OPLS all-atom force field for carbohydrates
Journal of Computational Chemistry, 1997The OPLS all-atom (AA) force field for organic and biomolecular systems has been expanded to include carbohydrates. Starting with reported nonbonded parameters of alcohols, ethers, and diols, torsional parameters were fit to reproduce results from ab initio calculations on the hexopyranoses, α,β-d-glucopyranose, α,β-d-mannopyranose, α,β-d ...

Optimization of the OPLS-AA Force Field for Long Hydrocarbons
Journal of Chemical Theory and Computation, 2012The all-atom optimized potentials for liquid simulations (OPLS-AA) force field is a popular force field for simulating biomolecules. However, the current OPLS parameters for hydrocarbons developed using short alkanes cannot reproduce the liquid properties of long alkanes in molecular dynamics simulations. Therefore, the extension of OPLS-AA to (phospho)

OPLS in batch monitoring – Opens up new opportunities
Analytica Chimica Acta, 2015In batch statistical process control (BSPC), data from a number of "good" batches are used to model the evolution (trajectory) of the process and they also define model control limits, against which new batches may be compared. The benchmark methods used in BSPC include partial least squares (PLS) and principal component analysis (PCA).

The OPL Access Control Policy Language
2009Existing policy languages suffer from a limited ability of directly and elegantly expressing high-level access control principles such as history-based separation of duty [22], binding of duty [26], context constraints [24], Chinese wall properties [10], and obligations [20].

World’s Highest Wind Turbine Generator, Ople, Germany
Structural Engineering International, 2001Wind turbine generators can be run most effectively in windy areas. On the coast, they can be economically viable at heights of 40 m to 70 m. In inland areas, however, wind speeds at such low levels are not usually sufficient for cost-effective operations.

The Modeling Language OPL — A Short Overview
2003OPL is a modeling language for mathematical programming and combinatorial optimization problems. It is the first modeling language to combine high-level algebraic and set notations from modeling languages with a rich constraint language and the ability to specify search procedures and strategies that is the essence of constraint programming.

OPL. Factors affecting OPL performance.
National network (Dallas, Tex.), 2002Case study. The CEO of a mid-size community hospital requested a literature search on the standards, costs and regional competition for a pain management center. Results submitted were deemed less than satisfactory. A review of the case suggests numerous elements, listed below, which need to be addressed and revised in order to improve outcome in ...

Die Arbeitssituation theologischer OPLs : eine empirische Untersuchung
2005In der Untersuchung wird einleitend ein Überblick über bereits erfolgte OPL-Befragungen gegeben sowie das Untersuchungsziel umrissen. Es werden die Leitsätze bzw. die Leitlinien der Evangelischen und Katholischen Kirche dazu einbezogen. Die Befragungsmethode, der Fragebogen und die Durchführung der Befragung werden vorgestellt.
