Forest chips for energy in Europe: Current procurement methods and potentials
Renewable and Sustainable Energy Reviews, 2013Abstract Forest chips are becoming an important alternative resource for energy in Europe. The aim of this study is to review and analyze the current procurement methods and potentials of forest chips in Europe, based on questionnaires sent to relevant experts in different countries as well as a literature review of existing literature.

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

A method for assessing the market potential of new energy-saving technologies
IEEE Transactions on Systems, Man, and Cybernetics, 1983An approach for estimating the market potential of new energy saving technologies is presented. The approach is based on the assumption that consumers implicitly minimize total expected lifetime costs when purchasing new technology. The techniques developed allow simultaneous comparison of any number of competing technologies.

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.

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 ...

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.

Calculation of free-energy differences and potentials of mean force by a multi-energy gap method
The Journal of Chemical Physics, 2008A method is proposed to significantly accelerate the convergence of free-energy calculations. It introduces a bias factor in Monte Carlo simulations or, equivalently, a bias force in molecular dynamics simulations. The bias factor targets the energy gap, i.e., the difference in energy function between two states, and is therefore specifically designed ...
