This paper proposes an algorithm for image processing, obtained by adapting to image maps the definitions of two well-known physical quantities. These quantities are the dipole and quadrupole moments of a charge distribution. We will see how it is possible to define dipole and quadrupole moments for the gray-tone maps and apply them in the development of algorithms for edge detection. 1. Introd...

Theoretically predictionq of the solvent effects of I - pentadecanoyl - 2 -docosahexaennyl - Sn - glycerol3 - phosphocholin have been studied using 'Jamey-lock quantiun chemical approximation and STD - 30basis set within the Onsager Self-Consistent Reaction field (SCRS') model All optimized conformers of I -pentadecanoyl - 2 -docosahexaenoyI - Sn - glycerol 3 - phosphocholin as well as their to...

Anions that exhibit dipole-bound singlet states have been proposed as a potential class of molecules that may be identified in the interstellar medium. Using high-level coupled cluster theory, we have computed the dipole moments, electron binding energies, and excited states of 14 neutral radicals and their corresponding closed-shell anions. We have calibrated our methods against experimental d...

Rydberg atoms with large electric dipole moments, strong dipole–dipole interactions, and long radiative lifetimes have attracted great attention become the subject of intense studies in past two decades [...]

The relativistic configuration interaction valence-bond method has been used to calculate permanent and transition electric dipole moments of the KRb heteronuclear molecule as a function of internuclear separation. The permanent dipole moment of the ground-state X S potential is found to be 0.30~2! ea0 at the equilibrium internuclear separation with excess negative charge on the potassium atom....

Recent papers that have studied variants of the Peyrard-Bishop model for DNA, have taken into account the long range interaction due to the dipole moments of the hydrogen bonds between base pairs. In these models the helicity of the double strand is not considered. In this paper we have performed an analysis of the influence of the helicity on the properties of static and moving breathers in a ...

The dipole-dipole interaction influences nanoscopic matter by fixing the patterns of permanent, displacive, and induced dipole moments, subject to constraints of molecular size and other short range interactions. Prediction of these arrangements is a challenging problem. The eigenvector of maximum eigenvalue of the dipole-dipole interaction matrix can provide insights and sometimes a complete s...

From the famous experiments of Stern and Gerlach to the present, measurements of magnetic dipole moments, and searches for electric dipole moments of “elementary” particles have played a major role in our understanding of sub-atomic physics. In this talk I discuss the progress on measurements and theory of the magnetic dipole moment of the muon. I also discuss a new proposal to search for a per...

We consider a dilute gas of dipole moments in an arbitrary harmonic trap and treat both the short-range, isotropic interaction and the long-range, anisotropic dipole-dipole interaction perturbatively. In this way, we calculate the leading shift of the critical temperature with respect to that of an ideal gas as a function of the relative orientation of the dipole moments with respect to the har...
