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...

We propose a criterion to determine a more appropriate software reliability growth model in the early development phase. The criterion with a discrete software reliability growth model determines the absolute worth of a model because the discrete software reliability growth model perfectly reproduces the parameter estimates when the data are used as an exact solution of the equation. The values...

the aim of the present study was to estimate genetic and phenotypic parameters of milk production traits in the first and second lactations of romanian simmental dairy cattle. for the estimation of variance, heritability, genetic and phenotypic correlations among milk yield, fat yield, protein yield, and percentages of fat and protein, 3400 first and second lactation records over a period of fi...

line g-14088 was first introduce in iran together with 60 other chitti bean lines in 1988 through ciat. it was tested in different breeding experiments for yield and agronomic characteristics and was compared with local cultivar checks and other advanced lines of chiti bean from 1988 to 2005 in different locations of iran. due to higher seed yield and favorable characteristics, it was selected ...

In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semi-analytical elastic-plastic solution using Tresca yield criterion alongwith deformation theory in plasticity with considernig the perfectly plastic behaviour of materials is presented. Simplifying the presented soluti...

A micromechanical damage constitutive model is presented to predict the overall elastoplastic behavior and damage evolution in random carbon fiber polymer matrix composites (RFPCs). To estimate the overall elastoplastic damage responses, an effective yield criterion is derived based on the ensemble-volume averaging process and first-order effects of eigenstrains due to the existence of spheroid...

spring back is responsible for inaccuracy of press formed sheet product. therefore, prediction of spring back is important for precise forming of stampings. to predict the amount of spring back many successful attempts have been made for simple cases such as single curved and u or v shape sheet metals. however, for more complex shapes containing double curves or double variable curved surfaces ...
