Exploratory factor analysis is commonly used in IS research to detect multivariate data structures. Frequently, the method is blindly applied without checking if the data at hand fulfill the requirements of the method. In this paper, we investigate the influence of sample size, data transformation, factor extraction method, rotation and number of factors on the outcome. We compare classical exp...

In this paper, we introduce a model-free algorithm, robust mode analysis (RMA), to extract primary constituents in fluid or reacting flow directly from high-frequency, high-resolution experimental data. It is expected be particularly useful studying strongly driven flows, where nonlinearities can induce chaotic and irregular dynamics. The lack of precise governing equations the absence symmetri...

In this paper, we propose formulations and algorithms for robust portfolio optimization under both aleatory uncertainty (i.e., natural variability) and epistemic uncertainty (i.e., imprecise probabilistic information) arising from interval data. Epistemic uncertainty is represented using two approaches: (1) moment bounding approach and (2) likelihood-based approach. This paper first proposes a ...

in order to study the correlation between morphophenological and quantitative traits with yield and to determine the most important traits for yield, 600 ecotypes of mung bean were evaluated in normal and limited irrigation conditions through augmented design. computation of correlation coefficients showed that in two conditions, number of pods per plant, harvest index and biological yield had ...

accurate permeability estimation has always been a concern in determining flow units, assigning appropriate capillary pressure andrelative permeability curves to reservoir rock types, geological modeling, and dynamic simulation.acoustic method can be used as analternative and effective tool for permeability determination. in this study, a four-step approach is proposed for permeability estimati...

The main contribution of the paper is to show the equivalence between the following two approaches for obtaining suucient conditions for the robust stability of systems with structured uncertainties: (i) apply the classical absolute stability theory with multipliers; (ii) use modern theory, speciically, the upper bound obtained by Fan, Tits and Doyle IEEE TAC, Vol. 36, 25-38]. In particular, th...
