Abstract: It has been found that the balance between friction reduction in the engine crankcase and the maintenance of sufficient friction in the clutch assembly of a 4T motorcycle, where the engine crankcase and the clutch assembly are lubricating by the same lubricating oil composition from a common sump, can be achieved by use of a lubricating oil composition comprising a combination of molybdenum containing additive and ashless organic friction modifier.

Abstract: The present invention provides an expert system for suggesting and providing graphic design selections based on a user's desired result. The invention provides a plurality of descriptors to define the characteristics of an output page or document. A user can "scale" or "weight" the descriptors, as desired. The present invention utilizes the weighted descriptors to select a number of solutions from a predefined database of possible solutions. The "fit" of each database solution to the user criteria is determined via an intelligent search. Initially, solutions that do not satisfy rejection constraints are identified and eliminated. These rejection constraints are binary constraints and may be the result of output device limitation, intended audience, environment of use, availability of color, etc. The elimination of solutions that do not meet the rejection constraints reduces the population of possible solutions, simplifying further researches and analysis.
