Networks, Volume 81, Issue 2, Page 204-219, March 2023., 2023 Abstract In this article, the Resource Constrained Clustered Shortest Path Tree Problem is defined. It generalizes the classic Resource Constrained Shortest Path Tree Problem since it is defined on an undirected, complete and weighted graph whose set of nodes is partitioned into clusters.

Machine‐Learned HASDM Thermospheric Mass Density Model With Uncertainty Quantification
Space Weather, Volume 20, Issue 4, April 2022., 2022 Abstract A thermospheric neutral mass density model with robust and reliable uncertainty estimates is developed based on the Space Environment Technologies (SET) High Accuracy Satellite Drag Model (HASDM) density database. This database, created by SET, contains 20 years of outputs from the U.S. Space Force's HASDM, which currently represents the state

30 Years of space–time covariance functions
WIREs Computational Statistics, Volume 13, Issue 2, March/April 2021., 2021 A separable covariance function (left) and a space‐time covariance function with dynamical compact support. Abstract In this article, we provide a comprehensive review of space–time covariance functions. As for the spatial domain, we focus on either the d‐dimensional Euclidean space or on the unit d‐dimensional sphere.

Caccioppoli-type inequalities for Dirac operators
Journal of Inequalities and Applications, 2022 In this paper, we establish the Caccioppoli estimates for the nonlinear differential equation − D ‾ ( | D v | p − 2 D v ) = λ | v | p − 2 v , 1 < p < ∞ , $$ - \overline{D}\bigl( \vert Dv \vert ^{p-2}Dv\bigr) = \lambda \vert v \vert ^{p-2}v, \quad 1< p ...

Sturmian comparison and oscillation theorems for quasilinear elliptic equations with mixed nonlinearities via Picone-type inequalityapplication/pdf A Picone-type inequality is established for quasilinear elliptic operators with mixed nonlinearities, and Sturmian comparison and oscillation theorems for quasilinear elliptic equations are derived by using the Picone-type inequality.

Engineering Reports, Volume 2, Issue 2, February 2020., 2020 An efficient explicit numerical model is proposed for the simulation of heat, air, and moisture transfer in porous material. The combination of innovative approaches enables to relax the numerical stability condition to reduce the computational time. Abstract This article proposes an efficient explicit numerical model with a relaxed stability condition

Weak Comparison Principle for Weighted Fractional p‐Laplacian Equation
Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020 The aim of this paper is to establish a weak comparison principle for a class fractional p‐Laplacian equation with weight. The nonlinear term f(x, s) > 0 is a Carathéodory function which is possibly unbounded both at the origin and at infinity and such that f(x, s)s1−p decreases with respect to s for a.e. x ∈ Ω.

A Network Coding‐Based Braided Multipath Routing Protocol for Wireless Sensor Networks
Wireless Communications and Mobile Computing, Volume 2019, Issue 1, 2019., 2019 In wireless sensor networks (WSNs), energy efficiency can simultaneously guarantee robustness to link loss and node failure and is a key design goal of routing protocols because WSNs are strongly constrained in terms of transmission reliability, transmission delay, and energy consumption.

Housing Affordability for Urban Regions
, 2021 Urban regions are recognised as driving forces of the global economy as well as the main sources of social inequality. In recent decades, particularly, housing access has become a serious problem, not only for the most disadvantaged population, but also ...
