Validation of the Accuracy and Convergence Time of Real Time Kinematic Results Using a Single Galileo Navigation System [PDF]

open access: yesSensors, 2018
For the last two decades, the American GPS and Russian GLONASS were the basic systems used in global positioning and navigation. In recent years, there has been significant progress in the development of positioning systems.

Convergence time towards periodic orbits in discrete dynamical systems. [PDF]

open access: yesPLoS One, 2014
We investigate the convergence towards periodic orbits in discrete dynamical systems. We examine the probability that a randomly chosen point converges to a particular neighborhood of a periodic orbit in a fixed number of iterations, and we use ...

Uniform Statistical Convergence on Time Scales [PDF]

open access: yesJournal of Applied Mathematics, 2014
We will introduce the concept of m- and (λ,m)-uniform density of a set and m- and (λ,m)-uniform statistical convergence on an arbitrary time scale. However, we will define m-uniform Cauchy function on a time scale. Furthermore, some relations about these

Uniform Lacunary Statistical Convergence on Time Scales

open access: greenInternational Journal of Analysis and Applications, 2017
We introduce (θ,m)-uniform lacunary density of any set and (θ,m)-uniform lacunary statistical convergence on an arbitrary time scale. Moreover, (θ,m)-uniform strongly p-lacunary summability and some inclusion relations about these new concepts are also ...

Chip-Scale Ultra-Low Field Atomic Magnetometer Based on Coherent Population Trapping

open access: yesSensors, 2021
We report a chip-scale atomic magnetometer based on coherent population trapping, which can operate near zero magnetic field. By exploiting the asymmetric population among magnetic sublevels in the hyperfine ground state of cesium, we observe that the ...

Dynamic Trust-Based Device Legitimacy Assessment Towards Secure IoT Interactions

open access: yesJournal of Communications Software and Systems, 2022
Establishing trust-based interactions in heterogeneously connected devices appears to be the prominent mechanism in addressing the prevailing concerns of confidence, reliability and privacy relevant in establishing secure interactions among connected ...

Stopping Times and Γ-Convergence [PDF]

open access: yesTransactions of the American Mathematical Society, 1987
The equation ∂ u / ∂ t = Δ u − μ u \partial u/\partial t = \Delta u - \mu u represents diffusion with killing. The strength of the killing is described by the measure μ \mu , which is not assumed to be finite or even σ

Finite-Time Convergent Gossiping [PDF]

open access: yesIEEE/ACM Transactions on Networking, 2016
Gossip algorithms are widely used in modern distributed systems, with applications ranging from sensor networks and peer-to-peer networks to mobile vehicle networks and social networks. A tremendous research effort has been devoted to analyzing and improving the asymptotic rate of convergence for gossip algorithms.

RM-ADR: Resource Management Adaptive Data Rate for Mobile Application in LoRaWAN

open access: yesSensors, 2021
LoRaWAN is renowned and a mostly supported technology for the Internet of Things, using an energy-efficient Adaptive Data Rate (ADR) to allocate resources (e.g., Spreading Factor (SF)) and Transmit Power (TP) to a large number of End Devices (EDs).

Evaluation of Inter-System Bias between BDS-2 and BDS-3 Satellites and Its Impact on Precise Point Positioning

open access: yesRemote Sensing, 2020
The BeiDou navigation satellite system (BDS) currently has 41 satellites in orbits and will reach its full constellation following the launch of the last BDS satellite in June 2020 to provide navigation, positioning, and timing (PNT) services for global ...
