The Socientize project will coordinate all the agents involved in the citizen science setting the basis of this new open science paradigm promoting the usage of the infrastructures composed by dedicated and external resources which are based on scientists and amateur people. It will set a network where infrastructure providers and scientific researchers will join with the society recruiting volunteers that perform science at home. With the citizen science term we mean both a) the participation of people in the scientific process, i.e. By collecting and analysing scientific data or by contributing with their own resources to form the research infrastructure, and b) the development of socio-artistic activities and dissemination material of scientific results for them.\n\nPeople will contribute with their own knowledge and resources participating in an active way. As we propose to open e-infrastructure to the people, even considering the knowledge and the time of the citizen scientists as part of the resources that constitute the infrastructure, he present here an innovative concept: the human-based e-infrastructure (he-infrastructure). These infrastructure allow researchers to deploy new studies, dealing with large-scale data. For instance, the research over the socio-technological networks is allowing to emerge a new collective intelligence able to deploy innovative scientific tasks.\n\nSOCIENTIZE will deploy a set of applications enabling volunteers as scientists and showing the capabilities of open resources. But the project will be focused in open workshops and conferences where the partnership will set the basis of the interaction with all the stakeholders. As a result of the discussions held in the SOCIENTIZE fora, we will present a white-book with the strategy for the citizen science enhancement, compiling best cases experiences and policy recommendations for he-infrastructure providers, scientific end-users, artists and the society in general.

The FP7 EDGeS project has successfully set up a production-level distributed computing infrastructure (DCI) consisting of more than 100.000 PCs from several volunteer and low-cost Desktop Grids, which have been connected to existing Service Grids (including EGEE, SEE-GRID, etc. with about 150.000 processors) based on the new 3G Bridge technology and application development methodology.\n\nThe main aim of the DEGISCO project is the further extension of the European DCI infrastructure that is already interconnected by EDGeS to International Cooperation Partner Countries (ICPC) in strong collaboration with on the one hand local partners in ICPC countries and on the other hand European e-Infrastructure experts (including 3G Bridge know-how) and thus, reinforce the global relevance and impact of European distributed infrastructures.\n\nThe project will support the creation of new Desktop Grids in ICPC countries and the connection of these Grids to European DCIs and existing Service Grids in ICPC countries by employing 3G Bridge technology. Moreover, building on the solid expertise of the DEGISCO partners, the project will provide recommendations on best practices and define joint roadmaps for ICPC countries and Europe.\n\nThe application support activities of DEGISCO support the use of the already two dozen ported applications on new connected DCIs in ICPC countries and support new applications.\n\nThe dissemination and training activities will promote via various channels such interoperation between Desktop Grid and Service Grid infrastructures on a global scale, which leads to more awareness under the general public of computational science and distributed computing co-funded by the EC. As a result more citizens, students, and companies are expected to donate resources to scientific purposes.\n\n\nAs part of these activities an International Desktop Grid Federation will be operated allowing for effective exchange of information through participation.

We study the muon anomalous magnetic moment in an electroweak model based on the gauge symmetry SU(4)L ⊗ U(1)N, which has right-handed neutrinos in its spectrum, and no flavor changing neutral currents at tree level. We discuss relevant collider and electroweak constraints on the model, and derive the most stringent upper bounds on the scale of symmetry breaking based on the corrections to the muon magnetic moment. We conclude that a scale of symmetry breaking of around 2 TeV might explain the muon magnetic moment anomaly. In case the anomaly is otherwise resolved, using the current and projected sensitive of g-2 experiments, we rule out scales of symmetry breaking smaller than 3.5 TeV (5.5 TeV) at 1σ level. © 2015 World Scientific Publishing Company.

This paper deals with radial distribution network reconfiguration for loss and switching mitigation. Its main contribution is the presentation of a genetic algorithm (GA) with two network encodings, capable of representing only radial connected solutions without demanding a planar topology or any specific genetic operator. The code was named sequential because the evaluation of the ith gene depends on the information forthcoming from all the previous genes. In addition to a full description of proposed techniques with examples, the paper presents a survey of existing network codifications including their search space and chromosomes for a 33-bus example system. In order to validate the proposed algorithms, these and other two techniques in the state of the art are applied to reconfigure three sample systems which have been broadly published in the technical literature. Performance is assessed by using the results of implemented representations and the reconfiguration literature. © 2010 IEEE.

In this paper we consider the scattering of massless planar scalar waves by a noncommutative BTZ black hole. We compute the differential cross section via the partial wave approach, and we mainly show that the scattering of planar waves leads to a modified Aharonov-Bohm effect due to spacetime noncommutativity. © 2015.

In this paper, using a (2+1)-dimensional field theory approach, we study the Aharonov-Bohm (AB) scattering with Lorentz symmetry breaking. We obtain the modified scattering amplitude to the AB effect due to the small Lorentz violation correction in the breaking parameter and prove that up to one loop the model is free from ultraviolet divergences. © 2015 American Physical Society.

In this study wind resources evaluation and wind energy assessment of the São João do Cariri (SJC) in Paraiba (PB) state situated in Brazilian northeast were analyzed during the period 2006/2009. Wind speed (V, m/s), wind direction and air temperature (T, °C) at 25 m and 50 m were collected from SONDA (Sistema de Organizaão Nacional de Dados Ambientais) meteorological station (38°N 7°E). The average wind speed and temperature for 25 m and 50 m were found 4.74 m/s, 24.46 °C and 5.31 m/s 24.25 °C respectively. The wind speed predominate direction found were SSE (165°) from both 25 m and 50 m heights. The wind speed distribution curve was obtained using the Weibull probability density function through the WAsP program, the values of Weibull shape (K), scale (A, m/s) and Weibull fit wind speed and power wind density (P, W/m2) were found 2.54, 5.4 m/s, 4.76 m/s and 103 W/m 2 for 25 m wind height measurements and 2.59, 6.0 m/s, 5.36 m/s and 145 W/m2 for 50 m wind height measurements. The cost (/kWh) from electrical wind energy obtained by wind turbine generation, at 25 m height, was found 0.046 by using 300 kW power rated wind turbine, in the best scenario, with an associate Cf of 14.5%. © 2011 Elsevier Ltd.
