Reusing ontologies for new purposes, or adapting them to use-cases, is frequently difficult. In our experiences, we have found this be the case several reasons: (i) differing representational granularity in and (ii) lacking conceptual clarity potentially reusable ontologies, (iii) lack difficulty of adherence good modeling principles, (iv) a reuse emphasis process support available ontology eng...

a modular $k$-coloring, $kge 2,$ of a graph $g$ without isolated vertices is a coloring of the vertices of $g$ with the elements in $mathbb{z}_k$ having the property that for every two adjacent vertices of $g,$ the sums of the colors of the neighbors are different in $mathbb{z}_k.$ the minimum $k$ for which $g$ has a modular $k-$coloring is the modular chromatic number of $g.$ except for some s...

This article discusses a new modular design approach for hybrid models consisting of a dynamic framework augmented with static fuzzy sub-models. As the framework is physically based, the models have a dynamic behaviour that corresponds well with the original process. Their fit to process data assures good steady state behaviour and corrects the dynamic behaviour for assumptions and simplificati...

The use of subprocesses in large process models is an important step in modeling practice to handle complexity. While there are several advantages attributed to such a modular design, including ease of reuse, scalability, and enhanced understanding, the lack of precise guidelines turns out to be a major impediment for applying modularity in a systematic way. In this paper we approach this area ...

The DEVS formalism supports modeling of discrete event systems in a hierarchical, modular manner based on the object-oriented world view. System modeling requires not only understanding of modeling framework but also domain kno-wledge of the system. Therefore, successful modeling may need a means to represent a system which is understandable to both domain experts and M&S experts. This paper pr...

This paper introduces the theoretical design of reconfigurable machine tools using modular design approach. First, the general concept of modular robot and its growing need is introduced. Second, the design of reconfigurable parallel kinematic machines is discussed and the geometric modeling of such figures is presented and explained, and potential applications are described. Finally, a case st...
