‎‎‎in this paper‎, ‎we develop multi-step methods to solve a class of two-dimensional nonlinear volterra integral equations (2d-nvies) of the first kind‎. ‎here‎, ‎we convert a 2d-nvie of the first kind to a one-dimensional linear vie of the first kind and then we solve the resulted equation numerically by multi-step methods‎. ‎we also verify convergence and error analysis of the method‎. ‎at t...

The globalised and moving economical environment leads enterprises to develop networked strategies. Such collaborative networks are by now often based on trusted and well known communities and require IT support agility and interoperability. The European Union promotes solutions to support and favor innovative business networks on the basis of an internet of services: these FP6 and FP7 projects...

In this article, I show that the term is commonly used as a synonym for studies of clinical effectiveness and/or economic evaluations and argue that further factors relating to everyday working practice should be included under its auspices. I go on to develop a ...

Aiming at the increasing requirements of seamless indoor and outdoor navigation and location service, a Chinese standard of Multidimensional Indoor Location Information Model is being developed, which defines ontology of indoor location. The model is complementary to 3D concepts like CityGML and IndoorGML. The goal of the model is to provide an exchange GML-based format for location needed for ...

We draw upon strategic management theory, organizational behavior theory, organization theory, and entrepreneurship models to form an integrated model of venture growth including 17 concepts from 5 micro/macro research domains. The model was tested with responses from 307 companies from the architectural woodworking industry. CEO's specific competencies and motivation, and competitive strategie...

Progression through the HIV continuum of care, from HIV testing to lifelong retention in antiretroviral therapy (ART) care and treatment programs, is critical to the success of HIV treatment and prevention efforts. However, significant losses occur at each stage of the continuum and little is known about contextual factors contributing to disengagement at these stages. This study sought to expl...
