EOSC ,Design ,Earth Observation ,C-SCALE ,Federation ,Compute ,Copernicus - Abstract
The C-SCALE Compute Federation brings together European commercial (e.g. Copernicus DIAS) and public (from e-infrastructure) computing providers to deliver a federated infrastructure to support Copernicus and Earth Observation (EO) use cases that deal with data- and compute-intensive workloads. The federation makes computing e-Infrastructure, potentially consisting of multiple services provided collaboratively by several service providers, accessible through homogeneous interfaces using a common AAI framework. Hence, C-SCALE facilitates the deployment of research applications that make use of EO and Copernicus datasets, e.g. Sentinel-series satellite data, that are distributed across multiple providers. This document describes the overall architecture of the C-SCALE Compute Federation, that provides users with the baseline computing resources to perform Earth Observation related analytics on a distributed e-Infrastructure.

Virtual Research Environments ,Agro-Climatic ,Food Safety ,Food Security ,agriculture - Abstract
The main purpose of this deliverable is to present the sustainability approach of the AGINFRA+ project results. Its target audience comprises representatives of external interested communities as well as the European Commission (i.e. main funder of the AGINFRA+ project). More precisely, the document examines three action lines, each dedicated to sustain a main output of the AGINFRA+ project, namely: Consultancy service to deploy and configure custom VREs for agri-food research communities: corresponds to Virtual Research Environments (VREs) that can be developed and deployed as a service to various agri-food communities based on (a) the D4Science infrastructure (https://www.d4science.org/) and (b) the customization of generic or domain specific services offered by various partners, which have been tested and validated with agri-food researchers during the project lifetime. Data Journals: corresponds to the two data journals that we have been set-up based on the ARPHA publishing platform (http://arphahub.com/), namely the Food Modelling Journal (https://fmj.pensoft.net/) and the Viticulture Data Journal (https://vdj.pensoft.net/) Thematic VREs: corresponds to the four VREs that have been set-up during the project lifetime for supporting the three user communities of the project, namely (a) one VRE for Agro-Climatic and Economic Modelling community, (b) two VREs for the Food Safety Risk Assessment Community and (c) one VRE for Food Security Community Additionally, the report examines the management of AGINFRA+ after the end of the project funding. More specifically, although in the project DoA it has been proposed the establishment of a legal entity form (through a not-for-profit association) for the further operation and evolution of AGINFRA+ as a joint venture of involved stakeholders, it seems that this solution will not be operational considering the blend of the consortium partners involved. Thus, it has been considered among the partners that it will be better cost and operational wise to manage AGINFRA+ through a Memorandum of Agreement for a specified period (e.g. until December 2020) that will ensure that AGINFRA+ will be active in the EU infrastructures map and available to users with the support needed. Finally, the report concludes with the presentation of the foreseen next steps and the decisions that need to be further discussed among the consortium partners during the last year of the project towards finalizing the proposed sustainability plan of the project results.

VIRTUAL reality ,VIRTUAL communities ,COMMUNITIES ,ACQUISITION of data ,FOOD security - Abstract
The enhancements in IT solutions and the open science movement are injecting changes in the practices dealing with data collection, collation, processing, analytics, and publishing in all the domains, including agri‐food. However, in implementing these changes one of the major issues faced by the agri‐food researchers is the fragmentation of the "assets" to be exploited when performing research tasks, for example, data of interest are heterogeneous and scattered across several repositories, the tools modelers rely on are diverse and often make use of limited computing capacity, the publishing practices are various and rarely aim at making available the "whole story" including datasets, processes, and results. This paper presents the AGINFRA PLUS endeavor to overcome these limitations by providing researchers in three designated communities with Virtual Research Environments facilitating the use of the "assets" of interest and promote collaboration.

MPI-START ,Software_PROGRAMMINGTECHNIQUES ,EMI ,MPI-UTILS - Abstract
mpi-start is a set of scripts to close the gap between the workload management system of a Grid insfrastructure and the configuration of the nodes on which MPI applications are run. The package is used to help the user to start MPI applications on heterogeneous Grid sites. mpi-start provides an abstraction layer that offers a unique interface to start parallel jobs with different execution environments implementations. It supports several different MPI implementations under different batch systems. mpi-start was originally developed in the frame of the int.eu.grid project for the execution of MPI applications with the CrossBroker metascheduler and then extended its use as the official way of starting MPI jobs within EGEE. Currently, it is part of the EMI project. There is a trac page at http://devel.ifca.es/mpi-start with information about the development of mpi-start., This work is co-funded by the EC EMI project under the FP7 Collaborative Projects Grant Agreement Nr. INFSO-RI-261611.

Java (Lenguaje de programación) ,Multimedia ,Videoconferencia ,Desarrollo de software ,Redes de comunicación - Abstract
El siguiente TFG se basa en el desarrollo de un programa en Java que modifique paquetes SIP (Session Initiation Protocol) que contengan solicitudes INVITE con el fin de mejorar las comunicaciones multimedia, sobre todo las videoconferencias. Esta modificación consistirá en seleccionar los codecs adecuados en función del ancho de banda disponible en la red de acceso del usuario. El trabajo está dirigido para su instalación en una Whitebox de Samknows, enmarcándose dentro del proyecto que la empresa está desarrollando junto con la Comisión Europea. La solución propuesta se desarrollará en tres partes: 1. Recepción del paquete: se desviará el paquete hacia un puerto determinado, donde nuestro programa tendrá una pila escuchando las solicitudes que lleguen y su tipo. 2. Obtención de la información multimedia: obtendremos la información multimedia de la carga SDP (Session Description Protocol) y la compararemos con la que nos daría una buena calidad en función del ancho de banda disponible en ese momento, quedándonos con los codecs comunes a ambos. 3. Modificación del mensaje: una vez sepamos los codecs comunes, modificaremos la carga SDP y posteriormente el mensaje, para enviarlo modificado al servidor. Esta modificación se realiza de manera transparente al usuario y en tiempo real, con el fin de obtener un mejor rendimiento y experiencia de usuario en las comunicaciones multimedia, sin que esto suponga una penalización en términos de instalación del software, utilización de éste y tiempo de espera para iniciar las comunicaciones. The next Bachelor Thesis is based on the development of a Java program that modifies SIP (Session Initiation Protocol) packets which contain INVITE request with the goal of improving multimedia communications, mainly videoconferences. This modification will consist on selecting the right codecs depending on the available bandwidth at the user access network. The job is focused for its installation in a Smaknows Whitebox, framing itself inside the project the company is developing with the European Commission (EC). The proposed solution will be developed in three steps: 1. Packet reception: the packet will be redirected towards a well-known port, where our program will have a stack which is listening to the arrived requests and its type. 2. Getting the multimedia information: we will get the multimedia information from the SDP (Session Description Protocol) load and we will compare it with the one that would give us good quality according to the available bandwidth at this moment, choosing the common codecs. 3. Message modification: when we know de common codecs, we will modify the SDP load and the message with it, and we will send de modified packet to the server. This modification is done transparently for the user and in real-time, with the purpose of getting a better performance and user experience in the multimedia communications, but don’t supposing a penalization in terms of software installation, use and wait time to start the communications Ingeniería de Sistemas Audiovisuales

P-waves (Seismology) ,ACOUSTIC impedance ,NONDESTRUCTIVE testing - Abstract
In the case of a two-layer system, the impact-echo test has classically assumed that two frequency peaks are expected in the spectrum. In this paper, the spectrum of the impact-echo test is studied from a guided-wave approach both for the single-layer and for the two-layer cases. The results show that the classical impact-echo interpretation cannot predict, in general, the position of the peaks and that the classical results based on the impedance contrast between layers are not valid. As an alternative, a guided-wave approach based on the dispersion curves of the system is presented. Reasons why the impact-echo classical interpretation seems to work successfully in some cases are given. It is found that only in the particular cases where the times of flight of the P waves inside each layer, separately, are very similar, the classical predictions are valid for the main frequency. Finally, it is shown that the frequency peak values always correspond with zero group velocity frequencies or with cutoff frequencies in the dispersion curves. Results are tested with real field work. [ABSTRACT FROM AUTHOR]

- Abstract
Grid systems offer high computing capabilities that are used in many scientific research fields and thus many applications are submitted to these powerful systems. Parallel applications and applications consisting of inter-dependent jobs may especially be characterized by a complex workflow. Therefore, Grid systems should be capable of executing and controlling workflow computations. This document sets out our approach to workflow management in a Grid environment. It introduces common steps on how to map an application workflow to the DAG structure, and how to carry out its execution and control. We present the Workflow Management Service (WFMS) implemented and integrated as a part of the CrossGrid project. The purpose of this service is to schedule workflow computations according to user-defined requirements, also providing a set of mechanisms to deal with failures in Grid. [ABSTRACT FROM AUTHOR]
