Archetypal contour shapes
(Università di Cassino e del Lazio Meridionale. Centro Editoriale di Ateneo, 2019)
Shapes are represented by contour functions from planar object outlines. Functional archetypal analysis is proposed to describe closed contour shapes.
Each contour function is approximated by a convex combination of ...
Spatio‐temporal classification in point patterns under the presence of clutter.
(Wiley, 2019-08-23)
We consider the problem of detection of features in the presence of clutter forspatio-temporal point patterns. In previous studies, related to the spatial context,Kth nearest-neighbor distances to classify points between ...
On using Reproducing Kernel Hilbert Spaces for the analysis of Replicated Spatial Point Processes
(Elsevier, 2023)
This paper focuses on the use of the theory of Reproducing
Kernel Hilbert Spaces in the statistical analysis of replicated point
processes. We show that spatial point processes can be observed
as random variables in a ...
Representation of group isomorphisms I
(Elsevier, 2019-08-15)
Let G be a metric group and let Aut(G) denote the automorphism group
of G. If A and B are groups of G-valued maps defined on the sets X and Y , respec-
tively, we say that A and B are equivalent if there is a group ...
Powers of conjugacy classes in a finite group
(Springer, 2019)
The aim of this paper is to show how the number of conjugacy classes appearing in the product of classes affect the structure of a finite group. The aim of this paper was to show several results about solvability concerning ...
A note on the Baker–Campbell–Hausdorff series in terms of right-nested commutators
(Springer, 2021-01-27)
We get compact expressions for the Baker–Campbell–Hausdorff
series Z = log(eX eY ) in terms of right-nested commutators. The reduction in the number of terms originates from two facts: (i) we use as a
starting point an ...
Inhomogeneous higher-order summary statistics for point processes on linear networks
(Springer, 2020)
As a workaround for the lack of transitive transformations on linear network structures, which are required to consider different notions of distributional invariance, including stationarity, we introduce the notions of ...
Stochastic smoothing of point processes for wildlife-vehicle collisions on road networks (Epub ahead of print)
(Springer, 2021-09-04)
Wildlife-vehicle collisions on road networks represent a natural problem between human populations and the environment, that affects wildlife management and raise a risk to the life and safety of car drivers. We propose a ...
Quality of life, big data and the power of statistics
(Elsevier, 2018)
The digital era has opened up new possibilities for data-driven research. This paper
discusses big data challenges in environmental monitoring and reflects on the use of
statisticalmethodsintacklingthesechallengesforim ...
Challenges Regarding Scientific Transcription in Virtual Office Hours
(MDPI, 2021-03-24)
Mathematics teachers face great difficulties during virtual communication with their
students, mainly because scientific and technical subjects use a great many mathematical symbols,
abstract objects and a wide variety ...
