To accurately describe the mechanical properties of aluminium alloy sheet during deformation, an inverse identification was presented to deal with material parameters from the popular punch stretch test. In the identification procedure, the optimization strategy combines finite element method (FEM), Latin hypercube sampling (LHS), Kriging model and multi-island genetic algorithm (MIGA). The pro...
Abstract Both advanced high strength steels and aluminum alloys gained increasing popularity because of the constant effort to meet social pressure reducing vehicle weight while keeping their safety. The ratio between material is much higher when compared other materials but, springback after forming one disadvantages these materials, particularly exhibiting twisting side wall curl, which are t...
Soybean is the promising oilseed in the face of protein and oil shortage. In this study 16 advanced soybean genotypes, in terms of seed yield and yield components were evaluated using multivariate statistical methods. This experiment was carried out in the form of randomized complete block design (RCBD) in the research farm of Ardabil Agricultural and Natural Resources Research Center (Moghan...
The wide application of advanced high strength steels with specific in the automotive industry can significantly reduce energy consumption and contribute to carbon neutrality. Accurate prediction ductile fracture behavior under complex stress states is great significance for its automobile industry. In this study, QP980 states, covering shear, uniaxial tension, plane strain investigated by cond...
Recently larger numbers of women of advanced age are referring to fertility centers. Although there may be no age restriction for women who are naturally able to and want to be pregnant, using assisted reproductive techniques for women of advanced age is medically and ethically disputed, and this question is always raised: "Should there be an age limit for accessing assisted reproductive techni...
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
Recent work by Seltzer [1] indicates that classical approaches to beamforming, minimizing output power while enforcing a distortionless constraint, do not yield optimal results in terms of word error rate (WER) on speech recognition task. This problem can be traced back to the mismatch between the target criterion of classical adaptive beamformers, which is optimization of the signal to noise r...
A 2007 study by Regier, Kay, and Khetarpal purports to show that universal categories emerge as a result of optimal partitioning of color space. Regier, Kay, and Khetarpal only consider color categorizations of up to six categories. However, in most industrialized societies eleven color categories are observed. This paper shows that when applied to the case of eleven categories, Regier, Kay, an...
Three of the most important criteria for cryptographically strong Boolean functions are the balancedness, the nonlinearity and the propagation criterion. This paper studies systematic methods for constructing Boolean functions satisfying some or all of the three criteria. We show that concatenating, splitting, modifying and multiplying sequences can yield balanced Boolean functions with a very ...
