New concepts in thermodynamics are further extended and combined with a principle of virtual dissipation to provide general equations of evolution of collective open chemical systems. A new definition of the chemical potential is introduced, and some new expressions for the affinity are discussed. Application of the principle of virtual dissipation leads very simply to quite general continuum f...

This paper proposes a context approach of social networks and virtual communities in the enterprise area. We point out that making context explicit it is possible to provide a global picture of the main aspects of social networks. A first result of this study is that the explicit consideration of contexts—especially shared contexts—could improve notably the collaborative-work processes in an en...

This paper proposes a context-based approach of social networks and virtual communities in the enterprise area. We point out that making context explicit it is possible to provide a global picture of the main aspects of social networks. A first result of this study is that the explicit consideration of contexts—especially shared contexts—could improve notably the collaborative-work processes in...

in this paper, by investigating the common weights concept and dea models with nonlinear virtual inputs/outputs, we introduce a model for evaluating the decision making units with nonlinear virtual inputs and outputs based on the common weights.

Building on previous development, the A-Maze artists continue to develop ‘Boundless – Worlds in Flux a Virtual Reality platform with hub leading different Artists’ spaces. During 2021, team has reached out museums, site-specific communities, user groups and expanded include new design developers. This paper will chart this insights, challenges next steps. Insi...

abstract- this study aims to model optimal cultivation pattern based on the maximization of importing virtual water and social net income of major crops in marvdasht, iran. for this purpose, a linear programming model was developed considering constraints of virtual water and land limitations followed by other models to include employment restrictions. based on the findings, wheat and tomato we...
