Aggregated 2D range queries on clustered points
(Elsevier Ltd, 2016-09)[Abstract] Efficient processing of aggregated range queries on two-dimensional grids is a common requirement in information retrieval and data mining systems, for example in Geographic Information Systems and OLAP cubes. ... -
Parallel construction of wavelet trees on multicore architectures
(Springer U K, 2016-10-05)[Abstract] The wavelet tree has become a very useful data structure to efficiently represent and query large volumes of data in many different domains, from bioinformatics to geographic information systems. One problem ... -
Grammar compressed sequences with rank/select support
(Elsevier BV, 2016-10-14)[Abstract] Sequence representations supporting not only direct access to their symbols, but also rank/select operations, are a fundamental building block in many compressed data structures. Several recent applications need ... -
A succinct data structure for self-indexing ternary relations
(Elsevier BV, 2016-10-27)[Abstract] The representation of binary relations has been intensively studied and many different theoretical and practical representations have been proposed to answer the usual queries in multiple domains. However, ternary ... -
Universal indexes for highly repetitive document collections
(Elsevier Ltd, 2016-11)[Abstract] Indexing highly repetitive collections has become a relevant problem with the emergence of large repositories of versioned documents, among other applications. These collections may reach huge sizes, but are ... -
Scalable processing and autocovariance computation of big functional data
(John Wiley & Sons, 2018)[Abstract]: This paper presents 2 main contributions. The first is a compact representation of huge sets of functional data or trajectories of continuous-time stochastic processes, which allows keeping the data always ... -
GraCT: A Grammar-based Compressed Index for Trajectory Data
(Elsevier Ltd, 2019)[Abstract]: We introduce a compressed data structure for the storage of free trajectories of moving objects that efficiently supports various spatio-temporal queries. Our structure, dubbed GraCT, stores the absolute positions ... -
Optimization in Sanger sequencing
(Elsevier, 2019-09)[Abstract]: The main objective of this paper is to solve the optimization problem that is associated with the classification of DNA samples in PCR plates for Sanger sequencing. To achieve this goal, we design an integer ... -
Energy Consumption in Compact Integer Vectors: A Study Case
(Institute of Electrical and Electronics Engineers, 2019-10-25)[Abstract] In the field of algorithms and data structures analysis and design, most of the researchers focus only on the space/time trade-off, and little attention has been paid to energy consumption. Moreover, most of the ... -
Extending general compact querieable representations to GIS applications
(Elsevier, 2020-01)[Abstract]: The raster model is commonly used for the representation of images in many domains, and is especially useful in Geographic Information Systems (GIS) to store information about continuous variables of the space ... -
Efficient Processing of Raster and Vector Data
(Public Library of Science, 2020-01-10)[Abstract] In this work, we propose a framework to store and manage spatial data, which includes new efficient algorithms to perform operations accepting as input a raster dataset and a vector dataset. More concretely, we ... -
Compressed Data Structures for Binary Relations in Practice
(Institute of Electrical and Electronics Engineers, 2020-01-31)[Abstract] Binary relations are commonly used in Computer Science for modeling data. In addition to classical representations using matrices or lists, some compressed data structures have recently been proposed to represent ... -
An Action Research for Improving the Sustainability Assessment Framework Instruments
(MDPI AG, 2020-02-24)[Abstract] In the last years, software engineering researchers have defined sustainability as a quality requirement of software, but not enough effort has been devoted to develop new methods/techniques to support the ... -
A Public Domain Dataset for Real-Life Human Activity Recognition Using Smartphone Sensors
(MDPI AG, 2020-04-13)[Abstract] In recent years, human activity recognition has become a hot topic inside the scientific community. The reason to be under the spotlight is its direct application in multiple domains, like healthcare or fitness. ... -
An Architecture for Software Engineering Gamification
(Qinghua Daxue Xuebao Bianjibu,Tsinghua University, Editorial Board, 2020-05-07)[Abstract] Gamification has been applied in software engineering to improve quality and results by increasing people's motivation and engagement. A systematic mapping has identified research gaps in the field, one of them ... -
Automatic group-wise whole-brain short association fiber bundle labeling based on clustering and cortical surface information
(BioMed Central Ltd., 2020-06-03)[Abstract] Background Diffusion MRI is the preferred non-invasive in vivo modality for the study of brain white matter connections. Tractography datasets contain 3D streamlines that can be analyzed to study the main ... -
From Coarse to Fine-Grained Parcellation of the Cortical Surface Using a Fiber-Bundle Atlas
(Frontiers Research Foundation, 2020-09-10)[Abstract] In this article, we present a hybrid method to create fine-grained parcellations of the cortical surface, from a coarse-grained parcellation according to an anatomical atlas, based on cortico-cortical connectivity. ... -
Accessible Routes Integrating Data from Multiple Sources
(MDPI AG, 2020-12-26)[Abstract] Providing citizens with the ability to move around in an accessible way is a requirement for all cities today. However, modeling city infrastructures so that accessible routes can be computed is a challenge ... -
Boosting Perturbation-Based Iterative Algorithms to Compute the Median String
(IEEE, 2021)[Abstract] The most competitive heuristics for calculating the median string are those that use perturbation-based iterative algorithms. Given the complexity of this problem, which under many formulations is NP-hard, the ... -
Multilevel Modeling of Geographic Information Systems Based on International Standards
(SpringerLink, 2021)[Abstract] Even though different applications based on Geographic Information Systems (GIS) provide different features and functions, they all share a set of common concepts (e.g., spatial data types, operations, services), ...
