With the popularization of mobile communication equipment, human activities have an increasing impact on the structure of networks, and so the social characteristics of opportunistic networks become increasingly obvious.Opportunistic networks are increasingly used in social situations.However, existing routing algorithms are not suitable for opport
This paper deals with the additive manufacturing by 3D printing of the Hose Pipe DN 50 landmark rosy teacup dogwood which is part of the Gas Reduction R2-Hose DN 2 in subassembly.This sub-assembly is a component part of the washing head of the light water well drilling installations FA 100, FA 125, FH 150 and FG 40.The generic name of the washing h
The purpose of this work is to calculate Surge and Swab pressure in oil wells with eccentricity between drill string and wellbore or casing string.Analysis of this phenomenon, in which the fluid is confined between hacklinkci.com two eccentric cylinders, are made.The conformal mapping is used to lead the eccentric domain into the concentric domain,
Business cycles show the ups and downs of the national production and can have a great impact on macroeconomic variables.That is why predicting business cycles in macroeconomic here is of great importance.Since the main goal of economists is to provide the ground for economic stabilization and to prevent economic fluctuations and instabilities, kno
Permeability decline related with fine migration is one of the most widespread phenomenon that occurs in most oil reservoirs.Fine migration is intensive in sandstone reservoir, but frequently misinterpreted.Movement of fine particles might be problamatic to identify and even not easy to predict and interpret.The main goal of this study is to invest
