Kriging with external drift for functional data for air quality monitoring
(Springer Verlag, 2014-07)
Functional data featured by a spatial dependence structure occur in many environmental sciences when curves are observed, for example, along time or along depth. Recently, some methods allowing for the prediction of a curve ...
DBIG-US: A two-stage under-sampling algorithm to face the class imbalance problem
(Elsevier, 2020-11-12)
The class imbalance problem occurs when one class far outnumbers the other classes, causing most traditional classifiers perform poorly on the minority classes. To tackle this problem, a plethora of techniques have been ...
A Location Aware Mobile Tool for Direct and Indirect Climate Data Sensors
(Wiley, 2014-06)
Access to GIS data from mobile platforms continues to be a challenge and there is a wide range of fields where it is extremely useful. In this work, we combined three key aspects: climate data sensors, mobile platforms and ...
A Survey on Wearable Technology: History, State-of-the-Art and Current Challenges
(Elsevier, 2021-04-08)
Technology is continually undergoing a constituent development caused by the appearance of billions new interconnected “things” and their entrenchment in our daily lives. One of the underlying versatile technologies, namely ...
Significance tests for covariate-dependent tredns in inhomogeneous spatio-temporal point processes
(Springer Verlag, 2014-03)
Modeling and inference for spatial and spatio-temporal point processes is an issue that has been broadly investigated in the last years. Application fields such as forestry, epidemiology and ecology have been the main ...
Femtosecond laser micromachining with extended depth of focus by using diffractive lenses
(Elsevier, 2014-06-01)
We show that a simple diffraction focusing element can alleviate mechanical tolerances in ultrafast laser microprocessing. In particular, we experimentally demonstrate that, in comparison with a conventional refractive ...
A bias correction function for classification performance assessment in two-class imbalanced problems
(Elsevier, 2014)
This paper introduces a framework that allows to mitigate the impact of class imbalance on most scalar performance measures when used to evaluate the behavior of classifiers. Formally, a correction function is defined with ...
A comparative study in the standardisation of IoT devices using geospatial web standards
(Institute of Electrical and Electronics EngineersIEEE, 2020-10-15)
Although billions of devices are embedded in the World Wide Web through the Internet of Things, there is still a lack of a common, interoperable way to connect them and make them interact seamlessly. IoT has also found its ...
Statistical significance of normalized global alignment
(2015-07-01)
The comparison of homologous proteins from different species is a first step toward a function assignment and a reconstruction of the species evolution. Though local alignment is mostly used for this purpose, global alignment ...
Three Dimensional Visualization of Long Range Scenes by Photon Counting Mid-Wave Infrared Integral Imaging
(2015-07-03)
Integral Imaging under photon counting conditions has found different three-dimensional (3D) imaging applications, including 3D image reconstruction and recognition. In this letter, we present the application of the maximum ...
