Parabolic Minkowski convolutions of viscosity solutions to fully nonlinear equations [PDF]
, 2019 This paper is concerned with the Minkowski convolution of viscosity solutions of fully nonlinear parabolic equations. We adopt this convolution to compare viscosity solutions of initial-boundary value problems in different domains.

Unbounded Viscosity Solutions of Hybrid Control Systems [PDF]
, 2008 We study a hybrid control system in which both discrete and continuous controls are involved. The discrete controls act on the system at a given set interface.

Factors influencing rheological properties of plugging agent particle solutions
Youqi dizhi yu caishoulu, 2023 The effect of the thermal composite fluid remaining in the reservoirs on the rheological properties of the plugging agent particle solution is still unclear at the late thermal composite development stage of the heavy oil reservoirs. Therefore， it limits

Viscosity solutions to degenerate Complex Monge-Amp\`ere equations [PDF]
, 2010 We develop an alternative approach to Degenerate complex Monge-Amp\`ere equations on compact K\"ahler manifolds based on the concept of viscosity solutions and compare systematically viscosity concepts with pluripotential theoretic ones. We generalize to

Balanced-Viscosity solutions for multi-rate systems [PDF]
, 2014 Several mechanical systems are modeled by the static momentum balance for the displacement $u$ coupled with a rate-independent flow rule for some internal variable $z$. We consider a class of abstract systems of ODEs which have the same structure, albeit

Resistive and viscous dynamics of finite-amplitude shear waves at a magnetic X-point [PDF]
, 2005 The dynamics and dissipation of axial shear waves, superposed on a planar magnetic X-point in a resistive viscous incompressible plasma, are analyzed numerically and analytically. The interplay of viscous and resistive effects is demonstrated by deriving

Optimal Exploitation of a General Renewable Natural Resource under State and Delay Constraints
Mathematics, 2020 In this work, we study an optimization problem arising in the management of a natural resource over an infinite time horizon. The resource is assumed to evolve according to a logistic stochastic differential equation.

The Gelfand problem for the 1-homogeneous p-Laplacian
Advances in Nonlinear Analysis, 2017 In this paper, we study the existence of viscosity solutions to the Gelfand problem for the 1-homogeneous p-Laplacian in a bounded domain Ω⊂ℝN{\Omega\subset\mathbb{R}^{N}}, that is, we deal ...

Effect of thickening agents on perceived viscosity and acidity of model beverages
Czech Journal of Food Sciences, 2012 The effect of thickening agents - methyl cellulose, hydroxyethyl cellulose, sodium carboxymethyl cellulose, and xanthan gum - solutions on the sensory viscosity was investigated in the concentration range of 0-0.8%.
