Warped Supersymmetric Radius Stabilization

, 2004
A simple model of extra-dimensional radius stabilization in a supersymmetric Randall-Sundrum model is presented. In our model, we introduce only a bulk hypermultiplet and source terms on each boundary branes. With an appropriate choice of model parameters, we find that the radius can be stabilized by supersymmetric vacuum conditions.

Sensitivity analysis of efficient solution in vector MINMAX boolean programming problem [PDF]

Computer Science Journal of Moldova, 2002
We consider a multiple criterion Boolean programming problem with MINMAX partial criteria. The extreme level of independent perturbations of partial criteria parameters such that efficient (Pareto optimal) solution preserves optimality was obtained.

Robust Stability and Robust Stabilization of Discrete-Time Markov Jump Linear Systems Under a Class of Stochastic Structured Nonlinear Uncertainties

Entropy
Robust stability/stabilization for discrete-time time-varying Markovian jump linear systems subject to block-diagonal stochastic parameter perturbations is addressed in this paper. Using a scaling technique, we succeed in effectively addressing the multi-

Stability of an Exciton bound to an Ionized Donor in Quantum Dots

, 2002
Total energy, binding energy, recombination rate (of the electron hole pair) for an exciton (X) bound in a parabolic two dimensional quantum dot by a donor impurity located on the z axis at a distance d from the dot plane, are calculated by using the ...

On the nonlinearly structured stability radius problem [PDF]

Proceedings of the 1998 American Control Conference. ACC (IEEE Cat. No.98CH36207), 1998
This paper considers the problem of finding a perturbation matrix with the least spectral norm such that a matrix-valued function becomes singular, where the dependence of the function on the perturbation is allowed to be nonlinear. It is proved that such a problem can be approximated by a smooth unconstrained minimization problem with compact sublevel

Accuracy and Stability of Computing High-Order Derivatives of Analytic Functions by Cauchy Integrals [PDF]

, 2010
High-order derivatives of analytic functions are expressible as Cauchy integrals over circular contours, which can very effectively be approximated, e.g., by trapezoidal sums.

Extending stability through hierarchical clusters in Echo State Networks

Frontiers in Neuroinformatics, 2010
Echo State Networks (ESN) are reservoir networks that satisfy well-established criteria for stability when constructed as feedforward networks. Recent evidence suggests that stability criteria are altered in the presence of reservoir substructures, such ...

Absolute Stability Limit for Relativistic Charged Spheres

, 2007
We find an exact solution for the stability limit of relativistic charged spheres for the case of constant gravitational mass density and constant charge density. We argue that this provides an absolute stability limit for any relativistic charged sphere

On stability in game problems of finding Nash set [PDF]

Computer Science Journal of Moldova, 2005
A finite game of several players in the case of linear payoff functions is considered. Stability of the problem of finding the set of Nash equilibrium situations is investigated.

Bridging transitions for spheres and cylinders

, 2015
We study bridging transitions between spherically and cylindrically shaped particles (colloids) of radius $R$ separated by a distance $H$ that are dissolved in a bulk fluid (solvent).
