the present research is concerned with the determination of ductility, over-strength and response modification factors of coupled steel shear wall frames. three structural models with various numbers of stories, bay width and coupling beam height were analyzed using static pushover and incremental nonlinear dynamic analyses. the ductility, over-strength and response modification factors for the...
measurements of pb, cu, zn, as, ni, hg, and fe heavy metals and major elements and components such as ca, hco3, so4, na, k, mg and cl in soluble rain fractions were performed on rainwater collected at arak plain during the rainy seasons of 2012. concentrations of the heavy metals in the soluble fractions decreased for fe, pb, zn, ni, cu, as and hg, respectively and the major elements and compon...
Systematic spectral analysis of Phase Shifting Interferometry (PSI) algorithms was first proposed in 1990 by Freischlad and Koliopoulos (F&K). This analysis was proposed with the intention that "in a glance" the main properties of the PSI algorithms would be highlighted. However a major drawback of the F&K spectral analysis is that it changes when the PSI algorithm is rotated or its reference s...
Recently dietary pattern analysis has emerged as a way for examining diet-disease relations in Alzheimer's disease. In contrast with the conventional approach, which focuses on a single nutrient or a few nutrients or foods, this method considers overall eating patterns. We examined the dietary patterns defined by factor analysis using data collected with a food-frequency questionnaire in people...
We recently defined systematic modes of spatial and temporal variation in a 372-month record of streamflow using the principal components analysis (PCA). The unrotated and orthogonally rotated (varimax) components were previously calculated from a matrix of monthly streamflow records of 78 stations in Turkey for the period 1964-1994. As a result, the basic anomaly patterns by the unrotated comp...
This article proposes sparse and easy-to-interpret proximate factors to approximate statistical latent factors. Latent in a large-dimensional factor model can be estimated by principal component analysis (PCA), but are usually hard interpret. We obtain that easier interpret shrinking the PCA weights setting them zero except for largest absolute ones. show constructed with only 5%–10% of data su...
