The presence of wall strengtheners in double-stage electrostatic precipitators affects gas velocity, electrical field and particle movement over the ESP. In this work we have used our previous mathematical model for double-stage ESP {Talaie et. al (2001) [10]] to study the effect of wall strengtheners on the performance of double-stage ESP. One of the important findings was that, due to the fac...

Brualdi et al. introduced the concept of poset codes, and gave an example of poset structure which admits the extended binary Hamming code to be a double-error-correcting perfect P-code. Our study is motivated by this example. In this paper we classify all poset structures which admit the extended binary Hamming code to be a double or triple-error-correcting perfect P-code. © 2004 Elsevier B.V....

radioiodinated meta iodobenzylguanidine (mibg) is one of the important radiopharmaceuticals in nuclear medicine. [123/131i]mibg is used for imaging of adrenal medulla, studying heart sympathetic nerves, treatment of pheochromacytoma and neuroblastoma. for clinical application, radioiodinated mibg is prepared through isotopic exchange method, which includes replacement of radioactive iodine in a...

in 2004, rodr'{i}guez-lallena and '{u}beda-flores have introduced a class of bivariate copulas which generalizes some known families such as the farlie-gumbel-morgenstern distributions. in 2006, dolati and '{u}beda-flores presented multivariate generalizations of this class. then in 2011, kim et al. generalized rodr'{i}guez-lallena and '{u}beda-flores' study to any...

Detailed study of Lindley distribution (1.3) has been done by Ghitany et al. [4] and shown that (1.3) is a better model than exponential distribution for modeling some lifetime data. Recently, Shanker et al. [5] showed that (1.3) is not always a better model than the exponential distribution for modeling lifetime’s data. In fact, Shanker et al. [5] has done a very extensive and comparative stud...

abstract various mathematical water uptake models have been introduced for plants response to combined drought and salinity stress. the reduction functions are classified as additive, multiplicative and conceptual models. in this study six different macroscopic reduction functions, namely; van genuchten (additive and multiplicative), dirksen et al., van dam et al, skaggs et al and homaee were e...

Blackbody levels of emission in the electron cyclotron range of frequencies have been observed from an overdense (vpe;3vce) Madison Symmetric Torus @Dexter et al., Fusion Technol. 19, 131 ~1991!# reversed field pinch plasma, a result of electrostatic electron Bernstein waves emitted from the core and mode converted into electromagnetic waves at the extreme plasma edge. Comparison of the measure...
