Asymptotic integration of a linear fourth order differential equation of Poincare type
(University Szeged, 2015)
This article deals with the asymptotic behavior of nonoscillatory solutions of fourth order linear differential equation where the coefficients are perturbations of constants. We define a change of variable and deduce that ...
Vector Lyapunov-like functions for multi-order fractional systems with multiple time-varying delays
(Elsevier, 2020)
In this paper, a general method to establish the asymptotic behaviour of solutions to multi-order multiple time-varying delays nonlinear systems is proposed. The method, relying on vector Lyapunov-like functions and on ...
Stabilization of a Boussinesq system of KdV–KdV type
(Elsevier B.V, 2008-08)
A family of Boussinesq systems has recently been proposed by Bona, Chen, and Saut in [J.L. Bona, M. Chen, J.-C. Saut, Boussinesq equations
and other systems for small-amplitude long waves in nonlinear dispersive media. ...
A comparison between traditional ordinary least-squares regression and three methods for enforcing additivity in biomass equations using a sample of Pinus radiata trees
(Scion, 2020)
Background: Additivity has long been recognised as a desirable property of systems of equations to predict the biomass of components and the whole tree. However, most tree biomass studies report biomass equations fitted ...
Design of a single window system for e-government services: the chilean casee
(American Institute of Mathematical Sciences, 2018-04)
The single window concept refers to systems that allow organizations to provide one-stop services to users. This paper describes a model for the design of a single window system in the context of e-government. The model ...
Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
Ion‐Exchange equilibria in cationic polyelectrolytes
(1994)
A method which allows the evaluation of phenomenological ion exchange constants Kex is proposed and tested in a cationic polyelectrolyte system. Results for nitrate/chloride exchange are nearly constant over the entire ...
Improving access to voting with optimized matchings
(Elsevier Ltd, 2018)
Research on political representation has traditionally focused on the design of electoral systems. Yet there is evidence that voting costs result in lower turnout and undermine voters’ confidence in the electoral system. ...
