Evaluation of LoRaWAN’s Static and Dynamic Capabilities and its Limitations for IoT Applications
Proceedings of the International Conference on Applied Innovations in IT, 2023 This paper is a study of connection parameters of Long Range Wide Area Networks (LoRaWAN) for reliable and robust data communication. It also seeks to highlight the limitations and shortcomings of the LoRaWAN technology, with the goal of identifying ...

Fire behaviors along timber linings affixed to tunnel walls in mines.
PLoS ONE, 2021 Timber linings are applied as primary supports in the tunnel fault and fracture zones of mines. These linings are essential to prevent broken rock from falling during the occurrence of exogenous fires. In this study, experiments and numerical simulations

Spreading speeds and spreading sets of reaction-diffusion equations
, 2021 This paper deals with the large time dynamics of bounded solutions of reaction-diffusion equations with unbounded initial support in $\mathbb{R}^N$. We prove a variational formula for the spreading speeds in any direction, and we also describe the asymptotic shape of the level sets of the solutions at large time.

Numerical simulation of spreading drops [PDF]
, 2013 We consider a liquid drop that spreads on a wettable surface. Different time evolutions have been observed for the base radius r depending of the relative role played by inertia, viscosity, surface tension and the wetting condition. Numerical simulations

Spreading Speeds of Nonlocal KPP Equations in Heterogeneous Media [PDF]
Acta Mathematica Sinica, English Series, 2022 In this paper, we prove the existence of the spreading speed of nonlocal KPP equations in two cases: 1. The media is almost periodic and the kernel of diffusion is continuous; 2. The media is periodic and the diffusion is not continuous but weak irreducible.

Generational Spreading Speed and the Dynamics of Population Range Expansion [PDF]
The American Naturalist, 2015 Some of the most fundamental quantities in population ecology describe the growth and spread of populations. Population dynamics are often characterized by the annual rate of increase, λ, or the generational rate of increase, R0. Analyses involving R0 have deepened our understanding of disease dynamics and life-history complexities beyond that afforded

On the Speed of Spread for Fractional Reaction‐Diffusion Equations [PDF]
International Journal of Differential Equations, 2009 The fractional reaction diffusion equation ∂tu + Au = g(u) is discussed, where A is a fractional differential operator on ℝ of order α ∈ (0, 2), the C1 function g vanishes at ζ = 0 and ζ = 1, and either g ≥ 0 on (0, 1) or g < 0 near ζ = 0. In the case of nonnegative g, it is shown that solutions with initial support on the positive half axis spread ...
