Data dissemination or diffusion service is the process of distributing a certain amount of information to the users such as vehicle drivers or mobile users especially in wireless networks. It also plays a significant role in numerous applications of Vehicular Ad hoc Networks (VANETs). Data Dissemination problem has been addressed by many researchers so far in many contexts. This paper presents ...

In 2000, Lee and Chang proposed a user identification scheme with key distribution preserving anonymity for distributed computer networks. Recently, Wu and Hsu pointed out that there are two weaknesses in the LeeChang scheme. They further not only proposed a new scheme to remedy the security leaks of the Lee-Chang scheme, but also reduced computation complexities and communication cost as compa...

in this work, studies of underground gas storage (ugs) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. results showed that di...

This work consists in a numerically evaluation of elastic fields distribution, caused by intrinsic dislocation networks placed at a nanometric trilayers interfaces, in order to estimate their influence on the surface topology during heterostructure operation. The organization of nanostructures is ensured by the knowledge of different elastic fields caused by buried dislocation networks and calc...

During the past few years, modeling in agriculture has attracted considerable attention. New modeling methods including neural networks are employed in various industries, and it is necessary that their use in agriculture be also considered. This research addressed the trend of energy use in broiler farms in Alborz Province and sought to model the trend of energy consumption and production in t...

Hydrogen technologies have been rapidly developing in the past few decades, pushed by governments’ road maps for sustainability and supported a widespread need to decarbonize global energy sector. Recent scientific progress has led better performances higher efficiencies of hydrogen-related technologies, so much that their future economic viability is now rarely called into question. This artic...

The consumption of buildings for the production heat is expected to decrease in Switzerland coming years, particular following policies encouraging refurbishment buildings. This will notably have an impact on natural gas network, parallel with penetration electric-driven pumps. Through a detailed optimization scheme, evolution (NG) distribution network studied over future period forty i.e. up 2...

Steel production in integrated steelworks involves the simultaneous of various byproducts, including process off-gases that are usually exploited for generating electricity internal power plant, heat and steam. Their discontinuous is managed through complex network, gasholders torches, which must be with stringent operational constraints. In this paper we present a supervision control system de...
