2D SLAM Algorithms Characterization, Calibration, and Comparison Considering Pose Error, Map Accuracy, CPU Usage, and Memory Usage
(2022)The present work proposes a method to characterize, calibrate, and compare, any 2D SLAM algorithm, providing strong statistical evidence, based on descriptive and inferential statistics to bring confidence levels about ... -
A Comparative Study on Denoising Algorithms for Footsteps Sounds as Biometric in Noisy Environments
(2022-08-03)Biometrics is the automated identification of a person based on distinctive characteristics, such as fingerprints, face, voice, or the sound of footsteps. This last characteristic has significant challenges considering the ... -
A Comparison between a Relational Database and a Graph Database in the context of a Personalized Cancer Treatment Application
(2016)This paper presents a performance comparison between a relational database (implemented in MySQL) and a graph database (implemented in Neo4j). Unlike traditional benchmarks, this comparison is made in the context of a real ... -
A first approach to acoustic characterization of Costa Rican children’s speech
(2020-03-27)As human interaction with computers becomes more pervasive, the value of developing automatic speech recognition, text-to-speech synthesis, and related speech technologies become more important for people of all ages, ... -
A genetic algorithm based framework for software effort prediction
(2017)Background: Several prediction models have been proposed in the literature using different techniques obtaining different results in different contexts. The need for accurate effort predictions for projects is one of the ... -
A mechano-biocatalytic one-pot approach to release sugars from lignocellulosic materials
(2020)A novel, mechano-biocatalytic one-pot process was developed by this study to efficiently release monosaccharides from lignocellulosic materials in an environmentally-friendly manner. The process synergistically integrates ... -
A mobile application that allows children in the early childhood to program robots
(2016)Children born in the Information Age are digital natives; this characteristic should be exploited to improve the learning process through the use of technology. This paper addresses the design, construction, and evaluation ... -
A Novel Control System for Medium-Voltage Hexverter-Based Drives
(2020-09-23)In this paper, a novel control system for the Hexverter-based drive is proposed and analysed. Unlike previously proposed control schemes, the proposed one does not require the information of the machine variables to ... -
A practical method for considering shading on photovoltaics systems energy yield
(2023-10-01)Along with the widespread adoption of solar energy, it is fundamental to develop methods and tools that help practitioners during the design phase of photovoltaic (PV) systems. Currently, multiple commercial software can ... -

(2017-06)This study focuses on system analysis of a self-sustaining high-strength wastewater treatment concept combining solar technologies, anaerobic digestion, and aerobic treatment to reclaim water. A solar bio-hybrid power ... -
A Strong-Motion Database of Costa Rica: 20 Years of Digital Records
(2020-09-09)In this article, we present a strong-motion database from earthquakes recorded by the Earthquake Engineering Laboratory at the University of Costa Rica. The database consists of 2471 three-component accelerograms from 155 ... -
A sustainable lignocellulosic biodiesel production integrating solar- and bio-power generation
(2016-06-04)A solar-bio-powered refining concept has been developed to establish sustainable lignocellulosic biodiesel production. The refining concept applies a combined hydrolysis process without detoxification to release sugars ... -
A user interaction bug analyzer based on image processing
(2016-08)Mobile applications support a set of user-interaction features that are independent of the application logic. Rotating the device, scrolling, or zooming are examples of such features. Some bugs in mobile applications can ... -
A Virtual Repository of Learning Objects to Support Literacy of SEN Children
(2015-01)Literacy development is an essential process for special education needs children. Otherwise, they will have additional difficulties in their daily life activities and hence their social inclusion. It is a big challenge ... -
Acceptance of Serious Games to Develop Digital Competencies in Higher Education
(2022)Serious games are the focus of the current research agenda. They show promise for allowing students to learn and practice skills. In fewer studies, they are used for the development of academic competencies. Therefore, it ... -
Aesthetics of Comfort: A Third Moment in Costa Rican Histories of Tropical Architecture
(2020)Histories of tropical architecture in Costa Rica could be constructed around three moments: the settlement of the United Fruit Company (UFCO) in 1889, the visit of Otto H. Koenigsberger, director of the Department of ... -
