A domain-independent methodology to analyze IoT data streams in real-time. A proof of concept implementation for anomaly detection from environmental data
(Taylor & Francis, 2016-07)
Pushed by the Internet of Things (IoT) paradigm modern sensor networks monitor a wide range of phenomena, in areas such as environmental monitoring, health care, industrial processes, and smart cities. These networks provide ...
An IoT Platform Based on Microservices and Serverless Paradigms for Smart Farming Purposes
(MDPI, 2020)
Nowadays, the concept of “Everything is connected to Everything” has spread to reach increasingly diverse scenarios, due to the benefits of constantly being able to know, in real-time, the status of your factory, your city, ...
Analysis of practical fractional vortex beams at far field
(Elsevier ScienceDirect, 2022-07-20)
The subject of calculating the topological charge (TC) or vortex strength of optical vortices has generated divided opinions among scientists. This is due to the fact that proper analytical results are hard to support from ...
Geospatial information infrastructures to address spatial needs in health: Collaboration, challenges and opportunities
(Elsevier, 2013)
Most health-related issues such as public health outbreaks and epidemiological threats are better understood from a spatial–temporal perspective and, clearly demand related geospatial datasets and services so that decision ...
The Euler Number from the Distance Function
(International Society for Stereology, 2013)
We present a new method to obtain the Euler number of a domain based on the tangent counts of concentric spheres in R3 (or circles in R2), with respect to the center O, that sweeps the domain. This method is derived from ...
A novel method for in-home Gait Speed estimation in Health Monitoring Using Bluetooth Low Energy
(IEEE, 2021)
Gait speed (GS) is a crucial parameter in the
evolution and diagnosis of degenerative illnesses. Nowadays, it is
measured in clinical environments where it is impossible to keep
track of all patients due to the lack of ...
Generalized Scalable Neighborhood Component Analysis for Single and Multi-Label Remote Sensing Image Characterization
(IEEE, 2021)
Deep metric learning has recently become a prominent technology for the semantic understanding ofremote sensing (RS)
scenes due to its great potential for characterizing visual semantics. However, state-of-the-art deep ...
Contextual contact tracing based on stochastic compartment modeling and spatial risk assessment
(Springer, 2021-10-26)
The current situation of COVID-19 highlights the paramount importance of infectious disease surveillance, which
necessitates early monitoring for effective response. Policymakers are interested in data insights identifying ...
