A spatial pattern analysis of the halophytic species distribution in an arid coastal environment
(Springer Verlag, 2015)
Obtaining information about the spatial distribution of desert plants is considered as a serious challenge for ecologists and environmental modeling due to the required intensive field work and infrastructures in harsh and ...
Spatio-temporal stochastic modelling of environmental hazards
(Copyright © 2015 Elsevier, 2015-09)
This is the editorial letter for the Special Issue dedicated to the joint VII International Workshop on Spatio-temporal Modelling (METMAVII) and the 2014 meeting of the research group for Statistical Applications to ...
Enabling Geospatial Context in an IoT Decentralised Reputation Management System using Ethereum Smart Contracts
(IEEE, 2021)
Social Internet of Things (SIoT) is a concept that integrates the Internet of Things and human social networks. An SIoT system has to store and manage device reputation values, which are used by end devices to determine ...
Unsupervised detection of transitions at home by using BLE technology
(IEEE, 2021-11)
This paper presents a set of unsupervised methods based on Bluetooth Low Energy (BLE) technology to obtain the position and transitions that users perform between the zones where they usually stay longer in their own homes. ...
Second-order smoothing of spatial point patterns with small sample sizes: a family of kernels
(Springer Verlag, 2015-01)
We consider kernel-based non-parametric estimation of second-order product densities of spatial point patterns. We present a new family of optimal and positive kernels that shows less variance and more flexibility than ...
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 ...
Risk factors and spatial distribution of urban rat infestations
(Springer Verlag, 2014-03)
Urban rat infestations have multifactorial causes and may result in severe public health and environmental problems, as well as heavy economic losses. The identification of putative environmental determinants of urban rat ...
A note on smoothness measures for space-time surfaces
(Springer Verlag, 2013-09)
The differentiability of a random field has a direct relationship with the differentiability of its covariance function. We review the concept of differentiability of space–time covariance models and random fields, and its ...
A new extrinsic sample mean in the shape space with applications to the boundaries of anatomical structures
(Wiley, 2016-02-16)
Shape analysis is of great importance in many fields of medical imaging and computational biology. In this paper, we consider the shape space as the set of smooth planar immersed curves in inline image (parameterized curves) ...
Towards Accelerated Localization Performance Across Indoor Positioning Datasets
(IEEE, 2022)
The localization speed and accuracy in the indoor scenario can greatly impact the Quality of Experience of the user. While many individual machine learning models can achieve comparable positioning performance, their ...
