A new weighting factor in combining belief function. [PDF]

open access: yesPLoS ONE, 2017
Dempster-Shafer evidence theory has been widely used in various applications. However, to solve the problem of counter-intuitive outcomes by using classical Dempster-Shafer combination rule is still an open issue while fusing the conflicting evidences ...

Weighted biharmonic green functions for rational weights [PDF]

open access: yesGlasgow Mathematical Journal, 1999
This paper deals with weighted biharmonic operators of the form \(\Delta|P'|^2\Delta\) on the unit disc, where \(\Delta\) is the Laplacian and \(P\) is a rational function. The existence of the Green function for this operator is established for any rational function \(P\), and an algorithm is provided for obtaining it (by solving a certain system of ...

Modelling transient pipe flow with cavitation and frequency dependent friction. Part II. Friction and numerical-experimental validation [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2015
Modelling of time-depended hydraulic friction is not an easy issue. As numerous studies have shown, wall shear stress in the pipe can be determined as a sum of the quasi-steady and time-dependent expressions.

A weighted Möbius function

open access: yesDiscrete Mathematics, 2017
For a fixed odd prime $\ell$, we define a variant of the classical Möbius function on the poset of isomorphism classes of finite abelian $\ell$-groups, then we prove an analog of Hall's theorem on the vanishing of the Möbius function.

A Weight Sequence Distance Function [PDF]

open access: yes, 2013
In this paper, a family of weighted neighborhood sequence distance functions defined on the square grid is presented. With this distance function, the allowed weight between any two adjacent pixels along a path is given by a weight sequence. We build on our previous results, where only two or three unique weights are considered, and present a framework

An Effective Model Predictive Control Method With Self-Balanced Capacitor Voltages for Single-Phase Three-Level Shunt Active Filters

open access: yesIEEE Access, 2021
This paper presents an effective model predictive control (MPC) method for single-phase three-level T-type inverter-based shunt active power filters (SAPFs). The SAPF using T-type inverter topology has not been reported in the literature yet. Contrary to
