1 Approximation of Complex μ

نویسنده

چکیده

The complex μ problem arises in robustness stability and robust performance problems where systems uncertainties and performance measures can be captured by the structure of D. This problem was first formally proposed by Doyle in 1982 [1] where the so-called D-scaling method was introduced for computing an upper bound for μ. Many simulation results have been conducted by Doyle and his colleagues to demonstrate that the D-scaling method provides good

Deriving Fuzzy Inequalities Using Discrete Approximation of Fuzzy Numbers

Most of the researches in the domain of fuzzy number comparisons serve the fuzzy number ordering purpose. For making a comparison between two fuzzy numbers, beyond the determination of their order, it is needed to derive the magnitude of their order. In line with this idea, the concept of inequality is no longer crisp however it becomes fuzzy in the sense of representing partial belonging or de...

Synthesis of Zinc Dimethyldithiocarbamate by Reductive Disulfide Bond Cleavage of Tetramethylthiuram Disulfide in Presence of Zn2+

The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...

Uniform λ−Adjustment and μ−Approximation in Banach Spaces

We introduce a new concept of perturbation of closed linear subspaces and operators in Banach spaces called uniform λ−adjustment which is weaker than perturbations by small gap, operator norm, q−norm, and K2−approximation. In arbitrary Banach spaces some of the classical Fredholm stability theorems remain true under uniform λ−adjustment, while other fail. However, uniformly λ−adjusted subspaces...

On multiplicative λ-approximations and some geometric applications

Let F be a set system over an underlying finite set X, and let μ be a nonnegative measure over X. I.e., for every S ⊆ X, μ(S) = ∑ x∈S μ(x). A measure μ ∗ on X is called a multiplicative λ-approximation of μ on (F , X) if for every S ∈ F it holds that aμ(S) ≤ μ∗(S) ≤ bμ(S), and b/a = λ ≥ 1. The central question raised and partially answered in the present paper is about the existence of meaningf...

An Experimental Assessment of the 2D Visibility Complex

We make an experimental assessment of the size of the 2D visibility complex of disjoint unit discs randomly distributed in the plane with density μ. We observe that the number of free bitangents is asymptotically linear in the number of discs and we study the dependence of the linear asymptote in terms of the density of the scene. Specifically, for a particular range of scene densities μ, we ex...
