GNSS RTK Positioning Augmented with Large LEO Constellation
Remote Sensing, 2019 It is widely known that in real-time kinematic (RTK) solution, the convergence and ambiguity-fixed speeds are critical requirements to achieve centimeter-level positioning, especially in medium-to-long baselines.

Impact of Number of Artificial Ants in ACO on Network Convergence Time: A Survey
International Journal of Informatics, Information System and Computer Engineering, 2022 Due to the dynamic nature of computer networks today, there is need to make the networks self-organized. Selforganization can be achieved by applying intelligent systems in the networks to improve convergence time. Bio-inspired algorithms that imitate

Convergence of the empirical spectral measure of unitary Brownian motion [PDF]
, 2018 Let $\{U^N_t\}_{t\ge 0}$ be a standard Brownian motion on $\mathbb{U}(N)$. For fixed $N\in\mathbb{N}$ and $t>0$, we give explicit bounds on the $L_1$-Wasserstein distance of the empirical spectral measure of $U^N_t$ to both the ensemble-averaged spectral

Convergent iterative schemes for time parallelization [PDF]
Mathematics of Computation, 2006 Summary: Parallel methods are usually not applied to the time domain because of the inherit sequentialness of time evolution. But for many evolutionary problems, computer simulation can benefit substantially from time parallelization methods. In this paper, we present several such algorithms that actually exploit the sequential nature of time evolution
