Business rules are statements that express (certain parts of) a business policy, defining business terms and defining or constraining the operations of an enterprise, in a declarative manner. Since these rules define and constrain the interaction among business agents in the course of business processes, they have to refer to the components of their mental state, such as the knowledge/informati...

Nonnegative Matrix Factorization (NMF) algorithms have been utilized in a wide range of real applications. NMF is done by several researchers to its part based representation property especially in the facial expression recognition problem. It decomposes a face image into its essential parts (e.g. nose, lips, etc.) but in all previous attempts, it is neglected that all features achieved by NMF ...

defining maturity level is one of the important elements of the excellence models. this approach helps companies to assess competitive positions and help them to benchmark from best practices. one of the significant features of excellence models is defining maturity level using subjective and conventional approach. present research is a cross-sectional study among iranian petrochemical companie...

Distributed information systems (DISs) are increasing in usage rapidly. But the software development life cycle for DISs has changed very little. In such a cycle, a modeling tool is used in the analysis and design phase to help developers to build UML analysis and design models; and then in the implementation and testing phase, an IDE (Iterative Development Environment) is used for textual prog...

The paper describes an approach for defining of k-best night vision devices based on multi-criteria mixed-integer optimization modeling. The parameters of night vision devices are considered as criteria that have to be optimized. Using different user preferences for the relative importance between parameters different choice of k-best devices can be defined. An ideal device with all of its para...

Multi-level modeling aims to reduce redundancy in data models by defining properties at the right abstraction level and inheriting them to more specific levels. We revisit one of the earliest such approaches, Telos, and investigate what needs to be added to its axioms to get a true multi-level modeling language. Unlike previous approaches, we define levels not with numeric potencies but with hi...

Model verification is the process of checking models for known problems (or anti-patterns). We propose a new approach to declaratively specify and automatically detect problems in domain-specific models using QVT (Query/View/Transformation). Problems are specified with QVT-Relations transformations from models where elements involved in problems are identified, to result models where problem oc...
