Adaptation is an important concept for Web processes. The author provides an overview of adaptation with respect to control theory and how it is applied to other contexts. Specifically the author focuses on open loop and closed loop adaptation. Then the cahpter discusses the current Web process standard WS-BPEL supports open loop adaptation. Finally, the author discusses an academic research fr...

The goal of this article is to examine the effectiveness of “for-loop” and “while-loop” statements on SCMPDS by insert sort. In this article, first of all, we present an approach to compute the execution result of “for-loop” program by “loop-invariant”, based on Hoare’s axioms for program verification. Secondly, we extend the fundamental properties of the finite sequence and complex instruction...

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

Contemporary information systems are generally built on the principle of segregation of data and processes. Data are modeled in terms of entities and relationships while processes are modeled as chains of events and activities. This situation engenders an impedance mismatch between the process layer, the business logic layer and the data layer. We discuss some of the issues that this impedance ...
