Optimal Approximation of Fractional-Order Butterworth Filter Based on Weighted Sum of Classical Butterworth Filters

open access: yesIEEE Access, 2021
In this paper, a new two-steps design strategy is introduced for the optimal rational approximation of the fractional-order Butterworth filter. At first, the weighting factors of the summation between the ${n}^{\text {th}}$ -order and the $(n + 1 ...

Strong solutions for singular Dirichlet elliptic problems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
We prove an existence result for strong solutions $u\in W^{2,q}\left(\Omega\right) $ of singular semilinear elliptic problems of the form $-\Delta u=g\left( \cdot,u\right) $ in $\Omega,$ $u=\tau$ on $\partial\Omega,$ where ...

Multi-Robot Routing Problem with Min–Max Objective

open access: yesRobotics, 2021
In this paper, we study the “Multi-Robot Routing problem” with min–max objective (MRR-MM) in detail. It involves the assignment of sequentially ordered tasks to robots such that the maximum cost of the slowest robot is minimized. The problem description,

Coupling of the synchronization stations of an Extended Kanban system [PDF]

open access: yesEAI Endorsed Transactions on Industrial Networks and Intelligent Systems, 2015
In this paper, an approximate method for estimating the performance of the synchronization stations of an ExtendedKanban production system is developed. The correct treatment of an Extended Kanban system requires the decompositionof the system into a set
