We consider the Markov random flight X(t),t>0, in the three-dimensional Euclidean space R3 with constant finite speed c> 0 and the uniform choice of the initial and each new direction at random time instants that form a homogeneous Poisson flow of rate λ> 0. Series representations for the conditional characteristic functions of X(t) corresponding to two and three changes of direction, are obtained. Based on these results, an asymptotic formula, as t→ 0 , for the unconditional characteristic function of X(t) is derived. By inverting it, we obtain an asymptotic relation for the transition density of the process. We show that the error in this formula has the order o(t3) and, therefore, it gives a good approximation on small time intervals whose lengths depend on λ. An asymptotic formula, as t→ 0 , for the probability of being in a three-dimensional ball of radius r< ct, is also derived. Estimate of the accuracy of the approximation is analysed. © 2016, Springer Science+Business Media New York.

European manufacturing leadership has been built on the solid pillars of product innovation, high production quality and competitive cost. ICT based products and services have been instrumental in developing such competitive advantage. To reinforce such leadership European manufacturing industry, and in particular SMEs, demand specific actions to (a) bring new cutting edge ICT technology closer to manufacturing to allow assessment and take up, (b) make visible the impact of the solutions and (c) multiply the competitiveness of European industry as a result. Through the ICT Innovation for Manufacturing SMEs (I4MS) initiative, the EC is promoting a large number of application experiments for robotics (EuRoc) and simulation (FORTISSIMO, CloudFlow, CloudSME) and equipment assessment experiments for sensor (INTEFIX) and laser based applications (APPOLO, LASHARE). Application experiments target advanced robot solutions for new manufacturing applications and simulation services for engineering and manufacturing SMEs including a cloud-based service infrastructure that provides the needed high performance computing resources. Assessment experiments target innovative sensor-based equipment solutions in manufacturing and control, and innovative laser applications in manufacturing.\nI4MS-Gate is a FP7 CSA that aims at multiplying the innovation impact of more than 160 European ICT for Manufacturing Experiments planned in the I4MS Programme. I4MS-Gate also aims at amplifying the findings of two European R&D ICT road-mapping activities (Road2Fame and PathFinder). Collaborating with major European stakeholders, I4MS-Gate will deliver the reference European portal on ICT Innovation for Manufacturing SMEs (www.i4ms.eu). Through specific dissemination and coordination actions, SMEs will enjoy an integrated access to todays distributed innovation instruments, resources, networks and platforms. They will:\n1.leverage more easily on cutting edge ICT solutions\n2.reach more effectively and efficiently a large European innovation and customer base\n3.gain greater visibility and awareness about ICT services and equipment for manufacturing competitiveness improvement.\nI4MS-Gate will provide a single entry point to a European innovation ecosystem of enterprises, customers and ICT technology networks for increased supply and demand visibility of ICT innovation in manufacturing. I4MS-Gate will allow SMEs ICT providers and integrators and customers to (a) gain visibility in European markets and connect with the financial resources; e.g. open calls for experiments; to perform first of a kind technical validations and assessments of their ICT solutions. (b) gain increased awareness on new applications of robotics, sensor and laser systems and simulation solutions. (c) acquire best innovation practices in ICT for manufacturing technology take-up. (d) to understamd future ICT trends to be able to cross the innovation chasm and bring stronger ICT products into the market.

eInfrastructure in Europe has reached a mature state where the GEANT network forms a backbone on top of which a distributed computing infrastructure - the Grid - provides processing and storage services for eScience research. The South-East European eInfrastructure initiatives are committed to ensuring equal participation of the less-resourced countries of the region in European trends. SEEREN initiative has established a regional network and its GEANT connection and the SEE-GRID initiative the regional Grid. Hereby proposed SEE-GRID-SCI will leverage the SEE eInfrastructure to enable new scientific collaborations among SEE user communities. SEE-GRID-SCI will stimulate widespread integrated eInfrastructure uptake by new cross-border user groups extending over the region, fostering collaboration and providing advanced capabilities to more researchers, with an emphasis on strategic groups in seismology, meteorology and environmental protection. The initiative thus aims to have a catalytic and structuring effect on a variety of user communities that currently do not directly benefit from the available eInfrastructures. In parallel, it will enlarge the regional eInfrastructure to cater for demands of the communities: a number of new Grid clusters and countries will be added, engaging a wider range of players and expanding the provider pool. Finally, SEE-GRID-SCI will help mature and stabilise the National Grid Initiatives in the region, allowing them to join the new era of longer-term sustainable Grid infrastructure in Europe. In this context, SEE-GRID-SCI will aim to attract political and financial support for materializing the eInfrastructure vision. In longer term, SEE-GRID-SCI aspires to contribute to the stabilisation and development of South-East Europe, by easing the digital divide and stimulating eInfrastructure development and adoption by new user communities, thus enabling collaborative high-quality research across a spectrum of scientific fields.

The overall aim of the SECURE-R2I project is to reinforce cooperation with Eastern Partnership Countries (EPC) on bridging the gap between research and innovation for Horizon 2020 Societal Challenge 6. Inclusive, Innovative and Secure Societies. The research domains encompassed by Inclusive, Innovative and Secure Societies are broad. From the perspective of FP7 thematic priorities, they include ICT; Security; Nanosciences, Nanotechnologies, Materials (NMP); and Social Sciences and Humanities (SSH). These research domains also form the basis of important economic sectors in the EPC, with many potential benefits for the EU, but which also need European support to increase their exploitation. Addressing this issue, the SECURE-R2I project will assist R&D and innovation (RDI) organisations in EPC via a range of knowledge and technology transfer activities with the support of European specialists. The activities include: Networking between EPC organisations involved in RDI for Societal Challenge 6: It consists in mapping EPC RDI organisations and organising brokerage events to stimulate cooperation; Analysing the tech transfer opportunities and bottlenecks of EPC organisations involved in RDI for Societal Challenge 6: It consists in surveying these organisations and holding discussions with representatives of government, industry, government and intermediary bodies; Exchanging best practices in knowledge/technology transfer via a range of specific training courses and intensive summer schools in Europe; Twinning via R2I pilot projects: Each EPC research partner in the consortium will twin with another consortium partner who will support them to implement a bilateral R2I pilot project; Providing innovation support services to selected, high-potential EPC (and European) RDI: The activities will consist in coaching and advisory services on innovation and tech-transfer.

The proposed project aims at designing, manufacturing and building of a demonstrator for a new engine concept. The new concept replaces the usual turbine of a classical turboengine by a number of Pulse Detonation Combustors (PDC) placed on a disk that rotates under the tangential impulse provided by the exhaust jet of the PDC. The rotating disk is coupled, through a shaft, to the compressor that is placed upstream of the PDC in order to raise its inlet pressure. Two solutions will be considered for the engine propulsion: a propeller, coupled, via a gearbox, to the PDC shaft, or by using the reactive thrust of the PDC exhaust jet, directed at an optimal angle. The PDC inlet with be equipped with aerodynamic valves that control the air entrance into the PDC, thus allowing a significant increase in the detonation frequency, allowing for noise reduction and reduced dimensions. The demonstrator, consisting of a single, fixed, PDC equipped with a fuel injection and ignition system designed for the requirements of the engine concept, will be tested on an experimental facility in order to demonstrate the PDC capability to provide enough power to meet the requirements of the compressor, with sufficient reserve for powering to propel the host aircraft. The project also proposes the design and numerical simulation of the engine compressor, adapted to the requirements of the new engine, most importantly the high vibration load and oscillatory back pressure under which the compressor operates. A last objective of the project is to provide a full definition of the engine constructive solution and a numerical simulation of the flow through the engine that will allow the estimation of the engine performances. The new emerging technology is expected to provide a significant increase in the engines thermodynamic cycle maximum temperature and efficiency, a drastic reduction in its weight and specific fuel consumption, and a decrease of greenhouse gas emissions.

The behavior of an electronic subsystem in strong interaction with phonon subsystem, or quantified electromagnetic field (QEF) is discussed. In this case the correlation effect between first and second order electron-phonon interaction (or atom-QEF interaction) takes place. It is shown that the temperature dependence of two-quanta exchange between Fermi sub-system and thermal reservoir gives a nonlinear behavior of the order parameter in superconductivity and super-radiance, accompanied by an increase of the electron correlations with increasing temperature. The same effect is considered for two-quanta scattering processes, in which one quantum is absorbed and another is emitted. It is demonstrated, that the order parameter in such a system firstly increases with temperature achieving the maximal value. After that it decreases as in traditional phase transition effects. © 2010 Springer Science+Business Media, LLC.

Two types of resonance between the spontaneous emissions by two- and single photon transitions of three inverted radiators from the ensemble are proposed to accelerate the collective decay rate of the entangled photon pairs generated by the system relative the dipole-forbidden transition. One of them corresponds to the situation when the total energy of emitted photons by two dipole-active radiators enter the two-photon resonance with the dipole-forbidden transition of third atom. Second effect corresponds to the scattering situation, when the difference of the excited energies of two dipole-active radiators is in the resonance with the dipole-forbidden transition of third atom. These effects are accompanied with the interferences between single- and two-quantum collective transitions of three inverted radiators from the ensemble. The three particle collective decay rate is defined in the description of the atomic correlation functions. © EDP Sciences, Società Italiana di Fisica, Springer-Verlag 2012.

We consider two independent symmetric Markov random flights Z 1(t) and Z 2(t) performed by the particles that simultaneously start from the origin of the Euclidean plane ℝ2 in random directions distributed uniformly on the unit circumference S 1 and move with constant finite velocities c 1>0, c 2>0, respectively. The new random directions are taking uniformly on S 1 at random time instants that form independent homogeneous Poisson flows of rates λ 1>0, λ 2>0. The probability distribution function Φ(r,t)= Pr{ρ(t)0, is derived. Asymptotics of Φ(r,t), as r→0, and a numerical example are also given. © 2013 Springer Science+Business Media New York.
