TFC brings together a consortium made of 4 major academic institutions (UFC, UniNE, WUT, UUlm), 2 research institutes ( VTT, CEA) and 3 industrial partners, SAES, ASU, OSA.
