The gap between necessity and sufficiency for stability of sparse matrix systems: simulation studies
… Such systems’ stability can be determined by the Routh-Hurwitz criterion. However, simply using the Routh-Hurwitz criterion is not efficient in this kind of system. Therefore, a necessary condition can save a lot of work. The necessary condition is of importance and will be discussed in this …

On Modeling HIV Infection Of Cd4+ T Cells
… are examined utilizing standard methods and the Routh-Hurwitz criteria. We show that if N, the number of infectious virions produced per actively infected T cell, is less than a critical value, , then the uninfected state is the only steady state in the non negative orthant, and this state is …

System modeling and control design of a two-stage metering poppet-valve system
… for selecting control gains are derived by Routh-Hurwitz method. Finally, important system parameters, especially the transient flow force and two leakages, are discussed to reveal their effects on the open-loop system stability. Simulations results illustrate that the closed-loop poppet …

Energy methods for lossless systems using quadratic differential forms
… tests for linear systems, and we also give a new Routh-Hurwitz like stability test.

A Three Dimensional Model of Virus Dynamics in HIV Patients
… point P<sub>1</sub> is established using the Routh-Hurwitz conditions and the global stability of P<sub>1</sub> is then evaluated numerically. The mathematical results show that when N > N<sub><em>c</em></sub> the solutions always converge to an endemically infected steady state. Thus the …

Mathematical Models of Biochemical Oscillations
The goal of this paper is to explain the mathematics involved in modeling biochemical oscillations. We first discuss several important biochemical concepts fundamental to the construction of descriptive mathematical models. We review the basic theory of differential equations and stability analysis …

Control de minicentrales hidroeléctricas fluyentes : modelado y estabilidad
… matriz y aplicando el criterio de estabilidad de Routh-Hurwitz se puede llegar a las siguientes conclusiones: Centrales en derivación con canal y centrales a pie de presa: Las dimensiones de la cámara de carga y del azud de derivación no influyen en la estabilidad de la central. Se mejora la …
