Particle boards produced from cassava stalks: Evaluation of physical and mechanical properties

open access: yesSouth African Journal of Science, 2015
We investigated the potential use of cassava stalks for the production of bonded particle boards. Particle boards were produced from cassava stalks using urea-formaldehyde as a binder.

Orbital stability via the energy-momentum method: the case of higher dimensional symmetry groups [PDF]

open access: yes, 2018
We consider the orbital stability of relative equilibria of Hamiltonian dynamical systems on Banach spaces, in the presence of a multi-dimensional invariance group for the dynamics.

Stochastic Stability Analysis of Discrete Time System Using Lyapunov Measure

open access: yes, 2016
In this paper, we study the stability problem of a stochastic, nonlinear, discrete-time system. We introduce a linear transfer operator-based Lyapunov measure as a new tool for stability verification of stochastic systems.

Three-dimensional stability of the solar tachocline [PDF]

open access: yes, 2005
The three-dimensional, hydrodynamic stability of the solar tachocline is investigated based on a rotation profile as a function of both latitude and radius.

Accelerated swelling of wood for rapid dimensional stability

open access: yesActa Scientiarum: Technology, 2022
Dimensional stability of wood can be determined by measuring the total swelling percentage between 0% and FSP moisture content according to the ABNT NBR 7190 (Associação Brasileira de Normas Técnicas [ABNT], 1997).

Three-dimensional stability of Burgers vortices

open access: yes, 2010
Burgers vortices are explicit stationary solutions of the Navier-Stokes equations which are often used to describe the vortex tubes observed in numerical simulations of three-dimensional turbulence.

Structure and Stability of the One-Dimensional Mapper [PDF]

open access: yesFoundations of Computational Mathematics, 2017
Given a continuous function $f: X\longrightarrow \mathbb{R}$ and a cover $\mathcal{I}$ of its image by intervals, the Mapper is the nerve of a refinement of the pullback cover $f^{-1}(\mathcal{I})$. This paper introduces a theoretical framework that establishes a correspondence between the Mapper to one of the Reeb graphs, which makes it possible to ...

A Study to Evaluate and Compare the Dimensional Stability of Aluwax upon Moist Heat and Dry Heat Treatment at Different Time Intervals

open access: yesJournal of Orofacial Sciences, 2022
Introduction: The key to a successful prosthesis is the accurate transfer of the maxillo–mandibular relationship to an articulator.Evaluating and comparing the dimensional stability of Aluwax upon moist heat and dry heat treatment at different time ...

Selection theorem for systems with inheritance

open access: yes, 2007
The problem of finite-dimensional asymptotics of infinite-dimensional dynamic systems is studied. A non-linear kinetic system with conservation of supports for distributions has generically finite-dimensional asymptotics.
