Accelerating Model Reduction of Large Linear Systems with Graphics Processors
(Springer Berlin Heidelberg, 2012)
Model order reduction of a dynamical linear time-invariant system appears in many applications from science and engineering. Numerically reliable SVD-based methods for this task require in general O(n3) floating-point ...
Parallelization of Multilevel ILU Preconditioners on Distributed-Memory Multiprocessors
(Springer Berlin Heidelberg, 2012)
In this paper we investigate the parallelization of the ILUPACK library for the solution of sparse linear systems on distributed-memory multiprocessors. The parallelization approach employs multilevel graph partitioning ...
A Pilot Study on Saccadic Adaptation Experiments with Robots
(Springer Berlin Heidelberg, 2012)
Despite the increasing mutual interest, robotics and cognitive sciences are still lacking common research grounds and comparison methodologies, for a more efficient use of modern technologies in aid of neuroscience research. ...
Integration of Static and Self-motion-Based Depth Cues for Efficient Reaching and Locomotor Actions
(Springer Berlin Heidelberg, 2012)
The common approach to estimate the distance of an object in computer vision and robotics is to use stereo vision. Stereopsis, however, provides good estimates only within near space and thus is more suitable for reaching ...
Leveraging Task-Parallelism in Energy-Efficient ILU Preconditioners
(Springer Berlin Heidelberg, 2012)
We analyze the energy-performance balance of a task-parallel computation of an ILU-based preconditioner for the solution of sparse linear systems on multi-core processors. In particular, we elaborate a theoretical model ...
Plastic Representation of the Reachable Space for a Humanoid Robot
(Springer Berlin Heidelberg, 2012)
Reaching a target object requires accurate estimation of the object spatial position and its further transformation into a suitable arm-motor command. In this paper, we propose a framework that provides a robot with a ...
Accelerating BST Methods for Model Reduction with Graphics Processors
(Springer Berlin Heidelberg, 2012)
Model order reduction of dynamical linear time-invariant system appears in many scientific and engineering applications. Numerically reliable SVD-based methods for this task require O(n3) floating-point arithmetic operations, ...
Investigación práctica en educación : investigación-acción
(TICAI, Sociedad de Educación, 2012)
This paper describes the methodology of action research, an educational research methodology in which professors investigate on their own teaching practices. In this work we also justify the need of using such methodology ...
