Flow induced by non-coaxial rotations of porous disk and a fluid in a porous medium

  This paper deals with the flow of an incompressible, viscous and electrically conducting fluid in a porous medium when no slip condition is no longer valid. The fluid is bounded by a non-conducting porous disk. The flow is due to non-coaxial rotations of porous disk and a fluid at infinity. The fluid is electrically conducting in the presence of a constant applied magnetic field in the transverse direction....

A study on a novel method of mining fuzzy association using fuzzy correlation analysis

  Two different data variables may behave very similarly. Correlation is the problem of determining how much alike the two variables actually are and association rules are used just to show the relationships between data items. Mining fuzzy association rules is the job of finding the fuzzy item-sets which frequently occur together in large fuzzy data set, where the presence of one fuzzy item-set in a record...

A sampling plan with producer’s allowable risk (PAR) at maximum allowable proportion defective (MAPD)

  This paper deals with sampling designs on incoming quality MAPD along with a specified probability of acceptance at this point called producer’s allowable risk (PAR). It is defined as the minimum probability of acceptance of the lot with a maximum allowable proportion defective. Tables and graphs are presented, comparing the efficiency of new SSP as to protect AQL. An optimum criterion of sample size...
