Over 85% of all new heat exchanger applications in oil refining, chemical, petro-chemical, and power generation are accommodated through the use of conventional shell and tube type heat exchangers. The fundamental basis for this statistic is shell and tube technology is a cost effective, proven solution for a wide variety of heat transfer requirements. However, there are limitations associated ...
Model predictive control (MPC) algorithm has been widely applied in industry process control systems since last century, like petro-refining and other chemical processes. However, it is rarely used in field controllers due to the complexity of online optimization. This paper introduces a new MPC system based on the field programmable gate array (FPGA) chip. In order to make MPC controller more ...

present research was conducted with the aim of determination of significant effect of soil properties on natural regeneration of haloxylon aphyllum and correlation coefficient and linear relation between soil variables and natural regeneration of haloxylon aphyllum. firstly, geomorphologic units were prepared in the areas under cultivation of haloxylon aphyllum in ardestan. two cultivated lands...
This article critically analyzes how far-right political male elites persistently deny climate change, a political-discursive strategy of maintaining the status quo, which has historically benefited them. Making use concepts such as «petro-masculinity» and «industrial masculinities», introducing concept «patriarchal Anthropocene», this paper argues that denial is inextricably linked to these le...
The present study aimed to analyze reprint request e-mail messages written by postgraduates (MA students) of two fields of study, namely Physics and EFL, to realize the differences and similarities between the two email types. To investigate the purpose of the study, a sample of 100 e-mail messages, 50 Physics and 50 EFL, were analyzed according to Swales’ (1990) model for reprint requests and ...
in this paper, a new fractional sub-equation method is proposed for finding exact solutions of fractional partial differential equations (fpdes) in the sense of modified riemann-liouville derivative. with the aid of symbolic computation, we choose the space-time fractional zakharov-kuznetsov-benjamin-bona-mahony (zkbbm) equation in mathematical physics with a source to illustrate the validity a...
