A Novel Bio-Inspired Approach for High-Performance Management in Service-Oriented Networks
2021
Service-continuity in distributed computing can be enhanced by designing self-organized systems, with a non-fixed structure, able to modify their structure and organization, as well as adaptively react to internal and external environment changes. In this paper, an architecture exploiting a bio-inspired management approach, i.e., the functioning of cell metabolism, for specialized computing environments in Service-Oriented Networks (SONs) is proposed. Similar to the processes acting in metabolic networks, the nodes communicate to each other by means of stimulation or suppression chains giving rise to emergent behaviors to defend against foreign invaders, attacks, and malfunctioning. The mai…
El aprendizaje servicio: una experiencia de participación y compromiso
2011
El Aprendizaje Servicio es una metodología innovadora que integra el servicio a la comunidad con el aprendizaje de contenidos, habilidades y valores. Desde el aprendizaje servicio se vincula la enseñanza a la vida misma, abriendo las puertas de la escuela a la comunidad. Se trata de aprender ayudando y de ayudar mientras se aprende. Este aprendizaje puesto en práctica tiene unos fines solidarios que a su vez mejoran la calidad de vida de la comunidad. Service Learning is an innovative methodology that integrates service to the community with the learning of content, skills and values. From service learning, teaching is linked to life itself, opening the doors of the school to the community.…
Aplicabilidad de un Score de TCAR para determinar la gravedad y el pronóstico en el momento del diagnóstico de la fibrosis pulmonar idiopática.
2016
Introducción: La TCAR es una exploración de primer orden en el diagnóstico y seguimiento de la fibrosis pulmonar idiopática (FPI), sin embargo no se utiliza para ponderar la gravedad. Bajo la hipótesis de que cuantificar la extensión de FPI en TCAR sería muy útil para establecer la gravedad al diagnóstico y monitorizar su evolución, nos propusimos evaluar la utilidad de un score semicuantitativo de FPI en TCAR en relación con parámetros funcionales habitualmente empleados para establecer la gravedad y monitorizar la evolución del proceso fibrótico. Pacientes y Método: Estudio prospectivo incluyendo 48 pacientes consecutivos diagnosticados de FPI. Mediante un score semicuantitativo se puntuó…
An Embedded Biometric Sensor for Ubiquitous Authentication
2013
Communication networks and distributed technologies move people towards the era of ubiquitous computing. An ubiquitous environment needs many authentication sensors for users recognition, in order to provide a secure infrastructure for both user access to resources and services and information management. Today the security requirements must ensure secure and trusted user information to protect sensitive data resource access and they could be used for user traceability inside the platform. Conventional authentication systems, based on username and password, are in crisis since they are not able to guarantee a suitable security level for several applications. Biometric authentication systems…

Movement Detection with Event-Based Cameras: Comparison with Frame-Based Cameras in Robot Object Tracking Using Powerlink Communication
2018
Event-based cameras are not common in industrial applications despite the fact that they can add multiple advantages for applications with moving objects. In comparison with frame-based cameras, the amount of generated data is very low while keeping the main information in the scene. For an industrial environment with interconnected systems, data reduction becomes very important to avoid network congestion and provide faster response time. However, the use of new sensors as event-based cameras is not common since they do not usually provide connectivity to industrial buses. This work develops a network node based on a Field Programmable Gate Array (FPGA), including data acquisition and trac…
NoC based virtualized FPGA as cloud Services
2016
International audience; Web-based applications are increasingly demanding many computationally intensive services. On the other hand, FPGA-based hardware accelerators(HwAcc) provide good performance in accelerating computationally intensive applications. In addition, some FPGAs support a dynamic partial reconfig-uration (DPR) techniques to virtualize and share the FPGA underlying hardware resources in time multiplexing during run-time to save resource and power consumption. Integrating FPGA in a cloud environment is an indispensable way to improve efficiency and provide acceleration services to demanding users. More importantly, in recent years it was proved that FPGA resources deployed in …
Design Space Exploration of Parallel Embedded Architectures for Native Clifford Algebra Operations
2012
In the past few decades, Geometric or Clifford algebra (CA) has received a growing attention in many research fields, such as robotics, machine vision and computer graphics, as a natural and intuitive way to model geometric objects and their transformations. At the same time, the high dimensionality of Clifford algebra and its computational complexity demand specialized hardware architectures for the direct support of Clifford data types and operators. This paper presents the design space exploration of parallel embedded architectures for native execution of four-dimensional (4D) and five-dimensional (5D) Clifford algebra operations. The design space exploration has been described along wit…
A Sliced Coprocessor for Native Clifford Algebra Operations
2007
Computer graphics applications require efficient tools to model geometric objects. The traditional approach based on compute-intensive matrix calculations is error-prone due to a lack of integration between geometric reasoning and matrix-based algorithms. Clifford algebra offers a solution to these issues since it permits specification of geometry at a coordinate-free level. The best way to exploit the symbolic computing power of geometric (Clifford) algebra is supporting its data types and operators directly in hardware. This paper outlines the architecture of S-CliffoSor (Sliced Clifford coprocessor), a parallelizable embedded coprocessor that executes native Clifford algebra operations. …
