Ukraine has a proud heritage in aeronautics dating from the Soviet era. It is one of the few countries in the world to have research, engineering and production capabilities across a wide range of aeronautics technologies. Despite these strengths, the participation of Ukrainian aeronautics actors in the ECs research framework programmes is very low (e.g. only 4 contracts were won under FP6-AEROSPACE). Consequently, the main aim of AERO-UKRAINE is to facilitate research co-operation between aeronautics actors from the EU and Ukraine. The project will achieve this via a range of activities: 1. Assessing and publicising the aeronautics collaboration potential between the EU and Ukraine. This involves mapping the Ukrainian aeronautics actors; reporting on opportunities for Ukrainian aeronautics actors in the EU; and production of a White Paper on aeronautics R&D in the Ukraine; 2. Raising awareness and understanding of EU aeronautics collaborative research. On the one side, this involves organising FP7 aeronautics events in Ukraine that combine awareness-raising, training and networking with EU aeronautics actors. On the other side, it involves Ukrainian aeronautics actors presenting their aeronautics research at aeronautics events in the EU; 3. Supporting participation in FP7 aeronautics research. This involves establishing an FP7 Aeronautics NCP in Ukraine and supporting Ukrainian aeronautics organisations to join consortia preparing FP7 research proposals. AERO-UKRAINEs measurable results include: a. White Paper on aeronautics R&D in the Ukraine; b. Website and publicly available information about 50\ aeronautics actors in Ukraine; c. Organisation of 2 FP7 aeronautics events in Ukraine; d. Participation in 3 aeronautics events in the EU; e. Establishment of an FP7 Aeronautics NCP in Ukraine; f. Support to 6\ Ukrainian aeronautics actors to join consortia preparing FP7 research proposals; g. Organisation of final dissemination conference in Kiev.

A maximum-likelihood method for estimating hyperspectral sensors random noise components, both dependent and independent from the signal, is proposed. A hyperspectral image is locally jointly processed in the spatial and spectral dimensions within a multicomponent scanning window (MSW), as small as 7 × 7 × 7 spatial-spectral pixels. Each MSW is regarded as an additive mixture of spectrally correlated fractal Brownian motion (fBm)-samples and random noise. The main advantage of the proposed method is its ability to accurately estimate band noise variances locally by using spatial and spectral texture correlations from a single textural MSW. For each spectral band, both additive and signal-dependent band noise components are estimated by linear fit of local noise variances obtained from many MSWs distributed over the whole band intensity range. CRLB-based analysis of the estimator performance shows that a good compromise is to jointly process seven adjacent spectral bands. The proposed method performance is assessed first on synthetic fBm-data and on real images with synthesized noise. Finally, four different AVIRIS datasets from 1997 flying season are considered. Good coincidence between additive and signal-dependent AVIRIS random noise components estimates obtained by our method and the estimates retrieved from AVIRIS calibration data is demonstrated. These experiments suggest that it is worth taking into account noise signal-dependency hypothesis for processing AVIRIS data. © 2011 IEEE.

Aeronautics is a key asset for the future of Europe, but nowadays the industry has to face the challenge of More Affordable, Safer, Cleaner and Quieter while at the same time accounting for a demand that will triple over the next 20 years. WASIS project aims to rise to this challenge with the development of a composite fuselage structure based on the lattice stiffening concept, optimizing geometrical and mass properties of transition zones of fuselage structural joints. Project overall concept is focused on simultaneous meeting environmental demands and rising safety coupled with design and manufacturing cost-efficiency improvement. The lattice approach allows composites to obtain more efficient mechanical behaviour, reducing weight and optimizing structure performance, which will be proved by comparative simulations against other approaches. This will be combined with specially designed semi-loop and micro-pin joining elements to provide the ability of innovative non-regular lattice structure manufacturing, save aircraft weight, avoid fuselage section weakening due to cutting reinforcement fibres. Furthermore, the structure will also be developed to better withstand worst situation loadings, assessing safety through the large adoption of simulation and virtual testing from the very first design stages to analyze explosions and material damping. Developed innovative fuselage section design will be merged with high-productive filament winding technology to reduce manufacturing costs and time, and samples will be manufactured in order to prove how the different concepts fit together. Complete testing of the samples will be applied to prove the wafer approach. As a result of this project integrated approach sufficient fuselage weight savings, manufacturing cost/time efficiency and safety increasing are to be achieved.

The overall aim of the AERO-UA project is to stimulate aviation research collaboration between the EU and Ukraine through strategic and targeted support. AERO-UA is focused solely on Ukraine, because the country has a huge aerospace potential but a low level of aviation research collaboration with the EU. Ukraines aerospace sector spans the full spectrum of systems and components development and production with OEMs, Tier 1 and 2 suppliers, aeroengine manufacturers, control systems manufacturers, R&D institutions, aeronautic universities, and SMEs. This is also reflected in the sectors important contributor to the countrys economy (e.g. aircraft production of 1,9 billion in 2011). Ukrainian aerospace organisations possess unique know-how that can help Europe address the challenges identified in the ACARE SRIA / Flightpath 2050 Report. Furthermore, following the signing of the Agreement for the Association of Ukraine to Horizon 2020 in March 2015, Ukrainian organisations are eligible to participate in Clean Sky 2 and H2020 Transport on the same funding terms as those from EU member states. Equally, genuine commercial opportunities exist for European aviation organisations to help modernise Ukraines aerospace sector. The AERO-UA project will achieve its overall aim via four high-level objectives: 1. Identifying the barriers to increased EU-UA aviation research collaboration; 2. Providing strategic support to EU-UA aviation research collaboration; 3. Supporting EU-UA aviation research knowledge transfer pilot projects; and 4. Organising awareness-raising and networking between EU-UA stakeholders. The AERO-UA consortium is comprised of key EU and UA aviation organisations that will implement WPs closely mapped to the high-level objectives. The consortium will be supported by an Advisory Board involving Airbus, DLR, Min. Education and Science of Ukraine, Ukrainian State Air Traffic Services Enterprise and retired Director of EADS Jean-Pierre Barthlemy.

Aviation is a vital industrial sector of Europes society and economy. For several historical reasons the economic activities in this field are unevenly distributed across Europe. Statistics show that also the R&D effort, which always comes along with the aviation, mirrors this allocation. On one hand, there are countries and regions featuring low involvement in aviation research and also low participation in the EU Framework Programmes; on the other some regions are heavily involved in aviation R&D and are origin of wealth and prosperity. RADIAN is a multi-step project which intends to overcome this misbalance by identification of barriers for international collaboration in aviation research at EU level and by subsequent development and verification of solutions and measures on level of the European regions. The initial step is to assess the impact of regional, national and international environment on aviation actors. An impact is considered to become a barrier in case it has a detrimental nature or significantly differs from the pan-European average. By systematically comparing single impact scenarios for various actors located in different European regions, barriers for cooperation will be identified. Having this verified knowledge, 12 target regions are identified to derive, verify and execute tailored activity plans aiming at the enhancement of the actors ability to cooperate by reducing the disadvantageous impact or by the advancement of actors own assets, knowledge and abilities. Another field of work of RADIAN is a self-sustaining collaboration platform which acts as a host for transnational exchange. The platform aims at becoming a live portal, for providing personalised information related to the users interests such as open calls, available funding schemes, recent advancements etc.

A problem of unknown signal shape estimation in noise is considered. Combined bispectrum-filtering technique is proposed for signal waveform restoration by using higher-order spectrum properties in combination with linear or nonlinear digital filtering. Numerical simulation results demonstrating reconstruction of unknown signal waveform from an observed set of noisy realizations are represented. It is shown that combined signal processing strategy contained bispectrum-based signal shape reconstruction and nonlinear/linear filtering procedures provides better noise suppression in comparison to common types of bispectral, nonlinear and linear filters. © 2013 by Begell House, Inc.
