Structure‐guided forcefield optimization [PDF]

Proteins: Structure, Function, and Bioinformatics, 2011
AbstractAccurate modeling of biomolecular systems requires accurate forcefields. Widely used molecular mechanics (MM) forcefields obtain parameters from experimental data and quantum chemistry calculations on small molecules but do not have a clear way to take advantage of the information in high‐resolution macromolecular structures.

Optimization of structural elements [PDF]

, 1976
A numerical method for the solution of structural optimization problems involving ordinary differential equations is presented for a simple situation where the constraint is of an aeroelastic nature. The method is adapted from optimal control theory and has proven successful in a number of structural optimization problems.

The Structure and Optimization of Speechreading [PDF]

Journal of Deaf Studies and Deaf Education, 1997
Erber (1988) has claimed that one of the reasons for the ascendancy of hearing aids has been the loss of confidence in speechreading. Speechreading can be of value to those suffering from presbyacusis and other hearing disorders, in augmenting hearing aids and cochlear implants, for large numbers of people in developing countries who are unable to ...
