SAAS

The resulting similarity measures are overlap-like Sa b = J Pxi ) / B(r) Coulomblike, etc. The Carbo similarity coefficient is obtained after geometric-mean normalization Sa,b/ /Sa,a Sb,b (cosine), while the Hodgkin-Richards similarity coefficient uses arithmetic-mean normalization Sa,b/0-5 (Saa+ b b) (Dice). The Cioslowski [18] similarity measure NOEL - Number of Overlapping Electrons (Eq. (10)) - uses reduced first-order density matrices (one-matrices) rather than density functions to characterize A and B. No normalization is necessary, since NOEL has a direct interpretation, at the Hartree-Fodt level of theory.

Certified testing and approval for control-valve devices used in hazardous locations is normally procured by the manufacturer of the device. The manufacturer often goes to a third party laboratory for testing and certification. Applicable approval standards are available from CSA, CENELEC, EM, SAA, and UL.

Saa = -esB = e was chosen, and an effective coordination number Zcir = 2.5 occurred ) Thus one finds that the coefficient in the relation T N ,r is somewhat smaller than expected from Eq. (3), and in addition there is a "chain end"-correction. However, an integral equation theoryyielded Tc cc Vn, and th simulations showed that this result clearly is incorrect. More recent improved versions of integral equation theories now yield Tc N as well but still the theoretical understanding of the prefactor in this relation is limited.
