Vehicular ad hoc network (VANETs) allows vehicles to communicate to each other and to roadside units. This enables a lot of different applications which can bring safety, efficiency, convenience and other benefit to users and the traffic system. Therefore, it received huge attention from academic area, government and manufactory. This paper focus on the security issues of the system. We are goi...

Polycyclic aromatic hydrocarbons (PAHs) have been used as graphene’s model of electronic structure characterization [1]. Since the initial graphene experiments, it has been used in several areas, such as sensors manufactory, organic semiconductors, spintronic and non-liner optics and the study of its electronic structure is very important for these applications [2]. Therefore, the characterizat...

seed germination is a crucial stage in the plant life cycle and salt tolerance during germination stage is vital for the establishment of plants in saline soils. in order to evaluation of sesame (sesamum indicum) landraces germination to salinity stress at different temperature, an experiment was conducted at ferdowsi university of mashhad, collage of agriculture during 2009. experimental type ...

We study the traffic of two types of molecular motors using the two-species asymmetric simple exclusion process (ASEP) with periodic boundary conditions and with attachment and detachment of particles. We determine characteristic properties such as motor densities and currents by simulations and analytical calculations. For motors with different unbinding probabilities, mean-field theory gives ...
