Phased microphone arrays are used in a variety of applications for the estimation of acoustic source location and spectra. The popular conventional delay-and-sum beamforming methods used with such arrays suffer from inaccurate estimations of absolute source levels and in some cases also from low resolution. Deconvolution approaches such as DAMAS have better performance, but require high computational effort. A fast beamforming method is proposed that can be used in conjunction with a phased microphone array in applications with focus on the correct quantitative estimation of acoustic source spectra. This method bases on an eigenvalue decomposition of the cross spectral matrix of microphone signals and uses the eigenvalues from the signal subspace to estimate absolute source levels. The theoretical basis of the method is discussed together with an assessment of the quality of the estimation. Experimental tests using a loudspeaker setup and an airfoil trailing edge noise setup in an aeroacoustic wind tunnel show that the proposed method is robust and leads to reliable quantitative results. © 2009 Elsevier Ltd.

A liquid reaction route and a solid reaction route are developed to fabricate dense γ-TiAl foils and sheets. Sheets were prepared by a one-stage annealing of Ti-Al sandwiches made from two Ti sheets either side of one Al sheet. While annealing above the melting point of TiAl 3 results in an inhomogeneous sheet thickness and Al content, a sheet with homogeneous thickness and Al distribution is obtained after annealing below this temperature. Dense γ-TiAl foils were prepared by a two-stage annealing of diffusion bonded sandwiches with aluminum as the outer layer. Depending on the annealing temperature, near-γ, layered γ-α 2, layered duplex, or lamellar microstructure can be obtained. The first-stage annealing is below the melting point of aluminum and the second-stage annealing temperature is above 1000 °C. A corrugated γ-TiAl foil was prepared by diffusion welding, corrugation at room temperature and final two-stage reactive diffusion. The reaction mechanism involved in both routes, such as the porous TiAl 3 layer formation, the consolidation of the porous TiAl 3 layer, the formation of Al inclusions, voids and an irregular TiAl 3 layer in the first-stage annealing, and the disappearance of voids and formation of surface cracks in the second-stage annealing was investigated and discussed. © 2010 Elsevier Ltd.

The overall goal of ClimeFish is to help ensure that the increase in seafood production comes in areas and for species where there is a potential for sustainable growth, given the expected developments in climate, thus contributing to robust employment and sustainable development of rural and coastal communities. The underlying biological models are based on single species distribution and production, as well as multispecies interactions. Forecasting models will provide production scenarios that will serve as input to socio-economic analysis where risks and opportunities are identified, and early warning methodologies are developed. Strategies to mitigate risk and utilize opportunities will be identified in co-creation with stakeholders, and will serve to strengthen the scientific advice, to improve long term production planning and the policy making process. ClimeFish will address 3 production sectors through 16 case studies involving 25 species, and study the predicted effects of 3 pre-defined climate scenarios. For 7 of these cases ClimeFish will develop specific management plans (MPs) coherent with the ecosystem approach and based on a results-based scheme that will allow regulators, fishers and aquaculture operators to anticipate, prepare and adapt to climate change while minimizing economic losses and social consequences. A guideline for how to make climate-enabled MPs will be produced, and published as a low-level, voluntary European standard after a consensus-based open consultation process. As a container for the models, scenarios and MPs ClimeFish will develop the ClimeFish Decision Support Framework (DSF) which also contains the ClimeFish Decision Support System (DSS); a software application with capabilities for what-if analysis and visualization of scenarios. The presence of key international stakeholders in the project will ensure quality and relevance of the project outputs thus ensuring uptake and significant impact also after project end.

Agroforestry is the practice of deliberately integrating woody vegetation (trees or shrubs) with crop and/or animal systems to benefit from the resulting ecological and economic interactions. AGFORWARD (AGroFORestry that Will Advance Rural Development) is a four-year project, developed by 23 organisations at the forefront of agroforestry research, practice and promotion in Europe, with the goal of promoting appropriate agroforestry practices that advance sustainable rural development. The project will i) increase our understanding of existing, and new extensive and intensive agroforestry systems in Europe; ii) identify, develop and demonstrate innovations to improve the ecosystem service benefits and viability of agroforestry systems in Europe using participatory research, iii) develop better adapted designs and practices for the different soil and climatic conditions of Europe, and iv) promote the wide adoption of sustainable agroforestry systems. Successful and sustainable agroforestry practices are best developed by farmers and land owners working in partnership with researchers, extension staff, and other rural businesses. AGFORWARD will facilitate 33 participative agroforestry research and development stakeholder groups to improve the resilience of i) existing agroforestry systems of high nature and cultural value such as the dehesa and montado; and ii) olive, traditional orchard, and other high value tree systems, and the sustainability of iii) arable and iv) livestock systems with the integration of trees. Using existing bio-economic models, AGFORWARD will evaluate and adapt the innovations to improve the delivery of positive ecosystem services and business profitability at farm- and landscape-scales across Europe. By using and developing existing European fora, such as the European Agroforestry Federation, AGFORWARD will implement an informative and effective promotion programme to benefit the European economy, environment and society.

Advances in key economical and societal issues facing Europe, like transport, energy generation, climate change, or industrial, environmental and geophysical mixing processes are obstructed by the lack of understanding of turbulence. To date, models fail to explain many fundamental features of turbulence, from boundary layers and particle transport, to heat transport and turbulence in complex and quantum fluids. This has led several European countries to fund new large-scale turbulence facilities, unsurpassed in flow properties and measurement technologies. Currently these are not easily accessible to the larger EU scientific community. This inhibits the rapid advancement of research across Europe and hinders the optimal use of the resources, and their impact on the development of new advanced technologies and solutions. Recognizing this deficiency, the leading groups in turbulence research with members from 9 countries propose to form the European High-performance Infrastructures in Turbulence (EuHIT) within the Integrated Infrastructure Initiative (I3). 14 Top-notch European infrastructures agreed to provide the research community with transnational access to their facilities. Joint research activities of the consortium will innovate and explore new fundamental technologies that will ensure efficient and joint use of these research infrastructures by creating harmonised and enhanced interfaces, improving data processing methods, and optimizing the quality and increasing the quantity of the services provided to researchers from academia and industry alike. A networking and educational program will be established to foster cooperation among research infrastructures and the scientific community, to train the next generation researchers in using the most modern equipment and data analysis techniques, and thus to develop a more efficient and attractive European Research Area.
