This work describes the implementation of a bioinspired visual processing system on configurable logic, designed for the enhancement of relevant information on a real scene, for its use on a complete system to assist the visually-impaired. For this purpose, a sensorial transduction module has been developed, which transforms visual information into sound patterns with 3D spatial localization. The requirements for this application, as portability, constrained power consumption, real-time performance, and customization to fit the specific features of the patient's affection, lead us to consider programmable logic as the best option for the design and development of the whole system, specifically FPGAs. A prototype of the system, including two video inputs with three spatial filters, two weighed sums, a disparity computation module, and the 3D sound generator, has been implemented on a Virtex-II XC2V6000, and performs at a maximum rate of 60 frames per second. © 2008 IEEE.

Traditionally, engineering studies have focused on preparing students technically and given little importance to social or ethical aspects, nor the ability to work in multi-disciplinary teams. Currently though, these skills are an added value and have been included in most prestigious centre's curricula. As a result, they have become a subject of study for the education community and the focus of numerous papers. Correspondingly, the Barcelona School of Informatics has developed a hardly explored initiative in order to inculcate these values and help students acquire these skills. This initiative gets them involved in what we call solidarity projects, where both students and professors get administrative and subsidized support to create cooperative work that will provide a solution to specific problems on developing countries and poor local areas. These projects may be introduced in some courses and during Bachelor and Master Thesis and have contributed towards the professional skills development of both students and professors involved. © 2008 IEEE.

Formal engineering with fuzzy logic

Formal engineering constitutes a very important issue in software engineering projects in real life. The developing of software does not always reach the desired level of reliability and performance even the life cycle of the project used to be controlled by methodologies and specific tools as Formal Languages and Formal Methods. Despite the efforts the question is that even in the best cases, the final product has a lot of errors and in some cases these errors produce catastrophic disasters (ARIANE 5, for example). This paper shows a new proposal to formalize the life cycle according to the worker at each stage and the importance of using not only the classical logics (propositional and first order), but also fuzzy logic in order to formalize the certain and uncertain information involved in natural language. © 2011 Springer-Verlag Berlin Heidelberg.

The use of Java for parallel programming on clusters according to the message-passing paradigm is an attractive choice. In this case, the overall application performance will largely dep.nd on the performance of the underlying Java message-passing library. This paper evaluates, models and compares the performance of MPI-like point-to-point and collective communication primitives from selected Java message-passing implementations on clusters with different interconnection networks. We have developed our own micro-benchmark suite to characterize the message-passing communication overhead and thus derive analytical latency models. © 2003 IEEE.

Classification techniques based on Artificial Intelligence are computational tools that have been applied to detection of intrusions (IDS) with encouraging results. They are able to solve problems related to information security in an efficient way. The intrusion detection implies the use of huge amount of information. For this reason heuristic methodologies have been proposed. In this paper, decision trees, Naive Bayes, and supervised classifying systems UCS, are combined to improve the performance of a classifier. In order to validate the system, a scenario based on real data of the NSL-KDD99 dataset is used. © 2014 IEEE.

Parallelization strategies for the VMEC program 4th

The magnetohydrodynamic equilibrium problem in magnetic confinement fusion devices is solved by using the Variational Moments Equilibrium Code (VMEC). The sequential version of the code is computationally very expensive and may take several days of CPU time. In this work we present two parallelization techniques for the code. First, an automatic tool has been used as a guidance for the parallelization of the critical parts of the code, and some deficiencies of its automatic parallelization techniques have been determined. In a second approach, these shortcomings are overcome to develop manual techniques which offer better results and can be used in future automatic parallelizers. © Springer-Verlag Berlin Heidelberg 1998.

In this paper it is analyzed the topology of *** Wireless Community Network (WCN). WCN have emerged in recent years organized and dep.oyed by the cooperation of its own customers. WCN keep parallelisms with the construction of the Internet, and seems logical to look for common characteristics among them. More specifically, it is investigated whether there are topology patterns of ***, and to what extend they share the power-law properties that have been found to obey many topology parameters of the Internet. The paper also proposes a topology generator algorithm that it is able to reproduce specific graph properties that have been obtained for ***. © 2012 IEEE.

Opportunistic Routing (OR) has been proposed to improve the efficiency of unicast protocols in wireless networks. In contrast to traditional routing, instead of preselecting a single specific node to be the next-hop forwarder, an ordered set of nodes (referred to as candidates) is selected as the next-hop potential forwarders. In this paper, we propose a new multicast routing protocol based on OR for wireless mesh networks, named Multicast OR Protocol (MORP). We compare our proposal with the well known ODMRP Multicast protocol. Our results show that Multicast-OR outperforms ODMRP, reducing the number of transmissions and increasing the packet delivery ratio. © 2011 IFIP International Federation for Information Processing.

This paper describes an ant-based clustering algorithms and suggests its application as a swarm art conceptual tool. The algorithm, called KANTS, consists on a set of equations that model the local behavior of simple units (ants) that represent data samples. When moving on a heterogeneous 2-dimensional lattice of vectors, global behavior emerges from the local interaction between the ants, which self-organize into clusters. In this paper, KANTS is used outside a purely scientific framework. The algorithm is applied to two different types of data (sleep Electroencephalogram signals and colored photographs) for generating 2-dimensional abstract representations of those sets of data. We call the images pherogenic drawings, since they are a visual representation of the algorithm's pheromone maps. The method is contextualized within the swarm art field as well as within the authors' previous works on swarm art. © 2012 IEEE.

Efficient OpenCL-based concurrent tasks offloading on accelerators

引用

Procedia computer Science 2017年 108卷 2353-2357页

作者： A.J. Lázaro-Muñoz J.M. González-Linares J. Gómez-Luna N. Guil Dep. of Computer Architecture University of Malaga Spain Dep. of Computer Architecture and Electronics University of Córdoba Spain

Current heterogeneous platforms with CPUs and accelerators have the ability to launch several indep.ndent tasks simultaneously, in order to exploit concurrency among them. These tasks typically consist of data transfer commands and kernel computation commands. In this paper we develop a runtime approach to optimize the concurrency between data transfers and kernel computation commands in a multithreaded scenario where each CPU thread offloads tasks to the accelerator. It dep.oys a heuristic based on a temporal execution model for concurrent tasks. It is able to establish a near-optimal task execution order that significantly reduces the total execution time, including data transfers. Our approach has been evaluated employing five different benchmarks composed of dominant kernel and dominant transfer real tasks. In these experiments our heuristic achieves speedups up to 1.5x in AMD R9 and NVIDIA K20c accelerators and 1.3x in an Intel Xeon Phi (KNC) device.
