Sharp bounds on the critical stability radius for relativistic charged spheres

, 2008
In a recent paper by Giuliani and Rothman \cite{GR}, the problem of finding a lower bound on the radius $R$ of a charged sphere with mass M and charge ...

Simple derivation of stability radius of multivariatesystems

Electronics Letters, 1997
The authors show that stability radii of discrete multivariate systems can be derived in a straightforward fashion by applying the maximum modulus principle for holomorphic functions of several complex variables.

Robust stability of patterned linear systems

Electronic Journal of Differential Equations, 2013
For a Hurwitz stable matrix $A\in \mathbb{R}^{n\times n}$, we calculate the real structured radius of stability for $A$ with a perturbation $P=B\Delta (t)C$, where $A, B, C$, $ \Delta (t)$ form a patterned quadruple of matrices; i.e., they are ...

Highway designs: effects of heavy vehicles stability

Dyna, 2018
From the perspective of heavy vehicles stability, some criteria of stability should be adhered to highway designs. In particular, the relationship between minimum radius, superelevation, slope angle, side friction, and design speed should be re-evaluated.

Magnetic resonance imaging offers advantages over computer tomography for measurement of the shoulder stability ratio

Journal of Experimental Orthopaedics
Purpose Recent studies indicate that bony shoulder stability ratio (BSSR) is a useful parameter for estimating glenohumeral stability provided by concavity‐compression.

Continuity properties of the lower spectral radius

, 2014
The lower spectral radius, or joint spectral subradius, of a set of real $d \times d$ matrices is defined to be the smallest possible exponential growth rate of long products of matrices drawn from that set.

Magnetic Interaction and X-Ray Absorption of the Magnetic Compact Stars [PDF]

Journal of Astronomy and Space Sciences, 1993
Using a simple analytic model based on the MHD stability arguments we obtain the size of the magnetosphere for the magnetic compact stars. We assume the ordered, fieldaligned flow in the magnetosphere and estimate the wellknown Alfven radius.
