Large time behavior of weakly coupled systems of first-order Hamilton-Jacobi equations [PDF]

, 2011
We show a large time behavior result for class of weakly coupled systems of first-order Hamilton-Jacobi equations in the periodic setting. We use a PDE approach to extend the convergence result proved by Namah and Roquejoffre (1999) in the scalar case ...

Self-consistent solutions to the intersubband rate equations in quantum cascade lasers: Analysis of a GaAs/AlxGa1-xAs device [PDF]

, 2001
The carrier transition rates and subband populations for a GaAs/AlGaAs quantum cascade laser operating in the mid-infrared frequency range are calculated by solving the rate equations describing the electron densities in each subband self-consistently.

On certain equations and inequalities involving the arithmetical functions φ(n) and d(n) – II [PDF]

Notes on Number Theory and Discrete Mathematics, 2023
In papers [3] and [5] we have studied certain equations and inequalities involving the arithmetical functions φ(n) and d(n). In this paper we will consider some other equations. Some open problems will be stated, too.

Introduction of an Auxiliary Breaker into the Generator-Transformer Block for Energy Saving in Open Switchgear Circuits of Power Plants

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2023
A need in finding of new ways of energy saving at open switchgears of power plants is substantiated. In order to increase energy saving efficiency, an auxiliary breaker is suggested to be inserted between a transformer of a block and its two high-voltage

Entropy Solution Theory for Fractional Degenerate Convection-Diffusion Equations [PDF]

, 2010
We study a class of degenerate convection diffusion equations with a fractional nonlinear diffusion term. These equations are natural generalizations of anomalous diffusion equations, fractional conservations laws, local convection diffusion equations ...

Modelling the tree height-diameter relationship of Macedonian pine (Pinus peuce Gris.) forests in North Macedonia

Journal of Forest Science, 2023
The most crucial individual tree variables in forest management are diameter at breast height (DBH) and height of trees (H). Projection of stand development over time relies on accurate height-diameter functions.

On the discrete and continuous Miura Chain associated with the Sixth Painlevé Equation [PDF]

, 1999
A Miura chain is a (closed) sequence of differential (or difference) equations that are related by Miura or B\"acklund transformations. We describe such a chain for the sixth Painlev\'e equation (\pvi), containing, apart from \pvi itself, a Schwarzian ...
