Modi ed Nel and Van der Merwe test for the multivariate Behrens – Fisher problem

A new test to the multivariate Behrens–Fisher problem is obtained by modifying Nel and Van der Merwe’s (Comm. Statist. Theory Methods 15 (1986) 3719) test. The new test is a8ne invariant and it simpli es to the Welch’s approximate solution to the univariate case. The merits of the new test and two existing invariant tests are evaluated using Monte Carlo method. Monte Carlo comparison shows that...

Theoretical Considerations of Electrochemical Phase Formation in a Frank-van der Merwe System

Static calculation and preliminary kinetic Monte Carlo simulation studies are undertaken for the nucleation and growth on a model system which follows a Frank-van der Merwe mechanism. In the present case, we consider the deposition of Ag on Au(100) and Au(111) surfaces. The interactions were calculated using the embedded atom model. The process of formation and growth of 2D Ag structures on Au(...
