Modern, complex control systems for a specific application domain often display common system design architectures with similar subsystem functionality and interactions, making them suitable for representation by a reusable specification architecture. For example, every spacecraft requires attitude determination and control, power, thermal, communications, and propulsion subsystems. The similar...

Nowadays, model checking is recognized as an efficient technology for verifying system properties. There are many tools such as SPIN and NuSMV supports model checking that will greatly enhance software systems applicability. However, it is difficult to establish a tool to directly verify Object-Z, because of its highlevel abstraction. This paper puts the Object-Z specification into label transi...

This article deals with the dialog specification for interactive applications. Most of existing models are based on transition diagrams, but they give too attention to implementation considerations. Therefore, we reconunend a new model completely independent of any implcmentation problem. The dialog is broken down into a serics of queries, responses, results. This generic model is the main tool...

This paper studies the design of specification languages through their model theory. We show how language constructs and specification idioms are deeply rooted in the underlying model theory. We also show that some problems are fundamentally difficult to specify due to the underlying foundation of the language. The languages we study are Alloy, Maude, and FORMULA. FORMULA attempts to handle a l...

In this paper we present a domain specific language (DSL) for Extended Entity-Relationship (EER) data model approach, named EERDSL. EERDSL is a part of our Multi-Paradigm Information System Modeling Tool (MIST) that provides EER database schema specification at the conceptual level and its transformation into a relational data model, or a class model. EERDSL modeling concepts are specified by E...

Model transformations are a central element of model-driven development (MDD) approaches. The correctness, modularity and flexibility of model transformations is critical to their effective use in practical software development. In this paper we describe an approach for the automated derivation of correct-by-construction transformation implementations from high-level specifications. We illustra...

A Model for the Specification of Abstract User Interfaces based on Conceptual Patterns is proposed to enhance the semantic captured by an object-oriented analysis method. The model gathers both Presentation an Navigation issues. A graphical notation is also provided to make easier the specification tasks. This simple graphical notation allows that a non analyst can understand and participate in...

In Model-Driven Engineering, a software development process is a sequence of manipulation tasks that are applied to models, where model transformations play a relevant role. MOMENT (MOdel manageMENT) is a framework that is integrated in the Eclipse platform. MOMENT provides a collection of generic set-oriented operators to manipulate EMF models. In this paper, we present the model transformatio...

The coefficient of prediction 2 j P is derived from the PRESS (prediction sum of squares) statistic just as 2 j R is derived from SSE, the error sum of squares. While 2 j R measures quality of fit, 2 j P measures quality of point predictions. Unlike SSE and PRESS, 2 j R and 2 j P are bounded, relative measures ideally suited for statistical modeling. This paper describes the limits, properties,...

Model checking has received wide acceptance as a valuable technique in the field of electronic design automation and is currently of growing interest in general systems design. Though its concepts and applications are well understood it often turns out that engineers have severe problems with the specification process and the underlying notation, i.e., formulation and understanding of specifica...
