A NEW APPROACH TO THE ESTIMATION OF THE DISPERSION COMPONENTS
DISPERSION COMPONENTS unknown X iterative algorihm
font style='font-size:12px;'>
2009/3/31
A new method to calculate simultaneosly both the unknown X
and the components of the dispersion (results of measurement) is developed. An
improved iterative algorihm is used.

2010/4/16
Two sets of additive parameters used previously for the calculation of C-13 chemical shifts of mono and poly six-membered cycloalkanes were applied for the prediction of N-15 chemical shifts of some m...
A New Approach on Constant Angle Surfaces in E3
Constant angle surfaces Euclidean space
font style='font-size:12px;'>
2010/2/25
In this paper we study constant angle surfaces in Euclidean 3--space. Even that the result is a consequence of some classical results involving the Gauss map (of the surface), we give another approach...
