Multiple enterprises are usually involved in supply chain network, while almost each enterprise has its own information systems and databases (enterprise legacy systems). There are large quantities of information and data intersecting or even repeating with each other, which calls for system integration. Meanwhile in the cooperative process of supply chain, the whole product line or product fam...

The product data exchange between heterogeneous CAD and PDM systems is a crucial issue for the integration of product development systems. STEP offers an efficient mechanism of product data exchange between heterogeneous systems. This paper introduces a UML-based mapping methodology for the product data models. The suggested mapping method has been applied to exchange the product structure data...

in this study, the bernoulli polynomials are used to obtain an approximate solution of a class of nonlinear two-dimensional integral equations. to this aim, the operational matrices of integration and the product for bernoulli polynomials are derived and utilized to reduce the considered problem to a system of nonlinear algebraic equations. some examples are presented to illustrate the efficien...

In the context of simulation of electromagnetic propagation, the thin wire formalism of Holland and Simpson allows one to deal with scattering by perfectly conducting thin wires by coupling a standard FDTD method with a discrete 1D wave equation ruling the current inside the wires. This method can be very accurate, but it involves a fitting parameter that requires careful calibration. We propos...

In "Functional MRI Lie Detection: Too Good to be True?" in this issue of The Journal, Joseph Simpson reviews the merits and the limitations of using fMRI to detect deception. After presenting the gaps in experimental data that stand in the way of translating the laboratory proof of concept to a field application, Simpson surveys the legal, regulatory and ethics concerns facing fMRI, should it e...

The elusive relationship between information technology (IT) and business value continues to challenge academics and researchers. Recently, it has been suggested that a process-level framework that accounts for intermediate organizational factors is likely to allow us to better understand the antecedents of the business value of IT. This paper develops a model examining the impact of distinct I...
