natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. the problem is a two dimensional developing buoyant flow. in this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. the results for the local nusselt number at the du...

Nowadays, electronic devices span a diverse pool of applications, especially when getting smaller and smaller satisfying the more than Moore paradigm. To further develop this, studies focusing on material design toward electronic devices are crucial. Accordingly, we present a theoretical study investigating the possibility of graphene as a promising material for such electronic devices design. ...

Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles.  Methods: A total of 80 players, aged 18 to 30 years, played four types of video games;  Ru...

The purpose of this research is to demonstrate how the pattern of play technologies follows the patterns of play types in developmental psychology. This research provides an overview of dominant theories in developmental psychology and offers evidence of its parallel in play modalities adopted by electronic game audiences. The fundamental benefit of such framing is the potential to offer a futu...

BACKGROUND Many children are reported to have insufficient physical activity (PA) placing them at greater risk of poor health outcomes. Participating in sedentary activities such as playing electronic games is widely believed to contribute to less PA. However there is no experimental evidence that playing electronic games reduces PA. There is also no evidence regarding the effect of different t...

The mobile internet expands the immersive potential of storytelling by introducing electronic games powered by portable, location-aware interfaces. Mobile gaming has become the latest iteration in a decades-long evolution of electronic games that seek to empower the player not just as an avatar in a gameworld but also as a co-author of that gameworld, alongside the game’s original designers. Lo...

1 BACKGROUND/MOTIVATION Most non-electronic games are designed for the physical world we live in and to make effective use of 'real world' properties, such as physical objects, our sense of space and spatial relations. Our sensory engagement in the world adds texture, context, and content to the game play. Computers inarguably offer exciting possibilities to the design of games but they also tr...

the usage of technologies for the treatment of patients is constantly emerging. A recent trend is the usage of games for healthcare, mainly in motor rehabilitation. The entertainment facet of the game attracts the attention of patients making them more engaged in the treatment. A difficult in the usage of commercial games is that they require full attention of the healthcare professionals, sinc...
