Molecular Mechanicss. Classical MD simulations for larger molecules use empirical force fields, which approximate the potential energy surface of the electronic ground state. They are able to describe structural and conformational changes but not chemical reactions which usually involve more than one electronic state.

Supplier relationships to family firms,more stable method. The dimensionality of a data matrix can be reduced with the help of singular value decomposition, which allows to approximate a matrix by another matrix of lower rank and is also useful for linear regression, especially if the columns of the data matrix are linearly dependent.

Finite differences and finite volumes belong to the general class of finite element methods which are prominent in the engineering sciences and use an expansion in piecewise polynomials with small support. Spectral methods, on the other hand, expand the solution as a linear combinatio

This is utilized in a computer experiment to study the dependence of the polymer extension on an applied external force (this effect is known as entropic elasticity).
