Smart Specialisation in EU and Chile, challenges and opportunities. Towards a transcontinental policy learning dialogue methodology.

The Smart Specialisation approach is being an inspiratory driver of regional innovation not only within the European Union but beyond. This paper elaborates on the Policy Learning Dialogue: Smart Specialisation in EU and Chile which took place at the Joint Research Centre, Seville (21st November 2016). The article showcases policy reflections and outcomes derived from a fruitful discussion between practitioners of regional innovation strategies in EU and Chile, smart specialisation platform staff and experts. This policy dialogue was part of the activities carried out by the smart specialisation platform aiming at providing evidence-based support to policy makers and stakeholders of smart specialisation through common reflections focused on cooperation dynamics and joint learning.JRC.B.3-Territorial Developmen

Lunar Polar Coring Lander

Plans to build a lunar base are presently being studied with a number of considerations. One of the most important considerations is qualifying the presence of water on the Moon. The existence of water on the Moon implies that future lunar settlements may be able to use this resource to produce things such as drinking water and rocket fuel. Due to the very high cost of transporting these materials to the Moon, in situ production could save billions of dollars in operating costs of the lunar base. Scientists have suggested that the polar regions of the Moon may contain some amounts of water ice in the regolith. Six possible mission scenarios are suggested which would allow lunar polar soil samples to be collected for analysis. The options presented are: remote sensing satellite, two unmanned robotic lunar coring missions (one is a sample return and one is a data return only), two combined manned and robotic polar coring missions, and one fully manned core retrieval mission. One of the combined manned and robotic missions has been singled out for detailed analysis. This mission proposes sending at least three unmanned robotic landers to the lunar pole to take core samples as deep as 15 meters. Upon successful completion of the coring operations, a manned mission would be sent to retrieve the samples and perform extensive experiments of the polar region. Man's first step in returning to the Moon is recommended to investigate the issue of lunar polar water. The potential benefits of lunar water more than warrant sending either astronauts, robots or both to the Moon before any permanent facility is constructed

Atmospheric effects on the risetime and waveshape of sonic booms

Accurate prediction of human response to sonic booms from proposed HSCT aircraft depends on a knowledge of the waveshape and risetime of the boom at the ground. In previous work, we have developed a numerical technique to predict the combined effects of molecular absorption and finite wave distortion on the sonic boom as it propagates from the aircraft to the top of the turbulent boundary layer. We have more recently developed a scattering center based model to calculate the effects of turbulence on the sonic boom waveform as it propagates through this boundary layer. Calculations have been performed using single scales of turbulence and compared to measurements at Edwards AFB in the late 1960's. A model of the atmosphere involving two scales each for convective and mechanical turbulence has been developed and fit to meteorological data collected during JAPE 2. Scattering calculations employing this model underpredict the number of unperturbed waveforms. In order to develop a more realistic model of the atmosphere, the JAPE 2 meteorological data has been fit to a von Karman spectrum. Results of scattering using this multi-scale model will be presented. The combination of finite wave effects with turbulent scattering predictions includes the principal effects of the atmosphere on the sonic boom from the HSCT

European Parliament Preparatory Action: "Actual and desired state of the economic potential in regions outside the Greek capital Athens" Final Report

This is the final report of the European Parliament Preparatory Action: "Actual and desired state of the economic potential in regions outside the Greek capital Athens" (hereafter Preparatory Action or PA). It reviews the key activities of this preparatory action, its impacts, the remaining barriers to RIS3 implementation and presents a perspective on the way forward. Providing hands-on support to the refinement and implementation of the RIS3 strategy in the Greek Region of Eastern Macedonia and Thrace (REMTh) has entailed the following activities: • Mutual learning: this has at core element of the preparatory action, and has offered a unique opportunity to all the stakeholders involved to share experiences and build a common understanding of RIS3, its potential and the real challenges to its implementation. • Optimisation of the Entrepreneurial Discovery Process (EDP) – the design, implementation and adaptation of a systematic participatory methodology for the EDP, centred on thematic focus groups. These events enabled the generation and articulation of innovation ideas and initiated the first necessary steps towards concrete projects. • Capacity building - two dedicated working groups were organised: one centred on issues of human resources mobility and one on RIS3 governance. Relevant stakeholders, under the guidance of an expert, discussed and formulated plans on how to tackle the different challenges at stake. • Identification of bottlenecks and systemic failures in RIS3 implementation - the region has good potential for diversification, but faces a wide set of legal and administrative barriers, which need to be addressed to enable the allocation of structural funds and other resources to support RIS3 implementation in an optimal way. • Communication and codification of activities - with the aim of replicating or adapting the activities of the preparatory action and the emerging learning opportunities for other regions, outcomes of all the events have been published on-line, as have methodological guidelines for the EDP process. Furthermore, further publications from these activities are foreseen in the near future. • Supporting tools for internationalisation and collaboration. The preparatory action has developed a set of online resources that aim at guiding the region in increasing its international outlook to RIS3 and its collaboration between research and industry. The Preparatory Action generated some very concrete impacts on the regions, among which the main ones are: • The mobilisation of a critical mass of researchers and business people (600+ people), which actively participated to the EDP focus groups and PDL events. This bottom-up process has increased mutual trust, created a 'momentum' in initiating change and increased the understanding of what RIS3 can contribute to this change. • The appreciation of networking and research-business collaboration across stakeholders and especially between research and business. Indeed, some informal networks have been organised, for instance in the wine and marble sector. • The creation of an action plan for both RIS3 governance and mobility of human resources. • Both the Managing Authority and regional stakeholders have better access to international counterparts, both in governance of RIS3 and in performing research and innovation. • The project has also determined a shift in perception as far as the European Commission is concerned, which is now perceived more as a collaborator. • The PA has stimulated and accelerated a discussion between the EC, regional and national authorities which has help to clarify – for the whole country – several aspects of RIS3 and Structural Funds. • The preparatory action has significantly influenced the way to design and implement the development strategy for the Region by engaging all relevant stakeholders from the outset.JRC.J.2-Knowledge for Growt

Performances comparées d'une roue Francis modèle réduit et d'une roue prototype de même dimension

Dans le même modèle réduit de nq = 77 on essaye successivement une roue de laboratoire en matière plastique armée de diamètre 408 mm et une roue industrielle de meme diamètre en bronze d'aluminium. Cette roue industrielle reste d'abord brute de fonderie. Puis elle est usinée par meulage et enfin sa rugosite est modifiée. Les tests comparatifs portent sur le rendement, la cavitation et le sondage de l ' écoulement à la sortie. Les conclusions portent sur la comparaison entre l'évolution des performances selon le degré de finition et le coût de ces finitions, et une application de la méthode de transposition "OSTERWALDER- HIPPE" est tentée

Lift nets is one of the fishing gear which operate at the night.  This fishing gear are using light as a aids to attract fish into the fishing area.  Research on the use of LED lights in water on lift nets is carried out in Tateli Weru Waters, with the aim to see how the effect of using different color underwater LED lights on anchovy catches (Stolephorus commersonii), and knowing the amount of anchovy (Stolephorus commersonii) catch on lift net using the experimental method, where data is analyzed using Completely Randomized Block Design (RCBD), and continued by Least Significant Difference test (LSD).  Trial of anchovy fishing (Stolephorus commersonii) was conducted in December 2018 for 10 days by operating boat lift nets using green, blue and green-blue LED lights.  The results showed that the use of LED light colors in blue water had a very significant effect on the amount of anchovy catch (Stolephorus comersonii) compared to to the color of LED lights in green-blue and green water.  Whereas the use of LED light colors in blue-green water with green is not statistically significantly different from the amount of anchovy caught (Stolephorus comersonii).ABSTRAKBagan merupakan salah satu alat penangkapan ikan yang dioperasikan pada malam hari.  Alat tangkap ini menggunakan cahaya lampu sebagai alat bantu untuk menarik ikan masuk ke dalam area penangkapan.  Penelitian mengenai penggunaan lampu LED dalam air pada bagan dilakukan di Perairan Tateli Weru, dengan tujuan untuk melihat bagaimana pengaruh penggunaan lampu LED bawah air dengan warna yang berbeda terhadap hasil tangkapan ikan teri (Stolephorus commersonii), serta mengetahui jumlah hasil tangkapan ikan teri (Stolephorus commersonii) pada bagan dengan menggunakan metode eksperimental, dimana data dianalisis dengan menggunakan  Rancangan Acak Kelompok (RAK) dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT).  Uji coba penangkapan ikan teri (Stolephorus commersonii) dilakukan pada bulan Desember 2018 selama 10 hari dengan mengoperasikan bagan apung menggunakan lampu LED hijau, biru dan hijau-biru.  Hasil penelitian menunjukkan bahwa penggunaan warna lampu LED dalam air biru memberikan pengaruh yang sangat nyata terhadap jumlah hasil tangkapan ikan teri (Stolephorus comersonii) dibandingkan warna lampu LED dalam air hijau-biru dan hijau.  Sedangkan antara penggunaan warna lampu LED dalam air hijau-biru dengan hijau secara statistik tidak berbeda nyata terhadap jumlah hasil tangkapan ikan teri (Stolephorus comersonii)

A Multifractal approach for sun glint in medium resolution satelite imagery

International audienceSun glint, the specular reflection of sunlight off the ocean surface and into the satellite sensor, compromises data processing in ocean remote sensing imagery. Several correcting algorithms and models have been developed to improve satellite high-level products quality in glint-contaminated areas. Some rely on radiative transfer equations and others on in-scene information analysis, but most of these methods are based on an estimation of the sun glint contribution in terms of radiance. In this paper, we introduce a new approach for sun glint study in medium resolution satellite images, derived from multiscale/multifractal techniques. Since sun glint introduces long range effects and occurs at a scale much smaller than pixel dimensions, multiscale techniques are well suited to analyse such complex signals and are able to extract features related to the oceanic flows. First, we apply a multifractal decomposition scheme to generate the signal singularity exponents and retrieve the so-called "most singular manifold". Using the main streamlines of the signal, we compute a reduced image containing the same multiscale structures as the original one but a naive distribution of the gradient. We will then show that the correlation between the original image and the reduced one, also known as the source field in the microcanonical multiscale formalism, displays a signature related to the presence of sun glint

Comparison of different blood pressure indices for the prediction of prevalent diabetic nephropathy in a sub-Saharan African population with type 2 diabetes

Background: The association between blood pressure (BP) and diabetic kidney diseases in Africans has been less well investigated. We assessed and compared the strength of the association and discriminatory capability of systolic (SBP), diastolic (DBP) BP, pulse pressure (PP) and mean arterial blood pressure (MAP) for nephropathy risk in sub-Saharan Africans with type 2 diabetes. Methods: Participants were 420 consecutive individuals (49% men) with type 2 diabetes receiving chronic care in two main referral centres in the two major cities of Cameroon. Logistic regression models were used to compute the odd ratio (OR) and 95% confidence interval (95% CI) for a standard deviation (SD) higher level of SBP (25 mmHg), DBP (13), PP (18) and MAP (16) with nephropathy risk. Discrimination was assessed and compared with c-statistics and relative integrated discrimination improvement (RIDI, %). Results: The adjusted OR (95% CI) for nephropathy with each SD higher BP variable were: 1.45 (1.15-1.84) for SBP, 1.33 (1.06-1.66) for DBP, 1.35 (1.06-1.71) for PP and 1.42 (1.13-1.78) for MAP. C-statistic comparison showed no difference in discrimination of models with each of the BP variables (p-values B 0.69 for c-statistics comparison). However, RIDI statistic always showed and enhancement in models discrimination when other BP variables were replaced with SBP, although such an enhancement was marginal for MAP. Using BP combination modestly improved models? discrimination. Conclusion: SBP was the best predictor of prevalent nephropathy in this population, while DBP was the less effective. This may have implication for kidney disease risk stratification and protection
