RF ionization rates for mixtures of air with bariurn are computed using a Fokker-Planck code. It is shown that there is an optimum mixing ratio of barium to air, significantly ower than unity, which maximizes the ionization rate for a given value of incident RF power density and frequency. Rocket injection of barium at a selected height reduces ignificant/y the RF breakdown threshold for the mi...

Six Sigma is a strategy for achieving process improvement and operational excellence within an organization. Decisions on critical parameter selection in analysis phase are always very crucial; it plays a primary role in successful execution of Six Sigma project and for productivity improvement in manufacturing environment and involves the imprecise, vague and uncertain information. Using a cas...

In this paper we continue the investigation into the group of algebras with uniformly distributed invariants U(K), and its relation to the Schur subgroup, undertaken in [9]. The notation is the same as in [9]. In the first section we investigate the index 1 U(K), : S(K), 1 where q is an odd prime. We obtain [9, Theorem 2.71 as a special case of Theorem 1.2, wherein we obtain that the above inde...

The covariance matrix is formulated in the framework of a linear multivariate ARCH process with long memory, where the natural cross product structure of the covariance is generalized by adding two linear terms with their respective parameter. The residuals of the linear ARCH process are computed using historical data and the (inverse square root of the) covariance matrix. Simple measure of qua...

story has long been exploited to transfer human culture and concepts. it is the most consistent verbal form to the human mind. therefore, its audience spectrum is more widespread and its influence power is higher. though the qur'an's main language is the language of religion and spiritual guidance, it exploits the storytelling method in its complete form to disseminate its message.  u...
