Solar energy potential calculation methods
RE&PQJSeveral European municipalities developed an information map called solar cadaster that provide qualitative information for the citizens about the possible locations and amount of the small scale household solar PV system installations. The objective of these cadasters is the promotion and fostering of the distribution of the PV systems.

Energy levels of the laser-dressed Coulomb potential by the potential envelope method
Journal of Physics B: Atomic, Molecular and Optical Physics, 1994The method of potential envelopes is employed to approximate the bound-state energies of the Schrodinger Hamiltonian, - Delta - upsilon /(r2+ lambda 2)12/. It is shown that the simple formula E=minr>0(P2/r2- upsilon /(r2+ lambda 2)12/) provides upper bounds to the energies if P=(2n+l-1/2) and lower bounds when P=(n+l), with accurate values found by ...

Modelling of potential energy curves for diatomics: Reference molecular potential method
Chemical Physics Letters, 1985A method is suggested for modelling the potential energy curves of diatomics. It involves a search for the mapping which transfers the structural details from an analytically prescribed reference potential. For the ground-state potentials of seven covalent molecules, the accuracy in describing the spectroscopic region is comparable with the best ...

Methods for Calculating Intermolecular Potential Energy Surfaces
1991It is now possible to carry out accurate ab initio calculations on hydrogen-bonded complexes by a variety of techniques. The supermolecule approach is widely used, and is capable of high absolute accuracy, but it is subject to Basis Set Superposition Error, especially when electron correlation is taken into account, and this is a difficulty when ...

Ensemble method to measure the potential energy of nanoparticles in an optical trap
Optics Letters, 2011A method is described for measuring the potential energy of nanoparticles in an optical trap by trapping an ensemble of particles with a focused laser beam. The force balance between repulsive osmotic and confining gradient-force pressures determines the single-particle trapping potential independent of interactions between the particles.

Generalized scaling variational method and energy eigenvalues for the Yukawa potential
Physical Review A, 1985In a previous paper [Phys. Rev. A 30, 1229 (1984)] we applied the scaling variational method formulated in terms of the SO(2,1) dynamical group to screened Coulomb potentials. Here we generalize that method by scaling a linear combination of SO(2,1) basis states, solving for the eigenvalues by determinant, and minimizing through a search algorithm. The

Methods for finding transition states on reduced potential energy surfaces
The Journal of Chemical Physics, 2010Three new algorithms are presented for determining transition state (TS) structures on the reduced potential energy surface, that is, for problems in which a few important degrees of freedom can be isolated. All three methods use constrained optimization to rapidly find the TS without an initial Hessian evaluation.

Energy dependence of the ion-ion potential with a simplified energy density method
Nuclear Physics A, 1978Abstract A general form of the ion-ion potential is obtained using the energy density method along the lines by Ngo et al ., but with a very simple form of the energy density introduced by Skyrme. The results are in good agreement with the ones of Blocki et al .

Practical hyperdynamics method for systems with large changes in potential energy
The Journal of Chemical Physics, 2014A practical hyperdynamics method is proposed to accelerate systems with highly endothermic and exothermic reactions such as hydrocarbon pyrolysis and oxidation reactions. In this method, referred to as the “adaptive hyperdynamics (AHD) method,” the bias potential parameters are adaptively updated according to the change in potential energy.
