Nowadays increasing fuel prices and upcoming pollutant emission regulations are becoming a growing concern for the shipping industry worldwide. While fuel prices will keep rising in future years, the new International Convention for the Prevention of Pollution from Ships (MARPOL) and Sulphur Emissions Control Areas (SECA) regulations will forbid ships to use heavy fuel oils at certain situations. To fulfil with these regulations, the next step in the marine shipping business will comprise the use of cleaner fuels on board as well as developing new propulsion concept. In this work a new conceptual marine propulsion system is developed, based on the integration of diesel generators with fuel cells in a 2850 metric tonne of deadweight platform supply vessel. The efficiency of the two 250 kW methanol-fed Solid Oxide Fuel Cell (SOFC) system installed on board combined with the hydro dynamically optimized design of the hull of the ship will allow the ship to successfully operate at certain modes of operation while notably reduce the pollutant emissions to the atmosphere. Besides the cogeneration heat obtained from the fuel cell system will be used to answer different heating needs on board the vessel

A study on the manoeuvrability of a riverine support patrol vessel is made to derive a mathematical model and simulate maneuvers with this ship. The vessel is mainly characterized by both its wide-beam and the unconventional propulsion system, that is, a pump-jet type azimuthal propulsion. By processing experimental data and the ship characteristics with diverse formulae to find the proper hydrodynamic coefficients and propulsion forces, a system of three differential equations is completed and tuned to carry out simulations of the turning test. The simulation is able to accept variable speed, jet angle and water depth as input parameters and its output consists of time series of the state variables and a plot of the simulated path and heading of the ship during the maneuver. Thanks to the data of full-scale trials previously performed with the studied vessel, a process of validation was made, which shows a good fit between simulated and full-scale experimental results, especially on the turning diameter

Methodology and results of full scale maneuvering trials for Riverine Support Patrol Vessel “RSPV”, built by COTECMAR for the Colombian Navy are presented. !is ship is equipped with a “Pump – Jet” propulsion system and the hull corresponds to a wide-hull with a high Beam – Draft ratio (B/T=9.5). Tests were based on the results of simulation of turning diameters obtained from TRIBON M3© design software, applying techniques of Design of Experiments “DOE”, to rationalize the number of runs in di"erent conditions of water depth, ship speed, and rudder angle. Results validate the excellent performance of this class of ship and show that turning diameter and other maneuvering characteristics improve with decreasing water depth.

Providing experimental facilities for the Internet of Things (IoT) world is of paramount importance to materialise the Future Internet (FI) vision. The level of maturity achieved at the networking level in Sensor and Actuator networks (SAN) justifies the increasing demand on the research community to shift IoT testbed facilities from the network to the service and information management areas. In this paper we present an Experimental Platform fulfilling these needs by: integrating heterogeneous SAN infrastructures in a homogeneous way; providing mechanisms to handle information, and facilitating the development of experimental services. It has already been used to deploy applications in three different field trials: smart metering, smart places and environmental monitoring and it will be one of the components over which the SmartSantander project, that targets a large-scale IoT experimental facility, will rely on

Modern FPGAs with run-time reconfiguration allow the implementation of complex systems offering both the flexibility of software-based solutions combined with the performance of hardware. This combination of characteristics, together with the development of new specific methodologies, make feasible to reach new points of the system design space, and make embedded systems built on these platforms acquire more and more importance. However, the practical exploitation of this technique in fields that traditionally have relied on resource restricted embedded systems, is mainly limited by strict power consumption requirements, the cost and the high dependence of DPR techniques with the specific features of the device technology underneath. In this work, we tackle the previously reported problems, designing a reconfigurable platform based on the low-cost and low-power consuming Spartan-6 FPGA family. The full process to develop the platform will be detailed in the paper from scratch. In addition, the implementation of the reconfiguration mechanism, including two profiles, is reported. The first profile is a low-area and low-speed reconfiguration engine based mainly on software functions running on the embedded processor, while the other one is a hardware version of the same engine, implemented in the FPGA logic. This reconfiguration hardware block has been originally designed to the Virtex-5 family, and its porting process will be also described in this work, facing the interoperability problem among different families.

Acquired Brain Injury (ABI), either caused by vascular or traumatic nature, is one of the most important causes for neurological disabilities. People who suffer ABI see how their quality of life decreases, due to the affection of one or some of the cognitive functions (memory, attention, language or executive functions). The traditional cognitive rehabilitation protocols are too expensive, so every help carried out in this area is justified. PREVIRNEC is a new platform for cognitive tele-rehabilitation that allows the neuropsychologist to schedule rehabilitation sessions consisted of specifically designed tasks, plus offering an additional way of communication between neuropsychologists and patients. Besides, the platform offers a knowledge management module that allows the optimization of the cognitive rehabilitation to this kind of patients.

La idea inicial de este proyecto surge de la necesidad de desarrollar una herramienta software que ayudase a estudiantes de un curso de iniciación de álgebra lineal a adquirir los conceptos expuestos en el curso mediante la asistencia de cálculos y la representación visual de conceptos e ideas. Algunas de las características o funcionalidades que debería cumplir la herramienta serían: cálculo simbólico, representación simbólica, interfaz gráfico interactivo (point-and-click para realizar operaciones y cálculos, inserción de elementos gráficos mediante drag-and-drop desde una paleta de elementos, representación visual esquemática, representación gráfica 2D y 3D...), persistencia del modelo de datos, etc. Esta fase de un proyecto puede definirse como el – qué –. El siguiente paso o fase del proyecto trata del diseño del proyecto o el – cómo –. Cómo realizar el cálculo numérico, cómo representar símbolos matemáticos en pantalla, cómo crear una paleta de elementos. . . Seguramente existen bibliotecas o APIs de programación para realizar todas estas tareas, sin embargo, su utilización exige al programador tiempo de aprendizaje y el diseño de integración de las diferentes bibliotecas (compatibilidad de versiones, mecanismos de comunicación entre ellas, configuración, etc.). Lo primero puede resolverse fácilmente dedicando tiempo de estudio a la documentación, pero ya implica tiempo. Lo segundo implica además tener que tomar decisiones sobre cómo realizar la integración, no es trivial llegar a dibujar en pantalla, mediante una API de visualización gráfica, una matriz resultado de realizar ciertas operaciones mediante un API de cálculo de álgebra lineal. Existen varias bibliotecas de cálculo de álgebra lineal en las que apoyarse para realizar cálculos. Así pues, es fácil encontrar una biblioteca o API con funciones para realizar operaciones con matrices. Lo que no resulta tan sencillo es encontrar un API que permita definir al programador los mecanismos para representar la matriz en pantalla o para que el usuario introduzca los valores de la matriz. Es en estas últimas tareas en las que el programador se ve obligado a dedicar la mayor parte del tiempo de desarrollo. El resultado de este proyecto supone una gran simplificación de esta segunda fase, la parte del – cómo –, estableciendo una plataforma sobre la que futuros desarrollos puedan basarse para obtener resultados de alta calidad sin tener que preocuparse de las tareas ajenas a la lógica del programa.

To date, big data applications have focused on the store-and-process paradigm. In this paper we describe an initiative to deal with big data applications for continuous streams of events. In many emerging applications, the volume of data being streamed is so large that the traditional ‘store-then-process’ paradigm is either not suitable or too inefficient. Moreover, soft-real time requirements might severely limit the engineering solutions. Many scenarios fit this description. In network security for cloud data centres, for instance, very high volumes of IP packets and events from sensors at firewalls, network switches and routers and servers need to be analyzed and should detect attacks in minimal time, in order to limit the effect of the malicious activity over the IT infrastructure. Similarly, in the fraud department of a credit card company, payment requests should be processed online and need to be processed as quickly as possible in order to provide meaningful results in real-time. An ideal system would detect fraud during the authorization process that lasts hundreds of milliseconds and deny the payment authorization, minimizing the damage to the user and the credit card company.

One of the main challenges facing next generation Cloud platform services is the need to simultaneously achieve ease of programming, consistency, and high scalability. Big Data applications have so far focused on batch processing. The next step for Big Data is to move to the online world. This shift will raise the requirements for transactional guarantees. CumuloNimbo is a new EC-funded project led by Universidad Politécnica de Madrid (UPM) that addresses these issues via a highly scalable multi-tier transactional platform as a service (PaaS) that bridges the gap between OLTP and Big Data applications.

Personalized health (p-health) systems can contribute significantly to the sustainability of healthcare systems, though their feasibility is yet to be proven. One of the problems related to their development is the lack of well-established development tools for this domain. As the p-health paradigm is focused on patient self-management, big challenges arise around the design and implementation of patient systems. This paper presents a reference platform created for the development of these applications, and shows the advantages of its adoption in a complex project dealing with cardio-vascular diseases.

This paper presents a proposal for an advanced system of debate in an environment of digital democracy which overcomes the limitations of existing systems. We have been especially careful in applying security procedures in telematic systems, for they are to offer citizens the guarantees that society demands. New functional tools have been included to ensure user authentication and to permit anonymous participation where the system is unable to disclose or even to know the identity of system users. The platform prevents participation by non-entitled persons who do not belong to the authorized group from giving their opinion. Furthermore, this proposal allows for verifying the proper function of the system, free of tampering or fraud intended to alter the conclusions or outcomes of participation. All these tools guarantee important aspects of both a social and technical nature, most importantly: freedom of expression, equality and auditability.
