The creation of virtual reality applications and 3D environments is a complex task that requires good programming skills and expertise in computer graphics and many other disciplines. The complexity increases when we want to include complex entities such a ...
SystemC AMS extensions introduce new language constructs for the design of embedded analog/mixed-signal systems. This paper presents the novel modeling language for analog and mixed-signal functions that supports design and modeling of telecommunications, ...
Model Driven Engineering (MDE) promotes the use of models as primary artefacts of a software development process, as an attempt to handle complexity through abstraction, e.g. to cope with the evolution of execution platforms. MDE follows a stepwise approac ...
Functional Dependency has been extensively studied in database theory. It provides an elegant formalism for specifying key constraints and is the basis for normalization theory used in Relational database design. Given its known axiomatization through logi ...
Modern software is reaching levels of complexity encountered in biological systems; sometimes comprising systems of systems each of which may include tens of millions of lines of code. Model Driven Engineering (MDE) advocates raising the level of abstracti ...
The era of distributed systems is upon us. The Internet revolution, combined with the recent explosion of smart devices, indicate a clear trend toward ubiquitous and pervasive computing that will continue to change the way people live and interact, the way ...
Most of the efforts concerning graphical representations of humans (Virtual Humans) have been focused on synthesizing geometry for static or animated shapes. The next step is to consider a human body not only as a 3D shape, but as an active semantic entity ...
The subject of research in this paper is RM-ODP, an ISO/ITU-T international standard. We investigate an important challenge that the standard faces, specifically the absence of a satisfactory formalization of its proposed conceptual framework. We report on ...
UML State Machines constitute an integral part of software behavior specification within the Unified Modeling Language (UML). The development of realistic software applications often results in complex and distributed models. Hence, potential errors can be ...
The syntax of modeling languages is usually defined in two steps. The abstract syntax identifies modeling concepts whereas the concrete syntax clarifies how these modeling concepts are rendered by visual and/or textual elements. While the abstract syntax i ...
