The network calculus is a powerful tool to analyze the performance of wireless sensor networks. But the original network calculus can only model the single-mode wireless sensor network. In this paper, we combine the original network calculus with the multimode model to analyze the maximum delay bound of the flow of interest in the multimode wireless sensor network. There are two combined method...

The movement of items through a product distribution network is a complex dynamic process which depends not only on the network’s static topology but also on a knowledge of how each node stores, handles and forwards items. Analysing this time-dependent behaviour would normally require a simulation algorithm which maintains a globally-synchronised system state. For a certain class of problem, ho...

Abstract. The unsteady three-dimensional flow of couple stress fluid over a stretched surface is investigated. Analysis has been performed in the presence of mass transfer and chemical reaction. Nonlinear flow analysis is computed by a homotopic approach. Plots are presented and analyzed for the various parameters of interest. A comparative study with existing solutions in a limiting sense is m...

This article evaluates the extent to which the establishment of the Andean Free Trade Zone (AFTZ) has led to an improvement of intra-regional trade, as promised by open regionalism, without reducing extra-regional trade. Open regionalism is a dynamic process in which economic agreements serve as intermediate steps towards integration with the world economy. The calculations of ex post income el...

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...

Control-flow analysis of business process models requires to check the absence of lack of synchronization. We use workflow graphs, which may contain inclusive OR gateways, to represent the control-flow of business process models. We structurally characterize lack of synchronization in an acyclic workflow graph. Based on this characterization, we show how to detect lack of synchronization in qua...
