Evolving Paradigms and Models in Multi-Paradigm Modeling
نویسندگان
چکیده
The essence of model based software development for domain specific applications is in the definition of a meta-model that captures the key aspects of the domain. However, the meta-model rarely defines the domain completely, and must often be modified to reflect our improved understanding of the domain during the course of development and subsequent use of domain specific software. The modification of the meta-model creates a versioning problem, whereby existing models may no longer conform to the modified meta-model. This report describes the Universal Model Migrator, a tool that allows domain designers to declaratively specify incremental modifications to their meta-models, in order to facilitate the automatic evolution of domain models to remain conformant to the latest version of the meta-model.

متن کاملEvaluation of the Humanity Research Paradigms based on Analysis of Human – Environment Interaction
As claimed by many behavioral scientists, designing should be based on the knowledge of interaction between human and environment. Environmental quality is also created in the context in which humans interact with their environment. To achieve such quality, designers should develop appropriate models for explaining this relationship, and this requires an understanding of human nature and the en...

Physics-based modeling of sound sources, such as of musical instruments and speech production, is based on several different modeling paradigms or methodologies. These can be roughly categorized as finite difference schemes, mass-spring models, modal decomposition methods, digital waveguide models, wave digital filter models, and source-filter models. The three first methods are based on the us...
