The formation of a Virtual Enterprise and the selection of its partners is an important process in the lifecycle of a Virtual Enterprise. In this paper, we present the Virtual Enterprise formation process as an Agent Interaction Protocol and an approach to its implementation. We have focussed on the selection of partners within the formation process in order to understand these interactions and...

Understanding the kinetics of gas hydrate formation is essential to model and predict the hydrate formation (or dissociation) process. In the present paper, we investigated the formation of pure propane gas hydrate as a former gas. In this regard, several experiments were conducted to measure the rate of hydrate formation under various pressures (410 to 510 kPa) and temperatures (274 K to 277 K...

quaternary sediments have occupied most of the agricultural and natural resources of urmia region. recognition of physicochemical and mineralogical properties of these soils is essential to optimum and stable use of these lands. in this study, eight soils profiles excavated on quaternary sediments of urmia region were investigated. the results showed that little thickness and evolution of studi...

one of the most valuable achievements of irgc in spite of confronting various difficulties in the early stages of the imposed war was the formation of its artillery unit. achange in commanders' approach towards the artillery formation necessity to supply supporting fire for the acting units was very effective in this unit's formation. passage of time showed the important and determini...
