The integration of various tools is a common requirement throughout the software development process. It is often desirable to consult several tools that perform similar functionalities in the same domain to obtain different perspectives and results to assist design and maintenance decisions. In many cases, tool interoperability requires the generalization of tool-specific data, which requires ...

During the last decade, software engineering researchers have tried to identify the success and obstacle factors to the software development. Conclusions from many of the researches related to the issue show that software process is one of the most important subjects contributing into the success or failure to the software development. Among the Capability Maturity Model Integration (CMMI), the...

objecitve: there have been contradictory findings on the relationship between socioeconomic status (ses) and child development although a wide range of results indicates that ses is associated with child development outcomes. the present study intended to define the relationship between ses and child development in tehran kindergartens. methods: this cross-sectional survey studied 1036 children...

In this study, a macro-economic model consisting of twelve behavioral equations and fourteen identity equations was estimated with the aim of investigating the effectiveness of monetary and fiscal policies set out in the fourth and fifth development plans. In the estimated model, the variables of development expenditures, current expenditures and tax revenues are used as fiscal policy tools and...

background: prognostic models have clinical appeal to aid therapeutic decision making. two main practical challenges in development of such models are assessment of validity of models and imputation of missing data. in this study, importance of imputation of missing data and application of bootstrap technique in development, simplification, and assessment of internal validity of a prognostic mo...

It is widely recognised that software development is a complex process. Among the factors that contribute to its inherent complexity is the gap between the design and the formal analysis domains. Software design is often considered a human oriented task while the analysis phase draws on formal representation and mathematical foundations. An example of this dichotomy is the use of UML for the so...

In this paper, we propose the technique to define the metrics of model transformation using a meta-modeling technique and a graph rewriting techniques in a Model Driven Development (MDD) context.
