One of the main reasons for the success of Web 2.0 is the improvement in user experience. This improvement is a consequence of the evolution from HTML User Interfaces (UI) to more usable and richer UI. The most popular Web 2.0 applications have selected the Rich Internet Application (RIA) paradigm to achieve this goal. However, the current Web Engineering methods do not provide the expressivity...

We present an approach to the definition of an object-oriented modeling paradigm done in the scope of general system modeling. The paradigm includes a formally defined metamodel and its supporting philosophical and natural science foundations. The metamodel exhibits its internal consistency, supported by Russell’s theory of types, and its consistency in interpretation of subjects of modeling, s...

In order to integrate requirements into the current Model-Driven Engineering (MDE) approach, the traditional document-based requirements specification process should be changed into a requirements modelling process. To achieve this we propose a requirements metamodel called REMM (Requirements Engineering MetaModel) which includes the elements that should appear in a requirements model (requirem...

It is well known that metamodel or surrogate modeling techniques have been widely applied in engineering problems due to their higher efficiency. However, with the increase of the linearity and dimensions, it is difficult for the present popular metamodeling techniques to construct reliable metamodel and apply to more and more complicated high dimensional problems. Recently, neural networks (NN...

DQ metadata can be stored in a Metadata Repository (MDR). The structure of the MDR should be carefully defined to ensure a maximum amount of flexibility, generality and ease of use. It should also implement the major aspects of DQ management that are represented in the architecture of DQ. The basic DQ Metamodel should first provide representation of information products and data objects. It sho...

Like other software artefacts, metamodels evolve over time. We propose a transformational approach to assist metamodel evolution by stepwise adaptation. In the first part of the paper, we adopt ideas from grammar engineering to define several semanticsand instancepreservation properties in terms of metamodel relations. This part is not restricted to any metamodel formalism. In the second part, ...

Conceptual modelling is one of the core disciplines within business informatics. Often, different metamodels have to be integrated to provide project specific or domain specific modelling solutions. This is a challenging task due to the heterogeneity of the modelling languages being assembled. This paper presents an approach for integrating heterogeneous modelling languages in the domain of ent...

An important prerequisite for the generation of realistic material behavior with Discrete Element Method (DEM) is correct determination material-specific simulation parameters. Usually, this done in a process called calibration. One main disadvantage classical calibration fact that it non-learning approach. This means knowledge about functional relationship between parameters and responses does...
