Based on the trialism of science, technology and engineering, its category and way of thinking of systems engineering is introspected. And the necessity and feasibility of establishing the results-oriented systems engineering (abbr. ROSE), which belongs to the engineering category, is put forward. The new being which ROSE creates is in the form of system, and the process is of elements-integrating...

Because of unsatisfied efficiency and effect of the current on-line auto-generating paper, an algorithm of auto-generating paper based on KP (Knapsack Problem) was presented and the conventional method of solving KP was improved, that is, paper was separated into small packs according to itempsilas type and its difficulty and solved respectively by process of the solution to KP. The experiments show...
Description logics (short for DLs) are very important for the expression of ontologies, which allow reasoning about individuals and concepts. However, DLs can not process the indefinite knowledge existing widely in nature. Based on the cloud model, we present cloud-ALC to deal with the indefinite knowledge, which is the extension of the important description logic ALC. We define its syntax and semantic,...
