The sensitivity of generalized matrix Lyapunov equations relative to perturbations in the coefficient matrices is studied. New local and non-local perturbation bounds are obtained.

In this paper, a comprehensive algorithm is developed to analyze the sensitivity of hierarchical decision models (HDM), including the analytic hierarchy process and its variants, to single and multiple changes in the local contribution matrices at any level of the decision hierarchy. The algorithm is applicable to all HDM that use an additive function to derive the overall contribution vector. ...

Sampling-based methods for uncertainty and sensitivity analysis are reviewed. The following topics are considered: (i) definition of probability distributions to characterize epistemic uncertainty in analysis inputs, (ii) generation of samples from uncertain analysis inputs, (iii) propagation of sampled inputs through an analysis, (iv) presentation of uncertainty analysis results, and (v) deter...

the aim of this study was to evaluate the mediating role of difficulties in emotion regulation in the relationship between dysfunctional attitudes and anxiety sensitivity among students of the islamic azad university of hamadan. the research method was correlation. the statistical population of this study consisted of all the university students from among which 200 students (120 females, 80 ma...

This contribution is devoted to risk-sensitive and risk-neutral optimality in Markov decision chains. Since the traditional optimality criteria (e.g. discounted or average rewards) cannot reflect the variability-risk features of the problem, and using the mean variance selection rules that stem from the classical work of Markowitz present some technical difficulties, we are interested in expect...

New, simple, accurate, sensitive, economical, and reproducible UV-spectrophotometric method was developed and validated for the estimation of Lacidipine in bulk and tablet dosage form. Lacidipine shows maximum absorbance at 615.7 nm and linearity (Beer’s Lamberts law) was found to be in the range of 10-70 μg/ml. The apparent molar absorptivity and Sandell’s sensitivity coefficient were found to...

introduction: sperm viability test is important in diagnosis and treatment of male infertility. the common test is e&n; and host which they are based on membrane permeability and integrity. the aim of this study was to evaluate mtt assay as a sperm viability test based on mitochondrial activity. materials and methods: washed sperm samples were co-incubated with mtt in different media and differ...

BACKGROUND Historically, torso obesity has been difficult to quantify. Digital technology has recently encroached into body contouring surgery but has not been developed by surgeons to aid with their anatomical mandates. METHODS For 3 years, the authors tested a three-dimensional digital body camera that used nonintrusive white light phase profilometry to produce a "point cloud" image of the ...
