Spatial pattern analysis using hybrid models: an application to the Hellenic seismicity
(Springer Verlag, 2017)
Earthquakes are one of the most destructive
natural disasters and the spatial distribution of their epi-
centres generally shows diverse interaction structures at
different spatial scales. In this paper, we use a ...
Wi-Fi Crowdsourced Fingerprinting Dataset for Indoor Positioning
(MDPI, 2017-10-03)
Benchmark open-source Wi-Fi fingerprinting datasets for indoor positioning studies are
still hard to find in the current literature and existing public repositories. This is unlike other research
fields, such as the image ...
Recommendation-Based Conceptual Modeling and Ontology Evolution Framework (CMOE+)
(Springer Verlag, 2017-08)
Within an enterprise, various stakeholders create different conceptual models, such as process, data, and requirements models. These models are fundamentally based on similar underlying enterprise (domain) concepts, but ...
Temporal stability on human activity recognition based on Wi-Fi CSI
(IEEE, 2023-12-06)
Over the last years, numerous studies have emerged using Wi-Fi channel state information, enabling device-free (passive) sensing for applications such as motion detection, indoor positioning or human activity recognition. ...
Measuring spatial inhomogeneity at different spatial scales using hybrids of Gibbs point process models
(Springer Verlag, 2016-05)
Infectious diseases give rise to complex spatial patterns exhibiting aggregation at different scales. Baddeley (J Stat Softw 55:1–43, 2013) proposed a technique for constructing new Gibbs models for spatial point patterns, ...
Citizen-Centric Data Services for Smarter Cities
(Elsevier, 2016-10-31)
Smart Cities use Information and Communication Technologies (ICT) to manage more efficiently the resources and services offered by a city and to make them more approachable to all its stakeholders (citizens, companies and ...
Effects of femtosecond laser and other surface treatments on the bond strength of metallic and ceramic orthodontic brackets to zirconia
(Public Library of Science, 2017)
Femtosecond laser has been proposed as a method for conditioning zirconia surfaces to
boost bond strength. However, metallic or ceramic bracket bonding to femtosecond lasertreated
zirconia surfaces has not been tested. ...
Equicontinuity criteria for metric-valued sets of continuous functions
(Elsevier, 2017)
Combining ideas of Troallic [1] and Cascales, Namioka, and Vera [2], we prove
several characterizations of almost equicontinuity and hereditarily almost equicontinuity
for subsets of metric-valued continuous functions ...
Parabolicity, Brownian Exit Time and Properness of Solitons of the Direct and Inverse Mean Curvature Flow
(2019-10-05)
We study some potential theoretic properties of homothetic solitons n of the MCF
and the IMCF. Using the analysis of the extrinsic distance function defined on these
submanifolds in Rn+m, we observe similarities and ...
First- and Second-Order Characteristics of Spatio-Temporal Point Processes on Linear Networks
(American Statistical AssociationInstitute of Mathematical StatisticsInterface Foundation of North AmericaTaylor and Francis, 2019-12-23)
We present several characteristics for spatio-temporal point patterns when the spatial locations are restricted to a linear network. A nonparametric kernel-based intensity estimator is proposed to highlight the concentration ...
