Current procedures for estimating the peaks of the stochastic response of tall buildings to wind are based on the assumption that the response is Gaussian. Those procedures are therefore inapplicable to low-rise buildings, in which time histories of wind-induced internal forces are generally non-Gaussian. In this paper, an automated procedure is developed for obtaining from such time histories ...

A copula is a useful tool for constructing bivariate and/or multivariate distributions. In this article, we consider a new modified class of FGM (Farlie–Gumbel–Morgenstern) bivariate copula for constructing several different bivariate Kumaraswamy type copulas and discuss their structural properties, including dependence structures. It is established that construction of bivariate distributions ...

The effect of four different levels of irrigation periods, including normal irrigation, irrigation after 100, 150, and 200mm evaporation, with three different bio-fertilizer including control, Mycorrhiza, and Rhizobium were investigated on morphological and yield traits of guar. The experiment was conduct in form of split-plot design with irrigation periods as main plots and bio-fertilizers as ...

The specific rates of solvolysis of propargyl chloroformate (1) are analyzed in 22 solvents of widely varying nucleophilicity and ionizing power values at 25.0 °C using the extended Grunwald-Winstein equation. Sensitivities to solvent nucleophilicity (l) of 1.37 and to solvent ionizing power (m) of 0.47 suggest a bimolecular process with the formation of a tetrahedral intermediate. A plot of th...

A rapid, simple, and sensitive method for quantitation of ethchlorvynol by gas Chromatography has been developed. instrument response is linear to a concentration of 200 mg/liter (2.0-mi sample of serum). Day-to-day (20 days) precision of a 15 mg/liter serum pool was 0.85 mg/liter (SD) and 5.6% (CV). For 30 samples analyzed by both the gas chromatographic method and a colorimetric method, the c...

The problem of evaluating a military or GPS/GSM system’s precision quality is considered in this article, where one sequentially observes bivariate normal data (Xi, Yi)’s andwants to test hypotheses on the circular error probability (CEP) or the probability of nonconforming, i.e., the probabilities of the system hitting or missing a pre-specified disk target. In such a problem, we first conside...

criteria in household portfolio. to do this, the data which are related to the asset price are used including: bank deposit, bonds, stock, exchange, coin, land and housing in time period of 1997 to 2011. in this research, portfolio var id calculated in the confidence level of 90%, 95%, and 99% and in time periods of one year and 14 years. after calculating returns, return standard deviation, co...

Speech is the fundamental way of communicating with one another. It simply refers to transmission of messages. In case of speech production the information is transmitted in the form of analog waveform that can be transmitted, recorded or decoded. A number of algorithms for speech recognition have been proposed. In this paper, we have suggested an innovative approach of speech recognition. We h...

OBJECTIVE To present the process of transcultural adaptation of the Richmond Compulsive Buying Scale to Brazilian Portuguese. METHODS For the semantic adaptation step, the scale was translated to Portuguese and then back-translated to English by two professional translators and one psychologist, without any communication between them. The scale was then applied to 20 participants from the gen...
