Analysis of RF-based Indoor Localization with Multiple Channels and Signal Strengths
(Springer, 2015)
In this paper, the influence and improvement of the localization accuracy achieved using a fingerprint database with information coming from different channels and radio signal strength levels is evaluated. This study uses ...
Revisiting the Gauss-Huard Algorithm for the Solution of Linear Systems on Graphics Accelerators
(Springer, 2016-04-02)
In 1979, P. Huard presented an efficient variant of the Gauss-Jordan elimination for the solution of linear systems. In particular, this alternative algorithm exhibits the same computational cost as the traditional LU-based ...
A Parallel Multi-threaded Solver for Symmetric Positive Definite Bordered-Band Linear Systems
(Springer, 2016-04)
We present a multi-threaded solver for symmetric positive definite linear systems where the coefficient matrix of the problem features a bordered-band non-zero pattern. The algorithms that implement this approach heavily ...
A Proposal to Extend the OpenMP Tasking Model for Heterogeneous Architectures
(Springer Berlin Heidelberg, 2009)
OpenMP has evolved recently towards expressing unstructured parallelism, targeting the parallelization of a broader range of applications in the current multicore era. Homogeneous multicore architectures from major vendors ...
A Rule-Based Multi-agent System for Local Traffic Management
(Springer Berlin Heidelberg, 2009)
Road Traffic presents a high dynamism which makes necessary the development of traffic management and control strategies to improve traffic flows and more important, road safety. So it is needed the use of intelligent ...
An Extension of the StarSs Programming Model for Platforms with Multiple GPUs
(Springer Berlin Heidelberg, 2009)
While general-purpose homogeneous multi-core architectures are becoming ubiquitous, there are clear indications that, for a number of important applications, a better performance/power ratio can be attained using specialized ...
Combining Multiple Classifiers with Dynamic Weighted Voting
(Springer Berlin Heidelberg, 2009)
When a multiple classifier system is employed, one of the most popular methods to accomplish the classifier fusion is the simple majority voting. However, when the performance of the ensemble members is not uniform, the ...
Dimensiones a considerar en el proceso de enseñanza-aprendizaje
(Octaedro, 2022-12)
La pandemia provocada por la covid-19 durante los años 2020 y 2021 obligó a
los centros de enseñanza universitaria de todo el mundo a realizar una adaptación urgente, en la que no fue posible realizar una reflexión profunda. ...
General Framework for Deriving Reproducible Krylov Subspace Algorithms: BiCGStab Case
(Springer, 2023)
Parallel implementations of Krylov subspace algorithms often help to accelerate the procedure to find the solution of a linear system. However, from the other side, such parallelization coupled with
asynchronous and ...
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 ...
