Design of Mutation Operators for Testing Geographic Information Systems
(M D P I AG, 2019-08-06)
[Abstract] In this article, we propose the definition of specific mutation operators for testing Geographic Information Systems. We describe the process for applying the operators and generating mutants, and present a case ...
Space/time-efficient RDF stores based on circular suffix sorting
(Springer Nature, 2023-03)
[Abstract]: The resource description framework (RDF) has gained popularity as a format for the standardized publication and exchange of information in the Web of Data. In this paper, we introduce RDFCSA, a compressed ...
Compressed and queryable self-indexes for RDF archives
(Springer Nature, 2023-08)
[Abstract]: RDF compression and querying are consolidated topics in the Web of Data, with a plethora of solutions to efficiently store and query static datasets. However, as RDF data changes along time, it becomes necessary ...
Managing Compressed Structured Text
(Springer Nature, 2018-12-07)
[Definition]: Compressing structured text is the problem of creating a reduced-space representation from which the original
data can be re-created exactly. Compared to plain text compression, the goal is to take advantage ...
Revisiting Compact RDF Stores Based on k2-Trees
(IEEE Xplore, 2020-03)
[Abstract]: We present a new compact representation to efficiently store and query large RDF datasets in main memory. Our proposal, called BMatrix, is based on the k 2 -tree, a data structure devised to represent binary ...
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 ...
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 ...
An index for moving objects with constant-time access to their compressed trajectories
(Taylor & Francis, 2021)
[Abstract]: As the number of vehicles and devices equipped with GPS technology has grown explosively, an urgent need has arisen for time- and space-efficient data structures to represent their trajectories. The most commonly ...
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 ...
Augmented Thresholds for MONI
(Institute of Electrical and Electronics Engineers Inc., 2023)
[Abstract]: MONI (Rossi et al., 2022) can store a pangenomic dataset T in small space and later, given a pattern P, quickly find the maximal exact matches (MEMs) of P with respect to T. In this paper we consider its one-pass ...
