with the advent of cyberspace and development of data and information, virtual cities were presented as new forms of city management in different layers and territories. historic and tourism virtual city are among eight types of virtual cities. in this article some guidelines were presented in order to design and manage them based on tehran tourists' need assessment. theoretical framework ...

conclusions according to the results of the present study, aerobic exercise at moderate intensity and proper time can be considered as a special treatment to prevent diabetes complications and related disorders, particularly obesity. objectives this study aimed to determine whether in patients with type 2 diabetes, substrate oxidation and energy expenditure were affected by the type of intensit...

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.

While virtual networks have been subjected to detailed analysis, prototypes are usually constructed and instantiated manually or by means of dedicated control protocols that mostly neglect security considerations. As the instantiation and maintenance of virtual networks requires virtual network operators to gain access to existing network resources, a proper sender authentication builds an impo...

A lattice matched triple junction solar cell (TJSC) structure with a GaAs0.58 P0.42 top and bandgap tunable GaNxAs1-x-zPz middle bottom cells on virtual SiGe substrate is proposed in this study. SiGe/Si preferred as it low-cost because provides constant at which dilute nitride materials that are appropriate for highly efficient multijunction can be obtained. By changing the nitrogen content GaN...

Small ubiquitin like modifier (SUMO) specific proteases (SENPs) are cysteine proteases that carry out the proteolytic processing of SUMO from its pro form as well as the deconjugation of SUMO from substrate proteins. SENPs are attractive targets for drug discovery due to their crucial role in the development of various diseases. However, the SENPs inhibitor discovery efforts were limited, and o...

Network virtualization has emerged as a powerful technique to allow multiple heterogeneous networks specified by different users to run on a shared infrastructure. A major challenge is how to make efficient use of the shared resources. Virtual Network Embedding (VNE) addresses this problem by finding an effective mapping of the virtual nodes & links onto the substrate network. For some scenario...

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...
