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 ...
Succinct Data Structures in the Realm of GIS
(MDPI, 2021)
[Abstract] Geographic Information Systems (GIS) have spread all over our technological environment in the last decade. The inclusion of GPS technologies in everyday portable devices along with the creation of massive ...
Tool for SPARQL Querying over Compact RDF Representations
(MDPI, 2021)
[Abstract] We present an architecture for the efficient storing and querying of large RDF datasets. Our approach seeks to store RDF datasets in very little space while offering complete SPARQL functionality. To achieve ...
Towards a Semi-Automated Data-Driven Requirements Prioritization Approach for Reducing Stakeholder Participation in SPL Development
(MDPI, 2021)
[Abstract] Requirements prioritization (RP), part of Requirements engineering (RE), is an essential activity of Software Product-Lines (SPL) paradigm. Similar to standard systems, the identification and prioritization of ...
Space-Efficient Representations of Raster Time Series
(Elsevier, 2021)
[Abstract] Raster time series, a.k.a. temporal rasters, are collections of rasters covering the same region at consecutive timestamps. These data have been used in many different applications ranging from weather forecast ...
Take one for the team: on the time efficiency of application-level buffer-aided relaying in edge cloud communication
(Springer, 2021-03-12)
[Abstract]
Background
Adding buffers to networks is part of the fundamental advance in data communication. Since edge cloud computing is based on the heterogeneous collaboration network model in a federated environment, ...
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 ...
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), ...
An Efficient Representation of Enriched Temporal Trajectories
(SciTePress, 2021)
[Abstract] We present a novel representation of enriched trajectories of a mobile workforce management system. In this system, employees are tracked during their working day and both their routes and the tasks performed ...
Lossless Compression of Industrial Time Series With Direct Access
(Elsevier, 2021)
[Abstract] The new opportunities generated by the data-driven economy in the manufacturing industry have causedmany companies opt for it. However, the size of time series data that need to be captured creates theproblem ...
