Conceptual modeling of XML data was made easier with the introduction of the XSEM model, which utilizes the MDA (Modeldriven architecture) ideas of multi-level modeling. XCase is an implementation of this model, enabling users to model their problem domain as a Platform-independent model (PIM), from which Platform-specific models (PSM), XML schemas in our case, can be derived. The main advantag...

In this position paper we present a framework for the modeling and enforcement of usage control-based privacy policies. In this work we introduce only PIM (Platform Independent Model) meta-models and briefly sketch how they can be transformed into the meta-models of PSM (Platform Specific Model) and finally generate the security architecture.

This paper formulates a set of minimal requirements for the Platform Independent Model (PIM) of the Model Driven Architecture (MDA). It then defines the Use Case, Responsibility Driven Analysis and Design methodology (URDAD) which provides a simple, algorithmic design methodology generating a PIM satisfying the specified PIM requirements. 2008 Elsevier B.V.

An accurate calibration of inertial measurement unit errors is increasingly important as the inertial navigation system requirements become more stringent. Developing calibration methods that use as less as possible of IMU signals has 6-DOF gimballed IMU in space-stabilized mode is presented. It is considered as held stationary in the test location incorporating 15 di...

E-applications are increasingly being composed from individual services that can be realized with different technologies, such as, e.g., Web Services and standard component technologies. A current trend in the development of these services is to describe their technology-independent and technology-specific aspects in separate models. A prominent development that leads this trend is the Model-Dr...

The Model Driven Architecture (MDA) maintains that systems can be abstractly specified, and specifically instantiated. The abstract specification is created using formally defined models; thus in order to fulfill these ambitions, model transformations must be employed on some level. The definition of these transforms—however—is not a trivial task. In addition to the basic problems of the transf...

Diverse development web methodologies currently exist in the field of Model-Driven Web Engineering (MDWE), each of which covers different Levels of Abstraction on Model-Driven Architecture (MDA): Computation Independent Model (CIM), Platform Independent Model (PIM), Platform Specific Model (PSM), and Code. Given the high number of methodologies available, it has become necessary to define objec...

Only in software and in linguistics a model has the same nature as the thing it models. In software at least, this opens the possibility to automatically derive software from its model. This property is well known from any compiler writer (and others), but it was recently be made quite popular with an OMG initiative called the Model Driven Architecture (MDA). The model transformations allowing ...

Wave run-up is one of the most important and effective parameters in designing semi-submersible platforms. Besides unforeseen effects on the movements and response of the platform, wave run up can also cause slamming forces to be exerted on the lower deck of the platform. Therefore, at the first stages of this plan, before running tests on the model of the platform, numerical methods are usuall...
