Assisting therapists in assessing small animal phobias by computer analysis of video-recorded sessions
(Springer, 2017)
Behavioural Avoidance Tests (BATs) are commonly used for assessing phobias. While easy to deploy, these tests have some practical difficulties. For instance, therapists have to make distance estimations that are hard to ...
GPU-based Dynamic Wave Field Synthesis using Fractional Delay Filters and Room Compensation
(IEEE, 2017-02)
Wave Field Synthesis (WFS) is a multichannel audio reproduction method, of a considerable computational
cost that renders an accurate spatial sound field using a large number of loudspeakers to emulate
virtual sound ...
Underwater radio frequency image sensor using progressive image compression and region of interest
(Springer-Verlag, 2017-08)
The increasing demand for underwater robotic intervention systems around the world in several application domains requires more versatile and inexpensive systems. By using a wireless communication system, supervised ...
On the benefits of the remote GPU virtualization mechanism: The rCUDA case
(Wiley, 2017-07-10)
Graphics processing units (GPUs) are being adopted in many computing facilities given their extraordinary computing power, which makes it possible to accelerate many general purpose applications from different domains. ...
Extending the Gauss-Huard method for the solution of Lyapunov matrix equations and matrix inversion
(Wiley, 2017-05-10)
The solution of linear systems is a recurrent operation in scientific and engineering applications, traditionally addressed via the LU factorization. The Gauss-Huard (GH) algorithm has been introduced as an efficient ...
Argobots: A Lightweight Low-Level Threading and Tasking Framework
(IEEE, 2017-10)
In the past few decades, a number of user-level threading and tasking models have been proposed in the literature to address the shortcomings of OS-level threads, primarily with respect to cost and flexibility. Current ...
Revisiting conventional task schedulers to exploit asymmetry in multi-core architectures for dense linear algebra operations
(Elsevier, 2017)
Dealing with asymmetry in the architecture opens a plethora of questions related with
the performance- and energy-efficient scheduling of task-parallel applications. While there
exist early attempts to tackle this problem, ...
Energy Balance between Voltage-Frequency Scaling and Resilience for Linear Algebra Routines on Low-Power Multicore Architectures
(Elsevier, 2017)
Near Threshold Voltage (NTV) computing has been recently proposed as a technique to save energy, at the cost of incurring higher error rates including, among others, Silent Data Corruption (SDC). In this paper, we evaluate ...
An adaptive offline implementation selector for heterogeneous parallel platforms
(Universidad de Salamanca, 2017-03)
Heterogeneous parallel platforms, comprising multiple processing units and architectures, have become a cornerstone in improving the overall performance and energy efficiency of scientific and engineering applications. ...
Householder QR Factorization With Randomization for Column Pivoting (HQRRP)
(Society for Industrial and Applied Mathematics, 2017)
A fundamental problem when adding column pivoting to the Householder QR fac-
torization is that only about half of the computation can be cast in terms of high performing matrix-
matrix multiplications, which greatly ...
