Control flow elements are important in process models. Such elements usually appear in graphic models as splits and joins of activity sequences. Workflow patterns reflect possible executions of different configurations of splits and joins. However, despite the importance of process flow control and workflow patterns, no way exists yet to assure that a particular set of patterns is complete and ...

This paper introduces a notion of data ows and mode declarations for IntelligentPad, a kind of component softwares. The mode speci es how component pads are used for testing the behavior of composite pads. Under the constraints obtained from a family of mode declarations, we present an expansion procedure to generate hypothetical composite pads. An experimental result shows that the usages of m...

doppler ultrasound can provide important information about vascular problems through the analysis of blood flow wave-form. the purpose of this study was obtaining the normal images of color doppler and estimation of blood flow velocity parameters of femoral artery in rabbits. left and right femoral arteries of 8 healthy adult new zealand rabbits were evaluated. color and spectral doppler images...
