for the polynomial planar vector fields with a hyperbolic or nilpotent critical point at the origin, the monodromy problem has been solved, but for the strongly degenerate critical points this problem is still open. when the critical point is monodromic, the stability problem or the center- focus problem is an open problem too. in this paper we will consider the polynomial planar vector fields ...

sea surface topography (sst) by definition is the separation between the geoid and the mean sea level (msl). the separation between the geoid and msl is caused by various non-gravitational physical effects. if determination of the geoid as the zero point of the height systems from the tide gauge observation be the goal, it is necessary that the affect of the physical effect be precisely compute...

the quantitative structure–property relationship (qspr) method is used to develop the correlation between structures of crude oil hydrocarbons (80 compounds) and their boiling point and water solubility. sub-structural molecular fragments (smf) calculated from structure alone were used to represent molecular structures. a subset of the calculated fragments selected using stepwise regression (fo...
