A Multilevel Road Alignment Model for Spatial-Query-by-Sketch
(MDPI, 2020-11-01)
A sketch map represents an individual’s perception of a specific location. However, the information in sketch maps is often distorted and incomplete. Nevertheless, the main roads of a given location often exhibit considerable ...
Fast Algorithms for the Computation of the Minimum
Distance of a Random Linear Code
(Association for Computing Machinery (ACM), 2019-06)
The minimum distance of an error-correcting code is an important concept in information theory. Hence, computing the minimum distance of a code with a minimum computational cost is crucial to many problems in this area. ...
Hybrid static–dynamic selection of implementation alternatives in heterogeneous environments
(Springer, 2019-09)
With the emergence of heterogeneous architectures, developing parallel software has become an increasingly complex task. The ability of using multiple devices in a single application, such as CPUs, accelerators, or ...
Progressive image compression and transmission with region of interest in underwater robotics
(IEEE, 2017-06)
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 ...
Energy Balance between Voltage-Frequency Scaling and Resilience for Linear Algebra Routines on Low-Power Multicore Architectures
(Elsevier, 2018)
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 ...
Wireless HROV control with compressed visual feedback over an acoustic link
(IEEE, 2017-06)
This paper presents the current state of the devel-
opment of a Wireless HROV (Hybrid Remotely Operated Vehicle
HROV), providing feedback of both, camera and telemetry data
to the operator, over an ...
Increasing underwater manipulation autonomy using segmentation and visual tracking
(IEEE, 2017-06)
The present research in underwater robotics aims to increase the autonomy of manipulation operations in fields such as archaeology or biology, that cannot afford costly underwater interventions using traditional Remote ...
On the adequacy of lightweight thread approaches for high-level parallel programming models
(Elsevier, 2018-07)
High-level parallel programming models (PMs) are becoming crucial in order to extract the computational power of current on-node multi-threaded parallelism. The most popular PMs, such as OpenMP or OmpSs, are directive-based: ...
Static scheduling of the LU factorization with look-ahead on asymmetric multicore processors
(Elsevier, 2018)
We analyze the benefits of look-ahead in the parallel execution of the LU factorization with partial pivoting (LUpp) in two distinct “asymmetric” multicore scenarios. The first one corresponds to an actual hardware-asymmetric ...
A general scheme for finding the static rate–distortion optimized ordering for the bits of the coefficients of all subbands of an N-level dyadic biorthogonal DWT
(Elsevier, 2018)
The expected distortion decrease per bit attained by conveying the significance and refinement information of transform coefficients is derived taking into consideration their Probability Distribution Function (PDF) and ...
