Ubiquitous technologies, infrastructures, applications and services that operate across physical environments (e.g. neighbourhood, home, car etc) will soon be spanning all the different spheres of everyday life. Ubiquitous computing places humans in the ...

Publishing information in a virtual organization (VO) has become too easy due to low barriers; hence development of novel mechanisms to assess the quality of collected information has become a necessity. An evaluator makes such an assessment based on ...

A notion of symmetry for event structures is defined, which are based on permutation groups. Given an event structure and a permutation group over it, we introduce the quotient model of the event structure and show that the quotient model is trace, ...

In this paper, we propose to model and analyze applications with domain-specific languages by reflection. We argue that both tasks can be significantly simplified by using a reflective modeling language. To make our arguments, we model and analyze a ...

During the construction of a software metric model, the decision on whether a particular predictor metric should be included is most likely based on an intuitive or experience based assumption that the predictor metric has an impact on the target metric ...

It has been recently shown that computation with stochastic numbers as regard to addition and multiplication by scalars can be reduced to computation in familiar vector spaces. This result allows us to solve certain practical problems with stochastic ...

Many numerical computations, be they solutions to systems of differential equations or optimization problems coming from applied areas like protein folding, do not provide us with guaranteed computation results. In many situations, we have numerical ...

This work presents a set of measures to evaluate the structural complexity of business process models at a conceptual level, and also the general plan of a family of experiments whose aim is to validate the measures proposed. We believe that the early ...

Finding suitable actors to perform specific activities is a common problem in knowledge-oriented organizations. To address this problem, this paper outlines the concepts required to represent organizational actor's skills and the services that are ...

Organizations are modeled using several approaches namely behavioral-science approach, design-science approach [March and Smith 1995], classification approach [Zachman 1993], etc. Can all these different approaches be consistently reconciled? Can this ...

With the growing importance of enterprise architecture the discussion about how to create or choose the right enterprise architecture framework for a specific organization arose quickly. But it is not only a question of choosing the right framework for ...

The central idea in reference modeling is the reutilization of the business knowledge contained in reference models for the construction of specific models. The orientation on the content of a reference model can increase the efficiency of processes in ...

In this paper we will present the results of research into the semantics of modeling constructs for the process-oriented perspective for the conceptual modeling of enterprise subject areas. The set of modeling constructs that are defined in this paper ...

Based on changing market conditions and pressure on cost and productivity, companies in different industries have started do concentrate on their core competencies and to decrease vertical range of manufacture which leads to an increasing outsourcing of ...

Recent content-based image retrieval (CBIR) techniques were designed around query refinement based on relevance feedback. They suffer from slow convergence, high disk I/O, and do not even guarantee to find intended targets. In this paper, we identify ...

We propose an approach to create application-cooperation executable UML models by performing transformations on high-level business rule models. Business rules are defined, using activity diagrams, then, they are transformed to an annotated PIM to, ...

In this paper we discuss how to create and update diagrams after the execution of a model transformation. This is achieved by creating an independent diagram reconciliation tool component that is based on a mapping language from the abstract syntax to ...

Model transformations are frequently applied in business process modeling to bridge between languages on a different level of abstraction and formality. In this paper, we define a transformation between yEPCs which is an extension to the popular Event-...

In response to the lack of suitable methods to build the navigation model of Web Information Systems (WIS), we presented in past works HM³, the Hypertext Modeling Method of MIDAS, a methodological framework for the agile development of WIS. We proposed ...

Model transformations in MDA mostly aim at stepping from a Platform Independent Model (PIM) to a Platform Specific Model (PSM) from a functional viewpoint. In order to develop high quality software products, non-functional attributes (such as ...
