In this paper, we present a virtual laboratory platform (VLP) baptized Mercury allowing students to make practical work (PW) on different aspects of mobile wireless sensor networks (WSNs). Our choice of WSNs is motivated mainly by the use of real experiments needed in most courses about WSNs. These experiments require an expensive investment and a lot of nodes in the classroom. To illustrate ou...

Quality education can be delivered at a time, place and pace that suit the learner, teacher and administrator. One way to achieve this is for universities to devise an appropriate and effective web based education environment that supports customization for the individual. Such an environment requires interoperability of heterogeneous systems, reduced cost through re-use of existing invested te...

INTRODUCTION The main scope of this article is to present a heuristic model to deploy government-to-government initiatives effectively, as well as establish some key success factors for building governmentto-government (G2G) enterprises successfully. It also aims to show how public agencies themselves can benefit when they are electronically linked to others, thereby innovating and streamlining...

As the underlying technologies evolve, embedded systems are finding their way into an increasing range of ABB products and applications. Advances in this technology lead to higher performance and more functionality on the one hand, and reduced cost and size on the other. While this benefits the end user, the ever increasing complexity of embedded systems imposes new challenges for developers. T...

I N T E R N A T I O N A L E X P E R I E N C E Around the world many fisheries have collapsed, including some in Australia. Consequently marine fisheries are under increasing pressure to adopt more precautionary management approaches. Although Australia’s fisheries are generally in good shape—few are overfished—many are fully exploited. Overseas experience tells us that even the best fisheries m...

We use the Litvinov-Maslov correspondence principle to reduce and hybridize networks of biochemical reactions. We apply this method to a cell cycle oscillator model. The reduced and hybridized model can be used as a hybrid model for the cell cycle. We also propose a practical recipe for detecting quasi-equilibrium QE reactions and quasi-steady state QSS species in biochemical models with ration...

As the number of applications that use machine learning algorithms increases, the need for labeled data useful for training such algorithms intensifies. Getting labels typically involves employing humans to do the annotation, which directly translates to training and working costs. Crowdsourcing platforms have made labeling cheaper and faster, but they still involve significant costs, especiall...

Globalization of operations, reduced time to market, increased need to respond quickly to customers’ needs worldwide and reduced cost of operations have encouraged many business organizations to adopt global virtual teams for their business activities. In this study, we explore a comprehensive model consisting of different variables that impact performance of such global virtual teams and valid...

The paper concerns the Hamiltonian structure of the finite-dimensional reductions 2D dispersionless Toda hierarchy constrained by the string equation. We derive the Hamiltonian structure of the reduced dynamics and show connections of integrals of “multi-finger” solutions of the Laplacian growth problem with the “Toda–Krichever” flows of the 2dToda hierarchy constrained by a string equation. Th...

Background and Objective: Because COVID-19 has become a pandemic, public health measures to cut off human-to-human transmission may include quarantine and social isolation. This study aims to demonstrate the effects of the COVID-19 pandemic on demographic variables and their relationship to the level of social participation during the pandemic. Methods: In June 2020, the community integration ...
