a new algorithm is proposed for calculations of distributed molecular polarizabilities. In contrast to published algorithms, it virtually eliminates the charge-flow terms that result in a slower than inverse sixth power decay of dispersion energy whereas the remaining terms have unique and physically reasonable values. Dispersion energies computed from these polarizabilities are very close to unexpanded dispersion energies in the region of small charge overlap. The method is expected to provide reference data for development of dispersion functions used in simulations of biomolecules and in dispersion-supplemented density-functional approaches.

The inverse problem of determining the time-varying strength of a heat source, which causes natural convection in a two-dimensional cavity, is considered. The Boussinesq equation is used to model the natural convection induced by the heat source. The inverse natural convection problem is solved through the minimization of a performance function utilizing the conjugate gradient method. The gradient of the performance function needed in the minimization procedure of the conjugate gradient method is obtained by employing either the adjoint variable method or the direct differentiation method. The accuracy and efficiency of these two methods are compared, and a new method is suggested that exploits the advantageous aspects of both methods while avoiding the shortcomings of: them.
