Learning Layers develops a set of modular and flexible technological layers for supporting workplace practices in SMEs that unlock peer production and scaffold learning in networks of SMEs, thereby bridging the gap between scaling and adaptation to personal needs. By building on recent advances in contextualized learning, these layers provide a meaningful learning context when people interact with people, digital and physical artefacts for their informal learning, thus making learning faster and more effective. Building on mobile learning research, we situate learning into physical work places and practices to support situated, faster and more meaningful learning. Learning Layers provide a shared conceptual foundation independent of the tools people use and the context they are in. Learning Layers are based on a common light-weight, distributed infrastructure that allows for fast and flexible deployment in highly distributed and dynamic settings. We apply these technologies in sectors that have been particularly hesitant to take up learning technologies, i.e. health care and building and construction. Involving two representative and large-scale regional SME clusters allows us to involve end users in co-design of the system and later scale up the approach to more than 1,000 learners within 4 years. By inviting a larger set of stakeholders to adapt and build on our solutions and through research in sustainable business training models, the project will generate significant impact by boosting the ability of regional innovation systems to adapt to change and thereby remain competitive, on the individual, organisational and regional level. We demonstrate the impact in the two chosen sectors, but widen the scope to other sectors and regions towards the end of the project.

EmployID aims to support and facilitate the learning process of Public Employment Services (PES) practitioners in their professional identity transformation process. To perform successfully in their job they need to acquire a set of new and transversal skills, develop additional competencies, as well as embed a professional culture of continuous improvement. EmployID will offer efficient use of technologies to provide advanced coaching, reflection and networking services. Based on adult learning theories, the project focuses on technology developments that make facilitation services for professional identity transformation cost-effective and sustainable by empowering the individual to engage in peer learning and facilitation. This will include (1) e-coaching tools that make coaching processes more efficient and enables peers to develop coaching skills, (2) reflection tools that integrate into coaching processes and support on-going conversation across contexts, (3) novel networking and facilitation tools that support individuals in becoming effective facilitators for the learning of others, and (4) flexible scorecard visualizations as a form of workplace learning analytics, partially fed by data collected from the user activities and feedback. These new tools will integrate into existing learning and training infrastructures, such as existing LMS. Privacy aspects will be addressed carefully by appropriate technical and organizational means. The EmployID framework will help PES practitioners to become self-directed learners and competent in their job counselling and PES organisations in effectively managing the up-skilling of their staff. A comprehensive and empirically validated indicator framework for PES organizations adaptable to their needs will support the development of a performance improvement culture. Our holistic approach is targeting professional identity transformation on an individual, network and organisational level.

Membrane bioreactor (MBR) technology is regarded as key element of advanced wastewater reclamation and reuse schemes and can considerably contribute to sustainable water management. MBR technology is used for wastewater treatment and reuse in municipal, agricultural and a variety of industrial sectors in Europe and MENA. The market pull, in the context of this NMP call, is the increasing demand for clean water complying with the strict European and MENA regulations. The European growing MBR market is dominated by two suppliers from Canada and Japan. Although, the European scientific community is strong in R&D, its expertise remains fragmented and lacks organization and communication within Europe. Despite the fact that the technical feasibility of this technology has been demonstrated through a large number of small and large scale applications, membrane fouling is regarded as an important bottleneck for further development. It is the main limitation to faster development of this process, particularly when it leads to flux losses that cleaning cannot restore. The objective of the BioNexGen project is therefore to develop a new class of functional low fouling membranes for membrane bioreactor technology with high and constant water flux (25 l/m2/h) and high rejection of organic pollutants with low molecular weight (down to 300 Da). The consortium consisting of European and MENA partners will develop a novel single step NF MBR operated with low energy consumption due to less aeration needed (0.2 Nm3/m2/h). Small footprint, flexible design, and automated operation make it ideal for localized, decentralized wastewater treatment and recycling in the European and MENA countries. Successful delivery will have a major impact on the competitiveness of the SME partners in the project and the European and MENA MBR market. Furthermore it will significantly contribute to scientific and technological cooperation between European and MENA countries in the provision of safe water.

The objective of INTUITEL is to enhance state-of-the-art e-learning content and Learning Management Systems (LMS) with features that so far have been provided only by human tutors. An INTUITEL-enabled system constitutes an integrated learning environment that configures itself in response to any learner, monitors his/her progress and behaviour, combines these data with pedagogical and methodological knowledge and then by automated reasoning deduces optimal guidance and feedback. The deductive process may include the current learner performance, the daily learning attitude and emotional setting of the learner, personal aspects like gender, culture and age as well as environmental aspects like available communication bandwidth, ambient noise level, screen size and type of access device. INTUITEL therefore will be a step towards a global learning cloud, where personalized technology-enhanced learning is available for any person at any place, with any access device and under any external condition, including mobile learning scenarios. In INTUITEL, learning goals will be defined according to the desired competency, which will be mapped to the available content. At the same time, high flexibility to choose a learning pathway is maintained by offering system driven and learner directed navigation tools, thereby increasing the empowerment of teachers and learners and fostering the acquisition of methodological knowledge. By interpreting the learners responses INTUITEL will automatically determine his/her position in a cognitive model for the particular learning content. The INTUITEL-enabled LMS then plays the role of a pedagogically skilled teacher, transparently guiding the learner towards the required competencies. Particular emphasis will be put on a widespread dissemination of INTUITEL results across the e-learning industry as well as in schools, universities and to other educational key players in collaboration with a major e-learning conference.

VicInAqua will follow an integrated approach in order to develop a sustainable combined sanitation and recirculating aquaculture system (RAS) for wastewater treatment and reuse in agriculture in the Victoria Lake Basin area. In this decentralized integrated treatment system wastewater from households and fish processing industry as well as RAS production water will radically reduce stress on the sensitive ecosystems of the Lake Victoria and will contribute to food and health security. It will be operated fully autonomous powered by renewable energies (PV, biogas). The RAS will particularly produce high quality fingerlings of the local fish species to supply the pond aquaculture of the area with stocking material. The innovative core idea of the project is to develop and test new technologies which enable the integration of sanitation with the aquaculture in a sustainable manner. The core of the project concept is to develop and test a novel self-cleaning water filters which consist of a highly efficient particle filter as well as a membrane bioreactor (MBR) as principal treatment unit within a combined treatment system where the nutrient rich effluent water will be used for agricultural irrigation. the surplus sludge from both filter systems will be co-digested with agricultural waste and local water hyacinth to produce biogas. The overall concept will promote sound approaches to water management for agriculture, taking into consideration broader socio-economic factors and also fomenting job creation and greater gender balance in decision-making. The pursued approach will be perfectly in line with the strategic guidelines of the Rio\20 and the post-2015 development framework.

The vision of I-RAMP is to enable the European industry towards smart manufacturing systems in conventional production. The project aims at creating innovative solutions in order to improve the competitiveness for this industry sector. This goal will be reached by a new concept for fast and optimized ramp-up and operation of production lines with heterogeneous devices. By this, significant reduction of time and efforts during the setup and re-configuration of production will be reached. At the same time, production costs will be reduced by increasing the efficiency of manu-facturing. This challenge will be tackled by the introduction of the so called NETDEVs. This new kind of agent-based production devices is equipped with standardized interfaces and standardized communication protocols as well as self-descriptive capabilities. Furthermore, NETDEVs are able to optimize themselves to varying setup of production and production conditions by negotiating with each other. A plug-in concept of different models allow for easy extension of NETDEVs for maintenance and re-use purposes. By revealing hidden features I-RAMP technology is able to multiply the usability of conventional devices. The I-RAMP concept covers also new approaches for the smart introduction of intelligent sensors and actuators as they play a significant role in future smart factories. Such systems will be equipped with standardized interfaces and advanced communication skills in order to improve plug&work. The holistic concept of I-RAMP for enabling future smart factories is completed by the introduction of knowledge-based modules for Manufacturing Execution Systems. The additional features of the I-RAMP approach allow for increasing flexibility and fault-tolerance during production. Having I-RAMP technology available, a significant step towards plug&produce technology as well as better modularity, maintainability and reusability will be done.

The vision of ReBORN is to demonstrate strategies and technologies that support a new paradigm for re-use of production equipment in old, renewed and new factories; maximizing the efficiency of this re-use and making the factory design process much easier and straight forward, shortening ramp-up times and increasing production efficiency and flexibility. This paradigm will give new life to decommissioned production systems and equipment, making it possible their reborn in new production lines. Integration of ReBORN results will extend production equipment life cycle and contribute to economic and environmental sustainability of production systems without jeopardizing European machinery industry. This new modular production equipment will be re-used between production systems but will require servicing and upgrading. For that European machinery industry will move from an equipment-based business to a value added business, where equipment servicing and equipment knowledge are main business drivers. The proposed paradigm builds on self-aware and knowledge-based equipment that need functionalities to collect and manage information regarding their capabilities and their evolution over time, maintenance, upgrade or refurbishment operations over it lifetime; and information of use and wear. To do so, versatile and modular, task-driven plug&produce devices, with built-in capabilities for self-assessment and optimal re-use will be implemented, along with strategies for their re-use and models for factory layout design and adaptive configuration. ReBORN will demonstrate the technologies for intelligent repair, upgrade and re-use of equipment, the (re-)design of factory layouts and flexible & adaptable production on shopfloor within several industrial demonstration scenarios. Having ReBORN technology available, significant reduced efforts when setting-up and ramping-up production systems will be achieved and a significant step towards 100% re-use will be done.

Detailed radar and ultrasonic measurements were made from a mobile platform underneath the Laufenmühle viaduct. Credit: IONYS/KIT The Waldbahn railway line near Welzheim is one of the most beautiful railway lines in South Germany and listed as a monument. Its viaducts, however, require restoration. The 100-year-old Laufenmühle viaduct, for instance, exhibits major damage, such as cracks in the reinforced concrete. If the viaduct was restored with standard state-of-the-art methods, the expenditure and costs would be enormous and the monument character would be endangered. The KIT Innovation Hub "Prevention in Construction" now succeeded in bringing together the right partners and in developing a customized approach to sustainable repair of the viaduct. "Construction of the Laufenmühle viaduct 100 years ago was a technical masterpiece of civil engineers. Now, engineers also break new ground in the restoration of the damaged concrete pillars and arches," explains Professor Andreas Gerdes, Scientific Director of the KIT Innovation Hub. Based on today's regulations and building data collected, a support construction of 30 to 50 cm thick concrete arches had been envisaged underneath the viaduct. However, this would have changed the appearance of the bridge. "The associated expenditure and costs would have been enormous," Gerdes points out. "Instead, we used modern scientific methods to improve the database and to adapt the repair concept to the viaduct without damaging its basic structure." Use of modern scientific methods for historic constructions results in customized options for the preservation of monuments, in particular for early reinforced concrete constructions. "By ultrasonic and building radar measurements, every centimeter of the viaduct was examined down to a depth of 50 to 70 cm and documented. The damaged points were identified and assessed," Gerdes reports. Cooperation between IONYS AG, a spinoff of KIT, and the Patitz engineering office produced a detailed picture of the damage of the viaduct. With these data, the Rothenhöfer engineering office carried out innovative computations and provided the static basis for repair. Such detailed recording and analysis of data facilitates sustainable planning for municipalities as the building owners. Resources can be used optimally and a customized repair concept can be implemented. For the Laufenmühle viaduct, this means that cement suspensions will be injected specifically into the damaged areas of the arched bridge. "In this way, the original appearance of the Laufenmühle viaduct will be preserved," Gerdes says. "And, in addition, restoration costs are reduced considerably." Now, the city of Welzheim only has to afford an amount of EUR 2.2 million instead of 3.5 million for the originally planned restoration. At the same time, further operation of the railway line as a tourist attraction will be ensured. Parallel to operation, restoration is planned to be completed by summer 2017. The historic Waldbahn railway line between Rudersberg and Welzheim consists of three viaducts, the Laufenmühle viaduct, the Strümpfelbach viaduct, and the Igelsbach viaduct. The ensemble of nearly 23 km in length is listed as a monument. In particular, the Laufenmühle viaduct is considered a major construction of early railway building and has become a landmark. Since 2010, the railway line has been operated as a tourist attraction and developed to a major infrastructure for the spa of Welzheim. The restoration method was developed by the KIT Innovation Hub "Prevention in Construction." The KIT Hub wants to bring together the actors of the complete innovation and value-added chain, in particular small and medium-sized enterprises. Competences are to be pooled and sustainable solutions are to be developed for the preservation of modern as well as historic technical infrastructure buildings. All these goals were met when planning the repair of the Laufenmühle viaduct: Scientists of KIT, IONYS AG - a spinoff of KIT and Karlsruhe University of Applied Sciences, and the engineering offices Rothenhöfer and Patitz in Karlsruhe jointly developed a sustainable solution that is in the interest of all parties.

Materials in which the yield point phenomenon occurs exhibit a characteristic drop in the stress-strain curve at the end of the elastic (or mainly elastic) region. In most cases the subsequent plastic deformation takes place locally in deformation bands, often termed Lüders bands. Although first described more than 150 years ago, the yield point phenomenon is not yet fully understood. In this paper, a new and simple macromechanical model is presented to explain the yield point phenomenon. It is based on three major points: (i) a realistic or true upper yield point, (ii) typical strain-hardening behaviour common to many materials and (iii) the triaxiality of the stress state that necessarily has to develop at the Lüders front and that determines the stress level at the lower yield strength. The model is evaluated by experimental, analytical and numerical evidence. Combining all evidence, the model basically describes the yield point phenomenon correctly. It may also be applied to related strain-softening phenomena and it explains the comparatively low ductility of some nanocrystalline materials. © 2012 Acta Materialia Inc. Published by Elsevier Ltd.
