Service-oriented architectures focus on the alignment of business processes and the supporting information technology. To facilitate the alignment and to decrease administration costs we propose linking of SOA services to enterprise models respectively target state organisational models by using semantically enriched conceptual modelling languages. Acting on language meta-level means in this co...

The Service oriented architecture Modeling Language (SoaML) is a new specification from the Object Management Group (OMG) that provides support for modelling services. The SoaML specification defines three different approaches to specifying services; simple interfaces, service interfaces and service contracts. In this paper we provide an overview of the SoaML language constructs and discuss the...

One of the issues that developers of service-oriented systems currently discuss is the lack of practical, but formal modeling notations and tools that can address the many different, important aspects. This paper presents an approach to model structural and behavioral properties of service-oriented systems with UML and OCL models. Essential service-oriented concepts as service request, service ...

Molecular clustering is the initial step of atmospheric new particle formation (NPF) that generates numerous secondary particles. Using two online mass spectrometers with and without a chemical ionization inlet, we characterized neutral clusters naturally charged ion during NPF periods in urban Beijing. In clusters, observed pure sulfuric acid (SA) SA-amine SA-ammonia (NH3) SA-amine-NH3 cluster...

by spectrophotometer, readings for all samples were higher than those for the 0 ng/L calibrator; OOM extracts provided signals that were well above those of the 400 ng/L calibrator. In summary, simple aqueous extracts from small portions of 6 different OOM-associated tumors revealed very high FGF-23 concentrations as assessed by the calibrator assay; FGF-23 concentrations were also readily dete...

An emergent domain that raises some unique engineering challenges is that of software architectures to convert large bodies of unstructured data to human-usable knowledge, such as in the domain of socio-cultural information analysis. We report on an architecture based on Service-Oriented Architectures that we are applying in this domain. We list the requirements that such an architecture must s...

We are investigating the application of aspect-oriented principles as an aid toward improving the capabilities of domain-specific modeling. The approach, in general, provides transformations by weaving modeling aspects into a base model. The modeling aspects provide variation points within the model and can be used to drive the synthesis of the model into different artifacts. In this brief posi...
