We discuss conformal symmetry on the two dimensional noncommutative plane equipped with Moyal product in the twist deformed context. We show that the consistent use of the twist procedure leads to results which are free from ambiguities. This lends support to the importance of the use of twist symmetries in noncommutative geometry.

The paper presents an architecture of a Petri net based framework for modelling and control of workflow processes. It focuses on the PNEditor module and briefly discusses workflow engine based on the models designed using the PNEditor. Then the paper describes method of synthesis Separating feasible places and an algorithm for reducing the number of places in the resulting Petri net.

PEWS is a language for the implementation of web service interfaces. PEWS programs can be used for the description of both individual and composed web services. Individual web services can be built up from Java programs. Composed web services are built from simpler services. PEWS operators describe the allowed workflow of the web service, i.e.the order in which the operations of the web service...

Abstract We introduce the concept of Canonical Workflow Building Blocks (CWBB), a methodology describing and wrapping computational tools, in order for them to be utilised reproducible manner from multiple workflow languages execution platforms. The is implemented demonstrated with BioExcel library (BioBB), collection tool wrappers field biomolecular simulation. Interoperability across differen...

This chapter introduces the basic concepts of information control net (ICN) and its workflow models. In principle, a workflow model is the theoretical basis of a workflow modeling methodology as well as a workflow enactment architecture. Particularly, the workflow model is directly related with how its major components are embodied for implementing the underlying workflow enactment system, too....

Collaborative information systems are becoming more and more complex, involving numerous interacting business objects within considerable processes. Analysing the interaction structure of those complex systems will enable them to be well understood and controlled. The work described in this paper is a contribution to these problems for workflow based process applications. In fact, we discover w...
