3D Point Cloud Analysis via Transformer-Based Graph Learning for Multiple Sclerosis Screening in OCT Images
(Elsevier, 2024)[Abstract]: Multiple Sclerosis (MS), the leading cause of non-traumatic neurological impairment in young adults, manifests morphological changes in the retina observable in Optical Coherence Tomography (OCT) images. These ... -
3D Point Cloud Semantic Segmentation Through Functional Data Analysis
(Springer, 2023)[Abstract]: Here, we propose a method for the semantic segmentation of 3D point clouds based on functional data analysis. For each point of a training set, a number of handcrafted features representing the local geometry ... -
3D Retinal Vessel Tree Segmentation and Reconstruction with OCT Images
(Springer, 2016-07-01)[Absctract]: Detection and analysis of the arterio-venular tree of the retina is a relevant issue, providing useful information in procedures such as the diagnosis of different pathologies. Classical approaches for vessel ... -
3DGraCT: A Grammar-Based Compressed Representation of 3D Trajectories
(Springer, 2018)[Abstract]: Much research has been published about trajectory management on the ground or at the sea, but compression or indexing of flight trajectories have usually been less explored. However, air traffic management is ... -
60-GHz Millimeter-Wave Propagation Inside Bus: Measurement, Modeling, Simulation, and Performance Analysis
(Institute of Electrical and Electronics Engineers, 2019)[Abstract] Millimeter-wave (mmWave) transmission over the unlicensed 60-GHz spectrum is a potential solution to realize high-speed internet access, even inside mass transit vehicles. The solution involves communication ... -
A 2D algorithm with asymmetric workload for the UPC conjugate gradient method
(Springer New York LLC, 2014)[Abstract] This paper examines four different strategies, each one with its own data distribution, for implementing the parallel conjugate gradient (CG) method and how they impact communication and overall performance. ... -
A Bi-Objective Scheduling Problem in a Home Care Business
(MDPI, 2021)[Abstract] In this work we study a routing and scheduling problem for a home care business. The problem is composed of two conflicting objectives, therefore we study it as a bi-objective one. We obtain the Pareto frontier ... -
A Blended Artificial Intelligence Approach for Spectral Classification of Stars in Massive Astronomical Surveys
(MDPI AG, 2020-05-01)[Abstract] This paper analyzes and compares the sensitivity and suitability of several artificial intelligence techniques applied to the Morgan–Keenan (MK) system for the classification of stars. The MK system is based ... -
A Bluetooth 5 Opportunistic Edge Computing System for Vehicular Scenarios
(MDPI, 2022-11-01)[Abstract]: The limitations of many IoT devices in terms of storage, computing power and energy consumption require them to be connected to other devices when performing computationally intensive tasks, as happens with IoT ... -
A cardiotoxicity dataset for breast cancer patients
(Nature Research, 2023)[Abstract] This dataset is a result of the collaboration between the University of A Coruña and the University Hospital of A Coruña. It contains information about 531 women diagnosed with HER2+ breast cancer, treated with ... -
A centralized matching scheme to solve the role-partner allocation problem in collaborative networks
(Elsevier, 2022-07)[Abstract]: In the current constantly changing business and economic environment, partners (i.e., individuals and/or enterprises) create Collaborative Networks to join efforts and undertake new projects together, thus ... -
A classification and review of tools for developing and interacting with machine learning systems
(Association for Computing Machinery, 2022)[Abstract] In this paper we aim to bring some order to the myriad of tools that have emerged in the field of Artificial Intelligence (AI), focusing on the field of Machine Learning (ML). For this purpose, we suggest a ... -
A cloud-based enhanced differential evolution algorithm for parameter estimation problems in computational systems biology
(Springer New York LLC, 2017)[Abstract] Metaheuristics are gaining increasing recognition in many research areas, computational systems biology among them. Recent advances in metaheuristics can be helpful in locating the vicinity of the global solution ... -
A Collaborative Augmented Reality Application for Training and Assistance during Shipbuilding Assembly Processes
(MDPI AG, 2020-08-18)[Abstract] This paper presents the development of a novel Microsoft HoloLens collaborative application that allows shipyard operators to interact with a virtual clutch during its assembly in a real Turbine workshop. Such ... -
A common solution for tokenization and part-of-speech tagging: one-pass Viterbi algorithm vs. Iterative approaches
(Springer-Verlag, 2002)Current taggers assume that input texts are already tokenized, i.e. correctly segmented in \emph{tokens} or high level information units that identify each individual component of the texts. This working hypothesis is ... -
A Compact Representation of Indoor Trajectories
