Experiments with network formation
We examine how groups of agents form trading networks in the presence of idiosyncratic risk and the possibility of contagion. Specifically, in our model, four agents play a two-stage, finitely repeated game. In the first stage, the network structure is endogenously determined in a noncooperative proposal game. In the second stage, agents play multiple rounds of a coordination game against all o...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Numerical modeling of pseudotachylyte injection vein formation
Pseudotachylyte, a fault rock formed through coseismic frictional melting, provides an important record of coseismic mechanics. In particular, injection veins formed at a high angle to the fault surface have been used to estimate rupture directivity, velocity, pulse length, stress and strength drop, as well as slip weakening distance and wall rock sti ness. These studies, however, have generall...
متن کاملAbsence of retromandibular vein associated with atypical formation of external jugular vein in the parotid region
Veins of the head and neck exhibiting anatomical variations or malformations are clinically significant. Anatomical variation in the external jugular vein is very common. However, anatomical variation in the retromandibular vein is rare. In this paper, we report a rare case of complete absence of the retromandibular vein. In the absence of the retromandibular vein, the maxillary vein divided in...
